Digital living network alliance (DLNA) home networked device interoperability guidelines. Link protection | Status: Withdrawn, Revised, Superseded

1 Scope This part of IEC 62481 specifies the DLNAlink protection guidelines, which are an extension of the DLNA guidelines. DLNAlink protection is defined as the protection of a content stream between two devices on a DLNA network from illegitimate observation or interception using the protocols defined within this standard. Content protection is an important mechanism for ensuring that commercial content is protected from piracy and illegitimate redistribution. Link protection is a technique that enables distribution of protected commercial content on a home network, thus resulting in greater consumer flexibility while still preserving the rights of copyright holders and content providers. The guidelines in this standard reference existing technologies for link protection and provide mechanisms for interoperability between different implementations as well as integration with the DLNA architecture. This standard is organized to align with the overall structure of IEC 62481‑1 and IEC 62481‑2.
