All Lines – Composite In Video Path Processing
The incoming video composite signal path for each channel can be pro-
cessed before decoding. These processing functions affect all lines of video
at once, both active picture lines and VBI lines.
The following processing functions are available for the video composite
input signals:
•
AGC and ACC on or off – the Auto Gain Control (AGC) and Auto
Chroma Control (ACC) are set to default to the off condition (
Enable AGC
and
ACC
checkboxes not checked). This is the recommended state and
provides the following controls for video and chroma gain:
•
Input Video Gain – adjust the input video gain in percent relative to
100% (100% = 1 V p-p). AGC operation is based on sync tip.
