Stochastic optimal control of HTTP Adaptive streaming 

Julián Cabrera Quesada, Universidad Politécnica de Madrid

12-1pm  24th Oct 2017 

HTTP Adaptive Streaming (HAS) is becoming a key technology for audiovisual broadcasting through IP networks. This technology has been adopted and developed by important vendors such as Microsoft, Apple or Adobe and the creation of an MPEG standard (MPEG-DASH) has also contributed to its success for multimedia broadcasting. Important IP content providers such as Netflix, Amazon, HBO etc., are using this technology for their video on-demand services, and traditional IPTV providers such us Movistar TV, are also moving to this technology for their live broadcasting services. One of the key elements in HAS technology is the player at the client side which has to make decisions in order to provide the best possible video quality. These decisions have to consider the dynamic network conditions, the device features and the user ́s profile and preferences. In this talk, the behaviour of the player will be described and formulated as a Markov decision problem and solutions based on Stochastic Dynamic Programming and Reinforcement learning will be presented. More info
