Introduction DLNA is an acronym for Digital Living Network Alliance. It is a capability in a device allowing it to talk to other devices with another DLNA device. It interconnects electronic devices within a zone. 3 4. primitive goal interconnect devices seamlessly. represents the content negotiation and sharing portion. 4 5. 5 The DLNA Vision 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 Fig.1 6. Why DLNA? Three main pools of electronic goods that prevail in today's world are Fig.2 6 7. Consumers wish to inter-operate in these 3 zones cross-industry organization of leading operators of these 3 islands - consumer electronics, computing industry and mobile devices. They provide a seamless environment 7 8. Fig.3 8 9. UPnP Origin of DLNA DLNA in its primitive form originated from UPnP Universal Plug and Play UPnP works on these basic schemes: Addressing Discovery Description Control notification Event Presentation 9 10. Networking and connectivity Advantages of using IP in digital home network: allows applications running over different media to communicate transparently. IP can connect every device in the home to the Internet IP connectivity is inexpensive. 10 11. Discovery Discovery includes device and service discovery. This takes into account - Discovering the presence and capabilities of other devices in the connected network. Control and interconnect with the discovered devices. The Service protocol used in DLNA is SSDP - Simple Service Discovery protocol. 11 12. Authentication & Authorization Authentication ,is the identification of user Authorization, level of access a particular authenticated user 12 13. All of this requires three basic components - a player, a server and a stream of data that are all compatible with each other. Fig.1 13 14. 14 Interoperability Framework Content Sharing Framework Networking & Connectivity (IPv4, Ethernet, 802.11) physically connect together and communicate Device Discovery & Control (UPnP Device Arch) devices discover and control Media Management (UPnP AV) identified, managed, and distributed Media Transport (HTTP) transferred Media Formats (Images, Audio, AV) encoded and identified for interoperability 15. Digital Rights Management (DRM) Content must be protected from unauthorized copying and use. Today, there are several DRM technologies available to device designers and content providers. 15 16. Use Cases Fig.5 16 17. 17 User is watching TV, wants to view pictures Fig.6 18. FUTURE MODIFICATIONS In the near future, digital homes will contain intelligent platforms which will manage and distribute rich digital content to rendering devices such as televisions and wireless monitors from devices such as digital cameras, camcorders and multimedia mobile phones. 18 19. Conclusion With growing demand for consumer goods, there is an equal rise in crave for interconnecting devices, be at home or office. The best aspect of DLNA is that it allows products from different manufacturers to talk to each other. With DLNA all leading CE companies are tied in a technological knot; there is interdependence, yet independence with their own products. 19 20.
