Description

  The invention described in the claims of the present application is audiovisual information data such as image information data, audio information data, and the like, which is accompanied by reproduction history information representing the reproduction history of the audiovisual information represented by the data. The present invention relates to an audiovisual information data processing apparatus that performs storage and storage state display.

  In an information reproduction system configured using a personal computer, audiovisual information data such as image information data and audio information data is stored in a memory unit, and a selected one of the stored audiovisual information data is appropriately selected. In general, reading out from the memory unit and reproducing the audio-visual information represented by it as an image, sound, or image and sound is widely performed. In such a case, the audio-visual information data stored in the memory unit is often accompanied by reproduction restriction information representing restrictions on reproduction of the audio-visual information that is represented, that is, audio-visual information data with reproduction restriction information. Absent. The reproduction restriction information accompanying the audiovisual information data with reproduction restriction information is, for example, reproduction period restriction information for restricting reproduction of audiovisual information represented by the audiovisual information data for a period of time by determining a reproduction allowable period for the reproduction. The reproduction of the audio-visual information represented by the audio-visual information data is used as reproduction frequency limit information for limiting the number of reproductions by determining the allowable reproduction frequency.

  The audiovisual information data with reproduction restriction information stored in the memory unit in the information reproduction system is the audiovisual information that is indicated when the reproduction allowable period indicated by the reproduction restriction information has passed or when the reproduction allowable number has been reached. The audiovisual information cannot be reproduced even if the reproduction is performed. That is, when the allowable playback period has passed, or when the allowable playback count has been reached, the audiovisual information data is stored in the memory unit, but the audiovisual information represented by it cannot be played back. It is. If the audiovisual information data with reproduction restriction information placed in such a state is stored in the memory unit for a long time, the storage capacity of the memory unit is merely reduced. There is a risk of becoming something.

  In relation to this, the audio restriction information data with reproduction restriction information stored in the memory unit has been confirmed, and when the restriction represented by the reproduction restriction information is functioning, the audio / visual information data is confirmed. A system has been proposed in which the idea of automatically deleting the memory from the memory unit is taken (see Patent Document 1). In such a conventionally proposed system, the image data recorded by the digital camera is stored in the hard disk constituting the memory unit together with the data indicating the expiration date, and then stored in the hard disk. A search is performed on the image data, and it is determined whether or not the expiration date of the searched image data has passed. If the expiration date has not passed, the saving of the image data stored on the hard disk is continued as it is. If the expiration date has passed, the image data is automatically deleted from the hard disk. As a result, the system user is freed from checking the free space of the hard disk and the like, and the burden of data management work is reduced.

  The audiovisual information data stored in the memory unit in the information reproduction system as described above is accompanied by reproduction history information representing the history of reproduction of the audiovisual information represented by the data, that is, with reproduction history information. Often referred to as audiovisual information data. The reproduction history information accompanying the audiovisual information data with the reproduction history information stored in the memory unit is, for example, the number of times the audiovisual information is reproduced since the audiovisual information data is stored in the memory unit, the audiovisual information data. Indicates the number of reproductions of the audiovisual information represented by an arbitrary set period after the image is stored in the memory unit, the latest reproduction date and time of the audiovisual information represented by the audiovisual information data, and the like.

  When a large number of such audiovisual information data with reproduction history information is sequentially stored in the memory unit, the audiovisual information represented by the audiovisual information data with reproduction history information stored in the memory unit Has not been played even after a predetermined time has passed since the audiovisual information data is stored in the memory unit, or after the audiovisual information data is stored in the memory unit. It is not uncommon to include things that have never been done in a recent period of time. The audiovisual information data with reproduction history information placed in such a state is unlikely to be required to reproduce the audiovisual information represented by it, and it is stored in the memory unit for a long time. In the case of continuing to store, the storage capacity of the memory unit is automatically changed, as in the case of the audiovisual information data with the reproduction restriction information that has passed the reproduction allowable period or the reproduction allowable number has been reached. There is a risk that it is merely reduced.

Therefore, such a state that the audiovisual information has not been reproduced even though a predetermined time has elapsed since being stored in the memory unit, or the latest after being stored in the memory unit For audiovisual information data with reproduction history information that has never been reproduced for a certain period of time, the image data whose expiration date has passed is automatically read from the hard disk. It is conceivable to automatically delete from the memory unit so as to be deleted.
Japanese Patent Application Laid-Open No. 2000-20687

  However, the audiovisual information is not reproduced even though a predetermined time has elapsed since the audiovisual information data with reproduction history information stored in the memory unit in the information reproduction system has been stored in the memory unit. If the audiovisual information has never been played back in a state that has been stored in the memory unit or in a certain period of time after being stored in the memory unit, it is automatically deleted from the memory unit. In this case, the user of the system feels uncomfortable with the change in the storage state of the audiovisual information data in the memory unit. This is because the audiovisual information data with the reproduction history information is stored in the memory unit under the positive intention of the user of the system, and thus the reproduction history information with the reproduction history information stored in the memory unit is added. This is because the audiovisual information data is deleted from the memory part without confirmation of the intention of the user of the system without any knowledge of the user of the system.

