Abstract
Abstract A television editing system includes devices which respond to the absence of picture information in a video signal for at least a predetermined period of time, a prelude to the start of a commercial message, and disable or reduce the audio output from a television set or the like for a given period. A microphone is arranged to receive an external audio recall signal, which could be produced by a user clapping his hands. This received signal is processed and used to recall the audio output within the given period. A circuit, responsive to received video signals over a period during which several commercial messages may appear, automatically sets the sensitivity of the editing system.
