# 视频编码的国际标准概述

* 视频编码国际标准是由来自国际标准化组织(*ISO*)及国际电信联盟(*ITU*)等组织的专家委员会共同制定的。其目的是制定一套行业内通用的视频格式，来实现不同厂商、不同视频编码相关软硬件制造商之间的互通。
* 视频编码算法标准化，是从图像压缩方案开始的，例如应用于传真等应用中的二值图像压缩标准JBIG(*ITU-T Rec. T82 and ISO/IEC 11544, March 1993*），以及可用于彩色图像的普通图像压缩标准JPEG(*ITU-T Rec. T81 and ISO/IEC 10918-1*)。JPEG标准化开始于1986年，但是该标准直到1992年才被ITU-T批准，1994年被ISO批准。19世纪80年代开始的一项重要的视频压缩算法标准化，ITU-T H.261，1988年被批准，是视觉通信领域第一个里程碑式的标准。在此基础上，随着电视、电影、计算机、通信、信号处理领域的发展，以及各厂商新的使用要求提出，视频标准化活动得到了极大的促进。随后产出了MPEG-1，H.263，MPEG-2，MPEG-4第二部分，AVC/H.264，以及HEVC/H.265算法。在接下来的章节中，我们将简要介绍图像及视频编码相关的几个主要国际标准。
