Abstract :
A video display processing system has been developed which offers many advantages compared to analog or conventional digital systems. Its system architecture opens digital video processing towards multi-standard and multi-media applications. An advanced CMOS technology allows economic integration of high-quality TV processing on a single chip. Analog video is input to the color decoder module. It performs analog-to-digital conversion followed by all digital multi-standard demodulation and filtering. Output is YUV and synchronized in an orthogonal sampling pattern. In the display processor the processing from YUV to RGB and the digital-to-analog conversion takes place. Both horizontal and vertical deflection signals are provided. A very flexible high-quality interface supports many features and keeps the system open for TV evolution towards new standards (enhanced-definition TV with a ratio of sixteen to nine) or other displays (100 Hz, proscan, or liquid crystal)
