Proprietary protocol

UPnP™ Remote UIInformal vocabulary "Remoting" - running application logic

and user interface on different devices.

"Protocol" - the format of peer-to-peer communication between the application and remote UI (not standardized by UPnP (not standardized by UPnP Remote UI)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 UISimple device definitions

UPnP Remote UI clientsclients: Have controls for connecting & administering

user interface sessions, May expose protocol-required information:

(display screen size, keyboard type, etc.)

UPnP Remote UI serversservers: 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

UPnP Remote UI serversservers advertise listings of remote-enabled UIs.

UPnP Remote UI control entitiescontrol entities match UI descriptions with remote clientclient capabilities and establish sessions. Note: communication protocol between UI and

client is not standardizednot standardized - vendors choose. Example protocols: MS RDP, Intel XRT,

EIA775, etc.
