This standard 20/30402763 DC BS EN ISO 21219-10. Intelligent transport systems. Traffic and travel information (TTI) via transport protocol experts group, generation 2 (TPEG2) is classified in these ICS categories:
- 03.220.01 Transport in general
- 35.240.60 IT applications in transport and trade
This part of ISO/TS 21219 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.
The basic concept behind the CAI application is to transport CAI in separate TPEG service components of a dedicated application type and to define an SNI table that contains the link between scrambled content and related CAI.
