【0021】
Figure 2 shows the hardware configuration of this embodiment in which the receiving system configured as described above is executed. Figure 2 is basically the same as the configuration of a general-purpose computer system. Further, since the same components as those of the system components shown in FIG. 1 are included, the same components are assigned the same numbers and the description thereof will be 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 non-volatile memory for storing programs and data, and 101 is executing a program stored in the main storage device 102. CPU to do. The program stored in the auxiliary storage device 103 is loaded into the main storage device 102 and then executed by the CPU 101.
【0022】
The operation of the first embodiment configured as described above will be described. In order to explain the operation of the first embodiment more clearly, here, the reception of the sumo wrestling video distributed from the server on the network will be described as an example. As shown in Fig. 3, the server also stores additional information such as the name of the wrestler for each initiative and the importance of the initiative on the day. In FIG. 3, for example, "Effort (1). Importance" represents the importance in the efforts of the day. In addition, "Effort (1). Component (1). Importance (1)" indicates the importance of Initiative (1). Component (1). Keyword (1). In this case, "Effort". The importance of Wakanohana in the scenes corresponding to "(1). Component (1). Start time: 02:42:20" and "Effort (1). Component (1). End time: 02:43:34" Represents. These additional information are given in advance by the content provider.
【0023】
In FIG. 3, "additional information interpretation data" and "user profile creation data" are assigned to slot 4, and these are used for creating / updating a user profile, which is a user's content usage form. "Data for interpreting additional information" describes what kind of attributes and attribute values the additional information has and their relationships. In "Data for creating a user profile", a rule for creating / updating a user profile as shown in FIG. 4 is described with reference to "Data for interpreting additional information". 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 given to the video being viewed, and the "importance for the user" is calculated. It is to calculate.
【0024】
In FIG. 4, for example, user A watches (interests in) sumo wrestling and baseball for a longer time than soccer, and also often sees Wakanohana's efforts in the sumo wrestling program. In this example, "importance to the user" is "the time the user actually saw the scene with a certain keyword" and "the time required to see all the scenes with that keyword". It is divided and normalized to the range of [0,1] between related keywords (for example, keywords related to sumo wrestling). Although the "additional information interpretation data" and the "user profile creation data" have been described here in the example of being sent together with the distributed program, they may be stored in the receiving terminal in advance.
【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 the content from the broadcast or the network, and when the content is distributed, the receiving unit 1 receives the content and additional information and sends it to STEP2a. Other than that, go to STEP4a.
[STEP2a] Separation of received data The received data separation unit 2 separates the received data into content and additional information, stores the additional information in the content additional information storage means 3, and temporarily stores the content in the auxiliary storage device 103. If the received data includes the "additional information interpretation data" and the "user profile creation data" shown in FIG. 3, the content additional information storage means 3 also stores the data.
[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 an attribute value whose "importance to the user" is equal to or higher than a predetermined threshold, and serves as the content addition information storage means. Refer to the stored additional information and select scenes with attribute values related to the attribute values of the selected user profile in order of importance and time. For example, in user A shown in FIG. 4, Wakanohana has a high importance of "Effort (1). Component (1). Keyword (1): Wakanohana, Effort (1). Component (1). Importance (1). 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, Initiative (1). Component (3). Importance (1): 0.9, Initiative (1). Component (3). Start time: 02: Select the two parts of "46:11, Initiative (1). Component (3). End time: 02:48:21" and store them in the content storage means 6. At this time, additional information about these selected scenes is also accumulated in pairs. In addition, additional information on higher-level concepts such as content, genre, content, sub-genre, initiative (1), initiative name, initiative (1), and importance is also accumulated at the same time.
[STEP4a] Content usage by users The content use support means 7 always displays currently accessible contents including the contents selected by the content selection means 5 together with a title and the like, and accepts the use of the contents by the user. If the content is used, play the content and go to STEP5a. Other than that, go to STEP6a.
