Mode 0 (CCIR–656): Slave Option
(Timing Register 0 TR0 = X X X X X 0 0 0)
The ADV7194 is controlled by the SAV (Start Active Video) and EAV (End Active Video) Time Codes in the Pixel Data. All timing
information is transmitted using a 4-byte synchronization pattern. A synchronization pattern is sent immediately before and after
each line during active picture and retrace. Mode 0 is illustrated in Figure 38. The
HSYNC, VSYNC and BLANK (if not used) pins
should be tied high during this mode. Blank output is available.

Mode 0 (CCIR–656): Master Option
(Timing Register 0 TR0 = X X X X X 0 0 1)
The ADV7194 generates H, V, and F signals required for the SAV (Start Active Video) and EAV (End Active Video) Time Codes in
the CCIR656 standard. The H bit is output on the
HSYNC pin, the V bit is output on the BLANK pin and the F bit is output on
the
VSYNC pin. Mode 0 is illustrated in Figure 39 (NTSC) and Figure 40 (PAL). The H, V, and F transitions relative to the video
waveform are illustrated in Figure 41.
