Abstract:
1. A receiving device comprising: a buffer temporarily accumulating receive data received through a network; a data processing means for processing the receive data accumulated in the buffer; a short-time variation value acquisition means for acquiring a short-time variation value indicating variation of accumulated quantity of the receive data sequentially accumulated in the buffer in a first unit time; a long-time variation value acquisition means for acquiring a long-time variation value indicating variation of accumulated quantity in a second unit time longer than the first unit time; and a clock control means for controlling a clock frequency for performing processing of the receive data by the data processing means in accordance with evaluation results of the acquired long-time variation value, wherein the clock control means stops adjustment of the clock frequency when an error of the network or the receive data is detected based on the acquired short-time variation value, and starts adjustment of the clock frequency again after a given adjustment stop time passes from the detection of the error.
