AUXILIARY BUS TRANSITIONS ON A VIDEO SWITCHER
First Claim
1. A method in a mix-effect architecture including a plurality of video processing units said method comprising:
- receiving a selection for a new video source to which a transition is desired from a current video source;
identifying a video processing unit that is not contributing towards video processing;
routing said new video source and said current video source to said identified video processing unit that is not contributing towards video processing;
routing an output of said identified video processing unit to an auxiliary bus output;
performing a transitional effect between said current video source and said new video source using said identified video processing unit; and
upon completion of the transitional effect, routing said new video source to said auxiliary bus output.

Abstract
A mix-effects bank architecture of a video switcher having a plurality of video processing units; and an internal switcher routing matrix. The internal switcher routing matrix routing, a video source currently providing a video feed to an auxiliary output and a desired new source for the auxiliary output to a video processing unit that is not contributing towards video processing and routing an output of said video processing unit to said auxiliary output. The video processing unit that is not contributing towards video processing performs a transitional effect for the auxiliary output.
