Full title and description

ISO/IEC 14496-6:2000 — Information technology — Coding of audio-visual objects — Part 6: Delivery Multimedia Integration Framework (DMIF). This part of the MPEG‑4 family defines the Delivery Layer (DMIF) that enables transparent access to multimedia streams from interactive remote systems, broadcast media or storage media, and specifies the DMIF communication architecture, the DMIF‑Application Interface (DAI), URL semantics and a default signalling protocol (DDSP) for interactive scenarios.

Abstract

Specifies the Delivery Multimedia Integration Framework (DMIF) — a delivery layer for ISO/IEC 14496 that provides a uniform API and signalling framework so applications can access and control multimedia streams regardless of whether content is remote, broadcast or stored. Key elements include DMIF architecture, DAI, URL semantics, the DMIF Default Signalling Protocol (DDSP) and information flows for player access.

Scope

Defines the Delivery Layer for MPEG‑4 (ISO/IEC 14496) enabling applications to locate, access and control multimedia streams in a technology‑transparent way. The scope covers the DMIF communication architecture, the DMIF‑Application Interface (DAI) definition, URL semantics for stream location, the DMIF Default Signalling Protocol (DDSP) and variations that map to native network signalling, and the information flows required for player access to streams from remote interactive systems, broadcast carriers or storage media.

Key topics and requirements

• DMIF communication architecture: definition of the delivery-layer entities and interfaces required for transparent access to streams.
• DMIF‑Application Interface (DAI): API semantics and behaviour for applications to request and control multimedia delivery.
• URL semantics: standardized mechanisms to name and locate multimedia streams across delivery technologies.
• DMIF Default Signalling Protocol (DDSP): a signalling protocol for interactive remote scenarios and guidance for mapping to native network signalling.
• Information‑flow models: player and server interaction models for remote, broadcast and storage-based delivery.
• Interoperability requirements: behaviour and conformance guidance to promote transparent delivery across heterogeneous networks and storage media.

Typical use and users

Implemented by multimedia player developers, streaming server and gateway vendors, network protocol engineers, system integrators and standards implementers who need a uniform delivery-layer interface for MPEG‑4 content across different delivery technologies. Also used by researchers and product teams designing end‑to‑end multimedia delivery systems where transparent access and signalling interoperability are required.

Related standards

Part of the ISO/IEC 14496 (MPEG‑4) series; closely related to Parts 1 (Systems), 2 (Visual), 3 (Audio), 4 (Conformance testing) and 5 (Reference software). DMIF functionality is complementary to carriage and transport parts (for example Part 8 for carriage over IP) and to scene/application parts (such as Part 11). The MPEG‑4 parts list and relationships are documented in MPEG‑4 overview material.

FAQ

Q: What is this standard?

A: ISO/IEC 14496‑6:2000 is the MPEG‑4 specification for the Delivery Multimedia Integration Framework (DMIF), defining a delivery layer to enable transparent access to multimedia streams across remote, broadcast and storage delivery technologies.

Q: What does it cover?

A: It covers DMIF architecture, the DMIF‑Application Interface (DAI), URL semantics to locate streams, the DMIF Default Signalling Protocol (DDSP) and information‑flow models for player access to remote, broadcast and stored streams.

Q: Who typically uses it?

A: Multimedia player and streaming server developers, network and protocol engineers, system integrators and standards implementers who require a consistent delivery‑layer interface for MPEG‑4 content. Researchers and product teams building end‑to‑end delivery solutions also reference this part.

Q: Is it current or superseded?

A: Edition 2 (published December 2000) is the published version; an earlier 1999 edition was withdrawn. ISO’s records show the part has been maintained through periodic reviews; consult the ISO catalog for the latest formal lifecycle status if you need current confirmation.

Q: Is it part of a series?

A: Yes — it is Part 6 of the ISO/IEC 14496 (MPEG‑4) series and is designed to work with other MPEG‑4 parts (Systems, Visual, Audio, Conformance, Reference Software, Carriage, Scene Description, etc.).

Q: What are the key keywords?
