Description of 20/30402763 DC 2020

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

  1. the logical channel, for the transmission of the additional CA information (CAI), and

  2. 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.

NOTE

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.
