Embodiments of the present invention will be described below with reference to the drawings.

The overall configuration of a service cooperation system including a video distribution server according to this embodiment will be described using FIG. 1. This service linkage system is a system that links broadcasting and the Web and provides related interactive services in both broadcasting and the Web. The service cooperation system shown in the figure includes a video distribution server 1 and a web server 2. The video distribution server 1 and the web server 2 are connected via a network. The sender terminal 3 and the viewer terminal 4 are connected to the video distribution server 1 via a network.

The sender terminal 3 is a terminal used by a sender to send a broadcast. The viewer terminal 4 is a terminal used by a viewer to watch broadcasts. As the sender terminal 3 and the viewer terminal 4, a personal computer or a mobile terminal such as a smartphone or a tablet can be used. Web browser 5 is connected to Web server 2 via a network. The web browser 5 is for viewing web pages provided by the web server 2, and is executed on a personal computer, mobile terminal, or the like. In this embodiment, the Web browser 5 is assumed to be a terminal used by a person who is neither the sender nor the viewer. In FIG. 1, the number of caller terminals 3, viewer terminals 4, and web browsers 5 is one each, but in reality, these numbers are much larger.

The video distribution server 1 receives broadcast video from the sender terminal 3 and distributes it to the viewer terminal 4. The broadcast video may be, for example, a live broadcast video shot with a camera connected to the caller terminal 3, or a pre-recorded video. Alternatively, it may be a still image with audio added to it. When distributing a pre-recorded video, the video distribution server 1 does not necessarily need to receive the video from the sender terminal 3, and may receive and distribute the video from a location specified by the sender terminal 3. .

When the video distribution server 1 receives an instruction to conduct a questionnaire from the sender terminal 3, it executes the questionnaire during the broadcast and also causes the web server 2 to carry out a questionnaire with the same content. Viewers can respond to the questionnaire using the viewer terminal 4. Those who are not watching the broadcast on the viewer terminal 4 can respond to a questionnaire with the same content as the questionnaire in the broadcast by accessing the Web server 2 with the Web browser 5.

The web server 2 provides a website with a questionnaire function. When the web browser 5 accesses the web server 2, it is possible to respond to a questionnaire provided by the web server 2. When the Web server 2 receives the instruction to conduct the questionnaire from the video distribution server 1, the Web server 2 executes the questionnaire. The Web server 2 transmits the results of the questionnaire conducted based on the instructions from the video distribution server 1 to the video distribution server 1. Note that the web server 2 can conduct the questionnaire independently from the broadcast, so not only viewers but an unspecified number of people can respond to the questionnaire provided by the web server 2.

Next, a configuration example of the video distribution server 1 will be described using FIG. 2. The video distribution server 1 shown in FIG. 2 includes a video distribution section 11, a questionnaire processing section 12, a command input section 13, a Web cooperation section 14, and a result reception section 15. Each section included in the video distribution server 1 may be configured by a computer including an arithmetic processing unit, a storage device, etc., and the processing of each section may be executed by a program. This program is stored in a storage device included in the video distribution server 1, and can be recorded on a recording medium such as a magnetic disk, an optical disk, or a semiconductor memory, or can be provided through a network. Each part will be explained below.

The video distribution unit 11 receives video from the sender terminal 3 and distributes it to the viewer terminal 4.

The questionnaire processing unit 12 conducts a questionnaire during the broadcast based on instructions from the caller terminal 3. Specifically, the questionnaire processing unit 12 superimposes the question text and options of the questionnaire on the video distributed by the video distribution unit 11 and displays it on the viewer terminal 4, and receives information on the options selected by the viewer. The questionnaire processing section 12 receives the results of the questionnaire during the broadcast and the questionnaire results on the Web from the result receiving section 15, and announces the questionnaire results during the broadcast. The questionnaire results may be superimposed on the video and displayed on the viewer terminal 4.

