Digital video Services

Digital video is a type of video recording system that works by using a digital, rather than analog, manifestation of the video signal. This universal term is not to be mixed up with the name DV, which is a distinct type of digital video. Digital video is most often recorded on tape, then allocated on optical discs, usually Dvds. There are exceptions, such as video cameras that record directly to Dvds, Digital8 camcorders which encode digital video on traditional analog tapes, and the most recent JVC Everio G camcorders which record digital video on hard disks.
