HIGH SPEED SCREEN SHARING NETWORK SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a high speed screen sharing network system in which a monitor screen shared between a master device and plural slave devices connected in a network can be reloaded at a high speed. SOLUTION: The computers of a master device teacher system and plural slave device student system connected in a network 10 are operated by a common operating system OS. A property manager PM (PMT, PMS) and a dual video card 110(110T, 110S) are installed in this OS. The PM operates the management of the network and the screen display of monitors M1-M3 independently of the OS and an application on the OS. The video card 110 is in charge of the hardware processing of the screen display shared between the master device and the slave devices under the management of the PM. The slave device screens can be operated in a real time by the mouse and keyboard operation of the master device through the PM independent of the OS.
