Abstract: The present technology relates to a file generation device, a file generation method, a file reproduction device, a file reproduction method, and a program capable of associating an image stored is a file with external data outside the file. A file control unit generates an association-type high efficiency image file format (HEIF) file in which an image in an HEIF file compliant with HEIF and specific information that specifies external data outside the HEIF file, the external data to be associated with the image, are stored in association with each other. Furthermore, the file control unit reproduces the association-type HEIF file. The present technology can be applied to a case where an HEIF file is generated or a case where the HEIF file is reproduced.

Abstract: The present technology relates to a data processing device, a data processing method, and a program that are enabled to easily perform simultaneous generation of a plurality of files in which file streams having different data formats are stored. From an identical image, file data is generated that is obtained by encoding the image and to be stored in each of a plurality of files. First file data stored in one file of the plurality of files and second file data stored in another one file are data different from each other in at least one of codec, chroma format, or bit depth. The present technology can be applied to generation of a plurality of files having the same image content.

Abstract: The present technology relates to a file processing device, a file processing method, and a program that achieve quick index display. A file control unit generates a proxy file storing a related image related to an image in a high efficiency image file format (HEIF) file, the proxy file being another HEIF file. Furthermore, the file control unit detects an image corresponding to a selected related image selected from related images stored in the proxy file. The present technology can be applied to, for example, a case where index display of thumbnail images is performed.

Abstract: The present technology relates to a file processing device, a file processing method, and a program that enable association of, for example, an image stored in a file with external data outside the file. A file control unit generates a high efficiency image file format (HEIF) file in which a reserved area is secured that is used to store relationship information related to association of an image stored in the HEIF file with specification information specifying external data that is outside the HEIF file and is to be associated with the image. Furthermore, the file control unit writes the relationship information into the HEIF file by using the reserved area. The present technology can be applied to, for example, a case where a HEIF file is generated and an image stored in the HEIF file is associated with external data later, and the like.

Abstract: To improve user-friendliness in recording AV data created after recording is started until it is stopped as a file. AV data that are created after recording is started until it is stopped are recorded as a file. Information that represents a reproduction region and mark information that represents a jump position are additionally written to a reproduction list file. At this point, it is determined whether or not restrictions that have been set to the reproduction list file and an attribute file for additional writing are satisfied on the basis of the reproduction list file as an additionally writable candidate and the attribute file that correlates reproduction time and address of the AV data. When having been determined that they be satisfied, the reproduction region information and the mark information are additionally written to the reproduction list file as the additionally writable candidate. When having been determined that they be not satisfied, a new reproduction list file is created.

Abstract: An information processing apparatus includes: a detecting section that detects feature information of at least one AV stream; a recording section that records the AV streams, clip information defining attributes including the detected feature information, and playback-segment data specifying at least one playback segment to a storage medium in accordance with a predetermined data-recording format, the playback-segment data being obtained by setting a playback start point and a playback end point with respect to the AV streams; a playback-segment setting section that sets the playback segments with respect to the AV streams on the basis of detection time point of the feature information; and a data generating section that generates the playback-segment data specifying the playback segments set by the playback-segment setting section.

Abstract: Non-destructive editing of a movie stream recorded with management information attached thereto according to a predetermined standard format is performed. First, an entry for desired content from among real play lists is added to a virtual play list. In the virtual play list, a playback content editing operation is performed. The process of editing a virtual play list that does not contain content of an entity involves non-destructive editing that does not accompany editing of the content of an entity. In addition, non-destructive editing of a virtual play list only requires the updating of a management information file, and only involves an increase in the used amount of the recording medium by the additional amount of the management information even if a playback section is copied, thus improving user convenience.

Abstract: A data processing apparatus which divides stream data into portions is disclosed. An evaluation value calculating section calculates an evaluation value at a dividing candidate position of the stream data based on an evaluation function. A comparing section compares the evaluation value calculated by the evaluation value calculating section with a predetermined threshold value. A dividing candidate position obtaining section obtains the dividing candidate position of the stream data in each predetermined unit. A controlling section decides a dividing position of the stream data based on a compared result of the comparing section. A controlling section causes the dividing candidate position obtaining section to obtain a second dividing candidate position when the compared result of the comparing section denotes that the evaluation value at the first dividing candidate position does not exceed the threshold value.

Abstract: Management information for video data and audio data that are created after their recording is started until it is stopped and that are recorded as a stream file on a record medium is more securely stored. When their recording is started, EP entry information contained in management information of the stream file is created. Whenever EP entry information is created, it is written to a nonvolatile memory. After their recording is stopped, fixed value information and so forth that are contained in the management information are created and written to the nonvolatile memory. According to a disc eject operation, the management information written to the nonvolatile memory is written to the disc and the contents stored in the nonvolatile memory are cleared. Likewise, when power is turned off without the eject operation, information stored in the nonvolatile memory is written to the disc.