The command input unit 13 receives a command (command) input from a caller and performs processing according to the input command. Commands related to this embodiment include, for example, a command to conduct a questionnaire, a command to end a questionnaire, and a command to display questionnaire results. When the command input unit 13 receives a command to conduct a questionnaire, it controls the questionnaire processing unit 12 to carry out the questionnaire in the broadcast, and controls the web cooperation unit 14 to carry out the questionnaire on the web server 2. .

The web linkage unit 14 links broadcasts and web pages. Specifically, when a questionnaire is carried out during a broadcast, the web cooperation unit 14 transmits the question text and options of the questionnaire carried out during the broadcast to the web server 2, and sends the same questionnaire to the web server 2 as well. Have it implemented.

The result receiving unit 15 receives each of the results of the questionnaire in the broadcast and the results of the questionnaire on the Web. The result receiving unit 15 may aggregate the results of each questionnaire.

Next, with reference to FIG. 3, a process in which the video distribution server 1 conducts a questionnaire in cooperation with the Web server 2 will be described.

First, as a preliminary preparation, the video distribution server 1 causes the Web server 2 to prepare a Web page that cooperates with the broadcast based on an instruction from the sender (step S11). The video distribution server 1 generates a program ID for identifying each program, which is a unit of broadcasting. When the video distribution server 1 receives a request to link broadcasting and the web from the sender terminal 3, it transmits the program ID to the web server 2, and causes the web server 2 to prepare a web page linked to the program ID. The web page prepared by the web server 2 may be empty, or may display that the questionnaire has not yet been implemented. Alternatively, an introduction to the corresponding program may be written, or a link to a page introducing the corresponding program may be attached. Note that a user ID that identifies a sender may be used as an identifier for linking a broadcast and a web page.

The video distribution server 1 receives a URI (Uniform Resource Identifier) of a web page prepared in the web server 2. By displaying the URI on a program preview page, etc., the sender can direct people who cannot watch the program at the time it is broadcast to the Web page corresponding to the program. Further, when the Web server 2 provides an interface based on the design principle of REST (Representational State Transfer), the URI can be used to acquire, create, modify, and delete information.

The sender may link the program and the Web using the management screen provided by the video distribution server 1, or may link the program and the Web using the management screen provided by the Web server 2. good. When linking a program and the Web from the Web server 2 side, the URI of the Web page prepared by the Web server 2 and the program ID (or user ID may be used) are transmitted to the video distribution server 1.

The video distribution server 1 stores that the program and the Web are linked together, and information necessary for the linkage (for example, the URI of the Web page).

Note that the program and the Web may be linked while the program is being broadcast.

The video distribution server 1 receives an instruction to start broadcasting from the sender terminal 3 and starts broadcasting (step S12). After the broadcast starts, the video distribution server 1 receives the video from the sender terminal 3 and distributes it to the viewer terminal 4. The video distribution server 1 may receive comments from the viewer terminals 4 during broadcasting, and display the comments on the sender terminal 3 and other viewer terminals 4. A comment distribution server different from the video distribution server 1 may be used to process this comment.

When the video distribution server 1 receives the questionnaire start command from the sender terminal 3 (step S13), it starts a broadcast questionnaire (step S14). When conducting a questionnaire during broadcasting, the caller operates the caller terminal 3 and transmits the contents of the questionnaire, such as question text and options, to the video distribution server 1. The video distribution server 1 transmits the question text and options received from the caller to the viewer terminal 4, and the viewer terminal 4 uses the received question text and options to create and display a questionnaire implementation screen. The video distribution server 1 may create a questionnaire implementation screen and send it to the viewer terminal 4.

