[0021]
FIG. 2 shows a hardware configuration of the present embodiment in which the reception system configured as described above is executed. FIG. 2 is basically the same as the configuration of a general-purpose computer system. Further, since the same components as the components of the system shown in FIG. 1 are included, the same components are denoted by the same reference numerals and description thereof is omitted. In FIG. 2, 102 is a main storage device composed of a volatile memory for storing programs, 103 is an auxiliary storage device composed of a nonvolatile memory for storing programs and data, and 101 is a program stored in the main storage device 102. CPU. The program stored in the auxiliary storage device 103 is executed by the CPU 101 after being loaded into the main storage device 102.
[0022]
The operation of the first embodiment configured as described above will be described. In order to explain the operation of the first embodiment in an easy-to-understand manner, here, a description will be given taking reception of a sumo video delivered from a server on the network as an example. As shown in FIG. 3, the server stores additional information such as the name of the wrestler for each approach and the importance level of the approach on that day. In FIG. 3, for example, “Effort (1). Importance” represents the importance in the efforts on the day. Also, `` Effort (1). Component (1). Importance (1) '' represents the importance of Effort (1) .Component (1) .Keyword (1). (1). Component (1). Start time: 02:42:20 ”and Wakanohana's importance in scenes that correspond to“ Approach (1). Component (1). End time: 02:43:34 ” Represents. Such additional information is given in advance by the content provider.
[0023]
In FIG. 3, “additional information interpretation data” and “user profile creation data” are assigned to the slot 4, and these are used to create / update a user profile which is a user's content usage form. “Additional information interpretation data” describes what attributes and attribute values exist in the additional information and their relationships. “User profile creation data” describes rules for creating / updating a user profile as shown in FIG. 4 with reference to “additional information interpretation data”. As a rule for creating a user profile as shown in FIG. 4, the viewing time is accumulated for each genre, sub-genre, and keyword assigned to the video being viewed, and the “importance for the user” is set. It is to calculate.
[0024]
In FIG. 4, for example, user A is watching Sumo or baseball for a longer time than soccer (interesting), and is also often watching Wakanohana's efforts in the sumo program. In this example, “importance for the user” is “the time when the user actually saw a scene to which a certain keyword is assigned” is “the time required to see all the scenes to which the keyword is assigned”. Furthermore, it is normalized within the range of [0, 1] between related keywords (for example, keywords related to sumo wrestling). Here, “additional information interpretation data” and “user profile creation data” have been described as an example of being sent together with a distributed program, but may be stored in advance in the receiving terminal.
[0025]
Hereinafter, the operation of the receiver will be described with reference to the flowchart of FIG.
[STEP1a] Data reception
The receiving unit 1 is waiting for the distribution of content from the broadcast or the network. If the content is distributed, the content and additional information are received and transferred to STEP 2a. Otherwise go to STEP4a.
[STEP2a] Separation of received data
The received data separation unit 2 separates the received data into content and additional information, the additional information is stored in the content additional information storage unit 3, and the content is temporarily stored in the auxiliary storage device 103. If the received data includes “additional information interpretation data” or “user profile creation data” shown in FIG. 3, the content additional information storage means 3 also stores them.
[STEP3a] Content selection
The content selection means 5 refers to the user profile stored in the user profile storage means 4, selects an attribute and attribute value whose “importance for the user” is equal to or greater than a predetermined threshold, and stores it in the content additional information storage means. With reference to the stored additional information, a scene having an attribute value related to the attribute value of the selected user profile is selected in order of importance and time. For example, in the user A shown in FIG. 4, Wakanohana has a high importance level. “Approach (1). Component (1). Keyword (1): Wakanohana, Initiative (1). Component (1). Importance ( 1): 0.5, Effort (1). Component (1). Start time: 02:42:20, Effort (1). Component (1). End time: 02:43:34 "and" Effort (1 ). Component (3). Keyword (1): Wakanohana, Effort (1). Component (3). Importance (1): 0.9, Effort (1). Component (3). Start time: 02: 46:11, Initiative (1). Component (3). End time: 02:48:21 ”are selected and stored in the content storage means 6. At this time, additional information relating to the selected scene is also stored in pairs. In addition, content. Genre and content. Additional information on higher-level concepts such as sub-genre, approach (1), approach name and approach (1), importance is also accumulated at the same time.
