摘要

We study packet streaming over an erasure channel with delayed feedback. We consider the lag in playback between the sender and the receiver as the performance criterion and propose and analyze schemes to minimize the lag. We show that at lower delays in feedback, purely retransmission based schemes are better than random linear coding schemes and also analyze the tradeoff of the lag with the delay in feedback.
