Sounds like you're speaking of multiplexing, a method of putting more than one television signal on the same carrier, by switching from one signal to the next (usually up to eight video feeds) in a round robin style. Since the system operates at a very high frequency and the the video is running at a much lower frequency, it's possible to do this without the television receiver, satellite receiver or cable box showing any indication this is taking place. It's most common on satellite transmissions where it's now possible to send up to eight TV separate digital channel feeds in the space it one took to feed just one analog video feed.
