TV standards through 1080p. 1080p (also known as Full HD or FHD and BT.709) is a set of HDTV high-definition video modes characterized by 1080 horizontal lines of vertical resolution and progressive scan, as opposed to interlaced, as is the case with the 1080i display standard.n addition is the high cost of using more bandwidth for one 1080p/24 channel than that necessary for a 1080i or even a 720p channel and for only those relatively few subscribers who have HDTV devices that can display 1080p/24 being an efficient use of their limited bandwidth.
