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
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.
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
