Abstract

A new rate control algorithm based on motion estimation error is presented. The algorithm consists of two steps. The first step deals with the target bit allocation for each frame. The complexity measure which determines the target bit allocation is calculated by using the motion estimation error statistics. The second step is to compute the bit spending profile within a frame. A nonlinear profile based on motion estimation statistics is used to allocate bits for each macroblock more efficiently. Experimental results show that the performance in terms of PSNR is significantly improved over a baseline rate control (TM5) algorithm. Compared to the TM5 baseline algorithm, the new algorithm has very little added complexity because it uses existing information from motion estimation.
