标准范围

ISO/IEC 29341-20-11:2017符合UPnP设备体系结构版本1.0[14]。这种服务类型支持对A/V设备的流媒体功能进行建模，并在设备之间绑定这些功能。能够根据UPnP AV体系结构发送或接收流的每个设备将有一个ConnectionManager服务实例。此服务为控制点提供了一种机制，用于:a） 在源/服务器设备和接收器/渲染器设备之间执行功能匹配，b） 查找有关网络中当前正在进行的传输的信息，c） 设置和断开设备之间的连接（当流媒体协议要求时）。ConnectionManager服务足够通用，可以正确地抽象不同类型的流机制，例如基于HTTP的流、基于RTSP/RTP的流和基于1394的流。ConnectionManager使控制点能够在进行连接时从物理介质互连技术中提取。这个词？此服务模板中使用的“流”指的是模拟和数字数据传输。

ISO/IEC 29341-20-11:2017 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.
