  • Patent number: 8533756
    Abstract: The present invention includes: a step of creating at least a play list including reproduction start times of the display terminal devices (1) and acquisition destination data indicating acquisition destinations of the creative data; and a step of transmitting the play list and the creative data to the display terminal devices (1) via the normal relay server devices (30) and the super relay server devices (20). The play list creating step creates the play list by determining the acquisition destination data in such a manner that the creative data is distributed preferentially to the super relay server devices (20) rather than to the normal relay server devices (30) and that the normal relay server devices (30) acquire the creative data from the super relay server devices (20). Because of this, the load on distribution devices for distributing creative data is reduced.
