Abstract

The present technology pertains to a synchronization processing device a synchronization processing method and a program which make it possible to achieve frequency synchronization in a shorter period of time. A jitter amount calculation unit calculates a jitter amount on the basis of a synchronization packet comprising time information. A jitter accumulation unit calculates a cumulative value of the jitter amount calculated by the jitter amount calculation unit. A comparison unit outputs a frequency error correction value from the calculated cumulative value of the jitter amount. A control voltage generation unit outputs a frequency control voltage that is based on the frequency error correction value. The present technology can be applied to for example a receiver device that is time synchronized with a transmission device.
