[0019] In this way, by acquiring rating information created based on user operations on recorded content from multiple broadcast receiving devices and transmitting the aggregated rating values ​​based on the multiple rating information to the broadcast receiving device, the aggregated rating values ​​can be provided to the broadcast receiving device without requiring users to directly evaluate the content. Therefore, the broadcast receiving device can present content that is popular among multiple users to the user without imposing a burden on the user. This can more effectively support the user in selecting recorded content to watch.

[0020] (5) In (4) above, the aggregation result providing unit may receive a content list from the broadcast receiving device and transmit the aggregation result of the evaluation values ​​of the content indicated in the received content list to the broadcast receiving device.

[0021] With this configuration, the broadcast receiving device can be provided with the results of tallying the evaluation values ​​of the content that has been recorded on the broadcast receiving device among the plurality of contents, which allows the broadcast receiving device to present to the user the content that is popular among a plurality of users with simple processing, compared to a configuration in which the results of tallying all the content are provided to the broadcast receiving device.

[0022] (6) A content evaluation method according to an embodiment of the present disclosure is a content evaluation method in a broadcast receiving device, and includes the steps of creating evaluation information indicating an evaluation value of the content based on user operations on the content recorded in the broadcast receiving device, and transmitting the created evaluation information to a server outside the broadcast receiving device.

[0023] In this way, by using a method for generating rating information based on user operations on recorded content, rating information can be generated without requiring direct user ratings of the content, and rating information can be generated and transmitted to a server without imposing a burden on the user. Furthermore, for example, by feeding back the aggregated results of rating values ​​based on multiple rating information generated by multiple broadcast receiving devices from the server to the broadcast receiving device, it is possible to present to the user content that is popular among multiple users. Therefore, it is possible to more effectively support the selection of recorded content to watch.

[0024] (7) An evaluation value aggregation method according to an embodiment of the present disclosure is an evaluation value aggregation method in an evaluation value aggregation device, and includes the steps of acquiring a plurality of pieces of evaluation information, each created by a plurality of broadcast receiving devices, and indicating the evaluation value of the content, created based on user operations on the content to be recorded, creating an aggregation result of the evaluation value of the content based on the acquired plurality of evaluation information, and transmitting the created aggregation result to the broadcast receiving device.

[0025] In this way, by acquiring rating information created based on user operations on recorded content from multiple broadcast receiving devices and transmitting the aggregated rating values ​​based on the multiple rating information to the broadcast receiving device, the aggregated rating values ​​can be provided to the broadcast receiving device without requiring users to directly evaluate the content. Therefore, the broadcast receiving device can present content that is popular among multiple users to the user without imposing a burden on the user. This can more effectively support the user in selecting recorded content to watch.

[0026] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the drawings, identical or corresponding parts are designated by the same reference numerals, and their description will not be repeated. Furthermore, at least some of the embodiments described below may be combined in any manner.

[0027] [Configuration and basic operation] 1 is a diagram illustrating a configuration of a management system according to an embodiment of the present disclosure. Referring to FIG. 1, management system 301 includes a plurality of broadcast receiving devices 101, a plurality of display devices 111, and a server 201. Server 201 is an example of an evaluation value aggregation device. Broadcast receiving device 101 and display device 111 are installed in a user's home.

[0028] The broadcast receiving device 101 is, for example, an STB. The broadcast receiving device 101 is capable of receiving content via digital broadcasting and content via IP broadcasting such as VOD (Video On Demand), and recording and playing back the received content. More specifically, the broadcast receiving device 101 receives a stream in which content is divided into multiple broadcast packets. The broadcast receiving device 101 plays back the received or recorded content on a display device 111 connected to the broadcast receiving device 101.

[0029] The display device 111 is, for example, a television device. The display device 111 is connected to the broadcast receiving device 101 via, for example, an HDMI (registered trademark) cable. The display device 111 displays the content played back by the broadcast receiving device 101 on the screen.

