An HDTV can be connected to a cable box using an HDMI cable or component cables. An HDMI cable combines audio and video in a single cable, while component cables are constructed of three video cables [red, green and blue] and require separate RCA cables for audio. An HDMI cable box can also be connected to a HDTV using standard RCA cables or an S-Video cable, although the video will not be displayed in high definition.
