There is one thing I am curious about, maybe you can clear it up. FOX's national feed. I've read it's 480i widescreen and I've read it's 480p widescreen. I know local station send it out in the format of their choice. My local Fox WRAZ-DT 50(49-1) sends it out upconverted to 1080i.
Is the national feed Fox sent to the local stations 480i or 480p?
It is actually a 480i anamorphic. The 16:9 signal is sent in a 4:3 picture and the station "stretches" it back out. The black bars that are on network feeds are generated by the receiver and not from network. So the receiver is always outputing 16:9 no matter what the source AR is. It is a pretty slick system. Film is sent with 3:2 pull down from network and most AR boxes have a way to deal with the 3:2 pull down and when it is sent out at 480p, it looks like 480p which is why the live stuff isn't quite as good as the film stuff.
Also I noticed yesterday that WRAZ-DT has changed their HD channel from 1080i to 720p. I don't know how long that has been like that, but I am sure it is in anticipation of FOX going 720p next year. I think I heard Bob at WCCB say they had also changed from 1080i to 720p, but don't hold me to that one. I just don't remember. My brain is a little mushy right now.
After the manufacturer alerted me to a potential problem this morning and finding ONE programming mistake in our HD encoder related to that problem (which I wasn't experiencing), I just had to dump all the settings and completely reprogram it from scratch from the front panel without the aid of a programming software. That took about an hour, but it now (I hope) meets the manufacturers spec.
Guess I will finish my lunch now and go down to the transmitter.
Just another day in paradise!