[0030] The server 201 is, for example, a cloud server. The server 201 may also be a standalone server. The server 201 is capable of communicating with a plurality of broadcast receiving devices 101 via a network.

[0031] (Configuration of broadcast receiving device) FIG. 2 is a diagram illustrating an overview of the configuration of a broadcast receiving device according to an embodiment of the present disclosure. Since the multiple broadcast receiving devices 101 in the management system 301 have the same configuration, the configuration of one broadcast receiving device 101 will be described below. Referring to FIG. 2, the broadcast receiving device 101 includes a receiving unit 10, a processing unit 20, and a storage unit 30. One or both of the receiving unit 10 and the processing unit 20 are realized, for example, by a processing circuit including one or more processors. The storage unit 30 is, for example, a non-volatile memory such as a non-volatile random access memory (NVRAM) included in the processing circuit.

[0032] The receiving unit 10 receives the stream via a network such as the Internet or via an antenna. More specifically, the receiving unit 10 receives broadcast packets that make up the stream and outputs the received broadcast packets to the processing unit 20. The stream includes, for example, audio information, video information, EPG (Electronic Program Guide) information, subtitle information, and SI (Service Information). The broadcast packets are, for example, IP packets that include TCP (Transmission Control Protocol) packets.

[0033] The processing unit 20 stores the broadcast packets received from the receiving unit 10 in the storage unit 30. The processing unit 20 also performs processing to output content. More specifically, the processing unit 20 performs processing to play content using information stored in the storage unit 30, and transmits the obtained video information, audio information, etc. to the display device 111. The processing unit 20 also exchanges information with the server 201 via a network.

[0034] 3 is a diagram illustrating a detailed configuration of a broadcast receiving device according to an embodiment of the present disclosure. Referring to FIG. 3, a processing unit 20 in a broadcast receiving device 101 includes an operation receiving unit 21, a content processing unit 22, an evaluation unit 23, a communication unit 24, and a notification unit 25. A storage unit 30 in the broadcast receiving device 101 includes a recording DB 31, a program information DB 32, and a reservation management DB 33. The communication unit 24 is an example of an evaluation information transmission unit and an example of a counting result acquisition unit.

[0035] For example, the broadcast receiving device 101 is connected to an HDD (Hard Disk Drive) 40 via a USB (Universal Serial Bus) cable. The broadcast receiving device 101 may be connected to a plurality of HDDs 40, or may be connected to a USB memory or an SSD (Solid State Drive) instead of the HDD 40.

[0036] The recording DB 31 is a database of recorded content. Hereinafter, recorded content will also be referred to as recorded content. Identification information for each recorded content is registered in the recording DB 31. For example, the identification information includes at least one of a network ID, a transport stream ID, a service ID, and a program start date and time.

[0037] The program information DB 32 is a database of broadcast programs. In the program information DB 32, an event information table (EIT) acquired from the stream by the receiving unit 10 and a program guide based on an EPG created using the EIT, etc. are registered as program information. The receiving unit 10 periodically acquires the EIT, and the program information DB 32 is periodically updated.

[0038] The reservation management DB 33 is a database of reserved programs, and the program title, broadcast start time, broadcast end time, etc. of each program are registered in the reservation management DB 33.

[0039] The operation accepting unit 21 accepts a user operation, which is an operation performed by a user of the broadcast receiving device 101. More specifically, the operation accepting unit 21 receives an operation signal indicating the user operation from a remote control (not shown), and outputs operation information indicating the user operation to the content processing unit 22, the evaluation unit 23, and the notification unit 25.

[0040] The content processing unit 22 records the content. More specifically, the content processing unit 22 receives operation information related to a recording reservation from the operation reception unit 21, and in accordance with the received operation information, refers to the program guide registered in the program information DB 32 and registers information related to the program to be reserved for recording in the reservation management DB 33. The content processing unit 22 refers to the reservation management DB 33 and records the program, i.e., the content, in accordance with the start time of the program.

