IBC Digital Video Production Practice Test

The device that enables instant switching between multiple camera feeds is a video switcher. In a production control room, the switcher acts as the hub that takes input from several cameras and routes the chosen feed to the on-air program output. The operator can switch from one camera to another in real time, often with quick transitions like cuts or fades, which is essential for live broadcasts where timing and continuity matter. Some switchers also handle additional tasks like picture-in-picture, overlays, or graphics, but their core function is seamless, immediate selection of the active camera feed. The teleprompter is for displaying scripts to the talent, the lighting board adjusts lighting, and the audio mixer handles audio levels—none of these switch camera feeds in real time.
