Virtual Channel Numbers let a station pretend to be on a particular channel number. The actual RF channel number doesn't need to match. But the channel number you key in using your TV remote does need to match the virtual channel number.

If I'm not able to watch my "Creature Double Feature" on the real actual channel 56, I just don't want to live any more.

So does the TV have to scan all RF channels at startup to build a virtual->RF channel map?
