The　infrared　remote　control　devices　are　used　to　operate　in　the　most　of　modern　household　applications,　such　as　television,　DVDs,　the　conditions.　With　the　development　of　the　society　and　smart　home,　there　are　more　and　more　home　appliances　and　more　infrared　remote　control　devices　used　to　match　them.　But　the　infrared　remote　control　device　can＇t　be　used　to　manipulate　the　different　kinds　of　home　appliances;　therefore　it　isn＇t　compatible　with　the　others　and　leads　to　the　waste　of　resources.　So　this　paper　proposed　an　application　with　the　single-chip　microcomputer　and　USB　interface,　gives　out　the　design　of　infrared　remote　control　system,　which　can　code　and　decode　all　of　the　infrared　remote　control　protocol,　and　integrate　with　the　transmission　and　receiver.　Then　it＇s　able　to　replace　the　infrared　remote　control　before　to　save　the　resources.　©　2010　IEEE.
