Home Audio Speakers: Choosing A System For Your Home Theater Design

Creating the perfect home theater involves more than a great TV. This article provides an overview of the different speaker styles available to people setting up their home theater.

With over 500 models of home theater speakers available through a generous number of high and low-end brands, many consumers rely on salesperson to lead them in the right direction.  Consumers with only a limited budget will undoubtedly flock to the cheapest option available to suit there needs. This however, nearly always results in a less than ideal sound system that fails to meet the expectations or needs of the owner. It is therefore a good idea to educate one’s self on the best brands, speaker styles and specifications that will fit a home’s needs before making a choice.

A home theater speaker system is typically made up of a front speaker, left and right speaker, a center-channel speaker, a pair of surrounds, and a subwoofer. A home owner may mix-and-match components but help from a professional is advised to make sure the speakers are all compatible.  These speaker types come in varying sizes, sound output and design. The following are the types of styles in which these speakers may be found:

Floor-Standing speakers are the largest home theater speakers available.  They can be shifted around the theater area or be moved to another home. 

Bookshelf or Cabinet speakers stand independently, just like floor standing speakers, but are smaller and can be placed on or in entertainment centers or shelving to save space.

In-Wall speakers require no floor space, and can disappear if matching the walls.  Their quality is usually very good, but they need professional installation and wiring.

On-Wall speakers are recommended for use with a flat-panel television. They provide exceptional sound as well as a pleasing aesthetic component.

Home theater owners or designers must determine the listening requirements and preferences for a specific room in order to create a quality home theater space.  Room size and layout are important factors as this will dictate the speaker configuration. Logistics like electrical outlet placement, room size, and useable room space strongly affect the type of equipment that can and should be put in the room.

Home theater speakers are available in many sizes. However not all sizes are meant for all rooms.  Large speakers are not advantageous for small rooms because they will need to be played at a much lower volume. This may cause distortion to the audio.  Lower quality small speakers used in large spaces may produce a tinny or thin sound if they are unable to produce enough sound at a decent output level.  Speakers of similar size may differ greatly in their sound output or reproduce different levels of sound unequally so it is very important to listen to various speaker brands and sizes and compare them before buying.

Speakers are available in a variety of encasement types - natural or laminated wood, metal, and occasionally plastic, but often preferences may be limited by brand or model. Speakers are as varied as tennis shoes so make sure you try on several and know how they fit into your home theater before making a purchase.

High Definition Stalemate

For those who have not yet settled on which high definition disc to invest in, this article will help bring several issues to light. First of all, the potential video and audio quality remain alike between both formats, HD-DVD and Blu-Ray. The difference lies in the laser that reads the disc; where the former uses the identical red laser used to read DVDs, the latter employs a blue laser that reads only Blu-Ray. Both lasers can decode an identical amount of information, called the bitrate. A bitrate can be labeled as the amount of "bits" decoded per second. Generally, the higher the bitrate the higher the quality of video/audio. So a bitrate of, say, 30mbs (megabytes per second) should be preferable to a meager 10mbs. The average hi-def picture, with its superior clarity and contrast, can maintain a bitrate between 15mbs-35mbs; compare this with an ordinary DVD, which averages 2mbs-7mbs.

With its ability to store and transmit at a higher bitrate, hi-def media easily trumps the quality of DVD. This higher bitrate allows for less compression, and thus can retain most of the clarity from the original master print of a movie; whereas a DVD will look blown-up and fuzzy. But the differences between HD-DVD and Blu-Ray begin with how they can be played. HD-DVD players have the advantage of backward compatibility, as it can playback DVDs. Blu-Ray players cannot, due to their unique laser, which completely isolates it from older generation technology. But the advantages of Blu-Ray lay in its inherent differences.

Blu-Ray players come equipped with Java software, which some believe to allow more interactivity with the user. This gives it the ability to have fancier menus and in-depth bonus options, such as picture-in-picture display. At the moment, bugs and slow performance have hindered some confidence in its support of Java, where Bill Gates complained that it was not user friendly enough to be used in PCs. Counter this with HD-DVD, which uses Microsoft's own HDi Interactive Format. It allows anyone to author simple content, where Java requires a more intimate knowledge of scripting.

If all the information so far sounds redundant, it is. The only thing that can make or break a hi-def entertainment center does not stem from the format at all. In fact, it all depends on what you choose to display it on. Be weary of interlaced televisions. Rather than playing back video at 1080p (progressive), the user gets short-changed with 1080i (interlaced). Progressive scan means that the picture gets scanned upon each frame; this results in a properly displayed picture, like a solid photograph, with no aberrations. Interlacing occurs when no progressive scan exists in the television, and so the picture gets displayed as a series of individual lines rather than as a single, uniform "photograph." In short, the fine edges in a progressively scanned movie may otherwise appear to be jagged, or even fuzzy, on an interlaced display.

The only reason to get invested in the so-called format war would be to avoid a costly personal investment if "your" format ever loses. Blu-Ray may be considered to be the superior technology, as its unique blue laser, while radically different and incapable of DVD playback, allows for exciting future developments. HD-DVD, largely compatible and user-friendly, is considered by some to be a static technology. Lately, however, Toshiba released its plan to market the format as cheaper, practical alternative to Blu-Ray. And, in the event that you still cannot make up your mind, there exists a combo Blu-Ray/HD-DVD/DVD computer drive that sells for less than $300.

Headphones Make The Grade

Too often, someone buys a new portable audio device and thinks the supplied earbuds are going to do justice to the quality player.  Stock buds are always the lowest grade, so as to minimize overall product cost.  Learn about after-market headphones here.


Too often the weakest link in a portable audio setup is the headphones

Many portable music enthusiasts spend a great deal of money trying to improve on the quality of their music by buying the highest quality CD players, MP3 players, stereos, and speakers.  Then they spend most of their time listening to their portable audio devices through the cheap headphones that came with the devices or something they picked up at the local discount store.  Good headphones should be the primary concern in most cases where portable audio quality is a primary consideration.

The cost of headphones.

The good news is that great quality from headphones is much less expensive than getting great quality from the other audio components.  A good set of headphones will often provide you with a better sound experience than a very expensive set of speakers.  So if you're going to spend for the best audio quality, the primary concern should be on purchasing great headphones.

Many people make the mistake of not even buying headphones at all. Almost all portable audio devices now come with their own little headphones.  In most cases these are not even brand name headphones, but rather mass manufactured headphones that have a market value between $1 and $10.  Even when they are brand name headphones, they are often at the bottom of that brand's product line.  Using these headphones greatly compromises the sound quality of the music you listen to on a daily basis.  So as long as you're going to invest in a portable audio player with all of the features you want, invest in a good set of headphones as well.

Headphones and location

Primarily we use headphones so that we can listen to music wherever we go without rudely imposing our music preferences on those around us.  Think about the various places where you listen to music and where you would like to listen to music.  How much better does great sounding music make you feel about each of those places?  If you're going to take your music with you, make it great.

These are not your grandpa's headphones

Headphones were once big metal, wood, and then plastic speaker systems that hung on giant headgear on top of your ears.  Over time they got smaller, became more comfortable, and provided better sound. This trend in headphones continues today.  While earpieces have been available for a few decades now, the moderately priced earpieces we have now provide sound quality that only the best speaker systems of the past could compete with today.  But that doesn't mean you should settle.

