ABSTRACT:
A device for mixing video and audio signals originated from at least one remote camera and one director camera including a main unit having a circuit for synchronizing the video signals of the remote and director cameras, and a circuit for combining these signals through the use of removable special effects cartridges or subassemblies that are pre-programmed for predetermined video switching patterns. The circuit for synchronizing the video signals separates the sync signals from the director and remote cameras, locks the vertical, horizontal and color subcarrier on the director camera from the remote camera. The device is connected through junction box to director camera and video tape recorder, and directly to remote camera.
