Quad Input RGB VIC
The Quad Input RGB VIC consists of four sets of RGBHV inputs and operates in a manner similar to a switcher. The four inputs are multiplexed so that only one is enabled at a specific time. Software selects the desired input channel through the IIC bus and ensures that only one RGB VIC is enabled. When one of the channels assigned to the Quad RGB VIC is selected, the /SEL_VIC line to the Video Processor is enabled.
