CI meaning in Computer Hardware ?

Answer: What is Common Interface mean?

In Digital Video Broadcasting, the Common Interface (also called DVB-CI) 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.

The Common Interface is the connection between the TV tuner (TV or set-top box) and the module that decrypts the TV signal (CAM). This module, in turn, then accepts the pay-to-view subscriber card, which contains the access keys and permissions.

The host (TV or set-top box) is responsible for tuning to pay TV channels and demodulation of the RF signal, while CAM is responsible for CA descrambling. The Common Interface allows them to communicate with each other. All Common Interface equipment must comply with the EN 50221-1997 standard. This is a defined standard that enables the addition of a CAM in a DTV receiver to adapt it to different kinds of cryptography. The EN 50221 specification allows many types of modules but only the CAM has found popularity because of the pay TV market. Indeed, one of Digital Video Broadcasting's main strengths is the option of implementing the required conditional access capability on the Common Interface.

This allows broadcasters to use modules containing solutions from different suppliers, thus increasing their choice of anti-piracy options.
