Method and apparatus for transmitting information, and reproducing apparatus, receiving apparatus and recording medium for the information, and transmission data thereof
View Patent ↗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.
1. An apparatus for transmitting signal information, which constitutes a transport stream that is multiplexed with at least video information by a transport packet,
wherein said signal information is transmitted with a flag in one bit, which directly and selectively designates an output signal format of said video information as an analog output signal format in a receiving apparatus side whether or not resolution of said video signal is limited to less than a predetermined resolution that is lower than original resolution of said video information.
