PROBLEM TO BE SOLVED: To dynamically change transmission format information. ;SOLUTION: A video/audio transmitter-receiver is provided with a reception management section 11 that receives information including data and its transmission format information from a storage device and a communication channel, a separation section 12 that analyzes the received information and separates it, a transmission section 13 that sends information to the storage device and the communications channels, and an image expansion section 14 that expands image data. An image expansion management section 15 manages a processing state of the image expansion section 14 that expands at least one image or over. Then an image composite device consisting of an image composite section 16 that composites images based on the expanded information, of an output section 17 that outputs the result of composite, and of a terminal control section 18 that controls and manages each means composites a plurality of images simultaneously and copes with dynamic changes in transmission format information.;COPYRIGHT: (C)1999,JPO
