Abstract:
A video telephone system comprising:an audio inputting unit for inputting first audio data;an audio compression means for compressing said first audio data to generate compressed audio data;an image inputting unit for inputting first image data;an image compression means for compressing said first image data to generate compressed image data;a multiplexing means for multiplexing said coded audio data and said compressed image data to form a transmission signal;a demultiplexing means for demultiplexing a reception signal to generate second audio data and second image data;an audio expansion means for expanding said second audio data to generate expanded audio data;an image expansion means for expanding said second image data to generate expanded image data;an audio outputting unit;an image outputting unit;an image processing numerical value specifying means for modifying arithmetic coefficients for processing said expanded image data;a processing switching means for transmitting said expanded audio data and said expanded image data to said audio outputting unit and said image outputting unit, respectively, in a first state, and for transmitting said expanded audio data and said expanded image data to said audio compression means and said image compression means, respectively, in a second state,said expanded image data being transmitted via said image processing numerical value specifying means to said image compression means in said second state.
