Abstract
The V-High multimedia broadcasting system uses a conditional access and conditional playback system that is robust under mobile broadcasting reception conditions and also flexible to the new service styles, such as file based broadcasting, while expanding the access control system already used in the terrestrial digital broadcasting. Although the conditional access (CA) interface has more functionalities than that of conventional systems, the implementation detail has been left to the manufactures. Manufacturers has freedom on the implementation, however, the implementation cost tends to be growing. In this paper, we describe the back ground and the design concept of the NOTTV IC card, which is for the access control of the V-High multimedia broadcasting, expecting to incubate the variety of receiver development environments.
