Description / Abstract:
Introduction
This service definition is compliant with the UPnP Device
Architecture version 1.0.
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:
Perform capability matching between source/server devices and
sink/renderer devices,
Find information about currently ongoing transfers in the
network,
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.
