VIDEO GAME IN A PAC USING RFB

Image of classic video game programmed in PAC

RFB PROTOCOL

RFB or "Remote Frame Buffer" protocol was created in the Olivetti Research Laboratory to manage graphic interfaces remotely. The idea was to create a protocol as simple as possible, so as much hardware as possible (thin clients) could deal with it. One of its simplest function is to draw rectangles specifying basically 5 parameters: x position, y position, width, height and color. In that way an image can be composed of multiple rectangles, sending only 5 parameters per rectangle and there's no need to send desktop image pixel by pixel to the thin client, saving bandwidth.
