DLNA Guidelines
March-2014
(Revised 20141215)
Part 1-1: Architectures and Protocols
An Industry Guide for
Building Interoperable
Platforms, Devices,
and Applications
Fulfilling the promise of the digital home requires a cross-industry effort to develop and promote a
common industry framework for interoperability. This industry framework is expressed through the
DLNA Guidelines document that has been developed to provide Consumer Electronic, Mobile
Device and PC companies with the information needed to build interoperable platforms, devices,
and application for the digital home.
