Description
These bits are used to set up the ENCODE mode. The ADV7174/ADV7179 can be set up to
output NTSC, PAL (B/D/G/H/I), and PAL (M and N) standard video.
PAL M is available on the ADV7174 only.
These bits specify which luminance filter is to be selected. The filter selection is made
independent of whether PAL or NTSC is selected.
These bits select the chrominance filter. A low-pass filter can be selected with a choice of
cutoff frequencies 0.65 MHz, 1.0 MHz, 1.3 MHz, or 2 MHz, along with a choice of CIF or QCIF
filters.
