Abstract: A signal recording/reproducing method and apparatus, a signal record medium, and a signal transmission/reception method and apparatus enable a signal recorded on a signal record medium to be identified as being an original signal or a copied signal. A CPU (11) generates, at a pre-set time interval, an identification signal having a meaning at a pre-set time interval, and an identification signal addition circuit (3) adds the identification signal to video signals and/or audio signals. A sector forming circuit (5) and circuit components up to a recording/reproducing head (14) record the video signals and/or the audio signals and the ancillary identification signal on an optical disc (12).

Abstract: A data reproducing apparatus reproduces a recording medium recorded recording data which have auxiliary data added to main data subjected to an error correction coding process. The data reproducing apparatus includes a signal processor (4), a memory (6), a comparator and a controller (5). The signal processor (4) separates the main data from the recording data read out from the recording medium to implement a error correction decoding process thereto. The memory means (6) stores the decoded main data from the signal processor. The comparator compares last data stored in the memory with the inputted main data to the memory. The controller (5) controls write and read operations of the memory (6) and controls comparison condition of the comparator according to the main data from the signal processor (4).

Abstract: Data are recorded on an optical disk (1) by adding double parities of internal and external parities to the data. The internal parity is added to interleaved data and used for the correction of internal codes, and the external parity is added to non-interleaved data and the internal parity and used for the correction of the external codes. Reproduced data from the disk (1) are supplied to and stored in a ring buffer memory (5) and, at the same time, supplied to an error correction circuit (71) which corrects the errors in the external codes. The correction results are supplied to the memory (5) and overwritten therein. The data stored in the memory (5) are again read out to the circuit (71) and the errors in the internal codes are corrected. For sector address detection by a sector detection circuit (72), the data of which the errors of the external codes are corrected are used. In special reproduction, only the external code correction is performed.

Abstract: PROBLEM TO BE SOLVED: To obtain the extraction operation of a proper regenerative clock at all times regardless of the signal state. SOLUTION: When a linking-point indication signal PLKP, a defect detecting signal DFCK and a peak detecting signal PKLV are acquired, a switch control section 36 executes changeover control to a switch 31 so that a recording clock WTCK is input to a phase-frequency measuring circuit 32 in place of a binarised RF signal D-RF for a fixed period. Accordingly, the oscillation frequency of a VCO(voltage controlled oscillation circuit) 34 can be controlled so as to be maintained in required regenerative clock frequency regardless of the miss of a regenerative signal.

Abstract: PROBLEM TO BE SOLVED: To obtain proper asymmetry compensation operation at all times regardless of the signal state. SOLUTION: When a linking point indicating signal PLKP, a defect detecting signal DFCT and a peak detecting signal PKLV are acquired, the on-off states of switches SW1-SW4 are controlled so that the time constant of a filter section 31 is made smaller than or larger than a standard for a fixed period in a switch control section 32. Accordingly, a threshold TH for correcting asymmetry is followed up at high speed in response to a signal state or, conversely, a preceding threshold TH is held regardless of the state of an input signal for a linking section or a regenerative-signal mission period.
