iMX6Q＋ADV7180: the picture will move up and down when switch TV standard of input between PAL and NTSC

[adamzhu]

My board is VAB820 (VIA), which based on imx6q , and connect adv7180 to realize parallel capture function. But when I switch the TV mode of input between PAL and NTSC , the picture will move up and down. Is there any solution to fix the problem? Thanks!!

Hi Adam

seems this is expected behaviour as with switching mode synchronization

will be lost and some time is needed to recover it.

Best regards

it is moving up and down due to lost synchronization.
