PURPOSE:To record and regenerate the digital signal of high sound quality by recording the digital signal of a second format by being divided to a pair of recordable areas, at least, of a first format. CONSTITUTION:Out of the respective areas, for which 2n equal division (12 channels) of one track is executed, a pair of the recordable areas are detected at least. The digital signal of the second format, for example, the PCM data of 16 bits are divided and recorded to these detected areas. Accordingly, even when the areas, in which the PCM data of 8 bits are already recorded and remained, are respectively separated, those areas are coupled and the PCM data of the 16 bits can be recorded. Then, a multi-channel recording area can be effectively utilized. Thus, the digital signal of the high sound quality can be recorded and regenerated.

PURPOSE:To reduce the bit error rate by using an equalizer circuit so as to apply equalizing processing to a pickup signal. CONSTITUTION:A digital signal detection circuit 5 gives a pickup signal S1 sent from a reproducing head 4 via a reproducing amplifier circuit 11 to a 1st equalizer circuit 12. The circuit 12 adds (12F) outputs of an input terminal and an output terminal of delay circuits 12A, 12B via weighting circuits 12C-12E and gives an output S2 to a 2nd equalizer circuit 13. The circuit 13 receives the output S2 at its integration circuit 13A and its differentiation circuit 13B, adds (13C) the integration output S3 and the differentiation output S4 and gives the output S5 to the equalizer circuit 14. The circuit 14 applies equalizing processing against the frequency distortion to send an output S6. An equalizer circuit 15 receiving the output cuts off the frequency component higher than the Nyquist frequency and sends an output S7. The output S7 is compared 21 with a zero cross reference voltage S11, a comparison output S12 is given to a synchronizing circuit 23 and a clock generation circuit 25 and outputs a data detection signal SDT from the circuit 23 via a reproducing clock signal from the circuit 25.

PURPOSE:To reduce a bit error rate by controlling a clock frequency to be changed with a clock reproducing circuit constituting a phase locked loop circuit, at the time of demodulating digital data recorded on a magnetic recording medium. CONSTITUTION:Data recorded by 1st and 2nd recording modulation systems respectively in different recording density from each other on the magnetic recording medium 3 are picked up by the tilted data reproducing device, so as to obtain a reproducing clock signal CK10 from a clock component included in a pickup output SPB (DTPB) by means of the clock reproducing circuit 11 constituting the phase locked loop circuit, and the output SPB (DTPB) is demodulated based on the signal CK10. A control signal CNT corresponding to the 1st or 2nd recording modulation system is sent by a control circuit 15 to switch circuits 14 and 17. By this method, a reference signal frequency of the clock reproducing circuit 11 and a time constant of an LPF circuit 16 are changeably controlled, thus obtaining the signal CK10 consisting of an optimum phase, so that the bit error rate at the time of demodulating can be reduced.
Abstract:
PURPOSE:To omit the manual readjustment job of a tracking manual adjustment means in case of most of the recording media free from the tracking adjustment after the reproduction of a recording medium which scarcely requires the tracking adjustment, by resetting the tracking manual adjustment means when a recording medium is loaded and unloaded. CONSTITUTION:For instance, a switch 101 is depressed in a reproduction mode of a tape recorded on other VTR for tracking adjustment. Thus such a control signal that increases gradually the delay value while the switch 101 is depressed is supplied to a delay circuit 15 from a microcomputer 100. While such a signal that decreases gradually the delay value to which a switch 102 is depressed is supplied to the circuit 15 from the computer 100. Thus a tracking position is manually adjusted. Then a reset signal is supplied to the computer 100 through an input terminal 103 for tracking adjustment reset signal when a tape is unloaded. Thus the tracking manual adjustment is reset and the adjustment value is set at 0, i.e., a just tracking state is secured with its own recording tape.

PROBLEM TO BE SOLVED: To add other audio signals, while effectively allowing audio signals in an original video content to remain depending on the scene. SOLUTION: A recording playback apparatus 100 detects a facialimage region from an image signal of a video content to calculate a face evaluation value Tf, and detects a voice from an audio signal to calculate a voice evaluation value Tv. The recording playback apparatus 100 is such that if the face evaluation value Tf is not smaller than threshold Tfs and the voice evaluation value Tv is not less than threshold Tvs, the weighting factor k of BGM sound is set at a small value of k1, as much as possible; if the face evaluation value Tf is less than the threshold Tfs and the voice evaluation value Tv is less than the threshold Tvs; the weighting factor k is set at a large value k2, as much as possible; and if any one of the face evaluation value and the voice evaluation value is not less than the, the weighting factors k and m are set, corresponding to the face evaluation value and the voice evaluation value.

When a specified chapter representing image 57 is put together by the marker 55 and selected on the chapter bar 56, a video content is reproduced from the chapter. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To allow a user to save labor and time for selection concerning the kinds of a stream to be recorded, such as recording medium and system for fetching the stream. SOLUTION: When the prescribed stream recorded in the recording medium A is recorded in a prescribed recording medium B which is one of the media arranged in a tray, the system for recording the stream to be recorded is confirmed at first. A recording medium control system 306 confirms the recording systems to correspond to the respective recording media B arranged in the tray. When the stream to be recorded is the stream which is fetched by the recording system 2 and the recording medium corresponding to the recording system 2 (the recording medium having a recording layer corresponding to the recording system 2) is arranged in the tray, the stream to be recorded is recorded in the recording medium. The present invention is applicable to a recording apparatus capable of handling one or not less than two recording media. COPYRIGHT: (C)2007,JPO&INPIT
