Abstract
Roughly described, an input unencoded video stream is first encoded according to a high quality compression standard such as 1080P@60 AVC. The high quality compressed video stream is then transcoded into a scalable format, such as 1080P@60 SVC. Developing the scalable video stream by transcoding offers significant benefits over developing it natively from the original uncompressed picture sequence.