  Accordingly, the audiovisual information is never reproduced even though a predetermined time has elapsed since the audiovisual information data with reproduction history information stored in the memory unit in the information reproduction system has been stored in the memory unit. Or when the audiovisual information has never been played back in a certain period of time after being stored in the memory unit, it is not automatically deleted from the memory unit. Therefore, the user of the information reproduction system can easily confirm that the audiovisual information data with reproduction history information stored in the memory unit in the information reproduction system is in such a state, and the user's active It is desired that the audiovisual information data be deleted from the memory unit as necessary based on the intention of the user. In this way, even when a predetermined time has elapsed since the audiovisual information data with reproduction history information stored in the memory unit in the information reproduction system has been stored in the memory unit, the audiovisual information has been reproduced once. When the audiovisual information has not been played back in a state that has not been performed or in a recent fixed period after being stored in the memory unit, the audiovisual information data is deleted from the memory unit. However, by being performed under the positive intention of the user, a situation in which the user feels uncomfortable with the change in the storage state of the audiovisual information data in the memory unit is avoided.

  However, the audiovisual information is not reproduced even though a predetermined time has elapsed since the audiovisual information data with reproduction history information stored in the memory unit in the information reproduction system has been stored in the memory unit. Or when the audiovisual information has never been reproduced in a certain period of time after being stored in the memory unit, the deletion of the audiovisual information data from the memory unit is In order to be performed based on the positive intention of the user of the reproduction system, the user of the information reproduction system uses the audiovisual information data with reproduction history information stored in the memory unit in the information reproduction system. A state in which audiovisual information has never been reproduced even though a predetermined time has elapsed since being stored in the memory unit, or the memory unit In a recent predetermined period after being stored, that it has been placed in a state in which the reproduction of audiovisual information has not been performed even once, to be to be able to quickly and easily recognize is required. The user of the information reproduction system reproduces the audiovisual information regarding the audiovisual information data with reproduction history information stored in the memory unit in the information reproduction system, even though a predetermined time has elapsed since the data was stored in the memory unit. If it is not possible to recognize that the audiovisual information has not been reproduced in a state in which the audiovisual information has not been reproduced in a state where the audiovisual information has not been performed, or in a recent fixed period after being stored in the memory unit, This is because the intention to delete the information data from the memory unit does not work.

  However, in the past, for audiovisual information data with reproduction history information stored in the memory unit in the information reproduction system that has been adapted to such a request, a predetermined time has elapsed since the audio / visual information data was stored in the memory unit. The audiovisual information has never been reproduced despite the passage of time, or the audiovisual information has not been reproduced in a certain period of time after being stored in the memory unit. There is no data processing system in which the user of the information reproduction system can quickly and easily recognize this.

Affection Play a playback function.

  Audiovisual information data stored in the HDD 20 by the data storage function performed by the CPU 21 is placed under a directory structure as shown in FIG. 2, for example, formed by the data management function performed by the CPU 21. In the directory structure shown in FIG. 2, the HDD 20 is provided with a plurality of primary folders FOLDER α, FOLDER β,. Under the primary folder FOLDER α, there are m secondary folders ALBUM 1, ALBUM 2, ..., ALBUM m (m is a positive integer), and the primary folders FOLDER β, including the primary folder FOLDER β. There are as many secondary folders as necessary under each primary folder other than α. Next, n (n is a positive integer) files TRACK 1, TRACK 2,..., TRACK n are provided under the secondary folder ALBUM 1, and the secondary folder ALBUM 2 and other files are included. There are as many files as necessary under each secondary folder other than the next folder ALBUM1. The audiovisual information data stored in the HDD 20 is stored in files such as files TRACK 1, TRACK 2,.

  In this manner, the audiovisual information data stored in the HDD 20 includes reproduction history information representing the reproduction history of the audiovisual information that is represented, that is, audiovisual information data with reproduction history information. The reproduction history information accompanying the audiovisual information data with such reproduction history information is, for example, the number of reproductions of the audiovisual information represented when the audiovisual information data is stored in the HDD 20, and the audiovisual information data is stored in the HDD 20. Thereafter, the number of reproductions of the audiovisual information represented by an arbitrary set period, for example, the recent certain period, the latest reproduction date and time of the audiovisual information represented by the audiovisual information data, and the like are indicated.

