NBN ISO/IEC 29341-20-11:2021

This service definition is compliant with the UPnP Device Architecture version 1.0 [14].
This service-type enables modeling of streaming capabilities of A/V devices, and binding of
those capabilities between devices. Each device that is able to send or receive a stream
according to the UPnP AV Architecture will have 1 instance of the ConnectionManager service.
This service provides a mechanism for control points to:
a) Perform capability matching between source/server devices and sink/renderer devices,
b) Find information about currently ongoing transfers in the network,
c) Setup and teardown connections between devices (when required by the streaming
protocol).
The ConnectionManager service is generic enough to properly abstract different kinds of
streaming mechanisms, such as HTTP-based streaming, RTSP/RTP-based and 1394-based
streaming.
The ConnectionManager enables control points to abstract from physical media interconnect
technology when making connections. The term ‘stream’ used in this service template refers
to both analog and digital data transfer.
