The Digibox is a device marketed by Sky UK in the UK and Ireland to enable home users to receive digital satellite television broadcasts from the Astra satellites at 28.2° east. An Internet service was also available through the device, similar in some ways to the American MSN TV, before being discontinued in 2015. The first Digiboxes shipped to consumers in October 1998 when Sky Digital was launched, and the hardware reference design has been relatively unchanged since then. Compared to other satellite receivers, they are severely restricted. As of 2020, Sky Digiboxes have become largely outmoded, superseded by Sky's latest-generation Sky Q boxes and Sky Glass televisions; the previous generation Sky+HD boxes are still in use, however.
Top Up TV was a pay TV service in the United Kingdom that was launched in March 2004, operating on the digital terrestrial television platform. The service aimed to "top up" Freeview customers by providing additional content and services through encrypted TV channels unavailable to other viewers.
A home theater PC (HTPC) or media center computer is a convergent device that combines some or all the capabilities of a personal computer with a software application that focuses on video, photo, audio playback, and sometimes video recording functionality. Since the mid-2000s, other types of consumer electronics, including game consoles and dedicated media devices, have crossed over to manage video and music content. The term "media center" also refers to specialized application software designed to run on standard personal computers.
Cisco Videoscape was a majority owned subsidiary of News Corp, which develops software for the pay TV industry. NDS Group was established in 1988 as an Israeli start up company. It was acquired by Cisco in 2012 before being sold back to the private equity company Permira in 2018 for US$1 billion. The company is currently headquartered in Staines, United Kingdom.
Pirate decryption is the decryption, or decoding, of pay TV or pay radio signals without permission from the original broadcaster. The term "pirate" is used in the sense of copyright infringement. The MPAA and other groups which lobby in favour of intellectual property regulations have labelled such decryption as "signal theft" even though there is no direct tangible loss on the part of the original broadcaster, arguing that losing out on a potential chance to profit from a consumer's subscription fees counts as a loss of actual profit.
VideoGuard, 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. Since 2018 VideoGuard is improved and maintained by Synamedia. Its two most widely used implementations are 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.
Television encryption, often referred to as scrambling, is encryption used to control access to pay television services, usually cable, satellite, or Internet Protocol television (IPTV) services.
Nagravision is a company of the Kudelski Group that develops conditional access systems for digital cable and satellite television. The name is also used for their main products, the Nagravision encryption systems.
Conditional access (CA) is a term commonly used in relation to software and to digital television systems. Conditional access is that ‘just-in-time’ evaluation to ensure the person who is seeking access to content is authorized to access the content. Said another way, conditional access is a type of access management. Access is managed by requiring certain criteria to be met before granting access to the content.
In Digital Video Broadcasting, the Common Interface is a technology which allows decryption of pay TV channels. Pay TV stations want to choose which encryption method to use. The Common Interface allows TV manufacturers to support many different pay TV stations, by allowing to plug in exchangeable conditional-access modules (CAM) for various encryption schemes.
Astra 2D was one of the Astra communications satellites owned and operated by Société Européenne des Satellites (SES) and located at 28.2° East in the geostationary orbit until June 2015. It was a Hughes Space and Communications HS-376HP satellite bus and was launched from the Centre Spatial Guyanais in December 2000 to join Astra 2A and Astra 2B at 28.2° East, where it remained for its active life.
Dreambox is a series of Linux-powered DVB satellite, terrestrial and cable digital television receivers, produced by German multimedia vendor Dream Multimedia.
KeyFly is a conditional access (CA) system developed by SIDSA which is compatible with the DVB-CSA platform. The system is based on SIDSA MACtsp processors, and conditional-access modules for it can integrate the card directly into the CAM.
Downloadable Conditional Access System or DCAS was a proposal advanced by CableLabs for secure software download of a specific Conditional Access client which controls digital rights management (DRM) into an OCAP-compliant host consumer media device. The National Cable & Telecommunications Association (NCTA) proposed that DCAS be used as a substitute for physical CableCARDs, a standard also created by CableLabs for which products began appearing in August 2004 as part of industry compliance to the FCC mandate, which in turn is pursuant to the Telecommunications Act of 1996. DCAS is growing in popularity as a less expensive alternative for CableCARD, with major North American operator deployments from Cablevision and Charter. DCAS deployments can be expected to grow in the coming years, thanks to favorable regulatory view from the STELA Reauthorization Act of 2014 and FCC appointing a Downloadable Security Technical Advisory Committee, and wider support for key ladder (K-LAD) functionality from system-on-chip (SoC) vendors and set-top box manufacturers.
Card sharing, also known as control word sharing, is a method of allowing multiple clients or digital television receivers to access a subscription television network with only one valid subscription card. This is achieved by electronically sharing a part of the legitimate conditional access smart card's output data, enabling all recipients to gain simultaneous access to scrambled DVB streams, held on the encrypted television network.
A free-to-air or FTA Receiver is a satellite television receiver designed to receive unencrypted broadcasts. Modern decoders are typically compliant with the MPEG-2/DVB-S and more recently the MPEG-4/DVB-S2 standard for digital television, while older FTA receivers relied on analog satellite transmissions which have declined rapidly in recent years.
Addressability is the ability of a digital device to individually respond to a message sent to many similar devices. Examples include pagers, mobile phones and set-top boxes for pay TV. Computer networks are also addressable via the MAC address on Ethernet network cards, and similar networking protocols like Bluetooth. This allows data to be sent in cases where it is impractical to control exactly where or to which devices the message is physically sent.
Unibox is a satellite, cable and terrestrial digital receiver. It has been distributed widely for use with Pay TV. It also enables the receiver to store digital copies of MPEG TS on internal harddisk or networked filesystems.
VBox Home TV gateway is a network-enabled live TV tuner and PVR HDTV set-top-box produced by VBox Communications Ltd.
Enigma2, the second generation of Enigma software, is an application used in Linux-based Digital Video Broadcasting receivers or TV set-top boxes and Internet Protocol television receivers. It creates a graphical user interface to control the said devices using a remote control and provides features such as tuning available satellite transponders, cable channels and terrestrial television transmitters or accessing material via Internet Protocol television (IPTV), watching a TV program or listening to radio, time shifting, Digital video recorder, streaming media programs to other devices, etc. Other features are available through plugins – for example Electronic program guide (EPG), Hybrid Broadcast Broadband TV (HbbTV), access to TV archives and movie databases, playback of multimedia files, viewing photos, etc.
