HDTV Breakthrough for DBS?
Posted 08 October 2002 - 09:37 AM
Essentially it takes 4 HDTV channels and converts them form fixed bit rate to variable bit rate on the fly. It allows a cable system to put 4 HDTV channels in a single channel (up from the current 2). Since a single DBS transponder (8PSK) is about the same (or more if turbo coded) than a single cable channel (256 QAM), this would allow a DBS operator to put 4 HDTV channels on a single transponder.
This would be a major breakthrough for DBS. If DBS could use a single transponder to send the big 4 (ABC/CBS/NBC/FOX) in HDTV, it could allow the top 20-30 DMAs to be served pretty easily. E* could use 10 transponders from each "wing" sat to hit the top 20 markets. They could even throw in WB/UPN/PBS for the top markets with another transponder.

I'm just not sure what the chances are of them making a change.
Now playing with 2x 622s.

If they have a merger it will help 100x since they would probably replace all the boxes for free.
