Abstract: Time stamps are attached to packets output from stream data input section by a time stamp-attaching section in a HDD, and the packets are then recorded into a HDD main unit. A stream data-generating section removes the time stamps from the packets subsequent to a predetermined amount of packets last recorded into the HDD main unit and controls the timing of the packets according to the time stamps, and the packets are transferred to an HDD. In the HDD, time stamps start to be generated according to the last predetermined amount of packets, and to the packets transferred thereafter, time stamps are attached in a similar fashion as in the HDD, so that the packets are recorded into the HDD main unit.

Abstract: An information processing apparatus includes a reservation unit reserving predetermined processing for a broadcast program, the predetermined processing being started in accordance with conditions corresponding to program information concerning the broadcast program; a processing unit starting the processing, reserved by the reservation unit, for the broadcast program in accordance with the conditions; and an acquiring unit acquiring the program information. The reservation unit obtains program information concerning another broadcast program for which the processing is reserved and which is to be broadcasted subsequent to the broadcast program, the program information being acquired by the acquiring unit, if the processing reserved for the broadcast program is started by the processing unit. The reservation unit changes the conditions of the processing reserved for the other broadcast program in accordance with the obtained program information concerning the other broadcast program.

Abstract: In an image pick-up apparatus of the invention, when capturing is started, a chapter formation-commanding portion transfers a chapter table to a memory. When a user depresses a chapter formation button, a chapter is formed in an empty table of the chapter table. After completion of the capturing, the chapter formation-commanding portion transfers the chapter table stored in the memory to a storage portion. By performing the operation described above, a chapter can be formed in an arbitrary time position.

Abstract: A recording and reproducing module records a signal (broadcast program) based on a first compression method to a recording medium, and during a period of time during which recording is not performed, reproduces the signal based on the first compression method, which has been recorded to the recording medium. Then, a transcoding module transcodes the signal based on the first compression method to a signal based on a second compression method. The signal based on the second compression method, whose transcoding has been completed, is recorded to the recording medium; and the signal based on the first compression method is erased from the recording medium. The controller refers to recording history information and sets a schedule including a target broadcast program to be transcoded and a time zone in which the target broadcast program is transcoded.

Abstract: To provide the possible largest number of representative images of the image data recorded on the recording medium on the surface of a recording medium which is limited in size. When recording image data recorded on two DVD-Rs on a new DVD-R, a lenticular image synthesis is carried out on the representative images D1 and D2 provided on the surface of the original DVD-Rs and a representative image D3 of the new DVD-R to generate one synthetic representative image D10 and the synthetic representative image D10 is printed on the surface of the new DVD-R.

Abstract: The recording operation can be rapidly started and a notification about the operating state during the recording operation can be realized without adding a new component, whereby a target scene of a subject can be recorded reliably. When a video signal captured by a camera unit 10 is compressed and encoded and is recorded on a DV tape, a control unit 100 controls a compression/decompression unit 40 and a tape deck unit 60 to compress and encode the video signal and record as DV data without using compressed data already recorded on the DV tape. In other words, the control unit 100 controls the operation of compressing and encoding video data to be newly recorded in such a manner that compressed data already recorded on the DV tape is not read out, thus reducing the time until recording of the video data on the DV tape is started.

Abstract: A record/play device includes a recording unit that records, on a recording medium, a series content data sequentially input to the record/play device, a playback unit that plays back, while recording the data by the recording unit, the content data recorded on the recording medium, and a control unit that controls simultaneous record and play. The control unit includes a data size changing unit that changes a data size at which the content data is to be recorded on the recording medium to a data size different from a data size at which content data that has been recorded on the recording medium is recorded.

Abstract: A PLL control circuit of an optical disc apparatus comprising: a voltage frequency conversion circuit that adjusts an oscillating frequency based on a control voltage to generate a first frequency signal; a phase comparison circuit that compares the phase of the first frequency signal with the phase of a second frequency signal generated based on an RF (Radio Frequency) signal at the time of photoelectric conversion of reflected light of the laser beam applied to an optical disc, to generate a phase difference signal indicating a phase difference between the first frequency signal and the second frequency signal; a charge pump circuit that generates the control voltage for synchronizing the phases of the first frequency signal and the second frequency signal according to the phase difference signal; a first detection circuit that detects whether the RF signal exceeds a predetermined level; a second detection circuit that detects whether the phases of the first frequency signal and the second frequency signal

Abstract: A CDA processing section extracts an unused area of an information recording medium via a disc status management section and a drive control section. The CDA processing section divides the extracted unused areas by a division criteria value MAS, which allows continuous reproduction of a video and audio stream, and reserves areas having the size of the division criteria value MAS as CDAs. This enables continuous reproduction of AV data, and multiple data can be recorded simultaneously.

Abstract: A method of hierarchical image indexing which extracts representative images of a TV program and generates a hierarchical index image guide of the representative images, and an apparatus therefor. Respective images at predetermined times are extracted from a predetermined program. A hierarchical index is allocated to each extracted image and the indexes are mapped to locations of transport stream packets. A tree of images having the allocated indexes is constructed as a hierarchically indexed Image guide (HIIG). When a stored program is to be reproduced, a location desired to be watched is selected in the HIIG, and from the selected location, reproducing and trick plays (FF, rewind) are enabled such that a user easily searches the program and begins viewing the program at the searched for location.
