摘要：
A digital effects unit (52) is integrally combined within a video switcher apparatus by interrupting various selected video signal and control paths in the switcher, and re-routing the corresponding signals to respective inputs of the digital effects unit. The resulting manipulated video and key output signals therefrom are supplied to a downstream mixer (17) which combines the digital effects with normal switcher effects.
