  The image reference button B1 displays a list of image files in the blog creator terminal 100A, and designates the moving image file IMG2 to be posted in the trackback article (step S68). Then, the moving image file IMG2 designated in step S68 is displayed on the posting screen.

  Next, in the moving image file IMG2, a part of scenes (link images) to be displayed on the blog article of the citation source is specified (step S70). In step S70, as shown in FIG. 6A, on the trackback article posting screen, a screen (film roll) IMG2 ′ that displays the frames of the moving image file IMG2 sequentially or every few frames while flowing in the horizontal direction of the drawing. Can be specified by clicking the first frame (start frame) and the last frame (end frame) of the scene used as the link image with the mouse of the operation unit 104. When the frame designation button B4 is clicked, the designated frame designated in step S70 is confirmed (step S72), the frame numbers of the start frame and the end frame are detected (step S74), the moving image file IMG2 and the designated frame are designated. Link image specifying information for specifying a frame is generated (step S76). The link image specifying information is represented by a frame designation URL as shown below, for example.

[Example of frame designation URL]
http://blog.xxx.ne.jp/userid/12345.htm?pic=http://00/abc.mpg?f1=20&f2=50
In the frame designation URL, the character string “12345.htm” is the file name of the trackback article, and the argument “pic = http: //00/abc.mpg” is the movie file IMG2 designated in step S68. File name (full path). The arguments “f1 = 20” and “f2 = 50” represent the start frame and the end frame of the moving image file IMG2 used as the link image, respectively. In the frame designation URL, the character string “?” Is a delimiter between the file name and the argument, and the character string “&” is a delimiter between the arguments.

  Next, an input of a trackback ping URL (TrackBack-Ping URL, see FIG. 8A) is accepted in the trackback destination URL input field C3 (step S78). When the determination button B3 is clicked, the trackback article is edited. The contents (title, text, video, etc.) are confirmed (step S80), and the confirmed trackback article, trackback ping URL, and frame designation URL are transmitted to the information distribution apparatus 10A (step S82).

  Next, when the trackback article is received by the information distribution apparatus 10A (step S84), as shown in FIG. 9B, the trackback article is distributed by the information distribution apparatus 10A (step S104). The trackback article browsing screen shown in FIG. 9B displays the title of the trackback article, the body text, and the moving image file IMG2, and is provided with a reproduction button for reproducing the moving image file.

  In addition, when the trackback article is received in the information distribution apparatus 10A (step S84), a trackback request is transmitted to the information distribution apparatus 10B distributing the blog article of the citation source (step S86). The trackback request includes the link image specifying information (frame designation URL).

  Next, when the information delivery apparatus 10B receives the trackback request from the information delivery apparatus 10A (step S88), the received frame designation URL is analyzed, and the moving image file IMG2 designated by the frame designation URL is requested. To be transmitted to the information distribution apparatus 10A (step S90).

  Next, the moving image file IMG2 transmitted from the information distribution apparatus 10A is received, and the specified frame (start frame, end frame, and frames between them) of the moving image file IMG2 specified by the frame specifying URL is a moving image file. It is cut out from IMG2 and stored (steps S92 and S94). In addition, text information such as the title and body of the trackback article transmitted from the information distribution apparatus 10A, link information (URL), and the like are received and stored (steps S96 and S98).

  Next, in the information distribution apparatus 10B, as shown in FIG. 8B, character information such as a title to the trackback article (“Today's ○ △ -chan”) and a part of the text is included in the blog article of the citation source. The moving image and link information (URL) of the frame range stored in step S94 are added, and the blog article of the citation source is updated (step S100) and distributed (step S102).

  According to the present embodiment, when creating a trackback article by quoting another person's blog article, the blog creator designates a part of the video used for the trackback article and tracks the blog article of the citation source. Can be displayed.

The quotation source blog article is displayed on the display unit 102 of the blog creator terminal 100A (step S112).

  Next, in step S114 and subsequent steps, trackback processing is performed on the blog article of the citation source. First, in the blog creator terminal 100A, communication is started between the blog creator terminal 100A and the information distribution device 10A by a predetermined operation input from the operation unit 104, and a trackback article posting screen is displayed from the information distribution device 10A. After being distributed (step S114), a trackback article posting screen is displayed on the display unit 102 of the blog creator terminal 100A. Then, editing processing such as inputting character information of a trackback article and selecting a layout is performed from the operation unit 104 (step S116).

  FIG. 13 is a diagram illustrating an example of a trackback article posting screen.

When the determination button B3 is clicked, the trackback article is edited. The contents (title, text, image, etc.) are confirmed (step S124), and the confirmed trackback article, trackback ping URL, and area designation URL are transmitted to the information distribution apparatus 10A (step S126).

  Next, when a trackback article is received in the information distribution apparatus 10A (step S128), as shown in FIG. 13B, the trackback article is distributed by the information distribution apparatus 10A (step S156).

  In addition, when a trackback article is received in the information distribution apparatus 10A (step S128), a trackback request is transmitted to the information distribution apparatus 10B that distributes the blog article of the citation source (step S130). The trackback request includes the link image specifying information (image designation URL).

  Next, when the information distribution apparatus 10B receives the trackback request from the information distribution apparatus 10A (step S132), the received image designation URL is analyzed and the image file IMG3 designated by the image designation URL is requested. Is transmitted to the information distribution apparatus 10A (step S134).

  Next, the image file IMG3 transmitted from the information distribution apparatus 10A is received (steps S136 and S138), and a face recognition process is tried for the image file IMG3 designated by the image designation URL (step S140). When a face area is detected from the image file IMG3 (Yes in step S142), an image including the face area is cut out from the image file IMG3 (step S144). On the other hand, when no face area is detected from the image file IMG3 (No in step S142), the image file IMG3 is used as it is as a link image (step S146).

  Next, text information such as the title and text of the trackback article transmitted from the information distribution apparatus 10A, link information (URL), and the like are received and stored (steps S148 and S150).

  Next, in the information distribution apparatus 10B, as shown in FIG. 12 (b), text information such as a title to the trackback article (“New Party 0Δ”) and a part of the text, etc. Link information (URL) is added.
