This paper presents an efficient switching method among non-scalable bit-streams in a multirate-based video streaming system. This method not only takes advantage of the high coding efficiency of non-scalable coding schemes (compared with scalable ones), but also allows a high flexibility in streaming services to accommodate the heterogeneity of real-world networks. One unique feature of our method is that, at every preselected switching point, the reconstructed frame at each rate or twodoi:10.1155/asp/2006/49084 fatcat:dqheychmwfbvxixyetdsthup3u
