Abstract
A system utilizes the camera control server of the CPU to transfer the camera control command, received through the network, to the camera control device to control the camera in order to vary the audio input/output characteristics in linkage with the camera operation and to thereby improve the realistic feeling. In more details, the camera control server also sends control commands to the audio input control device, the audio output device and the video display control device according to the camera control thereby controlling the input characteristics (spreading, direction and sensitivity) of the microphone and the output characteristics (spreading, direction and depth) of the speaker and varying the image displayed on the monitor. The system also includes technology for displaying, on the monitor, the information on the operator of the camera and on the receiver of the image, and for varying the direction of the monitor according to the panning or tilting operation of the camera.
