摘要: Live SNG (Satellite News Gathering) services, featuring real-time streaming of high-quality video, are typically enabled via expensive vehicles and satellite transmissions by TV companies. In this paper, we design a cost-effective solution to delivering live news broadcasting (LNB) service over emerging broadband wireless access technologies such as WiMAX. However, LNB is bandwidth hungry may consume most the uplink resource. Besides, conditions shared between mobile nodes base stations (BSs) vary with time location, which affect quality (QoS) service. To guarantee QoS level service, implement novel system called i-SNG uses multi-link SCTP glue together more from heterogeneous networks WiMAX, 3.5G cellular, WiFi, ensure fault tolerance for LNB. We share our experience in constructing an experimental test-bed proposed apply new patch FreeBSD 7.1 test-bed. The results show that not only provides but also preserves perceptual video under different network
