XPression Studio systems with the XPression Clips option also have the PBUS option as part of the clips software. While PBUS is normally used to handle triggering video servers from a video switcher, PBUS can also be used to trigger XPression Scenes. This video shows how to add an XPression Scene to the PBUS register and what happens when it gets triggered. Ross Video Dashboard is used, for illustration purposes, to trigger PBUS register. However, this could be any switcher or device that can trigger PBUS.
