The first DVB Common Interface (DVB-CI) specification was created in 1997. It describes the interface between a Conditional Access Module (CAM) and the host, which is typically a TV set. CI Plus was introduced in 2007, version 1.4 was introduced in September 2013 and version 2.0 was published as a DVB BlueBook in 2015/2016.
The first DVB Common Interface (DVB-CI) specification was created in 1997. It describes the interface between a Conditional Access Module (CAM) and the host, which is typically a TV set. All the conditional access functionality is provided by the CAM module whereas the host provides the necessary tuning functionally and presents audio and video. In the first DVB-CI version the content was transferred in the clear between the module and the host. This security loophole was resolved with the introduction of CI Plus in 2007. Being mandated by a European Directive, CI Plus slots are present in basically all TV sets sold in Europe.
DVB will continue to work on new versions of the CI Plus specification. In addition to new features and functionality, the current PCMCIA base physical form factor will be replaced by a more compact interface solution (CI Plus 2.0).
DVB-CI Plus 1.4 adds new features such as extensions to the CI Plus browser and the handling of multiple encrypted streams (multi stream). Other new features include the ability to route high-bandwidth IP streams through the Conditional Access Module (CAM), the ability for the CAM to control those IP streams, the new “Online Service Descriptor Table”(OSDT), and support for IP Multicast. These new features enable IPTV straight to the television set without the need for a set-top box.
DVB-CI-Plus 2.0 was published as a DVB BlueBook in 2015/2016 and can be found on the page with the full list of DVB standards.
