[Overview of Cooperation System S]
First, an outline of a cooperative system S including the receiver 1 of the present invention will be described with reference to FIG. As shown in FIG. 1, the cooperation system S includes a receiver 1, a management server 2, a distribution server 3, and a content server 4.

The receiver 1 is a set-top box that receives a broadcast signal transmitted from the distribution server 3 and converts it into a viewable signal. The receiver 1 may be a set-top box integrated with the display device, or may be a set-top box provided separately from the display device. In the present embodiment, for the sake of simplicity, a description will be given of a receiver 1 in which a display device and a set-top box are integrated as an example.
The receiver 1 is communicably connected to an external device via a network such as the Internet or a cable network. In the present embodiment, the receiver 1 is communicably connected to the management server 2, the distribution server 3, and the content server 4.

The management server 2 is a server that controls services in the cooperation system S (cooperation service between broadcasting and communication). The management server 2 is communicably connected to the content server 4 via a network, and receives registration of a broadcast program that can be viewed in the service from the content server 4 or a Web content corresponding to a channel corresponding to the broadcast program. The registered channel-Web content correspondence is provided to the receiver 1.
The receiver 1 refers to this correspondence relationship, grasps the Web content associated with the broadcast program being viewed, and acquires the Web content from the content server 4.

  The distribution server 3 is managed by a distribution company that distributes a broadcast signal, and transmits a broadcast signal corresponding to a broadcast program using broadcast equipment. The broadcast facility is a broadcast facility for cable television broadcast or IP television broadcast, and transmits a broadcast signal via an optical cable or the like.

The content server 4 is a server that provides Web content to be displayed on the receiver 1 together with a broadcast program, and for each channel managed by a program supplier that supplies a broadcast program corresponding to a channel available in the service. It includes a content server 4 and a content server 4 for a distribution company managed by a distribution company that distributes a broadcast signal corresponding to a broadcast program.
As an example, when the cooperative system S is applied to a cable TV system, each cable TV station corresponds to a distribution company, and a broadcast station that provides a broadcast program corresponding to each channel available in the cable TV station is a program. Equivalent to a supplier.

  In the cooperation system S having the above configuration, while viewing the broadcast program on the receiver 1, the Web content associated with the broadcast program (channel) being viewed is also provided. Specifically, as shown in FIG. 1, the receiver 1 displays a broadcast program in a part of the display area, and displays Web contents such as a first content and a second content in another part.

  Note that the first content is a Web content provided from the channel content server 4, and the second content is a Web content provided from the distribution server content server 4. That is, in the cooperative system S, when the user using the receiver 1 is watching a broadcast program of a certain channel on the receiver 1, the Web content corresponding to the channel is provided as the first content. Web content corresponding to the distribution company that provides the broadcast program is provided as the second content.

  Specifically, the receiver 1 grasps the content server 4 for the channel corresponding to the broadcast program being viewed on the basis of the correspondence relationship (channel-Web content) acquired from the management server 2, and From the first content. In addition, the content server 4 obtains the second content from the content server 4 based on the content server 4 corresponding to the distribution company from the distribution company to which the user has a contract.

As described above, the cooperative system S provides a cooperative service between broadcasting and communication to a user using the receiver 1. In this cooperative service, the receiver 1 obtains Web content corresponding to a broadcast program by executing an application program, and receives the cooperative service even if it is not a dedicated receiver like a hybrid cast broadcast. be able to.
Hereinafter, details of the cooperative system S including the receiver 1 of the present invention will be described.

[Example of system aspect of cooperation system S]
FIG. 2 shows an example of a preferable system mode of the above-described cooperation system S. FIG. 2 is a diagram illustrating an example of a system mode of the cooperation system S. As shown in FIG. 2, the cooperation system S of the present invention can be suitably used in, for example, a cable television system.

In a cable TV system, a cable TV station and each user's home are connected by an optical cable, a coaxial cable, or the like, and the cable TV station receives a broadcast wave transmitted from a program provider (broadcasting station) and distributes the broadcast wave to each user's home. The user watches the broadcast program. Here, a network formed by an optical cable connecting the cable television station and each user's home is called a cable network.
In a cable television system, a complex service including an Internet connection, a telephone, and the like is usually provided in addition to a television broadcast. Internet connection in a cable television system is established by accessing the Internet from a cable network.

  When the cooperative system S of the present invention is applied to such a cable television system, the receiver 1 corresponds to a television receiver provided in a user's home, and each cable television station transmits to a distribution company that manages the distribution server 3. Equivalent to. For example, the receiver 1 of the user home A receives the distribution of the broadcast program from the distribution company “cable station A”, and the receiver 1 of the user home C receives the distribution of the broadcast program from the distribution company “cable station B”. Will receive it.

  The management server 2 and the content server 4 for each channel are servers on the Internet, and are installed outside the cable network. On the other hand, the content server for the distribution company may be installed inside the cable network or outside the cable network because the distribution company (cable TV station) manages the content server.

  The example of the system mode of the cooperation system S is shown in FIG. Note that the example of the embodiment shown in FIG. 2 is merely an example, and the cooperative system S of the present invention uses a television system other than a cable television system, that is, a normal television broadcast that provides a broadcast program using radio waves or the Internet. The present invention can also be applied to a television system such as an IP broadcast that provides a broadcast program via the Internet.

[Functional Configuration of Receiver 1 and Management Server 2]
Next, with reference to FIG. 3 to FIG. 8, a basic configuration of the receiver 1 and the management server 2 constituting the cooperation system S of the present invention will be described. FIG. 3A is a block diagram illustrating a functional configuration of the management server 2, and FIG. 3B is a block diagram illustrating a functional configuration of the receiver 1.

As illustrated in FIG. 3A, the management server 2 includes a storage unit 21, a communication unit 22, and a control unit 23.
The storage unit 21 includes, for example, a ROM and a RAM. The storage unit 21 stores various programs and various information for causing the management server 2 to function. Here, part of the information stored in the storage unit 21 is shown in FIG. As shown in FIG. 4A, the storage unit 21 stores various types of information regarding a provider URL, a correspondence relationship, an initial channel, and the like for each distributor.

  The provider URL is location information indicating the location of the content server 4 for the distributor. In the example shown in FIG. 4, the location of the content server 4 managed by the cable station A is the business operator URL “URL1”, and the location of the content server 4 managed by the cable station B is the business operator URL “URL2”. I understand. As will be described later, the receiver 1 acquires the second content (see FIG. 1) using the provider URL.

  The correspondence is information that defines a channel and Web content to be linked in the link system S, and includes an available channel and location information (CH_URL) indicating the location of the Web content corresponding to the channel. Here, the broadcast program distributed to the receiver 1 differs depending on the distributor. The available channel is information that defines a channel number that can use the cooperative service in the cooperative system S for each distribution company. In the example shown in FIG. 4, it is understood that “1CH, 2CH, 3CH...” Is available in the cable station A, while “2CH, 3CH...” Is available in the cable station B. As will be described later, the receiver 1 obtains the first content (see FIG. 1) that cooperates with the broadcast program being viewed using the channel-Web content correspondence.

