  • Patent number: 4390904
    Abstract: In order to delete commercial messages during the viewing and/or video tape recording of broadcast television signals a control circuit is disclosed for producing a commercial editing control signal at the beginning of one or more television commercial messages, which signal continues for the duration of such messages and terminates after the end of the last of such messages. The control circuit incorporates detection circuitry for automatically detecting each of a series of fade breaks in the video and audio components of the television signal, wherein such fade breaks normally mark the beginning and end of each of one or more commercial messages that have been inserted in the program content. The first of a series of detected fade breaks marks the beginning of a single commercial or the first commercial in a consecutive block of commercials, and succeeding fade breaks occur at time intervals that correspond to the durations of the commercial messages.
