ABSTRACT:
A digital video signal reproducing apparatus comprises a reproducing circuit for reproducing a digital video signal from a recording medium, which digital video signal is added with at least a write-in specifying code and a read-out specifying code for specifying a memory circuit part to picture element data groups which are obtained by subjecting a video signal to a digital pulse modulation, a detecting circuit for detecting the write-in specifying code and the read-out specifying code within a reproduced digital video signal from the reproducing circuit, a generator for generating various synchronizing signals and reference signals, first and second memory circuit parts each having a memory capacity for storing picture element data corresponding to one picture, a write controller for causing the picture element data to be written into one of the first and second memory circuit parts according to a value of the write-in specifying code, a latch circuit for latching the read-out specifying code by a vertical synchronizing signal generated from the generator, a read controller for causing stored picture element data to be successively read out from one of the first and second memory circuit parts according to a value of the read-out specifying code from the latch circuit, and a circuit for converting the picture element data read out from the first and second memory circuit parts to an analog video signal.