[STEP4a] Content usage by users
The content usage support unit 7 always displays the currently accessible content including the content selected by the content selection unit 5 together with the title, and accepts the content usage by the user. If the content is used, play the content and go to STEP5a. Otherwise go to STEP6a.
[STEP5a] Update user profile
The user profile creation / update means 8 stores the user profile stored in the user profile storage means 4 and the “additional information interpretation data” and “user profile creation data” stored in the content additional information storage means 3. If there is a new attribute or attribute value in the additional information that is referred to, it is added to the user profile to calculate “importance for the user”, and the attribute related to the attribute of the information added to the scene being viewed Is in the user profile, the “importance for the user” of the attribute value is updated. For example, if the scene of Takanonami is viewed, the importance of the attribute value “Kinonami” in the user profile is increased.
[STEP6a] Viewing end judgment
If the user does not finish viewing, go to STEP1. When finished, save the current user profile and the selected content and go to END.
[0026]
As described above, in the first embodiment, only the scenes desired for individual users are collected by referring to the additional information of the content components added to the content on the transmission side and the user profile indicating the user's viewing mode. Content can be provided.
[0027]
  NaBookThe importance for the user of the embodiment is an example of the importance of the present invention. The receiving unit of this embodiment is an example of the receiving means of the present invention.BookThe selected content storage means of the embodiment is an example of the recording means of the present invention.
[0028]
Furthermore, the broadcasting station or network in this embodiment is a broadcasting station for CS broadcasting, a broadcasting station for BS broadcasting, a broadcasting station for cable television broadcasting, a computer network, the Internet, etc. It only needs to be able to send content and additional information to the side using the content.
[0029]
Furthermore, in the present embodiment, the case where a sumo video is edited has been described as an example, but the present invention is not limited to this. In short, it can be applied to any content, such as editing a baseball game or editing a drama.
[0030]
Furthermore, in the present embodiment, the constituent elements of the content are described as scenes, but the present invention is not limited to this. Cuts, frames, MPEG GOPs, and objects included in them may be used. For example, when the constituent element is a cut (when the constituent element is divided by camera switching), the additional information described in the present embodiment may be added for each cut. When the component is a frame, additional information may be added for each frame. If the component is an MPEG GOP, additional information may be added for each GOP.
[0031]
(Second Embodiment)
Next, a second embodiment according to the data receiving method of the present invention will be described. In the first embodiment, an example is described in which only the scene that the individual user wants to see is selected by referring to the additional information given to the component of the content on the transmission side and the user profile representing the user's viewing mode. However, in the second embodiment, the storage capacity of the system is checked before accumulating the selected content, and the constituent elements of the content are selected based on the user profile so that the storage capacity can be stored. Is taken into consideration.
[0032]
FIG. 6 is a block diagram of the receiving system according to the second embodiment. The same components as those of the receiving system according to the first embodiment shown in FIG. To do. The difference between the receiving system of the second embodiment and the first embodiment is that the storage capacity remaining amount for changing the content component to be selected in accordance with the remaining amount of the selected content storage unit 6 is selected. It is replaced with the adaptive content selection means 9.
[0033]
The operation of the second embodiment configured as described above will be described with reference to the flowchart of FIG. However, only [STEP3b], which is different from [STEP3a] in the flowchart of FIG. 5 representing the operation of the receiving system of the first embodiment, will be described.
[STEP3b] Select content according to remaining storage capacity
First, the remaining capacity of the storage capacity adaptive type content selection means 9 checks the remaining capacity of the auxiliary storage device 103 allocated for content storage. Next, from the user profile of the user stored in the user profile storage unit 4, an attribute and an attribute value having “importance for the user” equal to or greater than a predetermined threshold are selected and stored in the content additional information storage unit 3. The component having the attribute value related to the attribute value of the selected user profile is selected one by one in descending order of importance so long as the storage capacity is not exceeded, and these are accumulated in time order. For example, in the case of the additional information in FIG. 3 and the user profile in FIG. 4, if the storage capacity of the selected content storage means 6 is 3 minutes 24 seconds or more, all scenes in which Wakanohana appears can be stored. If there is only 30 minutes, the importance is higher "Effort (1). Component (3). Keyword (1): Wakanohana, Effort (1). Component (3). Importance (1): 0.9, Effort (1). Component (3). Start time: 02:46:11, Effort (1). Component (3). End time: 02:48:21 ”only.
