Isn't there some kind of coded information in video frames called VITS? I don't know much about it, but I was wondering if it would be possible to decode that information and detect TV commercials with it. Any comments, stories, or information would be appreciated. -- Robert J. Kelley Mentor Graphics Corporation ...!tektronix!sequent!mntgfx!bobk or bobk@mntgfx.MENTOR.COM

Ya.

As far as I know, the vertical interval doesn't contain any information
anywhere that tells you this is a commercial. Wouldn't that be nice!
But, you can normally tell when the local station is on line because the
time-date stamp line is missing (it is produced by all the networks).
