LCD display feed from external source

Hello all,

I have a video processing algorithm that I would like to make available to my Canon 5d iii. I know I can get live video from it into my computer, now I would like to take the processed video and feed it back into the camera's LCD display so the user could use it without an external monitor or a laptop display. Is there a way to feed external video into the 5d iii's display?

Thanks.
