Data reception device

摘要

A data reception device includes: a reception data buffer unit for storing a plurality of packets contained in a data packet; a reception data amount measuring unit for measuring the data amount stored in the reception data buffer unit; a variable clock generation unit for generating a clock having a variable frequency; a time information output unit for outputting second time information counted in accordance with the frequency of the clock generated by the variable clock generation unit; and a first time information comparison unit for comparing the first time information added to the packets with the second time information outputted from the time information output unit and for controlling the timing of outputting the packet stored in the reception data buffer unit. The reception data amount measuring unit controls the frequency of the clock generated by the variable clock generation unit in accordance with measured values obtained by the reception data amount measuring unit.
