Preliminary Data Sheet
Figure 4-6
Black level correction of luminance signal
The color carrier is removed out of a CVBS signal by means of a notch filter. It is set to
the corresponding color carrier (3.58 or 4.4 MHz) only if the standard is detected
permanently. This prevents the luminance sharpness of being changed within the
standard search process. For Y signals the notch is disabled.
For a fine adjustment of delaycompensation between luminance and chrominance,
YCDEL
allows a luminance shifting in 16 steps of 50ns.
4.6
Decimation
4.6.1
Luminance and chrominance signals are filtered in horizontal and vertical direction. The
coarse horizontal and vertical picture size (1/3, 1/4, 1/6) is independently programmable
with
SIZEHOR
and
SIZEVER
. A fine adjustment in steps of 4 pixel and 2 lines is possible
by
HSHRINK
and
VSHRINK
, which allows correct aspect ratio for multistandard
applications (50/60 Hz mixed mode, (S)VGA).
For main decimation factors, the stored number of pixel and lines are listed in the
following tables.
