Abstract
PURPOSE:To prevent the occurrence of abnormal data in case of connection of a different kind of PCM data, by inhibiting error correction when the error detection output of the PCM reproducing signal exceeds a prescribed value. CONSTITUTION:Signal processing device 2 performs the interleave/deinterleave processing for the PCM signal corresponding to VTR1 and corrects errors. In this case, if the error caused by mixture of different kinds of data occurs according to the operation of change-over switch 6 of VTR1, decoder 17 of device 2 detects in 38 that the output due to error detection 30 exceeds a prescribed value related to the unit delay quantity for interleave/deinterleave and is generated successively, and control signal PC2 based on this detection and another control signal PC1 are used to inhibit error correction 32. As the result, the occurrence of abnormal data due to the error correcting operation which uses different kinds of PCM data is prevented.
