Claim 4:
5. A non-transitory computer-readable storage medium having stored thereon a program which when executed causes a computer to function as a display control device by:
acquiring a video to be displayed;
identifying, within the video acquired by the acquired video, a region in which there is no change or an amount of change is lower than a predetermined threshold;
applying terminal identification information to a PN sequence generator to output a PN sequence;
with the PN sequence and transmission data, generating transmission data transformed into white noise;
performing brightness modulation or RGB modulation;
generating an encoded video obtained by encoding, as an optical communication signal, the transmission data into the identified region;
generating an encoded video obtained by encoding terminal identification information into a region other than the identified region (into which the transmission data is encoded); and
causing a display to display the encoded video, and to display unique terminal identification information of one of a plurality of communication terminals in a terminal identification signal, the terminal identification information uniquely identifying each of the plurality of communication terminals, to enable a unicast service.
