erator 75% Color Bars test signal to the channel output.
Note

ative sync and burst may be offset in relation to the input SDI stream timing.
•
EDH Insertion – insertion of new EDH can be enabled or disabled
(input EDH is always removed).
•
HANC – horizontal ancillary data (including embedded audio) may be
passed or blanked.
