  FIG. 6 is a flowchart showing a processing operation for notifying the content to be erased in the image recording / reproducing apparatus 1. The central control unit 10 performs the following operation process by executing the notification control program 5j. When it is determined that the content is recorded in the recording unit 4, in step a0, a process for notifying the content is started, and the process proceeds to step a1.

  In step a1, the central controller 10 determines whether or not notification setting information indicating that notification of content that is due to be deleted is not stored in the notification information storage unit 6e. If it is determined in step a1 that notification setting information indicating no notification is not stored, the process proceeds to step a2.

  In step a2, the central control unit 10 determines whether or not the notification time is stored in the notification information storage unit 6e. If it is determined in step a2 that the notification time is stored, the process proceeds to step a3.

  In step a <b> 3, the central control unit 10 determines whether or not the notification time is reached in the notification information storage unit 6 e based on the timing information of the timing unit 8. If it is determined in step a3 that the notification time has come, the process proceeds to step a4.

  In step a4, the central control unit 10 determines the content to be erased and generates notification information. Detailed processing of step a4 will be described later. When the process of step a4 is completed, the process proceeds to step a5.

  In step a5, the central control unit 10 controls the communication unit 9 to transmit the notification information generated in step a4 to a predetermined notification destination stored in the notification destination storage unit 6f, and proceeds to step a6. End the process. When the process ends in step a6 until the supply of power to the image recording / reproducing apparatus 1 is stopped, the process proceeds to step a1.

  If it is determined in step a1 that notification setting information indicating no notification is stored, the process proceeds to step a6.

  If it is determined in step a2 that the notification time is not stored, the process proceeds to step a7.

  In step a7, the central control unit 10 determines whether there is content to be erased based on the timing information of the timing unit 8 and the index data recording unit 4 of the recording unit 4. In step a7, the content that is two hours before the deletion deadline is set as the content to be deleted. If it is determined in step a7 that there is content to be deleted, the process proceeds to step a8.

  In step a8, the central control unit 10 generates notification information. The notification information generated in step a8 includes a content title, an erasure period, a thumbnail image of the content, a change instruction information for changing the erasure period, and a reproduction instruction information for transmitting the content. When the process of step a8 is completed, the process proceeds to step a9.

  In step a9, the central control unit 10 controls the communication unit 9 to transmit the notification information generated in step a8 to a predetermined notification destination stored in the notification destination storage unit 6f, and proceeds to step a2.

  As described above, content whose predetermined time has elapsed from the recording date and time is set as an erasure target. Therefore, the recorded content can be set as the erasing target in order from the oldest recording date and time. Of the contents recorded in the recording means, the one with the new recording date / time is more likely to have not been viewed by the user than the one with the old recording date / time. The content can be erased efficiently, and a recordable recording capacity in the recording unit 4 can be secured.

  The operation process shown in FIG. 6 can be terminated by stopping the supply of power to the image recording / reproducing apparatus 1. The process of step a4 may be performed before the process of step a3. In this case, the notification list information is generated a predetermined time before the notification time.

  FIG. 7 is a flowchart showing the process for generating the notification information in step a4 described above. When the process proceeds from step a3 to step a4 in the flowchart shown in FIG. 6, the process proceeds from step b0 to step b1. In step b1, the central control unit 10 sets a predetermined number “i” to zero (0), that is, i = 0, and proceeds to step b2.

In step b2, the central control unit 10 sets i = i + 1 and proceeds to step b3.
In step b3, the central control unit 10 determines whether i is smaller than the value obtained by adding “1” to the number of contents “I” recorded in the recording unit 4, that is, whether i <I + 1. Judging. If it is determined in step b3 that i <I + 1, the process proceeds to step b4.

  In step b4, the central control unit 10 determines whether or not the reproduction state of the content that is the recorded program having the recording number i is not reproduced, based on the index data stored in the index data storage unit 4b. If it is determined in step b4 that the reproduction state of the content with the recording number i is not yet reproduced, the process proceeds to step b5, and if it is determined that the reproduction state of the content with the recording number i is not yet reproduced, the process proceeds to step b2.

  In step b5, the central control unit 10 deletes the expiration date of the content with the recording number i based on the index data stored in the index data storage unit 4b and the notification content selection condition stored in the notification information storage unit 6e. Determines whether it is between date A and date B. Date / time A is start point information, and date / time B is end point information. In step b5, if the deletion period of the content with the recording number i is between date A and date B, the process proceeds to step b6, and in addition to the notification program list, the process proceeds to step b2.

  When there are a plurality of contents that have an erasure period between the date and time A to the date and time B, notification information representing a plurality of contents to be erased is generated by performing such processing. This notification information includes a content title, an erasure period, a thumbnail image of the content, a change instruction information for changing the erasure period, and a reproduction instruction information for transmitting the content.

