ISO/IEC 13818-2，通常称为MPEG-2视频，包括MPEG-2 4:2:2配置文件的规范。本标准以ISO/IEC 13818-2为基础，为高级别的MPEG-2 4:2:2配置文件提供了附加规范。它旨在用于高清电视制作、贡献和发行应用。与ISO/IEC 13818-2一样，本标准定义了比特流，包括其语法和语义，以及高级别4:2:2配置文件的兼容解码器的要求，但未规定特定的编码器操作参数。

ISO/IEC 13818-2, commonly known as MPEG-2 video, includes specification of the MPEG-2 4:2:2 profile. Based on ISO/IEC 13818-2, this standard provides additional specification for the MPEG-2 4:2:2 profile at high level. It is intended for use in high-definition television production, contribution, and distribution applications. As in ISO/IEC 13818-2, this standard defines bit-streams, including their syntax and semantics, together with the requirements for a compliant decoder for 4:2:2 profile at high level, but does not specify particular encoder operating parameters.
