The set priority is used only during 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 HD output, the AFD code shown in the
Inserted
box will be inserted in the line selected in the
Insertion Line
pulldown, as an Ancillary Aspect Ratio packet (SMPTE 2016). Deselect the AFD checkbox to inhibit
insertion. Note that VLI and WSS flags cannot be inserted on HD-SDI signals.
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 HD and SD outputs, and can also be set from the equivalent panel in the SD
Output section (see page 57).
5.4.6 3G/HD Output – De-interlacer tab
Some interlaced video sources are film-based originating
from 24p film images. For optimum scaling performance, it
would be best to de-interlace this type of source by simply
merging the source’s fields to recreate the original 24p image,
thereby introducing no de-interlacing artifacts prior to scaling
and format conversion.
Film mode:
When The Film Mode selection is set to ON, the
XVP-3901 monitors the input for film-based sequences and
applies the proper algorithm.
Film detection is provided for 3:2, 2:2 (59Hz and 50 Hz sources) and 5:5 sequences.
Video Over Film:
When the film mode is enabled, turn ON the Video-Over-Film (VOF) function to detect and bypass
field-merging on certain video regions such as scrolling video characters over an entire film frame, thereby preventing
any unwanted combing effects.
There is only one de-interlacer on the card. Any changes made within this tab will be copied over to the De-interlacer
tab in the Video Output (SD) panel.
5.5 Video Outputs panel – SD Output tab
This panel allows control over several aspects of the standard definition video output:
•
aspect ratio conversion
•
timing control
•
image quality processing
•
metadata insertion.
