| Harry Bartholomew was telling me a year or so ago about some ideas for | detecting volume changes. I think, however, the problem of distinguishing | commercial from non-commercial signal is, I think, a tough one. Yes, but the tv stations put in a short period of black & silence before returning to the show. I'm pretty confident that this is what the 'zip through commercials' vcrs cue on.
