Polycom Introduces Open-Standards Based Scalable Video Coding (SVC) Protocol
Today, Polycom introduced the industry’s first open standards-based Scalable Video Coding (SVC) protocol, which Polycom says delivers 3x the previous capacity for HD multipoint video calls for greater scalability, dramatically lower TCO, superior performance and backwards- and forwards-compatibility to protect customer investments.
Last week Polycom announced support for open standards-based SVC, an extension to AVC (Advanced Video Coding H.264), the standard coding protocol used by most of today’s video conferencing devices.
The open standards-based SVC algorithm provides a multi-layered data structure that allows systems to adapt to networks to enhance the resolution, frame rate and quality of video streams, and increase error resiliency, all without requiring excessive bandwidth or administrative intervention. This includes SVC enabling a video stream to be reduced in size automatically if there is a reduction in throughput (e.g., a connectivity bottleneck), allowing the viewer of a video meeting to keep the connection at a slightly lower resolution instead of getting a pause or a video freeze.
By providing native interoperability between the new SVC protocol and standards-based protocols such as AVC, the RealPresence Platform bridges “video islands” caused by earlier, closed implementations of SVC. This interoperability protects customer investments through backwards-compatibility with AVC and other protocols and forwards-compatibility with SVC and future open standards-based protocols that may emerge.
Polycom’s standards-based SVC implementation is built on a framework developed by the Unified Communications Interoperability Forum (UCI Forum), a non-profit network of technology vendors with a shared vision of UC interoperability, and Polycom is licensing its SVC implementation free of charge to the UCI Forum and others to ensure adoption and industry-wide interoperability.
SVC support is available through software updates to components of the RealPresence Platform, including RealPresence Collaboration Server 7.8 and 8.1 (RMX), RealPresence Resource Manager 7.1, and RealPresence® Virtualization Manager 5.1 (DMA). These software updates also include support for Polycom’s next-generation video endpoints also announced today.
