Scalable video coding at very low bit rates employing resolution pyramids

In this paper an approach for scalable video coding is described, based on the hybrid coding scheme. The scalability is achieved by decomposing the frames to be coded into a resolution pyramid. Motion estimation and compensation is performed at each level. The focus of the paper is to design motion estimation and compensation such, that the resulting pyramid of vector fields as well as the pyramid of prediction errors can be coded in an efficient fashion.
