GUIDE TO INSTALLATION AND OPERATION
12 | DEC-1023
This group allows input selection, operation mode
selection, and selection of the decoding filter. See
figure 3.3.
INPUT FORMAT: Auto, NTSC, PAL, PALm,
SECAM, NTSC B&W, PAL B&W: Select the input
format using the radio buttons.
• When
using AUTO, the DEC-1023 detects
the type of input and automatically switches
to that format by loading the decoder with
the format’s parameters.
• When working with monochrome input
signals, set the format to NTSC B&W or PAL
B&W to accept a black and white input.
OPERATION MODE: Select an option based on
the nature of the input signal:
• STUDIO source type when using high
quality sources
• SATELLITE for satellite sources
• VCR for unstable sources.
DECODING FILTER: Select the decoding filter according to the nature of the input composite signal:
• 2D Adaptive for fast-moving images requiring optimum performance
• Notch/Bandpass for lower-quality sources
• 3D Adaptive for optimum performances with static patterns.
3.5.3 Video Processing
These controls allow the user to adjust some
parameters of the video encoded in the output SDI
signal.
ALL GAIN: -800, -799 …, 799, 800: Sets luma and
chroma gains to a specific value. When other gains
are individually set, ALL GAIN reflects the average
value of the combined gains for a given output
format.
LUMA GAIN: -800, -799 …, 799, 800: Sets luma
gain to a specific value.
CHROMA GAIN: -800, -799 …, 799, 800: Sets
chroma gain to a specific value.
HUE:-40, -39 …, 40: Sets hue to a specific value in
degrees.
BLACK LEVEL: -64, -63 …, 63, 64: In NTSC mode,
sets Black level to a specific value.