  When a plurality of audiovisual information data including audiovisual information data with reproduction history information is stored in the HDD 20, the CPU 21 performs a data information reproduction function according to command data from the input operation unit 18, for example. The following control operation is carried out at.

  First, the data forming unit 31 incorporated in the CPU 21 causes the image data processing unit 24 and the image display unit 25 included in the information reproducing unit 19 to display content list data representing a list of audiovisual information data stored in the HDD 20. The image data of the list is formed as image information data to be displayed, and is stored in the RAM 22, for example. This content list data is formed for each ALBUM that is a secondary folder in the directory structure formed for the HDD 20, for example. That is, each content list data represents, for example, a list of audiovisual information data stored in TRACK, which is a plurality of files belonging to one secondary folder ALBUM.

  On the other hand, the history information detection means 32 built in the CPU 21 has, for example, at least at least audiovisual information data with reproduction history information included in the list list represented by each content list data formed by the data formation means 31. The number of reproductions of the audiovisual information since the audiovisual information data is stored in the HDD 20, and the reproduction history information indicating the number of reproductions of the audiovisual information in a recent fixed period after the audiovisual information data is stored in the HDD 20. Perform detection. The low reproduction frequency data recognizing means 33 built in the CPU 21 refers to the reproduction history information detected by the history information detecting means 32, and the list list represented by each content list data formed by the data forming means 31. Of the audio-visual information data with reproduction history information included in the audio-visual information represented by the audio-visual information data is not yet played even though a predetermined time has elapsed since the audio-visual information data was stored in the HDD 20. Or data that has not been made in a recent fixed period after the audio-visual information data is stored in the HDD 20 is recognized as low reproduction frequency data.

  Subsequently, when the image display control means 34 built in the CPU 21 displays the image of the list list represented by each content list data formed by the data forming means 31, the image display of the list list is displayed. Processing for making the display portion of the audiovisual information data with reproduction history information recognized as low reproduction frequency data by the low reproduction frequency data recognizing means 33 into a portion where specific display is performed so that the existence thereof can be easily recognized. Apply. As a result of the processing for each content list data formed by the data forming means 31 performed by the image display control means 34, the low reproduction frequency data recognition means 33 in the image display of the list list represented by each content list data. For example, the portion where the specific display corresponding to the audiovisual information data with the reproduction history information recognized as the low reproduction frequency data is performed is a portion where the display is emphasized compared to the display portion around the portion, The display part around the part is displayed in reverse, or the part is displayed with a color different from the display part around the part.

  However, when there is no audiovisual information data with reproduction history information recognized as low reproduction frequency data by the low reproduction frequency data recognizing means 33, the image display control means 34 uses each content list formed by the data forming means 31. Do not perform any processing on the data.

  Thus, each content list data formed by the data forming unit 31 or each content list data formed by the data forming unit 31 and processed by the image display control unit 34 is stored in the image display control unit 34. Thus, the image data is supplied from the CPU 21 to the image data processing unit 24 included in the information reproducing means 19 through the data bus line 11. The image data processing unit 24 performs processing such as digital / analog conversion on each content list data to form an image display signal representing a list of audiovisual information data based on the content list data. The image is supplied to the image display unit 25 included in the information reproducing means 19. As a result, the image display unit 25 displays an image of a list of audiovisual information data belonging to one secondary folder, ALBUM, for example. At this time, when each content list data formed by the data forming unit 31 and processed by the image display control unit 34 is supplied to the image data processing unit 24 as image information data, the image display unit 25 For example, the audiovisual information data with reproduction history information in which the image display of the list of audiovisual information data belonging to one secondary folder ALBUM is recognized as low reproduction frequency data by the low reproduction frequency data recognition means 33 For example, as shown in FIG. 3, the display includes a portion where the specific display corresponding to is performed.

  The image display example for the list shown in FIG. 3 is the audiovisual information data belonging to ALBUM: “001 aaaaaaaaa”, which is the secondary folder under the primary folder “001 FOLDER α”: “001 bbb”, “002 ccc” , “003 ddddddd”, “004 eeeeee”, “005 ffff”,..., “N ababab”. In the image display example of the list shown in FIG. 3, the audiovisual information data: “002 ccc” is recognized as low reproduction frequency data by the low reproduction frequency data recognizing means 33 with audio history information data. That is, reproduction of the audiovisual information represented by the audiovisual information is not yet performed after a predetermined time has elapsed since the audiovisual information data is stored in the HDD 20, or the audiovisual information data is stored in the HDD 20. Is the audiovisual information data with reproduction history information that has not been made in a recent fixed period of time, and therefore the image display portion corresponding to the audiovisual information data: “002 ccc” is displayed in a specific manner. In other words, the display is performed, for example, the display is performed with a color different from the periphery of the portion.

