If you have used HDTV, PlayStation 3, an HD DVD or Blu-ray player, you have embraced the HDMI technology. The HDMI or High Definition Multimedia Interface creates high-bandwidth connections among digital devices. Your home theatre system’s performance can be greatly enhanced, as current HDMI standards carry up to 1080p high-definition signals and up to eight channels of uncompressed audio, great for 7.1 surround sound. Further, HDMI uses a single cable for connecting components, and also a single remote control is generally sufficient.
HDMI was founded by the top brass of consumer electronics including Hitachi, Panasonic, Philips, Sony, Thomson, Toshiba and Silicon image. Big-shot motion picture producers like Fox, Universal, Warner Bros and Disney were also involved. Major system operators like DirecTV, EchoStar and CableLabs also offer their support to HDMI.
The HDMI technology has several advantages. It provides uncompromised video quality, as it is a digital interface and hence no quality loss due to analogue to digital conversions. The resulting video will be sharper, and without the softness and ghosting around the images. HDMI also ensures easy to use operations, as it combines video and multi-channel audio using a single cable, thus no confusion as against multiple cables used by standard A/V systems. HDMI, in fact, uses one cable to replace 11 analogue cables.
HDMI also has a two-way communication between a video source, say a DVD player, or a PlayStation console and the HDTV, thus the best settings are automatically configured without having to manually scroll through various options to choose the right format. HDMI is also fully backward compatible with Personal Computers. If you have just one HDMI plug on your TV, you can get extra ports, but you can also opt for a system with multiple plugs.
Ever since the first HDMI products entered the consumer market in 2003, there have been a number of additions and developments. Beginning with additional support for DVD Audio, the latest HDMI 1.3 is packed with features like increased bandwidth, 16-bit colour support and also support for additional colours through the xvYCC colour standard. There is also a lip-sync features that reduces the video and audio going out of sync during playback.
Offering true HD experience, true sound experience, and absolute convenience, HDMI allows home entertainment in the best possible way.
