Ancillary Data Setup
The Ancillary Data Menu allows you to select lines in the vertical/horizontal blanking area of the
video stream, which can then be stripped or passed. This menu is useful in situations where you wish
to pass embedded audio or closed captioning.
You can also define the line where the image starts, to prevent any switcher effects (such as keys and
wipes) from modifying lines before the selected line. This protects information such as
closed-captioning, which may reside beyond the normal blanking area.
Refer to the following figure for a visual description of vertical/horizontal blanking (the figure
represents the 480i video format. Field/Frame line numbers will vary depending on the video format
your switcher is operating in.

fields display a single number, representing the frame, when you are running in a progressive video
format. Refer to the section “
Video Formats ” on page 2-12 for more information on interlaced and
progressive video formats.