[0041] Specifically, the content processing unit 22 controls the receiving unit 10 to acquire broadcast packets corresponding to the content to be recorded, store them in the HDD 40 as recorded content, and register identification information of the recorded content in the recording DB 31. The content processing unit 22 may store the recorded content in an HDD built into the broadcast receiving device 101 instead of the external HDD 40. The content processing unit 22 may also receive operation information related to recording of a program currently being broadcast from the operation accepting unit 21 and record the content in accordance with the received operation information. The content processing unit 22 may also selectively and automatically record content in a genre that matches the user's preferences based on information indicating the user's preferences.

[0042] The content processing unit 22 also plays back the recorded content. More specifically, the content processing unit 22 receives operation information related to the playback of the recorded content from the operation reception unit 21, and acquires broadcast packets corresponding to the recorded content indicated by the received operation information from the HDD 40. The content processing unit 22 then performs processing to play back the recorded content using information, etc., contained in the acquired broadcast packets, and transmits the acquired video information, audio information, etc., to the display device 111.

[0043] Furthermore, the content processing unit 22 erases the recorded content. More specifically, the content processing unit 22 receives operation information relating to erasure of the recorded content from the operation reception unit 21, erases the broadcast packets corresponding to the recorded content indicated by the received operation information from the HDD 40, and erases the identification information of the recorded content from the recording DB 31.

[0044] The content processing unit 22 also protects and removes protection from recorded content. More specifically, the content processing unit 22 receives operation information related to the protection of recorded content from the operation reception unit 21 and turns on the protection setting for the recorded content indicated by the received operation information. The content processing unit 22 also receives operation information related to the removal of protection from recorded content from the operation reception unit 21 and turns off the protection setting for the recorded content indicated by the received operation information.

[0045] (Creating evaluation information) The evaluation unit 23 generates evaluation information indicating evaluation points, which are evaluation values ​​of content, based on user operations on content recorded in the broadcast receiving device 101. For example, the evaluation unit 23 starts generating the evaluation information when it receives permission from the user to generate the evaluation information.

[0046] 4 is a diagram illustrating an example of an evaluation table stored in a storage unit in a broadcast receiving device according to an embodiment of the present disclosure. Referring to FIG. 4, the evaluation unit 23 creates an evaluation table T1 indicating a correspondence between content identification information and evaluation points for the content as evaluation information, based on operation information received from the operation reception unit 21. The evaluation unit 23 stores the created evaluation table T1 in the storage unit 30.

[0047] More specifically, when the evaluation unit 23 receives operation information from the operation receiving unit 21, it refers to the evaluation table T1 in the storage unit 30. If the evaluation table T1 contains a record of identification information of content that is the target of the user operation indicated by the operation information, the evaluation unit 23 adds or subtracts evaluation points corresponding to the identification information according to the content of the operation information. On the other hand, if the evaluation table T1 does not contain a record of identification information of content that is the target of the user operation indicated by the operation information, the evaluation unit 23 adds a record with the identification information and evaluation points set to "zero," and adds or subtracts evaluation points for the added record according to the user operation.

[0048] For example, the evaluation unit 23 creates the evaluation table T1 based on user operations related to programming recording of content, user operations related to playing back recorded content, and user operations related to saving recorded content.

[0049] (1) Example of adding evaluation points For example, when the evaluation unit 23 receives operation information related to a recording reservation from the operation reception unit 21, it refers to the evaluation table T1 and adds "1" to the evaluation point of the content recorded by the content processing unit 22. If the content recorded by the content processing unit 22 is content recorded based on a repeated recording reservation, the evaluation unit 23 further adds "1" to the evaluation point of the content. Here, repeated recording refers to, for example, recording every week a program that is broadcast in the same broadcast time slot every week.

[0050] Furthermore, for example, when the evaluation unit 23 receives operation information related to the playback of recorded content from the operation reception unit 21, it refers to the evaluation table T1 and adds "1" to the evaluation point of the recorded content played back by the content processing unit 22. When the recorded content is played back within a period of a predetermined length L1 from the timing of recording, the evaluation unit 23 further adds "1" to the evaluation point of the recorded content. The predetermined length L1 may be one week or one month.

