A data transmission system, a data transmission method, a data transmission apparatus, and a data reception apparatus capable of maintaining synchronization of transmission and reception even when a transmission apparatus, a reception apparatus, and a transmission path are not operating with the same clock. A preamble, a parity, or both of them are deleted from data generated from data generating means (111) and a data length field and a backup bit are added, so as to create a data packet as an access unit which is transmitted from a transmission apparatus (110) to a transmission path (100). In a reception apparatus (120), the preamble, the parity, or both of them which have been deleted are added to the reception data so as to reconstruct the data. Clock control means (126) adjusts speed of data read out clock for transmitting data to data processing means (121) according to buffer accumulation amount from buffer means (124) of the reception side.
