Full title and description

Digital living network alliance (DLNA) home networked device interoperability guidelines - Part 2: Media format profiles. IEC 62481-2:2017 defines DLNA Media Format Profiles for Audio, Image and AV media classes and introduces Profile ID values used to identify media collections in DLNA device interactions. This publication is the third edition and updates previous profiles to improve interoperability across DLNA device classes.

Abstract

IEC 62481-2:2017 specifies media format profiles that devices in DLNA home networks use to exchange and render audio, image and audiovisual content. The document assigns Profile ID values for media collections, clarifies mandatory and optional profile support for device classes (including updates for the CVP-2 Device Profile) and contains revisions intended to resolve interoperability issues identified since the prior edition. It is intended to be used together with the IEC 62481 series that defines device classes, architecture and protocols for DLNA-enabled home networks.

Scope

This part of IEC 62481 defines DLNA Media Format Profiles applicable to the DLNA device classes defined in IEC 62481-1-1:2017. It covers profile definitions for the Audio, Image and AV media classes and introduces Profile ID values that identify media collections. The standard specifies which codecs, container formats, resolution/bitrate ranges and metadata characteristics are required or permitted for each profile to enable consistent discovery, playback and interoperability among compliant home network devices.

Key topics and requirements

• Definition of media format profiles for Audio, Image and AV classes (file/container, codec, metadata constraints).
• Profile ID values for identifying and advertising media collections across DLNA devices.
• Mandatory and optional profile support rules for specific DLNA device profiles, including CVP-2 updates.
• Interoperability requirements and clarifications to resolve known compatibility issues from earlier editions.
• Normative referencing to related parts of the IEC 62481 series and conformance guidance for device implementers.

Typical use and users

Implementers of consumer and embedded multimedia devices (Digital Media Servers, Renderers, Players), firmware and application developers, system integrators, interoperability test laboratories and specification authors use this standard to ensure consistent media handling and compatibility in DLNA-enabled home networks. Device manufacturers rely on the profiles when selecting supported codecs/containers and reporting capabilities for network discovery and content sharing.

Related standards

IEC 62481-2:2017 is part of the IEC 62481 series of DLNA home network interoperability guidelines. Related parts include IEC 62481-1-1 and IEC 62481-1-2 (architecture and device classes/protocols), other parts covering remote user interfaces and additional device-specific guidelines. Implementers also commonly refer to DLNA technical guidelines and relevant UPnP specifications when applying this standard.

FAQ

Q: What is this standard?

A: IEC 62481-2:2017 is the DLNA home network interoperability guideline that defines media format profiles (Audio, Image, AV) and Profile ID values used by DLNA device classes to ensure consistent media exchange and playback.

Q: What does it cover?

A: It specifies the media formats, codec/container combinations, metadata and profile identifiers that devices should support or advertise for Audio, Image and AV content to achieve interoperability in DLNA networks, and clarifies mandatory/optional profile support for specific device profiles.

Q: Who typically uses it?

A: Device manufacturers, firmware and application developers, system integrators, test labs and standards authors working on home multimedia devices and services that implement DLNA interoperability.

Q: Is it current or superseded?

A: The document is the third edition published on 28 July 2017. It supersedes the 2013 edition and contains technical revisions intended to improve interoperability. Users should verify whether any later amendments or newer editions have been published before relying on the text for new designs.

Q: Is it part of a series?

A: Yes. IEC 62481-2:2017 is part of the IEC 62481 series of standards that cover DLNA home network device classes, architecture, protocols and additional profiles and guidelines.