[0051] Also, for example, when the evaluation unit 23 receives operation information regarding the protection of recorded content from the operation receiving unit 21, it refers to the evaluation table T1 and adds "1" to the evaluation point of the recorded content for which the protection setting is turned on by the content processing unit 22.

[0052] The evaluation unit 23 may weight the added value of the evaluation points depending on the content of the user operation, and may add a value of "2" or more to the evaluation points, for example.

[0053] (2) Example of deduction of evaluation points Furthermore, for example, when the evaluation unit 23 receives operation information related to erasure of recorded content from the operation receiving unit 21, the evaluation unit 23 refers to the evaluation table T1 and subtracts "1" from the evaluation points of the recorded content to be erased by the content processing unit 22. When the recorded content to be erased by the content processing unit 22 is erased without ever being played back after being recorded, the evaluation unit 23 further subtracts "1" from the evaluation points of the recorded content.

[0054] For example, when the evaluation unit 23 receives operation information relating to the deletion of a recording reservation from the operation reception unit 21, the evaluation unit 23 refers to the evaluation table T1 and subtracts "1" from the evaluation points of the content for which the recording reservation is to be deleted by the content processing unit 22. If the content for which the recording reservation is to be deleted by the content processing unit 22 is a content for which a repeat recording reservation is to be deleted, the evaluation unit 23 further subtracts "1" from the evaluation points of the content.

[0055] Also, for example, when the evaluation unit 23 receives operation information regarding the removal of protection from the operation receiving unit 21, it refers to the evaluation table T1 and subtracts "1" from the evaluation point of the recorded content for which the protection setting is turned off by the content processing unit 22.

[0056] Furthermore, for example, if a period of a predetermined length L2 has elapsed without the content being played back after the content was recorded by the content processing unit 22, the evaluation unit 23 subtracts "1" from the evaluation points of the content. The predetermined length L2 may be one week or one month.

[0057] Furthermore, for example, when a predetermined length L3 has elapsed since the (N-1)th recorded content was played back without creating the Nth recorded content among the plurality of recorded contents repeatedly recorded by the content processing unit 22, the evaluation unit 23 subtracts "1" from the evaluation points of each of the plurality of recorded contents, where N is an integer equal to or greater than 2. The predetermined length L3 may be one week or one month.

[0058] The evaluation unit 23 may weight the subtraction value of the evaluation points according to the content of the user operation, for example, subtracting a value of "2" or more from the evaluation points. The evaluation unit 23 may also be configured not to add or subtract evaluation points. The evaluation table T1 may also be created without using part of the operation information indicating user operations related to scheduling recording of content, the operation information indicating user operations related to playing recorded content, and the operation information indicating user operations related to saving recorded content.

[0059] (Submitting evaluation information) The communication unit 24 transmits the evaluation table T1 created by the evaluation unit 23 to the server 201 outside the broadcast receiving device 101.

[0060] More specifically, the communication unit 24 acquires the evaluation table T1 from the storage unit 30 at a transmission timing according to a predetermined transmission cycle C1, and transmits the acquired evaluation table T1 and terminal information including the ID of the broadcast receiving device 101 via the network to the server 201. For example, when the communication unit 24 completes transmission of the terminal information, it erases the transmitted evaluation table T1 from the storage unit 30.

[0061] (Server configuration) 5 is a diagram illustrating a configuration of a server according to an embodiment of the present disclosure. Referring to FIG. 5, server 201 includes communication unit 41, counting unit 42, and storage unit 43. Communication unit 41, counting unit 42, and processing unit 20 may be partially or entirely realized by a processing circuit including one or more processors. Storage unit 43 may be a non-volatile memory included in the processing circuit.

[0062] The communication unit 41 acquires a plurality of evaluation tables T1 created by a plurality of broadcast receiving devices 101. More specifically, the communication unit 41 receives terminal information from each broadcast receiving device 101 via the network. Upon receiving the terminal information, the communication unit 41 outputs the received terminal information to the aggregation unit 42.

