Video Flow – Between Triple Screen Systems

Max 4 Video StreamsCenter, Left and Right Camera = 3 Video streamsData 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

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

ProsPros

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

ConsCons

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
