Even mpeg-4 asp (ie. XviD & DivX) would be able to reduce the bitrate significantly over mpeg-2 without losing quality. It would probably be easier and cheaper to implement over AVC (h.264). |

From the article, the new compression scheme "will work with the MSO's massive base of MPEG-2 set-tops". So can it be MPEG4? Or is it variable bit rate encoding or something? |

| I can only imagine it would be really creative variable bit rate statistical multiplexing.
They can put the real expensive high end loop encoder systems in the headend that do all the heavy lifting, while the stb's out in the field act as the dumb client.
It can't be too complicated to decode because the horsepower in the Motorola STB's are practically zilch. Have you ever used one of those DVR's? Try scrolling or changing channels too fast, the dang thing freezes up for 20 seconds and then it plays catch up with itself. |

Utica, MI | Yes, I have a DVR, and it freezes all the time... I don't know if its terrible programming or like you say a very limited hardware set. |