Generally, a broadcast program corresponding to a channel differs depending on a broadcast time zone even if the channel is the same. Therefore, when linking a broadcast program with Web content, a broadcast program (broadcast time zone) is used instead of each channel. It is necessary to set the correspondence with the Web content for each. In this regard, in FIG. 4A, the illustration is simplified and a common URL is associated with one channel. However, in practice, the storage unit 21 stores one channel for each time zone. Each stores a different URL (that is, stores the URL of the Web content corresponding to each broadcast program).
Further, as described later, in the cooperation system S, a broadcast program and Web contents are linked in a one-to-many relationship. Therefore, the storage unit 21 stores a plurality of URLs in association with each broadcast program.

The initial channel is information indicating a channel number selected at the time of starting an application for realizing the cooperation system S. As shown in FIG. 4A, the initial channel is set for each distribution company, and a different channel is set for a fixed period (one week). The cooperative system S guides the user of the receiver 1 to a broadcast program corresponding to the channel by setting an initial channel when the application is activated in the receiver 1.
In the example shown in FIG. 4A, when the above-described application is started in the receiver 1 that receives the distribution of the broadcast program from the cable station A, the broadcast program corresponding to “1CH” is activated in the first week of April at the time of the start. Are displayed, and a broadcast program corresponding to “2CH” is displayed in the second week of April.

Further, as shown in FIG. 4B, the storage unit 21 stores, for each program supplier, introduction information for introducing a broadcast program of the program supplier. In the cooperative system S, available channels are defined for each distributor, and these channels include channels that can be viewed by making a special contract. For this reason, depending on the contract content of the receiver 1 (user), the receiver 1 may not be able to view even the available channel specified for each program supplier. The introduction information is video, audio, or text information for introducing the channel to a user who cannot view. The storage unit 21 may store moving image information or the like itself as introduction information, or may store location information (URL) indicating the location of the introduction information.
It is preferable that the above-mentioned initial channel is set so as to avoid a channel that cannot be viewed unless such a special contract is made.

  These pieces of information shown in FIG. 4 are stored in the storage unit 21 of the management server 2 with a registration operation received from a program supplier (broadcasting station) and a distribution company (cable television station).

Returning to FIG. 3A, the communication unit 22 is connected to an external device via a predetermined communication line, and performs predetermined communication with the external device. As an example, the communication unit 22 is communicably connected to the receiver 1, the program provider, and the distribution company via a cable network or the Internet.
The control unit 23 is configured by, for example, a CPU. The control unit 23 controls various functions of the management server 2 by executing various programs stored in the storage unit 21. For example, the control unit 23 receives registration of the above-described URL or the like from the program supplier and the distribution business via the communication unit 22 and provides the information to the receiver 1 as necessary.

Subsequently, as illustrated in FIG. 3B, the receiver 1 includes a storage unit 11, a display unit 12, an operation unit 13, a communication unit 14, and a control unit 15.
The storage unit 11 includes, for example, a ROM and a RAM. The storage unit 11 stores various programs and various information for causing the receiver 1 to function. For example, the storage unit 11 stores an application program for implementing a cooperation service provided by the cooperation system S. Further, the storage unit 11 stores various information acquired from the management server 2 or the content server 4.

The display unit 12 is configured by a liquid crystal display, an organic EL (Electro-Luminescence) display, or the like, and displays a broadcast program or Web content under the control of the control unit 15.
The operation unit 13 is configured by, for example, a button, a contact sensor arranged to be superimposed on the display unit 12, and receives an operation input from a user of the receiver 1. In the case of the present embodiment, a remote controller for television used for channel selection and the like corresponds to the operation unit 13.

  The communication unit 14 is connected to an external device via a predetermined communication line, and performs predetermined communication with the external device. As an example, the communication unit 14 receives a broadcast signal transmitted from the distribution server 3 via a broadcast network or a cable network. The communication unit 14 is communicably connected to the management server 2 and the content server 4 via a cable network or the Internet, receives each piece of information such as the above-described correspondence from the management server 2, and To receive.

  The control unit 15 is configured by, for example, a CPU. The control unit 15 performs various functions including a basic function 151, an adjustment function 152, an additional function 153, and an additional function 154 according to the above-described application program stored in the storage unit 11, and cooperates with the broadcast program and the Web content. Implement a cooperative service.

The basic function 151 is a basic function for realizing a cooperative service. When linking a broadcast program with Web content, the receiver 1 needs to specify Web content to be linked with the broadcast program. In the hybrid cast broadcast, the receiver 1 analyzes the broadcast signal and reads out the AIT to identify the Web content. However, since the broadcast signal needs to be analyzed, only the dedicated receiver can cooperate. You cannot enjoy the service.
In this regard, the basic function 151 is a function of acquiring necessary information by accessing the management server 2 via a network, and is a function that can be exhibited by a network-compatible receiver.

The adjusting function 152 is a function of adjusting the size of the broadcast program and the size of the Web content when displaying the broadcast program and the Web content at the same time on the display unit 12. In addition, the additional functions 153 and 154 are performed together with the basic function 151 to further improve the benefits of the user (receiver 1) who enjoys the cooperative service and the program provider (broadcasting station) that provides the cooperative service. Function.
Details of the basic function 151, the adjustment function 152, and the additional functions 153 and 154 will be described later.

[Configuration of Display Unit 12 of Receiver 1]
Subsequently, the configuration of the display unit 12 of the receiver 1 (that is, the “display device” of the present invention) will be described with reference to FIGS.
When the above-described application is executed, a display screen displayed on the display unit 12 by the browser 120 controlled based on the application is configured. As shown in FIG. 5A, the browser 120 divides the display area of the display unit 12 into an area including a first area 121, a second area 122, a third area 123, and a fourth area 124.

The first area 121 is an area for displaying a broadcast program distributed from the distribution server 3, and the second area 122 is an area for displaying Web contents associated with the broadcast program. Further, the third area 123 is an area for displaying Web contents according to a distribution company that distributes a broadcast signal, and the fourth area 124 is an area for displaying an operation menu or the like in a cooperative service. The first to fourth regions 121 to 124 are provided so that they do not overlap with each other.
The first area for displaying the broadcast program is preferably an area obtained by reducing the entire display area of the display unit 12 by a predetermined ratio in order to match the aspect ratio of the display unit 12.

In the browser 120, the display screen is hierarchized into a plurality of layers, and at least the first area 121 is arranged in a layer higher than the second area 122 and the third area 123. In the example shown in FIG. 5B, the display screen is hierarchized into a first layer L1 and a second layer L2 lower than the first layer L1, and the first area 121 and the fourth area 124 are divided into the first layer L1. , And the second area 122 and the third area 123 are arranged in the second layer L2. Thus, a broadcast program can be displayed with priority over Web content.
Note that, in FIG. 5B, the region 121A is arranged on the second layer L2. This area 121A is used when displaying a moving image content instead of a broadcast program. When displaying a broadcast program on the receiver 1, the broadcast program is displayed in the first area 121 of the first layer L <b> 1. On the other hand, when displaying moving image content, the display of the first area 121 is stopped and the second program is displayed. Moving image content may be displayed in the area 121A of the layer L2.

