Hi all, I'm now using ADV7441A to recognize the input video(include the resolution and the video interface of HDMI/YPbPr/VGA/CVBS).
I use the one-shot detect mode of STDI to recognize the video interface, but question comes when I read the STDI parameters (FCL/BL/LCVS/LCF/INTLCD) to recognize the resolution. The problem is the INTLCD. According to the HW handbook, when STDI_DVALID=1, all the five parameters is valid. But INTLCD sometimes is error, when input is YPbPr video. And INTLCD will be error especially when in NTSC/PAL of YPbPr Video. How do I to resolve this problem?
