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
Solution: Statistical Multiplexing
Dynamic joint rate allocation in function of content characteristics
New issues Encoding? Relevant content characteristics? Joint rate allocation? Bitrate adaptation?
