本标准规定了由ISO 13818-1 stream_id值标识的MPEG流到MXF通用容器的映射。这包括但不限于ISO 13818-2 MPEG视频流、ISO 11172-2 MPEG视频流、ISO 13818-3 MPEG音频流和ISO 11172-3 MPEG音频流。规定了有无ISO 13818-1 PES层的内容映射。还规定了单流映射和同步多流映射。该文件概述了co的MXF封装的同步要求- 定时MPEG精华流。本标准定义了用于唯一标识特定MPEG实现的SMPTE通用标签。本标准还提供了对单个节目MPEG节目流或传输流多路复用的剪辑包装。本标准不支持多节目MPEG多路复用。本标准未提供对某些传输流数据包已被删除的传输流的支持。本标准不将MPEG-PSI、DVB-SI或ATSC-PSIP映射到任何元数据方案。 为了在任何给定的操作模式中实现互操作性，可能会对该本质容器的实现方式进行限制。建议读者在实施之前仔细研究适当的操作模式文档。

This standard specifies the mapping of MPEG streams, as identified by an ISO 13818-1 stream_id value, into the MXF generic container. This includes, but is not limited to, ISO 13818-2 MPEG video stream, ISO 11172- 2 MPEG video streams, ISO 13818-3 MPEG audio streams, and ISO 11172-3 MPEG audio streams. Provision is made for mapping the content with or without the ISO 13818-1 PES layer. Provision is also made for single stream mapping and synchronized multi-stream mapping. The document outlines synchronization requirements for the MXF encapsulation of co-timed MPEG essence streams. This standard defines SMPTE universal labels to be used to uniquely identify specific MPEG implementations. This standard also provides for clip wrapping a single program MPEG program stream or transport stream multiplex. Support for multi-program MPEG multiplexes is not provided in this standard. Support for transport streams where some of the transport stream packets have been removed is not provided in this standard. This standard does not map MPEG PSI or DVB-SI or ATSC-PSIP to any metadata scheme. In order to achieve interoperability within any given operational pattern, restrictions may be placed on the way in which this essence container can be implemented. The reader is advised to carefully study the appropriate operational pattern document before implementation.
