  These units (evaluation value calculation unit 61, deletion candidate extraction / sort unit 62, list display processing unit 63, reservation unit 64, operation reception unit 65, deletion processing unit 66) are control programs that can be executed by the system control unit 6. Is stored in a memory (not shown), and is read from the memory and executed as necessary.

  In FIG. 1, when a recording list recorded in a recording medium 8 (hereinafter referred to as HDD 8) is displayed on the display 10 via the reproduction processing unit 4 and the reproduction output unit 5, the evaluation value calculation unit 61 An evaluation value is calculated for each content recorded in the HDD 8 based on operation information such as an operation time operated by the user on the list, and the evaluation value is held in a memory (not shown). A specific calculation example of the evaluation value by the evaluation value calculation unit 6 will be described with reference to FIGS.

  Based on the evaluation value calculated by the evaluation value calculation unit 61, the erasure candidate extraction / sorting unit 62 extracts erasure candidates from the recording list to create an erasure candidate list. Rearrange the display order of.

  The list display processing unit 63 performs display processing for presenting the deletion candidate list to the user based on the deletion candidate list created by the deletion candidate extraction / sorting unit 62. The erasure candidate list output from the list display processing unit 63 is displayed on the display 10 via the reproduction output unit 5.

  While the deletion candidate list is displayed on the display 10, the deletion processing unit 66 receives an deletion instruction by a user operation of the remote controller 10 or the like via the operation reception unit 65. Then, the erasure processing unit 66 outputs a control signal for erasing the content recorded in the HDD 8 to the content recording processing unit 7.

  2 and 3 are diagrams showing display examples when the content list recorded in the HDD 8 by the content recording processing unit 7 is displayed on the display 10 as a recording list. The recording list can be displayed on the screen when the user presses a “recording list” key provided on the remote controller 9.

  In FIG. 2, reference numeral 20 denotes a recording list. The recording list 20 includes a previous page feed key 21, a recorded content list 22, and a next page feed key 23. The recorded content list 22 of this example is a list display of 12 recorded content by thumbnail images. When there are 12 or less recorded contents, all are displayed on one page. When the number exceeds 12, it is displayed over a plurality of pages, and the user can move between pages of the recording list by operating the cursor key or the like of the remote controller 9 to view the recording list of the desired recording content. .

  As shown in FIG. 2A, when the user operates the cursor key of the remote controller 9 and places the cursor on the thumbnail image of the recorded content list 22, the moving image of the thumbnail image (title 2 in this case) on which the cursor hits. And the audio is reproduced in the thumbnail size. Further, when the user presses the “OK” key on the remote controller 9 with the cursor placed on the title 2, the title 2 can be reproduced. When the user places the cursor on the next page feed key 23 in the state where the titles 1 to 12 are displayed as the recorded contents in this way, as shown in FIG. 2B, twelve recorded contents on the next page are displayed. (Titles 13 to 24) are displayed.

  In FIG. 3, reference numeral 30 denotes a recording list. The recording list 30 includes a previous page feed key 31, a recorded content list 32, a detailed information display field 33, and a next page feed key 34. The recorded content list 32 of this example is a list display of nine recorded contents using the contents (title, recording date and time, recording time, etc.) of the recorded content as text information. When there are 9 or less recorded contents, all are displayed on only one page. When the number exceeds nine, it is displayed over a plurality of pages, and the user can move between pages of the recording list by operating the cursor key of the remote controller 9 to view the recording list of the desired recording content. .

  The number displayed on the left side of the recorded content list 32 is a serial number of the recorded content recorded in the HDD 8. In the example of FIG. 3A, among the recorded contents recorded in total 210, No. Nine recorded contents 73 to 81 are displayed on the screen. A state in which the cursor is placed on the display column of 74 recorded contents is shown. In the detailed information display field 33, the No. where the cursor is located is displayed. Detailed information of 74 recorded contents is displayed. The detailed information corresponds to the program information of the recorded content, and includes, for example, the title name of the program (formally without omission), the performer, and the program introduction. As in the example of FIG. 2, when the user presses the “OK” key on the remote controller 9 with the cursor placed on the title 2 (No. 74), the title 2 can be reproduced.