FIG. 4 shows an example of a display screen displayed on the caller terminal 3. In the video area 101 of the display screen 100, the video being broadcast and the comments input for the broadcast are displayed in a superimposed manner. The video and comments displayed in the video area 101 are the same as the video displayed on the viewer terminal 4. A comment list area 102 on the right side of the video area 101 displays a list of comments input for the broadcast. A comment input field 103 below the video area 101 is used by the sender to input a comment. When the caller inputs a comment in the comment input field 103 and presses the comment posting button 104, the input comment is posted and displayed during the broadcast.

A questionnaire area 110 at the bottom of the display screen 100 is an area for inputting questionnaire information. In the question text input field 111, a question text is input. In the option input fields 112a to 112d, options for the question text are input. When the inventor inputs the question text and options in the question text input field 111 and the option input fields 112a to 112d and presses the question button 113, the video distribution server sends the survey contents and a survey start command requesting to conduct the survey. 1. When the caller presses the result display button 114, the total results of the questionnaire are displayed.

Note that the questionnaire can also be started by inputting a command in the comment input field 103. When a predetermined character string is input in the comment input field 103 following "/", the input character string is interpreted as a command. For example, when the sender enters "/vote start question text option 1 option 2 option 3 option 4" in the comment input field 103 and presses the comment posting button 104, the question text and options 1 to 4 are displayed together with the survey start command. is sent to the video distribution server 1.

FIG. 5 shows an example of a questionnaire implementation screen displayed on the viewer terminal 4. At the top of the display screen 200, a questionnaire question 201 is displayed. Below the question text 201, option buttons 202a to 202d displaying the contents of each option are displayed. The question text 201 and the option buttons 202a to 202d may be displayed superimposed on the video to be distributed.

The viewer can respond to the questionnaire by touching any of the displayed option buttons 202a to 202d or by selecting with a pointing device such as a mouse. You may also respond to the questionnaire by entering the number assigned to the option.

Returning to FIG. 3, when broadcasting and the Web are linked, the video distribution server 1 instructs the Web server 2 to conduct a questionnaire with the same content (step S15). The video distribution server 1 transmits the question text and options received from the sender terminal 3 to the web server 2, and causes the questionnaire to be conducted on a web page linked with the broadcast.

The web server 2 rewrites the content of the web page or creates a web page using the received question text and options.

When a web page linked to broadcasting is accessed using the web browser 5, a web page 300 as shown in FIG. 6 is displayed. On the web page 300, the same question text 301 and options 302 as in the questionnaire conducted in the broadcast are displayed. In the example of FIG. 6, the viewer of the web page can respond to the questionnaire by selecting one of the options 302 using the radio buttons provided to the left of the option 302 and pressing the answer button 303.

Next, with reference to FIG. 7, the process of ending the questionnaire and displaying the results will be described.

When the video distribution server 1 receives the questionnaire end command from the sender terminal 3 (step S21), it ends the broadcast questionnaire (step S22). The caller operates the caller terminal 3 and sends a message to the video distribution server 1 to end the questionnaire. The video distribution server 1 notifies the viewer terminal 4 of the end of the questionnaire. When the viewer terminal 4 receives the notification of the completion of the questionnaire, it stops displaying the questionnaire implementation screen.

When the video distribution server 1 finishes the questionnaire in the broadcast, it also instructs the web server 2 to finish the questionnaire (step S23).

When the web server 2 receives the notification of the end of the questionnaire from the video distribution server 1, it deletes or disables the answer button 303 on the web page 300. Alternatively, the web server 2 may leave the web page 300 blank.

When the questionnaire on the web server 2 is completed, the video distribution server 1 receives the questionnaire results from the web server 2 (step S24). The questionnaire results received by the video distribution server 1 include, for example, the number of selectors or the ratio of selectors for each option. Note that the video distribution server 1 may receive the results of the questionnaire from the Web server 2 at any timing even before the questionnaire ends.

When the video distribution server 1 receives the questionnaire results from the Web server 2, it may aggregate the results of the broadcast questionnaire and the Web questionnaire.

