Ancillary Data
You can select which lines in the vertical and horizontal
blanking area are stripped or passed, as well which line
the video image starts on. This allows you to protect and
pass information such as embedded audio, or closed
captioning, with the video signal.

Field and frame line numbers depend on the video format
the switcher is operating in. If the switcher is operating
in a Progressive Scan video format, no even or odd
information is displayed.
Ancillary data parameters are set independently for each
video format. Changing video formats recalls the last
saved parameters for the selected video format.
Tip:
Refer to
on page 37 for
information on setting the ancillary data source for the
MultiViewer outputs.

SMPTE
®
352 Payload Identification
The SMPTE
®
352 payload identifier is inserted into the
ancillary data and carries information to identify such
things as the video format and scanning method, interface
standard, and aspect ratio for the current video signal.
Some upstream devices will insert this information, and
others may not. This can result in the SMPTE
®
352
payload identifier appearing and disappearing as you
transition between video signals, causing problems for
downstream devices such as monitors.
The SMPTE
®
352 payload identifier is inserted after the
passing or stripping of the ancillary data by the switcher.
To Insert the SMPTE
®
352 Payload Identifier

2.
Press
SMPTE 352
to select whether the switcher
inserts the SMPTE
®
352 payload identification (
On
),
or do not insert it (
Off

Setting SMPTE
®
352 to
Off
does not strip the
SMPTE
®
352 payload identifier that was added by
an upstream device.
MultiViewer
The switcher supports both a multi-headed video
processor MultiViewer and a single-headed input
MultiViewer. Both types of MultiViewer generators
allow you to view up to 20 video sources in one of 41
different grids and include mnemonic source names and
red and green tallies on every box.
