TIP protocol was developed by Cisco to allow immersive multiscreen interoperability across multi-vendor Telepresence systems. TIP standards describes how to multiplex several video and audio streams and auxiliary-data into RTP flows. TIP supports interoperability across point to point and multipoint Telepresence sessions on multi-screen and single-screen endpoints.
TIP (v6) is supported by a number of currently available Telepresence systems -
- Cisco Telepresence System endpoints v.1.6.5 or later (500, 1100, 1300, 3010, 3200, etc).
- Cisco Telepresence Server v.2.1 or later.
- Polycom UC Intelligent Core Platform to support TIP – Q2 2011

Telepresence Interoperability Protocol for Developers
As part of the acquisition of Tandberg by Cisco, the TIP Protocol was transferred to IMTC to facilitate the distribution of documentation licenses, to host interoperability events and the development of future enhancements to the protocol.
The Telepresence Interoperability Protocol (TIP) and related implementation profile documents were created to help achieve multi-screen interoperability today while industry standards are being developed. The TIP documents are available under a royalty-free protocol implementation license.
Documents are available under a royalty-free protocol implementation license for those who are ready to implement TIP.
They are also available under a 90-day evaluation license for those who want to review the documents before deciding whether to take a protocol implementation license.
The TIP Library open source project was also transferred to IMTC, software which can be used to help speed the integration of TIP into your product or system.
The TIP Library is offered under the Apache 2.0 open source license and IMTC encourages programmers to get involved in making improvements or upgrades to code at Sourceforge.
The TIP (Version 6 and Version 7) specifications are available today. These protocol specifications describe how to multiplex multiple screens, multiple audio streams, and an auxiliary-data screen into respective Real-Time Transport Protocol (RTP) flows using a multiplexing technique.
The TIP protocol specification also defines how RTP Control Protocol (RTCP) based extensions are used to indicate attributes of media flows as they are initiated. It also defines how endpoints and other devices can provide feedback or identify adjustments during the life of the streams.
Both Version 6 and Version 7 of the TIP protocol are available for licensing below.
TIP Implementation Profiles
Company-specific TIP Implementation Profiles explain how options in the TIP protocol are implemented by that company and may include other information that facilitates interoperability. IMTC encourages all companies that bring products to market that use TIP to develop Implementation Profiles documents describing how to achieve interoperability with their systems and to make those publicly available.
Cisco’s TIP Implementation Profiles are available for licensing below.
Licensing of the TIP Protocol and Implementation Profiles
IMTC is licensing the TIP Protocol under a worldwide, royalty-free implementation license. This license applies to any claim in any patent Cisco owns, now or in the future, that is essential for the implementation of the Telepresence Interoperability Protocol (TIP).
Accepting Implementation License Terms
You can accept the terms of the license by accessing the TIP Specification and the related TIP Implementation Profiles below. By downloading a document, you accept the terms of the license to each document. Review the implementation license only before downloading the full documents.
The licenses provide the licensee with a perpetual, worldwide, and royalty-free right to implement TIP or a Profile. The licenses include provisions that suspend the license if a licensee should assert patents it owns that are required to implement TIP or a Profile against another implementer of TIP or a Profile. These provisions are intended to encourage the implementation of TIP.

- Implementation License with TIP v6 spec (PDF – 1.0 MB)
Evaluating TIP Before Taking An Implementation License
IMTC is also making available a 90-day evaluation license for all versions of the TIP Specification. Review the evaluation license only before downloading the full documents.

- Evaluation License with TIP v6 spec (PDF – 1.0 MB)
Licensing of Cisco’S TIP Implementation Profiles
Cisco has licensed its TIP Implementation Profiles to IMTC to make available to any interested party and these are available under both implementation and evaluation licenses below. The Cisco TIP Implementation Profiles explain what options Cisco TelePresence devices can accept among those defined by the TIP Specification and includes other information that will help facilitate interoperability. To contact Cisco to ask technical or further clarification questions, please visit Cisco’s TIP developer web page.
IMTC is sublicensing the Cisco’s TIP Implementation Profiles under a worldwide, royalty-free implementation license. This license applies to any claim in any patent Cisco owns, now or in the future, that is essential for the implementation of Cisco’s Implementation Profiles.

TIP Activity Group at IMTC:
The Telepresence Interoperability Protocol (TIP) AG focuses on improving the interoperability of high-end video conferencing systems that implement TIP.
TIP AG Goals:
- Update the TIP protocol specifications as needed.
- Oversee open source project management
- Facilitate distribution of member’s TIP implementation profiles
- Develop plans for and conduct interoperability testing at IMTC testing events.
- Work with the other IMTC AGs to accomplish the above objectives.
