Title:
TRANSMISSION DEVICE AND RECEPTION DEVICE
Document Type and Number:
Japanese Patent JP2015231055
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a transmission device and a reception device that enables execution of processing at a specific timing at a reception side in a mechanism of transmitting data by using a sound transmission medium.SOLUTION: An acoustic transmission system has at least a transmission device 1 for superimposing information on an acoustic signal and emitting sounds, and a reception device 2 for collecting the sounds and extracting the information. The transmission device 1 divides a frame containing a command and Elapse time into plural blocks and transmits the blocks on a frequency-band basis. The reception device 2 demodulates these blocks to obtain the command and the Elapse Time, and executes the processing specified by the command at a specified timing by the Elapse Time. Accordingly, the processing can be executed at a specific timing at the reception side in a mechanism for transmitting data by using a sound as a medium for transmitting sounds.
