摘要:
In a video signal recording/reproducing apparatus for emphasizing an input video signal, recording by adding an additional signal necessary for recording, and de-emphasizing when reproducing, the emphasis processing is stopped on the time axis in a period in which the additional signal is to be added. Besides, by adding an additional signal before emphasis processing, the waveform deterioration in the end portion of the effective period occurring due to the addition of additional signal after emphasis processing is decreased, and a favorable waveform reproduction is realized over the entire period of the effective portions.

To allow the user to specify easily a frame when video, of which the frame rate (or vertical scanning frequency) has been converted, is being edited.A data processor includes: a receiving section for receiving a signal representing first video in which a plurality of pictures are presented at a first frequency; an encoder for generating a data stream representing second video, in which the pictures are presented at a second frequency, different from the first frequency, based on the signal; and a writing section for writing the data stream on a storage medium. The encoder generates picture data about the respective pictures, first time information indicating presentation times at the first frequency, and second time information indicating presentation times at the second frequency, and stores the first time information, the second time information and picture data of the respective pictures to be presented based on the first time information in association with each other, thereby generating the data stream.

Files are capable of being exchanged between a broadcast device and a personal computer. In a file of an AV multiplex format, a header (size and type information) of a skip atom of QT is described at the beginning (run-in) that is ignored in an MXF file. An MXF header is described in the skip atom that is skipped over in a QT file. A movie atom and a mdat header of QT are described in a filler that is ignored in the MXF file. In other words, a file header portion of the AV multiplex format satisfies both the structure of the MXF file and the structure of the QT file. With this file structure, a file of the AV multiplex format can be recognized by both an MXF standard basis edit device and a QT software installed PC. The present invention can be applied to a picture record device.

A video recording apparatus provides a slow motion effect or a quick motion effect by digitally converting the frame-rate instead of by changing the playback speed of the film, and using few recording media without requiring any special device at playing. A picture encoding part encodes only valid frames by changing a rate-controlling method so that a predetermined playing frame-rate is obtained at a standard data-rate at playing. And a TS multiplexing part multiplexes by converting a frequency of a standard STC clock by only a ratio of valid frame-rate and playing frame-rate, and generating values for PCR, PTS, and DTS.

A recording and reproducing apparatus (100) can record information on a recording memory (111) having a recording region where a smallest unit for erasing recorded information is a block, on a unit of a cluster that is a unit smaller than the block. The recording and reproducing apparatus (100) includes: an input unit (130) that receives a request for starting or ending recording a file; and a system control unit (101) that records a header section of the file and a data section following the header section, from the beginning of the block in the recording region, when the request for starting recording is received; and updates the header section and records the updated header section on another cluster different from the cluster on which the header section before update is recorded when the request for ending recording is received. The system control unit (101) further corrects management information indicating a connection order of information recorded on each of the clusters included by the recording medium so that the updated header section is followed by the data section, when the updated header section is recorded on the other cluster.

To improve the convenience of a record medium and allow a record process and reproduction process to be more easily performed than before. When a clip edit list update process 121 that updates video data and audio data recorded on a disc 32 is executed, an index file management section 72 manages and updates an index file held in an index file hold section 51 as the video data and audio data are updated. At this point, a search section 92 searches disc internal IDs assigned to clips or edit lists contained in the index file for the maximum value. A disc internal ID generation section 91 generates a disc internal ID according to the maximum value. An index file management section 72 updates the index file with the disc internal ID generated by the disc internal ID generation section 91.

To allow the determination of whether data can be reproduced to be easily performed. When a plurality of clips generated by a photographing process are connected as an edit, an edit list management section 15 identifies encoding systems of a plurality of clips (video files) to be connected and writes the identified encoding systems to an edit list file that manages an edited result. An optical disc 30 on which a clip, an edit list file, and so forth have been recorded is loaded into another reproduction apparatus. When a command that causes an edited result recorded on the optical disc 30 to be reproduced is input to the other reproduction apparatus, the reproduction apparatus reads encoding systems written in the edit list file and determines whether the encoding systems are systems for which that the reproduction apparatus can decode data. In this manner, the reproduction apparatus determines whether it can reproduce the edited result. The present invention can be applied to an edit apparatus that edits for example pictures and so forth.

According to the embodiment, there is provided a recording apparatus which time-divides a stream of continuous video or audio signals into a first stream and a second stream, records the first stream on a first recording medium as a first file, and records the second stream on a second recording medium as a second file. First management information related to a manufacture code number, being unique to a medium, for specifying the second recording medium is recorded on the first recording medium in association with the first file, or second management information related to a manufacture code number, being unique to a medium, for specifying the first recording medium is recorded on the second recording medium in association with the second file.
