Abstract
PURPOSE:To reduce the probability of the error detection of a digital data signal without increasing the redundancy of it by using a part of an ID signal as a synchronizing signal when the blocked digital data signal is detected based on the synchronizing signal by a receiving side. CONSTITUTION:At the time of normal reproduction, the output signal of each stage of a shift register 41 is compared with the pattern of 10-bit written in an ROM 42 and a detection signal SD is outputted by the ROM 42 when they are equal. In this manner, as the signal of 2 bit expressing the head number of the ID signal is used to detect the synchronizing signal besides the synchronizing signal SYNC at the time of the normal reproduction, the probability of the error detection of it is reduced to 1/2<2>=1/4. Thus, as it does not make the word of the signal SYNC to be increased, there is no defect to increase the redundancy of it.
