If you wanted digital audio as well, that would mean a tenth cable. HDMI conveys both video and audio with full resolution and digital precision-all on a single cable! The options for audio are equally rich. For example, the HDMI output of Sony ES Series DVD players can support a full range of digital audio, including 2-channel stereo PCM, Dolby Digital® and DTS® 5.1-channel compressed audio and even uncompressed multi-channel PCM audio! With so many choices for video and audio output, you may wonder whether users will be knowledgeable enough to get the best performance from their systems. Is RGB preferable to Y/Cb/Cr? Is 720p better suited to their television or 1080i? While users will have their choice from a menu of options, HDMI offers a simpler way. Component-to-component communication A system called "product unique key exchange" enables connected equipment to automatically confirm the type of component connected through HDMI. In addition, a source component (such as Sony's DVP-NS9100ES DVD player) can automatically transfer the appropriate audio and video by checking the input capabilities of product next to it (such as an HDMI equipped television or A/V receiver). In this way, the equipment can automatically choose the highest performance audio and video formats that the source and target components both have in common! Consider what happens when you connect an HDMI equipped DVD player to an HDMI equipped television. On first connection the two components exchange basic information-they "introduce themselves."
