Abstract

PURPOSE:To promote the reliability of reproducing data in simple constitution by performing also the coincidence detection as to a subcode 10 in addition to the coincidence detection of PCM-ID. CONSTITUTION:The coincidence detections of the PCM-ID and the subcode ID are performed by a coincidence detection part 6. A latch signal and a reset signal, etc., are outputted, based on data and clocks, etc., outputted from an 8-10 demodulation part 5, by a coincidence detection control part 7 to control the coincidence detection part 6. The ID detected of coincidence by the detection part 6 are held in a prescribed output register. Subsequently, the held PCM-ID and subcode ID are read out by microcomputer 9 via a microcomputer interface 8, and the microcomputer 9 executes individual processes of discriminating a program number, etc., in response to each individual ID. Because of the coincidence detection having performed, high reliability processes can be carried out.
