Abstract: 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.

Abstract: Sensing devices 1a, 1b, . . . , 1n for sensing a person 2 moving close to a plurality of previously selected locations and receivers 4a, 4b, . . . , 4n for receiving identification data transmitted from an identification tag 3 co-operate to acquire behavior data indicative of the movement pattern of a person 2, and a processing device 6 compares the behavior data to reference data relating to an authorized person previously identified by the identification data, in order to determine whether or not the result of the comparison indicates the existence of a difference. Then, when the processing device determines that the result of the comparison does not indicate the existence of a difference, it does not transmit the image data acquired via cameras 5a, 5b, . . . , 5n disposed in predetermined locations to a delivery system 8.
