Output
This function allows the following selections to be
made to the output setup:
Mode
This controls the way the output signalling is
selected.
Follow The output line 23 and VI data will be
determined automatically by the ARC130S
based on either the preset aspect ratio
conversion selected, the user memory in
use or, the incoming AUTO aspect ratio
control signal.
Forced The ARC130S does not use the stored
values but uses the values visible on the
menus (see below).
Line 23 Set
This is a setup menu for the Line 23 output
Type
This sets the type of output-line 23. Selections are
either
ETSI
or
AFD
Output On/Off
This option has a toggle action. It determines
whether or not Line 23 signalling will be present on
the output of the ARC 130S .
User Pass
If PASS is selected then the user bits are copied
from an incoming enhanced line 23 signal to the
output if the enhanced line 23 signal has been
selected as the source of automatic aspect ratio
control.
User Set
This allows the user to set the four enhanced line
23 output user bits to the value shown.
Alt Out
This allows the user to turn on and off an
alternative line 23 widescreen signalling output.
This alternative line 23 output can be placed on a
different line to the normal line 23 widescreen
signalling output. This is useful when equipment
downstream of the ARC strictly enforces blanking
of the first half of line 23 but, can pass other
vertical interval lines.
Note that the alternative line 23 output will only
work if the normal line 23 output is turned on. If the
normal line 23 output is turned off, the alternative
line 23 output will also be turned off.
Alt Line
This controls on which output video line the line 23
style widescreen signalling will appear. Selecting
this menu item displays the output line number that
can be adjusted in the range 7 to 23. The default
value is 23.
