Abstract
A multimedia communication apparatus can perform communication while multiplexing multimedia information comprising voice information, video information, data and the like. If the transmission rate of video information in a first channel is greater than a predetermined value, a new additional channel is not connected even if a plurality of channels are connectable. It is thereby possible to automatically set the minimum number of channels necessary for the communication of video information, and to prevent setting of an unnecessary additional channel.
