A lot of posters also just say ABC, CBS, etc., when they are really talking about their local affiliate. Unfortunately, with this medium, we don't necessarily know that, so it has to pointed out. The networks can screw up. It has happened.
Yep, there it was. An actual toggle switch that an actually person had to actually flip when the HD feed came through. No flip, no HD. That simple. It explained a lot.
That is a cheap station. The ones that do it right have it set up so that when master control switches to net, it routes the network SD analog to the analog transmitter and the network HD digital to the digital transmitter. Yes, they have an override, since no network affiliate in my city has the ability to put weather warnings directly onto the HD video (the PBS affiliate can and does). Since Fox uses the splicer system, all affiliates have auto switching (with manual override). As far as I can tell, all of the local affiliates have auto switching. That said, the local NBC affiliate will do their own upconvert for network SD programming, so sometimes master control does forget to turn off the override. I asked why and was told that sometimes the NBC HD feed doesn't have upconverted SD programming.
