NOTES
1. Horizontal axis not to scale.
2. A line of digital video extends from the first word of EAV through the last word of video data.
3. The number of samples of video data (sample number ‘ o’ through ‘ p’ in Figure 1) is 2048. That is, the letter ‘ o’ denotes
sample number 0 and the letter ‘ p’ denotes sample number 2047.
4. T is the reference clock period.
5. At the interface, there are variations in the mapping known as “PsF”. See Annex A for a description.

Operational issues
1/HANC/ VANC Metadata gets dropped at many interfaces.
2/ No priority rules, Metadata may be stepped on.
3/ Reclocking is a MUST at every interface point.
