摘要

H.264/AVC是一种混合预测转换编码器。在本文中，我们提出了一种计算效率更高的方法来实现预测模块，这是其最复杂的阶段。这个想法是采用主流预测模式的一个子集，而不是测试H.264/AVC标准推荐的所有模式。结果表明，对于高清晰度序列，质量损失可以忽略不计，可以控制高清晰度数字电视视频序列的压缩复杂度。

Complexity Reduction Techniques Applied to The Compression of High Definition Sequences in Digital TV

— H.264/AVC is a hybrid predictive-transform coder. In this paper we propose a more computational efﬁcient approach to implement the prediction module, its most complex stage. The idea is to employ a subset of dominant prediction modes instead of testing all modes recommended by H.264/AVC standard. Results show that, for high deﬁnition sequences, the quality loss is negligible allowing us to control the compression complexity of high deﬁnition digital TV video sequences.