  As described above, here, the central control unit 10 determines the content to be erased with respect to the content that has not been reproduced. There is a possibility that the content that has not been reproduced has forgotten that the user has recorded it in the recording unit. By making such content to be erased, the user can recognize that there is unplayed content in the recording unit, and the user can record from the time the content is recorded until it is erased. The content recorded in the section can be recognized.

  Further, as described above, when the notification time is stored in the notification information storage unit 6e, the deletion information indicating the contents to be deleted is not transmitted one by one, but transmitted all at once. Notification can be performed, and the load of transmission processing by the communication unit 9 can be reduced. Further, since notification information representing contents to be erased is collectively notified at a predetermined time, it is possible for the user to save the trouble of receiving each piece of erase information corresponding to each content. Is improved. For example, when the transmission time information stored in the notification information storage unit 6e is 12:00 and the selection condition of the notification content is 14:00 (14:00) on the current day to 14:00 on the next day, it is shown in Table 1. Based on the index data, the central control unit 10 generates notification information with the contents of the recording numbers 1 and 4 as erasure targets.

  8 and 9 are diagrams showing the notification information displayed on the terminal display unit 55 of the mobile phone device 28. FIG. In the mobile phone device 28, the notification information transmitted to the e-mail address which is a predetermined notification destination is received by the terminal wireless communication unit 51 via the wireless base station and the antenna unit 52. FIG. 8 is a diagram when the notification information generated in step a4 of FIG. 6 described above is displayed. Here, a case where two contents are to be erased is shown. FIG. 9 is a diagram when the notification information generated in step a8 of FIG. 6 described above is displayed. The notification information received by the terminal wireless communication unit 51 is displayed on the terminal display unit 55 by the terminal control unit 56. The terminal display unit 55 displays the phrase “The following recorded program will be deleted.” And also displays the title of the content to be deleted, the deletion deadline, and the thumbnail image. Furthermore, in response to the notification information representing each content, the terminal display unit 55 transmits command information for changing the erasure deadline of the content to be erased (hereinafter sometimes referred to as a change command). A “change” button and a “play” button for transmitting command information for receiving the content to be erased (hereinafter also referred to as a playback command) are displayed. As shown in FIGS. 8 and 9, the notification information is generated so that the terminal control unit 56 causes the terminal display unit 55 to display the thumbnail image together with the character information such as the title of the content and the deletion deadline. The thumbnail image is displayed in the thumbnail image display area 61. The thumbnail image display area 61 is arranged below the character display area 62 where the title and erasure period of the content are displayed when the notification information is displayed on the terminal display unit 55, and the title, erasure period and thumbnail of one content are displayed. The image is displayed in association with it. By setting a predetermined notification destination for a communication device frequently used by a user such as the mobile phone device 28, the user can easily know the notification information as described above. Therefore, it is possible to notify the information on the content to be deleted to the user at the remote place, and to reduce the content from being deleted without the user's knowledge. In addition, since the content title and erasure time limit and the thumbnail image are displayed in association with each other on the terminal display unit 55, the user can easily grasp the content of the content to be erased.

  The “change” button corresponds to URL information. When the “change” button is selected and determined, information corresponding to a predetermined URL can be received. Here, the deletion deadline change menu information for changing the deletion deadline of the content to be deleted is acquired. The change menu information of the erasure period is stored in the notification information storage unit 6e.

  FIG. 10 is a diagram showing an erasure period change menu 65 displayed on the terminal display unit 55 of the mobile phone device 28. In the deletion deadline change menu 65, the program name, channel, reproduction state, program content, and deletion deadline are displayed. In FIG. 10, when the notification information shown in FIG. 9 is displayed on the terminal display unit 55, the deletion period displayed on the terminal display unit 55 when the “change” button corresponding to the program A is selected and determined. It is a figure which shows the change menu. The erasure period is displayed including input boxes 66A to 66D representing “year”, “month”, “day”, and “time”, respectively. In each of the input boxes 66A to 66D, the expiration date recorded in the current index data recording unit 4b is displayed, and information in these input boxes 66A to 66D is changed by an input operation by the terminal command input unit 7. Can do.

  A selection box for prohibiting erasure of contents is displayed below the erasure time change menu 65. When it is not desired to delete the content to be deleted, the content, that is, the recorded program, is marked by selecting and determining the selection box 67 for prohibiting deletion of the recorded program.

