Title Digital living network alliance (DLNA) home networked device interoperability guidelines - Part 3: Link protection
Project Number 24238
Abstract/Scope IEC 62481-3:2013(E) 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 part of IEC 62481. It references existing technologies for Link Protection and provide mechanisms for interoperability between different implementations as well as integration with the DLNA architecture. This second edition cancels and replaces the first edition published in 2010 and constitutes a technical revision. It includes the following changes: - includes variable play (trick mode) support; - includes updates to resolve interoperability issues.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
