  • 1. Introduction  The Digital Living Network Alliance (DLNA) is a Non Profit Collaboration trade organization.  Established by Sony in June 2003.  Defines the Guidelines for Sharing of Digital Media between Multimedia Devices.  Guidelines are built upon existing public standards.  Guidelines specify a restricted ways of using standards to achieve interoperability.  They are private & available for some amount of fee.
  • 2. Overview  A wired and wireless interoperable network where digital content such as 1. Photos 2. Music 3. Videos can be seamlessly shared through 1. Personal computers (PCs), 2. Consumer Electronics(CE) , 3. Mobile devices. In and beyond the Home.  DLNA requires a Network.
  • 3. Backbone UPnP  DLNA uses Universal Plug and Play(UPnP) for : 1. Media management. 2. Discovery and control.  UPnP defines the type of Devices that DLNA supports.  It also Defines the mechanism for accessing MEDIA over network.  Thus called BackBone.  UPnP is set of networking protocols.  UPnP is used to seamlessly discover networked devices on network.
  • 4. Supported Devices  A wide Range of Consumer Electronics.  Latest TV’s come along the DLNA certified LOGO.  Various Mobile OS support DLNA.  Latest Audio Devices and Home Theater Systems.  Network Attached Servers.  Wireless Routers.
  • 5. Jpeg, Mp3, MPEG2, AVI,FLV,WMA UPnP AV 1.0 HTTP 1.0/1.1 IPv4 Protocol Suite UPnP Device Architecture 1.0 Wired :802.3i, 802.3u Wireless :802.11 b/g/n Media Format Device Discovery /Control, Media Management Media Transport Network Stack Network Connectivity DLNA Layered Architecture.
  • 6. Network Connectivity Layer: DLNA mechanism needs a network for sharing of multimedia data. The Network could be any wired or wireless Network. Network Stack : As the network is need , there has to be a protocol in through which data transferring/streaming should follow. It could be any protocol which is supported BY THE NETWORK through which Data is Streamed on the network. Media Transport: Basic mode of Media Transfer is HTTP.
  • 7. Device Discovery and Control Management  UPnP plays the Lead Role in this Work.  UPnP is Finds the Device .  UPnP also Controls and Manages the Media . Media Formats:  A Large number of Media Formats are supported by this architecture.  It supports all most all type of MULTIMEDIA formats
  • 8. UPnP  The Device model Used by DLNA is Derived From the UPnP Forum Fundamental Model.  UPnP Model Consist OF:  DEVICE: It is entity that provide a simple service. Eg a Mobile Phone.  SERVICES: They are the basic unit of control. They Provide Action and Maintain Status, example: A Mobile that supports a Data Transfer Service, Media Playback service.  Control Points: They are the entities that are capable of Discovering and also controlling the other devices.
  • 9. DLNA DEVICE MODELS  With development of the DLNA the Basic device model was extended so that the devices could them selves interact with each other to pass on digital data.  Previously, Control Point may be managing multiple devices, all interaction occur between and individual devices.  Now the control point configures the devices , as needed and initiates the flow of content, and gets out of the way.
  • 10. DLNA DEVICE MODELS DLNA INTEROPARABILITY GUIDELINES DEFINE 3 DEVICE CATEGORIES.  Home Network Device.  Mobile Handheld Devices.  Home Interoperability Devices.
  • 11. DLNA DEVICE MODELS The Home Network Device Category This Category has 5 Device Classes, that are in use at Home Network  Digital Media Server(DMS): It makes available digital media content.  Digital Media Player(DMP):It finds the content made available by DMS also provides a playback for the supported media.  Digital Media Renderer(DMR):Render or play the content made available by DMS.  Digital Media Controller(DMC):It sets up the Connection Between a DMS and DMR.  Digital Media Printer(DMPr):Provides Printing Services to DLNA Home Network.
  • 12. DLNA DEVICE MODELS The Mobile Handheld Device Category This Category share same usage models of HND Device Category but have different requirement for media format .  Mobile Digital Media Server(M-DMS):Offers and Distribute contents through mobile devices):Finds the content offered by a M-DMS and plays the content locally on the M-DMP.  Mobile Digital Media Downloader(M-DMD):Finds and Downloads the Contents exposed by an M-DMS and plays the content locally on the DMD.  Mobile Digital Media Controller(M-DMC):Finds the content offered by an M-DMS and match it to the rendering capabilities of a DMR, setting up a connection between server and renderer  Mobile Digital Media Up loader(M-DMU):Sends content to an M-DMS with upload Functionality.
  • 13. DLNA DEVICE MODELS The Home Infrastructure Device(HID) This category is made up of the two Device Classes.They allow HND’s and MHD’s to interoperate.  Mobile Network Connectivity Function(M-NCF): These Devices provide a bridging function between the MHD network connectivity and the HND network connectivity.  Media Interoperability Unit(MIU):Devices provide content transformation between required media formats for the HND Device Category and the MHD Device Category.