  As described above, during the image display of the list list, the reproduction of the audiovisual information is not yet performed after a predetermined time has elapsed since the audiovisual information data is stored in the HDD 20, or The list list is provided by providing a part for specific display corresponding to the audiovisual information data with reproduction history information that has not been made in a recent fixed period after the audiovisual information data is stored in the HDD 20. The user of the apparatus shown in FIG. 1 who is viewing the image display of the audiovisual information data with the reproduction history information stored in the HDD 20 reproduces the audiovisual information represented by the audiovisual information data. What has not been done yet after a predetermined time has passed since it was saved in the HDD 20, or Those audio information data has not been made in a predetermined period after being stored in the HDD 20, it can be quickly and easily recognized. If necessary, the audio / visual information data with the reproduction history information is reproduced with the active intention of the user, and the audio / visual information is reproduced after the audio / visual information data is stored in the HDD 20. However, the state in which the audiovisual information data has not been performed in a recent period after the audiovisual information data is stored in the HDD 20 is deleted from the HDD 20.

  Then, for example, the user of the apparatus shown in FIG. 1 who has seen the image display example for the list shown in FIG. 3 adds an asterisk (*) in FIG. 3 to reproduce the audiovisual information. As shown, when the audiovisual information data: “005 ffff” is selected, the CPU 21 reads out the audiovisual information data: “005 ffff” stored in the HDD 20 from the HDD 20 accordingly, and the data bus line 11 To the information reproducing means 19, and the information reproducing means 19 sets an operation state in which the audiovisual information represented by the audiovisual information data “005 ffff” is reproduced.

  FIG. 4 is a flowchart showing an example of a control program executed when the CPU 21 operates the data forming means 31, the history information detecting means 32, the low reproduction frequency data recognizing means 33 and the image display control means 34 incorporated therein. .

  In the control program represented by the flowchart shown in FIG. 4, after the start, in step 41, it is determined whether audiovisual information data is stored in the HDD 20. As a result, when the audiovisual information data is not stored in the HDD 20, the program is terminated. On the other hand, if the audiovisual information data is stored in the HDD 20, in step 42, content list data representing a list for the audiovisual information data stored in the HDD 20 is formed.

  Subsequently, in step 43, the reproduction history information is detected for each of the audiovisual information data with reproduction history information included in the list list represented by each content list data formed in step 42. Next, in step 44, with reference to the reproduction history information detected in step 43, the audiovisual information data with reproduction history information included in the list list represented by each content list data formed in step 42 is included. Then, it is determined whether or not the audiovisual information represented by it has not been reproduced even though a predetermined time has elapsed since it was stored in the HDD 20.

  As a result, some of the audiovisual information data with reproduction history information included in the list has not been reproduced yet even though a predetermined time has elapsed since it was stored in the HDD 20. If there is, the audiovisual information data with the reproduction history information is recognized as low reproduction frequency data, and the process proceeds to step 45. In step 45, when the image of the list list represented by each content list data formed in step 42 is displayed, the reproduction recognized as the low reproduction frequency data in step 44 in the image display of the list. The display part of the audiovisual information data with history information is subjected to a specific display process for making a specific display part that can easily identify its presence, and the process proceeds to step 46.

  On the other hand, as a result of the determination in step 44, the audiovisual information represented by the audiovisual information data with the reproduction history information included in the list is shown even though a predetermined time has elapsed since the data was stored in the HDD 20. If there is no item that has not yet been reproduced, the process proceeds directly to step 46. In step 46, with reference to the reproduction history information detected in step 43, the HDD 20 includes the audiovisual information data with reproduction history information included in the list list represented by each content list data formed in step 42. It is determined whether or not there is a piece of audio-visual information that has not been reproduced during a certain period of time after being stored.

  As a result, when there is audiovisual information data with reproduction history information included in the list that has not been reproduced for the audiovisual information that it represents in a recent fixed period after being stored in the HDD 20. Recognizes the audiovisual information data with the reproduction history information as low reproduction frequency data, and proceeds to step 47. In step 47, when the list list image displayed by each content list data formed in step 42 is displayed, the reproduction recognized as the low reproduction frequency data in step 46 in the image display of the list list. The display part of the audiovisual information data with history information is subjected to a specific display process for making a specific display part whose presence can be easily identified, and the process proceeds to step 48.
