1.2.8.2.6.4 Embedded Sync Ancillary Data
With Embedded Sync streams, only Vertical Ancillary Data can be extracted. The Vertical Ancillary Data
buffer is the same width as the corresponding Luma and Chroma buffers. The channel from which Vertical
Ancillary Data is extracted is a configuration option.
Horizontal Ancillary data cannot be extracted using embedded sync mode.
The Vertical Ancillary Data is captured starting from the end of the previous active video. See
for a more detailed description of embedded sync packing.
