Video signal identifier for controlling a VCR and television based on the occurrence of commercials

摘要

A video signal identifier ("VSI") electrically coupled to both a VCR and a television to control their operation. The VSI memorizes commercials then automatically controls the television and video cassette recorder upon identifying a re-occurrence of the commercial. The VSI automatically mutes then restores volume on a television or pauses then resumes VCR recording at the beginning and end of a commercial.
