BIDIRECTIONAL COMMUNICATION IMAGE COMBINING SYSTEM, BIDIRECTIONAL COMMUNICATION IMAGE COMBINING APPARATUS, BIDIRECTIONAL COMMUNICATION IMAGE COMBINING METHOD, AND ITS PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a bidirectional communication image combining apparatus capable of reducing a gap between a voice and an image.

SOLUTION: A CM image sending controller 11 is designed to perform output and selection control of CM image data based on a decoding result of a tone signal from DTMF decoders 18, 19. A CM image data macroblock decoder 13 is designed to decode the CM image data read out from a CM image data accumulating unit 12 by macroblock units. Image data macroblock decoders 14, 15 are designed to decode the image data to be transmitted between a transmission side terminal and a reception side terminal via a bidirectional communication by macroblock units. An image data macroblock mixers 20, 21 are designed to perform a superposing process by the macroblock units relating to each decoded image data. Image data macroblock encoders 16, 17 are designed to output the superposed image data by the macroblock units after encoding.
