In this mode the ADV7175/ADV7176 accepts horizontal SYNC and Odd/Even FIELD signals. A transition of the FIELD input
when
HSYNC
is low indicates a new frame, i.e., vertical retrace. T he
BLANK
signal is optional. When the
BLANK
input is disabled
the ADV7175/ADV7176 automatically blanks all normally blank lines as per CCIR-624. Mode 1 is illustrated in Figure 17 (NT SC)
and Figure 18 (PAL).
