Brief Intro of Interlaced Video

Are you suffering from the annoying interlaced lines while viewing a video or movie displayed on your TV or computer? This kind of video is called interlaced video which uses two fields to create a frame in sequence. Field 1 contains all odd-numbered lines in the image, Field 2 contains all even-numbered lines. To put it simple, an interlaced video frame consists of Field 1 and Field 2.

Progressive Scan VS Interlaced Scan

Actually, there are two basic ways to record and display a video image:

Progressive Scan VS Interlaced Scan

Progressive Scan VS Interlaced Scan

Progressive scan: captures, stores, transmits, and displays an image in which all the lines of each frame are drawn in sequence - line by line, top to bottom. A progressive video is listed with the letter "p", such as 480p, 720p or 1080p.

Interlaced scan: The first displays the first and all odd numbered lines, from the top left corner to the bottom right corner. The second pass displays the second and all even numbered lines, filling in the gaps in the first scan. An interlaced video is listed with the letter "i", such as 480i or 1080i.

What is Deinterlace?

To prevent flicker and reducing transmission bandwidth, all analog camcorders, VCRs, broadcast television systems use interlaced scan. So, deinterlacing video is in practice the process of converting interlaced video into progressive video.

Why We Need to Deinterlace Video?

Most modern displays, such as LCD, DLP and plasma displays, only work in deinterlace mode, because they are fixed-resolution displays and only support progressive scan. In order to display interlaced signal on such displays, the two interlaced fields must be combined into one progressive frame with a deinterlacing process. To deinterlace the video, there are 3 free, simple and effective methods to remove the saw tooth type edge distortion below.
