Video source, carrier and client diversification led the video coding community to develop scalable video codecs supporting efficient decoding at varying resolution, frame rate and quality. Scalable video has a lot of advantages over a nonscalable approach, but a large scale deployment is far from trivial and a lot of open questions remain. To resolve these we developed, as part of the RESUME project, a complete video delivery chain for scalable wavelet-based video. This includes a video server, a negotiation framework, a video scaling infrastructure and two scalable video clients, one pure software client and one real-time, hardware accelerated client. This paper describes the complete chain and identifies and quantifies the impact of using scalable video in every link of this chain.
