  The length 10f indicates the vertical and horizontal lengths of the Web screen defined by the WHC.

  FIG. 11 is an explanatory diagram for explaining the base coordinates 10e and the narrowness 10f.

  In FIG. 11, base coordinates (Xb, Yb) 10e indicate the coordinates of the upper left corner of the Web screen 11a defined by the WHC, and Xs of long and narrow 10f indicates the horizontal length of the Web screen 11a. The Ys of the narrow 10f indicates the vertical length of the Web screen 11a.

  Returning to FIG. 4, the Web screen creation unit 42h1 outputs the created WHC to the display control unit 42h8. The display control unit 42h8 is realized by an OS, for example.

  Further, the Web screen creation unit 42h1 provides the WCDG 42h2 with content described in HTML and APL identification information indicating the APL for displaying the content.

  The WCDG 42h2 is an example of a detection unit, and detects the type of content provided from the Web screen creation unit 42h1 and APL identification information.

  Here, content type detection will be described.

  For example, the WCDG 42h2 first obtains an HTML display content pointer provided from the Web screen creation unit 42h1.

  Subsequently, the WCDG 42h2 detects a notation indicating the type of the HTML document (for example, “Text” indicating the content of the text, “MARQUEE” indicating the content of the telop format) from the obtained display content pointer.

  If the content is a moving image, the WCDG 42h2 detects a notation plugged in the HTML language. For example, the WCDG 42 h 2 detects a Flash (indicating an animation) or a movie (indicating a moving image) indicating an attribute of a source to be displayed following the EMBED function.

  The WCDG 42h2 provides the detected APL identification information and the detected notation to the content evaluation value determination unit 42h3.

  When the content evaluation value determination unit 42h3 receives the APL identification information and the notation, the content evaluation value determination unit 42h3 reads the assigned score associated with the accepted notation from the CETBL 42c1. The content evaluation value determination unit 42h3 associates the read awarded score with the accepted APL identification information and stores the associated score in the CEVD 42c2.

  The WHCG 42h4 is an example of a Web screen information detection unit.

  The WHCG 42h4 obtains the WHC output from the Web screen creation unit 42h1. The WHCG 42h4 provides the acquired WHC to the display time measurement unit 42h5 and the Web screen evaluation value determination unit 42h6.

  The display time measuring unit 42h5 measures the display time of the Web screen based on the provided WHC. The display time measuring unit 42h5 provides the measured Web screen display time to the WEAP 42h7.

  For example, the display time measuring unit 42h5 measures the time until the WHC command name 10a issued from a certain APL changes from Open to Close, and the measured time is displayed on the Web screen displayed on the APL. The display time is provided to WEAP42h7.

  The Web screen evaluation value determination unit 42h6 determines the evaluation value of the Web screen based on the WHC (the size and display position of the Web screen) provided from the WHCG 42h4.

  For example, the Web screen evaluation value determination unit 42h6 reads the base coordinates 10e from the provided WHC.

  Subsequently, the Web screen evaluation value determination unit 42h6 selects an area including the read base coordinates 10e from the PETBL 42c3.

  Subsequently, the Web screen evaluation value determination unit 42h6 reads the position evaluation value associated with the selected area from the PETBL 42c3.

  The Web screen evaluation value determination unit 42h6 reads the narrow 10f from the provided WHC.

  Subsequently, the web screen evaluation value determination unit 42h6 calculates the area of the web screen based on the read narrowness (Xs, Ys) 10f. For example, the Web screen evaluation value determination unit 42h6 calculates Xs × Ys to calculate the area of the Web screen.

  Subsequently, the Web screen evaluation value determination unit 42h6 detects the ratio of the area of the Web screen to the area of the display screen 4a acquired in advance. The Web screen evaluation value determination unit 42h6 calculates the ratio of the number of dots included in the Web screen to the number of dots included in the display screen 4a acquired in advance, and the area of the display screen 4a acquired in advance. The ratio of the area of the web screen to the screen may be detected.

  The Web screen evaluation value determination unit 42h6 determines the evaluation value of the Web screen based on the calculated ratio and the read position evaluation value.

  For example, the Web screen evaluation value determination unit 42h6 multiplies the area ratio and the position evaluation value for each APL, and uses the result as the evaluation value of the Web screen of that APL.

  The Web screen evaluation value determination unit 42h6 associates the APL identification information and the evaluation value of the APL Web screen specified by the APL identification information with each other and stores them in the PEVD 42c4.

  The WEAP 42h7 recognizes the viewer for the content based on the assigned points stored in the CEVD 42c2, the evaluation value of the Web screen stored in the PEVD 42c4, and the display time of the Web screen provided from the display time measurement unit 42h5. Calculate the degree.

