Video interlace and deinterlace

What is interlace

Video and film consist of a series of still images played in rapid succession. Each image is a frame. While a film frame is always a single entity, all television systems divide each image into a series of scan lines. All mainstream analog and many digital television systems arrange the scan lines of each frame into two consecutive fields, one containing all even lines, another with the odd lines. The fields are then displayed in succession at a rate twice that of the nominal frame rate. The process of dividing frames into half-resolution fields at double the frame rate is known as interlacing.

Deinterlace - convert interlaced video into progressive video

For most modern LCD and plasma displays, they are currently not able to work in interlaced mode. To combat interlace artifacts, all LCD and plasma consumer television sets have built-in circuitry that converts interlaced video into progressive video. The process of converting interlaced video into progressive is called de-interlacing. If done poorly, de-interlacing can introduce image degradation.
