8964DEC/-FS Instruction Manual 15
Configuration
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.
Note Manually adjusting Input Video Gain may shift picture position slightly
(± 1 clock).
• Input Chroma Gain – adjust the percentage of chroma gain relative
to 100%.
Checking the Enable AGC or Enable ACC checkbox will enable the
respective automatic gain settings.
• Monochrome In – check this box when a monochrome input signal (or
any signal that does not contain burst) is being fed to a channel. This
chechbox must be checked for the module to recognize the signal as
valid and light the corresponding input LED. This will also enable the
Chroma Kill function on the Video Proc page, changing it to a read-only
state.
Active Picture Lines – Video Path Processing
The video processing functions described below affect all active picture
lines (F_Active lines and the P_Active the user has chosen to be part of the
active picture).
The available video path processing controls are the following:
• Contrast/Y Gain – adjusts the percentage of luminance relative to
white.
• Saturation/Chroma Gain – adjusts percentage of saturation and
chroma gain relative to 100% saturation.
• Brightness/Y Offset – adjusts amount of brightness/Y offset in mV.
• Hue/Chroma Phase – adjusts hue/chroma phase in degrees for both
line rates (525 and 625).
• Remove Setup – set to NO when no setup is present (Japanese NTSC), or
YES when setup is present (NTSC). Available in 525 mode only.
• TSG (100% Color Bars) – when on, enables the internal test signal gen-
erator to output a 100% Color Bars test signal to the channel output.
• TSG (Pathological) – when on, enables the internal test signal generator
to output a Pathological test signal to the channel output.
Note Test signals are not adjustable in the Video Processing controls.
