Abstract
Rate control is a capital issue in video coding. It allows a regulation of the bitrate out from the encoder, to cope with some network transmission or quality constraints. Scalable Video Coding emerged several years ago as an answer to the growing need of application-adaptable video streams. Although the interest of scalable video coding has been confirrmed by recent studies, it can not be used in practical contexts without proper rate control techniques. In this paper we present a new rate control scheme for scalable video, based on a simple yet attractive bitrate modelling framework called ρ-domain. Our scheme performs accurate rate control on spatial, temporal and quality scalabilities, while maintaining a constant PSNR. Inter layer prediction is also handled effectively.
