Not sure if this is the best place to post this.

I am installing a projector in a hall. The purpose is to show a live stream of a band playing a song while also showing the lyrics of the song on top of the live image.
Does anybody have a suggestion of how to best achieve this? I can set-up an IP camera on a laptop no problem, it is knowing how to stream this and the lyrics at the same time to the projector.

Thanks

Mike
