  2. 2. 2 Presentation Overview  Problem  Solution: Statistical Multiplexing  Scalable Video Coding  Components of the Statistical Multiplexer  Objective Results  Perceptual Results  Demo  Questions
  3. 3. 3 Problem  Classical video multiplexing approach  Each video channel same bandwidth  However  Different content characteristics per channel => different quality between channels  Content characteristics change in time => quality varies in time  Result  Bad user experience
  4. 4. 4 Solution: Statistical Multiplexing  Dynamic joint rate allocation in function of content characteristics  New issues  Encoding?  Relevant content characteristics?  Joint rate allocation?  Bitrate adaptation?  Answers WP4.2
