ABSTRACT:
A digital video signal reproducing apparatus comprises a reproducing circuit for reproducing a digital video signal from a recording medium, where the recording medium is time-sequentially recorded with the digital video signal having a signal format in which a header signal is added to each of divided picture element data groups which are obtained by dividing a picture element data group in terms of a predetermined unit, the picture element data group is obtained by subjecting an analog video signal to a digital pulse modulation at a sampling frequency such that a product of a number of picture element data in one scanning line and an effective number of scanning lines in one picture of a standard television system is exceedingly close to 2.sup.18 but less than 2.sup.18, and the header signal at least comprises a synchronizing signal and a picture mode identification code, a header signal reproducing circuit for discriminating the header signal within the digital video signal reproduced by the reproducing circuit and reproducing the header signal, two memory circuits into which the picture element data group within said reproduced digital video signal is written and from which a stored picture element data group is read out, a circuit for controlling write-in and read-out with respect to the two memory circuits according to a code in the reproduced header signal, and a circuit for producing an analog video signal in accordance with a standard television system from the picture element data read out from the two memory circuits.
