Abstract

PURPOSE: To enable to judge the video quality of the received picture at the transmission side and to reduce the video transmission time, by returning a part of the received picture to the transmission side with detection.
CONSTITUTION: The interface 3A of the transmission side A transmits the information from the read-in section 1A to the reception side B and records the local picture 16A via the write-in section 10A. Further, at the receiving end B, the picture memorized in the write-in section 10B is obtained as the local picture 16B. Then, the corresponding part of the recorded picture by the write-in sections 10A and 10B are respectively detected with the concentration detection means 18A and 18B and the integration value of concentration is obtained. The integration value of the means 18B is returned to the transmission side A, where it is compared with the integration value of the means 18A resulting in judging the received video quality.
