What do you mean by a pixel interceptor?

Can you provide a more detailed description of what you are trying to find?

Hi Chris

   I have LVDS signals coming through into the FPGA (from the Toradex iMX6) and I am now just passing it (no intercepting whatsoever for now) to the LCD screen. What I am trying to do is to have the FPGA overlay a new image onto the existing LVDS signals and then display to the LCD screen. I would appreciate if you could give me ideas on how to do that.

Hi @vivienwwp,

 

LVDS is a voltage standard and can be used for many applications.

What video standard/format is being used to send video to the LCD screen? 

 

To overlay a new image, you will need to have an IP that is able to understand your video stream format before any overlay can be completed.

 

Regards,

Sam

Hi .@samk

  The LCD screen I have has the RGB Vertical striped structure, supports 16:10 WXGA, 16.2M colors (RGB 6 bits + 2 bits dithering). Active screen size 1280H x 800V. 

Is there a Xilinx IP that is able to do this overlay?
