Abstract: This paper addredsed the video distortion of infra coding in multigeneration, which is introduced by the irreversible operation of current clip module. In order to implement the rcloss free (RLF) infra coding in modified H. 264/AVC,we proposed a novel optimal clipping algorithm based on Integer Linear Programming (ILP). Furthermore, we improved the cost function of infra prediction to guarantee later encoder has the same prediction values with the former.Experimental results show that the ILP-based infra coding method completely eliminates the video degradation and achieves superior performance in comparison with current infra coding method in H. 264.
Key words: Re-loss-free, Multigeneration, Intra coding, ILP, H. 264
