遥控技术在电视接收机上的运用经历了漫长的岁月。它从有线发展到无线,从无线电波、超声波变为红外波,从模拟调制发展为数码调制。特别是数字技术及中央微处理器的迅猛发展,对多功能红外数码技术的实现起了决定性的作用。一块价廉而质优的CPU(中央微处理器),其功能可与75～100块中小规模的逻辑电路相等效。
Remote control technology in the television receiver has experienced a long time. It develops from wired to wireless, from radio waves, ultrasonic waves into infrared waves, from analog modulation to digital modulation. In particular, the rapid development of digital technologies and central microprocessors has played a decisive role in the realization of multi-functional infrared digital technologies. A cheap and good quality CPU (Central Microprocessor), the function can be equivalent to 75 to 100 small and medium-sized logic circuits.