[0034]
As described above, in the second embodiment, content components are selected according to the remaining storage capacity, so that only the content portion of the content that is highly important to the user can be selectively stored even when the storage capacity is small. .
[0036]
(Third embodiment)
Next, a third embodiment according to the data receiving method of the present invention will be described. In the second embodiment, the example of changing the constituent elements of the content to be selected based on the user profile so as to be stored in the remaining capacity of the storage capacity has been described. However, the third embodiment is more important for the user. When new content with a high degree of storage is the target of storage and the remaining capacity of the storage capacity is low, the less important part is selected from the components of the already stored content with a lower "importance for the user" It is considered so that contents with higher importance can be accumulated by deleting.
[0037]
FIG. 8 is a block diagram of a receiving system according to the third embodiment. The same components as those of the receiving system according to the second embodiment shown in FIG. To do. The difference between the receiving system of the third embodiment and the second embodiment is that the storage capacity remaining adaptive content selection means 9 is selected and edited again with the components of the existing content of lower importance. The importance comparison type content selection means 10 that increases the capacity for storing new content is replaced.
[0038]
  The third embodiment configured as described aboveFormWill be described with reference to the flowchart of FIG. However, [STEP1a] to [STEP2a] and [STEP4a] to [STEP6a] in the flowchart of FIG. 5 representing the operation of the receiving system of the first embodiment are [STEP1c] to [STEP2c] and [STEP2c] and [STEP2c] in FIG. Since the operations are the same as those of STEP4c] to [STEP6c], description thereof will be omitted, and only [STEP3c # 1] to [STEP3c # 7] representing different operations will be described. These steps are executed by the importance comparison type content selection means 10.
[STEP3c # 1] Select existing content with the lowest importance
When at least one existing content exists, the existing content having the lowest importance for the user is selected. Here, the importance of each content for the user is obtained as follows, for example. The keywords that are additional information of the content and its importance (feature (1) .component (1) .keyword (1) and effort (1) .component (1) in FIG. Focusing on the keyword vector consisting of importance (1), etc., the “importance for the user” of each content is, for example, the keyword in the user profile as shown in FIG. 4 and the keyword vector consisting of importance Is given by the dot product. The larger the inner product value, the higher the “importance for the user”, and the smaller the value, the lower the “importance for the user”. Here, when there are a plurality of identical keywords in the additional information of the content, for example, the importance of the keywords may be added.
[STEP3c # 2] Importance comparison with content to be stored
If the importance of the content to be stored for the user is greater than the importance of the existing content selected in STEP3c # 1, go to STEP3c # 3, otherwise go to STEP3c # 6.
[STEP3c # 3] Increasing storage space by re-editing existing content
The additional information of the existing content selected in STEP 3c # 1 and the keyword and importance of the user profile are referred to, and the portion having low importance for the user is deleted to increase the storage capacity. For example, as the existing contents for user A in FIG. 4, Wakanohana has a high importance in the contents shown in FIG. 3 "Approach (1). Component (1). Keyword (1): Wakanohana, Approach (1)" .Component (1). Importance (1): 0.5, Effort (1). Component (1). Start time: 02:42:20, Effort (1). Component (1). End time: 02 : 43: 34 "and" Effort (1). Component (3). Keyword (1): Wakanohana, Effort (1). Component (3). Importance (1): 0.9, Effort (1). Composition Element 2 (3). Start time: 02:46:11, Effort (1). Component (3). End time: 02:48:21 ”is less important. Delete the latter scene.
[STEP3c # 4]
As a result of the re-editing of the selected existing content, it is checked whether or not the storage capacity is sufficient for the accumulation target content. If it can be stored, go to STEP3c # 5. If capacity is still insufficient, go to STEP3c # 7.
[STEP3c # 5]
Similar to STEP 3a in the flowchart of FIG. 5 representing the operation of the first embodiment, a portion having high importance for the user is accumulated from the current accumulation target content.
