Abstract
PURPOSE: To facilitate and secure editing processing as to PCM signals by recording and distributing a PCM signal to tracks with different delay and by judging an editing point on the basis of the detected dissidence of not less than two kinds of detection codes.
CONSTITUTION: A PCM signal, after longitudinal and laterial codes are added by product code adding circuit 3, is differentially delayed and distributed to and recorded on, for example, eitht tracks. Those records are reproduced andmodulated and further checked by CRC check circuit 10 and when frames of all tracks are erroneous, the 1st editing detecting circuit 12 generates the 1st editing detection signal. Further, the PCM signal demodulated by fixed delay circuits 4... and decoding circuit 11 is supplied to the 2nd editing detecting circuit 13 to detect an error missed at curcuit 10 and on the basis of double detection by the detected dissidence of not less than two kinds of error detection codes, editing processing such as discrimination of PCM signals at, before and after the editing point is carried out easily and securely neither by varying the tape speed nor by double writing.
