%X AVS-M is a mobile video standard owned by China. In luminance intra prediction of AVS-M, there are nine modes and two methods for the optimized mode selection-the SAD method and the RDO method, and the choice of optimized mode is very complex. A rapid prediction mode decision algorithm for intra encoding was proposed based on the sorted SAD result. Simulation results show that compared with RDO method, the rapid algorithm can save 30%~40% encoding time with a little performance degradation.
