20 Home Network Devices Digital Media Server (DMS) These devices store content and make it available to networked digital media players (DMP) and digital media renderers (DMR). Some digital media servers can also help protect your content once stored. Examples: PCs and network attached storage (NAS) devices.

21 Home Network Devices Digital Media Player (DMP) These devices find content on digital media servers (DMS) and provide playback and rendering capabilities. Examples: TVs, stereos and home theaters, wireless monitors and game consoles.

22 Home Network Devices Digital Media Renderer (DMR) These devices play content received from a digital media controller (DMC), which will find content from a digital media server (DMS). Examples: TVs, audio/video receivers, video displays and remote speakers for music.

23 Home Network Devices Digital Media Controller (DMC) These devices find content on digital media servers (DMS) and play it on digital media renderers (DMR). Examples: Internet tablets, Wi-Fi® enabled digital cameras and personal digital assistants (PDA).

24 Home Network Devices Digital Media Printer (DMPr) These devices provide printing services to the DLNA home network. Generally, digital media players (DMP) and digital media controllers (DMC) with print capability can print to DMPr. Examples: networked photo printers and networked all-in-one printers.

25 Mobile Handheld Devices Mobile Digital Media Server (M-DMS) These wireless devices store content and make it available to wired/wireless networked mobile digital media players (M-DMP), digital media renderers (DMR) and digital media printers (DMPr). Examples: mobile phones and portable music players.

26 Mobile Handheld Devices Mobile Digital Media Player (M-DMP) These wireless devices find and play content on a digital media server (DMS) or mobile digital media server (M-DMS). Examples: mobile phones and mobile media tablets designed for viewing multimedia content.

27 Mobile Handheld Devices Mobile Digital Media Uploader (M-DMU) These wireless devices send (upload) content to a digital media server (DMS) or mobile digital media server (M-DMS). Examples: digital cameras and mobile phones.

28 Mobile Handheld Devices Mobile Digital Media Downloader (M-DMD) These wireless devices find and store (download) content from a digital media server (DMS) or mobile digital media server (M-DMS). Examples: portable music players and mobile phones.

29 Mobile Handheld Devices Mobile Digital Media Controller (M-DMC) These wireless devices find content on a digital media server (DMS) or mobile digital media server (M-DMS) and send it to digital media renderers (DMR). Examples: personal digital assistants (PDAs) and mobile phones.

30 Home Infrastructure Devices (HID) 2-Box Pull System Usage Interaction Model Between Device Categories

31 Mobile Network Connectivity Function (M-NCF) These devices provide a bridge between mobile handheld device (MHD) network connectivity and home network device (HND) connectivity.

32 Media Interoperability Unit (MIU) These devices provide content transformation between required media formats for home network and mobile handheld devices.

35 Device Capabilities A Push Controller (+PU+) pushing its local content to a DMR. A Printing Controller-1 (+PR1+) controlling a DMPr to print image content. A Printing Controller-2 (+PR2+) controlling a DMPr to print image content. An Upload Controller (+UP+) sending content to a DMS or M-DMS with upload functionality. A Download Controller (+DN+) downloading content from a DMS or M-DMS to itself.

36 2-Box Pull System Usage 1. Invoke UPnP actions to browse and select content. 2. Request the content for playback. 3. Transport the content to the DMP or the M-DMP.

37 2-Box Push System Usage 1. Invoke UPnP actions to set up a playback session. 2. Request the content for playback. 3. Transport the content to the DMR.

38 3-Box System Usage 1. Invoke UPnP actions to browse and select content. 2. Invoke UPnP actions to verify that the DMR has the capability to render the selected content and then set up a connection for the selected content between the DMR and the DMS or the M-DMS. 3. Request the content for playback. 4. Transport the content to the DMR.

39 2-Box Printing System Usage 1. Invoke UPnP actions to the DMPr to initiate the print job by providing the URL to the XHTML-Print document. 2. The DMPr acquires the XHTML-Print document from the Printing Controller The DMPr requests the Image content from the Printing Controller The Printing Controller 1 responds with the Image content.

40 3-Box Printing System Usage 1. Invoke UPnP actions to browse and select image content. 2. Get the URLs for the selected image content and reference the URLs in the XHTML-Print document. 3. Invoke UPnP actions on a DMPr to initiate the print job by providing the URL to the XHTML- Print document. 4. The DMPr acquires the XHTML-Print document from the Printing Controller The DMPr requests the Image content from the DMS or M-DMS. 6. The DMS or M-DMS responds with the Image content.

41 Download System Usage 1. Invoke UPnP actions to find content to download. 2. Request the content that needs to be downloaded. 3. Transport content to the Download Controller or the M-DMD.

42 Upload System Usage 1. Invoke UPnP actions to create a CDS entry for the content to be uploaded. 2. Transport the content being uploaded to the DMS or the M-DMS.

44 What is Universal Plug and Play Technology? Provides invisible home networking Architectural framework for self-configuring, self- describing devices Leverages existing Internet technologies Enables dynamic peer-to-peer networking Key to making the connected home experience Affordable, mainstream reality for users Significant opportunity for the industry

45 Audio & Video Example Media Server 1.Discovery of devices and services 2.Browsing of content 3.Selection of streaming protocols 4.Streaming and Playback (out of band*) CDs, DVDs, Flash Cards Local Content End User Benefits: Discover A/V content on all UPnP devices and PCs and share across home network Stream content easily from any device to any device on home network Control point offers rich, easy to use interface for creating and managing media Supports DVD, CD, play list, photo album, live broadcast, etc Manufacturer and Service Provider Benefits: Highly extensible – any data type, any transfer protocol, any combination of server, render, and control point Highly scalable – ultra low resource devices (cameras, EPF) up to high-end servers (PCs, media servers, Internet, broadcasts, PVR). Stereo TV Picture Frame Remote Control * Out of band = not UPnP Constrained UPnP devices added to network and discovers media content

46 The UPnP Forum UPnP – Universal Plug and Play is a technology intended for smart homes, small offices and other types of local area networks. It was originally created by Microsoft Corporation in UPnP is now under the control of the UPNP forum ( an independent organization with over 770 members.

47 The UPnP Forum Non-profit industry standards consortium Framework for efficient industry collaboration Develop Device Control Protocols (DCPs) for a broad class of devices Provide for the test qualification and interoperability of UPnP devices A market development organization Promotion, evangelism and marketing activities to promote UPnP brand recognition worldwide UPnP Forum
