Abstract: The server apparatus is applied to a game system which has a storage unit storing gaming dynamic images different from each other in association with a stream ID for identifying each gaming dynamic image. The game system acquires a playing dynamic image photographed by a portable phone and a stream ID of the playing dynamic image via a network. Base on the acquisition result, the game system determines the gaming dynamic image whose stream ID corresponds to the stream ID of the playing dynamic image acquired as a target gaming dynamic image, and provides a dynamic-image delivery service so that a delivery screen is displayed at each personal computer, the delivery screen including a composite dynamic image where the playing dynamic image and the target gaming dynamic image are synthesized.

Abstract: A management device includes: a controller configured to control an invitation processing for introducing a first application from a first terminal of a first user to a second terminal of a second user. The first application and a second application have been executed in the first terminal. The first and second users are inter-related with respect to the second application. The controller further includes: an invitation request receiver configured to receive, from the first terminal of the first user, an invitation request information for inviting the second user to the first application; and an invitation notifier configured to transmit, to the second terminal of the second user, an invitation notification information that is based on the invitation request information for inviting the second user that has been received by the invitation request receiver.
