Abstract
PURPOSE:To attain picture transmission at a transmission speed in matching with the quality of a transmission line by adopting the constitution such that the transmission speed of the succeeding picture data by a transmission section is decided by the transmission speed decided by error number generated at the preceding picture data transmission by a reception section. CONSTITUTION:A transmission speed revision section 8 is provided to a transmission section 9 and the reception section 11 is provided with a reception speed revision section 12. In receiving a transmission data by the reception section 11 via a transmission line 10, when the error number of times NE at the preceding transmission is less than the set speed setting increasing set value NU, the succeeding transmission speed is increased more than that at present. Moreover, when the NE is more than the speed setting decrease number set value ND to be set, the succeeding transmission speed is decreased than that at present and when not more, the transmission speed no change is commanded. A transmission speed revision section 8 sends the data based on the decided speed. The reception section 11 revises the speed to the speed designated by the reception speed revision section 12.
