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