摘要：

In this paper, we investigate the scenario of wireless H.264 video transmission where selective-repeat ARQ has been adopted as an error control technique. While using ARQ can ensure reliable transmission, consecutive retransmissions cause the degraded PSNR and a lot of frames skipped. We then propose an improved rate-control by monitoring buffer occupancy and integrating channel throughput estimate for both frame and basic unit layers. Simulation results indicate our propose scheme can improve PSNR of up to 1.8 dB with no frames skipped, compared to that of H.264.
