Цитат:
CI+ is a further development of the DVB-CI standard 1.0, which was previously used in TV sets and CI modules. With CI the encrypted digital programmes are decoded in the module and then passed on directly to the TV set. With CI+ the encrypted digital programmes are encrypted again between the module and the TV. In this way it is also possible to ensure that the minimum requirements for parental control and copy protection are met. A TV set with CI+ specification recognises whether a CI+ module is being used. If a CI+ is not being used then encrypted digital programmes may possibly not be shown.