  When the “change execution” button 68 displayed on the erasure period change menu 65 is selected and determined, the input information is transmitted to the image recording / playback apparatus 1 via the Internet 25, and the information is stored in the image recording / playback apparatus 1. If the erasure time limit is received by the communication unit 9 of the playback device 1 and the erasure time limit has been changed, the central control unit 10 changes the erasure time period recorded in the index data recording unit 4 and prohibits erasure of content. Is selected, the central control unit 10 invalidates the erasure period recorded in the index data recording unit 4. When the “change execution” button 68 is selected and determined, the notification information as shown in FIGS. 8 and 9 is displayed again on the terminal display unit 55 of the mobile phone device 28. Thus, a communication device such as a mobile phone device 28 that can receive notification information transmitted to a predetermined notification destination even when the user is not near the image recording / reproducing apparatus 1 and is out of the office, for example. In this case, it is possible to change the content erasure deadline, extend the content erasure deadline that the user does not want to erase, or prohibit erasure, thereby further improving convenience.

  FIG. 11 is a flowchart showing an operation process related to the notification information in the mobile phone device 28. In the cellular phone device 28, when the power is turned on, the process proceeds from step c0 to step c1, and in step c1, the terminal control unit 56 determines whether or not the terminal wireless communication unit 51 has acquired the notification information. In step c1, if the terminal control unit 56 determines that the terminal wireless communication unit 51 has acquired the notification information, the terminal control unit 56 proceeds to step c2, and if it determines that the notification information has not been acquired, repeats step c1.

  In step c2, the terminal control unit 56 acquires notification information from the terminal wireless communication unit 51, displays the acquired notification information on the terminal display unit 55 as shown in FIGS. 9 and 10, and proceeds to step c3. .

  When the central control unit 10 determines in the above-described step d3 that the erasure period is not changed, the process proceeds to step d5.

  In the present embodiment, an erasure deadline indicating the date and time when content is erased is used as management information. However, in other embodiments of the present invention, management information is subject to erasure before the content is erased. The notification time information indicating the date and time when the content is notified may be used, and the management information may be recording date and time information indicating the date and time when the content is recorded. When the notification time information is used as the management information, the central control unit 10 generates notification information with the content that has reached the notification time as an erasure target, transmits the notification information to a predetermined notification destination, and starts from the notification time in advance. After a predetermined time elapses, the recording unit 4 is controlled so as to erase the content related to the notification time. When the recording date / time is used as the management information, the central control unit 10 sets the recording unit 4 to delete the content that has passed a predetermined time from the recording date / time, and delete the content that has passed the predetermined time. Control. As described above, the management information only needs to include at least one of content recording time information, content erasure time limit information, and content notification time limit information.

  In the present embodiment, the number of thumbnail images representing the contents is one per content. However, in still another embodiment of the present invention, there are a plurality of thumbnail images representing the contents. There may be. If there are a plurality of thumbnail images representing the contents of each content, it becomes easier for the user to understand the contents.

  In the present embodiment, the communication device including the mobile phone device 28 that has received the notification information may be configured to give the change command and the playback command to the image recording / playback device 1 by e-mail after receiving the notification information. The image recording / reproducing apparatus 1 has an e-mail server function for receiving an e-mail, and the central control unit 10 controls the recording unit 4 and the communication unit 9 based on a change instruction and a reproduction instruction included in the received e-mail. By doing so, the same effect can be obtained.

  FIG. 13 is a diagram showing a preference information setting menu 71 displayed on the display device 21. The central control unit 10 displays the preference information setting menu 71 shown in FIG. 13 on the display device 21 by executing the preference data setting program 5g. The user uses the remote control 22 to display a genre, an input box corresponding to each genre, and a “setting” button in the preference information setting menu 71, and select an input box provided corresponding to each genre. And selecting the “set” button to generate preference data based on the preference information input by the user, and the preference data storage unit of the data memory 6 Register in 6d. Here, the preference information represents a user's favorite genre.

  In the embodiment of the present invention, the central control unit 10 records, in the index data, the date and time after the elapse of a period determined from the recording end time of the content as the erasure period. In another embodiment of the present invention, In addition, the content erasure period may be determined.

  FIG. 14 is a flowchart showing an operation process for determining the content erasure deadline. When the content is reserved for recording, the central control unit 10 moves from step e0 to step e1 by executing the recording reservation control program. In step e1, the central control unit 10 is the same as the content reserved for recording. It is determined whether or not an expiration date for the series contents is set. The same series means the same title and at least a part of the title. If the central control unit 10 determines in step e1 that the content in the same series has no erasure time limit, the process proceeds to step e2.

  In step e2, the central control unit 10 determines whether or not the genre of the content to be reserved for recording is a genre registered as preference information stored in the preference data storage unit 6d. When the central control unit 10 determines in step e2 that the genre of the content reserved for recording is registered as the preference information stored in the preference data storage unit 6d, the process proceeds to step e3.

  In step e3, the first erasure grace time is added to the recording date and time of the content to be reserved for recording to determine the erasure time limit, and the process proceeds to step e4, where the processing ends.

  If it is determined in step e2 that the genre of the content reserved for recording is not registered as the preference information stored in the preference data storage unit 6d, the process proceeds to step e5.

