1. A recording and reproducing system for a digital video tape recorder comprising:

  • first analog/digital signals converter for converting composite image analog signals into digital component signals;

    luminance/color signal separator which separates digital signals generated from said first analog/digital signal converter into luminance signals and color signals;

    first and second image data compressors for condensing transmission amounts of both luminance signals and color signals generated from said luminance/color signal separator at the respective rates;

    first and second means for processing stereo aural signals and the transmitted luminance and color signals thus generating composite signals to be recorded on a same track of a video tape, said first and second processing means being connected to said first and second data compressors respectively;

    means for applying the composite signal to a rotating head drum for recordation on a video tape;

    means for reproducing the recorded stereo aural and image luminance and color signals from said video tape and converting the reproduced signals into electrical signals;

    means for separating the aural signals from the image luminance and color signals;

    first and second image data decompressors for extending transmission quantities of the luminance and color image signals at predetermined rates; and

    a luminance/color synthesizer for combining luminance and color signals generated from said first and second data decompressors.
