摘要： A signal conversion recording method applies a signal recording method whereby a video signal converted to a frame rate greater than the frame rate of the signal source by repeating particular fields plural times is converted to an intermediate signal having a frame rate substantially equal to the frame rate of the original signal source by deleting these repeated redundant fields. This intermediate signal is compression coded to obtain the recording signal, and the recording signal is recorded to a recording medium together with a repeat first field flag RFF declaring whether a field was deleted, and a top field first flag TFF declaring which of the two fields in the each of the resulting frames is first on the time-base, wherein when plural logical recording periods are provided on a single recording medium, said video signal is converted to the recording signal so that said flags hold particular values at the start and end of each recording period.

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.
