Change:
Click the Change button to open the
Select AFD
panel showing the available AFD codes that could be
used as the default. Click on one to select it, then click
Apply
or
OK
at the bottom of the panel.
Keep Last:
click in this checkbox to use the last detected
AFD code at the input as the default code to be used in
the
Auto
mode when no AFD flag is detected. This box is
disabled in the
Forced
mode.
5.5.5.2 Config section
Incoming –
the three types of AFD are shown, with a
presence icon for each, and a pulldown to establish the
priority of each type. The priorities are reset with each
new selection; e.g. if AFD is 1 and VLI is 2, and you use
the pulldown to choose VLI priority as 1, then AFD will be
bumped down to 2.
•
Ignore a specific flag completely by selecting “Don’t
use” as its priority level.
The available types depend on the input format – AFD
only for HD inputs; AFD and VLI for SD-59.94 Hz inputs,
and all three types for SD-50 Hz inputs.
The set priority is used only during input AFD AUTO
mode. The XVP-3901 will examine the incoming data in
the selected order of priority in order to extract the AFD data. If, in AUTO mode, an AFD flag is set to priority 1 and is
missing at the input, the XVP-3901 will use the incoming AFD flag set to the next priority level.
The
Detected
box shows the AFD code detected.
Outgoing – o
n the SD output, the AFD code shown in the
Inserted
box will be inserted in up to three different formats
simultaneously. Supported formats are shown; select their respective checkboxes to enable insertion. AFD will be
inserted in the line selected in the
Insertion Line
pulldown. Note that VLI is normally inserted on line 14, so if AFD is
placed on line 14 using the pulldown, VLI will not be inserted.
Field Extract AFD & VLI
– Select the field from which AFD and VLI will be extracted:
•
Field 1
•
Field 2
•
Field 1 & 2
Note that this selection applies to both SD and HD outputs, and can also be set from the equivalent panel in the HD
Output section (see page 40).
Alternate ARC section
When the output is 4:3 SD, if the input AFD setting is set to Auto or Forced mode and the input AFD is a full screen
16:9 (AFD code 16:9_2 or 16:9_8), the output image may be scaled in one of 2 ways. Use the pulldown to select
which will be used:
•
Letterbox:
Uses the traditional 16:9 letter box within a 4:3 frame where there is no loss of image.
•
Center Cut:
The XVP-3901 provides a second alternative – the input is horizontally cropped about the center to
create a full screen 4:3 image. Choosing this alternative essentially removes 25% of the original image.
