Based on the researches of rate distortion optimization (RDO) and rate control (RC) techniques for H .264 ,this paper divides the development of RDO and RC into three phases based on RC intention ,namely rate distortion modeling ,considering the effect of quality fluctuation on subjective quality ,subjective distortion guided RC ;analyzes the characteristics of representative RC techniques of each phase ,and focuses on the key and difficult issues of RC needed to be further researched .Then summarizes the RC schemes for transmission oriented error resilient video coding ,scalable video coding (SVC ) and multiple description coding (MDC) as well as stereo and multi-view video coding ,and analyzes further research trends .Finally ,how to develop the RC schemes for high efficiency video coding (HEVC) is discussed .
