如今，多屏/二屏解决方案正在激增。然而，每个都是特定供应商的专有垂直线。因此，用户的期望没有得到满足: -跨供应商的无缝互操作性。 -第二屏集成使用的能力，而不是100个不同的应用程序。 UPnP多屏幕设备控制协议（DCP）提供了一个开放的接口，以实现设备和应用程序之间的这种互操作性，即在各种显示设备之间实现时间敏感和交互式服务，包括特定于实现的应用程序。 ISO/IEC 931-1-81-1:2017描述了整个多屏幕体系结构，这为UPnP的多个基础奠定了基础。 屏幕设备和服务模板。多屏幕体系结构定义了UPnP控制点和UPnP多屏幕DCP定义的UPnP设备之间的一般交互。

Today multi-screen/second-screen solutions are proliferating. However, each is a proprietary vertical for particular vendor(s). Therefore users expectations aren't being met: - Seamless interoperability across vendors. - Ability for second screen integrated usages rather than 100s of different apps. The UPnP Multi-Screen Device Control Protocols (DCPs) provide an open interface to enable this interoperability between devices and applications, i.e. enable time-sensitive and interactive services, including implementation-specific applications, among various display devices. ISO/IEC 29341-28-1:2017 describes the overall Multi-Screen Architecture, which forms the foundation for the UPnP Multi-Screen Device and Service templates. The Multi-Screen Architecture defines the general interaction between UPnP control points and UPnP devices defined by the UPnP Multi-Screen DCPs.
