I am now using ADV7441A as a video decoder (and it will connect to a encoder).
There are 3 input sources connected to ADV7441A. They are:
Unfortunately, when the input cable unplugged from my system, the encoder will stops working anymore. I have already ask for fix about the encoder. But the vender said this problem needs time to fix, or may not be fixed. This causes me a big pain.
As far as I know, when input is selected to CVBS or YPbPr, even the cable is uplugged from ADV7441A, a blue screen will be generated. And this could make the encoder keep working (keep encoding a blue screen).
But I would also like to know does HDMI support this ?
I have read the datasheet and there exists a "HDMI free-run" mode. And the description matches what I want. But after several tries of HDMI register settings, no blue screen comes out when HDMI cable uplugged.
So I would like to know does there exist any recommand register settings for enabling "HDMI free-run" mode of ADV7441A ?
Or any other register settings I could use for solving this problem ?
Please help. Thanks.
