本标准规定了垂直辅助数据包（VANC）到SMPTE 370M中定义的基于DV的100 Mb/s数字接口格式（DIF）结构VAUX DIF块的有效负载区域的映射。元数据和数据本质可能包含在VANC数据包中，VANC数据包存在于未压缩的高清串行数字接口（HD-SDI）的垂直消隐间隔（VBI）中。本标准的目的是定义如何将此类数据映射到基于100 Mb/s DV的压缩信号流格式的视频辅助（VAUX）DIF块。此映射适用于HD-SDI上的1080/60i、1080/50i和720/60p信号格式。本标准规定了垂直辅助数据包（VANC）到DV有效负载区域的映射- 基于SMPTE 370M中定义的100 Mb/s数字接口格式（DIF）结构VAUX DIF块。元数据和数据本质可能包含在VANC数据包中，VANC数据包存在于未压缩的高清串行数字接口（HD-SDI）的垂直消隐间隔（VBI）中。本标准的目的是定义如何将此类数据映射到基于100 Mb/s DV的压缩信号流格式的视频辅助（VAUX）DIF块。此映射适用于HD-SDI上的1080/60I、1080/50I和720/60p信号格式。

This standard specifies the mapping of vertical ancillary data packets (VANC) into the payload area of the DVbased 100 Mb/s digital interface format (DIF) structure VAUX DIF blocks as defined in SMPTE 370M. Metadata and data essence may be contained in VANC packets present in vertical blanking interval (VBI) of the uncompressed high-definition serial digital interface (HD-SDI). The purpose of this standard is to define how such data is mapped into the video auxiliary (VAUX) DIF blocks of the 100 Mb/s DV-based compressed signal stream format. This mapping is applicable to the 1080/60i, 1080/50i, and 720/60p signal formats present on the HD-SDI.
