Hybrid Transmission Approaches for Video-on-Demand System

Abstract

DefinitionTo compensate for the disadvantages of the client-server approach and peer-to-peer approach for video transmission, a number of hybrid approaches have been proposed recently.Due to the expensive deployment and maintenance of proxy server, the stringent requirement for video broadcasting in a single server, and the dynamic nature of peer-to-peer (P2P) transmission, a number of hybrid approaches have been proposed to take the benefit of either approach for video transmission recently.Xu et al. [1] proposed a CDN-P2P architecture that integrates both P2P and CDN (Content Distribution Network) to provide a cost-effective solution for video services. In this architecture, these two technologies complement each other. The distribution process of video data in this framework involves three stages. When the system is launched, the system first enters into an initial stage. In this stage, the requesting peers are served by the CDN server directly. During obtaining the video ...
