ABSTRACT:
A keyboard, video, mouse (KVM) switch implements a picture-in-picture (PIP) function to allow desktop images from multiple computers to be displayed on the user console monitor. The KVM switch switches a first one of the multiple computers to the user console in a manner. The KVM switch further establishes a desktop sharing and remote control relationship between the first computer and each of the other computers, so that the first computer acts as a client which can see the desktop of the other computers (servers) and control them. The desktop images of the other computers are displayed on the console monitor as windows, which can be moved and re-sized. Audio data from the other computer are also transmitted to the user console. The PIP function is primarily implemented in software and no special video processing hardware is required in the KVM switch.