[STEP5a] User profile update 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 separated additional information, add it to the user profile to calculate the "importance to the user", and the attribute related to the attribute of the information added to the scene being viewed. If is in the user profile, update the "importance to the user" of that attribute value. For example, if you are watching the scene of Takanonami, the importance of the attribute value "Takanonami" in the user profile is increased.
[STEP6a] Judgment of end of viewing If the user does not finish watching, 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 to be seen by each user are collected by referring to the additional information of the content component added to the content on the transmitting side and the user profile representing the viewing mode of the user. Content can be provided.

When the component is a frame, additional information may be added for each frame. Further, when the component is an MPEG GOP, additional information may be added for each GOP.
【0031】
(Second Embodiment) Next, the second embodiment according to the data receiving method of the present invention will be described. In the first embodiment, an example will be described in which only the scenes desired to be viewed by each user are selected by referring to the additional information given to the components of the content on the transmitting side and the user profile representing the viewing mode of the user. However, the second embodiment examines the storage capacity of the system before accumulating the selected content and selects the content components based on the user profile so that it can be stored in the remaining storage capacity. It is considered in.
【0032】
FIG. 6 is a configuration diagram of the receiving system according to the second embodiment, and the same components as those of the receiving system according to the first embodiment shown in FIG. 1 are numbered the same and detailed description is omitted. To do. The difference between the receiving system of the second embodiment and the first embodiment is that the content selection means 5 is selected according to the remaining amount of the selected content storage means 6. The remaining storage capacity is changed according to the remaining amount of the content component. It was replaced by 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 a difference from [STEP3a] in the flowchart of FIG. 5 showing the operation of the receiving system of the first embodiment, will be described.
[STEP3b] Content selection according to the remaining storage capacity By the storage capacity remaining amount adaptive content selection means 9, first, the remaining amount of the capacity allocated to the content storage among the capacities of the auxiliary storage device 103 is checked. Next, an attribute and an attribute value having "importance to the user" equal to or higher than a predetermined threshold value are selected from the user profile of the user stored in the user profile storage means 4, and stored in the content additional information storage means 3. With reference to the additional information provided, the components with attribute values related to the attribute values of the selected user profile are selected one by one in descending order of importance as long as the storage capacity is not exceeded, and they are accumulated in chronological order. For example, in the case of the additional information shown in FIG. 3 and the user profile shown in FIG. 4, if the storage capacity of the selected content storage means 6 is 3 minutes and 24 seconds or more, all the scenes in which Wakanohana appears can be stored. If there is only 30 minutes and 30 seconds, the more important "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 ".
【0034】
As described above, in the second embodiment, since the content components are selected according to the remaining storage capacity, 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. ..
【0035】
The storage capacity remaining amount adaptive content selection means of the present embodiment is an example of the editing means of the present invention.
【0036】
(Third Embodiment) Next, the third embodiment according to the data receiving method of the present invention will be described. In the second embodiment, an example of changing the components of the content selected based on the user profile so that the content can be stored in the remaining storage capacity has been described, but the third embodiment is more important to the user. When new content with a high degree of storage is targeted for storage and the remaining storage capacity is low, the less important part from the components of the already stored content with lower "importance to the user" is selected. By deleting it, it is considered so that more important contents can be accumulated.
【0037】
FIG. 8 is a configuration diagram of the receiving system according to the third embodiment, and the same components as those of the receiving system according to the second embodiment shown in FIG. 6 are numbered the same and detailed description is omitted. 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 by selecting and editing the components of the existing content, which is less important. , It was replaced by the importance comparison type content selection means 10 that increases the capacity for accumulating new contents.
