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

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

Guidelines Creation Process

Develop Use Cases

• Technical Input• Ecosystem Input• Marketing Input• Prioritize

Generate Technical

Requirements

• Connectivity: Ethernet and 802.11

• Networking: All devices use IP protocols

Create Design

Guidelines

• Very specific details• Clarifies ambiguity

in a given standard• Identifies which

options to implement

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)
