This International Standard specifies IPMP (Intellectual Property Management and Protection) on the MPEG-2 system, including: a) syntax and semantics for IPMP control information which includes tool list, tool container and rights container; b) syntax and semantics for IPMP descriptors, which facilitates IPMP protection signalling; c) syntax and semantics of IPMP data extending from the common base class IPMP_Data_BaseClass to support the following functionalities: — mutual authentication for IPMP tool to IPMP tool as well as IPMP tool to terminal communication, — the requesting by IPMP tools of the connection/disconnection to requested IPMP tools, — the notification to IPMP tools of the connection/disconnection of IPMP tools, — common IPMP processing, — IPMP tool to/from user interaction; d) syntax and semantics for IPMP information carriage to and from IPMP tools; e) syntax and semantics for the request and transfer of content and IPMP tools between terminals; f) XML syntax and semantics for the description of the environment in which the MPEG-2 Terminal/application is operating; g) a list of registration authorities required for the support of the specifications found herein. This document is organized as follows. Clause 1 provides an introduction to the document. Clause 4 explains the compatibility between the Conditional Access framework and MPEG-2 IPMP framework. Clause 5 provides an overview of the process supported by the IPMP framework, and identifies different normative elements in this process. Clause 6 provides specifications for components identified in Clause 5. Clause 7 provides specifications for the messaging architecture and all supported messages.
