The latest video encoding standard H.264/AVC achieves excellent encoding performance of at the cost of increased computational complexity and falling encoding speed.In order to overcome poor real-time encoding performance of the important and time consuming motion estimation technology in H.264/AVC standard,aiming at computing redundancy of UMHexagonS algorithm which is selected by H.264/AVC latterly,using marco-block's motion characteristics,formulated the adaptive motion estimation strategies and search points distribution rule.The simulation results show that the proposed motion estimation scheme achieve reduction of about 23% motion estimation encoding time on average compared with UMHexagonS algorithm,in the premise of effectively improving the encoding speed,keep the low bit rate and high quality of encoding advantage for H.264/AVC.
