  • Information recording and reproducing apparatus
    Patent number: 5857056
    Abstract: In a recording and reproducing apparatus, a digital luminance signal and digital color difference signals generated from an input video signal. A digital audio signal is generated from an input audio signal. The digital luminance signal, the digital color difference signals, and the digital audio signal are time-base-compressed into a compression-resultant luminance signal, compression-resultant color difference signals, and a compression-resultant audio signal, respectively. The compression-resultant luminance signal, the compression-resultant color difference signals, and the compression-resultant audio signal are multiplexed into a multiplexing-resultant signal on a time-division-multiplexing basis. The multiplexing-resultant signal is recorded on a recording medium. The multiplexing-resultant signal is reproduced from the recording medium.
