Patent ID: 8693333

Claim:
A method for suppressing lost packet retransmission, comprising: generating retransmission suppression information, wherein the retransmission suppression information comprises identification information of data packets requiring retransmission suppression; and transmitting the retransmission suppression information to a receiving node by using an extended Real-time Transport Protocol (RTP) Control Protocol (RTCP) packet, wherein the retransmission suppression information is used to enable the receiving node not to request retransmission when data packets corresponding to the identification information in the retransmission suppression information are lost after the receiving node receives the retransmission suppression information; wherein the transmitting the retransmission suppression information to the receiving node by using the extended RTCP packet comprises: transmitting the extended RTCP packet using packet sequence numbers of a first packet and a last packet requiring retransmission suppression as the retransmission suppression information to the receiving node, when sequence numbers of packets requiring retransmission suppression are consecutive.
