Without a big enough TV and good enough eyes, the difference can easily be beyond discernable. I do side by sides all the time here, because I get the same 1080 satellite feeds that CBS (18GB/hr) and NBC (10GB/hr) affiliates use for broadcasting. The difference is there, but without seeing both at once side by side, it's tough to care about the small difference apparent without a big enough TV.
If your watching the "raw feeds" the image quality will blow you away. "Raw feeds" is the video that comes straight from the source of live programs. This is direct from the satellite uplink to the main production studio. [ you also miss all the commercials ] Once it gets to the main production studio it starts losing quality fast. The video processing equipment adds what is called "compression". Everytime they add something to the image, like the name of the person on screen it adds more "compression" so video quality degrades. NBC and CBS send their feeds at 1080i. ABC [ US ] only does 720i. You can't broadcast "p", way to much bandwidth. The station feeds are cleaner than the signal over the air because the processing equipment at the station adds even more "compression". By the time you get your signal from your local station the video quality has basically gone to crap. One other thing. Local stations can control the amount of bandwidth on any of their channels. Our station in Wichita has eight channels on the air, 43.1 through 43.8, on one transmitter. we allocate bandwidth by "channel" based on what the programing is for that channel. Our best channel, 24/7 movies, has the best bandwidth and the picture quality is "very good". Our next two "best channels", Ebru and Mi Casa, have just slightly less bandwidth and still quite good quality. The others are "good" quality. All are very clear and watchable. On an "average" TV you wouldn't even notice the difference. -- I may be crazy, but crazy is better than stupid. _ _... ..._ _ _._ ._ ..... ._.. ... .._ -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