When the video distribution server 1 receives the result display command from the sender terminal 3 (step S25), it causes the viewer terminal 4 to display the questionnaire results (step S26). The caller operates the caller terminal 3 and sends a result display command to the video distribution server 1. The video distribution server 1 transmits the results of the questionnaire to the viewer terminal 4, and the viewer terminal 4 creates and displays a questionnaire result screen that displays the results of the questionnaire.

In the questionnaire result display screen 200 of FIG. 8, a question text 201 is displayed at the top, and below the question text 201, option buttons 202a to 202d are displayed that display the content of each option and the proportion of selections. In the example of FIG. 8, the results of a broadcast questionnaire and a Web questionnaire are aggregated and displayed. The viewer terminal 4 may display only the results of the questionnaire on the broadcast or only the results of the questionnaire on the Web.

When the video distribution server 1 displays the results of the questionnaire on broadcast, it may also instruct the web server 2 to display the results of the questionnaire. The video distribution server 1 aggregates the results of the broadcast questionnaire and the Web questionnaire, and transmits the aggregated questionnaire results to the Web server 2. The web server 2 displays the received questionnaire results on a web page linked to the broadcast. The video distribution server 1 may transmit only the results of the questionnaire on broadcast, and the web server 2 may compile the results of the questionnaire on broadcast and the results of the questionnaire on the Web.

A web page 300 displaying the questionnaire results in FIG. 9 displays a question text 301 and options 302 in which the broadcast and Web questionnaire results are listed. If the viewer of the web page has responded to the questionnaire, the answer options 302 are indicated using radio buttons.

Thereafter, if the sender asks a new questionnaire during the broadcast, the new questionnaire will be implemented during the broadcast, and the Web server 2 will switch the questionnaire on the web page linked with the broadcast to the new questionnaire.

(Modified example)
Some modifications of this embodiment will be described below.

In the above embodiment, the video distribution server 1 transmits the questionnaire questions and options to the web server 2, but the video distribution server 1 may receive the survey questions and options from the web server 2.

The sender registers the question text and options for the questionnaire in the Web server 2. A plurality of questionnaires may be registered in the web server 2. The questionnaire registered on the web server 2 can be set not to be displayed on the web page until an instruction is received from the video distribution server 1.

Assume that the program has started and the video distribution server 1 has received a survey start command. If the survey start command includes an instruction to implement the survey registered in the web server 2, the video distribution server 1 instructs the web server 2 to implement the registered survey, and also The user receives the registered questionnaire questions and options from , and starts the broadcast questionnaire. If a plurality of questionnaires are registered in the Web server 2, the questionnaire to be conducted is specified in the questionnaire start command.

The web server 2 starts a questionnaire on a web page linked to the broadcast.

The web server 2 may conduct a pre-registered questionnaire before the program starts. After the program starts, the Web server 2 conducts a questionnaire according to instructions from the video distribution server 1.

The web server 2 may continue to conduct the questionnaire even after the program ends. The web server 2 stores the question text and options sent from the video distribution server 1. After the program ends, the Web server 2 continues to conduct the questionnaire using the stored questions and options according to instructions from the video distribution server 1. The results of this questionnaire can be obtained in a later program.

The sender may also use a questionnaire created by a third party. Specifically, when conducting a questionnaire during a broadcast, the caller specifies the Web page of the questionnaire to be used, and obtains the question text and options of the questionnaire. At this time, the results of the questionnaire on the web page may be obtained at the same time. The results of the questionnaire within the program may be reflected on the web page from which the information was obtained. However, in this case, permission to update the questionnaire results on the web page is required. For example, the creator of the questionnaire may set up a web page so that anyone can update the questionnaire results.

Further, a plurality of callers may share a web page linked to the broadcast. The main sender can control the web page associated with the broadcast. In other words, the questionnaire will be conducted during the broadcast and on the web at the timing of the main caller. Other callers cannot control the main caller's web page, but can obtain questions and options from the web page that cooperates with the main caller's broadcast in their own program. When the main caller conducts a questionnaire both on-air and on the web, other callers' programs receive the questionnaire's question text and options from the web server 2, and can conduct the same questionnaire in their own programs. .

