PROBLEM TO BE SOLVED: To provide a moving picture compression coding transmitter, a receiver and a transmitter-receiver that can attain stable moving picture communication even among terminals different in throughput.;SOLUTION: A maximum decoding processing frame rate calculation section 5 calculates a maximum frame rate FRmax capable of real time decode processing from a frame coding processing time TE obtained from an image coding section 1 and a frame decoding processing time TD obtained from an image decoding section 11. A comparator section 3 compares the maximum frame rate FRmax with a maximum processing frame rate FRmax' at a receiver side received by a demultiplexer section 13 and inputs the frame rate which is smaller one to the image coding section 1. The image coding section 1 uses this received frame rate for a maximum frame rate to skip frames for coding control. As a result, even when the throughputs of both terminals are different from each other, the communication between both terminals can stably be conducted without exceeding the throughput.;COPYRIGHT: (C)2001,JPO
