The present technology relates to a file processing device, a file processing method, and a program that enable efficient reproduction of a HEIF file. A high efficiency image file format (HEIF) file in which a related image associated with an image in the HEIF file is arranged in a top part of an mdat box is generated. Additionally, a top part of such a HEIF file is read. The present technology can be applied to generation and reproduction of a HEIF file.

File processing device, file processing method, and program

The present technology relates to a file processing device, a file processing method, and a program capable of reducing the number of images that the user loses. Restoration data for restoring a high efficiency image file format (HEIF) file storing a still image is written into the HEIF file. The HEIF file is restored using the restoration data. The present technology can be applied to processing of a HEIF file.

An information processing device, which includes: a data holding section which holds first time-series data of an operation parameter which varies through a predetermined capturing operation; a data comparing section which compares second time-series data of the operation parameter with the first time-series data, the second time-series data being correlated with a moving image recorded through an actual capturing operation and varying through the actual capturing operation; and a data area specifying section which specifies, among the second time-series data, a data area corresponding to the first time-series data on the basis of the comparison of the first and second time-series data.

Information processing device, information processing method and program

A recording apparatus and a recording method that can record both moving picture data and still picture data in a form reproducible by various reproducing apparatus. The moving picture data is compressed by an MPEG system by an MPEG encoder, formed into data for recording corresponding to a predetermined recording format by a format forming unit, and then recorded on a DVD. The still picture data is compressed by a JPEG system by a JPEG encoder, and recorded on the DVD separately from the moving picture data. In predetermined timing, the still picture data compressed by the JPEG system and recorded on the DVD is read, the still picture data is converted into I-pictures of the MPEG system by a format converting unit, and then the I-pictures of the MPEG system are recorded onto the DVD in the predetermined format via the format forming unit.

Recording device and recording method

A recording apparatus includes a screen information generation unit and a recording control unit. When again generating screen information of a recording medium recorded with plural image data, the screen information on which a screen for selecting the plural image data is based, and a recording state of the image data when the screen information was generated, the screen information generation unit selects a range of the screen information necessary to be rewritten in accordance with a recording state of image data in the recording medium when previous screen information was generated and a recording state of image data in the recording medium at a present time, and updates only the selected range of the screen information. The recording control unit records screen information generated by the screen information generation unit in the recording medium.

Recording apparatus and recording method

The present invention relates a recording apparatus and a recording method, a reproducing apparatus and a reproducing method, and a program that make it possible to easily judge whether data was recorded in a recording medium by an apparatus of own model. An own model/another model information generating unitgenerates, for each arbitrary recording unit, own model/another model information that is information indicating that the recording unit was recorded by an apparatus of own model. A discrimination code calculating unitsets VMGI and an effective management table TV as a continuous data sequence and sets a result of calculating a hash value of the data sequence as a discrimination code. A recording and reproducing apparatusrecords the discrimination code and the own model/another model information in a management table TV area of an optical disk. When a discrimination code' obtained by calculating the hash value and a discrimination code recorded in the optical diskcoincide with each other, the recording and reproducing apparatusreads out the own model/another model information. It is possible to apply the invention to a recording and reproducing apparatus.

Recording apparatus and recording method, reproducing apparatus and reproducing method, and program

A playback apparatus for playing back a moving image at a speed higher than a normal speed of the moving image on the basis of moving image data for displaying the moving image, the moving image data being coded by setting a predetermined number of images as a unit, is provided. The playback apparatus includes a storage section temporarily storing the obtained moving image data; a decoding section decoding the moving image data read from the storage section; a detection section detecting transfer rates; a storage control section controlling the storage of a number of the units; a selection section selecting one of the combinations from among the combinations indicated by the stored combination information in a predetermined procedure; an obtainment control section controlling the obtainment of the image data.

Playback apparatus, Playback method, recording medium, and program

A recording and playback apparatus for recording data on a recording medium that allows additional writing includes a recording device configured to record first data on the recording medium; a random-number generator configured to generate a random number; and a calculator configured to calculate a first identification code indicating that the first data has been recorded on the recording medium by the recording and playback apparatus, by applying a predetermined function to data included in the first data recorded on the recording medium by the recording device, the data including second data that changes on each recording on the recording medium by the recording device and including the random value generated by the random-value generator. The recording device further records the random value generated by the random-number generator and the first identification code calculated by the calculator so that the random value and the first identification code are included in the first data.

Recording and playback apparatus, recording and playback method, and program

A recorder operable to compress and code first image data of a moving image, and record the compressed and coded first image data on a data recording medium, including: an extracting mechanism operable to extract second image data to display a still image from the first image data of the moving image to be recorded on the data recording medium; a creating mechanism operable to create thumbnail image data to display a thumbnail image as an image smaller than the still image from the extracted second image data; and a storage-controlling mechanism operable to control a temporary storage of the created thumbnail image data.
