HDMI stands for "High Definition Multimedia Interface." It has become the de facto standard for home theater equipment - any new HDTV should have an HDMI input (some have 5 or 6).
The advantage of HDMI is that it carries both your audio and your video in one small cable. It is also a digital interface capable of extremely high bandwidth - the latest commercially-available version (1.3) carries over 10 Gbps.
