Digital Effects Integration in a Video Switcher

Enhancements can be made to the control panel and the internal architecture of a video production switcher to simplify operation of a digital effects device from the switcher panel. Presently, inputs to digital effects devices are typically selected from auxiliary or external routing buses, and the output of the digital effects enters the switcher as an input. If a key channel is used and transformed with the digital effects, key-processing circuitry with additional key input routing is required. The output of the digital effects device still needs to be combined with other video sources into the final output. The ability to select and route sources, generate key signals, and mix output video are common to the video production switcher. With some additional hardware and control enhancements to the switcher, a digital effects device can easily be controlled with an efficiency of hardware.
