HD tv doesn't "work". HDTV is currently (2008) a name for a television standard where the picture is built up by 720 or 1080 lines horizontally.

There are many kinds of HDtv sets. The most used now being LCD-TVs and Plasma TVs. You also have other technologies, such as LCD-projectors, DLP-projectors, back-projecting TVs and OLED-displays. All may be HDtv-compliant, as long as they are able to display 720 or 1080 lines horizontally.

To be HD, the signal also has to be as clear as possible. The best way to do this is via a digital cable, such as HDMI or DVI, but you can also use component cables, where each color is transported separated through each own cable, for instance using shielded component, SCART or the standard D-SUB VGA-cable you know from older PCs.

The way the TV itself works varies from set to set, so please ask "How does LCD monitors work" or "How does a Plasma TV work" instead.
