Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a distributed electronic mail, collected Web information, and other content content automatic deletion device and a recording medium recording a content automatic deletion program.
[0002]
[Prior art]
Conventionally, when a file is created, a valid period of the file is designated, and an expired file is automatically deleted.
Further, for example, the one described in Japanese Patent Laid-Open No. 9-305505 is based on the retention period and the number of received mails set in advance in the priority correspondence table corresponding to the mail source identifier. The emails accumulated above are automatically deleted.
[0003]
That is, according to the electronic mail automatic classification method, the mail reception subsystem compares the priority setting of the keyword / priority correspondence table file and stores the result in the mail classification file. The mail display subsystem searches the mail classification file, reads the corresponding mail from the mail reception file, and displays it. The mail statistical analysis subsystem updates the keyword / priority correspondence table file automatically based on mail statistical information and the keyword / priority maintenance subsystem manually by the user. Note that the mail erasing subsystem automatically erases mails that are out of a predetermined retention period and / or the number of received mails.
[0004]
[Problems to be solved by the invention]
However, when the e-mail is distributed or when the contents are collected, it is not always confirmed one by one, so each retention period cannot be specified.
Also, deciding the retention period uniformly according to the sender identifier is, for example, in the case of distributed news, there is a possibility of looking back in what has been read, and that there is no possibility of reading because it is old without reading And no difference in storage period appears.
[0005]
Therefore, the present invention reduces the inconvenience and prevents the content from being naturally stored so that the content is not excessively stored in a storage device, for example, at home, and the content overflows and eventually cannot be used effectively. It is an object of the present invention to provide a content automatic deletion device that can be deleted from a storage device and a recording medium that records a content automatic deletion program.
[0006]
[Means for Solving the Problems]
Automatic content deletion unit of the present invention comprises input means for inputting contents, and memorize means for storing the content that is the input, and output means for outputting the content, it said output means the content Control means for managing the output time and deleting the content based on the output time . The control means determines the storage period of the content according to the length of the output time, and deletes the content after the content reaches the storage period.
Further, the input means is a receiving means for receiving the content by communication, and the output means is a display means for displaying the content, so that the input means can be applied to an Internet communication device or a television receiving device.
[0007]
Further, the control means sets a storage period as a first period when the receiving means receives the content, and sets a storage period longer than the first period when the display means displays the content. And when the display means displays the content for a time longer than a predetermined time, the storage period is set to a third period longer than the second period, so that the display period depends on the presence or absence of display and the display time. Storage period.
[0008]
Further, the present invention causes a computer, input means for inputting the content and memorize means for storing the content that the input, output means for outputting the content, the time the content was output by the output means manage, on the basis of the output time, a computer-readable recording medium characterized by recording a program for controlling means, to function as to delete the content.

The content index 24 includes information such as a file name, a reception date / time, and a scheduled deletion date for a group of content.
A list of content names and reception dates and times in the content index 24 is displayed on the display device 5, and the user is allowed to select the content, and the selected content is read from the external storage device 3 to the content 25 in the memory 2. Is displayed on the display device 5.
[0011]
FIG. 2 is a flowchart for explaining the operation when receiving content. When receiving the content, the reception program 21 is operated to store the content received from the reception device 4 in the external storage device 3, and the file name, the reception date and time, the scheduled deletion date, etc. regarding the content are stored in the content index 24. It adds (step S11).
The scheduled deletion date is one week later. This one week is the default value. However, the value of one week is only an example.
[0012]
FIG. 3 is a flowchart for explaining the operation when a file is closed after viewing a certain content. The display program 22 includes a function for measuring the time during which content is displayed. If the measured time does not reach 1 minute in step S21, the scheduled deletion date of the content in the content index 24 is corrected to a date two weeks after that date (step S22).
If the measured time is 1 minute or longer, similarly, the scheduled deletion date is corrected to the day after 3 weeks (step S23). For example, the degree of looking at the table of contents or peeking a little is set to 1 minute. However, these numerical values are only examples.
[0013]
FIG. 4 is a flowchart for explaining the operation when the display program 22 is terminated after displaying some contents. In step S31, the scheduled deletion date for each content in the content index 24 is checked in order. It ends when there is nothing to check. If there is something to check, it is checked whether the date has reached the scheduled deletion date (step S32).
When the scheduled deletion date of the content has been reached or passed, the content is deleted from the external storage device 3 (step S33), and the index related to the content in the content index 24 is deleted (step S34). . If the scheduled content deletion date has not been reached, nothing is done and the process returns to step S31.