  The example shown in FIG. 3 (B) is the same as above, but moves to the next page of the recording list, and No. 81 and subsequent numbers. 82 to 90 indicate screen display states. As shown in FIG. 3A, when titles 1 to 9 (Nos. 73 to 81) are displayed as recorded contents and the user places the cursor on the next page feed key 34, FIG. As shown, nine titles 10 to 18 (Nos. 82 to 90) on the next page are displayed.

  A specific example of the evaluation value calculation method by the evaluation value calculation unit 61 in the recording / reproducing apparatus 1 configured as described above will be described below. In the following example, the case where an evaluation value is calculated for the recorded content in the recording list shown in FIG. 2 will be described. The larger the evaluation value, the higher the priority of deletion (to be deleted). Suppose there is.

  For example, as a first method, the evaluation value of the recorded content included in each page is calculated based on the display time of each page constituting the recording list. The evaluation value calculation unit 61 measures and holds the display time during which each page is displayed when the page of the recording list is switched according to the page switching operation of the recording list by the user. When the display time exceeds the set value, it is estimated that the page includes recorded content necessary for the user. Therefore, in this case, the evaluation value calculation unit 61 retains the evaluation value of the recorded content included in the page without adding it. On the other hand, if the display time does not exceed the set value, it is estimated that there is a high possibility that the page includes recorded content unnecessary for the user. Therefore, in this case, the evaluation value calculation unit 61 adds (for example, adds 1) the evaluation value of the recorded content included in the page and holds it.

  As a second method, based on whether or not the recorded content of the target page is selected and operated by the user while an arbitrary page of the recording list is being displayed (hereinafter, the displayed page is referred to as the target page), the recorded content The evaluation value of is calculated. This selection operation is to perform various operations by selecting a recorded content on the recording list, and includes, for example, an operation for shifting to an edit menu, a detailed information display operation, a reproduction operation, and the like. The evaluation value calculation unit 61 stores information indicating whether or not a selection operation has been performed for each recording content included in the target page and operation details (edit menu transfer operation, detailed information display operation, reproduction operation, etc.) in a memory (not shown). ). As information indicating whether or not this selection operation has been performed, for example, a selection operation flag may be given to the recorded content that has been selected and operated.

  In the above, it is presumed that the recorded content selected and operated by the user is highly likely to be a recorded content necessary for the user. Therefore, in this case, the evaluation value calculation unit 61 holds the recording content evaluation value without adding it. On the other hand, it is estimated that the recorded content that is not selected and operated by the user is highly likely to be unnecessary recorded content for the user. Therefore, in this case, the evaluation value calculation unit 61 adds and holds the evaluation value of the recorded content.

  As a third method, the evaluation value of the recorded content included in the target page may be calculated based on whether or not the recorded content of a page other than the target page is selected by the user. When the target page is switched to another page by the page switching operation of the recording list, and the recorded content of the other page is selected and operated by the user, the recorded content included in the target page may be unnecessary recorded content for the user Estimated to be high. Therefore, in this case, the evaluation value calculation unit 61 adds and holds the evaluation value of the recorded content included in the target page.

  As a fourth method, while displaying the target page of the recording list, the evaluation value of the recorded content is calculated based on whether or not the recorded content of the target page has been held for a predetermined time. The evaluation value calculation unit 61 measures and holds the time when the cursor is placed for each recorded content. It is estimated that the recorded content on which the user has placed the cursor for a predetermined time or longer (for example, 1 second or longer) is highly likely to be necessary recorded content for the user. Therefore, in this case, the evaluation value calculation unit 61 holds the recording content evaluation value without adding it. On the other hand, it is estimated that the recorded content in which the cursor is placed by the user for less than a predetermined time (for example, less than 1 second) is likely to be unnecessary recorded content for the user. Therefore, in this case, the evaluation value calculation unit 61 adds and holds the evaluation value of the recorded content.

