    摘要: An HDTV signal transmission system for sending a 10-bit-parallel YPbPr-format HDTV signal converted to ten C4 containers, and further to the SDH (a new synchronous digital network) STM-16 frame for transmission based on CCITT recommendations. The system includes a transmitter and receiver. The transmitter has time dividers for time-based dividing the HDTV signal into eight separated video signals, a C4 container device for multiplexing the eight separated video signals to ten C4 containers, and a STM-16 framing device for reformatting the ten C4 containers to the STM-16 frame. The receiver has an STM-16 deframing device for separating the ten C4 containers from the STM-16 frame, a C4 de-container device for demultiplexing the ten C4 containers to eight separated video signals, and time-division multiplexers for time-division multiplexing the separated video signals to the 10-bit-parallel YPbPr-format HDTV signal.

    摘要: In order to cope with format conversion of user data, the bit rate value and VBV (Video Buffering Verifier) buffer size value in a sequence header of an input code and the VBV delay value in a picture header of the input code are modified to obtain an intermediate code (305 to 309), and additional information (300) is generated for distinguishing GOP (Group of Pictures) user data (307) from the other main data. A VBV buffer simulation is performed using this additional information (300) to multiplex the GOP user data in a picture user data region to a data amount such that the operation does not fail, whereby an output code is generated.

    摘要: A recording/reproduction apparatus includes a first recording medium (a flash memory) having a first time that is required for the first recording medium to go from a low-power consumption state to a state in which recorded video data can be read out, and a second recording medium (an HDD or a DVD drive) having a second time that is required for the second recording medium to go from a low-power consumption state to a state in which recorded video data can be read out, where the second time is longer than the first time. When a video content is reproduced from the second recording medium in the low-power consumption state, the first recording medium is caused to go to a readable state while the second recording medium is not in a readable state, and a leading portion of the content is reproduced from the first recording medium. Thereby, a start-up time of the second recording medium that is required until reproduction is permitted is concealed from the user, and the user's reproduction request is immediately responded.

    摘要: A format converter for converting the format of input contents data from a first format standard to a second format standard includes an extraction section (30), a judgment section (40), a determination section (60) and a conversion section (70). The extraction section (30) extracts information related to encoding of the input contents data. The judgment section (40) judges whether or not the contents data satisfies a constraint placed by the second format standard based on the extracted information. The determination section (60) determines whether or not decoding of the contents data is necessary for the format conversion based on the judgment result. The conversion section (70) performs the format conversion by converting data structure when it is determined that the decoding is unnecessary.
