A video recording method where an image is created by flashing the Odd number lines of a digital image on the screen, followed rapidly by the Even number lines, thus making up the whole image. So, in 60i, only 30 full images are seen every second.

The following is a close up on my finger in an Interlaced Frame. Then I broke that image down into the Odd and Even fields.
