The specifying unit specifies the viewing status of the program recommended by the recommendation unit based on the viewing history, and the selecting unit specifies that the recommended program is not viewed, A recommendation method different from the recommendation method recommending the program may be selected.
The recommendation method includes a second method for recommending a program similar to a program that the user has watched in the past, and the selection unit starts using the program recommendation device to select a program. If the specifying unit specifies that the situation is not started, the second method may be selected when the amount of the viewing history is a predetermined amount or more.

  The recommendation method includes a third method for recommending a program based on the similarity of a plurality of users, and the selection unit recommends the program based on the second method. In the case, the third method may be selected when the specifying unit specifies that the program recommended based on the second method is not viewed with reference to the viewing history.

The selection unit identifies a recommended method that is relatively likely to be viewed by the recommended program based on the viewing history after selecting each of a plurality of recommended methods, and selects the recommended method. May be.
The selection unit may select a recommendation method based on a change in a broadcast program.

  The program recommendation method according to the second aspect of the present invention includes a step of identifying a viewing situation of the user's program based on a viewing history of the user's program executed by a computer, and based on the identified viewing situation. , Selecting one of a plurality of recommendation methods for recommending a program, and recommending a program based on the selected recommendation method.

[Outline of Program Recommendation Device 1]
FIG. 1 is a diagram showing an outline of a program recommendation device 1 according to the present embodiment. The program recommendation device 1 is a set-top box that is provided at the home of a user who uses cable television, for example, and receives broadcast signals such as cable television broadcasting and terrestrial digital television broadcasting.

  The program recommendation device 1 receives various broadcast signals to acquire program content (hereinafter simply referred to as “program”) broadcasted by a broadcasting station or a cable television operator, and receives a television set connected to itself. It is displayed on the display 2 such as a machine. It is assumed that the user who uses the program recommendation device 1 includes a family who lives in the place where the program recommendation device 1 is installed. For example, when the program recommendation device 1 is installed in a house of a family of four, the user is a family of four.

In the present embodiment, the program recommendation device 1 identifies the viewing status of the user's program based on the viewing history of the user's program ((1) in FIG. 1). Here, the viewing status includes a usage status of the program recommendation device 1 and a status indicating whether or not the user has watched the program. The program recommendation device 1 selects one of a plurality of recommendation methods for recommending a program based on the specified viewing situation ((2) in FIG. 1). The program recommendation device 1 identifies a recommended program to be recommended to the user based on the selected recommendation method, and displays the recommended program when the menu screen is displayed on the display 2 ((3) in FIG. 1). .
By doing in this way, the program recommendation apparatus 1 can increase the variation of the recommended program shown with respect to a user.
Hereinafter, the configuration of the program recommendation device 1 will be described.

[Configuration Example of Program Recommendation Device 1]
FIG. 2 is a diagram illustrating a configuration of the program recommendation device 1 according to the present embodiment.
The program recommendation device 1 includes an input unit 11, a communication unit 12, a storage unit 13, and a control unit 14.

The input unit 11 is, for example, a button or a remote control provided in the program recommendation device 1 and accepts an operation input from a user of the program recommendation device 1.
The communication unit 12 is, for example, a tuner, and acquires a program corresponding to the broadcast signal by receiving various broadcast signals. The communication unit 12 communicates with various servers via a communication network such as the Internet.

  For example, the communication unit 12 receives an electronic program guide from a distribution server that distributes an electronic program guide (EPG) through a communication network. The electronic program guide includes program schedules for each channel, program genres, and explanation information for explaining the contents of the programs. The communication unit 12 communicates with the display 2 and also communicates with a recording device (not shown) that records a program. The recording device accepts a recording reservation for a program from the user of the program recommendation device 1 and reserves the program according to the reservation.

  The storage unit 13 is, for example, a ROM and a RAM. The storage unit 13 stores various programs for causing the program recommendation device 1 to function. For example, the storage unit 13 stores a program recommendation program that causes the control unit 14 of the program recommendation device 1 to function as a storage control unit 141, a specifying unit 142, a selection unit 143, a recommendation unit 144, and an erasing unit 145, which will be described later.

  Here, the program recommendation program includes programs corresponding to a plurality of recommendation methods for recommending a program to the user of the program recommendation device 1. Here, the plurality of recommendation methods include a first method, a second method, and a third method. The first method is a method in which a program provider (for example, a cable television operator or a broadcaster) recommends a program. The second method is a method for recommending a program similar to a program viewed by the user in the past based on viewing history information. The third method is a method for recommending a program based on the similarity of a plurality of users who use different program recommendation devices 1. Details of these methods will be described later.

