摘要:
The present technology relates to a device and a method for streaming distribution, a device and a method for streaming reception, a streaming system, a program, and a recording medium that can reduce a processing load relating to the display of subtitles in streaming. A streaming distributing device includes: a content fragment generating section configured to generate a fragment defined by an MP4 file format; and a subtitle fragment generating section configured to generate a fragment storing a TTML document instance relating to a subtitle to be displayed in the content, the fragment being defined by the MP4 file format, wherein instance classification distinguishing information for distinguishing whether the TTML document instance stored in the fragment is a TTML document instance specifying a rendering context relating to the subtitle is added to header information of the fragment.

The present technology relates to an information processing device and a method capable of adaptively providing a partial image of an image in each layer of an image constituted by a plurality of layers. The information processing device of the present technology generates a file that stores information on a whole of a base layer of encoded data produced by layer encoding of image data, information on each of partial areas of an image of the base layer, information on a whole of an enhancement layer of the encoded data, and information on each of partial areas of an image of the enhancement layer such that each of the information is stored in corresponding one of tracks different from each other. The present technology is applicable to an information processing device, an image processing device, an image encoding device, or an image decoding device, for example.

The invention can be applied to an optical disc drive, for example. In an index file of continuous entries by extracted information from a file, information indicating of the size of an objective file is set and management information on closely related files is registered collectively. Moreover, extracted video information is pointed by an entry pertaining to a disc title and the substitutional entry is registered. Furthermore, an entry of a related file is pointed and extracted information from each application is registered under management of the index file.

Entry property (2) contained in entry properties distinguishes normal and system from each other. The “normal” means real data entry while the “system” means an entry having description of a definition of a flag. The flag indicates file attribute information. The flag is defined by an apparatus or by a user. Entry property (3) distinguishes valid and invalid from each other for the entry. Entry property (4) indicates whether the file registered in the entry references another file. A referred counter indicates the number of files referencing the file. A referring file list indicates a reference origin when the file is referenced by another file. These information items enable description of reference relationship between the files.

A reproducer for reproducing video data including tracks in the range of reproduction capability. A reproducer (10) for reproducing data from a record medium having tracks on which image data and one or more pieces of edit data are recorded comprises input means (11) for reading data from record medium, analyzing means (12) for identifying the type of recording track on which input data is recorded, storage means (13) for storing priority list in which the type of a track is related to the decoding order and a predetermined threshold for determining upper to what number is reproduced, a plurality of decoding means (15, 16, 17) for decoding data, and judging means (14) for determining whether or not input data is to be decoded from the type of the track from the analyzing means (12) and from the priority list and the predetermined threshold stored in the storage means (13) and outputting, if the input data is determined to be decoded, the data to the decoding means (15, 16, 17) depending on the type of the data.

The present disclosure relates to an information processing apparatus and an information processing method that are capable of reproducing content on the basis of an edit list in the case where the reproduction start time of content contained in a file in the MP4 Fragmented Movie format is later than the reproduction start time in a movie time scale. An edit list generation unit registers a top position of content as a reproduction start position of the content and a predetermined value as a reproduction time duration of the content in an edit list when a reproduction start time of the content is later than a reproduction start time of the content on a movie time scale, the edit list associating the reproduction start position of the content with the reproduction time duration of the content reproduced from the reproduction start position. The present disclosure is applicable to a file generation apparatus that generates a Fragmented MP4 file, for example.

The present disclosure relates to an information processing apparatus and an information processing method that enable easy reproduction of audio data of a predetermined kind, of audio data of a plurality of kinds. A file generation device generates an audio file in which audio streams of a plurality of groups is divided into tracks for each one or more of the groups and arranged, and information related to the plurality of groups is arranged. The present disclosure can be applied to an information processing system configured from the file generation device that generates a file, a web server that records the file generated by the file generation device, and a moving image reproduction terminal that reproduces the file, for example.
