Video conference control apparatus, video conference control method, and video conference control system

Abstract

A video conference control apparatus includes a decoding circuit, a thinning circuit, an image synthesizing circuit, an encoding circuit, and an encoding area setting circuit. The decoding circuit decodes terminal images received from a plurality of video conference terminals. The thinning circuit thins the terminal images decoded by the decoding circuit. The image synthesizing circuit multiplexes the terminal images thinned by the thinning circuit on a predetermined image frame, thereby generating a synthesized image. The encoding circuit encodes the synthesized image generated by the image synthesizing circuit. The encoding area setting circuit sets encoding areas while making the boundary between the encoding areas coincide with the boundary between corresponding divided window areas. A video conference control method and video conference control system are also disclosed.
