VIDEO QUALITY ASSURANCE ACROSS IP NETWORKS: CHALLENGES, REQUIREMENTS WINNING STRATEGIES

摘要

As customers demand increasing flexibility to receive video services anywhere and anytime with the best possible quality of service, cable operators of all types have deployed IP next-generation networks, which provide new levels of scalability, flexibility and fault resilience, while acting as a platform for the rapid deployment of new video services. Operators will be challenged with monitoring and troubleshooting the growing number of video flows across these dynamic IP networks. A single lost IP packet can create visible artifacts on a large number of television screens, promoting the need for a new approach to video quality monitoring. A new set of technologies can be used to ensure high-quality transmission of video across an IP network, using network-centric and service-centric views. This new, integrated solution - bridging the gap between "IP engineers " and "video engineers " - enables cable operators to precisely isolate and rapidly resolve video issues, while providing a common reference for diverse operational groups that will reduce the duration of impairments and consequently reduce subscriber support calls.
