What compression is programing delievered to Dish?

[Paradox-SJ]

I know E* is moving towards MPEG4 but is programing delievered to them in MPEG2 or uncompressed?



Will providers ever switich to MPEG4..is there a need or benifit if they did?

good question, you would think the provider gives it in mpeg4,, E* is only gone switch mpeg4 to hd channel, if they switch all the programming to mpeg4, they will have to replace all of the recievers, and i dont think everyone provides mpeg4.

I don't know about all feeds, but a lot of them are raw feeds fed via fiber optic connections.

DISH gets some programming in analog, most in MPEG2, very little in MPEG4 (Turner is the #1 MPEG4 user so far for distribution feeds to dbs/cable/fios/iptv providers).

I'm sure DISH network does reprocessing of every signal (since the master feeds are much better quality (esp. higher datarate in most cases) than what DISH transmits out by satellite to end users.

Actually that does raise an interesting image quality question. Since MPeG is a lossy compression, are they re-compressing MPeG2 into MPeg4 and thus losing more image quality?