  In addition, the storage unit 13 stores the electronic program guide received by the communication unit 12 and viewing history information indicating a history of programs viewed by the user. FIG. 3 is a diagram illustrating an example of viewing history information. As shown in FIG. 3, the viewing history information includes the viewing start time indicating the time when the user started viewing the program, the viewing end time indicating the time when the user finished viewing the program, and the program viewed by the user. It includes a corresponding channel, a program ID for identifying a program viewed by the user, and a viewing type. The viewing type is information indicating whether viewing of a program is viewing of a program being broadcast or viewing of a recorded program.

  The control unit 14 is a CPU, for example. The control unit 14 controls functions related to the program recommendation device 1 by executing various programs stored in the storage unit 13. The control unit 14 includes a storage control unit 141, a specifying unit 142, a selection unit 143, a recommendation unit 144, and an erasing unit 145.

  The storage control unit 141 causes the storage unit 13 to store viewing history information corresponding to the program viewed by the user. Specifically, when a program is selected by the selection operation, the storage control unit 141 sets the selected time as the viewing start time, and identifies the channel corresponding to the selected program and the selected program. The program ID and the viewing type are specified. When the input control unit 11 receives an operation for switching channels or an operation for turning off the power of the program recommendation device 1, the storage control unit 141 determines that the viewing of the program that has been viewed by the user has ended. The time when the operation is accepted is set as the viewing end time of the program. Then, the storage control unit 141 stores the viewing start time, the viewing end time, the channel, the program ID, and the viewing type in the storage unit 13 in association with each other as viewing history information.

  The specifying unit 142 specifies the viewing status of the user's program based on the viewing history of the user. Specifically, the specifying unit 142 determines whether or not the amount of viewing history information stored in the storage unit 13 is less than a predetermined amount every predetermined time (for example, every other day). Whether the user has started using the program recommendation device 1 and started watching the program is specified. When the amount of viewing history information is less than a predetermined amount, the identifying unit 142 identifies that the user has started using the program recommendation device 1 and started viewing the program, and the amount of viewing history information is greater than or equal to the predetermined amount. In some cases, it is specified that the program is not starting to be viewed. Here, the predetermined amount is, for example, the amount of viewing history for one month. However, the predetermined amount is not limited to this as long as it is an amount that can appropriately analyze programs that the user has viewed in the past.

  Further, the specifying unit 142 specifies the viewing status of the program recommended by the below-described recommendation unit 144 based on the viewing history information. For example, the storage unit 13 stores a program ID for identifying a program recommended by the recommendation unit 144, and the specifying unit 142 determines whether the program ID is included in the viewing history information. Thus, it is specified whether or not the program recommended by the recommendation unit 144 has been viewed. The identifying unit 142 may determine that the recommended program is not viewed when the ratio between the number of recommended programs and the number of the programs included in the viewing history information is less than a predetermined value. Good.

The selection unit 143 selects one of a plurality of recommendation methods for recommending a program based on the viewing situation of the user's program.
Specifically, the selection unit 143 selects the first method when the specifying unit 142 specifies that the user's program viewing status is the status where the program recommendation device 1 starts to be used and the program starts to be viewed. To do. The selection unit 143 selects the second method when the specifying unit 142 specifies that the viewing status of the program by the user is not the status in which the program recommending apparatus 1 is started and the user has started viewing the program.

  When the viewing situation of the user's program is a situation where the use of the program recommendation device 1 is started and the viewing of the program is started, the amount of viewing history information stored in the storage unit 13 is small, and the user has It is not possible to properly analyze based on the program watched. On the other hand, the program recommendation device 1 selects the first method in which the program providing side recommends the program when the user starts using the program recommendation device 1 and starts watching the program. Therefore, a program can be recommended even when the amount of viewing history information is small.

When the specifying unit 142 specifies that the program recommended by the recommendation unit 144 is not viewed, the selection unit 143 selects a recommendation method different from the recommendation method that recommended the program. Specifically, when the recommendation unit 144 recommends a program based on the second method, the selection unit 143 refers to the viewing history information and views the program recommended based on the second method. If the specifying unit 142 specifies that the information is not present, the third method is selected.
In this way, the program recommendation device 1 can improve the program recommendation effect by switching the recommendation method to the third method when the effect of program recommendation by the second method is small.

Note that the selection unit 143 identifies a recommended method with a relatively high possibility of viewing the recommended program based on the viewing history after selecting each of the plurality of recommended methods, and selects the recommended method. May be. Specifically, the selection unit 143 determines that a predetermined time has elapsed since the recommendation method was switched from the second method to the third method, or a predetermined time has elapsed since the recommendation method was switched from the first method to the second method. However, if the system has not been switched to the third system, the ratio of the viewed program to the number of programs recommended by each recommended system is calculated based on the viewing history information. Then, the selection unit 143 identifies the recommendation method having the highest ratio as a recommendation method with a relatively high possibility of viewing the recommended program, and selects the recommendation method.
By doing in this way, the program recommendation apparatus 1 can recommend a program based on the most effective recommendation method among a plurality of recommendation methods.

