When playing back from the library (S51), the playback title must be set as described in the explanatory diagram of FIG. 7 (S52). . Thereafter, the disk identification information is obtained from the library information (S53), and it is determined whether the corresponding disk is inserted or whether the corresponding image information is stored in the HDD (S54). If the corresponding disc has not been inserted (S58), a message prompting insertion is displayed.

  When the disc is ready, the title identification information selected from the library information is acquired (S55), it is confirmed that the title exists on the disc (S56), and the reproduction process of this title is started (S57). . If there is no corresponding title, a message that no title exists may be displayed (S59).

  A desired image can be easily reproduced by directly designating and reproducing the content from the library displayed in this way.

(4) Manual Registration in Library Next, the operation when registering this library information by user operation will be described. FIG. 11 is a flowchart for explaining the operation when manually registering the library function library according to the present invention.

  Since the title recorded by the other device is not automatically registered in the library of the present device, when the user registers such title information manually (S61), the library information management unit 16- of the microcomputer block 16 is used. Under the control of 1, the title to be registered is set from the current disc (S62). Then, it is confirmed that the number of library information is not the upper limit (S63), and information such as a title is additionally registered in the library (S64). At this time, if the upper limit is exceeded, a message indicating that the library is full is displayed (S65).

  In this way, the user can manually register library information in the library, so it is possible to register titles recorded on other devices, such as registering all titles on a disc at once, and other useful information such as titles. By including the information, the library information can be made according to the specifications.

  The library information can be automatically registered to some extent for the disc number, date, day of the week, hour / minute, CH, etc., but it is preferable for the user to input the genre, title, etc.

(5) Manual Deletion from Library Next, a case where certain information is deleted from the library by a user's manual operation will be described. FIG. 12 is a flowchart for explaining the operation when the library function according to the present invention is manually deleted from the library.

  When the user manually operates, it is possible to delete from the library information what has become inconsistent with the actual disk or becomes unnecessary. That is, when performing the deletion operation (S71), a title to be deleted from the library is set under the control of the library information management unit 16-1 of the microcomputer block 16 (S72), and a deletion confirmation message is displayed (S72). S73). If it can be deleted, “OK” is set (S74), and deletion is executed from the library (S75).

  When a user manually deletes the disc, the disc is deleted on another device, the optical disc is lost, it is no longer needed, the library is full (the oldest is displayed as a candidate), etc. It is possible to delete information.

(6) Saving Library Next, a case where library information stored in the hard disk is saved in a removable medium such as an optical disk will be described. FIG. 13 is a flowchart for explaining the operation when saving the library of the library function according to the present invention.

  That is, the library information according to the present invention can be freely moved to an external optical disk or the like, and can be appropriately backed up. In the flowchart of FIG. 13, when the library is stored under the control of the library information management unit 16-1 of the microcomputer block 16 (S81), a save confirmation message is displayed (S82), and if consent is obtained (S83). ), It is confirmed that the DVD-RAM for storing the library information is inserted (S84). If the disc is not inserted, a message prompting the insertion is displayed (S86). If the disc is inserted, the library information is copied from the HDD to the DVD-RAM (S85).

  By such processing, the library on the HDD can be stored in the DVD-RAM. Therefore, for example, when the HDD fails, the library information can be restored later.

(7) Restoring Library Next, a case where the library information in the hard disk is restored based on the library information stored in the optical disk or the like will be described. FIG. 14 is a flowchart for explaining the operation when restoring a library having the library function according to the present invention.

  That is, in the flowchart shown in FIG. 14, when the library is restored under the control of the library information management unit 16-1 of the microcomputer block 16 (S91), it is confirmed that the restoration library information is on the DVD-RAM. Confirmation (S92) displays a message that library information does not exist if it does not exist (S96), and displays a restoration confirmation message if it exists (S93). If the approval is obtained (S94), the library information is copied from the DVD-RAM to the HDD (S94).

  As a result, the library on the DVD-RAM can be restored on the HDD, so that the library information can be restored even when the HDD fails.

(8) Automatic Registration in Library Next, a case where library information according to the present invention is automatically registered will be described. FIG. 15 is a flowchart for explaining the operation in the case of performing automatic registration in the library of the library function according to the present invention.

  The library information according to the present invention has been described earlier as including information registered manually in (4). However, the basic library information is automatically created after the recording process is completed, and is registered / registered. It will be preserved.

  As shown in the flowchart of FIG. 15, when the recording process is completed for a predetermined optical disk (S101), the library information is stored in the library information management unit 16- of the microcomputer block 16 after the recording end process (S102). Under the control of 1, after confirming whether the number of library information is the upper limit (S103), if the upper limit of the number of library information is reached, a message that the library is full is displayed (S105). If the upper limit is not reached, for example, as shown in (a) of FIG. 2, input from the user such as a disc number, recorded date, day of the week, hour, minute, and channel number is required. Information that is not to be registered is automatically registered (S104). Here, it is also preferable to extract some information from the thumbnail information and register it as library information.

  As a result, library information is automatically generated and added to the library when an object is generated upon completion of recording or the like, so that the user does not need to register each time.

(9) Automatic deletion from library Next, a case where the library information according to the present invention is automatically deleted will be described. FIG. 16 is a flowchart for explaining the operation when automatic deletion is performed from the library of the library function according to the present invention.

  In the library information, if the title is deleted from the disc, it is preferable that the corresponding title is deleted from the library in accordance with this and the library is updated in accordance with the current state.

  Therefore, in the flowchart shown in FIG. 16, the library title deletion process (S111) is performed. When the title deletion process in the optical disk is first performed (S112), the library information management unit 16 of the microcomputer block 16 is responded accordingly. Under the control of -1, it is confirmed whether or not the deleted title exists in the library in the hard disk (S113). If it does not exist, the deletion process is not performed, but if it exists, it is automatically deleted from the library (S114).

  As a result, when an object on the optical disk is deleted, the library information is automatically deleted from the library information, so that the user does not have to delete each object and the library is automatically updated according to the current image. .

(10) Automatic Correction of Library Next, the case where the library information according to the present invention is automatically corrected will be described. FIG. 17 is a flowchart for explaining the operation when the library of the library function according to the present invention is automatically corrected.

  In the library information, if the title name in the disc is corrected, the corresponding title in the library is corrected accordingly, and the library is preferably updated according to the current situation.

  Accordingly, in the flowchart shown in FIG. 17, this library title correction processing (S121) is performed first when the title in the optical disk is corrected (S122), and accordingly, the library information management unit 16 of the microcomputer block 16 corresponds to this. Under the control of -1, it is confirmed whether the corrected title exists in the library in the hard disk (S123). If it does not exist, the correction process is not performed, but if it exists, the title information in the corresponding library is automatically corrected (S124).

  Thus, since the library information is automatically changed when the object on the optical disk is changed, the user does not need to make corrections one by one, and the library is automatically updated according to the current image.
