I think you are over-generalizing, and believe that it's more of an individual case-by-case issue than that. We get TV5 and pixellation is atrocious most of the time. This is relayed by C-band, most likely, and could be as good as they want it to be. It may be that their costs are lower if they use less bandwidth, but whatever the cause, it's clear that the feed (being the first place compression occurs) is a big factor.Originally posted by Mike123abc
Some stations may uplink a bad signal, but that would not really be in their best interest. New cable systems do not have trouble showing high quality pictures on these channels, and they recieve them the same way. It is compression.
Local channels do depend on how dish gets the signal.
