Baud rate modulation encoding/decoding method and device for remote controller

Abstract

The present invention generally relates to encoding/decoding method and device used for remote controller, which utilizes baud rate to encrypt data for transmission. The encoding device of the present invention comprises an encoder for encoding an identification code into an encrypted code; an interpreter for interpreting the un-encoded portion of the identification code and the encrypted code into a transmission signal. Wherein, when the encrypted code is in a first base, the plain code corresponding to the encrypted code will be transmitted with a first baud rate; and when the encrypted code is in a second base, the plain code corresponding to the encrypted code will be transmitted with a second baud rate. The decoding device according to the present invention comprises a receiver for receiving the transmission signal; a interpreter connected to the receiver for interpreting the transmission signal into a received signal; a encoder for utilizing the same encoding algorithm as in the transmitter to generate a comparison code; and a processor for comparing the received signal and the comparison code and for the process control.
