What major change in enhanced definition TV improves picture quality over standard definition TV?

• A. The use of progressive scanning and EDTV
• B. Higher frame rate interlaced scanning
• C. Increased color depth via wider color gamut
• D. Analog master signal

Answer: (A)

The key idea here is progressive scanning. Enhanced Definition TV improves picture quality by displaying full frames in sequence rather than splitting each frame into two interlaced fields. In standard definition, 480 lines are often shown in an interlaced 480i format, which can cause flicker and motion artifacts. By adopting 480p (progressive) in EDTV, every line of each frame is drawn in order, giving a crisper, smoother image and better handling of motion. The other options touch on color depth, frame rate, or legacy analog signals, but they don’t define the main upgrade EDTV brings over standard definition.
