Abstract:

An efficient rate-distortion (RD) optimized macroblock mode decision algorithm for H.264-Scalable video coding (SVC) extension in packet loss environment is presented. The end-to-end distortion is estimated according to the hierarchy B picture coding structure of SVC and the error-propagated distortion stored in a distortion map. A parameter on temporal level is added to the RD optimized macroblock mode decision algorithm in current H.264-SVC test model to improve the error resilience performance of the encoded scalable streams. The simulation results show that the proposed method outperforms the RD optimized macroblock mode decision algorithm in current H.264-SVC test model.
