[rec.video] VITS Information Requested

bobk@mntgfx.MENTOR.COM (Bob Kelley) (09/04/87)

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.

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).
