标准摘要
[中文适用范围]： 本部分规定了使用UPnP（通用即插即用）设备架构的家庭网络环境中音频视频(AV)设备的控制协议和交互模型。其目标是通过提供一致且可扩展的方式来实现AV设备之间的互操作性，包括媒体服务器、媒体渲染器以及控制点的交互。 本部分的范围不包括以下内容： 1. 详细描述每个具体UPnP AV服务的实现细节。 2. 规定物理接口或介质的具体要求。 [外文原描述]： ISO/IEC 29341-20-1:2017 describes the overall UPnP AV Architecture, which forms the foundation for the UPnP AV Device and Service templates. The AV Architecture defines the general interaction between UPnP control points and UPnP AV devices. It is independent of any particular device type, content format, and transfer protocol. It supports a variety of devices such as TVs, VCRs, CD/DVD players/jukeboxes, settop boxes, stereos systems, MP3 players, still-image cameras, camcorders, electronic picture frames (EPFs), and the PC. The AV Architecture allows devices to support different types of formats for the entertainment content (such as MPEG2, MPEG4, JPEG, MP3, Windows Media Architecture (WMA), bitmaps (BMP), NTSC, PAL, ATSC, etc.) and multiple types of transfer protocols (such as IEC-61883/IEEE-1394, HTTP GET, RTP, HTTP PUT/POST, TCP/IP, etc.). The following clauses describe the AV Architecture and how the various UPnP AV devices and services work together to enable various end-user scenarios.
