Is up-converting the signal the same thing as improving it? Or just manipulating it with no improvement?
If you ever closely examined 720p converted to 1080i, you'd already know the answer to that question!
Indeed the Belo stations with 720p sources do exactly this. Local programming looks good. Network programming, such as movies and other entertainment, is acceptable. Sports is pure crap...at least at KVUE.
When the whole HD thing was shaking out, I had a good friend who was a honcho engineer at the local Fox O&O. He told me that Murdoch's original plan for the Fox stations was to do NO HD WHATSOEVER. The plan was to take that nice 6 mhz bandwidth and multicast four or five streams on each frequency. That was shelved when Rupert was read the riot act by certain members of Congress and the FCC who informed him that the big, beautiful 6 mhz channel was for HD, with the occasional sub channel, and that if he refused to do HD, the Fox stations would not be awarded that much bandwidth.
That's when Fox signed on with 720p. The reason....since day one, we've heard that 720p is better for sports (fast action such as NFL and NASCAR), 1080i is better for movies and lower action video (such as news).
There is no 1080p OTA broadcasting and will never be, IMHO. The equipment that would have to be replaced would cost too much to be justified by the corporations that run broadcasting in this country. They think the increased PQ...even with new compression techniques that may be coming...isn't worth the expense. And with a nation of viewers who don't know the difference between 720p and 1080i, or even what those specifications really mean
, who's to argue with that?
And let me recommend the article in Coolman's link....very good info.
