PROBLEM TO BE SOLVED: To minimize the influence of data delay amount in data transmission to a device connected to a network.SOLUTION: The time synchronization device comprises: an input part for receiving a transmission signal from a transmission device, separating the received transmission signal into a time timing signal and a data signal, and outputting the separated signals; an output part for receiving the time timing signal and the data signal outputted by the input part, and transmitting the time timing signal and the data signal; and a delay time calculation part for calculating a delay time of the time timing signal from inputting of the transmission signal to the input part till outputting the data signal and the time timing signal from the output part. The output part transmits the delay time calculated by the delay time calculation part together with the time timing signal and the data signal. In addition, a communication network device for performing transmission/reception of data signal between the transmission device and a reception device includes the time synchronization device provided between the transmission device and the reception device.SELECTED DRAWING: Figure 3 |
