Image processing device, image processing method, and program

Update processing and the like of an index file relating to change of a hierarchical structure is performed. The index file is recorded in a recording medium with content files. The index file is generated based on attribute information of content files and folders including the content files. Content files and folders form a hierarchical structure in which the folders are in an upper hierarchy. In the index file, a prescribed number of entries (management information areas) corresponding to content files and folders, respectively, are provided. Second index information indicating second entries corresponding to folders or content files positioned in a lower hierarchy of folders in the upper hierarchy is provided at first entries corresponding to folders in the upper hierarchy in a list format. First index information indicating the first entries is provided at the second entries.

File processing apparatus, file processing method, program and recording medium

An information processing system includes: an imaging device including a first recording medium recording a content file, and a management information storage unit storing management information for managing the content file in the first recording medium; an information processing device including a second recording medium recording a predetermined content file; and a control unit controlling so as to detect difference information relating to the storage state of the content file recorded in the first recording medium, based on the results of comparing present management information stored in the management information storage unit, with past management information which has been recorded before the present management information and is management information of the point-in-time at which the content file in the first recording medium was saved to the second recording medium, and record, in the second recording medium, the content file in the first recording medium, based on the detected difference information.

Imaging device, information processing device, information processing system, recording control method thereof, and program for causing a computer to execute the method

On a recording medium, there are recorded content files and an index file. The index file is constituted by attribute information of the content files (title text data, thumbnail-image data or the like). In the case of changing (recording or deleting) the content file, the index file is updated after the change. A computer sets up, in a nonvolatile memory, status information indicative of being in a predetermined process stage, during the predetermined process stage from a start of changing the content file to a termination of updating the index file. The computer, at turning on power, determines the matching/mismatching between the content and index files recorded on the recording medium utilizing the status information, thus repairing the index file as required.

Information processing apparatus, information processing method, and program

The present invention relates to a recording apparatus and a method, a playback apparatus and a method, a recording medium, and a program capable of quickly playing back a picture associated with a unit in which a moving image is encoded. An extraction sectionextracts one picture from each GOP. A number-of-pixels conversion sectionreduces the amount of information of the extracted picture by thinning out pixels. A static-image compression sectionencodes the picture whose amount of information has been reduced by a JPEG technique. A microcomputerassociates the encoded picture with the GOP from which the picture has been extracted and controls recording of the picture associated with the GOP onto a diskon which the moving image is to be recorded. The present invention can be applied to a recording apparatus for recording a moving image onto a data recording medium.

An information recording apparatus recording contents on a recording medium and managing the contents by using a content management file includes a control unit that checks a recording state of the recording medium loaded in the information recording apparatus to determine how to set up the content management file to be recorded on the recording medium and recording means for recording the content management file on the recording medium. The control unit determines the file setup of the content management file on the basis of the recording capacity of an area where the contents can be recorded on the recording medium. The recording means records the content management file in accordance with the file setup on the recording medium.

An optical disc drive is disclosed in which an optical disc on which pregrooves are formed for affording wobble signals frequency modulated by predetermined data signals is driven at a constant linear velocity. Until the time that the data signals obtained upon demodulating the wobble signals are taken out correctly, the reproduced wobble signals are compared with a predetermined reference signal so that a spindle motor for rotating the optical disc is controlled so as to be driven at an approximately constant linear velocity. After it is detected that the data signals obtained upon demodulating the wobble signals are taken out correctly, the spindle motor is driven in a controlled manner on the basis of data signals obtained upon demodulating the reproduced wobble signals so that the spindle motor is controlled so as to be driven at a constant linear velocity. In this manner, the optical disc is controlled immediately at the start time of the optical disc or at the time of track jump by the optical head so that the optical disc is driven a constant linear velocity.
