3 receives an event of a change in the operation state of the D-VTR,
Executed when the operation state is stopped and changed from reproduction to stop.

First, the recording information of the recording No. corresponding to the recording being reproduced is obtained (S402), and it is determined whether the recording is to be deleted (S403). If it is a deletion target, the recording / reproducing device connected via the network is controlled via the VTR control means 125 to delete the recording. That is, the current absolute position of the tape is acquired (S403), the value is compared with the recording start position, and the tape is rewound or fast-forwarded to the recording start position to perform cueing (S405). When the cueing is completed, the recording is deleted up to the recording end position (S4
06), the recording information is deleted from the recording information recording means 131 (S407), and the process ends.

Whether or not the reproduced recorded program is to be deleted is determined based on the deletion information and the reproduction index. FIG. 8 shows an example of the deletion information. For example, post-playback deletion processing (value 1) to delete after the end of reproduction, deletion processing to delete in deletion execution processing (value 2), protection processing to protect from deletion (value 3), and unset processing to perform no deletion or protection (Value 0). The post-playback deletion process deletes the recorded video if it has been reproduced. Whether playback has been completed is determined by the playback index. For example, it is assumed that a reproduction index of less than 75% has been reproduced. The protection process also rejects a deletion request from a user and protects the user from being deleted. The deletion process is performed when there is a deletion request from the user irrespective of whether the reproduction has been completed or when a predetermined condition is satisfied. The predetermined condition is a condition such as 30 days after recording. If not set, neither delete nor protect.

Referring to the flowchart of FIG. 5, a description will be given of a process for notifying a user of deletion of a recording before deleting the recording in the recording deletion processing in the recording management unit 13 according to the embodiment of the present invention.

After notifying the deletion of the recording, it is determined whether or not the cancel is pressed down (S503). When the cancel is not depressed, it is determined whether or not a predetermined time has elapsed, and the execution of the deletion is waited (S504). Is displayed (S506), and after the deletion process described with reference to FIG. 4 is executed (S507), the icon is deleted (S508), and the process ends.

In the monitoring process in step S503, if the cancel button is pressed within a predetermined display time (: YES), an icon for canceling recording deletion is displayed (S505), and the icon is deleted and deleted. Do not process.

An execution request deletion process in which the user calls the deletion user interface in the recording management unit 13 according to the embodiment of the present invention and processes recording by a request will be described with reference to the flowchart of FIG. FIG.
Is an example of a delete user interface displayed on the monitor.

02) Move the cursor to the position of the deletion information of the recording to be deleted with the up, down, left, and right keys of the remote controller, and set the deletion information to be deleted. After setting all the deletion information of the recordings to be deleted to be deleted, when the delete execution button is pressed (the recording button is pressed in the example of the user interface in FIG. 9), the deletion processing is started (S603).

The recording management means 13 first confirms whether there is a recording to be deleted (S604), and then specifies the device that has recorded the program from the recording information of the recording to be deleted. It is confirmed whether or not the device has a recording medium on which the program to be deleted is recorded (S60).
5). If it does not, stop the processing because there is a risk of inconsistency. If yes, the program content deletion process described with reference to FIG. 4 is executed (S606). After the deletion, the process returns to step S604, and the process returns to step S6 until there are no more recordings to be deleted.
05, the processing of S606 is repeated.

As described above, according to the present invention, the recording information is managed, and the recording is deleted at the end of the reproduction, so that it is possible to prevent the medium on which the watched program is recorded from being accumulated. Furthermore,