  The selection unit 143 may select a recommendation method based on a change in a broadcast program. For example, a broadcast program may change at a program reorganization period such as a season change or a year change. On the other hand, the selection unit 143 refers to the electronic program guide stored in the storage unit 13 and periodically broadcasts a program (for example, a program broadcast on a predetermined day of the week, It is determined whether the program is being reorganized by determining whether the title of the program broadcast on weekdays has changed to another title. Then, the selection unit 143 selects the second method when it is determined that it is the program reorganization period, and selects the third method when it is determined that it is not the reorganization period.

  In this way, the program recommendation device 1 newly broadcasts by selecting the second method that recommends a program similar to a program that the user has viewed in the past based on the viewing history information in the program reorganization period. Of the displayed programs, a program similar to a program that the user has watched in the past can be presented as a recommended program.

  In addition, the program recommendation device 1 selects a third method for recommending a program based on the similarity of a plurality of users who use different program recommendation devices 1 at a time not in the program reorganization period. A program viewed by another user similar to the user can be presented as a recommended program. Thereby, when the same program is broadcast regularly, the new program which is not based on a user's past viewing tendency can be shown to the user concerned.

  The recommendation unit 144 selects a program based on the recommendation method selected by the selection unit 143 in response to the user turning on the power of the program recommendation device 1 or performing a menu screen display operation using the input unit 11. Recommendation to.

  When the first method is selected by the selection unit 143, the recommendation unit 144 indicates a recommended program corresponding to the first method in response to the menu screen display operation performed by the input unit 11. An acquisition request for recommended program information is transmitted to a first distribution device (not shown) that distributes information. The first distribution device stores recommended program information indicating a recommended program that is selected by the program provider and recommended to the user of the program recommendation device 1. The first distribution device transmits recommended program information to the program recommendation device 1 in response to receiving a request for obtaining recommended program information from the program recommendation device 1.

  When the recommended program information is received from the first distribution device, the program recommendation device 1 causes the display 2 to display a menu screen including information indicating the recommended program included in the recommended program information (for example, program introduction information). FIG. 4 is a diagram illustrating an example of a menu screen displayed on the display 2. In the example shown in FIG. 4, it can be confirmed that thumbnail images of recommended programs A, B, C, and D are displayed.

  The first distribution device accepts a popular program such as a high audience rating in each of a plurality of genres as a recommended program recommended to the user from the program providing side, and associates the recommended program with the genre. May be remembered. In this case, the first distribution device may accept a genre in which the user is interested in advance from the user via the program recommendation device 1.

  Then, in response to receiving the recommended program information acquisition request from the program recommendation device 1, the first distribution device selects a program corresponding to the genre received in advance from the user of the program recommendation device 1 as a recommended program, The recommended program information indicating the recommended program may be transmitted to the program recommendation device 1. In addition, the first distribution device does not accept a recommended program from the program providing side, and is presented in a program with a high average audience rating, a program with high topicality in SNS (Social Networking Service), or a curation service. The program may be specified and the program may be selected as the recommended program.

  When the second method is selected by the selection unit 143, the recommendation unit 144 specifies the genre to which the program that the user has viewed in the past belongs based on the viewing history information. Specifically, the recommendation unit 144 specifies the viewing degree of the user's program for each day of the week, time zone, and genre to which the program belongs based on the viewing history information, and based on the viewing degree, the day of the week and the time The recommended genre for each band is specified.

  Then, the recommendation unit 144 refers to the electronic program guide stored in the storage unit 13 in response to the menu screen display operation performed by the input unit 11, and sets the day of the week and the time zone to which the current time belongs. On the other hand, a program corresponding to the specified genre is specified as a recommended program. The program recommendation device 1 causes the display 2 to display a menu screen including information indicating the specified recommended program.

  In addition, when the 2nd system is selected, although the recommendation part 144 specified the recommended program based on the electronic program guide, it is not restricted to this. For example, a second distribution device (not shown) that manages meta information such as a program genre and program content and transmits recommended program information indicating a recommended program corresponding to the genre in response to reception of the genre. It may be provided. And the recommendation part 144 transmits the information which shows the specified genre to a 2nd delivery apparatus, and receives the recommended program information which shows the recommended program corresponding to the specified genre from the said 2nd delivery apparatus, The said genre A recommended program corresponding to may be specified.

