摘要： The present invention displays subtitles in a language desired by a user in a desired format. A text data decoder 121 decodes text subtitle data, supplies a character object to a character object buffer 122, and supplies attribute data to an attribute data buffer 123. The attribute data stored in the attribute data buffer 123 is changed on the basis of an operation input from the user. A font rasterizer 124 converts the character object into raster data on the basis of attribute specification read from the attribute data buffer 123 and acquired font data, and outputs the raster data. By detecting each character object bearing a bookmark on the basis of the attribute and using a bookmark buffer 125, character objects bearing the same bookmark ID are prevented from being repeatedly rasterized. The present invention is applicable to a playback apparatus.

摘要： For a large capacity recording medium, a user interface having high flexibility and enriched representation is accomplished. A flag that represents whether a play item has a multiple angle structure of which the play item is reproduced with a plurality of angles is described. In addition, a flag that represents whether the beginning of each decode unit is an angle switchable point is described. In a seamless multiple angle structure, the current angle can be switched without need to increase the number of interleave units. In a nonseamless multiple angle structure, with the flag, in a predetermined region on the rear end side of each angle, the current angle is prohibited from being switched. Thus, when a play item exits from the multiple angle, discontinuity in the reproduction can be prevented. In addition, with a flag that represents whether a sub play item should be reproduced not in synchronization with a main path, the sub play item of only audio data can be used as a BGM.

摘要翻译： 对于大容量记录介质，实现了具有高灵活性和富集表示的用户界面。 描述表示播放项目是否具有以多个角度再现播放项目的多角度结构的标志。 此外，描述表示每个解码单元的开始是否是角度切换点的标志。 在无缝多角度结构中，可以切换当前角度，而不需要增加交织单元的数量。 在非缝合多角度结构中，通过标志，在每个角度的后端侧的预定区域中，禁止当前角度切换。 因此，当播放项目从多个角度退出时，可以防止再现中的不连续性。 此外，通过表示子播放项目是否应与主路径不同步再现的标志，只有音频数据的子播放项目可以用作BGM。

摘要： The present invention relates to an information processing apparatus, an information processing method, a program, and a data structure for processing a stream including a base stream and extension streams at a plurality of levels. A transmitter encodes an audio stream into a base stream BS and first to n-th extension streams Ext1 to ExtN. The transmitter refers to tables 90 and 91, generates TS packets 92 and 93-1 to 93-n having PIDs for the corresponding types of streams and the TS packets 90 and 91 of the tables, and outputs the generated TS packets to a receiver. The receiver refers to the TS packets 90 and 91 of the tables and determines the type(s) of stream(s) that it can process. The receiver selects the TS packets having the PID(s) associated with the stream(s) that it can process and decodes the TS packets. The present invention is applicable to a transmitter and a receiver that perform encoding and decoding.

摘要： This invention relates to an information providing system, a reproducing apparatus, a reproducing method, an information providing apparatus, an information providing method, a recording medium, and a program. If an instruction is given to download a Japanese language audio file, update files corresponding to the content recorded on an optical disc 11 are downloaded. After being downloaded as the update files, audio stream files in Japanese are recorded to a local storage 12 along with accompanying clip information files, play list files for controlling reproduction of the audio stream files, and an updated navigation program file. The updated navigation program is used illustratively to reproduce a clip 3 audio stream file in Japanese. This invention applies among others to players to which a recording medium that stores contents is removable.

摘要： A picture decoding method and apparatus for encoding a video signal. The method includes performing an encoding process on the video signal to generate a bit stream compatible with MPEG 1 moving picture video standard. The method further includes controlling the encoding process so as to generate the bit stream which includes, in a previous picture header, an extension start code indicating the beginning of extension data added when a picture header includes control data that is newly added in MPEG 2 standard format and the extension data, and does not include, in a current picture header, the extension start code and the extension data.

摘要： A picture decoding method and apparatus for decoding a bit stream, the bit stream being compatible with MPEG 1 moving picture video standard. The method includes receiving, via an input terminal, from the bit stream that includes extension data added in a header of a picture layer of the bit stream when the header includes control data newly added in MPEG 2 standard format, a picture coding type and the extension data of an anterior header of the picture layer. The bit stream in the picture layer is decoded using the picture coding type and the extension data of an anterior header of the picture layer when an extension start code indicating the beginning of the extension data of the current header is not received from the bit stream.

摘要： For a BD-ROM, a picture-in-picture function and a wallpaper display function are accomplished. A second video plane 50 for displaying a moving picture is added to planes 10, 11, and 12 for displaying a moving picture, a subtitle, and graphics, respectively. One of the outputs of the second video plane 50 and the video plane 10 is selected by a switch 51 on a pixel-by-pixel basis. Reduced moving picture data are stored on the second video plane 50. The switch 51 is controlled according to a display position of the reduced moving picture data on a pixel-by-pixel basis. As a result, reduced moving picture data of the second video plane 50 are displayed as a sub screen against the moving picture data of the video plane 10. When wallpaper picture data instead of the moving picture data are stored on the video plane 10, a display screen is obtained as if a wallpaper were displayed in the background of the reduced moving picture data.

摘要： The present invention facilitates reading in advance information on addresses where data of each reproduction path to be reproduced is stored. Clip AV stream 1 to Clip AV stream 3 of angles forming a multiangle are managed by PlayList#1 to PlayList#3 for the different angles. Each of PlayList#1 to PlayList#3 is divided by angle change points. Each of the divided reproducing sections corresponds to a PlayItem. Correspondences between source packet numbers and presentation time stamps of the angle change points are recorded in an EP_map. The present invention is applicable to DVD recording and reproducing apparatus, for example.
