What is BS IEC 62481‑4 - DLNA home networked device interoperability about?
BS IEC 62481‑4 discusses digital living network alliance (DLNA) home networked device interoperability. BS IEC 62481‑4, the DLNA guidelines, specifies DLNA guidelines for DRM Interoperability Solutions (DIS), are defined as methods to enable the secure transfer and use of protected commercial content between different implementations on network media devices. This content could be protected by different content protection technologies. In BS IEC 62481‑4, they are referred to as DRMs.
The guidelines are not intended to replace or disable other interoperability mechanisms that could already be in place, for example, DLNA Link Protection guidelines stated in IEC 62481-3:2017 or mechanisms provided by underlying DRMs.
Who is BS IEC 62481‑4 - DLNA home networked device interoperability for?
BS IEC 62481‑4 on DLNA home networked device interoperability is useful for:
- Smart home device manufacturers
- Developers of smart home device
Why should you use BS IEC 62481‑4 - DLNA home networked device interoperability?
The digital home vision integrates the Internet, mobile, and broadcast networks through a seamless, interoperable network, which will provide a unique opportunity for manufacturers and consumers alike. In order to cater to this need, a common set of industry design guidelines is needed that allows vendors to participate in a growing marketplace, leading to more innovation, simplicity, and value for consumers.
BS IEC 62481‑4 serves that purpose and provides vendors with the information needed to build interoperable networked platforms and devices for the digital home. BS IEC 62481‑4 defines the usage guidance for the DTCP-IP DLNA DIS technology. For convenience, the term "DTCP-IP DIS" is used to mean the DTCP-IP technology for a DLNA DIS.
