Abstract

PURPOSE: To detect an editing point by error distribution characteristics of a signal, recorded on the multitrack of a recorded PCM magnetic tape, at the editing point of the magnetic tape, by delaying a track where a PCM signal has been distributed.
CONSTITUTION: An analog input signal to terminal 1 is modulated by an A/D converter into a PCM signal, which is distributed to respective tracks by code adding circuit 3 and also given an additional error detecting code. Signals to some of tracks are delayed by a constant number of frames at delay circuit 4 and recorded via modulating circuit 5. A reproduced signal is PCM-demodulated by demodulating circuit 9 and supplied to error detecting circuit 10 for a PCM signal to detect its error. The error detection output result is led to editing processing circuit 13 by way of editing detecting circuit 12. The reproduced PCM signal is converted in time series into one by the parallel-series converting circuit, whose output is edited by editing processing circuit 13 before being outputted via A/D converter 14.
