Telepresence systems

LifeSize ® Conference 200 ™ Page
Four 65+ 1080p30 High Definition TV for video and data sharing
Three 1080p30 HD cameras providing life-size coverage for 6 individuals
Touch Panel based Call Control and Directory lookup
One touch dialing to connect all three codec's simultaneously to the remote Telepresence Room
Standards based solution providing base level interoperability with similar Telepresence solutions
Point-to-Point Telepresence plus integration with MCU-based Telepresence solutions
Video Only Audio. Video, Data

Video Flow – Between Triple Screen Systems
Max 4 Video Streams
Center, Left and Right Camera = 3 Video streams
Data Video = 1 Video stream
All Video Streams share 1 common RTP Connection
Each Camera stream is sent to the corresponding Display
Data Video stream is sent to the Projector HDMI Outlet
Only either Doc Cam or the PC Input would be active at a time
Video RTP Session CTS 2 CTS 1 or

Native Interoperability How Polycom Does it HDX 4000 Continuous Presence High Definition HDX or VSX Group Systems TPX 306M TPX 306M RPX 200/400 RMX Other Group Systems Point-to-point dialing H.323/H.320/SIP H.323/H.320/SIP

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 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
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.
Pros Cons

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
