Doing Both: TIP and Telepresence Activity Groups

Doing both means avoiding either/or choices and approaching every decision as an opportunity to seize.
For IMTC, it means each Telepresence related activity group can benefit from its leadership and mutually reinforce the other for the ultimate benefit of the industry.
Those wanting an interoperability option now can use TIP as well as participate in its stewardship while the Telepresence AG is contributing to new, openly develop standards for multi-streaming that are getting under way.

Cisco originally designed and developed the Telepresence Interoperability Protocol (TIP), which it opened up to others to license earlier this year.
When asked to divest its ownership of TIP and hand it over to a responsible industry body to govern its future, Cisco asked IMTC because of its rich history of driving interoperability in the multimedia communications industry.

To help speed your implementation of TIP, there is also an open source TIP Library project available from IMTC under the friendly, Apache 2.0 License.
IMTC will facilitate TIP product interoperability testing events and host ongoing discussions around enhancements or changes needed to TIP to help ensure multi-vendor success.

Insight gained from the experiences of an early implementation, even if originally proprietary, can be very valuable to future standards designers and adopters alike.

Join the Telepresence Activity Group if you haven’t already.   Do both!

David Benham from Cisco on “What is TIP?”

What is this Thumb, Index, Pinky (TIP) thing?

Actually, no, TIP stands for the Telepresence Interoperability Protocol.   But the positional relationship of the one’s thumb, index and pinky fingers makes for a useful analogy to describe one of the key design goals of the TIP protocol.

While there are several standards for robust multimedia conferencing, such SIP, RTP, H.264, H.323, none of have yet dealt with the special challenges of preserving the experience in a conference consisting of many multi-screen endpoints as well as a mix of multi-screen and single-screen endpoints.
In other words, without additional mechanisms, receiving endpoints would only know they received three fingers.  They wouldn’t know how to arrange them in a way that you would recognize as a hand, with the thumb, index and pinky fingers in their proper place on the receiving end.
Preserving those “in-person” positional relationships in a multi-point conference, with other video and audio streams (or other fingers in my analogy) switching in and out quickly from multiple single screen and multi-screen endpoints, is an important goal for any immersive Telepresence system.

TIP does this and a whole bunch more to help enable interoperability between today’s Telepresence systems, but I am going to need some different  analogies to continue.   While I am working on those, please see this informative presentation about TIP.
