Performance comparison of MPEG-4 scalable and non-scalable video streaming

Summary form only given, as follows. We first show that 3G wireless multimedia systems adopting scalable video encoding can achieve higher overall network utilization. Moreover, the problems of both packet loss and player rebuffering can degrade wireless streaming performance if the streaming video is non-scalable due to fading/retransmission and multi-user sharing. We demonstrate that these problems can be mitigated using a scalable video with rate control. The results indicate that MPEG-4 simple scalable visual profile is more suitable for wireless video applications than simple visual profile.
