Inter-layer Prediction Algorithm for Spatial Scalability Based on AVS-S

【Abstract】AVS-S standard is a new audio and video standard for video surveillance application. Spatial scalability meets the requirement of changeable resolution bit streams. To improve the coding efficiency, this paper designs tow arithmetics inter-layer prediction for AVS-S based on SVC spatial scalability approach: base layer up-sample re-prediction and inter-layer and inter layer spatio-temporal MV prediction. Simulation result shows that the proposed algorithm is convenient in implementation and excellent in performance.
