摘要:
An output control (OPC) information is recorded on the magnetic tape 1 in conjunction with an MPEG stream. The OPC information is composed of two bits and is extracted from a reproduced signal by the output control circuit 9 and controls the digital interface (D. I/F) 7 and the switch circuit 11. In case a first bit of the OPC information is “0”, the output control circuit 9 makes the D. I/F 7 enabled and permits the output of a digital signal. In a case of “1”, the output control circuit 9 prohibits to output the digital signal. Further, when the second bit of the OPC information is “0”, the output control circuit 9 turns the switch circuit 11 off, preventing the output of an analog component signal. In case its “1”, the output control circuit 9 permits the output of the analog component signal.
