一个新声音和中国的图象压缩标准,已知的同样先进的 AudioVideo 编码标准(AVS ) ,正在出现。这个标准等等在象数字广播、高密度的 laser-digitalstorage 媒介那样的信息工业以内为许多应用程序提供一个技术答案。AVS, AVS1-P2,目标标准定义(SD ) 和高定义(HD ) 格式图象压缩的基本部分,和目的到与更低的计算复杂性作为 H.264/AVCbut 完成类似的 coding 效率。在这篇论文,我们简短首先在 AVS1-P2 描述主要编码工具,然后执行在 AVS1-P2 Jizhun 侧面和 H.264/AVC main 侧面之间的编码效率比较。AVS1-P2 Jizhun 介绍的试验性的结果表演以节省 onHD 的小点率相对 H.264/AVC 主要侧面有 2.96% 效率损失的一般水准 28.52% 的进步扫描的序列,和一般水准在交错, 交替, 交叉, 隔行扫描扫描序列上编码损失。不过, AVS1-P2 拥有更低的计算复杂性的一个珍贵特征。
A new audio and video compression standard of China,known as advanced Audio Video coding Standard (AVS).is emerging.This standard provides a technical solution for many applications within the information industry such as digital broadcast,high-density laser—digital storage media,and so on.The basic part of AVS,AVS1-P2,targets standard definition (SD)and high definition(HD)format video compression,and aims to achieve similar coding efficiency as H.264/AVC but with lower computational complexity.In this paper,we first briefly describe the major coding tools in AVS1-P2,and then perform the coding efficiency comparison between AVS1-P2 Jizhun profile and H.264/AVC main profile.The experimental results show that the AVS1-P2 Jizhun profile has an average of 2.96% efficiency loss relative to H.264/AVC main profile in terms of bit-rate saving on HD progressive-scan sequences,and an average of 28.52% coding loss on interlace-scan sequences.Nevertheless,AVS1-P2 possesses a valuable feature of lower computational complexity.