  Further, when the second method is selected, the recommendation unit 144 refers to the electronic program guide and identifies a program corresponding to the genre specified for the day of the week and the time zone to which the current time belongs as a recommended program. However, it is not limited to this. For example, when the second method is selected, the recommendation unit 144 specifies a program viewed by the user based on the viewing history information, and uses the program information to explain the content of the program included in the electronic program guide. A keyword corresponding to may be extracted. Keywords are sports teams, celebrities, place names, and the like. And the recommendation part 144 may specify the program which the user does not view among the programs corresponding to the said keyword in an electronic program guide as a recommended program.

  When the third method is selected by the selection unit 143, the recommendation unit 144 identifies the user profile information input in advance by the user of the program recommendation device 1 and stored in the storage unit 13, and the program recommendation device 1 The device ID to be transmitted is transmitted to a third distribution device (not shown) that distributes recommended program information indicating a recommended program corresponding to the third method. Here, the user's profile information includes, for example, information indicating the user's age, family structure, and genre that the user is interested in. Further, when the third method is selected, the recommendation unit 144 periodically transmits the viewing history information stored in the storage unit 13 and the device ID to the third distribution device.

The third distribution device stores the device ID received from each of the plurality of program recommendation devices 1, the user profile information, and the viewing history information in association with each other.
When the third method is selected, the recommendation unit 144 receives a device ID for identifying the program recommendation device 1 and an acquisition request for recommended program information in response to the menu screen display operation performed by the input unit 11. Are transmitted to the third distribution device.

  When the third distribution device receives the device ID and the acquisition request for the recommended program information, the third distribution device specifies the profile information of the user associated with the device ID, and has a profile similar to the profile indicated by the profile information. Identify multiple users. Based on the viewing history information of the other plurality of specified users, the third distribution device requests acquisition of recommended program information from among programs with a relatively high ratio of viewing by the other plurality of users. A program that is not viewed by the user of the transmitted program recommendation device 1 is selected as a recommended program. Then, the third distribution device transmits recommended program information indicating the selected recommended program to the program recommendation device 1 that has transmitted the acquisition request for the recommended program information. When the recommended program information is received from the third distribution device, the program recommendation device 1 causes the display 2 to display a menu screen including information indicating the recommended program included in the recommended program information.

  In addition, although the 3rd delivery apparatus specified the recommendation program based on the viewing-history information of several other users with a similar profile as a user, it is not restricted to this. For example, the third distribution device identifies viewing history information of another user similar to the viewing history information of the user, and among the programs included in the identified viewing history information, a program that the user has not viewed as a recommended program. You may choose. In this case, the third distribution device identifies the viewing tendency of the user for each day of the week, time of day, and length of broadcast time of the program based on the user's viewing history information, and broadcasts the day of the week, time of day and program. You may identify the other user with a similar viewing tendency for every length of time. Then, the third distribution device may select the recommended program based on the viewing history information of the identified other user.

  The erasure unit 145 erases, from the storage unit 13, the viewing history information stored in a predetermined time before the current time (for example, one month) among the viewing history information stored in the storage unit 13. By doing so, the program recommendation device 1 can recommend a program based on the viewing history of the program that the user has recently viewed when recommending the program by the second method.

[Flow of processing in program recommendation device 1]
Next, a flow of processing for selecting a recommendation method in the program recommendation device 1 will be described. FIG. 5 is a flowchart showing a flow of processing for selecting a recommendation method in the program recommendation device 1.

  First, the specifying unit 142 determines whether or not the amount of viewing history information stored in the storage unit 13 is less than a predetermined amount (S1). If the identifying unit 142 determines that the amount of viewing history information is less than the predetermined amount, it moves the process to S2, and moves to S3 if it determines that the amount of viewing history information is greater than or equal to the predetermined amount.

In S2, the selection unit 143 selects the first method as the recommendation method. After selecting the first method, the selection unit 143 moves the process to S1.
In S3, the selection unit 143 selects the second method as the recommendation method.

  In S4, the specifying unit 142 determines whether or not the recommended program recommended by the second method is viewed with reference to the viewing history information. If the identifying unit 142 determines that the recommended program is being viewed, the specifying unit 142 re-executes S4. If the determining unit 142 determines that the recommended program is not being viewed, the process proceeds to S5.

In S5, the selection unit 143 selects the third method as the recommendation method.
Subsequently, the selection unit 143 calculates a viewing ratio corresponding to each of the plurality of recommended methods in response to the elapse of a predetermined time after the third method is selected in S5 (S6).
Subsequently, the selection unit 143 selects a recommendation method having the highest viewing ratio based on the calculation result in S6 (S7).

  Note that the selection unit 143 may repeatedly select the recommendation method after the recommendation method is selected in S7. In this case, after the recommendation method is selected, the specifying unit 142 determines whether the recommended program recommended by the recommendation method is being viewed. Then, the selection unit 143 may select another recommended method in response to determining that the recommended program recommended by the recommendation method is not viewed.
