About video input interface

Hi everyone, I am currently having one customized carrier board designed for TX2, our client has one requirement that if tx2 can have analog / digital video input interface such as SDI or HDMI so that the video signal can be directly given to the module and do some analysis. Does anyone know the solution that? Thanks.

You can use SDI to PCIE or HDMI to PCIE board.
