Interlaced scanning may be described as what?

Interlaced scanning is a method used in video display technology where the image is created by displaying two fields in alternation, one comprised of odd-numbered lines and the other consisting of even-numbered lines. This technique allows for a full image to appear on the screen by first rendering every other line, which reduces the amount of data that needs to be transmitted at any one time while still delivering the perception of a complete picture.

By alternating the display of these two fields, interlaced scanning helps to reduce the bandwidth required for broadcasting, which was particularly beneficial in earlier television technologies and contributes to smoother motion portrayal in fast-moving video content. This method is distinct from progressive scanning, which draws the entire image line by line in a single pass, and does not fit the definitions represented by the other options.
