DATA TRANSMISSION/RECEPTION CONTROL DEVICE AND DATA TRANSMISSION/RECEPTION SYSTEM, METHOD, AND PROGRAM

摘要

A portable terminal (2) is used as a data transmission/reception control device for delivering AV data inside home to an authentic AV device outside home.  The portable terminal (2) comprises: a proximity confirming unit (23) for confirming whether a first proximity condition between a data transmission device and the portable terminal is satisfied or not; a proximity device registration authentication processing unit (21) which, when performing authentication between the data transmission device and the portable terminal, then succeeding in the authentication, and confirming that the first proximity condition is satisfied, registers the identification information of the portable terminal into the data transmission device; another proximity confirming unit (27) for confirming whether a second proximity condition between a data reception device and the portable terminal is satisfied or not; a registration start authentication processing unit (26) which, when performing authentication between the data reception device and the portable terminal, then succeeding in the authentication, and confirming that the second proximity condition is satisfied, acquires the identification information of the data reception device; and a registration authentication processing unit (22) which, when performing authentication between the data transmission device and the portable terminal and then succeeding in the authentication, registers the identification information of the data reception device into the data transmission device.
