Telepresence Interoperability Protocol for Developers

IMTC is pleased to be supporting the TIP protocol for the industry. As part of the acquisition of Tandberg by Cisco, the TIP Protocol was transferred to IMTC to facilitate the distribution of TIP Protocol documentation licenses as well as 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 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 IMTC has also formed the Telepresence Interoperability Protocol (TIP) Activity Group (AG) to update the TIP protocol specifications as needed, oversee open source project management, facilitate distribution of member’s TIP implementation profiles, and develop plans for and conduct interoperability testing at IMTC testing events.

TIP Documentation

TIP Specification

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.

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.

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.

IMTC is also making the Cisco’s TIP Implementation Profiles available under a 90-day Evaluation License.
