Abstract
A multimedia communication apparatus or system is able to display an undisturbed image if image transmission is suspended during audio visual (AV) communication. If the hold-key of the operational unit of an apparatus is pressed during multimedia communication, the system control unit suspends audio and image signals for transmission, and transmits a suspension command to a communication-partner apparatus. When the communication-partner apparatus receives the suspension command, the video interface thereof freezes an image currently received, and the image memory stores this frozen image. Then, the video interface shifts its output to the display from the images received from the video coder-decoder to the frozen image stored in the image memory. The display thus displays the frozen image during the communication suspension. Further, if image transmission is suspended, a transmission capacity including a capacity for image information is used to transmit information regarding the suspension.
