Abstract
A method for distributing advertisement data to display terminal devices from a distribution server via a relay server. The relay server receives status notifications of the display terminal devices and transmits a tenor of receipt of the status notifications to the display terminal devices. The distribution server receiving status notifications and transmits the tenor of receipt of the status notifications to the relay server. The distribution server determines whether the reproduction schedule of the advertisement data has been changed and transmits a notification on a change. If the distribution server receives a request for acquisition of the as-changed reproduction schedule, the distribution server sends the as-changed reproduction schedule to the relay server. If the relay server determines that the reproduction schedule acquired from the distribution server has been changed, the relay server transmits the notification on the change of the reproduction schedule.
