摘要

A data transmission system comprising a receiving device for receiving data to which a pair of error correction codes consisting of product codes is added, one error correction code having a data arrangement identical with the order in which the receiving device receives the data, a temporary storage device for storing the data temporarily, an error sensing device for sensing errors in one error correction code, before storing the data in the temporary storage device, an error correcting device for correcting errors in the data stored in the temporary storage device, the error correcting device executing erasure correction of the other error correction code by using information on errors in one error correction code sensed at the error sensing device, and a transmitting device for transmitting the data whose errors have been corrected by the error correcting device.