[STEP3c # 6]
Only the content that can be stored with the current storage capacity is stored in the current storage target content. [STEP3c # 7] Existing content that has been re-edited is excluded from importance comparison targets, and moved to STEP3c # 1.
Here, although an example in which a low-importance portion is deleted for each existing content has been described, the low-importance content itself may be deleted in order.
[0039]
As described above, in the third embodiment, by comparing the “importance for the user” between the contents, the constituent elements of the less important contents are deleted in the order of the lower importance. Content can be stored with priority.
[0041]
(Fourth embodiment)
Next, a fourth embodiment according to the data management method of the present invention will be described. In the first embodiment, an example in which only scenes desired for individual users are accumulated by referring to additional information of components added to content on the transmission side and a user profile representing a user's viewing mode will be described. However, in the fourth embodiment, the stored content is considered to be managed according to the elapsed time since storage. FIG. 10 is a block diagram of a receiving system according to the fourth embodiment. The same components as those of the receiving system according to the first embodiment shown in FIG. To do. The difference between the receiving system of the fourth embodiment and the first embodiment is that the date and time is further stored at the time of content accumulation, and the importance of the less important content is based on the elapsed time from the accumulation. This is the addition of the elapsed date / time linked content management means 11 that deletes components in descending order.
[0042]
The operation of the fourth embodiment configured as described above will be described with reference to the flowchart of FIG. However, [STEP1d] to [STEP2d] and [STEP4d] to [STEP6d] are [STEP1a] to [STEP2a] to [STEP4a] to [STEP4a] to [STEP6d] in the flowchart of FIG. Since the operation is the same as STEP 6a], the description is omitted, and only [STEP3d] and [STEP7d] representing different operations will be described.
[STEP3d] Content selection and storage of storage date and time
When the content selection means 5 selects and stores an important part of the content for the user, the elapsed date and time linked content management means 11 stores the storage date and time.
[STEP7d] Accumulated content management based on elapsed time
The content management means 11 that is linked to the elapsed date and time makes it more important for the content that has been accumulated for a predetermined period and has not been reproduced until now, in an amount proportional to the elapsed date and time since the accumulation. Remove components in order starting from the least frequent.
[0043]
Here, the constituent elements are sequentially erased by an amount proportional to the elapsed time. Specifically, this means the following. That is, as many scenes as the elapsed time are erased. For example, this means that five scenes are deleted per day. After 4 days, 20 scenes are deleted.
[0044]
As described above, in the fourth embodiment, the contents and the interest of the accumulated contents gradually fade with time. Therefore, by deleting the less important contents sequentially, the information essence for the user can be improved. Can only be managed efficiently.
[0046]
Furthermore, in the present embodiment, the constituent elements of the content that have been accumulated and have not been reproduced until now are deleted, but the present invention is not limited to this. Including the content that has been accumulated and played back to the present, the components that are less important may be deleted sequentially in an amount proportional to the date and time since the accumulation.
[0047]
In the present embodiment, the number of scenes is erased in proportion to the elapsed time, but the present invention is not limited to this. You may delete the scene for the time proportional to elapsed time. For example, deleting a scene for 20 minutes a day.
[0048]
(Fifth embodiment)
Next, a fifth embodiment according to the data management method of the present invention will be described. In the fourth embodiment, the example has been described in which the contents are sequentially deleted from the less important components of the content in an amount proportional to the elapsed time since the accumulation. However, in the fifth embodiment, the user The stored content is managed in accordance with the profile change.
[0049]
FIG. 12 is a block diagram of a receiving system according to the fifth embodiment. The same components as those of the receiving system according to the fourth embodiment shown in FIG. To do. The difference between the receiving system of the fifth embodiment and the fourth embodiment is that the change of the user's usage mode is further checked at a predetermined time interval, and the stored content is determined based on the result of the usage mode change. This is the addition of profile-linked content management means 12 for re-editing.
[0050]
The operation of the fifth embodiment configured as described above will be described with reference to the flowchart of FIG. However, [STEP1e] to [STEP2e] and [STEP4e] to [STEP6e] are [STEP1d] to [STEP2d] to [STEP4d] to [STEP4d] to [STEP6e] in the flowchart of FIG. Since the operation is the same as STEP 6d], the description thereof is omitted, and only [STEP 3e] and [STEP 7e] representing different operations will be described.
