ADV 7391 with BT656-4 NTSC standard

Hello,


I'm working with the ADV 7391 video encoder with an input digital BT656-4 video.
The video standard is NTSC with rectangular pixel (27 MHz clock).

The image size according to BT656-4 standard for NTSC is 720x487 but
it seems like the ADV 7391 doesn't support this type of input.

The supported input is 720x480 which is a bit different from the digital
BT656-4 standard.

I'd be glad to understand what should I do in order to work with the ADV7391
correctly with BT656-4 NTSC standard.

 

Thanks,

Nir
