Abstract

An information transmitting/receiving system is disclosed which includes a base station apparatus and a monitor apparatus, the system being arranged to let the base station apparatus offer more content information to the monitor apparatus than before. On receiving a content transmission request, the base station apparatus performs an authenticating process using monitor apparatus registration information in order to send content information only to the registered monitor apparatus authorized to receive the content information. The monitor apparatus may register with a plurality of units of the base station apparatus. When the monitor apparatus selects any one of the multiple units of the base station apparatus to request transmission of content information therefrom, the selected base station unit transmits the requested content information to the requesting monitor apparatus.
