Description of Functions
• Horizontal aperture compensation
Compensates aperture degradation accompanied by D/A conversion.
This compensation is effective for the following modes; adaptive processing, Y through, and simple comb
modes.
• Switching of Y/C separation modes
The following four modes can be set; however, the adaptive processing mode or Y through mode is normally
used.
(1) Adaptive processing mode
This mode detects interline correlation, switches between comb filter processing and BPF processing,
and operates Y/C separation.
(2) Y through mode
The composite video signal input from ADIN (Pin 1) is A/D converted. It is also D/A converted, and then
output from AYO (Pin 7).
At this time, the output of ACO (Pin 4) is the same output as that of adaptive processing mode.
(3) BPF mode
C signal is generated by passing composite video signal through BPF.
Y output is a signal in which the C signal generated is subtracted from input composite video signal.
(4) Simple comb mode
Y/C separation is operated by the comb filter processing forcibly.
