That's why you get those pixelations in motion sequences.
If they're going to stream the broadcast at 11000kbps, they should at least bump the resolution down to 720p to reduce the artifacts.
Rev, I hope you're just describing this bit starved situation for what TW Cable itself puts out. When Charter gets a good uplink I get a great picture, and same with what I've seen from DTV and Dish. What I mean is that I'm hoping their production in the field and uplinks to the "bird" for distribution is as good as my benchmark now (usually) of ESPN and ABC, NBC, CBS.
If they suck at that, after this whole stressful period, they should rightfully so get killed and embarrassed on the major forums that cover stations' image quality. Fox was good and so was KCAL.
Yes, I'm describing TWC's stream to my digital cable box.
I don't have access to Charter, DTV, or DISH. All I do know is that DISH and DirecTV utilize MPEG-4 AVC for streaming to end users, which is a superior video codec, so lower bitrates probably don't look nearly as bad as they do for MPEG-2. I'm not aware of what codec Charter uses.
I very much doubt the stream being sent through the satellite is the same one that goes to the digital cable box at home. I believe recompression is being done to save bandwidth.
Wouldn't the type of TV you have play a role in the picture quality as well?
