本标准规定了基于SMPTE 379-1的许多改进。本标准规定了MXF通用容器（GC）的格式。MXF GC是材料交换格式（MXF）文件体的原生本质容器。MXF GC是为可流化视听材料的交换而定义的。本标准定义了网络或存储介质信号接口处的数据结构。 本标准未定义MXF兼容设备的内部存储格式。相关文档中定义了可以映射到MXF GC中的适当本质和元数据有效载荷。MXF规范包括操作模式规范，这些规范可能会定义对这种基本容器类型的实现方式的限制。 建议读者仔细研究适当的操作模式文档，以符合定义的实现。

This standard specifies numerous refinements based on SMPTE 379-1. This standard specifies the format of the MXF Generic Container (GC). The MXF GC is the native essence container of the material exchange format (MXF) file body. The MXF GC is defined for the interchange of streamable audio-visual material.This standard defines the data structure at the signal interfaces of networks or storage media. This standard does not define internal storage formats for MXF compliant devices.Appropriate essence and metadata payloads that can be mapped into the MXF GC are defined in associated documents.The MXF specification includes operation pattern specifications that may define restrictions on the way in which this essence container type should be implemented. The reader is advised to carefully study the appropriate operational pattern document for compliance to a defined implementation.
