HDMI supports standard, enhanced, or high-definition video, plus multi-channel digital audio on a single cable. It transmits all ATSC HDTV standards and supports 8-channel, 192kHz, uncompressed digital audio and all currently-available compressed formats (such as Dolby Digital and DTS).
HDMI v1.3 adds additional support for lossless digital audio formats with bandwidth to spare to accommodate future enhancements and requirements.
