1 Scope 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. This document 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.
