DLNA Confidential
The DLNA Vision
» Consumer friendly home networks
 Consists of IT and CE devices
 Content shared between devices from
different manufacturers
 A platform for the distribution of
personal content
 A platform for services and commercial
content

DLNA Confidential
The DLNA Approach
» Deliver design guidelines based on a
framework of open standards to ensure
interoperability between manufacturers’
devices
» Provide a common baseline of media
formats (to ensure interoperability at the
media level)
» Accelerate market acceptance through
compliance testing

DLNA Confidential
The DLNA Approach
» DLNA is not an SDO, DLNA does not create
standards
» Uses existing standards and Identifies when new
standards are required
» Liaisons with SDO’s to create required standards

Examples:
CEA - OpenEPG, RemoteUI
UPNP- QoS additions
DVB - Media Formats

selected media content, NOT
discoverable on the network
HTTP Client
HTTP

Interoperability Framework
Content Sharing
Framework
Media Formats
(Images, Audio, AV)
Media Transport
Complete set of components to deliver user
experience for sharing content
How media content is encoded and identified
for interoperability
How media content is transferred
(HTTP)
Media Management
(UPnP AV)
How media content is identified, managed,
and distributed
Device Discovery &
Control
(UPnP Device Arch)
How devices discover and control each other
Networking &
Connectivity
How devices physically connect together and
communicate
(IPv4, Ethernet, 802.11)

DLNA Conclusion
» Creation of guidelines was use case driven and filtered by
both marketing and technical criteria
» “Ownership” of the home network is out of scope of DLNA
» The very nature of the design guidelines insures all devices
are discoverable and accessible
» DLNA Interoperability Guidelines v1.0 addresses content
sharing interoperability between a DMS and DMP and is
available now at www.dlna.org

CE observations
»
The Consumer will attach a diverse array of devices to their home
network
 There cannot be one “owner”
»
They will get their content from multiple sources, based on:
 Cost
 Ease of acquisition
 Flexibility (usage rules)
»
Who will the consumer call when things go wrong?
 Who knows…it could be:
»
»
»
»
»
The device manufacturer
The service provider
The content provider
Their neighbor
Their son (in the case of my Mom)
