PROBLEM TO BE SOLVED: To perform infrared communication between an optional infrared transmitter and an optional infrared receiver regardlessly of the difference of communication protocols by transmitting a communication mode information for designing a communication protocol for transmitting data before transmitting the data from the infrared transmitter, and then transmitting the data with the designated communication protocol. SOLUTION: When a transmission start signal START is given, the communication mode information for designating the communication protocol for transmitting the data from a communication mode generator 16 is transmitted through an infrared module 20 before transmitting the data, then the infrared transmitter 12 outputs a transmission enable signal 'en' to transmit the data with the? communication protocol designated from an IrDA modulator 18 (IrDA in this case) through the module 20. The signal received by an infrared module 22 is discriminated that the communication protocol of data is the IrDA by a communication mode discriminator 24 and converted into a parallel data by an IrDA demodulator 30. |
