  FIG. 4 is a diagram for explaining the flow of processing for registering moving image content and annotations of the moving image content in the moving image management server 1 of the present invention. In FIG. 4, after the thumbnail image is generated from the moving image content, the moving image content, the thumbnail image, and the annotation are registered in the database 10 of the moving image management server 1, and a moving image that matches the condition by searching or the like. Image server candidates such as thumbnails are distributed or displayed by the Web server 30. In step S101 of FIG. 4, the client connected to the moving image management server 1 generates a thumbnail image from the moving image content. For example, the thumbnail image is generated for each scene in the moving image content, and is associated with the time of each scene. The scene time is, for example, the time stamp of the first image of the scene, the time stamp of the last image, or the time stamp of the image extracted as a thumbnail image. Note that the processing in step S101 may be executed by the moving image management server 1.

  In step S102, the moving image content and the thumbnail image are uploaded to the moving image management server 1 together with information for associating them with each other, and then registered in the moving image management database 23 of the moving image management server 1.

  In step S103, moving image content is distributed by the moving image management server 1. More specifically, the HTML data generation unit 12 generates HTML data including the thumbnail image of the moving image content and the URL of the moving image content, and the Web server 30 transmits the HTML data to the client. The viewer selects the URL of the moving image content included in the HTML data by clicking the URL of the moving image content included in the HTML data from the Web browser or the like of the client, and the moving image management server 1 uses the Web server 30 to select the selected moving image content. Send to.

  In step S104, a viewer who browses the moving image content on the client inputs the annotation from the input unit, thereby giving the annotation to the moving image content. In step S104a, an impression annotation is given, in step S104b a text annotation, in step S104c an annotation to a rectangular range, and in step S104d other annotations are given. The annotation given in steps S104a to S104c is an annotation given by the Web server function of the moving image management server.

  The impression annotation is an annotation that is acquired when a viewer presses a predetermined button during reproduction of moving image content. The predetermined button is, for example, a GUI button generated on the Web browser, and displays the impression content for the viewer by using icons such as “Nice” and “Booo”. The impression annotation may be acquired by converting the degree of impression into a numerical value based on the number of times the viewer presses the button. Thereby, the degree can be statistically managed for each content of the impression.

  The text annotation is an annotation that is acquired when a viewer inputs characters from input means such as a keyboard during reproduction of moving image content. The text annotation may be composed of words or short sentences. Thereby, a more detailed annotation than the impression annotation can be given.

  The annotation to the rectangular range is an annotation given to a predetermined rectangular range selected by the viewer within the playback angle of view of the moving image content. A viewer selects a rectangular range with a mouse pointer and inputs an annotation to the rectangular range by inputting a word or a short sentence from a keyboard or the like.

  Other annotations are other annotations of steps S104a to S104c. Other annotations may be annotations expressed by images, sounds, or the like in addition to characters.

  In step S105, the annotation registration unit 11 acquires the annotation given in step S104 from the client by the Web server 30, and gives the user identification information of the given viewer and the reproduction range information to which the annotation is given. And stored in the moving image management database 23. The reproduction range information is, for example, a time stamp of the start point or end point of the portion corresponding to the annotation in the moving image content. The information on the reproduction range may be information on the rectangular range selected by the viewer in the case of annotation to the rectangular range.

  In step S106, the annotation retrieval unit 13 retrieves the annotation stored in the moving image management database 23 based on the keyword or the like input from the client by the viewer, the annotation that matches the condition, and the annotation The URL and playback range of the content corresponding to is extracted. The HTML data generation unit 12 generates HTML data including an enlarged URL and a thumbnail image from the extracted information, and causes the Web server 30 to display it on the client.

  FIG. 5 is an example of a thumbnail image displayed on a display device controlled by the client. In FIG. 5, comment A is assigned to the three scenes corresponding to the thumbnail images a to c, comment B is assigned to the two scenes corresponding to the thumbnail images de to e, and the thumbnail images f to h are added. A comment C is given to the corresponding three scenes. The thumbnail image also serves as a link to the scene of the moving image content corresponding to the thumbnail image.

