In particular, about ten cameras are used for sports broadcasting, for example, baseball broadcasting, and about ten cameras are used for marathon broadcasting. The photographing operation is individually performed by a cameraman. In live broadcasting, the program organizer proceeds with the program while giving a specific instruction to each cameraman while watching a monitor image of a photographed image sent from each camera that changes every moment. When the programmer gives this instruction, the cameraman is identified by a code provided on the monitor in advance and a code provided on the camera to be used (usually 1, 2, 3,...,
A, B, C,..., Etc.) are matched in advance, and the program organizer calls the cameraman of the camera corresponding to the code attached to the monitor screen to which an instruction is to be given. Specifically, for example, "1 turtle", "A turtle"
The cameraman who has a camera corresponding to the monitor is referred to by a code-based name in the camera internal communication device, and communication between the program organizer and the cameraman is attempted.

The camera identification code is usually attached to a card, the camera identification card is detachably mounted on the camera side, and a camera control unit (CCU) or the like connected to the camera via a cable. Are also provided with the same reference numerals so that their associations can be clearly identified. The camera identification card is changed every day according to the number of cameras used and the cameraman who uses the cameras at the time of program creation, and is distributed and attached to each camera.

[0004] Therefore, since the photographer does not always give the same reference number to his or her own camera, the photographer performs a photographing operation while confirming the reference number given to his / her camera during photographing. I have.
