Data or a message is displayed in a specific area of a display of a computer or an interactive terminal by using a local access network (LAN) card having processing resources and connected to a network, and a video card having a frame buffer. The LAN card takes control of the video card frame buffer independently of an operating system running into the computer or interactive terminal. Preferably, the LAN card and video card are connected to the computer by a PCI bus and the frame buffer of the video card is controlled by a PCI bus master mode.
