Abstract

PURPOSE:To improve the error detecting ability of a control code by deciding whether the control code is correctly reproduced or not according to the result of parity check, the detection information of a synchronizing signal and the result of block address check. CONSTITUTION:Digital data, inputted from an input terminal 42, is inputted to the data conversion circuit 30 and the synchronizing signal detection circuit 31 of a demodulator 11, and the synchronizing signal detection circuit 31 outputs a synchronizing signal detection signal, and the data conversion circuit 30 performs the conversion of the data. The output of the data conversion circuit 30 is inputted to registers 33-35 and a parity check circuit 36. The parity check circuit 36 sums the control code, a block address and a parity, and a parity decision circuit 37 decides whether the data was correctly reproduced or not according to the result of the parity check, the detection information of the synchronizing signal and the result of the block address check.