  For example, the WEAP 42h7 calculates, for each APL, the number of awarded points × the evaluation value of the Web screen × the display time of the Web screen. The WEAP 42h7 stores the calculation result (viewer's recognition degree of the content) in the WDTED 42c5 for each APL.

  When receiving the WHC, the display control unit 42h8 analyzes the received WHC and provides the analysis result to the graphic circuit 42i.

  The transmission control unit 42h9 periodically reads the recognition level stored in the WDTED 42c5 and transmits the read recognition level to the service server 3.

  FIG. 20 is a flowchart for explaining a Web screen evaluation value determination operation when a plurality of Web screens are displayed in an overlapping manner. In FIG. 20, the same processes as those shown in FIG. 17 are denoted by the same reference numerals.

  Hereinafter, a Web screen evaluation value determination operation when a plurality of Web screens are displayed in an overlapping manner will be described with reference to FIGS. 19 and 20. Note that, in order to avoid duplication of explanation, the explanation will focus on the differences from the operation shown in FIG.

  In the following, it is assumed that after APL # 1 issues a WHC, APL # 2 issues a WHC having an upper display request (overlapping state: UP + 1).

  When the display control unit 42h8 realized by the OS receives the WHC issued by APL # 2, the display control unit 42h8 executes Step 2001.

  In step 2001, the display control unit 42h8 analyzes the received WHC and displays an analysis result indicating that the display plane of the APL # 2 Web screen is higher than the display plane of the APL # 1 Web screen as a graphic circuit. 42i and activates, that is, displays the APL # 2 Web screen.

  When APL # 2 issues a WHC, the WHCG 42h4 executes Step 2002.

  In step 2002, the WHCG 42h4 obtains the WHC issued by APL # 2. The WHCG 42h4 provides the acquired WHC to the display time measurement unit 42h5 and the Web screen evaluation value determination unit 42h6.

  When the Web screen evaluation value determination unit 42h6 receives the WHC, it executes Step 2003.

  In step 2003, the Web screen evaluation value determination unit 42h6 displays the overlap state 10b, the base coordinates 10e, and the narrow 10f indicated in the accepted WHC and the WHC issued from the APL # 1 that has already been accepted. Based on the base coordinates 10e and the narrow 10f, the area of the overlapping portion between the APL # 1 Web screen and the APL # 2 Web screen is calculated.

  When the Web screen evaluation value determination unit 42h6 calculates the area of the overlapped portion, it executes Step 2004.

  In step 2004, the Web screen evaluation value determination unit 42h6 first calculates the area of the Web screen of APL # 1 based on the narrow 10f indicated in the WHC issued from APL # 1. Thereafter, the Web screen evaluation value determination unit 42h6 calculates the area of the Web screen of APL # 1 that is actually displayed by subtracting the area of the overlapping portion from the area of the Web screen of APL # 1.

  When the area of the Web screen of APL # 1 that is actually displayed is calculated, the Web screen evaluation value determination unit 42h6 executes Step 1707.

  FIG. 21 is an explanatory diagram for explaining the recognition degree calculating operation. In FIG. 21, the same components as those shown in FIG. 4 are denoted by the same reference numerals.

  The recognition level calculation operation is executed periodically, for example.

  In the recognition degree calculation operation, the main CPU 42h executes WEAP, displays the assigned points stored in the CEVD 42c2, the evaluation value of the Web screen stored in the PEVD 42c4, and the display of the Web screen provided from the display time measuring unit 42h5. Based on the time, the viewer's recognition level for the content is calculated.

  For each APL, the main CPU 42h stores the calculation result (recognition level of the viewer for the content) in the WDTED 42c5.

  When the main CPU 42h (transmission control unit 42h9) receives a recognition degree request for requesting a recognition degree every predetermined time (for example, one day or one week) or from an external server, the recognition degree stored in the WDTED 42c5 Is sent to the designated server via the LAN circuit 42a.

  The degree of recognition sent to the server can be applied in various ways.

  FIG. 22 is an explanatory diagram showing a form in which the service provider that manages this service manages and operates the service server 3. In FIG. 22, the same components as those shown in FIG.

  In this service, there are a plurality of businesses that develop business using BB's Web based on some related information related to the contents of TV programs. In FIG. 22, these operators are shown as WebD operators from WebA operators.

  These businesses accept viewers' recognition of the content displayed on their Web screen from the general business operator (service server 3). The service server 3 may distribute the degree of recognition to each business operator.

  Next, a description will be given of a business performed by these four operators using this system.

1) Business type of WebA operator This type is a business type performed by an advertising operator, and performs TV cooperation by exchanging information with a TV station to some extent.

  FIG. 23 is an explanatory diagram for explaining this type. In FIG. 23, the same components as those shown in FIG. 22 are denoted by the same reference numerals.

