  • Publication number: 20070192697
    Abstract: 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.

  • Publication number: 20070067468
    Abstract: 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.

  • Publication number: 20050232597
    Abstract: 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.

  • Patent number: 5959675
    Abstract: A rate control for a VCR or the like records digitized image data by compression coding technologies so that the code amount of the compression coded data becomes a predetermined code amount or less. Even in the case where an interleave is performed among a plurality of blocks, the prediction error of the code amount after the interleave can be reduced and the rate control can be precisely performed by quantizing so that the same quantization table is assigned to each of the interleaved blocks in pre-scanning in the pre-stage of an interleave memory.

  • Patent number: 5543844
    Abstract: Input image data is divided into a plurality of blocks. An orthogonal transform device subjects the input image data to orthogonal transform every block. A memory temporarily stores output data from the orthogonal transform device. A first quantizer quantizes output data from the memory. A coding device codes output data from the first quantizer into variable-length code words. A code amount accumulation device accumulates a code amount of output data from the coding device. A second quantizer separates the output data from the orthogonal transform device into K different groups, and assigns M different scale factors to the respective blocks and quantizes the output data from the orthogonal transform device in the blocks with the related scale factors, where K and M denote predetermined natural numbers. A block code amount calculation device calculates a code amount per block.
