Input/Output Delays (at Standard Signal Input)
The illustration below shows the time delay between the input of a video signal and the output of digital data.

Analog Video In
Data output
HSYNC_L output
The data delay, blank delay, and sync signal delay are the same length.
In FIFO mode, the output cycle is fixed, so the delay varies.
The delay value becomes approx. 2.5H only when the adaptive filter (register $10/YC1[6:4] =
“000”) is selected as the Y/C separation filter in PAL mode.
