摘要： A format for accessing content such as a full-length move from an optical disc uses an XML description file stored on the disc to generate one or more screens that a user employs to access the content. The decoding requirements of a hardware or software player are reduced by discarding specific elements of an encoding standard such as MPEG4 that is used to encode the content on the disc. The maximum average and peak bitrates at which the data is transferred are limited to further reduce the demands on the player.

摘要： A format for accessing content such as a full-length movie from an optical disc uses an XML Description File stored on the disc to generate one or more screens that a user employs to access the content. To increase the efficiency of accessing data, data files that describe the content of the disc are located near the beginning of the video zone whereas larger data files, such as presentation files, are located at the end of the video zone. To reduce the possibility of incompatibilities between commands, a limited set of application program interface (API) commands is defined for use in an XML Description File. To maximize the vertical data recorded on the disc when the source aspect ratio is high, two, independent horizontal and vertical distortion factors are used. The audio and video tracks are interleaved into 1000 millisecond blocks and are demultiplexed by the application player during playback.
