PURPOSE:To prevent lowering of transmission efficiency of short-period data by synthesizing the short period data and long-period data of n bits and sending it to the same transmission line in a transmitting side, and decomposing, rearranging and restoring this in a receiving side. CONSTITUTION:A transmitting device 10 inputs short-period data A1-An to a short-period data unit 11, and inputs long-period data B1-Bm to a long-period data unit 12. A CPU14 adds synchronizing data to data B1-Bm to produce long- period data, and decomposes bits L1-Ll of the long-period data into n bits, and adds decomposed bits L1-Ll and a parity bit P to the data A1-An to produce synthesized data, and sends this data to a transmission line through a transmission controlling unit 13. In a receiving device 20, a CPU24 decomposes the data A1-An and bits L1-Ll from the synthesized data rearranges them after plural samplings and restores the long-period data B1-Bm after executing program searching by detecting synchronizing data. The decomposed and restored data A1-An and B1-Bm are outputted through output units 22, 23 respectively. |
