Interlaced and Progressive systems.
i come from the word "Interlaced" or "alternate scan lines," which is a form of scanned images. The approach is to create a visual image. TV will be generated by the first two pictures are created or scanned images into a single line that is 1,3,5,7,9 ... .... And so on until the last. Then the scanned images to create a line pair is connected. 2,4,6,8,10 ... .. Line of a quorum until a complete picture. How to create a picture or scan it. We may notice a blink of an image scan of the image due to the switch. Back and forth between odd and even lines of it.
The p comes from the word "Progressive" or "image by scanning the line" by creating an image or a scanned image is in contrast with Interlaced scanning alternate lines, it is not anymore. The image is scanned line by line down since. 1,2,3,4,5,6 ... .. Continue until the final lines. Thus, when the image is scanned in order to come to this. The flashing of the image will disappear because they do not need to be scanned and then switch to it.
If you want to compare it with p i which is better. It may be that p, because we could not see the screen flashing images it is still more than enough.
