Tixeo enhances secure videoconferencing interoperability

Olivier AZAN NewsEN

An easier integration with the H.323 / SIP world

Having a powerful and secure videoconferencing service thanks to the Tixeo client software is fine. Granting these services to the H.323 / SIP users is even better.

This is what the TixeoGateway offers in its latest version: it already allowed an H.323 / SIP system to join a Tixeo meeting through an incoming call; Now, a Tixeo user can as well call any legacy videoconferencing system within a single click, making H.323 / SIP outgoing call.

In addition, the H.239 standard is now supported, letting legacy videoconferencing systems to share an application in a Tixeo meeting.

What about security?

Tixeo provides the only technology ensuring end-to-end encryption in a multipoint video meeting, which is simply not possible on H.323 / SIP systems.

Thanks to this new TixeoGateway and its unique architecture, any workstation can call H.323 / SIP room systems or phones without modifying the enterprise’s security policy: network administrators who have once struggled to deploy H.323 / SIP solutions know the nightmare it is and the great amount of open ports it requires. With Tixeo, this difficulty simply does not exist anymore.

Tixeo’s technology offers end-to-end encryption up to the TixeoGateway, which is designed to act as a true security portal between the new Tixeo world and the old H.323 / SIP world, protecting against the security flaws of these old protocols.

Tixeo: secure videoconferencing finally on your Mac

Renaud GHIA NewsEN

Thanks to more than 10 years of experience and innovation in video conferencing, Tixeo introduces a native Mac client empowered with its new encryption architecture. This Mac app offers a real end-to-end encryption for group videoconferencing with Mac or PC.

 Secure video conferencing is a still underestimated issue

Industrial espionage has become a common business practice. Security efforts are often focused on asynchronous tools whereas real-time communications are neglected. Information exchanged during an online meeting is often strategic. Protecting board, business, and technical meetings conducted through video conferencing is not an option!

A new encryption architecture

Tixeo offers an innovative architecture enabling end-to-end encryption for group videoconferencing while maintaining a high adaptability to network fluctuations. This encryption guaranties communications privacy even in the case of an attack targeting the Tixeo server.

This innovation has been made possible by the unique SVC on Demand (Scalable Video Coding on Demand) technology created by Tixeo’s R&D department. Currently constrained by their technological architecture, no other video conferencing vendor can offer such a level of security.

The Tixeo Mac app will allow you to simply organize online meetings from any workstation with an unmatched audio and video quality. During group video conferencing, participants can share their desktop and eventually give control to another participant. More than a videoconferencing tool, with its presence and instant messaging features, Tixeo is a powerful tool for collaboration with your teams.

Secure video conferencing against industrial espionage

Sébastien JEANJEAN NewsEN

Thanks to more than 10 years of experience and innovation in video conferencing, Tixeo empowers its latest version with a new encryption architecture protecting online business meetings against any risk of corporate espionage.

Secure video conferencing is a still underestimated issue

The annual cost of industrial espionage now reaches billions of dollars. Thieves mainly target companies and their innovations but also confidential business information. Stealing strategic information from a competitor has become a common business practice and corporate espionage has become a real industry.

Security of video conferences is currently completely neglected despite the strategic information exchanged during an online meeting. Protecting board, business, and technical meetings conducted through video conferencing is not an option!

No trustworthy offer on the market

After several eavesdropping scandals on the telephone network and Skype, trust in communication tools has been damaged. The governments of some countries require their communications solutions vendors to provide eavesdropping capabilities (backdoors). Thus, this includes over 90% of the solutions on the video conferencing market.

Companies that want to hedge these risks usually isolate the communication tools on a private network. This approach can be efficient for internal communications but has the huge disadvantage of restricting the value of these solutions. In fact, it completely excludes external users: customers, suppliers, and partners.

Tixeo is an innovative answer with a unique encryption architecture for video conferencing.

Fully aware of this issue, in its new version, Tixeo offers a true end-to-end encryption for multipoint video conferencing while maintaining a high adaptability to network fluctuations. In addition to the client-to-server encryption (link encryption), all communications are now encrypted from end to end (from client to client). This end-to-end encryption allows an unparalleled level of security for multipoint communications. Even in the case of an attack targeting the Tixeo server, communications privacy is guaranteed.

EndToEndEncryption

This innovation has been made possible by the unique SVC on Demand (Scalable Video Coding on Demand) technology created last year by Tixeo’s R&D department. Currently constrained by their technological architecture, no other video conferencing vendor can offer such a level of security.

Tixeo innovation: Pushing the limits of multipoint video conferencing

Sébastien JEANJEAN NewsEN

The release of Tixeo v7 comes with a whole new audio and video “stack” with many innovations, including the “SVC on Demand” technology pushing the limits of video conferencing.

