Abstract
Recording and playback systems for a VCR. The VCR recording system comprises first and second signal input circuits for inputting first and second channel signals and detecting video and audio signals from the first and second channel signals, respectively, a video signal processing circuit for inputting, in turn, the video signals from the input circuits in the unit of one field per one frame and processing the inputted video signals to be recordable, an audio signal processing circuit, and a recording mechanism for recording the first and second channel audio and video signals on a VCR tape, respectively. The VCR playback system comprises a playback mechanism for playing back first and second channel video signals recorded, in turn, in the unit of one field per one frame, on a VCR tape and for playing back first and second channel audio signals recorded, respectively, on the VCR tape, respectively, a video signal processing circuit for processing one of the video signals of the first and second channels from the playback mechanism to be displayable, an audio signal processing circuit, a video signal correcting circuit for correcting the video signal from the video processing circ…
