TeamSpirit® 3.2 VideoConferencing Engine
Video conferencing today is transitioning from expensive room-to-room (with dedicated high-end equipment) to
desktop conferencing, available on every PC, IP-phone or mobile device
The demand for integration of video conferencing feature is clear in several market segments:
• in enterprise collaboration solutions video communication is the next logical step in productivity increase
• in Web-conferencing systems, where audio communication is not enough anymore
• in software delivery platforms targeted at carriers, where software based video conferencing can become
another carriers’ over-the-top service, dramatically extending the potential service audience in comparison
with traditional hardware-based service.
Among the factors preventing wide deployment of software video conferencing are high development complexity,
significant infrastructure cost and insufficient visual quality, caused by IP networks impairments, such as delay,
packet loss, etc. Traditional video quality degradation to the quality supported by the terminal of the user with the
poorest connection spoils user-experience, hindering adoption of IP video conferencing.
To address these issues and make high-quality desktop software video conferencing a reality SPIRIT offers its
TeamSpirit® 3.2 VideoConferencing Engine.
Overview Highlights
The VideoConferencing Engine is a powerful software platform to • Up to 8000 voice and 1000 video
integrate video conferencing functionality into enterprise collaboration or conferences participants per server
web-conferencing systems or software delivery platforms. The solution
boosts attractive video quality, high performance and up to 4-10 times • Video quality at least 25% better than
lower infrastructure cost. that of other available software
solutions
The Engine includes all the required media processing functionality along
with SPIRIT’s unique speech and video processing and error resilience • Lowest possible delay for real-time
algorithms. communications
Scalable solution’s architecture allows achieving significant performance
• Scalable media transmission with
breakthrough without quality drawbacks and removes the limitations of proprietary scalable SPIRIT IP-MR™
the “poorest connected user”: the data is sent in chunks depending on the (voice) and H.264 SVC1 (video)
available bandwidth, CPU, packet loss ratio, chosen conference layout codecs
and camera capabilities of every conference participant. • High packet loss robustness
Benefits
