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.

Imaging device and control method

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. As a result, the user can perform a recording operation for the AV data without necessity of recognizing the restrictions that have been set to the reproduction list file and the attribute file.

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.

Data processing apparatus, data processing method, and computer program

An information processing apparatus includes a controller for controlling data recording to an information recording medium. The controller executes a state determination process of determining whether the information recording medium is ready to record additionally data. Upon determining that the information recording medium is not ready to additionally record the data, the controller performs a notification process of notifying that the information recording medium is not ready to record additionally the data.

Apparatus, method, and computer program for processing information

There is provided an information processing apparatus including a storage unit that stores content data, a movement instruction unit that provides instructions to move the content data stored in the storage unit in accordance with a user operation, a detection unit that detects characteristic information of the content data in accordance with movement instructions of the content data by the movement instruction unit, a basic interval setting unit that sets one or two or more basic intervals to the content data based on detection points of the characteristic information, and a data generation unit that generates content data for movement made of a plurality of the one or two or more basic intervals set by the basic interval setting unit.

Apparatus and method for enabling content data to be copied or moved in accordance with desired time or capacity of a storage medium and a program thereof

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.

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. Since the management information is stored in the nonvolatile memory, even if power is unexpectedly turned off, the management information will not be lost.

A data recording structure supporting an AVCHD format is provided. The data recording structure allows a playing process, an editing process and a write-once recording process to be quickly performed. When data recording is performed in a data recording format having a layered management structure such as an AVCHD format, identification information is stored in an index file containing index information for record data. The identification information is needed to perform one of the playing process on the record data, the editing process on the record data and the write-once recording process on data. This arrangement eliminates the need for reading a variety of files and retrieving information when one of the record data playing process, the record data editing process and the write-once recording process is performed. Each process is thus quickly performed.
