SVC (Scalable Video Coding) is an extension to the H.264 codec standard that is used by most of today’s video conferencing devices. SVC video technology allows video conferencing devices to send and receive multi-layered video streams composed of a small base layer and optional additional layers that enhance resolution, frame rate and quality
Layering provides a dramatically higher degree of error resiliency and video quality with no significant need for higher bandwidth. Additionally, a single multi-layer SVC video stream can support a broad a range of devices and networks.

This demo demonstrates how various percentages of packet-loss affects standard H.264 encoded video, compared with RADVISION SVC video.
The Best of Both Worlds
With Scalable Video Coding, RADVISION enables full interoperability with existing devices while enjoying all the benefits of very high network error resiliency and high quality support for room and Telepresence systems. SVC will also improve the quality of connections between cascaded MCUs and allow H.264 Advanced Video Coding (AVC) endpoints to leverage the benefits of SVC.
By applying Scalable Video Coding in an MCU, rather than a gateway approach, RADVISION’s solution enables an evolution rather than revolution to reap the benefits of scalable video in a mixed video coding world. RADVISION’s SVC-enabled desktop and video conferencing infrastructure interoperates with any standards-based endpoint – with no need for dedicated transcoding gateways.
Responding to the market’s need for a single, scalable solution that truly interoperates and handles legacy systems with ease, RADVISION’s SVC approach not only guarantees a high quality experience, but connects with the existing installed base of meeting room equipment, desktops, home offices and high-end telepresence systems.
Along with H.264 SVC, NetSense adapts the bandwidth used to a lower rate before packet loss actually affects call quality through a sophisticated prediction technique. In the event that errors do occur, potentially affecting call quality, SCOPIA V7.5 implements superior error handling through sophisticated Reed-Solomon error correction. When network conditions improve, NetSense restores the call to the original bandwidth utilized. The sum of these capabilities is engineered to provide the best quality experience possible.
