Abstract
A digital signal recording system and a reproducing apparatus for reproducing signals recorded according to this recording system comprise a circuit for alternately transmitting a first digital luminance signal and a first two kinds of digital color difference signals obtained by subjecting a color picture information signal to digital pulse modulation, in terms of information of one or a plurality of scanning lines, and producing a first digital video signal having a signal format wherein signal components of two sampling points of the first digital luminance signal are arranged within the same word and signal components of the same sampling point on a picture of the first two kinds of digital color difference signals are arranged within the same word; a circuit for time-sequentially multiplexing the first digital video signal and the digital audio signals obtained by subjecting audio information signal to be recorded to digital pulse modulation, in terms of words, and recording the time-sequentially multiplexed signal onto the same one track on a recording medium; a decoder for demodulating and reproducing analog audio signals from a signal picked up and reproduced from the recording medium; and a circuit for producing an analog video signal in accordance with a standard television system, from the output first digital video signal of the decoder.
