3. DLNA Confidential 2 The DLNA Vision Consumers want their devices to work together and share content Consumers want their devices to work together and share content MEDIA Pre-Recorded Content Personal Media MOBILE MULTIMEDIA Entertainment, Personal Pictures and Video, Services BROADCAST Services, Entertainment BROADBAND Entertainment, E-Business, IPTV Services Consumers want their devices to work together and share content

4. DLNA Confidential 3 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 » 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. DLNA Confidential 4 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 » 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. DLNA Confidential 5 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 » 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

DLNA Confidential 11 Interoperability Framework Content Sharing Framework Networking & Connectivity (IPv4, Ethernet, 802.11) How devices physically connect together and communicate Device Discovery & Control (UPnP Device Arch ) How devices discover and control each other Media Management (UPnP AV) How media content is identified, managed, and distributed Media Transport (HTTP) How media content is transferred Media Formats (Images, Audio, AV) How media content is encoded and identified for interoperability Complete set of components to deliver user experience for sharing content

13. DLNA Confidential 12 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.orgwww.dlna.org » 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.orgwww.dlna.org

14. DLNA Confidential 13 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) » 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)
