Data stream: NTSC input(standard 720*240) => ADV7282M => MIPI output to IMX6 from NXP. (BT.656-4)
In order to get better image quality, I want to use I2P function at IMX6 instead of doing I2P in ADV7282M, to use I2P function, IMX6 need to know Even/Odd field information, I add a line at Even field by setting 0X7E register. To tell IMX6 about even/odd info.
- To proper configure MIPI CSI2 receiver side at IMX6, below information need to confirm:
- As for BT.656-4, the output would be 720*243(even), 720*244(odd), but considering the input valid data is 720*240(even), 720*240(odd), where will the extra lines be, at the FRAME START, or FRAME END?
- By setting 0X7E additional delay by one line, where will the added line will be? At FRAME START or FRMAE END?
Look forward to getting the answer, thanks in advance!
