In recent years, the development of television in our country has made leaps and bounds with the popularization of small and medium television stations and video relay stations. The source of most of its programs are video tapes, but the current operating system (playback) video playback methods are almost all manual operation. This method of working staff nervous, prone to error, and the use of more switching operation pause button, the tape has some damage. In response to this problem, we piloted in 1985 a recording (playback) camera automatic control player (hereinafter referred to as the player) consisting of electronic calculators and logic circuits, has been operating safely for more than 1000 hours. Features of this player are: (1) Both programs can be reviewed simultaneously at normal speed or fast, with high efficiency.