[Display Example of Second Region 122]
Subsequently, a display example of the second area 122 will be described with reference to FIG. In the second area 122, different Web contents are displayed according to the channel selected by the user. More specifically, in the second area 122, Web contents (Web page 203 or moving image introduction page 204) acquired based on the channel-Web content correspondence relationship acquired from management server 2 are displayed.
In the second area 122, a tab 201 is provided, and a Web page 203 and a moving image introduction page 204 can be switched. In FIG. 6A, since the Web is selected by the tab 201, the Web page 203 is displayed in the second area 122. In FIG. 6B, since the moving image is selected by the tab 201, the Web page 203 is displayed. In the second area 122, a moving image introduction page 204 is displayed.

  A program provider that provides a broadcast program may associate both the Web page 203 and the moving image introduction page 204 with the broadcast program, or may associate only one of them. Also, a tab 201 may be provided in the second area 122 for a broadcast program associated with both, and the tab 201 may not be provided for a broadcast program associated with only one of them. .

  As shown in FIG. 6A, the Web page 203 includes a tab 202, and a plurality of (four) pages can be switched. As the plurality of pages, for example, a main page for providing information related to a broadcast program, an SNS page for communicating with the broadcast program, a column page for providing a special column of the broadcast program, and a present corresponding to the broadcast program are provided. A page such as a program present page can be considered. The plurality of pages are switched by tabs 202 provided corresponding to the four-color buttons provided on the remote controller of the receiver 1, and the page corresponding to the tab corresponding to the button operated by the user is displayed in the second area. Displayed at 122.

In a state where the web page 203 is displayed in the second area 122 and a hyperlink provided in the web page 203 is selected, the hyperlink provided in the first area 121 is independent of the broadcast program being displayed in the first area 121. The display of the second area 122 is switched according to the hyperlink.
When a moving image or the like is reproduced in the second area 122 due to the transition of the Web page, arbitrary control is performed on the sound included in the moving image. Specifically, while outputting the sound of the broadcast program in the first area 121, the sound of the moving picture in the second area 122 may not be output. May be output, or both sounds may be output. When outputting the sound of the moving image, the display of the first area 121 may be stopped. How to control the audio output can be set for each channel (more specifically, a broadcast program), and is managed by the management server 2. The receiver 1 performs predetermined audio output control for each channel (broadcast program) by acquiring the setting information from the management server 2.

  As shown in FIG. 6B, a list of videos to be introduced is displayed on the video introduction page 204. Some program providers who provide broadcast programs distribute their past broadcast programs as moving images, and the moving image introduction page 204 introduces such past broadcast programs. When the user selects a moving image on the moving image introduction page 204, the display of the broadcast program in the first area 121 stops, and the selected moving image is displayed in the area 121A arranged behind the first area 121.

Subsequently, a display example of the third area 123 will be described with reference to FIG. In the third area 123, Web content corresponding to the distribution company (cable TV station) with which the receiver 1 (user) has contracted is displayed. In other words, when the distribution company subscribed to the receiver 1 is the same, the same Web content is displayed in the third area 123 regardless of the selected channel.
Although the details will be described later, the basic function 151 of the receiver 1 accesses the management server 2 using the business code for identifying the distribution business contracted by itself when the application is activated, and The Web content corresponding to the provider URL (see FIG. 4) of the distributor identified by the code is acquired. The Web content acquired based on the provider URL is displayed as a Web page 211 in the third area 123.

  In addition, as such Web contents, in addition to Web contents that introduce information that can be provided regardless of the period, such as support information, there is a limited time period such as campaign information and present information currently being performed by the distribution company. Web contents for introducing information can be adopted, and these Web contents are displayed as a Web page 211 in the third area 123.

[Display Example of Fourth Area 124]
Subsequently, a display example of the fourth area 124 will be described with reference to FIG. The fourth area 124 displays the operation menus 221 and 222 of the cooperative service, the number of the currently viewed channel, and the like. The operation menu 221 is an operation unit for adjusting the size of the first area 121 (broadcast program), and adjusts the size ratio of the first area 121 and the second area 122 in the width direction. The operation menu 222 is an operation unit for selecting a channel of a broadcast program to be displayed in the first area 121. As described above with reference to FIG. 4, the channels available for the cooperation service differ depending on the distribution company. The operation menu 222 displays selectable channels available to the distribution company subscribed to the receiver 1 (user).
The operation menus 221 and 222 are pull-down type operation units, and are operated using, for example, a cursor that is moved by a remote control operation.

[Functions of Control Unit 15]
Subsequently, details of the basic function 151, the adjusting function 152, and the additional functions 153 and 154 that the control unit 15 performs according to the above-described application program will be described.

As shown in FIG. 9A, in the basic function 151, the storage unit 11 includes an available CH list 111, an initial CH list 112, and a URL list 113. Information acquired from the management server 2 (see FIG. 4) is defined in each of the available CH list 111, the initial CH list 112, and the URL list 113.
The available CH list 111 stores a channel number that can be used by a distribution company to which the user has subscribed. The channel number specified in the available CH list 111 is displayed so as to be selectable in the above-described operation menu 222 (FIG. 8). The initial CH list 112 stores an initial channel selected when the application is started. Note that the initial channel specified in the initial CH list 112 may be always selected at the time of application startup, or the initial channel may be selected only at the first startup on a weekly basis, and the second and subsequent times may be selected on a weekly basis. In this case, the channel number selected at the end of the previous application may be selected.

  As shown in FIG. 9B, the URL list 113 stores URLs of Web contents corresponding to broadcast programs (channels and time zones). In the receiver 1, only the URL of the currently selected channel may be stored as the URL list 113, and all URLs of available channels may be stored as the URL list 113 regardless of whether or not the channel is selected. It may be stored. Similarly, the receiver 1 may store the URL only in the time zone corresponding to the current time as the URL list 113, and store the URL in the predetermined time zone including the current time as the URL list 113. Is also good. Further, the receiver 1 accesses the management server 2 every time the broadcast program is switched (for example, each time the channel is switched or whenever the time zone is changed without switching the channel), and the broadcast program currently being viewed is changed. Alternatively, a URL of the Web content corresponding to one or a plurality of broadcast programs broadcasted next to the broadcast program may be acquired and stored as the URL list 113.

  Further, the URL of the Web content corresponding to the broadcast program includes the URL of each of the plurality of Web contents (main page, SNS page, column page, and program present page) corresponding to the four-color button as described above. Note that one or all of the plurality of Web contents may be a Web content common to another broadcast program. As an example, the main page may be different for each broadcast program, while the program present page may be common for each program provider (broadcasting station).

