<p>A plurality of pieces of information concerning the relay device are notified to a terminal unit. A storage section (1b) stores data items having order information (e.g. sequence numbers) added thereto, received from a transmitting-end device. A transmission order controller (1a) reads out the data items from the storage section (1b) such that the data items are transmitted in an order corresponding to information to be notified to a receiving-end device (2), and transmits the data items. This enables a detecting section (2b) of the receiving-end device (2) to detect that a receiver (2a) thereof has received the data items the sequence numbers of which are arranged not in an order of 1, 2 and 3 but in an order of 3, 1 and 2, for example, and detect that information corresponding to this order has been transmitted from the relay device (1). A rearrangement controller (2c) rearranges the data items received by the receiver (2a) based on the sequence numbers in an order of the sequence numbers, and outputs the data items.</p> |