  As a fifth method, the evaluation value of the recorded content included in the target page may be calculated based on whether or not the cursor has been placed on the recorded content of a page other than the target page for a predetermined time. When the target page is switched to another page by the page switching operation of the recording list and the user places the cursor over the recorded content on the other page for a predetermined time or longer, the recorded content included in the target page is unnecessary for the user It is estimated that there is a high possibility that the recorded content is correct. Therefore, in this case, the evaluation value calculation unit 61 adds and holds the evaluation value of the recorded content included in the target page.

  When the recording / reproducing apparatus 1 calculates the evaluation value, any one of the first to fifth methods described above may be used, or any of a plurality of methods may be used in appropriate combination.

  FIG. 4 is a flowchart for explaining an example of the evaluation value calculation method by the recording / reproducing apparatus 1 according to the present invention. The first method will be described based on the flow of this example. First, when the user operates the remote controller 9 and receives an instruction to display a recording list, the recording / playback apparatus 1 displays a recording list of recording contents recorded in the HDD 8 (for example, the recording list shown in FIG. 2) on the display 10. Display is started (step S1).

  Next, the recording / reproducing apparatus 1 sets a page being displayed in the recording list over a plurality of pages as a target page for evaluation value calculation in accordance with a user operation on the recording list (step S2). Thereafter, it is determined whether or not the user has moved to another page of the recording list by a user operation (step S3). When it is determined that the user has moved to another page of the recording list (in the case of YES), the display in which the target page is displayed It is determined whether or not the time is larger than the set value stored in the system control unit 6 (step S4). If it is determined in step S3 that the recording list has not been moved to another page (in the case of NO), the process returns to step S2 and the process is repeated. Here, the target page is a page currently being displayed. For example, when the first page is displayed, the first page is a target page for evaluation value calculation, and pages other than the first page are different pages. This is the same for each page.

  Next, when the recording / reproducing apparatus 1 determines in step S4 that the display time of the target page is longer than the set value (in the case of YES), the recording content required by the user exists on the target page. Since it is estimated, the evaluation value of the recorded content included in the target page is not added and is held as it is (step S6). Further, when it is determined that the display time of the target page is equal to or less than the set value (in the case of NO), it is estimated that there is no recorded content required by the user on the target page, so the recording included in the target page “1” is added to the content evaluation value and held (step S5). Then, it is determined whether or not the recording list display is ended by the user's remote control operation or the like (step S7). If it is determined that the recording list display is ended (in the case of YES), the evaluation value calculation processing is ended. On the other hand, if it is determined that the display of the recording list is continuing (NO), the process returns to step S2, and the evaluation value calculation process is repeated for the recorded content included in the target page currently being displayed.

  5 to 7 are flowcharts for explaining other examples of the evaluation value calculation method by the recording / reproducing apparatus 1 according to the present invention. 5 and 6 are flowcharts for explaining the second and third methods described above, and FIGS. 5 and 7 are flowcharts for explaining the fourth and fifth methods described above.

  5 and 6, first, when the user operates the remote controller 9 and receives a recording list display instruction, the recording / playback apparatus 1 receives a recording list of recorded contents recorded in the HDD 8 (for example, as shown in FIG. 2). The recording list is started to be displayed on the display 10 (step S11).

  Next, the recording / reproducing apparatus 1 sets a page being displayed in the recording list over a plurality of pages as a target page for evaluation value calculation in accordance with a user operation on the recording list (step S12). Then, it is determined whether or not a selection operation has been performed for each recorded content on the target page (step S13). If it is determined that the recorded content on the target page has been selected (YES), the recorded content on the target page is determined. Information indicating that the selection operation has been performed and the operation content are stored in the memory. At this time, the time when the cursor is placed for each recorded content of the target page is also stored in the memory (step S14). On the other hand, when it is determined in step S13 that the recorded content of the target page is not selected (NO), the process proceeds to step S15.

  Next, the recording / reproducing apparatus 1 determines whether or not the user has moved to another page of the recording list by a user operation (step S15), and determines that the user has moved to another page of the recording list (in the case of YES) It is determined whether or not a selection operation has been performed for each recorded content on the page (step S16). On the other hand, if it is determined in step S15 that the recording list has not been moved to another page (in the case of NO), the process returns to step S12 and the process is repeated.