Returning to FIG. 9A, in the basic function 151, the control unit 15 functions as a first acquisition unit 161, a second acquisition unit 162, a reception unit 163, and a display control unit 164.
The first acquisition unit 161 accesses the management server 2 and acquires various information such as the URL of the Web content corresponding to the broadcast program or the channel from the management server 2. The second acquisition unit 162 includes the first acquisition unit 161. Accesses the content server 4 based on the acquired information, and acquires Web content from the content server 4.

In the basic function 151, the first acquisition unit 161 acquires an initial channel, an available channel, a channel-Web content correspondence relationship, and a business entity URL from the management server 2.
The timing at which the first acquisition unit 161 acquires the initial channel is, for example, at the time of the first activation, for example, on a monthly basis, and the timing at which the first acquisition unit 161 acquires the available channel and the business entity URL is, for example, when the application is activated. The first acquisition unit 161 accesses the management server 2 using a carrier code that identifies the distribution carrier contracted by the receiver 1 when the application is activated, and acquires these pieces of information.

  The channel-Web content correspondence is information acquired at the time of starting an application or selecting a channel, and is location information (URL) indicating the location of the Web content displayed in the second area 122. The Web content displayed in the second area 122 is different depending on the selected channel (and time zone), but the location information may be acquired for all the channels when the application is activated. Alternatively, it is also possible to acquire the selected channel at the time of channel selection. In addition, when acquiring for all channels, it is preferable to acquire information from a current time to a time after a predetermined time, and thereafter to periodically update. When displaying a broadcast program corresponding to the initial channel in the first area 121 when the application is activated, the first acquisition unit 161 acquires the location information of the Web content corresponding to the initial channel from the management server 2.

  The second acquisition unit 162 is, based on the location information acquired by the first acquisition unit 161 from the management server 2, associated with the selected channel or a broadcast program corresponding to the channel, and displayed in the second area 122. The content and the Web content displayed in the third area 123 in association with the distributor are acquired from each content server 4.

The second acquisition unit 162 acquires from the content server 4 at least the Web content associated with the selected channel among the Web contents. Note that the location information of the Web content is obtained for all channels when the application is activated or for the channel selected when the channel is selected. If the information has been obtained for all channels, the second obtaining unit 162 sets the Based on the location information associated with the selected channel among the location information for all channels, Web content corresponding to the channel is acquired.
When displaying a broadcast program corresponding to the initial channel in the first area 121 at the time of starting the application, the second acquisition unit 162 uses the location information corresponding to the initial channel and the time zone to transmit the Web content to the content server 4. To get from.

  The receiving unit 163 receives the content of an operation performed using the operation unit 13 (remote controller). As an example, the receiving unit 163 receives a selected channel indicating a channel number selected by the user of the receiver 1 from among a plurality of channels available to the distributor to which the receiver 1 has subscribed.

The display control unit 164 displays the above-described operation menu and the like in the fourth area 124, displays the broadcast program corresponding to the selected channel received by the reception unit 163 in the first area 121 of the display unit 12, and displays the second acquisition program. The Web content corresponding to the selected channel acquired by the unit 162 is displayed in the second area 122 of the display unit 12, and the Web content corresponding to the distribution company acquired by the second acquisition unit 162 is displayed in the third area 123 of the display unit 12. To be displayed.
When the initial channel is automatically selected when the application is started, the display control unit 164 displays a broadcast program corresponding to the initial channel in the first area 121, and displays Web content corresponding to the initial channel in the second area. Displayed at 122.

When the broadcast program corresponding to the selected channel cannot be displayed according to the contract content of the receiver 1, the display control unit 164 does not display the broadcast program in the first area 121, but introduces introduction information (see FIG. 4 (B)) is displayed in any of the first area 121, the second area 122, and the third area 123.
Specifically, the receiver 1 compares the selected channel with its own contract contents and determines whether the selected channel is within the contract range. At this time, if it is within the contract range, the display control unit 164 displays the broadcast program corresponding to the selected channel in the first area 121, while if it is outside the contract range, the first acquisition unit 161 Acquires the introduction information from the management server 2 (when the management server 2 holds only the URL of the introduction information, the second acquisition unit 162 acquires the information according to the URL), and the display control unit 164 acquires the introduction information. The information is displayed in the first area 121 to the third area 123. The determination as to whether or not the selected channel is within the contract range may be performed not on the receiver 1 but on the server side (the management server 2 or the distribution server 3).

[Processing of cooperation system S]
The configuration of the receiver 1 when the basic function 151 is performed has been described above. Subsequently, basic processing of the cooperation system S will be described with reference to FIG.
As shown in FIG. 10, first, in step S <b> 1, the distributor and the program supplier register various types of information in the management server 2. More specifically, the distributor registers the channels available in the cooperation system S, the initial channel, the URL of the provider, and the like in the management server 2. The correspondence with the content, the introduction information, and the like are registered in the management server 2.

  Subsequently, in step S2, when the above-described application is activated in the receiver 1, in step S3, the first acquisition unit 161 uses the provider code for identifying the delivery provider to which the first acquisition unit 161 has subscribed. , And obtains various information (available channels, initial channels, provider URLs, correspondences, etc.) associated with the distribution provider from the management server 2. The acquired various information is stored in the storage unit 11 of the receiver 1 as an available CH list 111, an initial CH list 112, a URL list 113, and the like.

  Subsequently, in step S4, the receiver 1 reads the initial channel from the storage unit 11, and then in step S5, the receiver 1 receives and decodes a broadcast signal corresponding to the channel from the distribution server 3. Subsequently, in step S6, the second acquisition unit 162 of the receiver 1 accesses the content server 4 based on the correspondence between the channel acquired in step S3 and the Web content, and acquires the Web corresponding to the selected channel. Get content. In addition, in step S6, the second acquisition unit 162 of the receiver 1 accesses the content server 4 based on the provider URL acquired in step S3, and acquires Web content corresponding to the distribution provider.

  After acquiring the broadcast program and the Web content in steps S5 and S6, subsequently, in step S7, the display control unit 164 of the receiver 1 displays the broadcast program in the first area 121, and displays the Web content corresponding to the channel. The content is displayed in the second area 122, and the Web content corresponding to the distribution company is displayed in the third area 123.

  Subsequently, in step S8, the receiver 1 determines whether or not an operation of transiting a Web page (selection of a hyperlink) has been performed in the second area 122. If this determination is YES, the process proceeds to step S6, where the second obtaining unit 162 obtains and displays the Web content of the hyperlink destination, while if this determination is NO, the receiver 1 executes the process. Move to step S9.

  In step S9, the receiver 1 determines whether the channel has been switched to another channel. When this determination is YES, receiver 1 shifts the processing to step S11. On the other hand, when this determination is NO, receiver 1 ends the processing. In step S11, the display control unit 164 of the receiver 1 determines whether or not the selected channel is a channel that can be viewed from the current contract content. If the determination is YES, the process proceeds to step S5, where receiver 1 receives and displays a broadcast program corresponding to the channel. On the other hand, when this determination is NO, the receiver 1 moves the process to Step S12.

  In step S12, the first acquisition unit 161 of the receiver 1 accesses the management server 2 and acquires introduction information for introducing the selected channel from the management server 2 (or the content server 4). Subsequently, in step S13, the display control unit 164 of the receiver 1 displays the acquired introduction information in the first area 121 to the third area 123.

