Claim 0:
1. A display control device comprising:
at least one processor;
a video acquiring section of the at least one processor, when executed by the at least one processor, configured to acquire a video to be displayed;
a region identification section of the at least one processor, when executed by the at least one processor, configured to identify, within the video acquired by the video acquiring section, a region in which there is no change or an amount of change is lower than a predetermined threshold;
a video generating section of the at least one processor, when executed by the at least one processor, configured to:
(i) apply terminal identification information to a PN sequence generator to output a PN sequence,
(ii) with the PN sequence and transmission data, generate transmission data transformed into white noise,
(iii) perform brightness modulation or RGB modulation,
(iv) generate an encoded video obtained by encoding, as an optical communication signal, the transmission data into an identified region, and
(v) further generate the encoded video obtained by encoding terminal identification information into a region other than the identified region into which the transmission data is encoded; and

a display control section of the at least one processor, when executed by the at least one processor, configured to cause 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.
