BS 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，并绑定 设备之间的这些功能。每个能够发送或接收流的设备 根据UPnP AV架构，将有一个ConnectionManager服务实例。此服务为控制点提供了一种机制: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）设置和拆除设备之间的连接（当流媒体需要时） 协议）。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、RTSP/RTP- 基于和基于1394 流动。ConnectionManager允许控制点从物理介质互连中提取 建立联系时的技术。“流”这个词？此服务模板中使用的是 模拟和数字数据传输。交叉引用:IEC 61883-4:2004IEC 61883-3:2004IEC 61883-1:2008IEC 61883-2:2004ISO/IEC 14977:1996IEC 61883-5:2004IETF RFC 2030IEC-PAS 61883IETF RFC 3550IEEE-P1733IETF RFC 1341IETF RFC 1305IEEE P802。1 SIETF RFC 4122IETF RFC 3986IETF RFC 1321IETF RFC 2045IETF RFC 4078IETF RFC 1738IETF RFC 3339IETF RFC 2326IETF RFC 2119ISO/IEC 21000-2:2003购买本文件时提供的所有现行修订均包含在购买本文件中。

BS 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.Cross References:IEC 61883-4:2004IEC 61883-3:2004IEC 61883-1:2008IEC 61883-2:2004ISO/IEC 14977:1996IEC 61883-5:2004IETF RFC 2030IEC-PAS 61883IETF RFC 3550IEEE-P1733IETF RFC 1341IETF RFC 1305IEEE P802.1ASIETF RFC 4122IETF RFC 3986IETF RFC 1321IETF RFC 2045IETF RFC 4078IETF RFC 1738IETF RFC 3339IETF RFC 2326IETF RFC 2119ISO/IEC 21000-2:2003All current amendments available at time of purchase are included with the purchase of this document.
