What is the technical differences between 1080i and 1080p?
1080p is better than 1080i resolution, and this will be most visible when there is rapid motion in the material being displayed. Note that 1080 is a high definition “resolution” (technically 720p or higher is HD). In general, the higher the resolution the clearer the image may be. On a 1080p display (e.g. HDTV) each frame of the image is ‘drawn’ progressively (the origin of the “p” in 1080p (or 720p)) one horizontal line after another (i.e. line 1,2,3,4 ….1080). On a 1080i display the image is drawn as two interlaced”fields” (the “i” in 1080i) created by drawing the odd (1,3,5, …1079) and even (2,4,6, 1080) lines, respectively. Each frame of the 1080i image has the same number of lines of resolution (1080), but because it is drawn in two 540 line halves there is a slight time lag between when the two fields are sampled, and if there is fast motion in the original image (e.g. a tennis or football moves on the screen) the two fields may be visibly different and, when interlaced to cr
