A Panasonic HD plasma TV uses two different types of audio-video cables to connect cable television service and a DVD player. To take full advantage of the Panasonic's high-def capabilities, you'll want to connect the set to an HD cable box with an HDMI (high definition media interface) cable. The DVD player connects with a standard set of composite cables to one of the composite AV inputs on the back of the Panasonic.
Connect the HDMI cable from one of the HDMI input ports on the back of the Panasonic to the HDMI out-jack on the back of an HD cable box. The six-edge plug inserts in one direction only, with the narrow end facing down.
