I will argue that unless it’s 1920×1080 at 1:1 full raster, it’s not HD, and is rather “HDV.” But at the same time, this doesn’t mean HDV doesn’t have it’s place in when and where it could and should used.
Super Hi-Vision or SHV. It has four times the number of scanning lines used for HDTV, with four times as many pixels across, giving an image of 7680x4320, or 32 megapixels.
