Definition: HDMI, short for High Definition Multimedia Interface, is an interface for transmitting uncompressed digital data between devices.
HDMI requires specific cables and connection slots. You'll commonly find HDMI used with HDTVs as a connection between the TV and the source of the HD signal, such as a Blu-ray player or a set-top box.
With some digital cameras, especially those shoot full HD video, an HDMI connector allows you to transfer the video to your computer or HDTV more quickly.
