Abstract
There is provided a receiving device including: a receiving unit that receives a packet stream; an oscillator; a measuring unit that performs a measuring operation; an acquiring unit that reads the newest time stamp read from the packet stream received by the receiving unit and the newest measurement value measured by the measuring unit with a predetermined period, from a point of time when the packet stream starts to be received; a calculating unit that calculates an accumulation value of the time stamps and the measurement values acquired by the acquiring unit; a comparing unit that compares a difference between the accumulation value of the time stamps and the accumulation value of the measurement values calculated by the calculating unit, and a value corresponding to a network jitter; and a frequency control unit that controls the oscillation frequency of the oscillator based on the comparison result by the comparing unit.
