HDMI is a type of digital connection that's capable of transmitting high-definition video and high-resolution audio over a single cable. HDMI is typically used to connect a high-definition device--such as an HD DVR--to an HDTV. To make the connection, you simply put one end of the cable into the HDTV's HDMI input slot and the other end into the device's HDMI output slot. And that's it--just one cable and you're all set for the high-definition experience. If you have an AV receiver, just put it in the middle of the signal chain. The output of the AV receiver goes to the HDTV and you connect your high-definition device(s) to the AV receiver's input.
HDMI can deliver the best image quality of any of the cable types available today. It can handle high-definition video of up to 1080p resolution at 60 frames per second, which is the most bandwidth-intensive video format currently available. The older PC-based DVI connection offers equivalent quality, but it is rarely available on HDTVs or video components these days.
