The design and implementation of a future Internet live TV system over 4G networks

摘要

The emerging 4G (fourth generation) networks featuring wider coverage, higher transmission bandwidth and easier deployment have a desirable potential to serve ubiquitous and pervasive multimedia applications in creating new user-centric communication services. However, the practical implementation of 4G network to demonstrate such potential, especially for delivering real-time and high-quality video services, is scarce. This paper therefore provides the design and implementation of a future Internet live TV system over 4G networks to achieve cost-effectiveness, instead of using expensive satellite news gathering (SNG) vehicle and costly satellite transmissions in traditional TV stations. To effectively provide live TV services, we apply not only the hybrid duplex modes but also the port-based VLAN on the deployed networks for maximizing bandwidth, minimizing signal interference, and guaranteeing QoS of differentiated services. Performance metrics are applied to demonstrate that the proposed solution is cost-effective and is feasible for live TV services in future Internet.
