TV out chipsets

Many of the graphic cards sold today are equipped with a TV-out connector to display content on an ordinary television set.

As of August 2005 there are three major manufacturers: Chrontel, Philips and Conexant.

The circuitry involved in the TV out is usually encapsulated in a shielded metal box. The chip set has to convert the graphics information that the video card receives into standard TV signals. These are usually composite video or S-Video, which are significantly different video encoding from computer monitors such as EGA, VGA, or XVGA.
