Abstract
A remote access device is disclosed for capturing, digitizing and communicating video signals from a host computer to a remote computer. The remote computer returns keyboard and mouse signals through the remote access device to the host computer to control the host computer as though the remote keyboard and mouse were directly connected to the host computer. The remote access device includes a circuit module interface for the host computer that allows the remote access device to operate independently of any operating system characteristics associated with the host computer.
Claims11
A circuit module for a remote access computer, having in operation therein a remote access engine, to communicate between a data bus and the remote access engine, comprising:
- a video capture circuit to capture analog video signals created by an external host computer different from the remote access computer, to digitize and packet the captured video signals;
- and to sync the captured video signals to a video output on an external remote site computer different from the external host computer;
- a mouse circuit to capture user input mouse signals created by the external remote site computer and captured by the remote access engine from the external remote site computer when initiated by the external remote site computer via a network connection;
- and
- at least one of said video capture circuit or mouse circuit including a mouse lag correction routine to coordinate the mouse signals captured by the mouse circuit and the video capture circuit.
A remote access computer installed between at least one host computer and a remote computer, the host computer having a particular type of operating system, the remote access computer comprising:
- a video capture circuit connected to a standard video output connector of the host computer to receive an analog RGB video signal normally destined for a standard monitor associated with the host computer;
- a keyboard/mouse interface connected to at least one of:
- a standard keyboard input connector of the host computer to deliver a keyboard control signal normally delivered by a standard keyboard associated with the host computer;
- and
- a standard mouse input connector of the host computer to deliver a mouse control signal normally delivered by a standard mouse associated with the host computer;
- a video process circuit, in communication with the video capture circuit, to synchronize and digitize the analog RGB video signal received by the video capture circuit;
- a network interface communicating with a network medium which is also communicating with the remote computer;
- a video interface communicating with:
- the video process circuit to receive the synchronized and digitized RGB video signal, and
- the network medium to deliver the digitized RGB video signal to the remote computer to allow the remote computer user to view in essentially real-time the same RGB video signal as provided by the host computer including the mouse control signal adjusted for lag;
- and wherein:
- the video capture circuit, keyboard/mouse interface, video process circuit, network interface, and video interface all operate independently of the particular type of operating system on the host computer.
