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.
