Thought I was posting this in the "Cincinnati" thread, so will do so now. Thanks Jeff (Nitewatchman) for the response. Have posted your response at the end of my thread -
Hello folks - new owner of a HLN5065 tv, and as I recall standing in the chekcout line thinking I must be some kind of idiot to drop $4k on a TV, everytime I turn that thing on, I am amazed at the picture I see. Thank God for 2 years, same as cash.
Anyway, I'm trying to understand why a football game I watch in HD on CBS on the WKRC feed has, what I think is called "compression artifacts", galore..and the MNF game I watch on ABC is an absolutely stunning picture.
Is it the fact that the CBS game is transmitted in 1080i format, and the MNF game is in 720p, and there is just that much difference in PQ between these 2 formats? Or does it have something to do with not enough bandwidth being allocated by WKRC to the CBS Sunday football game, and the ABC station is providing ample b/w for a quality HD picture on the MNF game. Still a newbie on this HD stuff and trying to determine why the CBS pq is really poor vs. the MNF pq - thanks all -
WKRC-DT(1080i CBS HD) is allocating 15mb/s to CBS HD instead of the full amount possible, according to one of their engineers. I believe they use the rest of their digital stations' bandwidth for Datacasting, specifically the "Webhopper" internet acceleration service. This is likely why compression artifacts are a problem for them during demanding HD source material such as NFL football, those of us who have seen the Columbus CBS HD station, which gives all their available bandwidth to HD have noticed that Compression artifacts aren't a problem from the Columbus station.
Oh, BTW, you should be seeing the same quality via TWC as we OTA viewers see.
Concerning WCPO-DT, they multicast a SD weather subchannel, but since they are doing 720p HD, their HD can get by with a little less bandwidth.