If you can have the sound of a concert hall, why settle for the sound of bad headphones?  Take a little time and spend a little money to make sure you get a great sound experience from your portable audio devices with a great set of headphones.

HDMI and DVI, Similarities and Differences

The HDMI and the DVI cable are two completely new types of cables. Learn about what these two types have in common and what their differences are. HDMI and DVI cables for your home theatre or any other video setup.

If you just acquired a new HD television, a television complete and equipped with the right HDMI connectors for attaching a DVD or Blue Ray disk player with HDMI interface, you will definitely need a the right kind of HDMI cable to make the connection. Other wise you won’t be able to use the high definition capability of either your television or your disk player and cable or satellite box.

You need to pay attention to the component outputs as well as inputs so you can plug in the HDMI cable and connect your television. In every instance where you use electronic devices, home or office, you must have the proper cables for them to work properly. Most of the time electronic devices such as televisions will not work properly or to their full potential if you don’t use the right cable connectors.

There are however do many different options out there, so many cables to choose from, so you will need to be prepared and know which one to choose so you won’t waste your time and money. With so many different cables out there and electronic equipment sales men and women making a living off commission the buyer ought to be careful when selecting HDMI cables. These types of cables can be very expensive, and consumers buy ones they don’t really need or can’t really use, very often.

The two most popular types of HD cables are HDMI cables and DVI cables. Although, they are similar in many ways they have many subtle differences that you need to have in mind. HDMI cables as well as DVI cables are not cheap.

Be careful know the differences and don’t waste your money. The DVI cable was released in the late 1990’s and DVI stands for Digital Visual Interface. The DVI is capable of carrying uncompressed digital video to a display, a monitor.


The first use of the DVI cable was associated with connecting the personal computer with a monitor. Over the past years however, their use expanded and they are now used to for connecting televisions as well. There are also different types of DVI cables as well. For instance there is the DVI-D, D for digital,  refers to digital cable, DVI-A is for analog television and the last one is DVI-I the one that accommodates for both digital and analog interfaces.

DVI cables in general are considered relatively outdated in comparison to the more recent and in high demand HDMI cable. HDMI stands for High Definition Multimedia Interface. The HDMI cable is relatively newer than the DVI, it as introduced in 2002 and came out as high definition televisions did.

The HDMI cable is an all-digital, no analog, video interface cable that can transmit uncompressed streams of data. That means that any HDMI cable even if it a Cheap HDMI Cables, can carry both audio and video signals. Both cables will work fine in getting the image to your television screen The HDMI is to considered better because of the two because of the fact that it is all digital.

Guide in Buying HDTV

I wrote this article originally for the HDTVetc magazine for the August 2003 issue, and it was later published on the HDTV Magazine in 2006. Consumers still go through the same struggle at national-chain stores today.

I updated the article to include current HD equipment and technologies. Its tutorial substance and analysis are still applicable today, and are intended to help consumers in making the right purchasing decisions. Enjoy the reading.


The following topics are covered in this segment:

1. H/DTV and NTSC TV Systems, What are they?
2. The First Effort of the DTV Transition
3. Quality HDTV, or Quantity DTV, or Both?
4. Backward Compatibility with Legacy Analog TV for Digital Broadcast
5. Satellite/Cable, and the DTV Transition
6. Tuner Integration
7. The Effect DVD had for DTV
8. The Rush for Knowledge

You have been hearing about HDTV and decided to start looking for one. A friend of yours reminds you that the general knowledge about buying regular TVs from the CRT analog era is not sufficient to select a digital product today, so you quickly review what you read about widescreen, black bars, digital tuners and resolution, and hope things would clear out at the store.

You get into the typical nationwide consumer electronic store most people go to, and suddenly see several dozens of HDTV demo sets staring back at you. A salesperson is approaching you, the person's face is familiar; the salesperson is the one that sold you the new dishwasher two weeks ago; now the person is selling HDTVs with authority. At that point you start feeling worried, but you hang in there.

Obviously this store is not a quality dedicated A/V retail place. Many consumers make their purchases based on the uninformed advice of untrained staff from typical nationwide consumer electronic chains.

In the near past, a typical store could only have one of those HDTVs actually displaying HD, the only one that had an HD tuner; the rest were showing the same image from a video distribution loop not suitable for HD quality.

Today perhaps the whole store feed is all HD, and the sets that are staring at you show the same picture, but with different colors, contrast, image enhancements, blacks, whites, etc. because no one bothered to set them correctly. So you start wondering why HDTV is not consistently perfect as is being preached, is that what HDTV is about?

The sales person turns toward you and, in the middle of your consumer panic attack, tells you: "trust me, buy this TV, it would look much better at home once connected to an HD tuner". Would you buy a car without test-driving it?

Millions of people went through similar experiences since HDTV was introduced in November 1998. Fortunately, some improvement is gradually seen in the stores, especially in dedicated A/V retail stores, which should take more time to help consumers understand the concepts behind each display technology, and not just quickly sell the HDTV inventory with the red tags, as most national consumer electronic chains do.

Most consumers love red tag savings, and many leave the stores wallet-happy with a product they do not understand. Perhaps many of those do not actually want to understand because the HDTV technology has been introduced with a complexity level they refuse to deal with to just get a TV.

To illustrate the complexity of an HDTV purchase decision you might want to read Is HDTV Complex Enough?

The objective of the article you are reading is to help you make your purchase with more confidence, but first allow me to cover the following basic subjects about HDTV:

H/DTV and NTSC TV Systems, What are they?

You might already know of the US plan to replace our current analog interlaced TV system (NTSC) dated from the 1940's by a digital DTV system, by February 17, 2009. Curiously enough the idea started as "analog" HDTV until General Instruments proposed an all-digital system in 1990.

The DTV standard is composed of 18 digital formats grouped into two levels of quality, as approved by the ATSC (American Television Systems Committee) in 1995:

1) SD: Standard Definition, with 480i/p (i:interlaced, p:progressive) viewable horizontal lines of vertical resolution (rows counted from top to bottom), each line with up to 704 total pixels of horizontal resolution (counted from left to right), and with an aspect ratio (relation of width to height in units) of 4x3 (as regular TV), or widescreen 16x9.

2) HD: High Definition, with 720p and 1080i/p viewable horizontal lines of vertical resolution (rows counted from top to bottom), each line with respectively 1280 (for 720p) or 1920 (for 1080i/p) total pixels of horizontal resolution (counted from left to right), and only in widescreen 16x9 aspect ratio.

Note that, because is not complex enough, the horizontal lines (rows) are expressed as "vertical" resolution (480, 720, 1080), and the vertical columns made of the aligned pixels on the horizontal lines are expressed as "horizontal" resolution (704, 1280, 1920).

DTV was 15 years in the making before it went on the air in November 1998. HDTV is the quality part of DTV, but its implementation is not mandatory, SD is. I will use the term DTV only when addressing the digital TV system in general.

Later in 2000, the Consumer Electronics Association (CEA), allegedly to help confused consumers, created another resolution level in between: ED (enhanced definition).

