Connectivity


Dlna functions l.jpg
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 l.jpg
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
