Function Description
1 STD This setting controls standard selection. You can
set this switch for either NTSC or PAL-B.
2 VBI This setting controls vertical blanking. You can
set this switch for either pass or blank. A blank
setting results in blanking lines 10 to 19 and 273
to 282 in NTSC operation and lines 6 to 22 and
319 to 335 in PAL operation.
3 Setup This setting controls setup (pedestal) in NTSC
operation. When the channel is set to PAL
operation, this switch has no effect.
4 Test This setting controls color bars test signal. You
can set this switch so that the color bars test
signal is displayed at the composite output (100/
7.5/75/7.5 for NTSC and 100/0/77/0 for PAL).
This feature requires valid CCIR-601 4:2:2 video
data input.
5 B&W This setting controls black and white output. You
can remove the chrominance and burst from the
channel, thereby creating black and white output.
