ABSTRACT:
An information-processing device includes a first interface configured to transmit content through a network to a first communication unit having a first unique identification, a second interface configured to receive a second unique identification allocated to a second communication unit, a first storage area configured to store the second unique identification through the second interface, a first judgment unit configured to determine whether the first unique identification received through the first interface is stored in the first storage area, a content supply unit configured to transmit the content to the first communication unit via the first interface when the first judgment unit determines that the first unique identification is stored in the first storage area, a second storage area configured to store a third unique identification allocated to a third communication unit during the content supply unit transmits the content and a management unit configured to delete all unique identifications from the first storage area and shift the third unique identification from the second storage area to the first storage area when the content supply unit has transmitted the content to the first communication unit completely.
