Abstract :
Using multiple channels to broadcast a popular video can reduce the viewer´s waiting time to approach video-on-demand service. In this paper, we discuss the major weakness of mirrored-pyramid broadcasting (MPB) scheme and propose an enhanced scheme. The performance study shows that in the enhanced scheme, up to 50% of network bandwidth can be saved for the same performance in MPB. Our enhanced scheme also achieves a better access latency and a smaller buffer requirement in the video-on-demand service under the same resource requirements
