Conditional Access System
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.

Digital Television
Digital television (DTV) is the transmission of television signals using digital encoding, in contrast to the earlier analog television technology which used analog signals. At the time of its development it was considered an innovative advancement and represented the first significant evolution in television technology since color television in the 1950s. Modern digital television is transmitted in high-definition television (HDTV) with greater resolution than analog TV. It typically uses a widescreen aspect ratio (commonly 16:9) in contrast to the narrower format of analog TV. It makes more economical use of scarce radio spectrum space; it can transmit up to seven channels in the same bandwidth as a single analog channel, and provides many new features that analog television cannot. A transition from analog to digital broadcasting began around 2000. Different digital television broadcasting standards have been adopted in different parts of the world; below are the more widel ...

Nagravision
Nagravision (or Nagra Kudelski or simply Nagra) 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. Analog system An analog Nagravision system (''Syster'') for scrambling analog satellite television programs was used in the 1990s. In this line-shuffling system, bottom 32 lines of the PAL TV signal are shifted in time by one video field, and read out in permuted order under the control of a pseudorandom number generator. A smartcard security microcontroller (in a key-shaped package) decrypts data that is transmitted during the blanking intervals of the TV signal mixed with teletext and extracts the random seed value which contains present line combination needed for reverting the picture back. The system also permitted the audio signal to be modulated at 12.8 kHz using a frequency mixer. Digital systems 4 currently used version ...
