However, in their infinite wisdom the FCC has made it MANDATORY that stations identify themselves in the PSIP (what you see on your digital tuner) with their ANALOG channel number. I'm Chief Engineer for a network of eleven stations and we have two that have the analog and digital transmitters on different bands...i.e. analog on UHF and digital on VHF. Thus, there is a huge amount of confusion when someone see's digital channel 29 on their tuner, when the actual RF is on channel 9 and they don't have the proper antenna for reliable reception. It's gets even crazier when the analog transmitters are turned off in February 2009...the digital stations will be branding themselves with a channel number that is completely unrelated to reality. Then, believe it or not, it gets EVEN nuttier after a few years and another station wants to come on the air and request your old vacated analog channel. They will have to identify themselves as your actual digital channel number...completely unrelated to their actual digital RF channel. Really smart of the FCC, eh?

They have spent years telling you to tune to Channel 4 or what ever. The computer in your television set reading the digital code from the stations will take the channel 4 information and translate it to the correct UHF channel such as in Tucson Channel 23. This special code is called the PSIP code and contains other information such as program playing and a TV guide for that channel. Also a lot other info. It also tells the set if there is more than one program stream such as 4-2 might be weather, 4-3 traffic cam etc. Current equipment will allow up to 4 std def channels in one Hi Def space.
