Abstract :
Lossy video coding can be achieved by using the H.264 Advanced Video Coding. Some methods have been proposed to transform this coder into a lossless one. The hierarchical lossless video coding structure with new intra algorithm prediction was proposed to reach this goal. In this paper we proposed some enhancements of this method to improve the coding efficiency. The simulation results show that the proposed enhancements reduce the total bit of the coded sequence and the execution time.
