H.264解码器中CAVLC码表查找算法的改进

Improvement on CAVLC Codebook Lookup Algorithm in H.264 Decoder

针对H.264解码器参考模型JM6.1提出了一种CAVLC码表查找算法的改进方法。通过将二维码表转换成二叉树形式,避免了对整个码表的遍历查找过程,使查找速度提高了2～3倍。

This paper proposes an i mproved CAVLC2-D codebook lookup method for H.264decoder reference softwar e JM6.1.By using binary tree instead of2-D table,the new method can avoid of traversing in whole table to find a matched code,and can speedup lookup pro cess2～3times.