“The Holy Grail of video conferencing” smaller video streams for higher quality

To clearly understand the technological step ahead of Tixeo, it is important to have a quick look at the two existing architectures for adaptive multipoint video conferencing:

 

MCU (Multipoint Control Unit): This technology consists in mixing all the video streams received from the participants and send the mixed video stream back to each. It has been used for ages by legacy video conferencing players (Polycom, Cisco, Lifesize…). The H.264 AVC video codec is the most commonly used in these systems.

  • Pros:
    • Each participant only receives one video stream adapted to the network
  • Cons:
    • A high CPU usage (decoding, mixing and re-encoding), often requiring hardware acceleration
    • Low scalability
    • Introduces a delay in communication due to high processing load
    • Quality loss result of the decoding and re-encoding of the video streams

Media relay server: Unlike the MCU, this technology (eg Vidyo) performs no mixing, decoding and re-encoding server side. It is thanks to the properties of the H.264 SVC (Scalable Video Coding) codec that the video streams can be adapted to the receiver’s capacity. Indeed, an SVC video stream contains multiple stacked layers, each representing a different level of quality. Each participant receives as many streams as participants in the meeting and not just one mixed stream with all videos like with an “MCU”.

  • Pros:
    • Low server-side CPU usage (simple video stream filtering)
    • No delay added to communication
    • A good adaptation of video streams to the network capacity
    • Good scalability
    • No loss of quality due to a re-encoding of the video stream
  • Cons:
    • For the same video resolution, an H.264 SVC stream can use up to 20% more bandwidth than an H.264 AVC stream
    • The complexity of H.264 SVC codec induces a higher CPU usage client-side

 

“SVC on Demand”: 10-30% bandwidth saved

Tixeo’s “SVC on Demand” (SVCoD) is a strange creature. It keeps all the advantages of the media relay server architecture, but without the drawbacks. The innovation consists in taking into account the context of the meeting in the encoding strategy. Each client will encode its video stream according to each of the other participants, their network capacity, their equipments and their display resolution.

Indeed, each participant simply sends the video layers needed in a meeting. Tixeo therefore removes any bandwidth overconsumption added by a classic SVC codec.

Consider the case of a call between an HD room, a desktop and a smartphone. With SVCoD, only two video “layers” are used, corresponding to resolutions of the desktop and the smartphone.

The result is simply a higher image quality for a lower bandwidth usage.

 

Max motion

Completely related to its new SVCoD technology, Tixeo introduced “Max motion”, a technology using at all times the maximum frame rate provided by the camera.

Tixeo favors a maximum smoothness, your camera supporting 30 or even 60 frames per second, even in case of network slowdown.

 

New audio stack: Crystal-clear voice in all circumstances

All the studies converge, a good video quality is perceived only if the sound quality is perfect. This is why Tixeo has completely rewritten its audio stack. It now integrates the best audio codec know at this day for communication over the Internet: OPUS. It allows having a lower network usage while significantly increasing the quality, which will remain optimal whatever the type of sound (voice or music) sent.

This new “stack” also contains a more powerful echo canceller, ensuring meetings without any echo whatever the conditions of use.

 

Always highly secured

It is important to remind that the confidentiality of shared information is secured by streams encryption. Tixeo’s solution neither requires opening network ports (HTTPS Tunneling), nor changing the security policy of the company, unlike all known SIP or h.323 solutions.

Tixeo innovation: A dazzling desktop sharing!

Sébastien JEANJEAN NewsEN

Tixeo introduces a new desktop sharing technology in the latest version of its video conferencing and collaboration tool WorkSpace3D, result of several months of internal R&D. The editor says: “The speed and visual quality of sharing have no equivalence among the many tools available today.”

Smooth and responsive in any situation

Anyone with online collaboration needs has already used a desktop sharing tool (VNC, Remote Desktop, TeamViewer, etc.). The main problem encountered when using these tools is often a lack of responsiveness when documents are rich, include animations or videos. This problem is magnified when the Internet connection is a bit too slow.

Tixeo greatly improves the user experience by providing a smooth and high-quality picture never seen before even on mobile 3G connections.

But Tixeo’s solution is a lot more than just a simple desktop sharing tool.

Smart integration with video conferencing

Sharing an application or a desktop is directly done during HD multipoint video conferencing. While communicating in audio and video, participants can share or take control of multiple documents (Excel, Chrome, AutoCAD…). This is made possible by an intelligent network management (proactive QoS) that improves the reliability of communications during a videoconference.

The shared information is also visible from your mobile or tablet, a simple web page or H.323 / SIP video conferencing equipment (Polycom, LifeSize…).

Always highly secured

Tixeo’s solution neither requires opening network ports (HTTPS Tunneling), nor changing the security policy of the company. Confidentiality of shared information is secured by encryption.

The user can choose to share its entire screen or a single window, making all other information confidential (messaging…).

When sharing its desktop, the owner keeps control of his computer, even when allowing another participant to take control remotely.

This sharing technology integrated Tixeo’s video conferencing is one of the most complete, secure and efficient existing today.
