ST 375:2003 - SMPTE Standard - For Television — Mapping of Vertical Ancillary Data Packets (VANC) into VAUX DIF Blocks of DV-Based 100 Mb/s DIF Stream Format

This standard specifies the mapping of vertical ancillary data packets (VANC) into the payload area of the DV-based 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.
