Digital video signal recording system and reproducing apparatus
First Claim
1. A digital video signal recording system comprising:
- first producing means for independently subjecting a luminance signal and two kinds of color difference signals of a color picture information to be recorded to digital pulse modulation, to produce a digital luminance signal and two kinds of digital color difference signals;
second producing means for dividing said digital luminance signal and said two kinds of digital color difference signals into picture element data groups, in terms of specific number of rows or specific number of columns which are adjacent on a screen, and adding a header signal at least comprising a synchronizing signal, a picture mode identification code, and a picture information quantity identification code to a beginning position of each of said divided picture element groups comprising said digital luminance signal and said two kinds of digital color difference signals, to produce a digital video signal having a signal format in which said digital luminance signal, said two kinds of digital color difference signals, and said header signal are time-sequentially multiplexed; and
recording means for recording said digital video signal onto a recording medium.

Abstract
A digital video signal recording system and reproducing apparatus comprise a circuit for independently subjecting a luminance signal and two kinds of color difference signals of a color picture information to digital pulse modulation, to produce a digital luminance signal and two kinds of digital color difference signals, a circuit for dividing the digital luminance signal and the two kinds of digital color difference signals into picture element data groups, in terms of specific number of rows or columns which are adjacent on a screen, and adding a header signal at least comprising a synchronizing signal, a picture mode identification code, and a picture information quantity identification code to a beginning position of each of the divided picture element data groups comprising the digital luminance signal and the two kinds of digital color difference signals, to produce a digital video signal having a signal format in which the digital luminance, the two kinds of digital color difference signals, and the header signal are time-sequentially multiplexed, a circuit for recording the digital video signal onto a recording medium, a circuit for writing each of the divided picture element data groups picked up and reproduced from the recording medium into a memory circuit according to codes within the header signal, and a circuit for producing an analog video signal in accordance with a standard television system from picture element data read out from the memory circuit.