  An example of HTML data for performing the display shown in FIG. 5 is shown in FIG. The description indicated by 6a in FIG. 6 is a description of the enlarged URL including the content URL of the moving image content. “Http: // server / content / content ID” is acquired as the content URL from the expanded URL “http: // server / content / content ID / content ID / start time s− / user identification information” described in 6a Is done. In addition, “start time s−” is written as the reproduction range. “Start time” is an arbitrary number, and is a time stamp of a start point when moving image content is reproduced. The unit of the time stamp is, for example, second or frame. When only “start time” is written as the playback range, “s-” is written after “start time”, so that playback of a predetermined length of time from the start time of the moving image content can be performed. Done. The description of the reproduction range may be designated by, for example, “start time−end time” (where “end time” is an arbitrary number), thereby specifying the time stamp of the start point and end point. The description of the playback range may also specify the time stamp of the start point and the playback time from the start point.

  6b is a description for displaying a thumbnail image corresponding to a scene in the moving image content. Display of thumbnail images a to c in FIG. 5 is realized by the descriptions of 6a and 6b. 6c is an annotation given to the scene corresponding to the thumbnail images a to c. The display of “comment A” in FIG. 5 is realized by the description of 6c.

  In step S107, based on the thumbnail image displayed on the display device controlled by the client being selected by the viewer, the scene of the moving image content related to the thumbnail image is displayed on the display device.

  In FIG. 4, the operator who operates the client from step S101 to step S102, the viewer who gives the annotation in step S104, and the viewer who selects the thumbnail image and views the moving image content in step S107, respectively. It may be another user. If the viewer who gives the annotation in step S104 is different from the viewer who selects the thumbnail image and views the moving image content in step S107, a reward is paid to the viewer who gave the annotation by the affiliate mechanism. .

  FIG. 7 is a diagram for explaining a flow of an example of processing different from that in FIG. 4 for adding an annotation to moving image content. FIG. 7 shows an example of annotation assignment processing when an annotation for moving image content held by the moving image management server 1 is published as a web log article.

  In step S201 in FIG. 7, the HTML data generation unit 10 generates HTML data including the moving image content selected by the viewer. The HTML data generated in step S201 may follow a template for a web log article. The HTML data generated in step S201 may also generate HTML data for an annotated scene by obtaining an annotation corresponding to the moving image content from the moving image management database 23. . This makes it possible to generate highly convenient HTML data when further editing the annotation given during playback of moving image content.

  In step S202, the HTML data generation unit 12 edits the HTML data generated in step S201 based on the viewer operating the client. Step S202a is scene expansion / contraction editing, and step S202b is drag-and-drop editing.

  The scene expansion / contraction type editing is an editing realized by the HTML data generation unit 12 displaying the interface screen for scene editing on the client by the Web server 30, and the HTML data generation unit 12 adds the scene to the scene. A corresponding annotation and a plurality of thumbnail images corresponding to the scene are selected to generate HTML data, and the viewer selects a scene corresponding to the annotation from the thumbnail images displayed on the display device controlled by the client. This is an editing method in which the length of the scene is shortened based on the selection in units of frames. In scene expansion / contraction editing, the viewer may make a change to increase the length of the scene by pressing a predetermined button. Along with the change in the length of the scene, the viewer may edit the annotation by inputting from the input means. The annotation registration unit 11 registers the scene corresponding to the thumbnail image selected by the viewer as a new scene corresponding to the annotation in the moving image management database 23, and the HTML data generation unit 12 adds the scene to the scene. HTML data including a corresponding enlarged URL and thumbnail image is generated.

  The drag-and-drop type editing is an editing realized by the HTML data generation unit 12 displaying the interface screen for scene editing on the client by the Web server 30, and the HTML data generation unit 12 By generating HTML data including thumbnail images corresponding to each scene in the image content, the viewer moves the thumbnail images displayed on the display device controlled by the client to the editing area by drag and drop, This is an editing method for selecting a scene. If there is an annotation corresponding to the selected scene, the HTML data generation unit 12 acquires the annotation from the moving image management database 23 and displays it. The viewer performs editing of the displayed annotation or addition of a new annotation by inputting from the input means. The annotation registration unit 11 registers the selected scene and the annotation corresponding to the scene in the moving image management database 23, and the HTML data generation unit 12 includes HTML data including an enlarged URL and a thumbnail image corresponding to the scene. Is generated.

  In step S203, the HTML data generated in step S202 is browsed by the Web server 30. In step S204, the viewer selects the thumbnail image by clicking on the thumbnail image from the HTML data browsed in step S203, and the moving image content distribution unit 32 distributes the scene of the moving image content.
