Telepresence is an area poised for growth as it helps companies achieve more productivity and improves communication. Now only if most of us could actually afford telepresence, mainstream adoption will become more common. Cisco has been the leader in the area of high-end telepresence. Recently Cisco announced a personal Cisco® TelePresence system for use in individual offices (list price around $34K) and a large Cisco TelePresence room ideal for group training and cross-functional team meetings. A few upcoming companies are also competing to bring affordable telepresence to desktops using regular broadband, making it attractive to small and medium sized enterprises. Vidyo is one of those and I have seen their product perform quite well on PCs. Google uses it for video chat for GTalk. Vidyo solution is in the range of $10-15K, depending on the setup.
Vidyo Conferencing (see a paper from Frost & Sullivan) takes advantage of the most recent enhancement to the H.264 standard for video compression – Scalable Video Coding (SVC) – resulting in the industry’s best error resiliency enabling reliable HD video communication over the public Internet. The VidyoRouter™ architecture eliminates the expensive, performance degrading, transcoding MCU found in legacy systems, and instead provides high quality, natural communication experiences with PSTN equivalent latency.
H.264 SVC standards are still evolving. Where there is agreement on coding/decoding, the actual transmission of H.264 SVC frames is still under development within the ITU. Video conferencing vendors including Radvision and Vidyo (and their partners) have already introduced H.264 SVC solutions, but until final standards are established, interoperability among different H.264 SVC solutions isn’t possible
