Provided are a data transmission system as well as data transmission method, data transmission apparatus and data reception apparatus which can maintain synchronization between transmission and reception even when the transmission apparatus, the reception apparatus and the transmission path do not operate on the same clock. <??>A data packet which is obtained by omitting a preamble or a parity or both of them from the data generated by the data generation means (111) and adding a data length field and spare bits is set as an access unit and is transmitted from the transmission apparatus (110) to the transmission path (100), and the reception apparatus (120) adds, to the received data, the preamble or the parity or both of them which have been omitted to reconstruct data, and adjusts the rate of data reading clock for transmitting data from the reception-side buffer means (124) to the data processing means (121) on the basis of the buffer accumulated amount in the clock control means (126). <IMAGE>
