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 section 221 obtains attributes. For respective chapters, the attributes are held by an attribute file 500. A condition searching section 223 searches the attributes for the respective chapters in accordance with a condition input from a condition inputting section 222. A thumbnail obtaining section 224 obtains thumbnails that match the search condition. An index displaying section 226 displays the obtained thumbnails. When a thumbnail is selected via an image selecting section 227, an image reproducing section 228 reproduces image data in accordance with link information extracted by a link-information extracting section 225.

摘要:
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.
摘要:
To perform update processing and the like of an index file relating to change of a hierarchical structure easily and rapidly.The index file is recorded in a recording medium 2 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.

摘要:
The occurrence of fragments is suppressed in an index file that manages individual contents files recorded on a recording medium. On an optical disk 2, a contents file and an index file that manages each of the contents files are recorded. The index file is formed of attribute information of each of the contents files (including text data of a title, thumbnail image data and so on). When a predetermined contents file is recorded on the optical disk 2, a microcomputer 19 updates an index file so as to register this predetermined contents file in the index file. In this case, the microcomputer 19 secures a predetermined number of continuous slots in fixed length in the index file, and allocates attribute information of this predetermined contents file to the slots. For example, a predetermined number is set to the maximum number of the slots, or to the average number of the slots to be predicted for use in order to register the contents file.
摘要:
Content files and an index file for managing the content files are recorded in a recording medium. The index file includes, for example, a text file FTX, a thumbnail picture file FTH, and a property file FP. The files each have continuous fixed-length slots. The fixed-length slots are each managed by a slot number (index information) indicative of the order of arrangement thereof. Each file has a predetermined number of management information areas including one or a plurality of continuous fixed-length slots. The management information areas are identified by the index information of the first fixed-length slot. A predetermined entry has a slot number for identifying another entry. The data on the other entry can be acquired by detecting the location of the other entry on the index file.
摘要:
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.
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.
摘要:
An optical disk stores a content file and an index file for managing the content file. A property file FP in the index file includes a file entry corresponding to the content file and a decode-information storage area (system information entry) in which decode information of the content file (AV profile entry) is stored. The file entry has pointer information (profile entry index) indicative of decode information of a corresponding content file stored in the decode-information storage area.
