Chip-set for video display of multimedia information

We present a chip-set for digital video processing in a consumer television receiver or set-top box. Key aspects of the chip-set are a high flexibility and programmability of multi-window features with multiple Teletext (TXT) pages, Internet pages and video processing up to three live windows. The chip-set contains a microcontroller with peripherals featuring a.o. pixel-based graphics (GFX) and telecommunication interfaces. The second chip is a video processor containing a number of flexible coprocessors for horizontal and vertical scaling, sharpness enhancement, adaptive temporal noise reduction, blending of graphics, mixing of multiple video streams, and 100 Hz up-conversion.