  In FIG. 23, the WebA provider obtains information related to the contents of the TV program in advance from the TV station. This content is more substantial than the publicly announced electronic program guide (EPG). The WebA provider obtains information on all items to be sold such as clothes, furniture, and ingredients used in the TV program, displays related products and contents for selling information on the Web screen, We conduct business to sell them online.

  In addition, the WebA provider receives an advertising fee from the advertiser and places an advertisement desired by the advertiser on the content.

  The WebA provider uses the viewer's degree of recognition of the content as a calculation standard for the advertisement fee.

  In addition, the WebA operator may return the incentive to the viewer in order to increase the viewer's recognition of the content.

2) Business type of WebB operator In this type, the TV station conducts a Web business centering on itself or a business entity in a group of TV stations.

  FIG. 24 is an explanatory diagram for explaining this type. 24, the same components as those shown in FIG. 22 are denoted by the same reference numerals.

  In FIG. 24, the TV station has detailed information about its own TV program in advance, and can provide advantageous contents on the Web in accordance with the timing of the TV program broadcast. Therefore, it seems that the popularity of the Web will increase. On the other hand, a TV station may have a limited business scope, and most of the products sold are limited to program-related goods, program videos, books, and the like. If it does not compete with the sponsor of the TV program, it is possible to carry out an advertisement.

  In this case, the TV station measures how the viewer's Web is viewed and what interest the viewer is interested in by viewing the content of the viewer for the content in units of TV programs. Is possible.

  Further, when the TV station itself implements a service through cooperation between broadcasting and communication, the viewer's recognition degree for the content is effective as a means for monitoring the viewing state of the cooperation, and is useful for improving the quality of the TV program.

3) Business type of WebC operator This type carries out independent business that is not directly related to TV stations.

  FIG. 25 is an explanatory diagram for explaining this type. In FIG. 25, the same components as those shown in FIG. 22 are denoted by the same reference numerals.

  In FIG. 25, the WebC provider analyzes generally available program information (EPG, etc.), or the contents of a program that has already been broadcast, and provides information according to the program contents or information about goods. Do business that sells or advertises.

  Even for a program that has already been broadcast, since the viewer can be fully aware of the previous drama of the series, the previous one may be displayed on the web in accordance with the current drama.

  In this type, the viewer's awareness of the content is particularly important. Since the WebC business operator does not obtain the detailed information directly from the TV station, the degree of recognition can be indispensable information for grasping the needs of the viewer.

4) Business type of WebD operator This type can be constructed by, for example, a major mail order company.

  FIG. 26 is an explanatory diagram for explaining this type. In FIG. 26, the same components as those shown in FIG. 22 are denoted by the same reference numerals.

  In FIG. 26, the WebD provider can establish a joint venture with a program information magazine company, a TV station, etc., obtain abundant program advance information, generate related information, and prepare items for sale in advance.

  In this system, incentives such as gathering members widely, building a customer DB (database), accumulating the degree of recognition of individual members, and applying the accumulated points of confirmation to discounts on sales of goods are possible.

  As shown in the example of each business, even in various patterns, by using the viewer's recognition level for the contents linked with the TV program, the cooperation service of TV broadcasting and BB can be utilized and applied to business evaluation. Is possible.

  In this service, it is possible to evaluate the matching between the TV program being displayed and the content by using the degree of viewer recognition of the content.

  The content displayed on the Web screen linked with the TV program can be displayed even if the TV program is not displayed.

  Further, as shown in FIG. 27, the content displayed on the Web screen linked with the TV program may be displayed on a display screen different from the display screen displaying the TV program.

  Specifically, the TV screen is displayed only on a TV different from the display device 4, and the Web screen is displayed only on the display device (for example, PC) 4. In this case, a TV having a LAN interface, such as a digital TV, is connected to the PC (display device 4) via a LAN, and the cooperation between the TV program and the Web screen is realized.

  In addition, an indicator “display rate” indicating the relationship between the time when the Web is displayed and the display time of the TV program linked with the Web may be introduced.

  This “display rate” indicates the state of the TV video when the Web is posted. For example, if a Web screen linked to a TV program has been displayed for 4 hours, it is clear how many hours of that TV program was being broadcast, where was the channel, or where the recorded TV program was being watched It becomes possible to.

  According to the present embodiment, the following effects can be obtained.

  When the content of video streams and video files with a higher impression level is widely used in web advertisements due to the spread of broadband, and the viewers watch these video contents as advertisements displayed on the web screen, the degree of viewing That is, it is possible to measure the size of the display window on the Web screen, the position on the screen, and the viewing time, and evaluate the recognition degree of the corresponding content such as an advertisement.

  Further, in the service of cooperation / fusion of broadcasting and communication, it is possible to measure the degree of content recognition even if the TV program and the content can be displayed independently.

