The Teranex people say they do a full-exhaustive search of every pixel to do their motion compensation: I assume this means they compare every pixel with every pixel in the next field to determine the motion vectors, which seems like it should yield good results, albeit at a very high cost. Figuring that the big Teranexen cost about $80K, and the cost of computing power comes down 10x every 5 years, I came up with my WAG of 5 years before we get a consumer box that can do something comparable.
More WAGing: if Josh says they're killing giants, and giants are companies like Teranex, then maybe we'll get something cool sooner.
Thanks for the info on Dale.
