| Abstract: | The article first introduces the current situation and the basic principle of DVB conditional access system. Then, it expatiates the common interface and DVB-CI protocol, analyzes the properties of the interface protocol from the application layer to the lowest layer. And it proposes the design method of the CI software, implement the DVB conditional access. Finally, it based on common interface which figures out the importance of role in conditional access system and shows a good future. |
