Abstract
An energy efficient remote control protocol uses a start bit which has a variable length which corresponds to the parity of the transmitted symbol, a guard time which is fixed at a predetermined length, and a data transmission time which corresponds to the data to be transmitted. The data to be transmitted is transmitted as a logic low, thus improving the energy efficiency of the system. During the transmission of a code, only one stop bit is used at the end of the transmission. The guard time and parity check are used to verify proper transmission.
