ARC130S SECTION

ARC130S 060801 Version 1 Issue 1
4.9
AUTO
This allows the user to control the action of the
ARC130S in the presence of an incoming Line 23
aspect ratio or video index signal. From the Home
Screen, press ENT and scroll to Auto.
Input
This function allows the following selections to be
made to the input setup:
Source
This allows the source of automatic aspect ratio
control to be selected from the following:
L23 ETSI
L23 AFD
Video Ind
L23 Blk
This sets the blanking action applied to line 23.
There are three options.
Auto
The machine will either automatically
provide the appropriate output
signalling blanking using the input
signalling
Not Blk
The input signalling will not be blanked
.5
Line
The first half line of the line 23
signalling will be blanked
L23 WFM
This gives you a choice of Normal or Non-Std.
Normal should be selected for all legal incoming
line 23 signals.
Non-Std should be selected for incoming line 23
sources where there is no blanking period between
the line 23 signalling and the following video.
L23 Line
This controls which input video line the incoming
line 23 style widescreen signalling will appear.
This is useful when equipment up-stream of the
ARC strictly enforces blanking of the first half of
line 23 but, can pass other vertical interval lines.
Selecting this menu item displays the input line
number that can be adjusted in the range 7 to 23.
The default value is 23.
L23 Loss
This reveals a menu that gives a choice of No
Mem or Mem 12
This controls what happens when the ARC is in
auto mode, and the incoming line 23 signal
disappears. If No Mem is selected then the ARC
stays exactly as it is until a valid line 23 signal
reappears. If Mem 12 is selected then the ARC
recalls User Display memory 12 when the line 23
input disappears
VI Type
This selects what type of video index signal is
being applied to the ARC input.
Either AFD Spec or SMPTE (186) may be
selected. If SMPTE186 is selected only the bottom
3 bits of the VI data are examined.
AFD IN
This selects the type of AFD information derived
from the input.
AFD & SS
All AFD and scanning system data
AFD
Active region descriptor data only
