Chip-set for video display of multimedia information
This paper presents a chip-set for digital video processing in a consumer television receiver. A key aspect of the chip-set is a high flexibility and programmability of multi-window features with multiple teletext pages, Internet pages and up to three live video windows. The chip-set consists of a microcontroller featuring pixel-based graphics, and a video processor containing a number of flexible co-processors for horizontal and vertical scaling, sharpness enhancement, adaptive temporal noise reduction, blending of graphics, mixing of multiple video streams and 100 Hz up-conversion.
