Abstract
A switcher with depth processing includes a depth processor module. External depth data, or internally generated depth data, are input to the depth processor to generate a priority signal for combining key video signals as layers between a background and a foreground video signal. Further a composite depth signal is generated for the combined key video signals for subsequent processing so that additional key video layers may be intersected and intertwined with the key video layers in the combined video signals.
