Right. That's what they do now. Gotta keep that "channel branding". The offical plan for 1st and 2nd round designations is here: http://hraunfoss.fcc.gov/edocs_public/attachmatch/DA-06-1082A2.pdf In the Washington DC area, WRC-TV moved has analog on 4 and digital on 48 and are going to stay at 48 (a loser move as far as propagation goes, due to free space path loss). WJLA-TV moved has analog on 7 and digital on 39 and are moving their digital channel back down to 7. I'll have to rescan my channels on my digital TV's then. (Most consumers may think that digital "channel 7" turned off if they had it programmed pre-cutover.) What's really fun is that, sometimes, when I do a channel scan and the signal is weak, a TV or STB doesn't get the PSIP info correctly and I get a bogus duplicate. On my Sony TV right now I have a channel 50.1 and a channel 53.1 that are the same digital broadcast. Analog channel 50 has DTV on analog channel 53 with PSIP info saying it's "channel 50". One time my TV got the PSIP data correctly and one time it didn't. What a mess...
