UPnP
abbreviation for Universal Plug and Play (UPnP)
UPnP is an extension of the Microsoft Plug & Play standard
that allows devices to network globally and to exchange
services—without a central server or computer.
UPnP allows devices from all kinds of manufacturers (ste-
reo systems, routers, printers, house controls) to be con-
trolled via an IP-based network, with or without central
control through a gateway. It is based on a number of
standardized network protocols and data formats. Ex-
pressed simplistically, devices can communicate with
each other automatically using UPnP to exchange informa-
tion.
Today the UPnP forum specifies the UPnP standard and
certifies devices that are compliant with the standard.
UPnP AV
abbreviation for Universal Plug and Play Audio/Video
UPnP AV is a UPnP specification for the interaction be-
tween the media server, playback devices and devices
controlling the streaming of audio and video data within
networks. Media servers are devices that make audio and
video data available upon request. Playback devices (tele-
vision, stereo system, streaming clients) render the audio
and video data. Control devices are remote controls.
