Title: Power saving infrared keyboard transmission method

Abstract: A power saving infrared keyboard transmission method adapted for data transmission of a cordless computer keyboard is disclosed. The cordless keyboard has a transmission modulus comprising a microprocessor which converts the information related to the operation status of the keys of the keyboard into a series of pulses comprised of at least a first data byte and a second data byte. A leader code and a start code are added to the series of pulses in front of the first data byte and the leader code and the start code are transmitted before the data bytes are transmitted. A receiving modulus which is coupled to a host machine receives the data bytes together with the leader code and the start code. The leader code and the start code are received first to serve as an identification of the transmission of the data bytes so that the receiving modulus receives and interrupts the received data efficiently and effectively.
