BLANK
(Timing Register 0 TR0 = X X X X X 1 0 1)
In this mode the ADV7172/ADV7173 can generate horizontal and vertical SYNC signals. A coincident low transition of both
HSYNC
and
VSYNC
inputs indicates the start of an odd field. A
VSYNC
low transition when
HSYNC
is high indicates the start of
an even field. The
BLANK
signal is optional. When the
BLANK
input is disabled, the ADV7172/ADV7173 automatically blanks all
normally blank lines as per CCIR-624. Mode 2 is illustrated in Figure 30 (NTSC) and Figure 31 (PAL). Figure 32 illustrates the
HSYNC
,
BLANK
and
VSYNC
for an even-to-odd field transition relative to the pixel data. Figure 33 illustrates the
HSYNC
,
BLANK
and
VSYNC
for an odd-to-even field transition relative to the pixel data.
