3. 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.

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

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

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.

12. Authentication & Authorization
 Authentication ,is the identification of user
 Authorization, level of access a particular
authenticated user

13. All of this requires three basic components - a player, a server and a
stream of data that are all compatible with each other.

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.

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.

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.