This promoted the 480p SD format to ED level, leaving only the 480i format in the SD level. It also granted any TV the right to be labeled HDTV if capable to display only 810i lines of vertical resolution within the displayed image, rather than 1080i.

One can argue how much this intervention from the CEA helped consumers more than helped manufacturers getting rid of mediocre sets. But that was back when CRT based DTV sets were the strength of the market; now most DTV sets are fixed pixel displays and their resolution is clearly specified as a pixel count in both directions.

Our current NTSC over-the-air (OTA) TV system is 480i analog interlaced (actually 525i with 480i viewable horizontal lines of vertical resolution). The regular channels of digital satellite and digital cable could be compared to digital SD of broadcast DTV, but they are also transmitting dozens of channels in HDTV.

To facilitate the transition, broadcasters were given one extra channel slot from the FCC for the simultaneous broadcasting of the analog and digital versions of their programming. It is a large investment for TV stations to build a DTV facility with new cameras, production, equipment, etc.

When DTV is fully implemented, broadcasters have to return one of the two channels, analog over-the-air broadcasting will stop, and current analog TVs, VCRs, TiVos with analog tuners would stop "tuning" as well (but they will still work as display devices if fed with a 480i analog signal from a converter, VHS tape, DVD player, etc). This date was originally set for January 2007 but has been extended to February 17, 2009. Once DTV is implemented, the FCC will auction that spectrum of airwaves.

Most OTA terrestrial TV stations are already broadcasting DTV in SD and HD widescreen, and consumers are buying HDTV sets at accelerated pace every year.

The First Effort of the DTV Transition

Just a look back at CEA's 2003 statistics, on the first 5 years of HDTV approximately 6 million DTVs (of which only 300,000 where integrated with DTV tuners) and 400,000 tuner set-top-boxes (STBs), were sold between 1999 and 2003. By the end of 2007, the HDTV count was 8 times fold, and about 50% of households have digital TV sets, according to the CEA.

Back in 1998/9 it was not unusual for first generation HDTV monitors to cost $10,000, and HD STB tuners to cost from $700 to $3,000. It was expensive for early adopters.

By the end of 2007, a huge variety in technologies and TV sets was available for every viewing environment. DTV sets are much better in quality, and sell for a small fraction of the price they sold back in 1998.

Quality HDTV, or Quantity DTV, or Both?

We all love the incredible video quality of HD, however, since HD is not mandated within the DTV plan, it allows a broadcasting station to use the allotted 6 MHz space (for the HD channel), to multicast instead several sub-channels of lower SD quality, as it is actually happening on many stations across the US.

When sharing the same 6MHz total bandwidth, SD sub-channels rob about 2-3 Mbps each from the needed bandwidth of an HD channel that by itself should broadcast at 19.4 Mbps (if the station also multicasts an HD sub-channel). The parallel broadcast forces further compression of the 19.4 Mbps HD signal to a lower bit rate to make room for the SD sub-channel, compromising HD quality.

In many cases, more than one SD sub-channel is multicast together with the HD sub-channel. When the reduced HD bit rate compresses the signal beyond acceptable limits, it renders a lower quality image with noticeable artifacts, especially on fast moving images in sports, which are more evident, and unacceptable, on large screens (more on it later).

It might also be possible that the TV station desires to share some of the bandwidth for data-casting interactive services, or for mobile DTV applications for hand-held portable devices (because there will be no analog broadcasting to those portable devices as well). For more information, check the articles I wrote on the "Mobile DTV" series, where I analyze the potential impact of mobile applications on the quality of an HD channel when robbing from its bandwidth.

We all hope that HD will reign, and HD quality will prevail over the digital-quantity business models, and you have to encourage DTV broadcasters to do so, besides, most consumers bought an HDTV not a SDTV.

Backward Compatibility with Legacy Analog TV for Digital Broadcast

When the DTV broadcast is fully implemented in February 17, 2009, there would be backward compatibility with your current analog equipment, but there is a catch, in order for you to watch DTV terrestrial digital channels on your current analog TV you would need a digital over-the-air STB tuner connected to it. Your current analog TV would display an analog interlaced 480i version of the digital image.

There is no need to rush for the replacement of an analog TV that might be in good working condition if you just want to continue watching similar quality TV, but you would have to buy a STB digital tuner for broadcast DTV.

This applies also to your analog VCR, DVD recorder, TiVo, etc., if you want them to have broadcast tuning independence. A few years ago, DTV STB tuners were relatively expensive, in the $400-$1000 price range, imagine buying a $400 digital tuner for a $30 analog VCR, but they are gradually coming down in price.

The US government has approved a subsidy coupon program to help people purchase DTV tuners to facilitate the analog-to-digital transition so existing analog TV sets can continue to be used for broadcast digital DTV.

For that purpose, Congress approved a fund of $1.5 billion dollars, with an initial allocation of $990 million dollars to subsidize up to two $40 coupons per household. The coupons became available in January 2008 and can be requested by consumers until March 2009, to use them toward the purchase of two DTV tuners.

The two coupons cannot be used together to purchase only one DTV tuner, neither they can be used to buy another type of OTA tuner/DVR STBs, satellite STBs with broadcast DTV tuners into them, or cable STBs.

The tuners offered by this program are expected to cost in the $50-$70 range each; the consumer would have to pay the difference after applying the $40 coupon. According to the plan, the tuners would become available by mid February 2008 through the national chains of Best Buy, Circuit City, etc.

Although the subsidized tuners are designed to tune digital SD and HD channels, they cannot output the tuned signal other than 480i analog resolution to an analog TV. In other words, the subsidized tuners would not perform as typical HD tuners passing resolutions of 480p, 720p, or 1080i to HDTV devices for HD viewing. Their functionality is just to downconvert because their purpose is backward compatibility to analog TVs, but their price is lower than typical ATSC HDTV tuners with variable output resolutions and digital outputs.



Satellite/Cable, and the DTV Transition

If you are a satellite subscriber you already have the satellite STB you need for their digital SD/HD services. Additionally, most satellite boxes also have a terrestrial ATSC tuner if you want to get free local channels using a VHF/UHF antenna. However, DirecTV introduced a new model in late 2007 without antenna input; the local channels would have to be viewed from the satellite feed, a service they have already for most major cities.

If you are a cable subscriber, when the cable company decides to disable the analog feed to your household and supply only the digital feed, you would need a digital-to-analog cable STB to view the digital channels on each analog TV in your house, similar to the approach of the coupon program for broadcast DTV above, but you would have to lease or buy the cable STB, no coupons.

Cable companies were authorized by the FCC in late 2007 to continue their analog feed service for another 5 years (up to 2012) if they prefer, but they are not obliged to do so. Cable STBs do not have DTV digital terrestrial tuners into them so you cannot use their STB connected to a UHF/VHF antenna to receive free local channels.