[Effects Associated with Basic Function 151]
The basic function 151 of the control unit 15 has been described above. When the basic function 151 is performed, the broadcast program is displayed in the first area 121 of the display unit 12 of the receiver 1 and the Web content corresponding to the broadcast program is displayed in the second area 122. 1 can enjoy a cooperative service for coordinating broadcasting and communication. At this time, the Web content associated with the broadcast program is acquired based on the URL acquired by the first acquisition unit 161 from the management server 2. More specifically, the first obtaining unit 161 accesses the management server 2 at a predetermined timing, and obtains the URL of the Web content associated with the channel selected from the management server 2.
As described above, since the receiver 1 obtains the Web content associated with the broadcast program based on the communication with the management server 2, if the receiver 1 has a network function capable of accessing the management server 2, it can communicate with the broadcast. It is not necessary to have a dedicated function of reading an AIT from a broadcast signal.

In the basic function 151, a channel that can use the cooperative service is set in advance, and one channel can be selected from the channel. As a result, a channel in which the correspondence between the broadcast program and the Web content is not set is not selected, so that it is possible to prevent a channel in which the cooperative service can be used and a channel in which the cooperative service cannot be used.
When a special contract is required to view an available channel, the introduction information for introducing the channel is displayed. Therefore, when the user of the receiver 1 desires to view the channel, the labor required for the contract is reduced. be able to.

  In the basic function 151, an initial channel is set from available channels, and a broadcast program and Web contents corresponding to the initial channel are displayed when the application is activated. As a result, it is possible to guide the user to each program provider that provides the cooperative service, and active participation of the program provider can be expected.

  In addition, the basic function 151 displays not only a program provider (broadcasting station) that provides a broadcast program, but also Web contents corresponding to a distributor (cable TV station) that distributes a broadcast signal, together with the broadcast program. This is preferable because more diverse information can be supplied than when simply displaying Web content related to a broadcast program.

[Details of Adjustment Function 152]
Next, details of the adjustment function 152 performed by the control unit 15 according to the above-described application program will be described. FIG. 11 is a diagram illustrating an example of a display screen displayed on the display unit 12 of the receiver 1. In the second area 122, the Web content provided by the program provider is displayed. As shown in FIG. 11A, depending on the program provider, input of predetermined information in the Web content may be requested. . In the example shown in FIG. 11A, an input field 231 for inputting a name and an address for member registration is provided.

  Here, if an attempt is made to input information and the input field 231 is selected, the input window 232 may be activated at a predetermined position (for example, the center of the screen) depending on the type of the browser or the OS of the receiver 1 used. Here, since the position where the input window 232 starts is also determined by the specifications of the browser and the OS, depending on the receiver 1, as shown in FIG. 11 (B), the input window 232 has the first area 121 where the broadcast program is displayed. It starts in the overlapping position, and either one is not displayed properly. For example, if the first area 121 is set to a higher layer than the second area 122, the broadcast program is displayed in front of the input window 232, and as a result, the input window 232 is not displayed properly. If the first area 121 is set to a lower layer than the second area 122, the input window 232 is displayed in front of the broadcast program, and the broadcast program is not properly displayed.

The adjustment function 152 is preferably used in such a case as an example, and automatically activates the size of the first area 121 (broadcast program) and the second area 122 (Web content) when the input window 232 is activated. To adjust. Specifically, as shown in FIG. 11C, the adjustment function 152 adjusts the sizes of the first area 121 and the second area 122 so that the input window 232 is included in the second area 122. More specifically, the adjustment function 152 reduces the size of the first region 121 while increasing the size of the second region 122. As a result, it is possible to prevent the broadcast program and the input window 232 from overlapping.
Hereinafter, details of the configuration for exhibiting the adjustment function 152 will be described.

  FIG. 12 is a diagram illustrating a configuration when the control unit 15 performs the adjustment function 152. FIG. 12A is a functional configuration diagram of the control unit 15 and the storage unit 11, and FIG. FIG. 3 is a diagram showing an example of a size-changed content list 114 stored in a storage unit 11. Note that the adjustment function 152 is a function that is exerted in addition to the basic function 151, and the same reference numerals are given to components common to the basic function 151, and detailed description thereof will be omitted (this point is referred to as an additional function. The same applies to 153 and 154).

As shown in FIG. 12A, in the adjustment function 152, the storage unit 11 is configured to include a size-changed content list 114. As shown in FIG. 12B, the size change content list 114 defines location information (URL) indicating the location of Web content whose size needs to be changed. Note that the Web content that needs to be resized is, for example, the Web content after the above-described input window 232 is activated.
When registering the correspondence between the channel and the Web content, the program provider registers the content in the management server 2 when the Web content for starting the input window 232 is included in the Web content. The receiver 1 acquires the content from the management server 2 and manages the content as a size-changed content list 114.

  Here, when the position where the input window 232 is activated and the size of the input window 232 are variable, it is preferable that the contents of the size-changed content list 114 are also defined. The content specified in the size change content list 114 may be the position and size of the input window 232 to be activated, or the size of the Web content (the second area 122) necessary for the input window 232 to fit. It may be.

Returning to FIG. 12A, in the adjustment function 152, the control unit 15 functions as a first acquisition unit 161, a detection unit 165, an area setting unit 166, and a display control unit 164.
The first obtaining unit 161 accesses the management server 2 and obtains, from the management server 2, location information of the Web content that needs to be resized (that is, the Web content activated by the input window 232), the above-described size, and the like. I do. The timing at which the first acquisition unit 161 acquires the location information and the like is arbitrary, and may be, for example, when an application is activated or when a channel is selected. Further, the first acquisition unit 161 may acquire the above-mentioned location information and the like at the timing when the basic function 151 acquires the correspondence between the channel and the Web content.

The detection unit 165 detects a change request for changing the size of the first area 121 or the second area 122. Note that the change request is an operation request for the Web content displayed in the second area 122, and is a predetermined operation request for displaying the above-described input window 232 at a predetermined position (for example, the input field 231 in FIG. (An operation request to be selected) and an end request to end the input window 232. Of course, an operation request corresponding to an operation on the above-described operation menu 221 (see FIG. 8) is also included in the change request.
Here, the detection of the predetermined operation request is performed based on the size-changed content list 114, and when the Web content defined by the size-changed content list 114 is selected in the second area 122, the predetermined operation request is detected. . Further, the end request is detected when there is a request to transition from the Web content specified in the size change content list 114 to another Web content.

The region setting unit 166 divides the display region of the display unit 12 into first to fourth regions 121 to 124 that do not overlap with each other, and includes a first layer L1 and a second layer L2 lower than the first layer L1. The first area 121 and the fourth area 124 are set as a first layer L1, and the second area 122 and the third area 123 are set as a second layer L2.
When the detection unit 165 detects a change request, the area setting unit 166 changes the size of another area so as not to overlap the area whose size is changed in response to the change request. For example, from the state where the size in the width direction of the first area 121 and the second area 122 is in a “5: 5” relationship with respect to the entire display area, the width direction of the first area 121 is When the change request for changing the size of the second area 122 to “70%” is received for the entire display area, the area setting unit 166 sets the size of the second area 122 in the width direction to “30%” for the entire display area. Thus, the sizes of the first area 121 and the second area 122 are changed.

