Abstract—This paper presents an adaptive rate control initialization algorithm for H.264 at low bit rate. First we search the best initialization quantization parameters that used to generate a reconstructed video sequence with highest quality and reconstructed video sequence quality without extremely change of GOP (Group of Pictures) in different characteristic video sequence and different low bit rate. And then we propose a model to express the relationship of bit rate and best initialization quantization parameter. Moreover we use the proposed model to easily determine the best initialization quantization parameter of target bit rate. Compared with two noted algorithms, the measurement result of the objective PSNR and the subjective image quality of the proposed method has the best initialization quantization parameter.

Index Terms—Initialization quantization parameter, rate control, H.264, MAD, DSCQS.
