INFRARED REMOTE CONTROL SIGNAL INFORMATION DETECTOR

摘要

PURPOSE: To eliminate the need of adding signals for audience rating survey to broadcasting signals and comparing audio signals at a survey origin at all times and to highly accurately survey the audience rating. CONSTITUTION: A detector 1 is provided with a light receiving part 6 for detecting infrared remote control signals emitted from an infrared ray remote controller 3 so as to operate a survey object 2. A signal cable 31 is connected to the detector 1 and an infrared ray emitting part 5 for sending out infrared signals to the light receiving part 4 of the survey object 2 based on the information of the infrared remote control signals received by the detector 1 is connected to the tip of the signal cable 31.