When the detecting unit 165 detects the above-described predetermined operation request for displaying the input window 232, the area setting unit 166 changes the size of the second area 122 so that the input window 232 is included in the second area 122, and The size of the first area 121 is changed so as not to overlap with the second area 122 whose size is changed. When the detection unit 165 detects the above-described end request, the area setting unit 166 changes the sizes of the first area 121 and the second area 122 to the sizes before the detection of the predetermined operation request.
The area setting unit 166 may change the sizes of the second area 122 and the first area 121 based on the size information specified in the size change content list 114.

  As described above, in the adjustment function 152, when the input window 232 is activated, the size of the second area 122 is expanded, and when the input window 232 is closed, the size of the second area 122 is restored. Then, the size of the first area 121 also changes in accordance with the change in the size of the second area 122.

  The display control unit 164 displays a broadcast program corresponding to the selected channel among the plurality of channels in the first area 121, and displays Web content associated with the broadcast program in the second area 122. Further, the display control unit 164 displays the Web content opened corresponding to the distributor in the third area 123, and displays the operation menus 221 and 222 of the cooperative service, the channel number currently being viewed, and the like in the fourth area 124. I do.

[Processing of cooperation system S]
The configuration of the receiver 1 when exerting the adjustment function 152 has been described above. Next, with reference to FIG. 13, a description will be given of the processing of the cooperative system S when the adjustment function 152 is performed.
As shown in FIG. 13, when the adjusting function 152 is performed, the processing of steps S21 to S23 is further included in addition to the processing of the basic function 151. Specifically, when an application is activated in the receiver 1 (step S2), the first acquisition unit 161 of the receiver 1 acquires various information from the management server 2 (step S3), and the adjustment function 152 executes step S21. As shown in (1), the first acquisition unit 161 also acquires from the management server 2 the URL of the Web content that needs to be resized at this time, and registers it in the resized content list 114 of the storage unit 11.

  Thereafter, the receiver 1 obtains the broadcast program and the Web content (steps S5 and S6). However, in the adjustment function 152, as shown in step S22, the detection unit 165 determines that the URL of the obtained Web content is It is determined whether or not the URL is registered in the size change content list 114. If this determination is YES, in step S23, the area setting unit 166 of the receiver 1 changes the size of the second area 122 so that the input window 232 is included in the second area 122, and also changes the size. The size of the first area 121 is changed so as not to overlap with the second area 122.

  The processing after changing the sizes of the first area 121 and the second area 122 in this way is the same as that of the basic function 151, and subsequently, in step S7, the first area having the size changed by the display control unit 164. The broadcast program and the Web content are displayed in the area 121 and the second area 122. In step S8, it is determined whether or not the Web content has transitioned. If the transition occurs, the process returns to step S6.

[Effects of Adjustment Function 152]
The adjustment function 152 of the control unit 15 has been described above. When the adjustment function 152 is performed, when a request for changing the size of the first area 121 or the second area 122 of the display unit 12 of the receiver 1 is made, the other second area 122 or the first area 121 is changed. The size is also adjusted automatically. Therefore, it is possible to prevent the broadcast program displayed in the first area 121 and the Web content displayed in the second area 122 from overlapping. From the viewpoint of the user, the user can surely view the broadcast program and browse the Web content, so that the convenience is not impaired. In addition, for program suppliers, their broadcast programs are displayed uninterrupted, making it easier for them to participate in cooperative services. As a result, many program suppliers become easier to participate, and service content is enhanced. Can be expected.

In particular, the adjustment function 152 adjusts the size of the second area 122 so that the input window 232 fits in the second area 122 when the input window 232 is activated in Web content displayed in the second area 122. At the same time, the size of the first area 121 is adjusted so as not to overlap the second area 122. Thereby, regardless of the specifications of the browser and OS used by the receiver 1, it is possible to prevent the input window 232 from being overlapped with a broadcast program when inputting information in Web content.
At this time, it is preferable that the URL of the Web content for starting the input window 232 be registered in advance, so that the Web content for which the size of the second area 122 needs to be adjusted can be appropriately grasped.

[Details of additional function 153]
Next, details of the additional function 153 that the control unit 15 exerts according to the above-described application program will be described. FIG. 14 is a diagram illustrating an example of a display screen displayed on the display unit 12 of the receiver 1. In the second area 122, the Web content provided by the program provider is displayed. Since the Web content is the Web content, the Web content can be freely transitioned via a hyperlink. As a result, the transition to the undesirable Web content occurs. Sometimes. Here, the undesirable Web contents include Web contents that are generally considered to be undesirable, such as phishing sites and the like, as well as Web contents that are determined to be undesirable for broadcast programs.

  For example, as shown in FIG. 14A, when a broadcast program providing special information about “Maker A” is displayed in the first area 121, competition with “Maker A” in the second area 122 is performed. It is not preferable to display the Web content for “Maker B”. Therefore, in the additional function 153, when the Web content for “Maker B” is selected in the second area 122, control is performed so that the Web content for “Maker B” is not displayed. In FIG. 14A, no web content is displayed in the second area 122 after a hyperlink transiting to web content for “maker B” is selected. For example, “cannot be displayed” Such attention information may be displayed, or control may be performed so that the transition of the Web content is not performed in the first place.

Also, a predetermined advertisement may be included in the Web content, and this advertisement may be an undesirable advertisement for a broadcast program. In the example shown in FIG. 14B, a special program about “Maker A” is displayed in the first area 121, while “Maker B” competing with “Maker A” in the second area 122 is displayed. Web content including the advertisement 241 is displayed. In such a case, the additional function 153 performs control such that the content of the Web content is displayed, but the advertisement 241 included in the Web content is not displayed.
In addition, the additional function 153 may display an advertisement for “maker A” instead of an advertisement for “maker B”. Specifically, the sponsor information (advertisement of the sponsor) is registered in association with the broadcast program, and when the broadcast program is displayed in the first area 121, the advertisement information is displayed in the advertisement space displayed in the second area 122. May display an advertisement of the registered sponsor. At this time, the registered sponsor's advertisement may be displayed only when the Web content includes an undesirable advertisement for the broadcast program, and the registered sponsor's advertisement may be displayed regardless of the advertisement in the Web content. It may be displayed.

  Thus, it is possible to prevent the undesired information for the broadcast program from being displayed in the second area 122 in the cooperation service. Hereinafter, details of the configuration for exhibiting the additional function 153 will be described.

  FIG. 15 is a diagram illustrating a configuration when the control unit 15 performs the additional function 153. FIG. 15A is a functional configuration diagram of the control unit 15 and the storage unit 11, and FIG. 3 is a diagram showing an example of a permitted / non-permitted content list 115 stored in a storage unit 11. FIG.

