ISO/IEC 13818-11:2004

Overview - ISO/IEC 13818-11:2004 (MPEG-2 IPMP)

ISO/IEC 13818-11:2004 defines IPMP (Intellectual Property Management and Protection) for MPEG‑2 systems. It specifies the syntax and semantics for IPMP control information, descriptors, messages and data objects used to enable interoperable, flexible and robust protection of MPEG‑2 content. The standard supports secure content delivery while allowing combination with proprietary IPMP tools so different business models and security levels can coexist within MPEG‑2 transport and program streams.

Keywords: ISO/IEC 13818-11:2004, MPEG-2 IPMP, IPMP, content protection, DRM, MPEG-2 systems

Key topics and technical requirements

• IPMP Control Information - formats for tool lists, tool containers and rights containers used in Transport Stream (TS) and Program Stream (PS).
• IPMP Descriptors and Signalling - descriptors to signal protection and enable discovery of required IPMP tools in MPEG‑2 streams.
• IPMP_Data_BaseClass and Messages - base class and message types supporting:
  • mutual authentication between IPMP tools and terminals,
  • tool connection/disconnection requests and notifications,
  • common IPMP processing primitives,
  • user interaction messages.
• IPMP Stream and Decoder Model - syntax and processing model for IPMP streams and how decoders interact with tools.
• Information carriage and transfer - mechanisms for delivering IPMP information to/from tools, and messages for requesting/transferring content or tools between terminals (annexes cover device messaging and transfer).
• Selective decryption & Watermarking - normative annexes describe selective decryption configuration and audio/video watermarking configuration and notifications.
• XML Environment Description - XML schema for describing terminal/application environment.
• Registration Authorities - list and procedures for authorities supporting the specification.
• Compatibility with Conditional Access (CA) - informative guidance on coexistence and backward/forward compatibility with CA frameworks.

Practical applications

• Secure distribution of MPEG‑2 video/audio over broadcast, IPTV and managed networks.
• Enabling interoperable DRM workflows where multiple vendors’ IPMP tools coexist.
• Implementing selective decryption, watermarking and controlled user interactions in set‑top boxes and media players.
• Tool/content transfer between terminals in distributed environments (e.g., device-to-device provisoning).

Who should use this standard

• Broadcast engineers and content distributors designing protected MPEG‑2 workflows
• Set‑top box, media player and silicon vendors implementing IPMP tool frameworks
• DRM/IPMP tool developers and system integrators
• Standards and compliance teams verifying MPEG‑2 protection interoperability

Related standards

• Other parts of the ISO/IEC 13818 (MPEG‑2) family - system, video and audio specifications
• Conditional Access (CA) frameworks used in broadcasting (compatibility addressed in the standard)

This standard is essential for anyone implementing interoperable content protection and DRM signaling within MPEG‑2 systems.