[0063] The tallying unit 42 generates a tally of the evaluation values ​​of the content based on the multiple evaluation tables T1 acquired by the communication unit 41.

[0064] 6 is a diagram illustrating an example of an aggregation table stored in a storage unit in a server according to an embodiment of the present disclosure. Referring to FIG. 6, the aggregation unit 42 creates an aggregation table T2, which is an aggregation result indicating a correspondence between content identification information and the evaluation points of the content, based on a plurality of pieces of terminal information received from the communication unit 41. The aggregation unit 42 stores the created aggregation table T2 in the storage unit 43.

[0065] More specifically, each time the tallying unit 42 receives terminal information from the communication unit 41, the tallying unit 42 acquires the evaluation table T1 from the received terminal information. Then, the tallying unit 42 adds the evaluation points in the evaluation table T1 acquired from the terminal information to the evaluation points in the tallying table T2 in the storage unit 43.

[0066] For example, the aggregation unit 42 decreases the evaluation points of a record in the aggregation table T2 according to the time that has elapsed since the record was added to the aggregation table T2, thereby correcting the evaluation points of the content according to the time that has elapsed since the content was broadcast.

[0067] (Request for tally results) 3, the communication unit 24 in the processing unit 20 of the broadcast receiving device 101 transmits a recording list Rr that lists recorded content to the server, and receives from the server 201 the results of tallying the evaluation values ​​of the content indicated in the transmitted recording list Rr, the tallying results being based on multiple evaluation tables T1 created by the multiple broadcast receiving devices 101. The recording list Rr is an example of a content list.

[0068] More specifically, the communication unit 24 acquires identification information of all recorded content stored in the HDD 40 from the recording DB 31 at an acquisition timing according to a predetermined acquisition period C2. The acquisition period C2 may be the same as or different from the transmission period C1 described above. The communication unit 24 generates a recording list Rr indicating a list of the acquired identification information, and transmits a counting result request including the generated recording list Rr to the server 201 via the network. Note that the communication unit 24 may also be configured to generate a recording list Rr indicating identification information of some of the recorded content among all the recorded content, and transmit a counting result request including the generated recording list Rr to the server 201 via the network.

[0069] 5 again, the communication unit 41 in the server 201 receives the tally result request from the broadcast receiving device 101 via the network. The communication unit 41 transmits the tally result created by the tally unit 42 to the broadcast receiving device 101 in response to the received tally result request.

[0070] For example, the communication unit 41 transmits the aggregation result of the evaluation values ​​of the content indicated by the recording list Rr included in the aggregation result request to the broadcast receiving device 101 that sent the aggregation result request. More specifically, the communication unit 41 extracts records corresponding to the identification information included in the recording list Rr from among the records in the aggregation table T2 in the storage unit 43. The communication unit 41 generates an aggregation table T2A consisting of the extracted records, and transmits an aggregation result response including the generated aggregation table T2A to the broadcast receiving device 101 via the network.

[0071] 3, communication unit 24 receives the tallying result response from server 201 via the network, and acquires tallying table T2A from the received tallying result response. Communication unit 24 outputs the acquired tallying table T2A to notification unit 25.

[0072] The notification unit 25 notifies the user based on the tallying table T2A received by the communication unit 24.

[0073] 7 is a diagram illustrating an example of a content selection screen displayed by a notification unit in a broadcast receiving device according to an embodiment of the present disclosure. Referring to FIG. 7, notification unit 25 receives predetermined operation information from operation reception unit 21 and generates content selection screen G1 indicating the correspondence between the content titles and identification information of recorded content in HDD 40 and the evaluation points of the recorded content indicated in tally table T2A. Notification unit 25 then performs processing to display the generated content selection screen G1 on display device 111.

[0074] 8 is a diagram illustrating another example of a content selection screen displayed by a notification unit in a broadcast receiving device according to an embodiment of the present disclosure.
