Recently, there has been an increasing demand for multi-PC systems in which a large number of users use a PC in shared facilities such as military barracks, libraries, educational facilities, call centers, financial institutions, and business centers. Conventional methods of implementing such a multi-PC system include the following methods.

First, the most common method is to connect a plurality of monitors to one main body. There are a graphic card method and a USB connection method as a method for enabling this.

First, the graphics card method allocates a session for each user using the Multi Session of Windows XP. The user interface is directly connected to the user's monitor from the graphics card installed in the main body PC, and the USB port is further connected to the hub Hub or station to connect the keyboard and mouse. The internal memory of the graphics card is advantageous in terms of multiparty memory usage, but the distance between the main PC and the user monitor is limited to about 5M to 10M, and the PCI- There is a restriction that the board must be used. In addition, the operating system is limited to the Windows series, and there is a limit to the scalability because there are four or fewer users supported per unit.

Next, the USB connection method allocates a Session to each user by using the Multi Session of Windows XP as in the above-described graphic card method, and assigns a user interface to a hub or station which is an extension of the USB port of the main PC To connect the monitor, keyboard and mouse. Compared to the graphics card method, the configuration is simple, but the video playback performance is lower than that of the graphics card method.
