本标准规定了MXF通用容器（GC）系统项的数据格式，称为 系统方案1。该数据格式是SMPTE 385M（映射）中定义的系统项的超集 SDTI-CP本质和元数据集成到MXF通用容器中），并提供了更通用、更灵活的 可以为灵活的GC包装（包括基于剪辑的包装）提供系统元素的数据结构。这 文件定义了系统项中的系统元素应遵循的规则，以便归类为 系统方案1系统要素。MXF通用容器是材料交换格式（MXF）文件的本机本质容器 身体MXF通用容器是为可流式视听材料的交换而定义的。本文件定义了网络或存储介质信号接口处的数据结构。这 本文档未定义MXF兼容设备的内部存储格式。

This standard specifies the data format for the System Item of the MXF Generic Container (GC) that is called System Scheme 1. This data format is a superset of the System Item defined in SMPTE 385M (Mapping SDTI-CP Essence and Metadata into the MXF Generic Container) and provides a more generic and flexible data structure that can provide system elements for flexible GC wrappings including clip-based wrapping. This document defines the rules that System Elements in the System Item shall follow in order to be classified as a System Scheme 1 System Element.The MXF Generic Container is the native Essence Container of the Material Exchange Format (MXF) File Body. The MXF Generic Container is defined for the interchange of streamable audio-visual material.This document defines the data structure at the signal interfaces of networks or storage media. This document does not define internal storage formats for MXF compliant devices.
