What Is CI Module In Dish TV?
NEW DELHI: DTH major Dish TV on Monday launched its Conditional Access Module (CAM) device, which allows consumers with set-top boxes of other DTH service providers to switch to Dish TV's feed of television channels.
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.
