本规程描述了将SMPTE元数据和其他数据本质（在SMPTE KLV协议中编码）映射到MPEG-2系统流的方法。使用同步流及其语法和语义超出了本实践的范围。

This practice describes a means for mapping SMPTE metadata and other data essence, encoded in the SMPTE KLV protocol, into MPEG-2 system streams. Use of synchronized streams and their syntax and semantics is beyond the scope of this practice.
