Basically, interlaced is like TV and progressive is like film or 50i is PAL, 60i is NTSC and 24P is film. TV uses interlaced scanning to conserve bandwidth. Each frame is displayed on the screen twice in what is called a pass or field. With each pass the odd and then even lines are scanned in a 1/50th second. A complete frame is scanned 25 times per second. With a progressively scanned system the entire frame of pixels is conveyed every 1/50th second at 25 times per second. In the US the lines are scanned every 1/60th second. 1080i is an interlaced format consisting of 1080 active lines with a 16:9 aspect ratio and the format uses square pixels. 720P is a progressive format and it consists of 720P active lines, again it uses a 16:9 aspect ratio and square pixels.
