Radvision announced plans for the implementation of scalable video coding technology based on H.264 SVC to its SCOPIA conferencing platform during 2009.
SVC 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. The layering capability of scalable coding provides a dramatically higher degree of error resiliency and video quality than can be provided by conventional video coding without a significant increase in bandwidth requirements. Additionally, a single multi-layer SVC video stream can support a broad range of devices and networks.
