9. Current TANDBERG solution basics  Three codecs  Multiple H323 calls  External control unit which controls all three codecs  Proprietary solution for signaling left and right codecs  Uses non-standard userInput messages in H.245 Site A Site B

10. Pros Pros and Cons for current solution  Easy to implement  Easily extensible  Few components needed to change  Good solution for firewall traversal  General interoperability with non-telepresence systems  Works very well together with Telepresence-specific MCU Cons  Proprietary  Long call setup  Multiple calls = multiple licenses  Calls  Firewall traversal  Registrations  Hard to do bandwidth control  Goes against normal call setup  Each camera maps to 1 and only 1 output screen.

11. Some ideas to requirements  N audio-streams, M video-streams  Positional information of those streams  Generic support for tagging streams  Maintaining backwards compatibility  Extremely low call-setup time  Firewall traversal  Encryption  Audio energy level as metadata  Minimum media type support  Generic support for capabilities exchange  Extensibility: –H.241-like signalling of H.264 capabilities –H.245 generic types –Future audio and video codecs N and M are [0,1,2,3,...] N=M=1 <1 second
