  • Apparatus for recording audio signals and video signals on a recording medium
    Patent number: 5027222
    Abstract: In an audio and video recording apparatus, a video signal is separated into a luminance signal and a chrominance signal. The luminance signal is separated into low frequency and high frequency components. The high frequency component signal is subjected to balanced modulation to be thereafter band-compressed by interleaving the lower side band thereof to the low frequency component. The chrominance signal is processed to be a line sequential color difference signal. An audio signal is sampled and encoded. The luminance signal, the color difference signal and the audio signal are subjected to time-axis compression multiplexing in one frame with a synchronizing signal, address signals and control signals. The multiplex signal is recorded on a recording medium.
