UPnP TM Remote UI Markus Wischy Senior Architect Siemens

UPnP™ Remote UI Example user scenarios A home PC remotely displaying application user interfaces on the living room television. A DVR/set top box displays control menus on all televisions in the home.

UPnP™ Remote UI Example user scenarios A home automation/security system displays controls and alerts on many UI devices Home Server UPnP events & control actions UPnP Remote UI Bridge Bridge Proprietary protocol

UPnP ™ Remote UI Informal vocabulary "Remoting" - running application logic and user interface on different devices. (not standardized by UPnP Remote UI) "Protocol" - the format of peer-to-peer communication between the application and remote UI (not standardized by UPnP Remote UI). "Remote UI client device" - where the UI is executed/displayed. "UI server" - exposes lists of remote-able applications and status of running applications.

UPnP ™ Remote UI Simple device definitions clients UPnP Remote UI clients:  Have controls for connecting & administering user interface sessions,  May expose protocol-required information: (display screen size, keyboard type, etc.) servers UPnP Remote UI servers:  Expose lists of remote-able UIs,  Expose status of instantiated UIs and UI sessions,  Have controls for destroying instantiated, unconnected UI’s

UPnP ™ Remote UI Basic DCP servers UPnP Remote UI servers advertise listings of remote-enabled UIs. control entities client UPnP Remote UI control entities match UI descriptions with remote client capabilities and establish sessions. not standardized  Note: communication protocol between UI and client is not standardized - vendors choose.  Example protocols: MS RDP, Intel XRT, EIA775, etc.
