Invert Enable Control

Invert Enable
drop down menu appears as follows:
Normal
Pass the audio channel through with no processing.
Invert
Invert the phase of the audio channel.
6.7.1.3.
Input Channel Audio Delay
This control adjusts the audio delay +/- 300.00 ms. This delay is relative to the delay that the module
automatically inserts to match audio path and video path delays.
Note: Negative values are limited to the amount of video delay; the card does not have
negative delay ability. Added Video delay can be applied in the Video tab in order to
achieve a greater negative audio delay. See Section 6.2.1.12
for details on how to add
additional Video delay.

DEINTERLACER TAB
The
Deinterlacer
controls as shown in Figure 6-7 are used to configure parameters associated with the
video de-interlacer. Video de-interlacing is performed so that the scaling/aspect ratio conversion can
occur in the progressive video domain. Scaling/aspect ratio conversion in the progressive domain is the
highest quality way to perform up/down/cross conversion. Sections 6.8.1 to 6.8.1.5 provide detailed
information about each of the menu items.
