    摘要: There is provided a highly flexible television multiplex data extracting apparatus which can fetch the multiplex data of the television broadcast services where the horizontal section for multiplexing data is not fixed, wherein a register receives an information from a controller to generate information for designating the horizontal section for fetching multiplex data, sampling frequency information of the data to be multiplexed and information for designating fetch of data, a sampling apparatus has the first and second fetch modes and detects any one mode of the first and second modes depending on the information from the register, the first mode is the extracting mode corresponding to the case where the horizontal section for multiplexing data is fixed and the second mode is designated to discriminate existence of the multiplex data in the designated horizontal section and fetch the data depending on the discrimination result.

    摘要: Only the data sampled by a correct sampling clock is data processed. A PLL circuit 5 generates a sampling clock locked with a sync signal in a video signal and supplies to a sampling circuit 4. A lock flag indicating whether the generated sampling clock is correctly synchronized with the sync signal or not is also generated. The data multiplexed to the sync signal is sampled by the above sampling clock. The data is stored in a memory 7. The lock flag is supplied to a controller 2 and the data that is outputted from the memory 7 is made valid or invalid according to the level of the lock flag.

    摘要: A signal reproducing method and apparatus in which the generation limitation information, such as a token or a ticket, contained in digital data, is recorded in analog signals. A reproducing device 20 reproduces, from a source disc S, picture data etc having the superimposed copyright control information for copying limitation and a ticket representing the generation limitation information specifying the number of times of possible copying or reproduction. The reproducing device 20 converts the picture data etc into analog baseband signals and detects the ticket. The reproducing device 20 superimposes the detected ticket on audio signals by watermark processing to output the resulting analog baseband signals.

    摘要: An information signal reproducing apparatus for reproducing an information signal from a recording medium on which the information signal, including added copy control information is recorded, comprising a first detector for detecting whether the information signal read out from said recording medium is encrypted or not-encrypted and for producing an output representative thereof; a second detector for detecting said copy control information from the information signal read out from the recording medium and for producing an output representative thereof; and a controller for selectively restricting reproduction of the information signal based on the outposts of the first detector and the second detector.
