Which device is used to switch between video sources and can also composite sources for effects?

• A. Bus
• B. Camera Control Unit
• C. Switcher
• D. Broadcasting

Answer: (C)

Switching between video sources and combining them for effects is the job of a video switcher. In a multi-camera or multi-source setup, the switcher acts as the central control that selects which input feeds the final program output. It also handles transitions and compositing, such as picture-in-picture, wipes, fades, and even chroma-key effects to integrate different sources into one seamless shot. A bus is a signal path used inside equipment, not the device that switches sources. A Camera Control Unit adjusts camera settings like color and exposure, not which sources are on air. Broadcasting refers to the overall process of producing and transmitting content, not a single hardware device.
