摘要：
The development of a personal computer (PC)-controlled multiple window display card for television is described in this paper. A digital encoder card to convert the red, green and blue (RGB) signals from the PC to a composite video signal (CVBS) is designed and developed. This digital encoder card accepts the RGB analog signals from;the computer VGA display adaptor card and converts them into a PAL or NTSC format composite video signal. A chroma keying circuitry, to enable an additional video signal to be displayed with the encoded CVBS signal on a television screen in a picture-in-picture format.