  It is also possible to grasp the development status of content on a PC or TV screen.

  In addition, an index that is an effective display rate can be introduced.

  Note that the content provided from the service server 3 may indicate a URL of predetermined related content, and when the URL is clicked, a Web screen indicating the predetermined related content may be displayed. In this case, the recognition level of the user may be calculated for the newly displayed Web screen.

  According to the present embodiment, when the WCDG 42h2 detects a content type, the evaluation unit 42B calculates a viewer's recognition level for the content based on the detected content type.

  There is a high possibility that the user's degree of recognition of the content will change depending on the type of content. For example, in many cases, a moving image content has a higher recognition level than a still image content.

  For this reason, it becomes possible to calculate the recognition degree of the user with respect to the content according to the type of the content. Therefore, it becomes possible to calculate a user's recognition degree with respect to the content displayed in conjunction with the television program with high accuracy.

  In this embodiment, the evaluation unit 42B reads the content evaluation value associated with the detected content type from the CETBL 42c1, and calculates the recognition level based on the content evaluation value.

  In this case, the type of content and the content evaluation value that is the evaluation value of the content of that type can be managed in CETBL 42c1.

  In this embodiment, the content is displayed on a Web screen linked with a TV program, the WHCG 42h4 detects the size and display position of the Web screen, and the Web screen evaluation value determination unit 42h6 detects the detected Web. The Web screen evaluation value is calculated based on the screen size and the display position, and the WEAP 42h7 calculates the recognition degree based on the Web screen evaluation value and the content evaluation value.

  The more the content is displayed on a large Web screen, the greater the possibility that the user's recognition level for the content will be higher, and the more the Web screen display position is more conspicuous, the higher the user's recognition level for the content. Is likely to be higher.

  For this reason, it becomes possible to calculate the recognition degree of the user with respect to the stream type content with high accuracy.

  In this embodiment, the Web screen evaluation value determination unit 42h6 detects the ratio of the size of the Web screen to the size of the display screen that displays the Web screen, and the detected ratio and the display position of the Web screen The Web screen evaluation value is calculated based on the above.

  The higher the ratio of the size of the Web screen to the size of the display screen, the greater the possibility that the user will recognize the content.

  For this reason, it becomes possible to calculate the recognition degree of the user with respect to the content with higher accuracy.

  In this embodiment, the Web screen evaluation value determination unit 42h6 converts the detected display position of the Web screen into a position evaluation value associated with the display position, and the size and position evaluation value of the Web screen. Based on the above, the Web screen evaluation value is calculated.

  For example, when an evaluation value is set according to the conspicuousness of the display position, the evaluation value indicates the conspicuousness of the content.

  For this reason, it becomes possible to calculate the recognition degree of the user with respect to the content with higher accuracy.

  In this embodiment, the Web screen evaluation value determination unit 42h6 detects the ratio of the size of the Web screen to the size of the display screen that displays the Web screen, and based on the detected ratio and the position evaluation value. The Web screen evaluation value is calculated.

  In this case, it becomes possible to calculate the degree of user recognition of the content with higher accuracy.

  In this embodiment, the Web screen evaluation value determination unit 42h6 detects the size of the Web screen that is actually displayed.

  In this case, for example, even if another Web screen is overlaid and the Web screen that is actually displayed becomes smaller, the user's degree of recognition of the content is calculated based on the size of the reduced screen. It becomes possible to do. For this reason, it becomes possible to calculate the recognition degree of the user with respect to the content with higher accuracy.

  In the present embodiment, the display time measurement unit 42h5 measures the display time of the Web screen, and the WEAP 42h7 further calculates the recognition degree based on the measured display time of the Web screen.

  The longer the display time of the Web screen, the greater the possibility that the user will recognize the content.

  For this reason, it becomes possible to calculate the recognition degree of the user with respect to the content with higher accuracy.

In addition, the transmission control unit 42h9 desirably transmits the calculated recognition level to a management device (for example, the service server 3) that manages the recognition level of the user with respect to the content. In this case, the management device (for example, the service server) In 3), it becomes possible to automatically collect the degree of recognition of the user with respect to the content.

  In the embodiment described above, the illustrated configuration is merely an example, and the present invention is not limited to the configuration.

  For example, the content is displayed on a Web screen that is linked to a TV program and displayed on the same display screen as the TV program, and the main CPU 42h specifies that the Web screen is operated after the display of the TV program is stopped. The operation may be detected, and the degree of recognition may be further calculated based on the detection result of the specific operation.

  When a specific operation is executed, there is a high possibility that the user's interest has shifted from the television program to the content. For this reason, in this case, it becomes possible to calculate the degree of user recognition of the content with higher accuracy.