Cable companies face at least two alternatives on the analog-to-digital transition between 2007 and 2012:

a) If their subscriber base is mostly digital, a cable company might have the incentive to make a large up front investment to acquire enough digital STBs to convert all the remaining analog subscribers as soon as possible to digital tier services, who would have to lease one digital STB for each analog TV. That would release the bandwidth occupied by the analog broadcast channels on the cable feed, which could be used for additional digital channels, and receive an increased revenue if those are premium, VOD, PPV, etc. paid services.

b) If the subscriber's base is mostly analog, a cable company might prefer to keep the existing mix of analog and digital STBs, and maintain the analog tier as long as needed until 2012. Since the cable feed bandwidth allocation for the analog broadcast channels must continue with this alternative, the company would have to postpone the potential growth of digital channels and services, but there will not be a need for an up front large investment for expensive digital STBs because there is no forced conversion. This option seems economical for both the company and the subscriber, because a subscriber would not be forced to lease a digital STB for each analog TVs that might be currently connected to the wall coax without a STB, as many non-primary TVs are in most households.

While the up front investment of a large number of digital STBs could be expensive to a cable company, there could be a partial offset with the potential revenue received from additional digital pay services such as VOD, PPV, or premium channels. Additionally, the number of digital STBs required for a full digital conversion of the cable feed might be further reduced when considering the growing base of integrated HDTVs with CableCARD tuners expected to increase in 2008 and 2009.

However, since the integrated CableCARD tuners within HDTV sets are only unidirectional, there might still be a cable subscriber's base that would still require the bi-directional capabilities of cable HD-STBs for VOD, PPV, and cable supplied programming guide. Each cable company would have to balance those factors until 2012.

Tuner Integration

In 2002 the FCC issued a "mandatory" plan to gradually integrate digital broadcast tuners into DTV monitors and other tuning devices, such HD DVRs. The plan has been already implemented in 2007 for all the sets larger than 13", and all DTVs on sale today are mandated to include digital terrestrial tuners (except for some industrial/professional models). In most cases they also include a cable on-the-clear tuner for non-premium unscrambled channels, or even include a CableCARD tuner for premium channels and services.

As mentioned above, the CableCARD tuners are unidirectional only, and lack the bi-directional features of Video-on-Demand, Impulse Pay-per-View, and cable-company supplied programming guide, for which a separate set-top-box from the cable company would still be needed until integrated TV sets are designed to have bi-directional capabilities on their integrated CableCARD tuners.

Industry analysts commented for years that economies of scale would bring down the price of digital tuners to the level of today's very low price analog NTSC tuners within TVs, but the reality is that STBs for ATSC terrestrial, or for cable, satellite, DVRs, etc. (not the down-converting government-coupon STBs) still have a high price, considering that comparatively, large HDTVs came down from the $5,000-$10,000 in 98/99 to more accessible prices below $1000.

More on this subject is covered further down.

The Effect DVD had for DTV

Most of the 6 million people that bought HDTVs on the first 5 years of the transition (98-03) did so NOT to view HD, but rather to enjoy playing widescreen DVDs at 480p. Even now in 2008, after Hi-Def DVD has been already introduced in early 2006, regular DVDs are still a favorite content for DTV, because they certainly display quite well as progressive 480p, or upscaled to 720p or 1080i/p to the native resolution of the digital set (by either the DVD player or the TV set). The same DVD played on an analog TV would only show the image as a 480i interlaced scanning.

In addition, an HDTV has the capability to show widescreen DVDs in anamorphic format displaying all the original vertical resolution stored on the disc, while 4x3 analog TVs would show the same DVD letterboxing the image between larger top/bottom bars in order to maintain the wider aspect ratio of the movie, and with less vertical resolution for the image itself.

Enhance Your Home Theater Experience with HDMI Cables

Want to make the most of your home theater system? Enhance sound and picture quality with HDMI cables...

A top quality home theater isn't only about high-definition televisions and DVD players. It's also about the cables used to transmit programming through to these products. A type of cable that's proving to be a winner in excellent quality is the HDMI cable. HDMI stands for High-Definition Multimedia Interface, which is an audio/video connector interface used to transmit uncompressed digital signals.

HDMI provides audio/video cables that will connect electronics such as an HD-DVD player, a personal computer, a set-top box, a video game console, or a Blu-ray Disc player to a digital television monitor or digital audio device. HDMI cable compatibility has also been introduced to the digital camera and camcorder world.

Why HDMI Cables?

The old saying goes, "If you're going to do something, do it right!" Any high quality home theater set-up is only as good as the cables used to transmit the digital information. You can have the best, most expensive HD-DVD player in the world, but your low-quality cables will hinder the sound and picture quality because the transmission is simply not good enough or powerful enough for your system to reach its maximum potential. With HDMI, you're getting a high-quality transmission to your high-quality system, which maximizes the quality of sound and picture as you view movies, use your computer, play a video game, listen to music, or whatever else!

HDMI Cable Features and Benefits

Regular analogue cables convert the digital signal to analogue and then send it to the television monitor. The signal is then converted back to digital to be displayed, which can cause a loss of quality during the process. With HDMI cables, no conversion is necessary so there is no loss of quality. HDMI cables also transmit digital signals directly and in their purest form, eliminating the need for compression.

Another benefit is HDMI can support large-screen viewing including plasma display panels and LCDs, from 625p up to 1125p, or even 1440p with HDMI 1.3 High-Speed cables. HDMI cables simplify the hook-up process because both video and audio signals are transmitted through a single cable. Also, HDMI cables offer users an interface that works with any audio/video source. In other words, all of their HDMI-equipped components can be enhanced with pure quality for pictures and sound. HDMI cables can support standard digital audio as well as enhanced and high-definition video, and 8-channel digital audio. HDMI cables can also support future upgrades with plenty of bandwidth to spare.

Shopping for HDMI Cables

HDMI cables come in different compatibilities, but fortunately the High-Speed HDMI will support standard systems. If you plan to upgrade in the near the future, it's a wise choice to go ahead and purchase the High-Speed cables, or 1.3 cables, which can transport 1080p video at 120 Hz easily. Any HDMI cable can support 8-channel audio, but not all cables will support special features such as Deep Color video. With Deep Color HDTV, look for a version number on the cables or for other hints on the packaging that the cable will support 30-bit Deep Color or True HD.

You can easily find HDMI cables at affordable prices online. There are online electronics stores that offer all versions of HDMI cables along with other products including computer cables, iPod accessories, computer fans, video cables, audio cables, chargers, adapters, cell phone accessories, digital photo accessories, and more.

Don't miss out on all your home theater system can offer. HDMI cables can bring you quality pictures and sound like never before!

Emerging Mobile Phone Technologies

Mobile phones have become indispensable and now play a big part in everyone's lives. With the current technology that has made people and nations closer, mobile and handheld devices can truly be considered great inventions and innovations.

Mobile phones have become indispensable and now play a big part in everyone's lives. With the current technology that has made people and nations closer, mobile and handheld devices can truly be considered great inventions and innovations. Gone are the days when one has to go home first before he can use the telephone or go to a public phone booth to place an all-important call to a loved one or business contact. With the presence of mobile phones, everyone has now gone wireless. Communication has, indeed, turned very easy for all.

Mobile phone, as it name suggests, provides mobility. It is portable communication device. One can bring it anywhere. It is made possible by satellites that transmit signals for the phone to send and receive. It is very convenient as one can use it anywhere irregardless of time and region.

People everywhere have seen the evolution of communication technology. From a phone that uses wires to one that no longer requires any. From the analog to the wireless. In some places, wireless phones were provided with signals by the network company. In other places, a simulated card in inserted in the phone to grab and receive signals and send as well. These phones use the concept of signal transmission and radio wave theories that enables a two-way communication with real time and clearer conversation. 

