HDMI
HDMI is used to connect an audio/video source (DVD player, Blu-ray player, computer or game console) to a high-definition TV.
HDMI supports all video formats, including standard, improved, high-definition definition and multichannel sound.
HDMI encapsulanses video data by TMDS.
Initially, the maximum HDMI transmission tau was 165 Mpixel/s, which allowed the standard 1080p resolution to be transmitted to 60 Hz or UXGA (1600 x 1200).
But THE HDMI 1.3 standard has increased the transmission to 340 Mpixel/s.
HDMI also transmits sound up to 8 uncompressed channels on a 192 KHz sampling tau with 24 bit/sample streams and compressed audio such as DTS and 'Dolby Digital surround'.
This data is also encapsulated in the TMDS transmission standard.
HDMI Type 1.3 adds support for very high-quality audio streams - (Lossless) - such as Dolby, TrueHD and DTS-HD Master Audio.
The standard Type A HDMI connector has 19 pins, and a version of the connector that allows for higher resolution called a Type B connector has also been defined : the 29-pin Type B connector to support very high resolutions.
