Overview
IEC 62481-5:2017 defines the DLNA Device Profiles used to ensure interoperable home networking for consumer media devices. Part 5 of the IEC 62481 series specifies what a Device Profile is (a collection of DLNA capabilities and features) and lists the mandatory guidelines a device must meet to claim compliance. This second edition (2017) replaces the 2013 edition and updates the Commercial Video Profile (CVP) set - CVP-NA-1 was removed and CVP-2 was added - reflecting technical revisions for commercial content delivery in home networks.
Key Topics and Technical Requirements
- Device Profile definitions: Formal rules for grouping DLNA capabilities into profiles that a device must fully implement to be compliant.
- Commercial Video Profiles (CVPs): Extensions for distributing commercial content from service providers and multichannel video programming distributors into DLNA home networks. CVPs address regional requirements.
- Media Format Profiles: Mandatory media format profiles and link-protected profiles for regions (e.g., North America and Europe) and how they are applied to device classes.
- Architecture and Protocol Guidelines:
- Baseline client and baseline server expectations for DLNA clients/servers.
- Updates to HTTP media transport guidelines for streaming transfers.
- Quality of Service (QoS) related updates for media streaming.
- Device discovery and control: Conventions for discovering, launching, and controlling DLNA services in the home.
- HTML5 Remote UI (RUI-H): Guidelines for web-based remote user interfaces and service presentation/launch from client devices.
- Authentication and Link Protection: Authentication examples, TLS-based exchanges, and guidance for protected commercial streams.
- 3‑D Media Rendering: Rendering considerations for 3-D media content.
- Informative annexes: Architecture diagrams, deployment scenarios (in-home and cloud), authentication examples, and a client implementer’s guide.
Applications and Who Uses This Standard
IEC 62481-5:2017 is used by:
- CE manufacturers (smart TVs, media players, set‑top boxes) implementing DLNA Device Profiles.
- Software developers building DLNA-compliant clients, servers, and remote UIs.
- Service providers and MVPDs integrating commercial video delivery into home networks.
- System integrators and testers performing interoperability and conformity testing.
- Product managers and architects designing home multimedia ecosystems that require DLNA-compliant streaming, authentication, and link protection.
Practical outcomes include consistent device behavior across vendors, reliable delivery of commercial and consumer media, and streamlined integration of HTML5-based remote UIs.
