  • Determining buffer size based on retransmission latency
    Patent number: 8633963
    Abstract: Determining a buffer size in a videoconference. In some embodiments, one or more of various different error correction methods may be used in a videoconference. For example, forward error correction (FEC) may be used and/or retransmission of lost packets (ReTxLP) may be used, e.g., based on a packet loss threshold. Where FEC is used, a buffer size of a receiving videoconferencing device may be determined based on the FEC rate. Where ReTxLP is used, a buffer size of the receiving videoconferencing device may be determined based on a retransmission latency.
    Type: Grant