From the analog mobile phones that only allowed calling and voice conversation evolved the mobile phones that have text messaging features. It is another emergence in the world of mobile technology. A person may send a text message that will be received by another party. This message is sent through a signal passing to a gateway which transmits it to the receiving party.

In the turn of the 20th century, mobile phones have become more of a trend and companies have started to make them appear more sophisticated. Mobile phones started with big sizes which transformed to smaller ones and then became bigger again. It has developed much like how computers have. Nowadays, mobile phones are not just for communication. Originally, it had the voice call function but since the technology is growing day by day, the mobile technology grows along with it. Mobile phones now have been created with different functions and usage which are beyond plain communication usage. These functions are constantly updated and additional features are created each day.

Mobile phones also serve as mp3 players and/or audio, video file storage units where users may save audio files and listen to the music. Mobile phones now are also equipped with cameras that come in different pixels allowing people to take pictures anywhere and anytime. Almost all mobile phones of these times are designed with games, calculator, organizer, alarm clock, dictionary and many more. These are just now considered the basics. Some updated mobile phones may now take video clips and still photographs of which may be transferred to the computer for different purposes. Many mobile phones are also designed with   touch screen features where a person doesn’t need to touch the keypad anymore. The screen of the phone is designed to recognize commands as the finger tip touches the screen.

Moreover, mobile phones are now used as computers. With the General Packet Radio Service (GPRS), surfing the internet is now made possible. GPRS is used to transmit IP packets which enable users to use the internet wherever they go. People also use their mobile phones in banking transactions where they can send and receive money through phone.

Several high technology features are continuously being researched and applied to mobile phones. Not long ago when 3G system was developed. It enables users of the same networks call each other with real time camera. Through this system, one can actually see the person he is calling while talking to him. Long before people finally get familiar with the just launched 3G system, many companies are now researching on the higher system which is the fourth generation or 4G system. Researchers project the new system as faster with a connection speed reaching 100 Mb per second. This is seen to provide a better quality of call. 

Mobile phones are not only for personal use like it was in the past. With mobile phones, reporters and journalists may now take and film news reports. Security system and surveillance are also possible. 

It is seen in the near future that mobile phones are most likely to replace laptops. With the new mobile phones coming out of the market, viewing and working on documents only found in computers are now possible. It is also seen to replace entertainment devices with all the entertainment features new mobile phones have.

Mobile phones do not only play a big part in technology. Mobile phones also show fashion and style. Thus, to make these phones more appealing and attractive, manufacturers produce these phones in different colors, size, shape, and style. 

Mobile phones are indeed one of the greatest contributions of technology. It has gone far beyond what man can imagine. Now, with the emergence of mobile technology, everyone just can’t live without one.

Developments In The Barcode Tags And Scanners Industry

The emergence of technology in transportation, communication, computer and entertainment has long been observed by people. And with the development of these high technology inventions, the need for safety and security arise.  Technology has also seen this need which led to the development of barcode tags and scanners.

The emergence of technology in transportation, communication, computer and entertainment has long been observed by people. And with the development of these high technology inventions, the need for safety and security arise.  Technology has also seen this need which led to the development of barcode tags and scanners.

A barcode is a representation of information. It is readable by a machine called scanner. The barcode is printed on a small piece of paper called tags. The barcodes are printed with dark ink usually with a white background. This is done to create a high and low reflectance allowing the scanner to convert the code into binary language. This way, the scanner can read the code. In the past, barcodes were stored in the spaces of paralleled lines. But technology made it possible to store these data in different shapes and patterns.

Barcodes now have become an important part of people’s lives. They have entered the business world as diverse as transportation and telecommunication. Businessmen find barcodes the most cost-effective aspect pf business and management.

Barcode and scanning system uses several symbols to make the conversion of bar codes into the computer's language making it possible for scanners to read the code. Some most common symbols are code 39 which is now used for data security. This is an efficient way of securing the data as it has the self-checking property that out of 70 million characters scanned, only one error is expected. UPC, another most common symbol is now found on non-food goods sold in the market. This is used for a more efficient and easier price look up without increasing the printing cost. 2of 5 Code was also created for warehouse inventory handling and airline ticketing. Codabar is used to process airway bills and are now very common in freight forwarding companies and custom brokers. Plessey Code is commonly used in grocery stores. This type of code is the one that are put in items and the cashier or teller scans for price look up and computation of the bill and Code 11 is very effective for telecommunication components labeling.

With the development of different symbols for barcodes comes the development of barcode readers or scanners. Barcodes transmit information and the transmission depends on how the bars and spaces in a code are arranged. The barcode scanners are responsible in scanning and reading the information converting it into the binary language then transmitting it to the computer attached to it. Using the light detector attached to the scanner, the amount of reflection is then converted into an analog pattern. Different kinds of readable machines or scanners have been developed to make the scanning more efficient and accurate. These scanners come in a variety of sizes, shapes, and prices. Checkout scanner is the most commonly used. These are found in many supermarkets.  Light pen is also one of the most commonly used as it is portable and cheap. Another type is the barcode slot reader which is used to scan moving codes. This is used in airports to scan the codes attached to the luggage. Laser barcode readers use the laser technology. It deals with light in small powerful beams.  These readers can be used in freight forwarding to track the progress of shipment. It is one of the most expensive scanners and many freight forwarding companies and custom brokers invest on this to ensure an effective and safe transporting of goods from one place to another.

With the latest technology in security and safety, barcodes and scanners are now part of people’s lives. Numerous benefits and advantages are seen with the use of these security and safety devices.
Nowadays, almost all stores such as grocery, department stores and merchandisers use the barcode systems. This is very helpful to track prices without having confusion especially with large purchases. It also helps in making transactions faster and more efficient.

In big offices and companies, document management is a management now being used to manage the hundreds of documents. Several tools used in the management model use sheets with barcodes in separating the documents.
Custom brokers and freight forwarding companies use barcodes to track the shipment and movement of items.
Biological science now makes use of bar coding technology to track reproduction of insects.

Airlines, stadiums, theatres, car rental companies, and other establishments that give tickets have barcodes on the tickets to verify the validity before allowing the guests to enter.

In the recent years, the decline in production of many factories and manufactories has been seen. This was due to less effective, costly and less efficient manual labor. But with the development of barcodes and scanners, this situation was gradually reversed. This is also true for some who encountered problems in their business. Investment is always a part of one’s business. Try to invest for the security and safety of your own business. It’s gearing towards a risk-free path.

Before there was iPod... we have ...

In 1992, Sony introduced the minidisc format as the replacement to linear cassette.  It allowed for recordings from mics, analog, and optical sources.

In 1992 Sony launched the MiniDisc (MD) as an attempt to replace audio cassette technologies. The MiniDisc was developed based on magneto-optical storage media that allowed for writing and rewriting of stored information. The fact that the data could be quickly accessed without the need to scroll through an entire tape made this technology very promising for ease of use over the cassette. The data compression format known as ATRAC (Adaptive Transform Acoustic Coding) was used to allow the audio files to fit on the MiniDisc. In fact, at the SP compression ratio of 292kbps, 60 to 80 minutes of music could be stored on a single disk. Even at CD quality, 20 to 28 minutes of music could be stored on the MiniDisc.

