A server connected to a reproduction device for reproducing video data and/or audio data recorded in a recording medium, and transmits the reproduced data through a radio communication network, to a client terminal unit. The server includes: a breakage detecting part to detect a breakage of connection by the network between the server and the client terminal unit; a suspension control part to generate a suspension control signal to make the reproduction device temporarily stop reproduction of the video data and/or audio data by the reproduction device when the breakage of connection is detected by the breakage detecting part; a reconnection detecting part to detect reconnection by the network between the server and the client terminal unit; and a resumption control part to generate a resumption control signal for making the reproduction device resume reproduction when the reconnection is detected by the reconnection detecting part.
