Increased with the arrival of the HDMI which means high definition Multimedia Interface, the options for the management of the transmission of content high definition digital televisions and connected devices. Launched in December 2002, the HDMI 1.0 was the first commercial version of HDMI. In May 2004, HDMI 1.1 was introduced. This filled a gap and added audio DVDs to the other content which has been already supported. HDMI share many characteristics similar to Digital Visual Interface (DVI). While the physical interface is different, the actual content of transmission is identical except that DVI does not audio.

Hitachi, Sony, Philips and other developed partners HDMI 1.0 had a clear purpose to pass the DVI version then in force in 2002, called DVI-HDCP and DVI-HDCP. HDMI offers immediate benefits, including a smaller connector and adding audio support. Perhaps the addition of this feature that in fact such a big hit against the DVI competitor. The addition of support YcbCr is a considerable advantage also. Consumers have long soft to have a remote control hand for each separate device, one for the TV, one for the video recorder and the other for DVD player and so on. A single remote control can now control all audio video devices. Not only what it means that several batteries could be saved, but also the necessary user only to learn how to use a handheld computer and simply flick on the device they wanted control.

For example, a device audio visual was developed in a manner that was backward compatible. It was extremely important. Similarly, asking consumers to audio visual products which work perfectly well - simply because the connector is wrong - does not sense. A converter simple cable is able to operate the whole, without conversion or complex equipment boxes are required. Perhaps it was this factor that allowed the passage HDMI to be so transparent.

It was estimated by the manufacturers that allows testing centres will have to be put in place and it was a sensible decision. Without ATC, or authorized test centres, there is always the risk that manufacturers of products on the market that deviate slightly from the HDMI standard. If they are launched on the market, this can cause problems for users. The first ATC was opened in June 2003 by Silicon Image, shortly before the launch of the HDMI 1.1 to the Japan by Panasonic. Now have the operational ATCs was a very important step for the HDMI industry, it would now be possible to develop and encourage additional providers to join the HDMI community.
