  ABSTRACT: In recent years, rate control is an important technique in real time video communication applications using H.264/AVC. Many existing rate control algorithms employ the quadratic rate-distortion (R-D) model, which is determine the target bits for each I, P, B frame. In this paper, we analysis the problems in rate control for JVT video coding using quadratic R-D model. According to the analysis and experimental results, we present a new frame-layer rate control scheme for JVT video coding based on the quadratic R-D model. Also we estimate the target bit rate for macroblock-layer effectively. The experimental results show that with many scene changes between neighboring frames, existing algorithm exceeded transmission bit rate, while proposed algorithm tranquilized bit rate for stable delivery.
