ABSTRACT:
In a video telephone system including an audio inputting unit, an audio compression module, an image inputting unit, an image compression module and a multiplexing module on a transmitting side, and a demultiplexing module, an audio expansion module, an image expansion module, an audio outputting unit, and an image outputting unit on a receiving side, an image processing numerical value specifying module modifies arithmetic coefficients for processing expanded image data, expanded by the image expansion module. A processing switching module transmits expanded audio data and expanded image data to the audio outputting unit and the image outputting unit, respectively, in a first state and also transmits the expanded audio data and the expanded image data to the audio compression module and the image compression module, respectively in a second state. In the latter case, the expanded image data is transmitted via the image processing numerical value specifying module to the image compression module.
