MPEG
MPEG-2压缩编码技术原理应用
MPEG是运动图像专家组(Moving Picture Experts Group)的简称,其实质上的名称为国际标准化组织(ISO)和国际电工委员会(IEC)联合技术委员会(JTC)1的第29 分委员会的第11工作组,即ISO/IEC JTC1/SC29/WG11,成立于1988年。其任务是制定世界通用的视音频编码标准。因为,广播电视数字化所产生的海量数据对存储容量、传输带宽、处理能力及频谱资源利用率提出了不切合实际的要求,使数字化难以实现。为此,该专家组基于帧内图像相邻像素间及相邻行间的空间相关性和相邻帧间运动图像的时间相关性,采用压缩编码技术,将那些对人眼视觉图像和人耳听觉声音不太重要的东西及冗余成分抛弃,从而缩减了存储、传输和处理的数据量,提高了频谱资源利用率,制定了如表1所示的一系列MPEG标准,使数字化正在变为现实。其中,MPEG-2是一组用于视音频压缩编码及其数据流格式的国际标准。它定义了编解码技术及数据流的传输协议;制定了MPEG-2解码器之间的共同标准(MPEG-2编码器之间尚无共同标准)。本文以MPEG-2的系统、MPEG-2的编码、及MPEG-2的应用为题,讨论MPEG-2压缩编码技术。
