A recording apparatus, a reproduction apparatus and a file management method are disclosed wherein, even if one of files recorded on a recording medium cannot be reproduced regularly, another file selected by the user can be reproduced normally. A file having a hierarchical structure formed from video data and audio data both in the form of compressed data together with information necessary for processing of the video data and audio data is produced and recorded on a predetermined recording medium. Upon production of the file, information regarding decoding of the video data and audio data is disposed collectively on the top side of the file.

Recording apparatus, reproduction apparatus and file management method

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

A recording apparatus, a reproduction apparatus, and a file management method are disclosed wherein the operability in management of a large number of files recorded on a recording medium using an index file can be improved significantly further than ever. An index file is formed from a series of entries of extract information from a large number of files. Information indicative of a relationship between the files is set to the index file. The index file is used to manage a large number of files and so forth recorded on a recording medium.

Recording apparatus, reproduction apparatus, and file management method

To search image information regarding image data, recorded on a storage medium, based on a desired search condition and to perform efficient display. An attribute-information obtaining sectionobtains attributes. For respective chapters, the attributes are held by an attribute file. A condition searching sectionsearches the attributes for the respective chapters in accordance with a condition input from a condition inputting section. A thumbnail obtaining sectionobtains thumbnails that match the search condition. An index displaying sectiondisplays the obtained thumbnails. When a thumbnail is selected via an image selecting section, an image reproducing sectionreproduces image data in accordance with link information extracted by a link-information extracting section

Image-information recording device and image-information display device

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.

Information recording apparatus and information recording method

The present invention is applied to an imaging device for recording, for example, a result of imaging on an optical disc by a QuickTime file format and forms an real data block by allocating management information for managing a specific region recorded by interleave processing, and the specific region is managed by the management information and a management information block.

File processing device, file processing method, program of file processing method, recording medium on which program of file processing method is recorded, and imaging device and recording medium on which file is recorded

A file recording apparatus receives input from a user in order to edit video data and to record a file based on a result of the edit. The file includes a block including management information, having at least a video track based on management information about the video data and an effect track based on management information about effects to be set for the video data in a hierarchical structure of management information for managing real data. The file also includes a block including real data, having at least real data associated with the effect track. The recording apparatus makes the effect track by setting a null effect having no advantage of the effect and an active effect having an advantage of the effect with regard to the video track, and makes the file by setting a source track as a target for the effect track to the video track.

The present invention provides an editing apparatus, a reproducing apparatus, and a recording medium for reproducing special effects by full use of the capabilities of the reproducing apparatus. The editing apparatus having original video data and edited data that are a collection of editing codes for performing an editing operation with a desired editing type on a desired portion in the original video data to generate edited video data includes a primary conversion table attaching means for attaching, to the editing video data, a primary conversion table for correlating at least the desired editing type with a standard editing type specified as standard in advance.

Providing edited video data suitable for efficient use of video reproducing device capabilities

The present invention is applied to a videodisc device for example, sets information necessary for reproducing a multiplexed stream, and information necessary for reproducing streams making up this multiplexed stream to one of blocks serving as management information, and assigns this multiplexed stream to the track corresponding to the block serving as this management information.