When sharing a web page linked to broadcasting, any caller among a plurality of callers may be able to control the web page. In this case, a plurality of callers can take turns asking questions on the questionnaire.

Note that the answering method for the questionnaire is not limited to selecting an option, but may also be able to answer by freely inputting text, drawing a picture, or importing an image.

Furthermore, the interactive service provided in conjunction with broadcasting and the Web is not limited to questionnaires, and may be quizzes or games that can be executed on viewer terminal 4 and Web browser 5. When providing a game, the video distribution server 1 may receive the game score from the Web server 2 and tally it.

(Shopping program)
Next, an example in which the video distribution server of this embodiment is applied to a shopping program will be described.

In recent years, the buying and selling of goods between individuals via networks has become popular. Sales promotion can be expected by individuals introducing the products they sell on their own programs. In addition, prospective buyers (viewers of the program) have the advantage of being able to directly ask sellers (the sender of the program) about the product during the program.

By applying this service linkage system to shopping programs and linking the program with the web, products introduced on the program can be introduced on the website at the same time, allowing even people who cannot watch the program to access the web page. By accessing it, you can learn about the products introduced in the program.

Hereinafter, a comment function, a cart function, and an auction function will be described as examples of interactive services that link shopping programs and the Web.

First, with reference to FIGS. 10 and 11, an example will be described in which the comment function is provided on both the program and the Web, and the program and the Web are linked.

On the video of the program in FIG. 10, not only comments input by the viewer but also comments input on a web page linked to the program are superimposed. "Product number 1" at the top of the display screen 200 in FIG. 10 is information about the product currently being introduced. “Comments from the Web” at the bottom of the display screen 200 are comments entered on the Web page. Other comments are comments input by viewers.

The web page 300 in FIG. 11 includes a product image 310, a comment input field 311, a comment posting button 312, and a comment display field 313. The product image 310 is an image of a product being introduced in the program. This image may be one registered in advance on the Web server 2, or may be a screenshot of the program. When the products introduced in the shopping program change, the product images 310 also change. The timing of changing the product image 310 displayed on the web page is controlled by the program. The comment entry field 311 displays comments entered by the viewer of the web page 300. Comments input by viewers of the program may be displayed.

With reference to FIG. 12, the flow of processing in which the video distribution server 1 and the Web server 2 cooperate in a shopping program will be described.

As a preliminary preparation, the video distribution server 1 causes the web server 2 to prepare a web page that cooperates with the shopping program (step S31). The sender may register product information such as images of products scheduled to be introduced in the Web server 2.

The video distribution server 1 starts broadcasting the shopping program (step S32).

When the video distribution server 1 receives the product introduction start command from the sender terminal 3 (step S33), it determines that the product introduction has started in the program (step S34). Alternatively, the video distribution server 1 receives, from the sender terminal 3, a command to display a sub-screen, a command to display a still image, or a comment to be displayed fixedly on the screen is input. It may be determined that the product introduction is to be started. Viewers can understand the product being introduced by showing a video of the product on a sub-screen, showing a still image of the product being introduced, or displaying the product name of the product being introduced on the screen.

When the product introduction starts in the program, the video distribution server 1 instructs the Web server 2 to start the product introduction (step S35). Upon receiving the instruction, the Web server 2 displays product information on the Web page and also enables the comment function. In the example described below, the cart function and auction function are enabled.

Comments input by viewers of the program are transmitted from the viewer terminal 4 to the video distribution server 1. The video distribution server 1 superimposes the received comment on the video of the program and transmits the comment to the Web server 2. The web server 2 displays the received comment in the comment display field 313.

