SPIRIT adds support for scalable video coding technology

USA: SPIRIT DSP, the world's leading provider of carrier-grade voice and video software engines, has debuted its TeamSpirit 4.0 Conferencing Engine solution with scalable architecture based on H.264 SVC video technology.

TeamSpirit 4.0 Scalable Conferencing Engine is based on the Transcoder Free Operations (TrFO) principle that allows transmitting compressed voice and video without unnecessary signal coding and decoding at the server (MCU) side. That prevents additional server load, significantly lowers the delay and entirely dispose quality degradation typically associated with it.

By transmitting only compressed data, TrFO dramatically lowers overall infrastructure costs: channel capacity can be amplified by up to six times. SPIRIT’s technology allows achieving all those benefits without any increase in traffic volume.

Automatic Rate Selection (ARS) technology used in TeamSpirit 4.0 Scalable Conferencing Engine allows end-users to enjoy the maximum quality allowed by their channel capacity and terminal equipment design.

Thanks to the proprietary solution with limited usage of the interframe correlation, TeamSpirit 4.0 Scalable Conferencing Engine boosts high packet loss robustness and error resiliency even in unmanaged or congested IP-networks, independent of limited client capabilities and provides the best available voice and video quality.

“Scalable approach, used in our new solution, solves most of the existing issues with transmission of real-time, multi-point video and significantly improves user experience with popular video applications, such as conferencing, streaming, broadcasting, surveillance, and others,” said Slava Borilin, VP Products at SPIRIT.

“SPIRIT has developed the world’s first commercial, wideband, scalable voice codec IP-MR™ and now we are leveraging our expertise to keep pace with the most cutting-edge market trends in video, making video quality of PC-based desktop conferencing better than provided by expensive MCUs.

Furthermore, adding H.264 SVC scalable video codec to TeamSpirit 4.0 Scalable Conferencing Engine allows for multi-layer capability which assures the best possible resolution, frame rate and quality of the picture regardless of the type of a terminal, whether it is a mobile phone, a PC or a wide-screen TV.”
