A set-top box (STB), also known as a cable box or receiver and historically television decoder, is an information appliance device that generally contains a TV-tuner input and displays output to a television set and an external source of signal, turning the source signal into content in a form that can then be displayed on the television screen or other display device. They are used in cable television, satellite television, and over-the-air television systems as well as other uses.
ITV Digital was a British digital terrestrial television broadcaster which launched a pay-TV service on the world's first digital terrestrial television network. Its main shareholders were Carlton Communications plc and Granada plc, owners of multiple licences of the ITV network.

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 As of 2020, Sky Digiboxes have become largely outmoded, superseded by Sky's latest-generation Sky Q boxes and Sky Glass televisions; the previous generation Sky+HD boxes are still in use, however.

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.
A conditional access module (CAM) is an electronic device, usually incorporating a slot for a smart card, which equips an integrated digital television or set-top box with the appropriate hardware facility to view conditional access content that has been encrypted using a conditional access system. They are normally used with direct-broadcast satellite (DBS) services, although digital terrestrial pay TV suppliers also use CAMs. PC Card form factor is used as the Common Interface form of Conditional Access Modules for DVB broadcasts. Major CAM manufacturers include: Neotion, SmarDTV and SMIT.
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.
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.
Sky+ is a discontinued personal video recorder (PVR) and subscription service from the satellite television provider Sky in the UK and Ireland.

Sky was not actively promoting the service and the service has quietly been discontinued for new customers as of 2021.
Sky+ HD was the brand name of the HDTV service launched by Sky plc on 22 May 2006 in the United Kingdom and Ireland to enable high definition channels on Sky to be viewed. For the first two years after launch, the service was branded Sky HD. The service requires the user to have a Sky+ HD Digibox and an HD ready TV. A subscription to the original HD pack carries an extra fee of £10.25 a month in addition to the standard Sky subscription, allowing customers to view HD channels corresponding to the channel packs subscribed to. Additional Pay-Per-View events on Sky Box Office HD are not available to customers unless they subscribe to the Sky HD pack.
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.
Satellite television is a service that delivers television programming to viewers by relaying it from a communications satellite orbiting the Earth directly to the viewer's location. The signals are received via an outdoor parabolic antenna commonly referred to as a satellite dish and a low-noise block downconverter.

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.
