Abstract: Provided are video encoding device that encodes high-quality video, restricting increase of the required bandwidth, while maintaining playback compatibility with playback devices conforming to MPEG-2 standard, and video playback device. Data creation device 5401 includes: 2D compatible video encoder 2602 that generates stream conforming to MPEG-2 format by compress-encoding original video of normal quality; base-view video encoder 2605 that generates stream, composed of black images, that includes the same number of pictures as stream that is obtained by compress-encoding original video; and dependent-view video encoder 5409 that generates dependent-view video stream by compress-encoding higher-quality original video, by using, as reference pictures, pictures included in stream conforming to the MPEG-2 format that have the same time information as pictures included in the base-view video stream that correspond to pictures constituting higher-quality original video.

Abstract: Un medio de grabación en el que se graba información de lista de reproducción y un archivo de flujo, donde el archivo de flujo guarda un flujo de transporte en el que una pluralidad de flujos elementales han sido multiplexados; la pluralidad de flujos elementales son flujos elementales en paquetes; la información de lista de reproducción incluye una tabla de selección de flujo básico (STN_table) y una tabla de selección de flujo de extensión (STN_table_SS); la tabla de selección de flujo básico (STN_table) muestra una pluralidad de pares de entrada de flujo y atributo de flujo respectivamente en asociación con una pluralidad de números de flujo que representan respectivamente la pluralidad de flujos elementales, incluyendo cada atributo de flujo un atributo de idioma que ha de ser comparado con un parámetro de idioma en un dispositivo de reproducción cuando el dispositivo de reproducción ejecuta un procedimiento de selección de flujo para seleccionar un número de flujo actual, y cada entrada de flujo incluye un identificador de paquete que indica un paquete de flujo de transporte (paquete TS) que ha de ser un objetivo de desmultiplexación cuando un número de flujos correspondiente se selecciona como un número de flujo actual en un modo de reproducción monoscópica; la tabla de selección de flujo de extensión (STN_table_SS) muestra una pluralidad de entradas de flujo respectivamente en asociación con la pluralidad de números de flujo indicados en la tabla de selección de flujo básico (STN_table), incluyendo cada una de la pluralidad de entradas de flujo un identificador de paquete que indica un paquete de flujo de transporte (paquete TS) que ha de ser un objetivo de desmultiplexación cuando un número de flujos correspondientes representados en la tabla de selección de flujo básico (STN_table) se selecciona como un número de flujo actual en un modo de reproducción estereoscópica conmutado del modo de reproducción monoscópica.

Abstract: A main-view stream, a sub-view stream, and management information are recorded on a recording medium. The management information includes the system rate of each stream. Each stream is divided into a plurality of data blocks and forms a plurality of extent blocks. In each extent block, main-view data blocks and a sub-view data blocks are arranged alternately in a continuous manner. The maximum value of the size of the main-view data block and sub-view data block forming a single pair is determined in accordance with the following conditions: (i) the system rate of the sub-view stream; (ii) whether or not the pair is the leading pair in an extent block; (iii) whether or not a long-jump region exists between two extent block recording regions read in succession.

Abstract: The recording medium 100 stores playlist information and a plurality of elementary streams. The playlist information includes a basic stream selection table and an extension stream selection table. The basic stream selection table shows elementary streams that are permitted to be played back in a monoscopic playback mode. The extension stream selection table shows elementary streams that are permitted to be played back only in a stereoscopic playback mode. The stream entry in the extension stream selection table indicates a packet identifier that is to be used by the playback device to perform demultiplexing when the playback device is in the stereoscopic playback mode and the corresponding stream number is set in the stream number register provided in the playback device.

Abstract: On a recording medium, stereoscopic and monoscopic specific areas are located one after another next to a stereoscopic/monoscopic shared area. The stereoscopic/monoscopic shared area is a contiguous area to be accessed both in stereoscopic video playback and monoscopic video playback. The stereoscopic specific area is a contiguous area to be accessed immediately before a long jump occurring in stereoscopic video playback. In both the stereoscopic/monoscopic shared area and the stereoscopic specific area, extents of base-view and dependent-view stream files are arranged in an interleaved manner. The extents on the stereoscopic specific area are next in order after the extents on the stereoscopic/monoscopic shared area. The monoscopic specific area is a contiguous area to be accessed immediately before a long jump occurring in monoscopic video playback. The monoscopic specific area has a copy of the entirety of the extents of the base-view stream file recorded on the stereoscopic specific area.

Abstract: Provided is an image transmission device for transmitting an image to an image playback device in a manner such that it is possible to recognize a transmission channel for an additional-view image which is transmittable along various transmission channels, and to play a 3D image. An image transmission device for transmitting an image is equipped with: a storage means for storing a plurality of images to be transmitted through a plurality of virtual channels, and virtual-channel information including definition information for defining each of the plurality of virtual channels; and a transmission means for transmitting the images and virtual-channel information through the plurality of virtual channels. Therein, the plurality of images stored in the storage means include one of two images for configuring a 3D image and captured from different viewpoints, while the definition information for the virtual channel for transmitting this one image includes transmission-form information expressing the form of transmission for the other image for configuring the 3D image.

Abstract: A pair of main-view and sub-view video streams and a graphics stream are recorded on a BD-ROM disc. M etadata is provided in each GOP in the sub-view video stream. The metadata includes offset information. The offset information specifies offset control for a plurality of pictures constituting a GOP. Offset control is to provide a left offset and right offset for the horizontal coordinates in a graphics plane to generate a pair of graphics planes, and to combine them separately with main-view and sub-view video planes. The sub-view video stream is packetized and multiplexed in a transport stream. A header of each TS packet includes a TS priority flag. TS packets containing the metadata have a different value of TS priority flag from TS packets containing sub-view pictures.
