I've used the TVP7002 on the front end of an FPGA which implemented a triple frame buffer with clipping and scaling engines. In short, the hardware is ideal for collectors of a wide range of retro computing equipment. Having said that, the TVP7002 still required tweaking for different video sources, as did the clipper and scaler. The hardware itself was designed to handle dozens of different video sources and resolutions, and the controlling software was configured to keep track of the tweak factors. So whilst it was certainly capable of handling pretty much every known video source, it was far from a plug and play solution. Once configured though, it was a nice piece of kit. It was also a very expensive piece of proprietary equipment, and I do not retain the rights to the IP, unfortunately. I still have a few boxes that I've used on the Amiga and TRS-80 Coco 3, and did toy with the idea of producing my own hardware based on the same design, but it would be very expensive.
