The ? video signal must be converted to a digital signal before an analog video signal can be recorded by a DVR.

• A. Composite
• B. Component
• C. S-Video
• D. RGB

Answer: (A)

Video recorded by a DVR is stored as digital data, so any incoming analog signal must be converted to digital. Composite is the simplest and most commonly supported analog format for DVRs, typically connected over a single RCA cable; the DVR’s capture hardware is designed to digitize this standard as it comes in. While higher-quality analog formats like component, S-Video, and RGB exist, they’re less universally supported on consumer DVRs and often require different inputs, making composite the usual path for digitizing before recording.
