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

An IC (available commercially as the SDA9410) for consumer electronics TV sets performing 100 Hz interlaced/60 Hz progressive scan rate conversion has been designed. Picture-in-picture (PIP), split screen and picture improvement capabilities are also integrated. It applies a motion compensating algorithm for high-quality scan rate conversion. The PIP processing is performed using a full frame based scan rate conversion method. Split screen and multi-picture 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.
