ABSTRACT:
An identification code processing apparatus for digital VCR's wherein data is recorded along with identification codes on a tape so that when an error is generated upon reproducing the identification codes, it is corrected using a reference identification code internally generated, thereby enabling the recorded data to be correctly reproduced. The apparatus includes an identification code adding unit for generating frame and block identification codes on the basis of frame and block synchronous codes and a clock signal, and adding the generated frame and block identification codes to input video data, thereby outputting the resultant video data added with the frame and block identification codes, the identification code adding unit also generating marking signals respectively obtained after encoding frame and block synchronous signals respectively indicating positions of the frame and block identification codes, and an identification code error correcting unit for detecting the identification codes respectively from the block synchronous signals received after being reproduced, comparing each of the detected identification code with a corresponding count identification code generated by the clock signal received after being reproduced, and correcting errors of the identification codes based on the result of the comparison.
