System on silicon-IC for motion compensated scan rate conversion, picture-in-picture processing, split screen applications and display processing

An IC for consumer electronics TV sets performing 100 Hz interlaced/60 Hz progressive scan rate conversion has been designed. Picture-in-picture, split screen and picture improvement capabilities are also integrated. It applies a motion-compensating algorithm for high-quality scan rate conversion. PIP processing is done using a full frame based scan rate conversion method. Split screen applications with two asynchronous input sources are supported. All field memories are included using a high performance embedded DRAM technology. Therefore the IC, which is compatible with current TV concepts, meets economical demands with increased functionality.
