Abstract
PURPOSE: To perform correct reproduction when sound, still-picture and motion- picture signals are mixed by repeatedly controlling an at least one-frame correspondence part of a recording medium in accordance with still picture information by sequentially scanning the recording medium in accordance with motion-picture information and a sound information decision signal.
CONSTITUTION: In a recording part, a discrimination signal is inserted into a blanking part of a frame and then mixed into a video format signal before being recorded. In a reproduction part, on the other hand, switching unit 14 supplies the video format signal to picture signal processor 15 in accordance with a motion- picture information decision signal or still-picture information decision signal and the video format signal to sound signal processor 17 in accordance with the sound information decision signal. Corresponding to the motion-picture information and sound information decision signal, signal detector 10 scans recording medium 9 in sequence and controller 24 performs the control of a repetitive scan of unit 10 on a part corresponding to at least one frame of recording medium 9 in accordance with the still picture information signal. Consequently, correct reproduction can be attained even if sound, still-picture and motion-picture signals are mixed.
