| 7. An information-processing device comprising:
a first interface configured to transmit content to at least one of a plurality of communication units belonging to a first
group through a network;
a second interface configured to receive unique identifications assigned to a plurality of communication units belonging to
a second group;
a first storage area configured to store a first unique identification received through the second interface, the first unique
identification being assigned to a first communication unit belonging to the second group;
a first judgment unit configured to determine whether a unique identification received through the first interface is stored
with a same value as the first unique identification in the first storage area, the unique identification being registered
to the first communication unit belonging to the first group;
a content supply unit configured to transmit the content to the first communication unit belonging to the first group via
the first interface when the first judgment unit determines that the unique identification is stored with the same value as
the first unique identification in the first storage area;
a second storage area configured to store a pair of the unique identification registered to the first communication unit belonging
to the first group and a first content identification identifying the content transmitted to the first communication unit
belonging to the first group;
a third storage area configured to store a value of a second unique identification received through the second interface while
the content supply unit transmits the content to the first communication unit belonging to the first group through the first
interface, the second unique identification being assigned to a second communication unit belonging to the second group;
a second judgment unit configured to determine whether a value of unique identification received through the first interface
is stored in at least one of the first storage area and the third storage area, the unique identification being registered
to a third communication unit belonging to the first group; and
a content output management unit configured to search for the unique identification registered to the third communication
unit belonging to the first group by using a second content identification as a search key required by the third communication
unit belonging to the first group in the second storage area when the second judgment unit determines that the value of the
unique identification is stored in at least one of the first storage area and the third storage area, wherein
the content output management unit determines whether to transmit the content to the third communication unit belonging to
the first group when the value of the unique identification is stored in the second storage areas as a result of the search.
