FYI:
I maintain two digital transmitters, the local NBC and CBS. If there is a power glitch or
network hickup, the PSIP computer and the Digital Encoder (what takes the digital stream and makes it 8VSP) get out of sync. We have the same units 90% of the stations have and they require a lengthly reset in the correct order to redo. Without that, newer receivers can't get you.
At least, if I see it disappear on DISH, I can get to our equipment remotely and resync them. However, at many stations, there are only one or two people who know how to do this. We have one other, besides myself. The reason is ma€ny people, who might be up for lessons on when fries are done at the local McDonalds, have access to the controls, and there are thousands of items in the menu's. We are password protected, but they've hacked the four-digit passwords before.
