Abstract
In a contents transmission/reception system, the transmission of the contents to the corresponding reception device is permitted only in the case where the device identification information searched out by the device identification information search unit and the device identification information registered by the device identification information registration unit coincide, so that it is possible to provide the contents only to the limited reception devices, and it is possible to prevent the illegal reception of the contents.
