ABSTRACT:
Analog primary color video signals of a still-picture converted to luminance and color difference components and converted to digital samples. The digital samples of each video component are written into a respective memory at the sampling rate and retrieved by a reading circuit at a rate lower than the sampling rate. Analog multi-channel audio signals are converted to digital samples which are time-division multiplexed with the retrieved digital samples of the video components. The multiplexed digital samples are recorded on a recording disc medium in a spiral track pattern.