As shown in FIG. 15A, in the additional function 153, the storage unit 11 is configured to include a permitted / non-permitted content list 115. The permitted / non-permitted content list 115 is a so-called white list indicating a list of Web contents permitted to be displayed in the second area 122 or a so-called black list indicating a list of Web contents not permitted to be displayed. Since a broadcast program is normally distributed according to a schedule, the type of Web content that is not preferable in relation to the broadcast program differs depending on the time zone. For example, in a time zone in which a special program on the above-mentioned "Maker A" is broadcast on a certain channel, Web content about "Maker B" is not preferable, but in other time zones, "Web B" is not used. There may be no problem even if the Web content is displayed.
Therefore, the permission / non-permission content list 115 stores the location information (URL) of Web contents for which display in the second area 122 is permitted or not permitted according to the channel and the time zone. By setting the time zone finely, it is also possible to restrict the display of the Web content of a company competing with the sponsor, for example, only when the commercial of the sponsor of the broadcast program is flowing.

  Further, the Web contents include Web contents that prompt installation of an application that the receiver 1 does not support. Therefore, in the permitted / non-permitted content list 115, the Web content in which a predetermined application is installed may be defined as a Web content that is not permitted to be displayed (“URL — 299” in the example illustrated in FIG. 15B). Applies). The predetermined application may be limited to an application that the receiver 1 does not support, or may include another application other than the application.

  When registering the correspondence between the channel and the Web content, the program supplier registers a range in which transition is possible via the Web content in the management server 2 in a whitelist or blacklist format. Further, the administrator of the management server 2 registers the Web content for installing a predetermined application in the management server 2 in a blacklist format. The receiver 1 acquires the list information registered in the management server 2 from the management server 2 and manages the list information as a permitted / non-permitted content list 115.

  Returning to FIG. 15A, in the additional function 153, the control unit 15 functions as a first acquisition unit 161, a second acquisition unit 162, a determination unit 167, and a display control unit 164.

The first acquisition unit 161 accesses the management server 2 to acquire, from the management server 2, list information of Web contents permitted to be displayed together with the broadcast program or Web contents not permitted to be displayed, and the storage unit 11 Is stored as a permitted / non-permitted content list 115.
Here, the timing at which the first obtaining unit 161 obtains the list information is arbitrary, and may be, for example, at the time of application startup or at the time of channel selection. The first acquisition unit 161 acquires list information set for a plurality of channels when acquiring at the time of application startup, and acquires the list information set for a plurality of channels when acquiring at the time of channel selection. Get the set list information.

  When a channel is selected, the second acquisition unit 162 acquires Web content associated with the channel based on the URL list 113 (see FIG. 9B). In addition, when transitioning to another Web content via a hyperlink or the like, the second acquisition unit 162 acquires another transition destination Web content.

  The determination unit 167 determines whether or not to display the Web content obtained via the Web content associated with the selected channel. Specifically, the determination unit 167 refers to the permitted / restricted content list 115 and determines whether the acquired Web content is included in the list information associated with the selected channel. It is determined whether or not to display. Further, the determination unit 167 refers to the permitted / non-permitted content list 115 and determines whether to display the acquired Web content based on whether or not the acquired Web content is a Web content for installing a prohibited application. Is determined.

  As described above, the determination unit 167 may determine whether to display only the advertisement included in the Web content. Here, the determination regarding the advertisement is performed based on the URL of the link destination indicated by the hyperlink set in the advertisement. When determining whether or not to display the Web content, it is sufficient to determine whether or not the URL of the Web content itself is included in the permitted / restricted content list 115. On the other hand, when determining whether or not to display an advertisement, it is assumed that the URL of the Web content including the advertisement is not included in the permitted / restricted content list 115. Therefore, the determination unit 167 analyzes the source code of the Web content including the advertisement and determines whether the URL of the link destination of the advertisement is included in the permitted / restricted content list 115, and thereby determines the Web content. It is determined whether or not to display the advertisement included in.

  The display control unit 164 displays the broadcast program corresponding to the selected channel among the plurality of channels in the first area 121, and displays the Web content determined to be displayed by the determination unit 167 in the second area 122. In addition, when the determination unit 167 determines that the Web content is to be displayed, but determines that the advertisement included in the Web content is not to be displayed, the display control unit 164 does not display at least the advertisement in the second area 122.

[Processing of cooperation system S]
The configuration of the receiver 1 when exerting the additional function 153 has been described above. Next, with reference to FIG. 16, a description will be given of the processing of the cooperative system S when the additional function 153 is performed.
As shown in FIG. 16, when the additional function 153 is performed, the processing of steps S31 and S32 is further included in addition to the processing of the basic function 151. Specifically, when the application is activated in the receiver 1 (step S2), the first acquisition unit 161 of the receiver 1 acquires various information from the management server 2 (step S3), and the additional function 153 executes step S31. As shown in (1), the first obtaining unit 161 also obtains from the management server 2 list information for permitting / non-permitting the display together with the broadcast program at this time, and stores the permitted / non-permitted content list in the storage unit 11. Register at 115.

  Thereafter, the receiver 1 acquires the broadcast program and the Web content and displays them on the display unit 12 (Steps S5 to S7). Subsequently, in the case where the currently displayed Web content transits to another Web content (step S8), subsequently, in step S32, the determination unit 167 compares the transition destination Web content with the permitted / non-permitted content list 115. By doing so, it is determined whether or not the transition destination Web content is displayable Web content. If this determination is YES, the process moves to step S6, where the second acquisition unit 162 acquires the transition destination Web content. On the other hand, if this determination is NO, the process moves to step S9 without displaying the transition destination Web content, and performs the same processing as the basic function 151.

[Effects of Additional Function 153]
The additional function 153 of the control unit 15 has been described above. When the additional function 153 is performed, when the Web content transitions in the second area 122, it is determined whether to display the post-transition Web content, and the Web content is displayed only when it is determined to be displayed. It is displayed in the two areas 122. Thereby, it is possible to prevent Web content that is not preferable in relation to the broadcast program displayed in the first area 121 from being displayed in the second area 122. As a result, only the Web content related to the broadcast program can be displayed in the second area 122, so that the broadcast and the communication can be appropriately linked.

  As an example, by restricting the display of Web content related to a company that competes with a sponsor of a broadcast program, it is possible to protect the interests of the program provider that provides the broadcast program and to actively participate in the cooperative service. Can be expected. In addition, by restricting the display of an undesired site such as a phishing site or the like or a site where an unnecessary application is installed, it is possible to provide a cooperative service that can be used by the user with confidence, which is preferable.

  In addition, in the additional function 153, the determination unit 167 determines whether or not to display the Web content acquired by the second acquisition unit 162, but determines whether or not the second acquisition unit 162 acquires the Web content. May be determined based on the permitted / restricted content list 115. That is, Web contents that are not preferable in relation to a broadcast program may not only be not displayed on the receiver 1 but also acquired in the first place.

