Over deze norm
ISO/TS 21219-10 defines the TPEG Conditional Access Information (CAI) application. It allows to protect the content of a TPEG service from unauthorized access. It further supports the management of subscriber information (e.g. Control Words and ECM) on the client devices in order to setup, prolong or revoke a subscription on a given client device. The application defines - the logical channel, for the transmission of the additional CA information (CAI), and - how the CAI is linked and synchronized to the scrambled content. This part of ISO/TS 21219 is related to conditional access applied on service component level. It is open for an integration of different conditional access systems.
