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.
