Abstract

PURPOSE:To reduce the cost by sending a code representing a transmission speed before speed conversion together with data and reproducing the transmission speed based on the reception side thereby coping with various kinds of transmission speeds and enhancing its versatility. CONSTITUTION:If the transmission speeds of data for transmission inputted to a transmission section A diversified, a speed code generating circuit 2 provided to the transmission section A detects the transmission speed of input data from a write clock 101 to the transmission speed conversion circuit 1 of the input data 102 and adds the transmission speed to the data 105 subjected to speed conversion as a speed code. Thus, by detecting the speed code added to the reception data, the reception side B recognizes the transmission speed of the input data 102 at the transmission section A. Since the readout by the clock signal recovered based on the detected transmission speed is implemented by the reception section B, the reception data at the same transmission speed as that of the transmission section A is obtained. Thus, the transmission and reception of an optional transmission speed are attained.
