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:
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.
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.

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:
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:
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.

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:
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.
摘要:
A reproduction apparatus reproduces view data including several tracks within a range of reproduction processing capacity. A reproduction apparatus for reproducing data from a recording medium having several tracks each used for recording image data and one or more pieces of edit data includes an input unit for inputting the data from the recording medium, an analysis unit for identifying the recording track type of the input data, a storage unit for storing a priority-level assignment table associating the track types with priority levels for a decoding process, and for storing a predetermined threshold value serving as a border between the priority levels for data to be reproduced and the priority levels for data not to be reproduced, a plurality of decode units each used for decoding a different type of data, and a priority-level determination unit for determining whether the input data is to be decoded based on the track type identified by the analysis unit, the priority level assigned to the input data and the threshold value, and for outputting the input data to one of the decode units selected in accordance with the type of the input data when decoding the input data.
摘要:
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.
