| Abstract(in English) | When a considerable amount of UDP traffic is injected into the Internet by distributed multimedia applications, it is easily driven congested. Consequently, bandwidth available to TCP connections is oppressed and their performance significantly deteriorates. In order that both multimedia applications and TCP-based ones fairly co-exist in the Internet, it becomes increasingly important to consider the inter-protocol fairness. In this paper, to take into account the quality degradation caused by packet loss in video quality adaptation, we propose the video quality adjustment mechanisms which accomplish the high-quality, stable, and TCP-friendly video transfer under a lossy environment in cooperation with the FEC (Forward Error Correction) technique. Our mechanism adjusts the video quality in accordance with the TFRC (TCP-Friendly Rate Control) rate, the packet loss probability, and the video quality. Through simulation experiments, we show that our proposed method can provide high-quality, stable and TCP-friendly video transfer even in the unstable and lossy Internet. |
