Abstract: A method and system is disclosed for synchronizing the virtual and physical mouse cursors of a local computer and a remotely controlled computer. Video signals generated by a host computer are transmitted to a client computer in order to allow the user of a client computer to have a virtual presence on the host computer. However, the signals transmitted by the host computer may contain errors that can cause a physical mouse to lose synchronization with a virtual mouse. Therefore this virtual presence architecture uses USB protocol and human interface descriptors that support the movement of a mouse to an absolute position in order to synchronize a virtual mouse cursor with a physical mouse cursor.

Abstract: A system for processing Internet requests that permits multiple binds to the same socket number at the same time on the same computer. A separate domain processing shell may be provided for each domain being hosted on a particular platform, and each domain may be mapped to a unique IP address. When a request for a service is received with a first IP address, that request may be routed to the associated shell, where it is bound to the designated socket number. When a request with a second IP address is received for the same service, it may be routed to another shell and be bound to the same socket number.

Abstract: A method and system is disclosed for incorporating a virtual presence server on a host computer. Video signals generated by a host computer are transmitted to a client using the virtual presence server in order to allow the user of a client computer to have a virtual presence on the host computer. However, the virtual presence server should not interfere with the main functions and operations of the host computer. Therefore this virtual presence server uses a stand alone device, such as a PCI card, as the virtual presence server in order to retain independent functionality from the host computer and occupy minimal physical space and power.

Abstract: A method and system is disclosed for perfecting the images generated by a KVM switch. Video signals generated by a host computer are transmitted to a client computer in order to allow the user of a client computer to have a virtual presence on the host computer. However, the signals transmitted by the host computer may contain errors that would impair the client user's ability to remotely control the host computer. Therefore this virtual presence architecture uses phase locked loops to compare screen data that is being sent to the client and removes errors so that the user data is properly transmitted and displayed.

Abstract: A system, method, and apparatus according to an embodiment of the invention uses a processor to transfer information from a first device to a common area. The information is then transferred from the common area to a second device, thereby bypassing restrictions that may impede a transfer of the information directly from the first device to the second device. In an exemplary implementation, a PCI card initiates the transfer of information from a video frame buffer of an AGP video card to a memory buffer on the PCI card, using an interrupt handler loaded during configuration of the PCI bus.