The first MiniDisc based machine was the MZ-1 recorder. The problem with this machine was mainly that it had a cost of more than $750.00. It had an optical line input, audio line input, and microphone input jack. It had an audio output. Some of the earliest versions had an optical line output, but this feature was discontinued. Sony licensed MiniDisc tecnhology to a variety of companies such as Sharp, Panasonic, and Kenwood. It was only a matter of time before all of these companies had released their own lines of MiniDisc players and recorders. MiniDisc players were also developed by Sony for use in the home and car in 1994. All of these efforts yielded no results in North America and Europe, where people seemed content with cassettes for recording and CDs for music purchases. But in East Asia, the MiniDisc took hold and reigned as the top audio format medium through the rest of the 1990s.

In 2000, Sony launched the MiniDisc Long Play (MDLP) format. In the form of LP2, the MiniDisc player could compress audio at 132kbps for up to 80 to 160 minutes per disc. In the LP4 format, the audio could be compressed at 66kbps for up to 320 minutes of audio per disc. But a big difference existed in how the stereo channels were recorded between these two MiniDisc Long Play formats. The LP2 used the same discrete left and right audio channels as the original MiniDisc SP format, while the LP4 began the use of joint stereo encoding.

To keep up with the new MP3 players hitting the market, Sony developed its NetMD for launch in 2002. The NetMD featured a USB connector for exchanging music files with a personal computer. However, in order to use NetMD on your computer, you would have to install their SonicStage (SS) software. Many people found that SonicStage was problematic. In some cases, it froze their computer systems. In other cases it used up a lot of system resources, had file transfer errors, and put restrictions on how often files could be transferred. Though Sony quickly came up with an update called SonicStage CP (SSCP), which was more usable. Their reputation was so tarnished by the original SonicStage that many former NetMD users still won't purchase Sony products.

Other people don't use Sony products anymore because of deceptive claims Sony made about NetMD on the NetMD product boxes and on the Sony NetMD website. Sony claimed the NetMD would be able to play MP3 files. What they didn't bother to mention was that the MP3 files would not be played natively but would have to be re-encoded by SonicStage into ATRAC format during the file transfer process. This not only meant that the sound quality of the MP3 files would be tarnished, but also that file transfers to the NetMD could take several hours.

It didn't help that Sony did not provide good product information to NetMD retailers. All during this time NetMD retailers were telling their customers that files could be transferred from the NetMD to their personal computers. Many people ended up deleting their original files on their computers after transfer only to find out later that they couldn't copy their NetMD files back onto their computers.

In 2004, Sony made a variety of fixes and upgrades to their MiniDisc product line with the release of the Hi-MD. Things such as USB two-way file transfers could now be done.  For the first time, recordings could be uploaded from the recorder to the computer but only files that were recorded in the Hi-MD format.  But for many former MiniDisc customers it was too late, as too much damage had been done to Sony's credibility. In addition to Sony, only Onkyo even bothered to make mini-component systems and home stereos using Hi-MD. But Kenwood, Teac, and Marantz still have MDLP systems on the market, even though Hi-MD is backwards compatible with the previous MiniDisc formats. Hi-MD contains 1 gigabyte of memory and records  in PCM, otherwise known as WAV.

In April 2006, Sony came out with the MZ-RH1 portable Hi-MD recorder. This recorder went the extra step, not only could Hi-MD recordings be uploaded but also recordings made prior to the introduction of Hi-MD could be uploaded.  Without blatantly admitting it, Sony was giving MD users the chance to upload all their MD recordings to computer so the files could be transferred to other formats as the MD-age was now coming to a close.

A whole generation in East Asia has now grown up using the MiniDisc formats. Many people have become hardcore fans. Many people haven't found a viable alternative for making real-time copies of music for replay without requiring the clunky intervention and use of a computer. Many people now collect MiniDisc systems just as a hobby. But the MiniDisc systems live on in popular usage because many people just want to be able to grab whatever they hear to hear again later.

A Tale of VoIP Billing Woe

Beware of hasty decisions, they can come back to haunt you. We should have taken this advice when searching for our voice over internet protocol provider.  Instead we rushed it, and gave ourselves a big headache.

We recently signed up with a Voice Over Internet Protocol provider at work.  At the beginning there was a lot of hesitation to use a technology we thought was considerably young.  Even though in technology age it's pretty old, having been created in the mid 90's.  Still, there were a lot of concerns about reliability and use.  Previously nobody in the office had, had any familiarity with with Voice Over Internet Protocol, which is often shortened to VoIP, and pronounced voyp. 

At the beginning things were frustrating, and we quickly learned that you shouldn't have your VoIP tied to an unreliable internet connection.  Also, we quickly discovered that using our VoIP for faxing was going to be inconvenient.  On top of that we signed up with a service provider who was less than helpful.  One particularly disturbing incident was just recently resolved.  After a couple months with our VoIP we noticed a discrepancy in our bill.  We had signed on for auto-bill pay and when we looked at our bills we noticed that our monthly charges had jumped from the original quote of $39.99, to nearly double.  When I called our provider they explained that when we had signed up they had given us a "free" extra line.  However, after a couple months the offer had expired and the second line was no longer free.  What made the experience even more aggravating was the second line cancellation fee which was something like $40.00.  After talking with the timid operator, who recognized my situation for what it was, a scam, he agreed to drop the cancellation charge.  But we were still out almost $100.00 in charges for that second line. 

This experience left the business with a sour taste in our corporate mouth.  This wasn't so much due to VoIP, but to our VoIP provider.  It was unfortunate that we didn't do the research necessary to find a quality VoIP provider. 

During this whole experience we placed calls to other providers, and we quickly discovered that we had jumped the gun in selecting our voice over IP provider.  These other companies seemed twice as friendly and a far better deal over all.  However, doing this research was like pouring salt into an already gaping wound.

When we had selected our provider, we had merely glanced at the top three VoIP companies out there.  After a brief comparison between companies we made our decision.  Part of the problem was that our decision was made in haste.  This was because we were a start up company and needed a phone number quickly.  Having an operational phone were our customers could reach us was more important than heavy research on voice over IP providers.  On top of that we had to have advertisements made and business cards printed.  So much in business revolves around that phone number and we needed it fast.  That haste decision has cost us an extra $100.00 so far,  plus the additional stress associated with working with a less than hospitable company.

I'm writing this all down so you can avoid the pitfalls that I encountered.  During the time of frustration with our current VoIP provider we discovered that there were lots of smaller companies out there, who offered sometimes more for less than what we are currently paying.  If only we had done a little searching we could have made this discovery and avoided a massive headache.  I've penned this cautionary tale in order to encourage you to seek out these smaller and lesser known providers.

Currently, things have become a little bit better.  But it still hurts to pay our provider every month knowing that there are companies out there who are willing to provide us the same service with a smile.  We would cancel with our current VoIP provider but they have forced us to live in fear.  Fear of having to go through it all again.  Not only would canceling their service come with a charge, but it might also mean we would have to go through the headache all again.  It's the cowards way I know, but it's more convenient then the alternative.

