I have watched a TV episode and it was great. Definition was fine. It works well 90% of times. I started watching the episode quickly and the episode was not abnormally interrupted. Definition was not too bad. means

6. Concertation Meeting, Brussels, 3rd February 2010Slide 6© COMET COMET aims to provide a unified interface for content access whatever the content characteristics are: –temporal nature (pre-recorded or live), –physical location (centralised or distributed), –interactivity requirements (elastic or real-time), or –any other relevant features It also aims to apply the most appropriate end-to-end transport strategy: –By mapping the content according to its requirements and user preferences to the appropriate network resources best quality of experience for end users –All different types of content distribution will be supported: Unicast, anycast, multicast… The COMET project Top-level objectives … while preserving network availability and structural resilience, as key factors in perceived QoE

9. Project oriented to practice –Focused on practical objectives: satisfaction of actual demands We should solve something demanded by someone –Feasible: Technically possible Scalable (for actual deployments) –Demonstrable in practice Proof-of-concept prototypes in realistic network testbeds Scalability and performance evaluated through theoretical studies and simulations. Project oriented to standardization and dissemination Internet-wide scope Required to influence Industry Concertation Meeting, Brussels, 3rd February 2010© COMET 2009Slide 9 Our objectives, briefly Project orientation
