Television - Mapping of Vertical Ancillary Data Packets and Extended Video Line Data into Video DIF Blocks of DV-Based 50 Mb/s DIF Stream Format 电视.垂直辅助数据包和扩展视频线数据到基于DV的50MB/s DIF流格式的视频DIF块的映射

发布日期： 2003-01-01

本标准旨在规定将串行数字接口（SDI）的垂直消隐间隔（VBI）空间中的扩展视频线数据和垂直辅助数据包（VANC）映射为SMPTE 314M中定义的50 Mb/s数字接口格式（DIF）结构。VANC数据包的格式在SMPTE 291M中定义。扩展视频线数据的映射允许在525系统中增加7.5行的视频光圈，在625系统中增加9行的光圈。VANC数据包的映射通过基于50 Mb/s DV的DIF流结构提供元数据和数据本质的传输。

The purpose of this standard is to specify mapping of the extended video line data and the vertical ancillary data packets (VANC) present in the vertical blanking interval (VBI) space of the serial digital interface (SDI) into a 50 Mb/s digital interface format (DIF) structure defined in SMPTE 314M. Format of a VANC packet is defined in SMPTE 291M. Mapping of the extended video line data permits an increase of video aperture of 7.5 lines in the 525 system and an aperture increase of 9 lines in the 625 system. Mapping of VANC packets provides for carriage of metadata and data essence through the 50 Mb/s DV-based DIF stream structure.
