ISO/IEC 931-1-1:1:2017描述了整个UPnP AV架构，它为UPnP AV设备和服务模板奠定基础。AV架构定义了UPnP控制点和UPnP AV设备之间的一般交互。它独立于任何特定的设备类型、内容格式和传输协议。它支持多种设备，如电视、VCR、CD/DVD播放器/自动唱机、机顶盒、立体声系统、MP3播放器、静止图像照相机、摄像机、电子相框（EPF）和PC。AV体系结构允许设备支持不同类型的娱乐内容格式（如MPEG2、MPEG4、JPEG、MP3、Windows Media Architecture（WMA）、位图（BMP）、NTSC、PAL、，ATSC等。 )以及多种类型的传输协议（如IEC-61883/IEEE-1394、HTTP GET、RTP、HTTP PUT/POST、TCP/IP等）。以下条款描述了AV架构，以及各种UPnP AV设备和服务如何协同工作，以实现各种最终用户场景。

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.
