Abstract

PURPOSE:To evaluate the video quality of a reception original at the transmission side, by receiving a return request signal from the transmission side, returning the reception picture stored in a memory at the reception side as a return video signal, and demodulating and recording it at the transmission side. CONSTITUTION:A transmission side 1 is provided with a reader 11, modulation and demodulation device 12, recorder 14, and control circuit, and a reception side 2 is provided with a modulation and demodulation device 22, reader 21, memory 26, recorder 24 and control circuit 23. When a return request signal generated from a return request signal generator 15 at the transmission side 1, the signal is given to the modulation and demodulation device 22 and circuit 23 at the reception side 2 via the modulation and demodulation device 12. Thus, the circuit 23 reads out a reception video signal from the memory 26, this signal is modulated at the device 22 and transmitted to the transmission side 1 as the return signal. The controller 13 at the transmission side 1 demodulates this signal at the device 12 and records it as picture.
