I've noticed that the PQ on TV5 (and the audio, by the way) has always been mediocre. I don't know whether it's the TV5 feed or whether E* and TV5 have negotiated low-bit-rate carriage, but it's noticeably worse than almost all other channels.
Now, I watch TV5 for the content, not the PQ (obviously), but it has made me wonder a bit about some of the technical aspects of DBS. Do some providers send pre-encoded MPEG-2 content to E*? That could explain some of the poor PQ. It would also explain why TV5's PQ is identical on Comcast and E* (I even compared them side-by-side once, and they had identical artifacts).
On the other hand, I suspect that some providers may deliver their signal to E* over a C-band analog link, because their video has telltale C-band style noise on an otherwise very good signal (occasional "tics" visible as white flecks). No doubt there are other ways of getting the signal there, too.
Anyone have a pointer to more info on this?
Thanks a lot.
