PURPOSE: A main control set of a wireless digital board is provided to form a highly integrated circuit, to process data efficiently, and to reduce a manufacturing and a maintenance expense of a hardware by integrating a part controlling a modem and a part controlling an LED(Light Emitting Diode) board into a single PCB(Printed Circuit Board). CONSTITUTION: The modem(102) receives the wireless data. A ROM(104) processes the data received through the modem via a TCP/IP(Transmission Control Protocol/Internet Protocol) stag by an OS(Operating System). A RAM(108) executes a repeated display job in a constant time through an embedded program after storing the processed data. A graphic controller(110) controls a module(114) based on the stored data.
