METHOD FOR INDICATING LETTER CALL CONTENTS IN REAL-TIME AND REAL TIME LETTER CALL CONTENTS INDICATION SYSTEM

摘要

PURPOSE: A method and a system are provided to indicate a letter call contents in real-time on an indoor/outdoor information display device by receiving letter information transmitted as a wireless signal. CONSTITUTION: A system for indicating a letter call contents in real-time consists of a message providing device(100), a wireless signal receiving device(200), a computer(300), and a message signal processor unit(500). The message providing device converts a message to be displayed into a wireless signal by using a wireless communication base station(120), and then transmits the wireless signal to a wireless signal receiver(210) of the wireless signal receiving device. The wireless signal receiving device extracts the message from the received wireless signal in a letter extractor(220), and transmits it via a computer interface part(230). The computer receives the extracted message, and converts it into a display format. A signal converter(510) of the message processor unit converts the converted message into a new converted message, and an amplification distributor(520) amplifies the new converted message, and distributes it into information display device(400).
