Interlacing

Interlacing

A system that reduces bandwith by half by using an upper and lower field to display each frame of video. One field carries even video lines while the other carries odd video lines. Interlacing is also used in computer graphics in order to display high resolution images on inexpensive monitors. Interlacing can causes flickering and can create jagged edges in parts of an image which can be smoothed out with deinterlacing filters in graphics software or video processing and compression programs.