[STEP3e] Content selection
The content selection means 5 selects and stores an important part of the content for the user, as in STEP 3a of the first embodiment.
[STEP7e] Stored content management linked to user profile changes
The profile-linked content management unit 12 backs up the user profile every predetermined period. At the same time, the previous backup profile is compared with the profile that has been updated since the previous backup. If the degree of importance for the user changes by more than a predetermined value, it is assumed that the user profile has changed significantly and the existing accumulation Re-edit the content. At this time, the original content may be requested from the server side. If the request cannot be made to the server side, the existing stored content is edited. For example, if the “importance for the user” of the keyword “Wakanohana” is significantly reduced, the scene is deleted from the existing accumulated content. Also, if the user has stopped looking at the sumo itself and the importance of the sub-genre “large sumo” has dropped significantly, the existing accumulated content itself is deleted.
[0051]
As described above, in the fifth embodiment, it is possible to re-edit the content that has been once accumulated according to the user's preference that changes every moment.
[0053]
Furthermore, in the present embodiment, the stored content is re-edited according to the current user profile, but the present invention is not limited to this. If the content receiving side cannot request to transmit the content to the server, it may be re-edited by selecting the accumulated content. There are BS broadcasts and CS broadcasts as cases where it is not possible to request content to be transmitted from the receiving side to the server. In BS broadcasting and CS broadcasting, a program determined at a predetermined time according to a program guide is broadcast. Even in such a case, the present embodiment can be applied. However, each time re-editing, fewer components are accumulated.
[0054]
(Sixth embodiment)
Next, a sixth embodiment according to the data management method of the present invention will be described. In the fourth embodiment, the example in which the contents are sequentially deleted from the less important components in the amount in proportion to the elapsed date and time after the accumulation has been described. However, in the sixth embodiment, the accumulation is performed. When there is an expired part in the content, such a part is considered to be deleted.
[0055]
FIG. 14 is a block diagram of a receiving system according to the sixth embodiment. The same components as those of the receiving system according to the fourth embodiment shown in FIG. To do. The difference between the reception system of the sixth embodiment and the fourth embodiment is that the elapsed date / time linked content management means 11 of the fourth embodiment uses the expired portion of the accumulated content as the content. It is replaced with the expiration date corresponding content management means 13 to be deleted from
[0056]
The operation of the sixth embodiment configured as described above will be described with reference to the flowchart of FIG. However, [STEP1f] to [STEP2f], [STEP4f] to [STEP6f] are [STEP1d] to [STEP2d] to [STEP4d] to [STEP4d] to [STEP6f] in the flowchart of FIG. Since the operation is the same as STEP 6d], the description is omitted, and only [STEP3f] and [STEP7f] representing different operations will be described.
[STEP3f] Select content
The content selection means 5 selects and stores an important part of the content for the user, as in STEP 3a of the first embodiment.
[STEP7f] Accumulated content management corresponding to expiration date
The expiration date-corresponding content management means 13 checks the attribute value of the validity period at a predetermined time or time interval for the stored contents including components having the attribute and attribute value of the validity period. Then, using the expiration date as a trigger, the component is deleted from the stored content. For example, as a component with an expiration date, there is a CM that is stored together with a program, and there is a component that notifies a bargain, a service period, and the like. In such a CM that informs a bargain or service period, the CM becomes unnecessary if the bargain or service period has passed. As described above, the expiration date attribute and the attribute value are added in advance to the constituent elements that become unnecessary after the expiration date. Then, since the component whose expiration date has passed is no longer necessary, it is deleted as described above.
[0057]
In this example, the expiration date is checked every predetermined period. However, when the user actually uses the content including the expiration date, it may be checked and skipped. The expiration date information may be collectively managed by the expiration date-corresponding content management means 13 and the expiration portion may be deleted when the system is started immediately after the expiration date.
[0058]
As described above, in the sixth embodiment, since the expired portion can be deleted from the once accumulated content, the storage area can be used effectively.
[0060]
(Seventh embodiment)
Next, a seventh embodiment according to the data display method of the present invention will be described.