Furthermore, when the viewer of the web page 300 enters a comment in the comment input field 311 and presses the comment posting button 312, the web server 2 displays the input comment in the comment display field 313, and also displays the comment. Send to video distribution server 1. The video distribution server 1 superimposes the received comments on the video of the program.

In this way, comments entered on each of the programs and the web are reflected on each other. People who cannot watch the program can also comment on the products being introduced on the program. For example, you can use the comment field to inquire about products or negotiate price reductions.

When the product introduced in the program changes, the product image 310 on the web page 300 is changed. Specifically, when the video distribution server 1 receives a product change command from the sender terminal 3, it instructs the web server 2 to change the product, and the web server 2 changes the product image 310 to the image of the next product. . The video distribution server 1 introduces when it receives a command to display a sub-screen, when it receives a command to display a new still image, or when a new comment to be fixed and displayed on the screen is input. It may be determined that the product is to be changed.

Next, with reference to FIGS. 13 and 14, an example will be described in which the cart function is provided through a program and the Web, and the program and the Web are linked.

The video distribution server 1 receives orders for products from the viewer terminals 4. For example, an order for a product may be sent when a viewer enters a purchase command (for example, "/buy") in a comment input field. Alternatively, a selectable purchase button may be displayed on the display screen 200 of the viewer terminal 4, and when the viewer clicks the purchase button, the order for the product is sent from the viewer terminal 4 to the video distribution server 1. good. As in the program video shown in FIG. 13, the fact that a product has been ordered may be superimposed on the program video. The viewer can know the sales of the product from the amount of purchase comments displayed on the display screen 200.

The web page 300 in FIG. 14 includes a product image 310 and a purchase button 320. The product image 310 is an image of a product being introduced in a shopping program. A viewer of the web page 300 can order a product by pressing the purchase button 320. The Web server 2 transmits to the video distribution server 1 that a product has been ordered on the Web. When the video distribution server 1 is notified that the order has been accepted by the web server 2, the video distribution server 1 may superimpose the fact that the product has been ordered on the web onto the video of the program.

Next, with reference to FIGS. 15 and 16, an example in which the auction function is provided through a program and the Web and the program and the Web are linked will be described.

FIG. 15 is an example of a display screen of the viewer terminal 4, and FIG. 16 is an example of a web page.

The video distribution server 1 accepts bids from the viewer terminals 4. When the viewer inputs a bid command and a bid amount in the comment input field, bid information is transmitted from the viewer terminal 4 to the video distribution server 1. When the bid amount is updated, the video distribution server 1 superimposes the highest bid amount on the video of the program and transmits information on the highest bid amount to the Web server 2.

The web page 300 in FIG. 16 includes a product image 310, an amount input field 330, a bid button 331, and a bid information display field 332. The product image 310 is an image of a product to be bid on. A viewer of the web page 300 can make a bid by entering the bid amount in the amount input field 330 and pressing the bid button 331. The web server 2 transmits bid information such as the bid amount to the video distribution server 1. When the bid amount is updated by bidding from the Web, the video distribution server 1 superimposes the highest bid amount on the video of the program. Further, upon receiving information on the highest bid amount from the video distribution server 1, the Web server 2 displays it in the bid information display field 332.

Note that the web page 300 shown in FIGS. 14 and 16 may be provided with the comment function shown in FIG. 12.

As explained above, according to the present embodiment, the video distribution server 1 that receives video from the caller terminal 3 and distributes it to the viewer terminal 4 conducts a questionnaire survey during broadcasting based on instructions from the caller terminal 3. At the same time, by providing the same questionnaire to the web server 2, even those who cannot watch the broadcast when the questionnaire is conducted can respond to the questionnaire on the web provided in conjunction with the broadcast. You can participate in a survey during the broadcast. In addition, by linking broadcasting and the web, it is possible to learn the intention and background of the questioner through broadcasts related to the survey, which would not be possible just by looking at the survey questions on the web. Even people who have no intention of participating in a survey will be motivated to respond.
