5.5.6 SD 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-interlacer 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 – 3G/HD panel.
5.6 Audio Processing panel
The Audio Processing panel provides full audio processing
and delay parameters for up to 32 channels. The first 16
channels come from the embedded input channels and/or the
discrete AES inputs. The second set of 16 channels comes
from the output channels of the following modules:
•
Dolby E/Digital (AC-3) decoder module(s)
•
Linear Acoustic’s upMAX
tm
module(s)
•
Downmix
The 32 processed audio channels can be assigned later to
the Dolby-E/Digital encoder modules, the 3G/HD output
embedder, the SD output embedder, the discrete AES
outputs, or sent to one or two DAP or UAP
companion cards
using the A-BUS. To enable the “Audio Processing”
functionality, you must either have enabled the audio option
or you must have an external audio card connected through
the ABUS.
You can configure the audio processor 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.
Group Detected
section
Status indicators turn green when audio groups 1, 2, 3 or 4 are detected in the incoming signal. The Group Detected
warning color can be configured by the user in the Alarm Config panel (Sect. 5.20)
