Who Owns the Home Network?
2006 IEEE CCNC Conference Las Vegas MA1-1 Plenary
Panel Presentation

• Glen Stone
• Director, Standards Strategy
• Sony Electronics Inc.
• Chair DLNA Technical Committee

Agenda

• Overview of the Digital Living Network Alliance
  (DLNA)
• A CE perspective of the home network

The DLNA Vision
MOBILE MULTIMEDIA Entertainment, Personal
Pictures and Video, Services
BROADBAND Entertainment, E-Business, IPTV Services
MEDIA Pre-Recorded Content Personal Media
Consumers want their devices to work together and
share content
BROADCAST Services, Entertainment

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

5
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

6
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 SDOs to create required standards
• Examples
• CEA - OpenEPG, RemoteUI
• UPNP- QoS additions
• DVB - Media Formats

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 knowsit could be
• The device manufacturer
• The service provider
• The content provider
• Their neighbor
• Their son (in the case of my Mom)
