Stop the blank output from the composite video decoder IC ADV7182WBCPZ

Hi,

 

I'm using ADV7182WBCPZ IC for composite video input in my design. I've connected the output of the decoder to FPGA.

I have provided a LED to check the data availability at FPGA. 

Now, if my FPGA wants to detect the data input availability at the input of the ADV7182WBCPZ IC its not able to detect properly (LED is on at all times) since the ADV7182WBCPZ device is sending a continuous test pattern.

So is it possible to stop the device sending a test pattern when there is no data available to it ?

 

Thanks in advance,

Nanjunda
