Abstract:
1. A packet processor for processing packets of data received via a network to reproduce the data, comprising: a receiving buffer for storing received packets; a reproducing means for reproducing data of the packets based on a reproduction clock; and a control means for performing control so as to reproduce data without breaks, wherein the control means controls the packets stored in the receiving buffer by their number without using temporal information received with the packets, holds a reference value for the number of received packets, which is determined beforehand, and causes the reproducing means to start data reproduction when the number of packets exceeds the reference value; monitors a state of the receiving buffer and collects, when the packets in the buffer are used up, packets up to a level corresponding to the reference value before causing the reproducing means to restart data reproduction; and monitors the number of packets in the receiving buffer at intervals of a predetermined time period, and when a result shows increase or decrease in the number of packets with time, the control means, based on the result, modifies a receiving buffer size and the reference value for the number of received packets at which reproduction of data is started.
