CSA Preface
Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).
For brevity, this Standard will be referred to as “CSA ISO/IEC 29341-28-1” throughout.
At the time of publication, ISO/IEC 29341-28-1:2017 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC.
The International Standard was reviewed by the CSA TCIT under the jurisdiction of the CSA Strategic Steering Committee on Information and Communications Technology and deemed acceptable for use in Canada. From time to time, ISO/IEC may publish addenda, corrigenda, etc. The TCIT will review these documents for approval and publication. For a listing, refer to the Current Standards Activities page at standardsactivities.csagroup.org. This Standard has been formally approved, without modification, by the Technical Committee and has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
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.
