Interlaced

For video signals and displays, ones that paint each image in two passes (fields) down the screen, with the first pass creating the odd lines and the second the even lines; this reduces bandwidth for transmitted video, but causes flicker in computer graphics.


A method of displaying a video image in which all the odd lines are drawn first and then all the even lines are drawn next. Interlaced video uses two fields (all the odd lines or all the even lines) to create a single frame or complete image. Interlaced video is the standard for analog NTSC video distribution. nterlaced video is different from non-interlaced video, which paints each line on the screen in order. The interlaced video method was developed to save bandwidth when transmitting signals but it can result in a shakier, less detailed image than non-interlaced video. Most computer screens use non-interlaced video. The digital television standard will allow for the use of both interlaced and non-interlaced video formats with the highest quality HDTV signal being in an interlaced format.
