Jitter buffer controller

摘要

Provided is a jitter buffer controller for controlling a jitter buffer (2) in which arrived packets are accumulated, including: a jitter measuring portion (8) for measuring jitter in the arrived packets; a judging portion (10) for judging whether or not the jitter of the packets can be absorbed with an accumulation capacity of the jitter buffer (2); a determining portion (6) for determining levels of importance of the packets; and a control portion (4) for reproducing or discarding packets in the jitter buffer (2), having jitter that cannot be absorbed with the accumulation capacity of the buffer, depending on a level of importance of the packets.
