As far as I can tell the only technology that they have put on an ASIC is SupraFRC, which is their frame-rate conversion technology.
An existing video processor manufacturer could incorporate this technology in conjunction with another ASIC/FPGA that does deinterlacing, scaling, noise reduction, color correction but I think it would be more likely that they would develop their own technology in-house.