Using voice over internet protocol has been great.  We get our voice messages in emails, and phone calls can be routed to our cell phones if we have to step out.  As far as I'm concerned I wouldn't want anything else in the office.  I only wish I had gone with some other VoIP provider.  The good news is, you still can, and even I can in a year or two.  So do the research and find the right VoIP provider for you.  You won't regret it.

The Basics Of Global Positioning System (GPS)

Image: http://en.wikipedia.org

Below we will learn The basics of GPS. A breif history of how GPS has evolved into a viable market technology. Also a breif explanation of how GPS technology works.

The GPS (Global Positioning System) has been fully functional for nearly two decades. GPS consists of 27 satellites positioned in a medium earth orbit. A satellite is considered to be in medium earth orbit when it is 35,000 kilometers above the Earth's surface, roughly 22,000 miles. The first experimental satellite was launched in 1972. It was not until 1995, 23 years after the launch of the first experimental satellite, that GPS bore fruit as a fully function satellite tracking system.  Even then the system was restricted to military and airline industry use.

Once GPS was fully functional both the military and civilian implications were quickly recognized. In 1996, then President, Bill Clinton, opened the system to civilian uses as well as military uses. Due to limitations early civilian GPS was not very reliable and so its wide spread use had been severely limited. In 1998 and again in 2004 extra civilian signals were added to GPS. The net affect of the added civilian signals was that the quality and accuracy of the data were raised to a level that civilian GPS has now become a marketable product and service. Since 2004 GPS as a market technology has realized a boom in demand with no end in potential growth in site.

How GPS Technology Works

The 27 satellites that are collectively known as the Global Positioning System have flight patterns that make four satellites available to a GPS receiver at any time any where in the world. A GPS receiver must be able to contact and communicate with a minimum of 4 satellites to be able to calculate minimally qualified location data. The larger the number of satellites a GPS receiver can contact the better it will be able to calculate a location.

In order to triangulate a geographic position a GPS receiver calculates the time that it takes for the signal of the GPS satellite to reach the GPS receiver. From this data the GPS unit is able to calculate the distance to each satellite. The time distance information is then used by the mapping software on the GPS receiver unit to determine an exact location on earth.

Satellite signal degradation from both natural and man made obstructions can affect how accurate a GPS unit is. This is why GPS units will try to contact as many GPS satellites as possible. The more satellites the GPS unit is able to contact the more accurate the location.

Uses Of GPS

The purpose of GPS technology has not changed much over the last 30 years. Its primary purpose is still to as precisely as possible pinpoint a location anywhere on Earth. How GPS technology is used has not truly changed either. It is used for two primary functions tracking and navigation.

Growth in GPS technology has not come because of changes in use but because of an increase in signal quality, decrease in component costs of a GPS unit, increase in the quality and sophistication of mapping software, the bundling of GPS units with other services, and more sophisticated marketing to a broader segment of the population.

Today GPS units large and small can be found in airplanes, cars, attached to motorcycles, in cell phones, PDAs and hidden in freight to protect from theft.The shrinking of GPS unit component sizes has enabled the use of GPS to be limited only by your imagination.

The Inner Workings Of the Satellite Phone System

The different ways that communication between two people is achieved with a satellite phone system.  Satellite phones allow communication from anywhere in the world.

In a lot of the very remote places around the world, satellite phones are becoming more and more popular.  Since these phones do not require cabling, the need for communication in these areas has been covered by the use of these satellite phones.  A lot of these remote areas just do not have the infa structure available to allow for a more traditional land line phone.  Radio frequencies could be considered as well but all the frequencies for radio are for the most part, already occupied with other things.

For communication, satellite phones use what is called low earth orbiting satellites or LEO for short.  The main advantage to using these types of satellites over other types such as geo stationary satellites, is that there is very little latency.  Since low earth orbiting satellites are quite a bit closer to the earth, there is less delay in communication.

Each satellite phone system includes a number of LEO satellites usually called a constellation.  The use of many satellites makes sure that there is always a satellite visible to the phone so that calls can be made or received whenever they are needed.  This ensure that there are never any missed calls or calls that get go through to the person that you are calling.

There are a number of different providers that offer these types of phone services - Iridium and Globalstar are just a couple and there are a number more.  Each of these companies use various technologies to get the service done but in the end, they are mainly all the same.  They all provide the satellite communication service.

A few of these companies use a multiple access method of time division to allow and increased number of calls.  This includes connections that are satellite to satellite and the phones work directly with these satellites.  There are also digital technologies that are used to manage the traffic of calls and sometimes this is called, code division multiple access.

When division multiple access is used, the satellites are used to forward the incoming calls directly to the telephone gateways that exist on the earth.  This way, the call eventually goes through the tradtional land telephone network.

With the different ways this satellite phone technology work, the end result does not change.  The basic thing is that in the end, you get through to who ever you need to talk to!

Introduction to Wireless headphones

Wireless headphones is the way to go if you need to use headphones to listen to music when at home. This article is an introduction to wireless headphones and their features as well as their uses.

Everyone who loves music should at some point try to use a wireless set of head phones. Imagine just sitting there in your living room and decide to listen to music, but the kids are sleeping.

Well you have to choice, put your headphones on and sit close to the stereo or make sure you buy a set of wireless head phones and enjoy your favourite music without having to deal with the chord. Even if you are on your computer and you would like to play some music…are you going to carry it around every time you want to go to another room, or for instance relax on your bed? Music lovers world wide are enjoying the perils of wireless headphones for along time now.

Wireless headphones are very beneficial because of a few factors. Lack of cables and tangling. Being literally attached to the source of music is not necessarily a nice thing. A chord does not allow you to move freely. There is always the chance that you even forget about the chord and make a sudden move to get up and bring your computer or stereo with you. It happens; especially of the chord is a short one.

Wireless head phones give you freedom of movement, you can move around in your house, for many feet away from the source without having to worry about any chords or dragging the stereo. You have freedom to move around. It is a benefit that’s goes hand in hand with owning a wireless set of headphones. You can do all those chores, round the house, while enjoying your favourite music; even vacuuming the carpets.

When the vacuum cleaner is on is nearly impossible to hear anything, especially music coming from the stereo. If you have a set of wireless headphones then you can listen to your music while vacuuming. If they are a noise reducing set then you wont be able to hear the vacuum cleaner at all.

You can buy a set of wireless head phones for less than $100. Some are much more expensive. Usually professionals, studio professionals don’t need to use wireless headphones; they us the regular ones. The only music professionals that use wireless headphones are disk jockeys that really need to get rid of those nasty wires that get tangled with their equipment.

Most good quality wireless headphone units have a 150 ft range limit. If you want to enjoy listening to music outside that radius all you need to do is move the base, bring it closer to  the area you will be located. You can even listen to music while gardening or in the garage. As long as you're in range, you will be able to hear your music without and problems whatsoever.

Wireless headphones definitely add convenience to our everyday lifes. If you are in the market of a wireless headphone then take the time and find the one that is right for your needs, the one with the right range, the right features and of course the one in the right price range.

Digital Electronics and Renewable Energy Go Hand In Hand

More and more businesses embrace renewable energy, recycling and reuse in an effort to bring us more efficient, greener and environmentally friendlier digital electronics.

