Mode 2: Master Option
HSYNC, VSYNC, BLANK
(Timing Register 0 TR0 = X X X X X 1 0 1)
In this mode the ADV7194 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 ADV7194 automatically blanks all normally blank lines as
per CCIR-624. Mode 2 is illustrated in Figure 45 (NTSC) and Figure 46 (PAL). Figure 47 illustrates the
HSYNC, BLANK and
VSYNC for an even-to-odd eld transition relative to the pixel data. Figure 48 illustrates the HSYNC, BLANK and VSYNC for
an odd-to-even eld transition relative to the pixel data.
