信息技术 - UPnP设备架构 - 第28-1部分:多屏幕设备控制协议 - 多屏架构

[中文适用范围]： 多屏/副屏解决方案正在迅速发展。然而，每个解决方案都是特定供应商的专有垂直领域。因此用户的期望没有得到满足： 跨供应商的无缝互操作性。 第二屏集成使用的功能，而不是100多个不同的应用程序。UPnP Multi-Screen 设备控制点协议 (DCPs) 提供了一个开放接口以实现设备和应用程序之间的这种互操作性，即支持时敏和交互式服务（包括特定于实现的应用程序）在各种显示设备之间。 本文件描述了多屏总体架构，该架构构成了 UPnP 多屏设备和服务模板的基础。多屏架构定义了 UPnP 控制点与根据 UPnP 多屏 DCP 定义的 UPnP 设备之间的通用交互。 [外文原描述]： 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.
