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.

HSYNC_L output
The data delay, blank delay, and sync signal delay are the same length.
1H varies with the sampling mode.
Depending on the signal status, the numeric value (T value) may vary.
In the FIFO mode, the output cycle is fixed, so the delay varies.
In the PAL mode, where Y/C separation is performed by trap filter, 1H is not added.
