Abstract

PURPOSE: To cause the phase of reproducing data signals and the phase of error decision signals to agree with each other practically by combining a First in first out memory (FIO) and an RAM to constitute a memory of the reproducing part.
CONSTITUTION: PCM signals such as video of one horizontal period which passed through series-parallel converter 31 are written in FIO32 by write command 37, and simultaneously, gate 38 is closed and read command 39 is not applied to FIO 32. Meanwhile, a correct or error signal according to decision of a CRC signal, etc., which is added for every prescribed number of samples of PCM signals dependently upon error detector 33, is written in RAM35. When gate 38 is opened after one horizontal period, storage contents of memory 32 are read out and are written in RAM35. Consequently, the practical phase shift between error decision signals dependent upon detector 33, which completes decision at a one-horizontal period end time, and data signals is prevented by a simple constitution where the FIO and the RAM are used.
