====== Scalable Video Coding ====== Drift occurs when one truncates a video stream to accommodate a lower bandwidth. Quality losses accumulate from frame to frame and eventually become unacceptable. Traditional scalable encoder provide poor rate-distortion performance because they attempt to completely eliminate drift. We created a video encoder architecture that instead aims at keeping drift under control. This encoder produces video streams that can be truncated to accommodate various bandwidths with rate-distortion performance with minimal loss of quality * The decoder. {{ twoloopd.png }} * The encoder. {{ twoloope.png }} ===== Collaborators ===== * [[http://www.informatik.uni-trier.de/~ley/db/indices/a-tree/r/Reibman:Amy_R=.html|Amy Reibman]] * [[http://www.informatik.uni-trier.de/~ley/db/indices/a-tree/b/Basso:Andrea.html|Andrea Basso]] ===== Publications ===== Amy R.
