Abstract
An output control (OPC) information is recorded on the magnetic tapein conjunction with an MPEG stream. The OPC information is composed of two bits and is extracted from a reproduced signal by the output control circuitand controls the digital interface (D. I/F)and the switch circuit. In case a first bit of the OPC information is '0', the output control circuitmakes the D. I/Fenabled and permits the output of a digital signal. In a case of '1', the output control circuitprohibits to output the digital signal. Further, when the second bit of the OPC information is “0”, the output control circuitturns the switch circuitoff, preventing the output of an analog component signal. In case its “1”, the output control circuitpermits the output of the analog component signal.
