(System Operation Sequence) FIG. 6 is a diagram for explaining an example of the operation sequence of the personalized moving image providing system 1 as one embodiment of the present invention. There are three columns in the sequence diagram of FIG. The left column shows the operation of the user device 6 and the browser operating on it. The middle column shows the operation of the Web server 30. The right column shows the operation of the personal information database 39. Time order (flow of time) is represented from top to bottom.

  First, a consumer (user) activates a browser on the user device 6. By specifying a predetermined address on the displayed browser screen, the member site of the Web server 30 of the business operator system 3 is accessed, the screen data returned from the Web server 30 is displayed, and the member ID is included therein. A login request is transmitted by inputting it (S01). When the request reception process 331 of the Web server 30 functions, the authentication process 332 is called immediately. In the authentication process 332, member authentication is performed by a well-known technique from authentication information input simultaneously with the member ID (S02). If the authentication is successful, the personal information acquisition process 334 functions to send a query requesting personal information to the personal information database 39 (S02). The personal information database 39 extracts data of items corresponding to the predetermined personal information from the record about the member specified by the query, and responds (S022). In the Web server 30 that acquired the personal information, the landing page generation process 335 functions to describe a tag that defines a personal information item and its value, or a script that sets a variable or array value that represents the personal information item name, and A description of a script for sending the personal information is generated at a predetermined timing, and HTML data for displaying a landing page dedicated to the member including this is created (S03).

  This member-specific landing page includes descriptions of normal screen design elements such as message texts and background images for members, as well as each member's personal information in a variable or array representing the member's personal information. Contains a script or tag description to set the value. Further, another frame for reproducing a moving image may be defined inside the landing page, and a description instructing to display a moving image container to be described later may be included therein. When the response process 339 functions, HTML data for displaying the landing page is returned to the Web browser of the user device (S04). The Web browser of the user device interprets and displays the HTML data (S05).

  The description of the operation sequence will be continued with reference to FIG. FIG. 7 is a sequence diagram for explaining an operation sequence after S05. Unlike FIG. 6, the center column represents an operation of a process that is derived from a Web browser that controls rendering of a moving image playback frame. The right column represents the operation of the personalized moving image distribution server 20.

  The browser displaying the user-specific landing page in S05 sequentially executes JavaScript (registered trademark) codes described in the HTML of the landing page. First, an event listener is set as an event handler used for subsequent inter-frame communication (S06). Here, interframe communication refers to communication between a frame of a browser base page and a moving image playback frame defined therein. In each frame, control such as display (rendering) control of screen design elements on the frame and processing control for interactive operation events on the screen is realized by independent processes. Therefore, the inter-frame communication is a form of inter-process communication when viewed from the OS of the user device.

  Next, the browser (which should be referred to as a process that controls the base page frame to be precise. Therefore, it is sometimes referred to as the base page process hereinafter) describes a tag that specifies another frame in its display window (for example, By executing “iframe tag”, a frame for reproducing a moving image is created inside the landing page (S07). As a result, a process for controlling the moving image reproduction frame (hereinafter referred to as a moving image reproduction frame process) is newly generated. The generated moving image playback frame first requests a moving image container to the personalized moving image distribution server 20 (S08). For example, when creating a video playback frame using an iframe tag, the acquisition address (URL) of a resource displayed in a newly generated frame can be specified by specifying the src attribute of the iframe tag described above. However, it is possible to specify a predetermined path of the personalized moving image distribution server 20 as the acquisition destination address.

  The personalized video distribution server 20 that has received the video container request assembles HTML data to be provided as a video playback container by operating the resource (execution type program for executing the container generation process 233) indicated by the designated path. (S09). Then, the created HTML data is sent to the video playback frame process as a response to the video container request (S10).

  FIG. 8 is a diagram for schematically explaining one example of HTML data created in S09 (the matter described in FIG. 8 is an example for ease of explanation). In FIG. 8, an area of a variable array personaldata [0],..., Personaldata [19] having a length of 20 is secured between <script> and </ script> at the beginning. This is a description part of variables and arrays for accommodating personal information of users to be acquired later. Also, for displaying video playback elements (video) such as <video id = ...> and <canvas id = ...>, and any character / graphic elements on the video playback frame, overlaid on the playback video. There is a description part that defines a display element displayed on the Web browser screen, such as a graphic element (canvas) that defines a layer. Further, <script src = XXXX.player.js...> Is a description part of a program code (moving image synthesis reproduction code) for drawing a moving image according to a predetermined moving image scenario. The personalized video according to the present embodiment is a still image element or text element placed on a layer of a canvas element defined by <canvas id = ...> on a video playback element defined by <video id = ...>. Is displayed as an animated image reflecting personal information.

