摘要
针对H.264解码器的参考模型JM对CAVLC算法的查表部分进行分析,并提出了改进的算法。其中提出了三种改进的算法,分别为分组子表法、二叉树法和二叉树子表混合法。通过上述三种方法的优化,使查表过程中可以避免对这个码表进行查找,节省了查表时间,提高了查表速度。
H. 264 decoder＇s reference JM model analyzes some of the lookup table of CAVLC, and puts forward an improved algorithm, three improved algorithm are proposed, namely sub- division table, tree and tree- hybrid form. Through all these three methods of optimization,the code table can be avoided to look up in process of lookup table,time is saved and the speed is improved, real - time decoding is also improved.
