KR940017371A - Data transmission and reception method and device using infrared ray - Google Patents

Abstract

The present invention relates to a method and apparatus that is capable of transmitting and receiving infrared data without being affected by data interference caused by other infrared signals. Is characterized in that the data is assigned an address, and only data to which its own address is added is input.
