摘要:
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.

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.

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.

Image information regarding image data recorded on a storage medium is efficiently recorded, regardless of a storage medium type. Thumbnail files 600 to 609 hold thumbnail slots 620 to 629, respectively. Each of the thumbnail slots 620 to 629 holds, as a thumbnail, a representative image of corresponding image data. Text files 700 to 709 hold text slots 720 to 729, respectively. Each of the text slots 720 to 729 holds text information regarding corresponding image data. An attribute file 509 holds an attribute file header 519 and an attribute slot 529. The thumbnail slots 620 to 629 and the text files 700 to 709 are referred to from the attribute slot 529.

This invention applies illustratively to the editing of taken pictures by use of a QT format file. An effect track ET is made by setting a null effect having no effect advantage and an active effect having an effect advantage with regard to a video track ST associated with video data management information. The QT format file is made by setting a source track ST as a target for the effect track ET to the video track ST.
摘要:
The present invention provides a file management apparatus for managing files, recorded on a recording medium, on the basis of an index file including management information about the files, the apparatus including: a management status information holding unit for holding management status information indicative of a management status of the files in the index file; a recording status detecting unit for detecting a recording status of the files recorded on the recording medium; and an inconsistency detecting unit for detecting an inconsistency between the management status of the files in the index file and the recording status of the files recorded on the recording medium on the basis of the management status information and the recording status detected by the recording status detecting unit.
