BS ISO/IEC 29341-28-1:2017: 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.All current amendments available at time of purchase are included with the purchase of this document.
