Abstract
A data transmission system maintaining synchronization between transmission and reception even when a transmission apparatus, a reception apparatus and a transmission path do not operate on the same clock. Specifically, data packet is obtained by omitting a preamble and/or a parity from data generated by a data generation means and by adding a data length field and spare bits. The obtained data packet is set as an access unit and is transmitted from a transmission apparatus to a transmission path. A reception apparatus adds, to the received data, the preamble and/or the parity to reconstruct data, and adjusts a rate of a data reading clock for transmitting data from a reception-side buffer means to a data processing means a the basis of an accumulated amount in a clock control means.
