摘要

Packet loss may lead to serious degradation of video quality in network communication. Sometimes a router must drop quite a lot of packets to alleviate the congestion. This paper designs multiple dropping schemes for H.264 videos, considering varying packet loss rates We perform packet dropping experiments for three video sequences. Experiment results show that both the packet type and the packet distribution have an impact on the video quality. Given higher packet loss rates, dropping a few B frames in a GOP results in less quality degradation than dropping packets randomly from all the B frames.
