DVB-CI (Common Interface)

DVB-CI, or Digital Video Broadcasting - Common Interface, is a standard used in digital television to allow set-top boxes and TVs to access conditional access modules (CAMs). These modules enable viewers to decrypt pay-TV channels, allowing them to subscribe to various services without needing different equipment. Essentially, DVB-CI provides a universal slot for inserting a CAM that contains the necessary access rights, making the viewing experience easier and more flexible. This standard enhances interoperability, meaning devices from different manufacturers can work together seamlessly to deliver subscription content.
