Abstract

A transmission device () outputs, to a reception device (), a stored amount of packets in a first transmission buffer () just before a certain packet has been written to the first transmission buffer. A first reception buffer amount read unit () in the reception device reads a stored amount of packets in a first reception buffer just before the certain packet has been read from the first reception buffer. A storage amount addition unit () adds the stored amount of packets in the first transmission buffer and the stored amount of packets in the first reception buffer, and a correction unit () adjusts the frequency of a variable frequency oscillator in a reception timestamp timerso that the resulting added value is a constant value.