  Actually, what kind of video data is adopted for each content to be distributed, in what order to play it, at what timing text information and still images reflecting personal information are drawn, or individual Depending on the value of information, which video is to be selected and reproduced next is determined in advance as a scenario along the time axis, and such a scenario is executed on a Web browser. Realized as a program. The above src = XXXX.player.js is a description for calling the source code of the program.

  The description part of the variable / array that contains the personal information, the description part that defines the browser display element, and the description part of the program code that draws the video are fixed according to the theme of the personalized video and prepared in advance. Just read a text file. The container generation process 233 creates an HTML file, which is a text file prepared in advance, for each personalized moving image theme (ie, moving image content).

  Returning to FIG. When the video playback frame process receives a video container from the personalized video distribution server 20 (S10), an event listener as an event handler for communicating with the base page process is set later (S11, setting an event listener). A script and a script for performing notification described later are also described in the moving image playback container in step S09). Then, the base page process is notified that the acquisition of the moving image playback container is completed (S12). This notification can be realized, for example, by using a JavaScript (registered trademark) postMessage () method.

  This notification is detected by the base page process by the action of the event listener set by the base page process in S06, and the base page process is a process preset in the event handler in S06, that is, an individual embedded in the base page. A process of sending information (data incorporated in S03) to the moving image playback frame process is executed (S13). This processing can also be realized by specifying a variable or array storing personal information as an argument as an argument with a JavaScript (registered trademark) postMessage () method as in S12.

  On the other hand, the moving image playback frame process detects this data transmission by the action of the event listener set in S11. In S11, the process set as the event handler is performed. For example, in the case of the HTML illustrated in FIG. 8, the transfer data is copied to the array personaldata, and the sent personal data is acquired. (S13).

  When the acquisition of personal data is complete, the video playback frame process interprets and executes or renders the remaining description of the HTML data of the video playback container. A basic moving image data file and other material data are obtained from the content distribution server 40 (S14, at this time, a source file in which the moving image synthesizing / reproducing code is described may be obtained). Finally, the moving image synthesis playback code is interpreted and executed. Then, the personalized moving image using the acquired moving image data and material data is rendered and displayed on the user device (S15).

  FIG. 9 is a diagram schematically illustrating an example of a moving image synthesis / playback code. The matter shown here is an example for easy explanation. When the HTML file in FIG. 8 is read and interpreted by the Web browser, XXXX.players.js written in JavaScript (registered trademark) is finally read, and the code shown in FIG. 9 is executed on the user device. Interpretation is performed. These codes refer to the value of the array personaldata in which the personal data is set in step S13 in FIG. 7, set the video data used in the video reflecting the personal information and the order thereof, and “videoTag.play (); ”Executes an instruction to play the moving image file currently set in the src attribute. In other words, the moving images to be reproduced and their order are set according to the personal information.

  The if statement block below is an example in which the display text corresponding to the value of personaldata [2] is selected and reproduced. In this way, it is possible to switch the text to be displayed on the moving image by conditional branching according to the value of an item in the personal information. Similarly, by using the if statement block and setting the video file specified in VideoTag.src by conditional branching according to the value of an item with personal information, the video to be played next can be switched and played. You can also control the screen. In this way, a personalized video relating only to the user is provided.

(Second Embodiment) Next, a personalized moving image providing system 1B as a second embodiment will be described. In the second embodiment, the client device does not request the personalized video distribution server 20 for a video playback container, and the client device itself generates the video playback container. In the following, the second embodiment will be described. However, the same reference numerals are given to the components that are the same as those in the first embodiment, and the description thereof will be omitted. The description will focus on the parts that are different from the first embodiment. To do.

