Abstract: A display device, system, and method are provided. The display device has a communication interface adapted to communicate with an archival storage device, a content source adapted to acquire content in an acquisition form, a presentation system for presenting content in a form that is different from the acquisition form and a memory for storing content. A controller is provided and is adapted to receive acquired content from the content source, to form presentation content that corresponds to the acquired content said presentation content adapted for presentation using the presentation system and to cause the acquired image content and the corresponding presentation content to be stored in the memory. The controller is further adapted to cause the communication interface to transfer acquired content to the archival storage device and to delete the transferred acquired content from the memory.
