In this paper, we propose a scalable transport scheme for delivering on-demand video streams over broadband wireless networks in next-generation network/IP multimedia subsystem (NGN/IMS) architecture. The proposed transport scheme makes use of fine-granular-scalability (FGS) encoded videos to accommodate high bandwidth variation of wireless networks. We formulate the bandwidth allocation to FGS-encoded...
With the rapid development of broadband networks and multimedia technologies, P2P video-on-demand service is increasingly gaining popularity over the past few years. However, little work has been done on an important design issue for P2P video-on-demand systems, i.e., determining the maximal service capacity of a system. In this paper, we first propose an optimal rate allocation scheme to maximize...
