Overview
ISO/IEC 29341-29-10:2017 defines the ApplicationManagement (AMS) networked service, version 2, as part of the UPnP Device Architecture series. This Level‑2 multiscreen device control protocol specifies how UPnP-enabled devices manage applications and inter-application communications across multiple display devices (called Screen Devices) and Screen Control Points. The standard is compliant with UPnP Device Architecture 1.0 and may be implemented as a required service on Screen Devices or as an add‑on on other UPnP devices.
Key technical topics and requirements
- Service model and type: Formal service type definition for ApplicationManagement v2 consistent with UPnP conventions.
- State variables: Standard state variables used for discovery and control (examples in the standard include FeatureList, AppInfoList, RunningAppList, TransitioningApps).
- Actions / API: Defined control actions for application lifecycle and management, such as:
- Discovery: GetFeatureList(), GetAppIDList(), GetAppInfoByIDs()
- Lifecycle: StartAppByID(), StartAppByURI(), StopApp()
- Installation: InstallAppByID(), InstallAppByURI(), UninstallApp(), GetInstallationStatus()
- Connectivity: GetAppConnectionInfo(), ConnectApptoApp(), DisconnectApptoApp(), GetCurrentConnectionInfo()
- Eventing and moderation: Event notification model and moderation rules to control event frequency and payloads.
- Security and roles: Defined SECURITY feature, roles and permission mappings for actions, and common error codes for access control.
- XML service description & testing: Complete XML service description and test guidance to enable interoperability and conformance testing.
- Error handling: Tables of error codes and mapping for common and action-specific failures.
Practical applications and who uses this standard
- Application: Enables coordinated, time-sensitive and interactive applications across multiple screens - e.g., multiscreen streaming, second-screen interactivity, digital signage orchestration, conference room displays, and smart-home multi-display scenarios.
- Users:
- Device manufacturers building UPnP Screen Devices or display products
- Middleware and platform developers implementing multiscreen application management
- Application developers integrating app lifecycle and inter-app communication across displays
- Systems integrators and quality engineers using the XML service description and test cases for interoperability
- Benefits: Standardized control APIs, consistent eventing, and defined security roles improve interoperability and faster integration across vendors.
