Specification

The DLNA Certified Device Classes are separated as follows:

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). Examples include PCs and network-attached storage (NAS) devices.
  • Digital Media Player (DMP): These devices find content on digital media servers (DMS) and provide playback and rendering capabilities. Examples include TVs, stereos and home theaters, wireless monitors and game consoles.
  • 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 include TVs, audio/video receivers, video displays and remote speakers for music.
    • Note: it is possible for a single device (e.g. TV, A/V receiver, etc.) to function both as a DMR (receives "pushed" content from DMS) and DMP ("pulls" content from DMS)
  • Digital Media Controller (DMC): These devices find content on digital media servers (DMS) and play it on digital media renderers (DMR). Examples include Internet tablets, Wi-Fi enabled digital cameras and personal digital assistants (PDAs).
  • 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 include networked photo printers and networked all-in-one printers

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 include mobile phones and portable music players.
  • 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 include mobile phones and mobile media tablets designed for viewing multimedia content.
  • 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 include digital cameras and mobile phones.
  • 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 include portable music players and mobile phones.
  • 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 include personal digital assistants (PDAs) and mobile phones.

Home Infrastructure Devices

  • Mobile Network Connectivity Function (M-NCF): These devices provide a bridge between mobile handheld device network connectivity and home network connectivity.
  • Media Interoperability Unit (MIU):These devices provide content transformation between required media formats for home network and mobile handheld devices.
