Which term describes interlaced/interleaved video?

• A. Jam synch
• B. Key Frame
• C. Interlaced/Interleaved video
• D. Group Walla

Answer: (C)

Interlaced video describes a scanning method where each frame is built from two fields captured at slightly different times—one field carries the odd-numbered lines, the other the even-numbered lines. Those fields are displayed in rapid succession to create the appearance of a full frame, effectively increasing motion smoothness at a lower bandwidth. This is why formats labeled with “i” (like 1080i) are called interlaced; interleaved is another way people describe the same concept because the image is formed by interweaving the two fields in time. In practice, you see it in older broadcast standards and CRT displays; when deinterlacing is applied properly, the content looks correct, but without it, fast motion can show combing artifacts. The term you’re looking for precisely captures this scanning method, so it’s the best fit. The other terms refer to unrelated concepts (compression reference frames or nonstandard terms) and do not describe how the video image is scanned.