  Next, when the recording / reproducing apparatus 1 determines in step S16 that the recorded content on another page has been selected (in the case of YES), information indicating that the recorded content on another page has been selected and its information The operation content is stored in the memory. At this time, the time when the cursor is placed for each recorded content of another page is also stored in the memory (step S17). On the other hand, when it is determined in step S16 that the recorded content of another page is not selected (NO), the process proceeds to step S18.

  Next, the recording / reproducing apparatus 1 determines whether or not the display time during which the target page is displayed is longer than the set value stored in the system control unit 6 (step S18). Here, when it is determined that the display time of the target page is longer than the set value (in the case of YES), reproduction is performed in the target page based on the information indicating that the selection operation is stored in the memory and the operation content. It is determined whether or not there is a recorded content for which a selection operation (such as detailed information display) other than is performed (step S20). If it is determined in step S18 that the display time of the target page is equal to or shorter than the set value (in the case of NO), it is estimated that the recorded content required by the user does not exist on the target page. “1” is added to the evaluation value of the recorded content included in the video content (step S19), and the process proceeds to step S31 in FIG.

  Next, when the recording / reproducing apparatus 1 determines in step S20 that there is recorded content in which a selection operation other than reproduction is performed in the target page (in the case of YES), the recorded content is required by the user. Therefore, the recorded content is not added to the evaluation value of the recorded content but is held as it is (step S21), and the process proceeds to step S31 in FIG. On the other hand, when it is determined that there is no recorded content for which a selection operation other than playback has been executed in the target page (in the case of NO), that is, a selection operation other than playback is executed for the recorded content included in another page. If a selection operation other than playback is not performed on any page, it is presumed that the recorded content required by the user does not exist on the target page. “1” is added to the evaluation value of the recorded content to be stored (step S22), and the process proceeds to step S31 in FIG. Note that, in the above step S20, the recorded content for which the selection operation other than playback is not executed in the target page is likely to be unnecessary recorded content for the user, and therefore the evaluation value of the recorded content is “1”. "May be added and held.

  In FIG. 6, the recording / reproducing apparatus 1 determines whether or not the recording list display is ended by a user's remote control operation or the like (step S31), and determines that the recording list display is ended (in the case of YES), Based on the information indicating the selection operation stored in the memory and the operation content, it is determined whether or not there is a recorded content for which the reproduction operation has been executed in the target page (step S32). If it is determined in step S31 that the display of the recording list is continuing (in the case of NO), the process returns to step S12 of FIG. 5 to repeat the evaluation value calculation process for the recorded content included in the currently displayed target page. .

  Next, when the recording / playback apparatus 1 determines in step S32 that there is recorded content that has been played back in the target page (in the case of YES), the recorded content is recorded content that the user needs. Therefore, it is held without being added to the evaluation value of the recorded content (step S33), and the process is terminated. On the other hand, when it is determined that there is no recorded content for which the playback operation has been executed in the target page (in the case of NO), that is, when the playback operation has been executed for the recorded content included in another page, If the playback operation is not executed for the page, it is presumed that there is no recorded content required by the user on the target page. Therefore, the evaluation value of the recorded content included in the target page is “1”. "Is added and held (step S34), and the process is terminated. Note that in step S32, the recorded content for which the reproduction operation has not been executed in the target page is likely to be unnecessary recorded content for the user, so “1” is added to the evaluation value of the recorded content. And may be held.

  Next, another example of the evaluation value calculation flow will be described based on FIG. 5 and FIG. In the case of this example, the process proceeds from step S19, S21, S22 in FIG. 5 to step S41 in FIG. Since each step of FIG. 5 is as described above, a description thereof is omitted here.

  In FIG. 7, the recording / reproducing apparatus 1 determines whether or not the cursor has been placed on the recorded content of the target page for a predetermined time (for example, 1 second) based on the time at which the cursor is stored for each recorded content stored in the memory. If it is determined that there is a recorded content on which the cursor is placed for a predetermined time or longer in the target page (in the case of YES), the recorded content is likely to be required by the user. Since it is estimated, it is held as it is without being added to the evaluation value of the recorded content (step S43). On the other hand, in step S41, when it is determined that there is no recorded content on which the cursor has been placed for a predetermined time or more in the target page (in the case of NO), that is, the cursor is over a predetermined time for the recorded content included in another page. Is applied, it is presumed that the recorded content required by the user does not exist on the target page, so that “1” is added to the evaluation value of the recorded content included in the target page and held ( Step S42). Note that in step S41, the recorded content in which the cursor is placed on the target page for less than a predetermined time (1 second) is likely to be unnecessary recorded content for the user. “1” may be added to the evaluation value and held.

