Does anyone know if the delay was a local decision by WUNG (UNC TV), or PBS policy. Either way, it sure seemed weird and begs the question, why?
as far as I know, there is no local decisions made at any of the UNC transmitter sites. All the UNC stations are on the same network. Part of the time disparities come from the need to acquire and retransmit the programs. There are time factors in sending from a location (such as Charlotte) to a network head, then through the network to the stations, which then has to acquire and transmit. In the case of the UNC network, there is at least an extra step in going through its own network.. Every once in a while, I'll cut on one TV before cutting off another, and if they are receiving the same program on different stations, same network, there will be a noticeable difference in when the sound and picture display. In the digital world, with untold numbers of buffers, there can be a BIG difference in when a "live" program is received. It is an antiquated notion that TV signals travel at the speed of light.. Electrons mat travel that fast, but today they hit a lot of speed bumps and stop lights these days.. Its possible that PBS was using an intentional time delay, also. I don't know about that.
