Video Deinterlace - Convert Interlaced Video to Progressive

The images on screen are usually drawn by video displays in the manner of interlaced scan or progressive scan. Thus, the videos that we watch falls into category of either interlaced video or progressive video (in terms of the ways of showing the motion of image). Then what are the differences between them? Which one works better in video playing? Are they mutually-converted?

Part 3: Interlaced vs Progressive: Which One Works Better in Video Playing?

Above all, let's beat out the conceptions of interlaced scan/video and progressive scan/video.

Part 1: What Is Interlaced Scan/Video?

Interlaced scan is commonly used in traditional TV systems, such as NTSC, in which half of the picture appears on the screen at a time, followed quickly the other half later. Put it more concretely. Two fields are used to create a frame by interlaced scanning. All the odd lines are contained in one of the two fields, while the even lines are contained in another one. Sixty fields are scanned by a television in every second (half odd and half even). Then a full frame will be created by the combination of the two sets of the thirty fields in every 1/30th of a second, thus generating a display of 30 frames per second. Interlaced videos are therefore those videos that are made in the manner of interlaced scan mentioned above.

Part 2: What Is Progressive Scan/Video?

As long as you understand what interlaced scan is, the conception of progressive scan will be easier to get. Progressive scan means that the lines are drawn at once sequentially, then a complete single frame image can be painted in every 1/60th of a second. It is widely used in computer monitors, CRTs, and many cutting-edge television displays. Likewise, progressive video refers to videos made by progressive scan.

Now, let's come back to the questions raised at the beginning of this passage.

Part 3: Interlaced vs Progressive: Which One Works Better in Video Playing?

Obviously, progressive scan outperforms interlaced scan. Progressive scan allows to double the details delivered in the same amount of time consumed by interlaced scan and more detailed images to be displayed on the screen. Comparatively, interlaced scan results in flickering, low quality and low resolution of the video.

Part 4: Can Interlaced and Progressive Be Converted Mutually?

Sure. Deinterlace functions as the bridge between interlaced video and progressive video. Then how to achieve deinterlacing?
