Since the first commercial release of the HDMI consumer products, the popularity of this interface continues to evolve and grow. The High-Definition Multimedia Interface or HDMI for short carries digital audio and video and delivers excellent quality signal, and the HDMI cables could replace a number of older cables and make a home theater or any other setup more elegant and less messy. At the time of this writing, more than 800 of the top consumer electronic device manufacturers have adopted the technology and if you purchase a top of the range TV, gaming console, DVD players, or Blue-ray player, there is a good chance that they would be HDMI ready. Even some of the latest digital cameras and camcorders support the technology and come with a mini-HDMI cable in the box, which cable allows you to connect them to a TV screen, video projector, or computer screen and view your photos and videos instantly.
While in most cases, a home theater setup would require only one cable, there are times when you might need an HDMI switch, repeater, or splitter. An HDMI switch allows you to connect a number of sources to a single TV, computer screen, or video projector, while the splitter ode the opposite; the repeaters are used when you need a longer cable and minimize the signal quality loss. If you are looking for a HDMI switch, then you are likely to find a number of different types, where the 3x1 and 5x1 are the ones that most electronic stores stock. These crafty devices are surprisingly cheap, you could easily find one for around ten pounds and of course, there are better and more expensive models as well. Deepening on the make of the HDMI switch, it could come with a number of additional features such as an intelligent function, which detects when the power of the source goes on and responds automatically. Many of these devices also come with a number of different accessories, the most useful of which is perhaps the remote control that allows you to switch from one source to another with the click of a button.
Keep in mind that many of the newer TV sets come with more than one HDMI inputs, so you might not need a switch at all, but if you wish to connect your HD DVD player and say a gaming console to a TV with one input, then a switch could prove very useful.
