Title:
音響受信装置、プログラムおよび音響受信装置における音響信号受信方法
Document Type and Number:
Japanese Patent JP7385533
Kind Code:
B2
Abstract:
To provide an acoustic signal receiving method in an acoustic receiving device, a program and an acoustic receiving device which can suppress power consumption by optimizing whether or not to perform decoding process.SOLUTION: An acoustic receiving device 30 receives an acoustic signal AS in which embedded information SC is embedded by a microphone 31. The sound receiving device 30 includes: a volume detection unit 34 that detects volume of the acoustic signal Sas picked up by the microphone 31; a determination unit 35 that determines whether or not the detection volume detected by the volume detection unit 34 exceeds a threshold value; an extraction unit 36 that performs an extraction process for extracting the embedded information SC from the acoustic signal Sas; and a decoding unit 37 that performs a decoding process that decodes the embedded information SC into identification information ID. The decoding unit 37 performs decoding process when the detection volume exceeds the threshold value, and does not perform decoding process when the detection volume is equal to or less than the threshold value.SELECTED DRAWING: Figure 3
