Patent ID: 8633963

Claim:
A method for determining buffer size based on retransmission latency, comprising: determining a retransmission latency between a first videoconferencing device and a second videoconferencing device; automatically determining a buffer size of a buffer of the second videoconferencing device based on the retransmission latency and a forward error correction (FEC) rate or ratio for transmissions between the first videoconferencing device and a second videoconferencing device, wherein the retransmission latency comprises a round trip time (RTT) between the first videoconferencing device and the second videoconferencing device; receiving a plurality of packets from the first videoconferencing device, including at least one FEC packet; determining at least one lost packet from the plurality of packets; transmitting a request for the at least one lost packet to the first videoconferencing device; receiving the at least one lost packet from the first videoconferencing device, wherein the buffer size allows for said receiving the at least one lost packet; and providing playback of the plurality of packets and the at least one lost packet.
