HDMI is a fully digital audio/video interface that transmits uncompressed encrypted streams.

HDMI is used to connect an audio/video source (DVD

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.

HDMI : important

HDMI uses a standardized process that organizes video data streams : TMDS .
When the HDMI standard was created, the maximum speed and transmission speed were set at 165 Mpixel/s. This tau was high enough to provide video resolution up to 1080p to 60 Hz. Improved standard has resulted in transmission compatibility of up to 340 Mpixel/s.

Version 1.3 also allows a 10~bit video~per~color transfer, offering a wider range of colors.
This revision adds support for 48~bit color depth.

The video transfer tau ranges from 25 MHz, 340 MHz (Type A, 1.3 standard) to 680 MHz (Type B).
Video formats with rates below 25 MHz are widely used due to pixel repetition.
The refreshment tau can reach 120 Hz.
