I have read the datasheet. But I still don't know how to use the adv7180. I'm not sure which pin should connect with A33 from all winner. So can you tell me how to use adv7180 ?
A reference schematic is shown in the datasheet on how to connect to the device. I am not sure what the A33 is nor do I know what you are trying to do so it is hard to comment on what you need to do.
If you are interested in analog video decoding you might consider purchasing the ADV7842-7511P low cost evaluation board which comes full software and scripts to work with.

I want to connect a analog camera to A33 by ADV7180. But I'm not sure the process of the ADV7180 how to work. For example when does the mcu A33 know the analog vedio signals have converted?
Once the device is initialized you can check the various sync lock bits in register 0x49. These signal can be routed to the interrupt pin also.
Once the ADV7180 indicates it is locked to the source, the output will be valid.
