In a media server, a registration processing block registers a client apparatus connectable to the media server and an information provision block provides information related with the registered client apparatus to an information processing apparatus. In the information processing apparatus, when an information acquisition block acquires information related with two or more client apparatuses, then a display processing block generates display data for displaying type identification information and device identification information for each client apparatus. The type identification information is a name of the client apparatus and the device identification information is a MAC address.