  In step e5, the second erasure grace time is added to the recording date and time to determine the erasure time limit, and the process proceeds to step e4.

  The first erasure grace time is selected as a time longer than the second erasure grace time, for example, twice as long as the second erase grace time. The second erasure window is selected, for example, for one week, and the first erasure window is selected, for example, for two weeks. The first erasure grace period and the second erasure grace period can be set by the user operating the remote controller 22.

  As described above, in the image recording / playback apparatus 1 according to the present embodiment, it is possible to change the erasure time limit for erasing content based on the user's preference information. Since the period can be lengthened, convenience is further improved.

  If the central control unit 10 determines in step e1 that the content in the same series has an erasure period, the process proceeds to step e4. As a result, it is possible to prevent the content of the same series from being erased without setting the expiration date.

  In still another embodiment of the present invention, when the notification information is transmitted at a predetermined time in the image recording / reproducing apparatus 1 described above, the time of the content (program) to be deleted and the recording information are recorded in the notification information. Information indicating the recording capacity of the content recorded in the section 4 and the time to be secured based on the recording capacity required for recording the content reserved for recording until the next notification information notification time May be included. The time to be secured indicates the time of the content that needs to be erased from the already recorded content in order to record the reserved content. When generating the notification information, the central control unit 10 records the recording capacity of the content (program) recorded in the recording unit 4 and the content reserved for recording until the next notification information notification time. The time to be secured is calculated on the basis of the recording capacity necessary for this.

  FIG. 15 is a diagram showing notification information to which information indicating content time and time to be secured is added and displayed on the terminal display unit 55 of the mobile phone device 28. In the mobile phone device 28, the notification information transmitted to the e-mail address which is a predetermined notification destination is received by the terminal wireless communication unit 51 via the wireless base station and the antenna unit 52.

The notification information received by the terminal wireless communication unit 51 is displayed on the terminal display unit 55 by the terminal control unit 56. The terminal display unit 55 displays the phrase “The following recorded program will be deleted.” In addition to the title, deletion deadline, and thumbnail image of the content to be deleted, the content time, The time to be secured is displayed. Further, in response to the notification information representing each content, the terminal display unit 55 includes a “change” button which is command information for changing the erasure deadline of the content to be erased, and the content to be erased. A “play” button, which is command information for reception, is displayed. As shown in FIG. 15, the notification information is generated so that the terminal control unit 56 causes the terminal display unit 55 to display a thumbnail image together with character information such as a content title and an expiration date.

  In this way, by notifying how much time is required for recording in order to record the reserved content, the user can select the reserved content and the already recorded content. It is possible to select which one is preferentially recorded. For example, if the user cannot record all of the reserved content by postponing or prohibiting the deletion of the content to be deleted, the reserved content that is close in time The central control unit 10 controls the recording unit 4 so as not to perform recording by reservation at the time when the recording becomes impossible in order and the content cannot be recorded.

  FIG. 16 is a flowchart showing a processing operation for notifying content to be erased in an image recording / reproducing apparatus according to another embodiment of the present invention. The image recording / reproducing apparatus of the present embodiment has the same configuration as that of the image recording / reproducing apparatus 1 shown in FIG. 1 described above, and only the notification control program 5j is different, and thereby the process for notifying the content to be erased. The operation is different. Accordingly, like parts are denoted by like reference numerals, and the description thereof is omitted.

  In step f5, the central control unit 10 determines the content to be erased, generates first notification information, and proceeds to step f6. Detailed processing in step f5 will be described later.

  In step f6, even if the central control unit 10 erases all the contents to be erased included in the first notification information, it cannot record all of the reserved contents by the time notified next time. Determine whether or not. In step f6, even if all the contents (programs) to be deleted included in the first notification information are deleted, it is determined that not all the reserved programs can be recorded by the next notification time. If YES, go to step f7.

  In step f7, the central control unit 10 again determines the content to be erased and generates second notification information. Detailed processing of step f7 will be described later. When the process of step f7 is completed, the process proceeds to step f8.

  In step f8, the central control unit 10 records all the reserved programs by the next notification time even if all the contents to be deleted included in the first and second notification information are deleted. Determine if you can't. Even if all the contents to be deleted included in the first and second notification information are deleted in step f8, it is not possible to record all the contents (programs) reserved until the next notification time. If it is determined, step f9 follows.

  In step f9, the central control unit 10 again determines the content to be erased and generates the third notification information. Detailed processing of step f9 will be described later. When the process of step f9 is completed, the process proceeds to step f10.

  In step f10, the central control unit 10 controls the communication unit 9 to transmit all the generated notification information to a predetermined notification destination stored in the notification destination storage unit 6f, and proceeds to step f11. The process ends. When the process ends in step a6 until the supply of power to the image recording / reproducing apparatus 1 is stopped, the process proceeds to step a1.
