Overview
ISO/IEC 23000-5:2011 - Media streaming application format (part of the MPEG-A family) defines a standardized digital item structure and file format for streaming governed audio, video, metadata and related presentation information to end-user devices. The standard specifies how media resources are represented, protected and delivered over common transport protocols (for example MPEG-2 Transport Stream and RTP/UDP/IP), and includes informative implementation examples for use cases such as IPTV, digital broadcasting without return channel, and interactive streaming.
Key topics and technical requirements
- Digital Item structure and DIDL: Defines how content and associated metadata are packaged using MPEG-21 Digital Item Declaration (DIDL) constructs.
- File format and binary XML: References MPEG-21 file format and binary representations to enable interoperable storage and delivery.
- Metadata and identifiers: Standardizes metadata, Digital Item Identification (DII) and namespaces to ensure consistent content discovery and referencing.
- Security and IPMP: Integrates Intellectual Property Management and Protection (IPMP) components (licenses, keys, IPMP messages) for governed content delivery and rights management.
- Transport protocols: Specifies use of existing streaming protocols (MPEG-2 TS, RTP/UDP/IP) and profiles for streaming delivery.
- Device-to-device protocols: Covers access, domain and license management interactions among Content Provider Devices, Media Streaming Players, License Provider Devices and IPMP Tool Provider Devices.
- Conformance and reference software: Includes conformance testing guidance and reference software to support interoperable implementations.
- Informative examples and annexes: Multiple annexes provide schemas, detailed file format usage and application examples (IPTV, broadcasting, interactive multimedia).
Applications and who uses the standard
ISO/IEC 23000-5 is aimed at organizations building interoperable, standards-based streaming systems:
- Broadcasters and IPTV operators designing distribution formats and service metadata.
- Device manufacturers (set-top boxes, smart TVs, media streaming players) implementing compliant playback, DRM/IPMP and file handling.
- Streaming platform developers and middleware vendors implementing transport stacks, content packaging and license management.
- Content providers and aggregators packaging governed audio/video with metadata for multi-device distribution.
- DRM and licensing solution providers integrating IPMP components, keys and license protocols.
