Abstract: A coding device (100) performs division into a plurality of blocks by using a block division mode set obtained by combining one or more block division modes which define division types. The block division mode set comprises: a first block division mode in which the number of divisions and the dividing direction for dividing a first block are defined; and a second block division mode in which the number of divisions and the dividing direction for dividing a second block, which is one of blocks acquired by dividing the first block are defined. When a division in the first block mode results in three blocks, the second block is the center block among the blocks acquired by dividing the first block, and the dividing direction of the second block division mode is the same as the dividing direction of the first block division mode, then the second block division mode includes only a block division mode in which a division results in three blocks.

Abstract: RECORDING MEDIUM, PLAYBACK METHOD, AND PLAYBACK DEVICE Recorded in a recording medium are a video stream of standard-luminance range, and a video stream of high-luminance range that is a broader luminance range than the standard-luminance range, which are used selectively in accordance with a playback environment, a subtitle stream of the standard- luminance range, and a subtitle stream of the high-luminance range, which are used selectively in accordance with the playback environment, and a playlist file storing playback control information of content, playlist file including a management region where the playback control information relating to a main stream is stored, and an extended region. The management region stores first playback control information specifying that a video stream of the high-luminance range and a subtitle stream of the high-luminance range are to be played in combination. The extended region stores second playback control information specifying that a video stream of the standard-luminance range and a subtitle stream of the standard-luminance range are to be played in combination.

Abstract: Provided is a recording medium in which the following are recorded: a video stream in a standard brightness range and a video stream in a high brightness range that is wider than the brightness range of the standard brightness range, said video streams being used selectively in accordance with the reproduction environment; a subtitle stream in a standard brightness range and a subtitle stream in a high brightness range, said subtitle streams being used selectively in accordance with the reproduction environment; and a playlist file in which content reproduction control information is stored, said playlist file comprising a management area in which reproduction control information relating to a main stream is stored and an extension area. First reproduction control information specifying that the video stream in the high brightness range and the subtitle stream in the high brightness range are to be combined and reproduced is stored in the management area and second reproduction control information specifying that the video stream in the standard brightness range and the subtitle stream in the standard brightness range are to be combined and reproduced is stored in the extension area.

Abstract: Se proporciona un método de presentación visual para presentar visualmente, en un dispositivo de presentación visual, video de datos de video donde la luminancia de video está definida por una primera EOTF (función de transferencia electro-óptica) que indica una correlación de luminancia de HDR (alto intervalo dinámico) y valores de código. El método incluye: adquirir los datos de video; llevar a cabo, con respecto a cada uno de una pluralidad de pixeles que componen el video incluido en los datos de video adquiridos, primera determinación de determinar si la luminancia de ese pixel excede o no una primera luminancia predeterminada; llevar a cabo, con respecto a cada uno de la pluralidad de pixeles, asignación de tonos dual donde la luminancia de ese pixel se reduce por un formato diferente en caso de que se encuentre que la luminancia del pixel supera la primera luminancia predeterminada como resultado de la primera determinación, y en caso de que se encuentre que la luminancia del pixel es igual o inferior a la primera luminancia predeterminada; y presentar visualmente el video en el dispositivo de presentación visual usando los resultados de la asignación de tonos dual.