  Note that the default page when the recording list is first displayed is displayed with the cursor placed on the first recorded content of the normal page. In the example of FIG. 2A described above, the first “title 1” is displayed with the cursor placed on it. In this case, it is considered that the time that the cursor is on “title 1” is longer than that of other titles. Therefore, if the predetermined time (1 second) is set uniformly, the time that the cursor is on is predetermined. There is a problem that it is easy to determine that the time is longer than the time, and “Title 1” is not easily deleted. For this reason, the setting value may be lengthened (for example, 2 seconds) only for the top title of the default page.

  The same problem as described above can also occur in the page switching operation by the user. That is, the cursor is moved by the page switching operation. For example, in page forward, the page is displayed with the cursor on the top title of the next page according to page switching. Displayed with the cursor on the last title of the previous page. For this reason, the set value may be lengthened only for the first and last titles of each page.

  In FIG. 7, finally, the recording / reproducing apparatus 1 executes the processes of steps S44 to S47. The processes of these steps are the same as the processes of steps S31 to S34 of FIG. Omitted.

  In the above description, the evaluation value calculation process has been described by taking the recording list that can reproduce the content recorded in the HDD 8 as an example. However, the evaluation value calculation process is performed on the erasure list that can delete the content recorded in the HDD 8. May be. Some recording / playback apparatuses can display an erase list for the purpose of erasing recorded content. This erasure list is, for example, a list in which contents recorded in the HDD 8 are arranged in order of new or oldest recording date, title name, data volume, etc.

  FIG. 8 is a diagram showing a display example when a content list recorded in the HDD 8 by the content recording processing unit 7 is displayed on the display 10 as a title selection / erasure list. For example, the deletion list is displayed by pressing the “enter” key of the remote controller 9 while the cursor is placed on the “erase” menu on the menu screen displayed after the user presses the “menu” key provided on the remote controller 9. By doing so, it can be displayed on the screen.

  8A and 8B, 40 is a title selection / erasure list, and the title selection / erasure list 40 includes a previous page feed key 41, a recorded content list 42, and a next page feed key 43. The recorded content list 42 in this example is a list of recorded content based on thumbnail images (FIG. 8A) or text information (title, recording date and time, recording time, etc. FIG. 8B). When the recorded content cannot be displayed on one page, it is displayed over a plurality of pages, and the user operates the cursor key or the like of the remote controller 9 to move between pages of the title selection / erasure list to select the desired recorded content. You can see the erase list.

  An evaluation value is calculated for each content recorded in the HDD 8 based on operation information operated by the user with respect to this deletion list. For example, when the deletion list is applied to the processing flow of FIG. 4, contrary to the recording list, the longer the display time, the more the content that is considered unnecessary for the user, and thus the lower the evaluation value. The recorded content has a higher priority of deletion (to be deleted).

  In the processing flows illustrated in FIGS. 4 to 7 described above, a simple process of adding “1” to the evaluation value is described as an example of a simple calculation method. However, the calculation is limited to this calculation method. Instead of this, a more complicated calculation method using multiplication, polynomials, etc., or digit digit alignment by normalization of evaluation values may be performed.

  FIG. 9 is a diagram showing a display example when the erasure candidate list created by the recording / reproducing apparatus 1 according to the present invention is displayed on the display 10. In the drawing, reference numeral 50 denotes an erasure candidate list. The erasure candidate list 50 includes a next page feed key 51, an erase candidate title list 52, and a previous page feed key 53. The erasure candidate title list 52 includes a title number, a title name, a recording date and time, a recording time (minutes), and the like, and based on the above-described evaluation value calculation results, titles with higher erasure priority are arranged in the upper row. . The deletion candidate list 50 is displayed and output on the display 10 by the list display processing unit 63.

