Channel Set Adaptation: Scalable and Adaptive Streaming for Non-Linear Media
Technologies that stream linear media objects, such as audio and video, are in wide use on the Internet. Large groups of users regularly tune in to a variety of online programming, including radio shows, sports events, and news coverage. However, non-linear media objects, such as large 3D computer graphics models and visualization databases, have proven more difficult to stream at scale due to their interactive nature. The Channel Set Adaptation (CSA) project provides a framework that allows for the efficient streaming of non-linear datasets to large user groups. CSA allows individual clients to request custom data flows for interactive applications using standard broadcast or multicast join and leave operations. CSA scales to support very large user groups while continuing to provide interactive data access to independently operating clients.
In addition to the core CSA algorithm, this project examines many related topics such as alternative multicast algorithms (StrandCast), a general model for user-driven adaptation (GAL), and applications to digital museums. More details on these various technologies can be found in the publications listed below.
