ABSTRACT:
An input video signal composed of a luminance signal Y, and color difference signals PR and PB. The video signal is converted into digital signals. A plurality of coding paths are provided. The digital video signals are processed in shuffling circuit, DCT circuit, quantizing circuit, variable length code encoding circuit, and frame segmenting circuit on the coding paths. The signals encoded on the coding paths are converted into data with two channels. The data with two channels are recorded on a recording medium. The data are allocated to a predetermined region of a magnetic tape so that a block of data is reproduced as bursts on a screen in a variable speed reproduction mode.
