This part of IEC 62481 specifies the DLNA link protection guidelines, which are an extension
of the DLNA guidelines. DLNA link 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.
