It's useful also for broadcasters who want to transmit more multicasts, or to reduce the artifacts in the multicasts they transmit now. I know WETA-DT, with its 4 multicasts, including one HD, could make use of such a product. It would be fun to see a comparison of this against H.264. In essence, what this Algolith product does is a clever pre-filtering, before MPEG-2 encoding, as opposed to the more meat axe approach to prefiltering you might see now. Makes sense. Since the H.262 encoder is well understood, it should be possible to use digital filtering techniques before it, to prevent the H.262 encoder from becoming overwhelmed. With a digital pre-filter that knows what specific aspects of the given video will overwhelm H.262, image pre-filtering should be possible with reduced image degradation. > It's hard to imagine consumers putting such a processor on > their TVs. But it's not so hard to believe that the manufacturers of especially large TVs would build this, or similar, into their products.
