<p>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 other words, in a case that a first bit of the OPC information is "0", the output control circuit 9 makes the D. I/F 7 enable and permits to output a digital signal. In a case of "1", the output control circuit 9 prohibits to output the digital signal. Further, in a case that a second bit of the OPC information is "0", the output control circuit 9 turns the switch circuit 11 off and prohibit to output an analog component signal. In a case of "1", the output control circuit 9 permits to output the analog component signal.</p> |
