    摘要： A coding compression method for encoding the video image signal with a variable bit rate includes performing coding to the video image signal for each predetermined coding unit in accordance with a predetermined first coding parameter, which coding is completed within the coding unit, thereby generating a first coded stream, calculating a second coding parameter of the video image signal for each the predetermined coding unit while generating the first coded stream, indicating a partial section of the first coded stream, the partial section comprising the predetermined coding units, editing the second coding parameters corresponding to the designated subsections, performing coding to the video image signal of the designated subsections in accordance with the edited second coding parameters thereby to produce a second coded stream, and replacing a partial section of the first coded stream with at least a partial section of the second coded stream, the partial section of the second coded stream corresponding to the partial section of the first coded stream.

    摘要： On a recording medium, a monoscopic video specific section and a stereoscopic video specific section are continuous immediately after an extended data specific section. A shared section includes a continuous, interleaved arrangement having one each of main-view extents, sub-view extents, and extended extents. The stereoscopic video specific section includes a continuous, interleaved arrangement of extents having one each of the main-view extents and the sub-view extents. The monoscopic video specific section includes a continuous arrangement of a copy of the main-view extent arranged in the stereoscopic video specific section. The extended data specific section includes one of the extended extents that is to be used in combination with the copy of the main-view extent arranged in the monoscopic video specific section. The shared section is accessed when stereoscopic video images are played back, when monoscopic video images are played back, and when an extended stream is used. The stereoscopic video specific section is accessed during playback of the stereoscopic video images. The monoscopic video specific section is accessed during playback of the monoscopic video images. The extended data specific section and the monoscopic video specific section are accessed when the extended stream is read, immediately before or after a long jump.

    摘要： Provided is a production apparatus that can produce a distribution content that offers an even richer color tone expression during playback of video. The production apparatus for producing a distribution content including distribution video data is constituted by an original acquisition unit that acquires original video data; a distribution video acquisition unit that acquires the distribution video data, the distribution video data having been generated by conversion of the original video data to a lower gradation; a difference generation unit that generates difference data between the original video data and the distribution video data; and an output unit that outputs the difference data. A playback apparatus plays back the distribution content.
