INFRARED COMMUNICATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an infrared communication device in which communication efficiency can be improved, in the communication of infrared multi-value modulation.

SOLUTION: The infrared communication device 1 of Fig.1 includes a multi-value modulating section 13 which performs ASK modulation by a multi-value number with data designation; a data frame analyzing section 14 which analyzes a data frame inputted from the multi-value modulating section 13; a minimum turnaround-time measurement frame creating section 15 which creates a measurement frame for obtaining a minimum turnaround time; a minimum turnaround-time measurement frame analyzing section 16 which analyzes the measurement frame created by the minimum turnaround time measurement frame creating section 15; a minimum turnaround time storing section 17 which stores a minimum turnaround-time value for each multi-value number inputted from the minimum turnaround-time measurement frame analyzing section 16; and a data frame creating section 19 which creates a data frame to be transmitted by infrared rays.
