However, if there is an expansion slot in the slot of the property entry, or if there is a slot corresponding to another entry, the processing related to the slot of the property entry described below will be performed for these related slots. This is executed as a lump.
- an entry number (Entry Number) for specifying each slot is set.
- an entry property flag (Entry P roperty) is set.
- various kinds of information indicating attributes of each entry are set. One of the information is whether the slot corresponds to a folder (0: Folder) or a file.
- the entry property flag that identifies (l: File) is set.
- the property entry with the entry number 0 is assigned to the existing root folder 0 by the file management system of the optical disc 12, and! /
- the entry property flag is set to a value of 0 so that a folder can be identified.
- folders 1, 2, and files 3 and 4 immediately below this root folder property entries with entry numbers 1, 2, 3, and 4 are assigned, respectively, and the entry property flag has a value of 0 and a value of 0, respectively.
- Folder set to 1 so that it can be identified as a file! /
- property entries with entry numbers 5 and 6 are assigned, respectively, and the entry property flags are set to values 0 and 1, respectively.
- File 7 belonging to folder 5 a property entry with entry number 7 is assigned, and the entry property flag is set to a value of 1 to identify the file. It has been done.
- the property entry file E3 stores management information indicating a relationship with other entries in the nearest folder to which the corresponding file or folder belongs.
- a parent entry number (Parent Entry Number) indicating the corresponding slot is assigned.
- the parent entry number (Parent Entry Number) is set to the value 0 for the entries of entry numbers 1 to 4, respectively. Folders 1 and 2 and files 3 and 4 with entry numbers 1 to 4 belong to the root folder.
- the parent entry number (Parent Entry Number) is set to a value of 1
- the parent entry number (Parent Entry Number) is set to a value of 5
- the parent entry number (Parent Entry Number) is set to a value of 5.
- the parent entry number (Parent Entry Number) is set to a value of 5.
- file 6 The file 7 indicates that it belongs to the folder 1, the folder 1, and the folder 5.
- a child entry number pointing from the upper side to the lower side is also registered, so that files belonging to a specific folder can be easily searched by this child entry number.
- the entry with entry number 0 has entry numbers 1, 2, 3, and 4 pointing to the entries of folders 1, 2, file 3, and 4 as child entry numbers, and entry number 1 Entry numbers 5 and 6 indicating the entries of folder 5 and file 6 are registered as child entry numbers, and entry number 5 is registered with the child entry number of entry number 7.
- each file can be managed according to the hierarchical structure existing in the file management system and further according to the virtual hierarchical structure.
- information indicating another entry related to the definition of such a hierarchical structure is referred to as hierarchical information.
- the MPU 3 described above with reference to FIG. 5 or FIG. 7 according to the startup of the power supply and the operation of the folder switch 14 according to the virtual hierarchical structure by setting the entries in the property entry file E3. Build a hierarchical structure.
- the MPU 3 sets hierarchical information so as to belong to the root folder, and registers an entry relating to the temporary in the index file.
- the hierarchical information is set so as to belong to the virtual folder by the entry relating to the temporary, and the entry by the folder of the moving image and the still image is registered in the index file. This creates an index file for managing the imaging results. Record and retain on Disk 1 and 2.
- the MPU 3 accesses the optical disk 12 via the media interface 10 when the power is turned on or when the optical disk 12 is loaded, reproduces the index file, and stores various management information in the built-in memory. Hold.
- the entry of the folder related to the recording of the latest imaging result currently recorded on the optical disk 12 is detected. Description of the text entry file related to this entry Or by registering an entry, the folder name of this folder is detected.
- the detected folder name is updated, the hierarchical information is set to belong to the virtual folder by the entry of the moving image and still image folder by the folder name according to the update, and the entry relating to the virtual folder is indexed by the index file. Register with. Also, the hierarchical information is set so as to belong to this folder, and the entry of the file relating to the imaging result is registered.
- the hierarchical information is set so as to belong to the virtual folder created in this way, and the files related to the imaging results are sequentially registered in the index file.
- the folder switch 14 When the folder switch 14 is operated by the user, similarly, the entry relating to the folder is registered in the index file, the hierarchical information is set so as to belong to this entry, and the file based on the imaging result is stored in the index file. To record.
- MPU 3 sets an entry so as to correspond to the hierarchical structure shown in FIG. 7, and processes the index file.
- a virtual hierarchical structure is displayed by analyzing the index file, and selection of a file to be played is accepted by a user's selection in this hierarchical structure. If the user instructs playback without selecting any file, the files recorded on the optical disc 12 are sequentially played back in the order of the recording order by the recording of the index file and provided to the user.
- a new folder is created on the recording medium in response to the operation of the folder switch, and the imaging result is recorded under the created folder. It is possible to easily create folders and manage files by reflecting the user's intention in creating folders.
- the file management based on the imaging result in the index file is a virtual hierarchical structure different from the actual hierarchical structure set on the optical disc 12, high compatibility with other recording / reproducing devices is provided. While recording the imaging results by defining the hierarchical structure on the optical disk 12, the application of this video disk device 1 A hierarchical structure can be suitably defined.
- the folder is created in the folder setting mode, and the imaging result is recorded, but the present invention is not limited to this.
- the mode switching may be omitted.
- the present invention is not limited to this, and the index file is not limited to this. Even when used, a folder may be created according to the existing hierarchical structure to record the imaging result.
- an index file is created by a so-called external reference format in which a source file and an excerpt ⁇ a file in which a blueprint is compiled are separated, but the present invention is not limited to this. Not limited to this, it can be widely applied to the case where an index file is created by a so-called internal reference format in which a source file and a file of excerpt information are combined into one file, and furthermore, a format other than QT file format is used. It can be widely applied to the creation of index files.
- the present invention can be applied to, for example, a video disk device.
