VideoGuard (sometimes referred to simply as
NDS), produced by
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, which owned about half (49%) of NDS until its sale to
Cisco in 2012. Its two most widely used implementations are

United Kingdom and
