ADV7393 - Video Output after hard reset

Hello.

Needed a clarification on the video output of the ADV7393 after a hard reset. Data sheet mentions that it will default to SD mode after reset.

If I have a BT.656 signal being provided as the input to the ADV7393, will it generate a valid video signal even if it has not been initialized?

 

Background of my setup:

I have a FPGA providing the BT.656 video signal to the ADV7393. An external MCU is used to configure the ADV via I2C. The MCU takes about 3 seconds to boot up and initialize the 7393 during which time, I am seeing some junk on the video output. I am trying to figure out if this can be avoided.
