Videoguard

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 BSkyB's Sky in the United Kingdom and Ireland and DirecTV in the United States, the former of which launched the digital version of the system in 1998. Several other broadcasters around the world use the VideoGuard system, including DirecTV (Colombia), DirecTV (LatinAmerica), Hot (Israel), Yes (Israel), Viasat (Scandinavia), SKY Italia (Italy), Sky Brazil (Brazil), Sky Network Television (New Zealand), Foxtel (Australia), Airtel DigitalTV (India), Tata Sky & Hathway (DVB-C) (India), Astro (Malaysia), TrueVisions (Thailand), D Smart (Turkey), TotalTV (Balkan), ONO (Spain), Canadian Broadcasting Corporation (Canada), China Central Television (China), SBB (Serbia), KabelBW (Germany), Vivacom (Bulgaria), Dolce (Romania), STAR TV/Fox International Channels (Asia), Cignal Digital TV (Philippines), Aora TV (Indonesia), Telecom Italia (Italy), OTAU TV (Kazakhstan), OTE TV (Greece), Oi TV (Brazil).
