Mode 0 (CCIR–656): Slave Option
(Timing Register 0 TR0 = X X X X X 0 0 0)
The ADV7172/ADV7173 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 23. The
HSYNC
, FIELD/
VSYNC
and
BLANK
(if not used) pins should be tied high during this mode.
