Scalable Video Coding (SVC) is part of the H.264 MPEG-4 Advanced Video Compression (AVC) standard. It automatically adjusts the size of a video stream if there is a reduction in throughput (e.g., a connectivity bottleneck). SVC benefits the viewer by continuing to play at a slightly lower resolution instead of pausing or timing out. SVC helps web conferencing providers offer more reliable video to a broader base of users on a greater range of devices using more practical network bandwidth capabilities.
The WebRTC consortium has mandated support for both SVC and Google’s proprietary counterpart, V8, in the release standard for WebRTC.
