<p>A device for mixing video and audio signals originated from at least one remote camera (80) and one director camera (60) including a main unit (20) having a genlock circuitry (100, 200, 300, 400 and 500) for synchronizing the video signals of the remote and director cameras, and switching circuitry (1000) for combining these signals through the the use of removable special effects cartridges (30) or subassemblies (1150, 1900) that are pre-programmed for predetermined video switching patterns. The genlock circuitry 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 (60) from the remote camera (80). Device is connected through junction box (40) to director camera (60) and video tape recorder (70), and directly to remote camera (80).</p> |
