CONTENT PROVISION SYSTEM USING SPATIAL LIGHT TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To provide a content provision system which can simply provide contents needed for users through portable terminals on the basis of spatial light based ID information transmission in multiple places such as various facilities.SOLUTION: A spatial light transmitter 1 projects spatial light having ID information superposed thereon from a fixed position. A user brings a portable terminal 40 having a spatial light receiver 30 connected thereto with him and, when the user has moved to the vicinity of the spatial light transmitter 1, the spatial light receiver 30 receives spatial light with a light-receiving unit 31. The spatial light receiver 30 acquires ID information from the received signal of the light-receiving unit 31 by demodulating it and outputs the ID information to the portable terminal 40. The portable terminal 40 reproduces a content selected on the basis of the ID information.