[Details of additional function 154]
Next, details of the additional function 154 performed by the control unit 15 according to the above-described application program will be described. In the second area 122, Web contents provided by the program supplier are displayed. In displaying Web contents, a certain period of time is usually required from when a request is made to when the Web contents are displayed. Therefore, if the display of the Web contents is delayed with respect to the broadcast programs, the broadcast programs and the Web contents are displayed. The sense of unity with is lost. Thus, the additional function 154 prevents the sense of unity from being lost by pre-reading the Web content in advance.
Hereinafter, the configuration for exhibiting the additional function 154 will be described in detail.

FIG. 17 is a functional configuration diagram of the control unit 15 and the storage unit 11 when the control unit 15 performs the additional function 154. As shown in FIG. 17, in the additional function 154, the storage unit 11 includes a history list 116.
The history list 116 stores a viewing history of a broadcast program and a browsing history of Web contents in the receiver 1. Here, the viewing history of a broadcast program is, for example, a time during which a broadcast program corresponding to the channel is viewed for each channel. Such a viewing history may be a viewing time in a situation in which a cooperative service is provided, or may be a viewing time regardless of the cooperative service. In the history list 116, it is preferable that the viewing time in the situation where the cooperative service is provided and the viewing time regardless of the cooperative service be stored in a distinguishable manner. The history list 116 stores, for each channel, the operation content for the Web content that was being viewed together with the broadcast program corresponding to the channel as a viewing history.

In addition, in the additional function 154, the control unit 15 functions as the prefetch unit 168, the determination unit 169, and the display control unit 164.
The prefetch unit 168 acquires in advance related data related to one or a plurality of Web contents corresponding to a broadcast program corresponding to one or a plurality of arbitrary channels before receiving a Web content acquisition request. Here, the related data acquired by the prefetch unit 168 may be location information (URL) indicating the location of the Web content, or may be the Web content itself. When prefetching the URL of the Web content, the prefetch unit 168 accesses the management server 2 and acquires the URL. When prefetching the Web content itself, the prefetch unit 168 accesses the content server 4 and acquires the Web content.

  In addition, the time before receiving the acquisition request of the Web content may be, for example, before a channel associated with the Web content is selected, or a hyperlink or the like for transiting to the Web content is selected. It may be before it is done.

  Also, the one or more arbitrary channels are at least one or more channels among channels available in the receiver 1, and may be only one channel among the available channels, It may be a plurality of channels or all available channels. In this regard, in the present embodiment, the determination unit 169 determines one or a plurality of channels to be prefetched from available channels.

  Specifically, the determination unit 169 determines one or a plurality of channels for acquiring related data in advance based on the viewing history stored in the history list 116. As an example, the determination unit 169 evaluates each channel based on the number of times selected and the length of viewing time (the higher the number of selected channels and the longer the viewing time, the higher the evaluation), and based on this evaluation. To determine one or more channels. Since the user's viewing tendency is considered to be related to a broadcast program instead of a channel, the determination unit 169 may perform an evaluation for each broadcast program (that is, for each time zone).

  Note that the determination unit 169 may perform predetermined weighting at the time of the above-described evaluation. The weighting may be performed based on, for example, whether or not an application is activated and / or operation information on Web content, in addition to a method of prioritizing the latest history. The weighting according to the presence or absence of the activation of the application means that, for example, a broadcast program viewed in a situation in which the cooperative service is provided is given more importance than a broadcast program viewed in spite of the cooperative service. Further, the weighting based on the operation information for the Web content means that, for example, a broadcast program in which the number of operations on the Web content displayed together is more important.

  Further, the determining unit 169 may determine, as a prefetch target related data, related data related to the broadcast program starting on the same channel after the currently viewed broadcast program. The broadcast program that starts on the same channel may be one broadcast program that starts immediately after, or a plurality of broadcast programs that start after the broadcast program currently being viewed (for example, up to three hours ahead). There may be. Further, the range to be prefetched may be determined based on the viewing history stored in the history list 116. Specifically, if the currently viewed channel is a frequently viewed channel, the prefetching range is extended (for example, a plurality of broadcast programs up to three hours ahead are prefetched), and the currently viewed channel is read. If the channel is a channel that is not often viewed, the prefetching range may be shortened (for example, only the immediately following broadcast program is set as the prefetching target).

  When receiving the selected channel indicating the channel number selected from the plurality of channels of the broadcast program, the display control unit 164 displays the broadcast program corresponding to the selected channel in the first area 121 of the display unit 12, and Is displayed in the second area 122. At this time, if related data for displaying the Web content has been acquired in advance, the display control unit 164 displays the Web content based on the related data.

The additional function 154 has been described above. Note that the target to be prefetched by the prefetching unit 168 is not limited to Web content corresponding to a broadcast program that is likely to be viewed by the user. As shown in FIG. 18, the Web content corresponding to the broadcast program includes a tab 202, and a plurality of Web contents can be switched. While displaying the Web content corresponding to one of the tabs 202, the prefetch unit 168 previously stores the relevant data of the Web content corresponding to the other tab associated with the same broadcast program as the Web content. It may be obtained.
Further, a hyperlink 251 may be set in the Web content, and it is possible to transit to another Web content via the hyperlink 251. Thus, the prefetch unit 168 may acquire in advance the relevant data of the Web content acquired via the Web content displayed in the second area 122.

[Effects of Additional Function 154]
By performing the additional function 154 described above, the look-ahead unit 168 of the receiver 1 acquires Web contents related to a broadcast program before selecting a broadcast program (selecting a channel). Thus, the receiver 1 can acquire the Web content at an early stage, so that the delay that occurs when the information is transmitted via a network can be reduced, and the broadcast and the communication can be appropriately linked.

At this time, the broadcast program (channel) for acquiring the Web content is determined in advance based on the viewing history of the user of the receiver 1, so that the Web content corresponding to the broadcast program (channel) that the user may select can be early. It can be obtained and is suitable.
Further, when a plurality of Web contents are provided in addition to the main page in association with one broadcast program, by acquiring the other Web contents in advance while displaying the main page, the other Web contents can be obtained from the main page. Even if the content is switched, the corresponding Web content can be displayed immediately.

  As described above, the present invention has been described using the embodiments, but the technical scope of the present invention is not limited to the scope described in the above embodiments. It is apparent to those skilled in the art that various changes or improvements can be made to the above embodiment. In particular, the specific embodiment of the distribution / integration of the apparatus is not limited to the above-described one, and all or a part of the apparatus is arbitrarily added according to various additions or the like, or according to a functional load. It can be configured to be distributed or integrated functionally or physically.

For example, in the above-described embodiment, the first acquisition unit 161 acquires various types of information (initial channels, correspondence, available channels, and the like) from the management server 2 when starting an application or selecting a channel. The acquisition timing is not limited to this, and the information may be acquired from the management server 2 at an arbitrary timing. The arbitrary timing is not limited to the time when the application is running, and various information may be acquired from the management server 2 even when the application is not running.
Further, the first acquisition unit 161 may acquire the respective information at the same time, or may acquire the information at different timings.
