KR940015979A - Recording format and apparatus for high speed reproduction of video signal and method thereof - Google Patents

Abstract

The present invention relates to a recording format and apparatus for a high speed reproduction of a video signal, and a method thereof, wherein a video signal is a frequency corresponding to a predetermined multiple of a control signal of a predetermined frequency on a control track of a recording medium recorded on a data track in a segmented manner. A recording format in which a double speed control signal for double speed reproduction is recorded, and an apparatus for reproducing a recording medium having such a recording format includes a reproducing amplifier for reproducing a signal recorded on a control track and a signal reproduced by the reproducing amplifier. The data detector for shaping, the counter for counting the waveform-shaped signal in the data detector and counting the cycles of the plurality of tracks M constituting one field, the acceleration time and the number of the speed control signals according to the predetermined speed (N) regeneration mode Memory to store, any field cycle depending on the data stored in the memory and the result of the counter corresponding to the predetermined double speed playback mode The tape speed is changed to correspond to the set speed, including a capstan speed controller that allows the (N-1) * M track to travel at high speeds and normal playback of the M track during periods of other fields. By reproducing only the screen having the interval of, there is an effect that can provide a clear image of high quality.
