SPIRIT DSP has signed its fifth licensing agreement with Polycom. Under terms of the agreement, Polycom has licensed SPIRIT's product to support quality videoconferencing on the Polycom CX5000 Unified Conference Station. As a Polycom-branded version of the Microsoft RoundTable collaboration and conferencing device, the CX5000 system provides engaging group telepresence and also doubles as an analog conference phone.

The Polycom CX5000 Unified Conference Station adds a compelling and engaging group video experience to Microsoft Live Meeting session or to Microsoft Office Communicator conversation. With five cameras and six microphones, the CX5000 is primarily a USB peripheral device that delivers a unique, engaging 360-degree group video experience to Live Meeting 2007 applications, and when used only with Microsoft Office Communication 2007, the client functions as a video switched webcam. It also allows participants who are not within the organization's boundaries or managed video environment, meaning anyone with a PC can download the Live Meeting client and view the meeting. The device has TI C54CST processor inside that powers it, which also runs on SPIRIT communication software.

SPIRIT's engine SDKs are designed for real-time, multipoint, videoconferencing. The software uniquely combines scalable audio with scalable video, a necessary marriage to ensure the highest quality conferencing experience. The voice engine includes highly optimized standard voice codecs, and a patent-free wideband and highly scalable SPIRIT IP-MR voice codec. The video engine includes an H.264 SVC video codec that addresses video packet loss and video quality improvements, including a network adaptation module that compensates for network jitter and packet loss.
