COMMUNICATION SYSTEM, COMMUNICATION METHOD, TRANSMITTING TERMINAL AND RECEIVING TERMINAL |
摘要 |
<p>This invention related to a communication system using a terminal connected to a packet network. This invention is intended to predict and detect a congestion state between terminals and control congestion by delivering the packet according to the state. A receiving state monitor 4 calculates a moving average of jitter and a packet loss rate based on a packet received by a packet receiver 6. A controller 3 of a sending bit rate and an encoding rate obtains the moving average of jitter and the packet loss rate through a receiving state sender 8 and a receiving state receiver 7, judges the communication state, predicts a change in the communication state, and controls the sending bit rate and the encoding rate. <IMAGE></p> |
