What is BS IEC 62481‑2 - DLNA home networked device interoperability about?
BS IEC 62481‑2 discusses digital living network alliance (DLNA) home networked device interoperability. BS IEC 62481‑2, the DLNA guidelines describe DLNA Media Format Profiles applicable to the DLNA Device Classes defined in IEC 62481-1-1:2017. Media Format Profiles are defined for each of the following Media Classes: Audio, Image, and AV. In addition, Profile ID values that identify media collections are also introduced.
The Profile ID is exposed in a server's Content Directory Service (CDS) to signal potential networked players or renderers the existence of a content item with particular coding and compression features are defined precisely by the item's Profile ID.
Who is BS IEC 62481‑2 - DLNA home networked device interoperability for?
BS IEC 62481‑2on DLNA home networked device interoperability is useful for:
- Smart home device manufacturers
- Developers of smart home device
Why should you use BS IEC 62481‑2- DLNA home networked device interoperability?
Formats alone, however, include as part of their specifications, multiple parameters, features, and tools which are used in a myriad of combinations to generate content binaries. BS IEC 62481‑2 introduces the notion of Mandatory Media Format Profiles, supported by all devices, as a means to provide baseline content interoperability in the home.
BS IEC 62481‑2 provides a comprehensive list of all Media Format Profiles defined for this version of the Media Format guidelines. The description includes the Profile ID values as well as a brief summary of features and usage scenarios.
What’s changed since the last update?
BS IEC 62481‑2:2017 supersedes IEC 62481-2:2013, which is withdrawn. BS IEC 62481‑2:2017 includes some technical changes with respect to IEC 62481-2:2013.
These include:
- Removal of optional media format profiles for Audio and AV content
- Addition of mandatory media format profiles for the CVP-2 Device Profile
- Includes updates to resolve interoperability issues.
