VideoCrypt
VideoCrypt is a cryptographic, smartcard-based conditional access television encryption system that scrambles analogue pay-TV signals. It was introduced in 1989 by News Datacom and was used initially by Sky TV and subsequently by several other broadcasters on SES' Astra satellites at 19.2° east. Users Versions Three variants of the VideoCrypt system were deployed in Europe: VideoCrypt I for the UK and Irish market and VideoCrypt II for continental Europe. The third variant, VideoCrypt-S was used on a short-lived BBC Select service. The VideoCrypt-S system differed from the typical VideoCrypt implementation as it used line shuffle scrambling. * Sky NZ and Sky Fiji may use different versions of the VideoCrypt standard. * Sky NZ used NICAM stereo for many years until abandoning it when the Sky DTH technology started replacing Sky UHF. Operating principle The system scrambles the picture using a technique known as "line cut-and-rotate". Each line that made up each picture ...

Television Encryption
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. History Pay television exists to make revenue from subscribers, and sometimes those subscribers do not pay. The prevention of ''piracy'' on cable and satellite networks has been one of the main factors in the development of Pay TV encryption systems. The early cable-based Pay TV networks used no security. This led to problems with people connecting to the network without paying. Consequently, some methods were developed to frustrate these self-connectors. The early Pay TV systems for cable television were based on a number of simple measures. The most common of these was a channel-based filter that would effectively stop the channel being received by those who had not subscribed. These filters would be added or removed according to the subscription. As the number of television channels on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BBC Select (1992–1995)
BBC Select was an overnight television service run by the BBC during the hours when BBC1 or BBC2 had closed down, usually between 2am and 6am. The channel showed programming intended for specialist audiences, such as businessmen, lawyers, nurses and teachers, and was designed to be viewed after broadcast via a video recording. It was funded by a subscription, and most programming was scrambled. History The service was officially launched during the overnight hours of 21 January 1992, and ran on both BBC1 and 2. A spiritual predecessor of BBC Select intended for members of the British health care profession, called British Medical TV (BMTV), aired encrypted health care-related programming during the overnight hours of BBC1 and 2 between 1989 and 1992. BBC Select experimented with programming for specific audiences, and with overnight broadcasts, experience that the BBC would later use when broadcasting the BBC Learning Zone. By broadcasting the programming then, it allowed t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conditional Access
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 is by requiring certain criteria to be met before granting access to the content. In software Conditional access is a function that lets you manage people’s access to the software in question, such as email, applications, and documents. It is usually offered as SaaS (Software-as-a-Service) and deployed in organizations to keep company data safe. By setting conditions on the access to this data, the organization has more control over who accesses the data and where and in what way the information is accessed. When setting up conditional access, access can be limited to or prevented based on the policy defined by the system administrator. Fo ...

Scrambler
In telecommunications, a scrambler is a device that transposes or inverts signals or otherwise encodes a message at the sender's side to make the message unintelligible at a receiver not equipped with an appropriately set descrambling device. Whereas encryption usually refers to operations carried out in the digital domain, scrambling usually refers to operations carried out in the analog domain. Scrambling is accomplished by the addition of components to the original signal or the changing of some important component of the original signal in order to make extraction of the original signal difficult. Examples of the latter might include removing or changing vertical or horizontal sync pulses in television signals; televisions will not be able to display a picture from such a signal. Some modern scramblers are actually encryption devices, the name remaining due to the similarities in use, as opposed to internal operation. In telecommunications and recording, a ''scrambler'' (als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiji
Fiji ( , ,; fj, Viti, ; Fiji Hindi: फ़िजी, ''Fijī''), officially the Republic of Fiji, is an island country in Melanesia, part of Oceania in the South Pacific Ocean.

About three-quarters of Fijians live on Viti Levu's coasts: either in the capital city of Suva; or in smaller urban centres such as Nadi—where tourism is the major local industry; or in Lautoka, where the Sugarcane, sugar-cane industry is dominant. The interior of Viti Levu is sparsely inhabited because of its terrain. The majority of Fiji's islands were formed by Volcano, volcanic activity starting around 150 million years ago. Some geo ...

BBC Two
BBC Two is a British free-to-air public broadcast television network owned and operated by the BBC. It covers a wide range of subject matter, with a remit "to broadcast programmes of depth and substance" in contrast to the more mainstream and popular BBC One.

It is a comparatively well-funded public-service network, regularly attaining a much higher audience share than most public-service networks worldwide. Originally styled BBC2, it was the third British television station to be launched (starting on 21 April 1964), and from 1 July 1967, Europe's first television channel to broadcast regularly in colour. It was envisaged as a home for less mainstream and more ambitious programming, and while this tendency has continued to date, most special-interest programmes of a kind previously broadcast on BBC Two, for example the BBC Proms, ...
