The paper, titled "GroupCast: Preference-Aware Cooperative Video Streaming with Scalable Video Coding," proposes a preference-aware cooperative video streaming system for videos encoded using Scalable Video Coding (SVC) where all contributing users are interested in watching the same video on a single screen. The quality decisions of video chunks and fetching policy of the SVC layers subject to the available bandwidth, chunk deadlines, and cooperation willingness of the different users is formulated as an optimization problem and efficient algorithms are proposed. Optimality guarantees and online adaptations are provided, and extensive simulations driven by real SVC encoded video and real bandwidth traces of a public dataset reveal the robustness and high-performance of the proposed scheme.
