Abstract
PURPOSE: To secure the coincidence of the directional feeling between the visual and acoustic senses and thus to realize a highly vivid TV conference by limiting the weight of the speakers at the receiver side in accordance with the speakers' positions at the conference.
CONSTITUTION: The conferece attendants A∼F are picked up through two units of TV camera 11 and 12 and then compounded via screen compounding circuit 20. On the other hand, the voice is sent to the receiver side through microphone mixture amplifier circuit 51 and 52 plus aural level detector circuit 61 and 62. The output detection signal of each microphone is converted into the control signal corresponding to the aural level through control signal production circuit 80 and then supplied to control signal adding circuit 30. The video signal at the receiver side is divided into two picture frames via control signal detector circuit 100 and picture frame dividing circuit 200 to be reproduced opposing to picture receiver 301 and 302 respectively. The aural signal is reproduced through amplifier circuit 500 plus sound volume control circuit 601 and 602 to speaker 701 and 702 in agreement between the voice source and the image of the speaker at the remote side.