  (Outline of Personalized Video Providing Method) FIG. 10 is a schematic diagram showing an outline of the second embodiment of the personalized video providing method (personalized video distribution and playback method) according to the present invention. First, a user logs in to a company website (Web server 30 of the company system 3) from a Web browser activated on the user device. When the user authentication is successful, the business operator system 3 returns the first HTML data as the landing page of the user in which the personal information of the user is embedded as a response to the login request ((1) in FIG. 10).

  In the first HTML data, not only the personal information of the user (predetermined personal information items and their values, for example, name, recent purchased product, current insurance contract contents, etc.) is described and embedded. A description of a code for generating another frame for reproducing a moving image is included. Therefore, when the Web browser receives the first HTML data, it interprets this to create and temporarily store an HTML file to be used later as a video playback container, and generate another frame on the browser screen. A script for incorporating a moving image reproduction container (a temporarily stored HTML file) is executed ((2) in FIG. 10). By executing this code (exemplified as newframe.js in FIG. 10), HTML that functions as a video playback container when it is later incorporated into another browser frame without making a request to the personalized video distribution server 20 Data (second HTML data) is provided to the Web browser of the user device. As a result, the video playback container is displayed in the frame newly defined on the user landing page of the Web browser of the user device ((3) in FIG. 10, the browser screen in this state is indicated by 60c). ).

  A Web browser (more precisely, a process derived from the Web browser for controlling display of a newly generated frame) starts interpreting and executing a program code (personal information acquisition script) for acquiring the personal information. The derived process acquires the personal information data embedded in the first HTML ((4) in FIG. 10), synthesizes and reproduces a moving image reflecting the personal information in accordance with predetermined template information ( (7) in FIG. 10, the browser screen in this state is represented by 60d)). When synthesizing a personalized video, material data such as still images and audio files used for video synthesis is accessed by the content distribution server 40 and acquired as needed depending on the content of the video content ((5) in FIG. 10). (6)).

  FIG. 11 is a diagram illustrating the overall configuration of a personalized video providing system 1B that implements the second embodiment of the present invention that provides a user with a personalized video according to the outline processing procedure described in FIG. The personalized video providing system 1B is configured by connecting a business system 3, a content distribution server 40, and a user device 6 via a network 5. The personalized video distribution server 20 that is one element constituting the personalized video providing system 1 is unnecessary.

  The business operator system 3 includes a Web server 30 and a personal information database 39. The Web server 30 and the personal information database 39 are different from those in the personalized video providing system 1 except that the contents of the HTML (first HTML) for displaying the user landing page provided by the Web server 30 are partially different. Absent. The positioning of the content distribution server 40 is not different from that in the personalized video providing system 1. That is, in practice, the Web server 30 may also serve as the functional role of the content distribution server 40, although this is not considered in practice.

(Operation sequence)
FIG. 12 is a sequence diagram for explaining the operation sequence of the second embodiment. The operation of the personalized video providing system 1B will be described with reference to FIG. In the personalized video providing system 1B, after the consumer (user) activates the browser on the user device 6, the first HTML, which is a landing page dedicated to the member, is displayed on the Web browser of the user device. Is the same as that of the personalized video providing system 1 (from S01 to S05 in FIG. 6). The subsequent operation sequence will be described with reference to FIG.

  The browser displaying the user-specific landing page in S05 sequentially executes JavaScript (registered trademark) codes described in the HTML of the landing page. First, an event listener is set as an event handler used for subsequent inter-frame communication (S06). Next, Javascript code for generating a moving image playback frame is executed (S100). FIG. 10 shows an example with the name newframe.js. The Web browser generates an HTML file that functions as a moving image playback container by sequentially executing the scripts described in this file. This HTML file is temporarily stored in the storage area of the user device as a file with an appropriate (but fixed) name. Next, in newframe.js, a new frame is defined in the landing page of the user, and an HTML file that functions as a moving image playback container that has been played back earlier is incorporated therein (S104). This is the same as the state in which the video container has been received from the personalized video distribution server 20 in S10 of FIG. 7 in the first embodiment. Since the subsequent operation sequence is the same as S11 to S15 in FIG. 7, the description thereof is omitted.

  As described above, in the personalized video providing system 1B, the HTML file used as the video playback container is prepared locally on the user device, so the personalized video distribution server 20 is not necessary.
