摘要： Methods for adapting the sliding window of sliding window-based error correcting codes based on the coding structure of a compressed media stream are disclosed. In one aspect, a sender packetizes each frame of a media stream to be sent to a receiver into a set of frame packets. The sender also determines compression dependence of each frame and adapts a sliding window of a sliding window-based error correcting code based on the compression dependence of the frame. The sender encodes the frame packets into at least one associated parity packet according to the error correcting code with the adapted sliding window, and sends the frame packets and the at least one associated parity packet to the receiver.

摘要： According to one embodiment, video data from a video transmitter (110) is received (420) at a network buffer (130). Information that pertains to a network buffer drain rate (14) of the network buffer (1q3) is monitored (430). The network buffer drain rate (140) is a rate that the video data is removed from the network buffer (130). The network buffer drain rate (140) is estimated (440) based on the monitored information. A transmission rate (120) that the video transmitter (110) transmits future video data is adjusted (450) to not exceed an allowed transmission rate (ATR) that is calculated based on the estimation of the network buffer drain rate (140).
