functions implemented. If no AFD flag is detected at the input, the card uses the Default AFD flag specified in the
AFD tab
Note 2 – Forced mode:
Forced mode is useful when the input AFD flag is unreliable, missing or if the user wants a
simple way to force the aspect ratio conversion. The function is the same as the Auto mode, except that the
incoming AFD flag is ignored, and a user-specified forced flag is used instead. As in the Auto mode, the ARC
controls and presets described below are
disabled
.
The input screen shows how much of the input signal will appear at the output after the ARC processing in the XVP-
3901. It does so by showing any cropped portions of the image in blue.
The Output Screen
The output screen shows the final result of the ARC processing.
•
The side panels or letterbox is shown in the selected background color
•
The masks are shown in Gray
3G/HD output – A pull-down menu at the bottom of the screen allows the user to select the output format:
•
1920x1080p – Level A (mapping 1), 1920x1080p – Level B, 1920x1080i or 1280x720p, with the frame rate
matching the input.
SD output – a pulldown at the top of the screen allows the user to select the output aspect ratio
•
4:3 or 16:9
5.4.1 ARC tab
Under the ARC (Aspect Ratio Conversion) tab, several sub-
sections are found allowing extended control over how the
output will be displayed. For convenience, ARC presets are
available for frequently-encountered aspect ratio
conversions.
•
These controls are disabled when the ARC Mode
pulldown on the Input Screen is set to
Auto
or
Forced
You can configure the ARC parameters differently for an SD
input than for a 3G/HD input. The card will remember the
different parameters and will load them automatically without
user intervention based on whether the video input is SD or
3G/HD. Ensure the card has a video signal of the desired
format before changing the configuration.
When using manual aspect ratio mode (AFD mode is 4:3 or
16:9), the card will remember automatically all the
parameters for the different combinations of input/output
aspect ratio conversions (see the combinations below). This means you can configure the card once for each type of
conversion and then the card will restore the configuration automatically when the proper input format and
input/output aspect ratio is encountered.

SD 4:3 to 3G/HD 16:9
•
SD 16:9 to 3G/HD 16:9
•
3G/HD 16:9 to 3G/HD 16:9
