    摘要: The present invention provides an information storage medium in which a stream including basic data and extension data for next generation is stored, so as to allow a decoder capable of decoding only basic data to process such a stream including basic data and extension data.Such information storage medium is an information storage medium on which an audio stream including a plurality of TS packets is stored, wherein each of the TS packets includes one of (a) a first packet including basic data, and (b) a second packet including extension data related to the basic data, the basic data is data capable of being decoded into complete sound without requiring the extension data, and the extension data is data intended for improving the quality of audio generated from the basic data, and a header of each of the TS packets includes an identifier indicating whether the TS packet includes the first packet or the second packet.

    摘要: Play list information is recorded on the local storage 200. The play list information contains main-path information and sub-path information. The main-path information specifies one among a plurality of AVClips as a MainClip and defines a main reproduction section for the MainClip. The sub-path information specifies another one among the plurality of AVClips as a SubClip and defines, for the SubClip, a sub reproduction section to be synchronized with the main reproduction section. On the local storage 200, an audio stream specified as the SubClip is recorded. The audio stream includes a plurality of PES packets which are each attached with a packet identifier (PID) that includes an upper field and a lower field. The upper field indicates that the audio stream containing the packet is a secondary audio stream whose reproduction output is able to be mixed with a reproduction output of the primary audio stream.

    摘要: After sizes of Intra pictures included in a digital stream are detected, an analysis unit 6 totals numbers of occurrences of the Intra pictures for each size to obtain an occurrence distribution of the sizes of the Intra pictures. Values “000b” to “111b” are respectively assigned to distribution ranges of the sizes of the Intra pictures. Then, an entry map, in which each Intra picture is represented by one of the values “001b” to “111b”, are to be recorded onto a recording medium in association with the assignment information.

    摘要: To provide means for editing a content data stream quickly. A data processor according to the present invention can edit a content that has been written on a medium. The content is stored in a file as a data stream including multiple packets of the same packet size. And a file system for accessing data on a cluster size basis has been established on the medium. The data processor includes: a receiving section, which receives an instruction on a partial deletion range including the beginning of the file; and a media control section for deleting data, the size of which is an integral number of times as large as the least common multiple of the cluster size and the packet size, from the beginning of the file within the partial deletion range.
