Abstract
An object of the present invention is to provide a system in which it is possible to pre-warn the consumer who is trying to purchase contents that cannot be written on the PD that the contents cannot be written on the PD. Based on the PD writability information, the PD writability detector determines whether the contents distributed by the distribution system notified by the distribution system detector can be written on the PD. If it is determined that the contents cannot be written, the PD writability detector requests the controller to warn the consumer.
