DLNA: Interoperability at All Layers

DTCP/IP (mandatory) WMDRM-ND (optional)

How commercial content is protected on the Home Network

Link Protection

MPEG2, MPEG4, AVC/H.264, LPCM, MP3, AAC LC, JPEG, XHTML-Print+ optional formats

How media content is encoded and identified for interoperability

Media Formats

HTTP (mandatory) RTP (optional)Quality of Service

Media Transport

How media content is transferred

UPnP AV 1.0UPnP Print Enhanced 1.0

How media content is identified, managed, and distributed

Media Management

UPnP Device Architecture 1.0

How devices discover and control each other

Discovery & Control

IPv4 Protocol Suite

IP Networking

How wired and wireless devices physically connect and communicate

Mandatory Ethernet 802.3 or Wi-Fi 802.11, Optional: MOCA

Connectivity

dlna functions
DLNA Functions
  • Discover

Find devices on the network without configuration and figure out which capabilities they offer

  • Browse

Look through content, sorted in various ways

  • Search

Find specific content on a device

  • Stream

Send AV content over the network in real-time

  • Serve

Announce a directory of content to the network

  • Print

Send content to a network attached printer

  • Control

Use the network to change the status of a device

  • Upload

Send any content to a server

  • Download

Receive and store any content

  • Transcode

Change the resolution or format of content so that it can be rendered correctly on a device

  • Quality of Service (QoS)

Prioritize network traffic, so that if the network becomes overloaded, the lowest priority traffic is dropped first

device category and device class
Device Category and Device Class
  • Device Categories:
    • Device classes sharing common set of system usages
    • Mobile Handheld Devices (MHD): Mobile devices that leave the home and which have limitations on power, bandwidth, etc
    • Home Network Devices (HND): Networked media devices that primarily reside in the home or which have capabilities on par with such devices
    • Home Infrastructure Devices (HID): Devices which interconnect DLNA devices
    • A device may be in multiple device categories
  • Device Class:
    • DLNA certifiable entity that supports a defined system usage
    • Has requirements at all layers of the DLNA framework/architecture
    • A product may support one of more device classes
