本实施规程规定了一种将录像带时间码、胶片边缘编号、制作时间码和其他制作数据编码到符合SMPTE 292M的位序列高清分量电视信号的垂直辅助数据空间的方法。本规程旨在在后期制作中用作传送定义胶片到磁带传输的基本元素的方法。通常情况下，这些信息不会包含在已发布的计划中。尽管参考了SMPTE 292M，但本规范中的任何内容都不排除其在组件数字HDTV信号的并行数字接口中的使用。

This practice specifies a method of encoding video tape time code, film edge numbers, production time code, and other production data into the vertical ancillary data space of a bit-serial high-definition component television signal conforming with SMPTE 292M. This practice is intended for use in post-production as a means of conveying the essential elements that define the film-to-tape transfer. Normally this information is not intended for inclusion in the released program. Despite the reference to SMPTE 292M, nothing in this specification precludes its use in a parallel digital interface for component digital HDTV signals.
