HDV 720p closely matches broadcast 720p video standard in terms of scanning type, frame rate, frame size, aspect ratio and data rate. Presently, JVC is the only manufacturer of HDV 720p camcorders. JVC was the first to release an HDV camcorder, the handheld GR-HD1. Later JVC shifted its HDV development to shoulder-mounted cameras.
HDV 1080i is an interlaced video standard. Interlaced video has been a useful compromise for decades due to its ability to display motion smoothly while reducing recording and transmission bandwidth. Interlaced video is still being used in acquisition and broadcast, but interlaced display devices are being phased out.
Modern flat-panel television sets that utilise plasma and LCD technology are inherently progressive. All modern computer monitors use progressive scanning as well.
There is no separate standard for HDV 1080p recording. Instead, the HDV 1080i specification defines optional progressive recording modes, which are getting popular, as the users become more interested in shooting digital movies and creating content for the Web. All HDV camcorders that can record in 1080p format can also record native 1080i video.
