Which statement best describes the relation of enhanced definition television to progressive scanning?

• A. Progressive scanning and EDTV improve picture quality over standard definition
• B. EDTV reduces color depth
• C. EDTV requires 4K to function
• D. Progressive scanning is unrelated to EDTV

Answer: (A)

Progressive scanning and EDTV improve picture quality over standard definition by moving away from interlaced 480i to progressive 480p, so each frame is drawn in full. EDTV, or Enhanced Definition Television, uses progressive scanning to deliver a higher-quality SD signal, which reduces interlacing artifacts and yields crisper edges and smoother motion on compatible displays. That combination explains why this statement is the best choice. The other options are off-base because EDTV doesn’t inherently reduce color depth, it doesn’t require 4K, and progressive scanning is indeed related to EDTV (EDTV uses progressive scanning).
