Patent ID: 8743912

Claim:
A transmission system, having a transmitting device and a receiving device, which divides a series of data streams into a plurality of unit data and transmitting the plurality of unit data, wherein the transmitting device includes: a synchronization unit which outputs a clock signal synchronized with the receiving device by communicating synchronization unit data with the receiving device; a frequency change unit which changes a frequency of a time division multiplexing (TDM) signal on the basis of the clock signal output from the synchronization unit of its own device; and a conversion unit which converts the TDM signal with the changed frequency into the plurality of unit data and transmitting the plurality of unit data to the receiving device, and the receiving device includes: a synchronization unit which outputs a clock signal synchronized with the transmitting device by communicating synchronization unit data with the transmitting device; a decoding unit which receives the plurality of unit data from the transmitting device and generating the TDM signal with the changed frequency; and a frequency restoration unit which restores the TDM signal by returning a frequency of the TDM signal with the changed frequency to an original on the basis of the clock signal output from the synchronization unit of its own device.
