UPnP Remote UIExample 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.

• A home automation/security system displays
  controls and alerts on many UI devices

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

UPnP Remote UI Basic DCP

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

UPnP Remote UIAdvanced DCP - MIRROR

• Copy a UI currently connected to RUI Client A to
  RUI Client B
• Call GetCurrentConnections() on A
• Call Connect() on B using the UI info from A
• Fails
• When multiple connections to the same UI are not
  supported
• When UI on A is not compatible with B

12
UPnP Remote UIAdvanced DCP - MOVE

• Move a UI running on RUI client A to RUI client B
• Call GetCurrentConnections() on A
• Call GetCurrentConnections() on B - get
  ConnectionsUpdateID value
• Calls Disconnect() on A
• Call Connect() on B using ConnectionsUpdateID
  value for client B, along UI info from A
• Fails when ltlifetimegt 0. Lifetime may be
  extended with SetUILifetime()

13
UPnP Remote UIAdvanced DCP - RECONNECT

• Reconnect to a disconnected UI.
• Call GetCompatibleUIs() action on the RUI Server
  and find the UI.
• Call Connect() on a designated RUI Client device
  to reconnect to the original, targeted UI.
• Fails when ltlifetimegt 0. Lifetime may be
  extended with SetUILifetime().

• Compile write up for usage of specific remoting
  protocols