  The deletion candidate list 50 can be displayed at a desired timing in accordance with a user operation, but may be automatically displayed when the HDD 8 has a small free recording capacity. In this case, the system control unit 6 functions as a determination unit that determines whether or not the free recording capacity of the HDD 8 is equal to or less than a predetermined value, and the system control unit 6 determines that the free recording capacity is equal to or less than the predetermined value. In this case, the list display processing unit 63 displays and outputs the deletion candidate list 50. Since the user can quickly delete unnecessary titles from the erasure candidate list 50, the free recording capacity of the HDD 8 can be secured to cope with sudden recording.

  In the example of FIG. 9A, in order from the top, No8 (title 62), No30 (title 50), No15 (title 82), No52 (title 73), No46 (title 33), No90 (title 18), No83. Nine titles (Title 11), No. 74 (Title 2), and No. 79 (Title 7) are listed as deletion candidates. Assume that the evaluation values of the titles on the deletion candidate list are, for example, 72, 65, 63, 62, 50, 34, 34, 33, and 32 in order from the top.

  Here, when a transition from the recording list shown in FIG. 3 (A) to the display of the recording list shown in FIG. 3 (B) is performed by the user operation, it is shown in FIG. 4 to FIG. The evaluation value calculation process adds “3” to the evaluation values of No. 74 (title 2) and No. 79 (title 7) among the titles of the recording list shown in FIG. 3A, while No. 90 (title 18). ) And No. 83 (title 11) are assumed to have no change. In this case, the evaluation values of No90 (title 18) are unchanged at 34, No83 (title 11) is unchanged at 34, No74 (title 2) is changed from 33 to 36, and No79 (title 7) is changed. It changes from 32 to 35.

As a result, the evaluation values of No. 74 (title 2) and No. 79 (title 7) become larger than the evaluation values of No. 90 (title 18) and No. 83 (title 11). In this case, the erasure candidate extraction / sort unit 62 rearranges the erasure candidate list based on the evaluation value updated as described above, and the list display processing unit 63 performs the processing as shown in FIG. A list of possible deletion candidates. That is, in the example of FIG. 9B, in order from the top, No8 (title 62), No30 (title 50), No15 (title 82), No52 (title 73), No46 (title 33), No74 (title 2). , No. 79 (title 7), No. 90 (title 18), No. 83 (title 11) are listed as deletion candidates. In this example, the recorded contents whose arrangement order has been changed are highlighted.
Further, the erasure candidate list illustrated in FIG. 9 may be used for the evaluation value calculation process similarly to the title selection erasure list illustrated in FIG. 8, and is based on operation information operated by the user with respect to this erasure candidate list. Thus, the evaluation value may be updated for each content recorded in the HDD 8.

  In the embodiments described so far, the deletion candidate list is rearranged by calculating an evaluation value for each recording content based on operation information operated by the user on the recording list. The sorting condition is not limited, and may include other information such as title information such as title name, recording date / time, recording length, flag indicating whether or not played back, title information such as affiliation genre, in addition to the evaluation value.

  Further, the timing for updating the evaluation value may be performed as needed at the time of transition between pages in the recording list display, or may be collectively performed at the timing when the power of the recording / reproducing apparatus 1 is turned off. In addition, a timing at which a specific key operation (for example, a playback operation of a recorded title, a deletion-dedicated update key operation, etc.) is performed by the user, or a control signal for updating is provided via the external interface of the recording / playback apparatus 1. It may be performed at the input timing.

  In addition, the deletion candidate list displayed to the user not only displays the result of rearranging the display order, but also highlights the changed part of the display order (see the example in FIG. 9B), or arranges it. The deletion candidate list before and after the replacement process may be displayed simultaneously.

  In the above description, the embodiment of the recording / reproducing apparatus has been mainly described. However, the present invention is not limited to the recording / reproducing apparatus, and the control for creating and presenting the erasure candidate list by the recording / reproducing apparatus. A form as a method, a form as a control program for causing a computer to execute the control method, or a form of a computer-readable recording medium on which the control program is recorded may be used.
