PROBLEM TO BE SOLVED: To provide a relay unit which can amplify data, by confirming only the first piece of information of a received data signal to determine that it is the data to be amplified, and can transmit and receive the data signal smoothly, by decreasing a transmission delay due to sorting of data and preventing distortions of the data transmitted or received. SOLUTION: The relay unit includes a first signal processor for filtering and amplifying a received data signal, a path controller for transmitting the first piece of information of the received data signal, through a first path and transmitting a data signal subsequent to the first piece of information through a second path, a second signal processor for amplifying and sending the data signal transmitted, through the second path of the path controller, and a data sorting processor for controlling the path controller to transmit the data signal subsequent to the first piece of information through the second path, when the received data signal is decided as being specified local data, by using the first piece received through the first path of the path controller.
