Parallel Implementations of Lambda Domain and R-Lambda Model Rate Control Schemes in a Practical HEVC Encoder

Abstract

This paper summarizes the key parallelization aspects of the two most popular academic rate control (RC) algorithms for High Efficiency Video Coding (HEVC): 1) Lambda domain (LD) [1] and 2) R-Lambda model (R-LM) [2] that were originally designed for the HEVC test model (HM). In this work, these two sequential RC algorithms were ported to the practical Kvazaar open-source HEVC encoder [3] and adapted to work with wavefront parallel processing (WPP) and overlapping wavefront (OWF) parallelization techniques.
