本标准规定了符合SMPTE 326M的本质和元数据到MXF通用容器的映射。MXF通用容器是在MXF文件体中使用的本机essence容器。本标准将SDTI-CP兼容系统项指定为 MXF通用容器。然后，本标准描述了SDTI-CP系统项如何符合SMPTE ST 326，可映射到MXF通用容器的SDTI-CP兼容系统项中 通过SMPTE ST 379-1和SMPTE ST 379-2。本标准还规定了SDTI-CP图像、声音和辅助项目如何符合SMPTE ST 326的要求 可以映射到MXF通用容器中。这包括SDTI-CP元素的映射符合 SMPTE ST 326。如果需要，本标准还定义了MXF通用容器如何包含适当的 元数据和精华元素可以映射到SMPTE ST 326。

This standard specifies the mapping of essence and metadata conforming to SMPTE 326M to the MXF generic container. The MXF generic container is the native essence container for use in an MXF file body.This standard specifies an SDTI-CP compatible System Item as a sequence of metadata elements in the MXF Generic Container. The standard then describes how the SDTI-CP System Item, conforming to SMPTE ST 326, can be mapped into the SDTI-CP compatible System Item of the MXF Generic Container as defined by both SMPTE ST 379-1 and SMPTE ST 379-2.This standard also specifies how SDTI-CP picture, sound and Auxiliary Items conforming to SMPTE ST 326 can be mapped into the MXF Generic Container. This includes mapping of SDTI-CP elements conforming to SMPTE ST 326.Where required, this standard also defines how the MXF Generic Container containing the appropriate metadata and Essence Elements can be mapped into SMPTE ST 326.
