I want to use ADV7181D to convert CVBS to YUV.
ADV7181D is init with recommend settings from <ADV7181D_ADV7181D@_ADV7341-VER.1.0c.txt>.
Then only half width of the input image is captured from the output . And I got 0x49, 0xC0 and 0x2d from status register 1~3.
The input signal is recognized as PAL signal, While it is NTSC actually, and Fsc Lock is 0.
I wonder what does Fsc stands for ? And what would cause auto detection failed?
Hi, Jeyasudha:
Thank you for your reply.
No, I don't have any evaluation board on hand and did't have any try before...
I am debugging our STB which have ADV7181D chip on board.
If I set reg [0x07] = 0x02 to enable auto-detect NTSC only, then I got 0x09 0xc0 0x89 from status regs respectively. The color captured is same with the source in this situation, as the attached picture shows. but other problems is still there...
Best Regards.
