'''VideoGuard''' (sometimes referred to simply as ''NDS''), produced by [[NDS Group|NDS]], is a digital [[encryption]] system for use with [[conditional access]] television broadcasting. It is used on digital [[satellite television]] systems – some of which are operated by [[News Corporation (1980–2013)|News Corporation]], which owned about half (49%) of NDS until its sale to [[Cisco]] in 2012 (becoming [[Cisco Videoscape]] division).<ref>{{Cite web|url=http://newsroom.cisco.com/press-release-content?type=webcontent&articleId=712002|title = Cisco Announces Intent to Acquire NDS}}</ref> Since 2018 VideoGuard is improved and maintained by [[Synamedia]] (Cisco's spun-off company based on its former Videoscape division). Its two most widely used implementations are '''[[Sky UK|Sky]]''' in the [[United Kingdom]] and [[Republic of Ireland|Ireland]] and '''[[DirecTV]]''' in the [[United States]], the former of which launched the digital version of the system in 1998.