【0038】
The operation of the mobile phone of the third embodiment configured as described above will be described with reference to the flowchart of FIG. However, [STEP1a] to [STEP2a] and [STEP4a] to [STEP6a] in the flowchart of FIG. 5 showing the operation of the receiving system according to the first embodiment are [STEP1c] to [STEP2c] and [STEP2c] in FIG. 9, respectively. Since the operation is the same as STEP4c] to [STEP6c], the explanation is omitted, and only [STEP3c # 1] to [STEP3c # 7], which represent different operations, will be explained. These steps are performed by the importance-comparative content selection means 10.
[STEP3c # 1] Selection of existing content with the lowest importance If at least one existing content exists, select the existing content that is least important to the user. Here, the importance of individual contents to the user is obtained, for example, as follows. As a feature that expresses the content, keywords that are additional information of the content and their importance (in Fig. 3, efforts (1). Components (1). Keywords (1) and efforts (1). Components (1). ). Focusing on the keyword vector consisting of importance (1), etc.), the "importance for the user" of each content is, for example, the keyword vector consisting of the keyword and importance in the user profile as shown in Fig. 4. Given by the inner product of. It is judged that the larger the value of the inner product, the higher the "importance to the user", and the smaller the value, the lower the "importance to the user". Here, when there are a plurality of the same keywords in the additional information of the content, for example, the importance of the keywords may be added.
[STEP3c # 2] Comparison of importance with the content to be stored If the importance of the content to be stored to 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] Increased storage area by re-editing existing content Refer to the additional information of the existing content selected in STEP3c # 1 and the keywords and importance of the user profile, delete the parts that are less important to the user, and increase the storage capacity. For example, as the existing content for user A in Fig. 4, Wakanohana has the highest importance among the contents shown in Fig. 3. "Efforts (1). Components (1). Keyword (1): Wakanohana, Efforts (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" Efforts (1). Components (3). Keyword (1): Wakanohana, Efforts (1). Components (3). Importance (1): 0.9, Efforts (1) If the two parts of "Component (3). Start time: 02:46:11, Effort (1). Component (3). End time: 02:48:21" are accumulated, it is more important. Delete the latter scene with a low.
[STEP3c # 4] As a result of re-editing the selected existing content, it is checked whether the storage capacity of the content to be stored has enough storage capacity. If it is judged that it can be stored, go to STEP3c # 5. If you still run out of space, go to STEP3c # 7.
[STEP3c # 5] Similar to STEP3a of the flowchart of FIG. 5 showing the operation of the first embodiment, the portion of the current storage target content that is highly important to the user is stored.
[STEP3c # 6] The current storage target content is stored only in the part that can be stored with the current storage capacity.
[STEP3c # 7] Exclude the re-edited existing content from the importance comparison target and go to STEP3c # 1. In addition, although the example of deleting the less important part of each existing content has been described here, the less important contents themselves may be deleted in order.
【0039】
As described above, in the third embodiment, by comparing the "importance to the user" between the contents, the components of the less important contents are deleted in ascending order of importance, so that the higher importance is given. Content can be stored with priority.
【0040】
The importance comparison type content selection means of the present embodiment is an example of the editing means of the present invention.
【0041】
(Fourth Embodiment) Next, the fourth embodiment according to the data management method of the present invention will be described. In the first embodiment, an example of accumulating only the scenes that each user wants to see by referring to the additional information of the component added to the content on the transmitting side and the user profile representing the viewing mode of the user will be described. However, in the fourth embodiment, consideration is given to managing the stored contents according to the elapsed time from the storage. FIG. 10 is a configuration diagram of the receiving system according to the fourth embodiment, and the same components as those of the receiving system according to the first embodiment shown in FIG. 1 are numbered the same and detailed description is omitted. To do. The difference between the receiving system of the fourth embodiment and the first embodiment is that the date and time are stored at the time of content accumulation, and the less important content is more important based on the elapsed time from the accumulation. This is the addition of the elapsed date-linked content management means 11 that deletes the components in ascending order from the lowest.
【0042】
The operation of the fourth embodiment configured as described above will be described with reference to the flowchart of FIG.
