HDMI

PC Interfaces 101
By

Digital multimedia interface for uncompressed HDTV signals up to 1920x1080 interlaced (aka 1080i), with integrated Digital Rights Management (DRM) copy protection mechanisms. The current technology in use today is a Type A connector with 19 pins.

There are no consumer products available today that use the 29-pin Type B connector (which handles resolutions higher than 1080i). The video signal for HDMI uses the same digital TDMS signaling technology that DVI-D also uses. This explains why HDMI-DVI adapters are also available for high-end video gear. In addition, HDMI can also deliver up 8 audio channels using 24-bit signals and 192 kHz sample rates. Note that HDMI cables shouldn't exceed 50 feet (15 m) in length.
