[ADV7181D] During "coast mode", will input signal on the AIN pin be outputted as video data from the ADV7181D?

Hello,

 

I have a question about "coast mode" of ADV7181D.

 

When a HSYNC is not detected on AIN pin (CVBS input) of ADV7181D, I think it will go into a coast mode.
In coast mode, the ADV7181D will generate its own HSYNC signal and will continue to output video data.

 

In this mode, will the input signal on the AIN pin be outputted as video data from the ADV7181D?
For example, when ADV7181D goes to coast mode from normal operation, and some voltage signal (for example, about 300mV) exists on the AIN pin constantly, then does it appear on the output pins during coast mode?

(Can the constant 300mV signal be seen as gray image on the display during coast mode?)

 

Thank you.
Best regards.
