Abstract: Methods and apparatus are provided for externally managing control target devices such as computer systems, cameras, recorders, etc., in an effective and secure manner. In particular examples, an external desktop agent is connected to a computer system. Remote desktop agent software need not be installed on the computer system. The external desktop agent receives commands such as keyboard and mouse commands from a control computer over a mechanism such as a bi-directional network. To provide security, the external desktop agent does not directly connect to the computer system over an interface such as universal serial bus (USB) but instead provides a PS/2 interface that connects to the computer system through a standard PS/2 to USB adapter. PS/2 does not allow bi-directional command signaling and does not provide file level access to potentially sensitive computer system data.

Abstract: Methods and apparatus are provided for efficiently and intelligently communicating characteristic information in video graphics switcher environments. An intelligent video graphics switcher obtains display device characteristic information associated with multiple display devices and maintains updated characteristic information. When an event such as a connection/disconnection or switching event occurs between the video graphics switcher and a display device, the characteristic information is communicated to an appropriate host by triggering a connection/disconnection event with the host.

Abstract: Methods and apparatus are provided for efficiently controlling source computers connected to a display system. A control computer is connected to one or more source computers and video output is shown on a display system. A mouse and associated input devices may operate in video processor mode or source computer mode based on mouse x-coordinate and y-coordinate position information. Other modes such as control computer mode are also possible. In particular instances, a mouse and associated input devices operate in source computer mode to control a particular source computer when the mouse pointer position resides within one of the source computer windows. A mode of operation may switch based on a change in mouse position.
