There was a topic on the old forum on the use of augmented reality with CasparCG, similar to the Sportvision 1st & 10 System used in American football broadcasts. I added to the thread with the findings from my research and development on my own version of it which utilized CasparCG, and I wanted to publish my full findings to the community, in case they may be of use to anyone else. This paper was originally submitted to SMPTE.

I am happy to add or clarify anything if needed.
