We will be receiving Joachim Bruneau-Queyreix from CNRS-LaBRI – University of Bordeaux – Bordeaux INP who will give a talk about Tomorrow’s video streaming issues and (some) solutions on Monday, June the 17th.
Abstract: Single-source HTTP Adaptive Streaming solutions (HAS) have become the de-facto solutions to deliver video over the Internet mostly due to their capabilities to increase end-user’s Quality of Experience (QoE) as well as their ease of deployment due to the usage of the HTTP protocol. Although HAS solutions can increase QoE by trading off the delivered video quality to minimize the number of video freezing events, they are limited by the bandwidth available on the considered communication channel between the client and the server. This presentation exposes contributions in building pragmatic evolving solutions advocating for the simultaneous usage of multiple sources with heterogeneous capacities so as to achieve high QoE content delivery at low cost. The first presented contribution is a streaming solution extending HAS capabilities to the usage of multiple servers: MS-Stream. MS-Stream provides the means to exploit expanded bandwidth and link diversity in distributed heterogeneous network infrastructures. MS-Stream comes with a set of client-side consumption and adaptation algorithms aiming at increasing the end-user’s perceived streaming quality while utilizing the most of the heterogeneous capacities offered at the service and network environments. We further extend MS-Stream by leveraging on clients’ connectivity capacities and we expose a hybrid P2P/Multi-server live-Streaming system (PMS) incorporating distributed quality and scalability adaptation mechanisms.
Bio: Joachim Bruneau-Queyreix is an Associate Professor at Bordeaux-INP since september 2018, he joined the CNRS-LaBRI lab as a permanent researcher in the PROGRESS team. His research focuses on distributed systems and security including the recent advances on trusted-execution-environment, blockchain, and video streaming. Prior to joining CNRS-LaBRI as a permanent member, Joachim enrolled as a research fellow at the National Institute of Telecommunications in Warsaw Poland for a year. He obtained his Ph.D from the University of Bordeaux in 2017.
