The High-Definition Multimedia Interface (HDMI) is an all-digital audio/video interface capable of transmitting uncompressed streams. HDMI provides an interface between any compatible digital audio/video source, such as a set-top box, a DVD player, a PC, a video game system, or an AV receiver and a compatible digital audio and/or video monitor, such as a digital television (DTV).
It is a modern replacement for older analogue standards such as SCART or the RCA connector.
HDMI supports any TV or PC video format, including standard, enhanced, or high-definition video, plus multi-channel digital audio on a single cable. It is independent of the various DTV standards such as ATSC, and DVB (-T,-S,-C), as these are encapsulations of the MPEG data streams, which are passed off to a decoder, and output as uncompressed video data on HDMI. HDMI encodes the video data into TMDS for transmission digitally over HDMI. Previously, the maximum pixel rate of the interface was 165Mpixels/second, sufficient for supporting 1080p at 60Hz or UXGA (1600x1200), but HDMI 1.3 increased that to 340Mpixels/second, providing support beyond the highest resolution computer monitors available today.
