So, I work at a local a venue that is being rented out. We are supposed to provide lighting and AV support to them but the center only is allowing me to do both. This wouldn't be a problem if we didn't have a lighting show that needs to be controlled and an AV system that is downstairs from the light board. We have apple TV on the av system but I have ignored its potential but I believe I can enable something on my computer (mac) to control the AV show (pictures, videos and music) remotely. How would I do that with APPLE TV without having my computer screen be up and people seeing what was on it (during transitions) Thank you!
