INPUT AND OUTPUT TIMING
Clock and Output Timing
Data Delay (when a standard signal is input)
The data delay is equal to the blank delay. 1H depends on the sampling mode.
The numeric value (T value) may be changed according to a signal state.
Since the output period is fixed during FIFO mode, the amount of delay is changed.
If Y/C separation is performed using TRAP filter during PAL mode, 1H is not added.
