[Video attribute information table generation method]
In the first to third embodiments described above, the video attribute information table may be created as follows.
FIG. 17 is a diagram showing an outline of a place where the camera 100 is installed. In FIG. 17, five cameras 100 (100-1 to 100-5), a display control device 700, and a display device 800 (800-1 to 800-3) are installed. Camera 100-1 captures the display surface of display device 800-3, camera 100-2 captures the left side of the display surface of display device 800-2, and camera 100-3 captures the display surface of display device 800-2. The center 100 is photographed, the camera 100-4 photographs the right side of the display surface of the display device 800-2, and the camera 100-5 images the display surface of the display device 800-1. The display control device 700 controls display contents on the display surfaces of the display devices 800-1 to 800-3. In addition, the display control device 700 generates a video attribute information table according to the display contents on the display surfaces of the display devices 800-1 to 800-3. The display control device 700 transmits the generated video attribute information table to the distribution information management server 600.

  The camera attribute storage unit 701 is configured using a storage device such as a magnetic hard disk device or a semiconductor storage device. The camera attribute storage unit 701 stores a camera attribute table. The camera attribute table is a table in which video identification information of video data generated by the camera 100 is associated with information indicating the position of the video screen shot by the camera 100. For example, video identification information of video data shot by the camera 100-1 is associated with the position of the video plane shot by the camera 100-1 (display surface of the display device 800-3).

The display position control unit 702 controls characters and images displayed on the display surfaces of the display devices 800-1 to 800-3. The display position control unit 702 displays information on its own control content (attribute information regarding characters and images displayed on the display devices 800-1 to 800-3 and information indicating their positions) as a video attribute information table generation unit. Output to 704.
The communication unit 703 communicates with the distribution information management server 600 via the network 500.

  The video attribute information table generation unit 704 generates a video attribute information table based on the camera attribute table stored in the camera attribute storage unit 701 and the control content information output from the display position control unit 702. Specifically, the video attribute information table generation unit 704 converts the attribute information related to characters and video displayed on the video screen shot by each camera 100 to video identification information of video data shot by each camera 100. By associating, a video attribute information table is generated. For example, when the vocal face is displayed up on the display device 800-3, the video attribute information table generation unit 704 performs “vocal” on the video identification information of the video data captured by the camera 100-1. The video attribute information “Face Up” is associated. For example, when a character string (comment) posted by a user whose user identification information is “U0002” is displayed in the center of the display device 800-2, the video attribute information table generation unit 704 uses the camera 100-3. Video attribute information “U0002” and “comment” are associated with video identification information of video data to be shot.

  The video attribute information table generation unit 704 transmits the generated video attribute information table to the distribution information management server 600 via the network 500. When receiving the video attribute information table from the display control device 700, the distribution information management server 600 records the received video attribute information table in the video attribute information storage unit 602.
