ABSTRACT:
An output control (OPC) information is recorded on the magnetic tape1in conjunction with an MPEG stream. The OPC information is composed of two bits and is extracted from a reproduced signal by the output control circuit9and controls the digital interface (D. I/F)7and the switch circuit11. In case a first bit of the OPC information is “0”, the output control circuit9makes the D. I/F7enabled and permits the output of a digital signal. In a case of “1”, the output control circuit9prohibits to output the digital signal. Further, when the second bit of the OPC information is “0”, the output control circuit9turns the switch circuit11off, preventing the output of an analog component signal. In case its “1”, the output control circuit9permits the output of the analog component signal.
