ISO/IEC 23000-4:2009

Information technology — Multimedia application format (MPEG-A) — Part 4: Musical slide show application format

ISO/IEC 23000-4:2009 specifies signaling of content governance and protection of musical slide show application format based on MPEG-21 Part 4: Intellectual Property Management and Protection (IPMP) Components Base Profile and MPEG-21 Part 5: Rights Expression Language (REL) Mobile And optical Media (MAM) Profile.

It may be used to protect any content of musical slide show application format: MPEG-1 Audio Layer 3 (ISO/IEC 11172-3), JPEG images (ISO/IEC 10918-1), MPEG-4 LASeR (ISO/IEC 14496-20) animation script and 3GPP timed text (3GPP TS 26.245) in any combinations of content protection.

ISO/IEC 23000-4:2009 specifies

• the file structure, metadata, and synchronization of contents as in ISO/IEC 23000-4,
• the use of file format (ISO/IEC 14496-14) in using content governance and protection,
• the metadata for governance and protection using MPEG-21 Part 4: IPMP Components Base Profile and MPEG-21 Part 5: REL MAM Profile, encapsulated in MPEG-21 Part 2: Digital Item Declaration (DID) .

It does not specify certain protection tools to be used in content protection, therefore it ensures a simple and flexible protection scheme.