Someone once said "It takes money to make money," and that is mostly true. Today, we might add, "It takes energy to make money," with reference to all the wondrous digital electronics we use every day to conduct business and create things. Problem is that it can take quite a lot of energy to run all the computers, peripherals, big screen display and multimedia installations in our homes and offices. And a bunch more to keep all those cell phones, digital cameras, GPS systems, iPods and handheld gaming systems charged and ready to go. So while the cost of energy keeps rising, and more and more people realize that climate changes, pollution and diminishing oil reserves demand a move towards renewable energy sources, we consume more and more with all of our beloved electronics.

Does that mean that the very progress that brought us the wonderful world of digital electronics is also digging us into a deeper and deeper hole of energy dependence and spiraling monetary and environmental costs? It doesn't have to be that way. Business and the environment do not have to be at odds. There is, in fact, a green electronics movement that seeks to make our beloved electronics more energy efficient and environmentally friendlier. The movement covers the entire spectrum from huge international conglomerates pledging to recycle, reuse and conserve, all the way to electronics being more energy-efficient and either bio-degradable or easier to recycle, thus reducing what is now called "e-waste" from millions of tons of landfill to reused and recycled resources.

Saving energy and recycling makes perfect sense, and it's no surprise that there are now companies devoting themselves to green electronics and energy sustainability. After all, it's good PR and makes economic sense. But it goes farther than that. There are now even companies that sell both digital electronics AND renewable energy products. It's easy to see how a firm belief in renewable energy, conservation and sound energy policies may drive an environmentally conscious business owner to sell items like solar and wind energy products as well as digital electronics made by companies that have realized that business and society are interdependent and thus embraced green technology.

What is "green technology?" It can be products certified for low emissions, products certified to be more energy-efficient (like the Energy Star pledge and standard), or products using solar chargers or other energy saving technologies. It can also mean support of companies that are actively "going green" by increasing recyclable content, removing environmentally harmful substances, using renewable energy in the production cycle, and supporting environmental conservation causes and projects.

Why would companies go green? Because it's not only the right thing to do, but also because it's an increasing competitive advantage to be seen as a green company that cares about the environment. Just like a lot of consumers reject pesticides and insist on organically grown food products, more and more consumers insist on buying green, energy-efficient technology from companies that care. It's good to know that megahits like iPhones and Wii gaming consoles are made by such companies.

What we're seeing here is really an inevitable, accelerating trend towards smarter, greener and more efficient and conscientious consumption. We all must fight waste and embrace clean, sustainable, renewable energy.

10 reasons to go for body dryers

The hair dryer has been a ubiquitous gadget in a woman’s beauty kit for decades. And now we have moved on to more sophisticated gadgets such as body dryers. Body dryers help us to effortlessly dry our whole body after a shower without going through the rigors of toweling. This article talks about the advantages of body dryers and the reasons for their increased popularity.

Technology has made our life more luxurious and comfortable. It has spawned many gadgets without which we can not imagine our lives. Body dryers are one more addition to this long list of gadgets which makes life a little more livable.

what is a body dryer?
A body dryer is a device used for drying the whole body without a towel after a shower or bath. The drying process takes place due to warm air being released by the blower. The body dryer comes with a pre-fixed blower housing along with outlet and inlet openings.

A body dryer is very similar to a hand dryer with the only difference being in size. As compared to a hand dryer, a body dryer is much bigger in size and helps to dry the whole body within just three minutes of operation. To use the body dryer, you simply have to stand underneath the ceiling-mounted unit, switch it on with the remote control and adjust the heating as per your comfort.

You are all set to enjoy the feeling of warm air. Since body dryers come with an adaptable temperature setting, they are perfect for homes with or without an electric shower.

There are quite a few benefits of using body dryers instead of towels to dry your body after a shower. Some of these are:

1. Body dryers help you to dry your body easily after a shower. It takes less effort than using a towel.
2. You don’t have damp, smelly towels hanging around in the bathroom.
3. Body dryers dry your body in a more gentle and relaxing way as compared to towels.
4. When it comes to hygiene, body dryers are a much better option than towels.
5. Body dryers are faster and provide better result than any type of bathroom heater.
6. Body dryers are particularly helpful in drying kids and pets after a bath.
7. If you have difficulty drying yourself with a towel because of mobility issues or skin irritations then a body dryer can provide a more pleasant experience.
8. Not only are they easy to operate, they are also economical.
9. With body dryers you get less laundry work to handle.
10. The best part about body dryers is that they help in reducing the moisture in the bathroom by making it dry quickly.

With so many benefits, body dryers are becoming quite popular in countries like the UK, the USA, Australia and also developing nations.

Electronics Guide: How to Choose a DVD Player

Need to buy a DVD player for yourself or a loved one? DVD players come in many shapes and styles. Use this quick electronics guide to find the
player that's right for you...

Whether buying for yourself or a gift for a loved one, finding just the right DVD player isn't as easy as it seems. There are so many formats, sizes and added features for DVD players today that you might sift
through hundreds of players before finding the right one at the right price. Use this quick guide to compare the types of DVD players available on the electronics market.

DVD Player Sizes 
Determine what size player you will need. If you're adding a DVD player to your home entertainment system, determine where you will put it and how much space is available. Normal-sized DVD players can be rather wide so you'll want to be sure of your available space before shopping. DVD
players are also very thin in height and most have a slot on the front that slides in and out for inserting the DVD. This is great if you have a wide space that is limited in height.

For odd-shaped spaces or very tight spots, there are different sizes and shapes of DVD players. These are usually available at electronics stores online so you'll have plenty of styles to choose from. The vertical DVD
player, for example, sits upright similar to a vertical computer drive. It comes with a stand to hold it in a sturdy position. If you still have your old VHS collection, there are DVD/VHS combo machines that play both
formats. This saves space as well. Also available are super slim DVD players and "space saver" DVD players to fit your personal needs.

Types of DVD Players
Once you determine the size you'll need, you're ready to compare name brands and features at the electronics store or website of your choice. You can often find many different brands and styles of players at one
single electronics mall online. This will allow you to compare without spending hours searching through many websites.
Some of the features you'll see include progressive scan, time-slip recording, EZ editing, zoom, slow motion, HD (high definition) DVD, front audio/video input jacks, CD-R/-RW playback, MP3-CD playback, D/A
converter, favorite scene selection, TV Guardian, and many others. You may not find one particular DVD player that carries every feature, so it's wise to determine which features are important to you before
selecting a player.

Which features will you likely use the most? Which will you probably never use?
You'll also notice there are many brand names for DVD players. Some of the well-known brands include Philips, Coby, Emerson, Toshiba, Magnavox, Sanyo, and Panasonic. Pricing for DVD players can range from around $50 to $500 depending on the features you choose.

If buying a DVD player for your child, there are also players with children's themes. The player will actually look like the child's favorite cartoon character! To find the DVD player that's right for you, search online by brand name, features, or price to compare. Or, you can visit an online mall to compare all in one location.

Besides electronics, you can also find other great items at an online mall such as computers, laptops, lingerie, pets, automotive products, telephones, jewelry, household products, toys, and more. Take your time to find the DVD player that will meet your needs. You'll enjoy years of quality entertainment!
