Abstract

A system for controlling a host computer by a portable computer comprises a switching device having a first port set, a second port set and a third port set, a host computer coupled to the first port set and the second port set of the switching device and a portable computer with a built-in keyboard, display screen and cursor control device coupled to the third port set of the switching device. The switching device includes a video codec unit coupled to the first port set for receiving analog video signals from the host computer and converting the analog video signals to digital video signals. The switching device further includes a signal controlling unit coupled to the video codec unit for receiving the digital video signals, the second port set and the third port set. The signal controlling unit transmits the digital video signals to the portable computer through the third port set for displaying the digital video signals on the display screen of the portable computer. The signal controlling unit receives controlling signals from the keyboard and cursor control device of the portable computer through the third port set and transmits the controlling signals to the host computer through the second port set.

Description

technical field

[0001] The invention relates to a system for controlling another computer host by using one computer host, in particular to a system for controlling at least one or more computer hosts by using a notebook computer. Background technique

[0002] In electronic products, there is a device that connects a host computer to multiple host computers, such as a KVM (keyboard / video / mouse) switch, which can be connected to multiple host computers and utilize a set of keyboards, display Device and mouse to control all computer hosts connected to the KVM (keyboard / video / mouse) switch. Therefore, the user does not need to purchase a set of corresponding keyboards, display devices and mice for each host computer, but only needs a set of keyboards, display devices and mice. When a user performs an access operation on a host computer connected to a KVM (keyboard / video / mouse) switch, the image signal of the host computer will be processed and then displayed on the display dev...
