Abstract: An objective of the present invention is to avoid illicit distribution of content while allowing authentication and key exchange procedures over an external network. A measurement to obtain an RTT to a receiving apparatus (130) is carried out with a relay apparatus (120) which is between a WAN (140) and a home network (150) and connects these two networks. By making it a condition for distribution of content from a transmission apparatus (110) that the RTT value be less than or equal to a threshold it is possible to implement a usage environment for using content within the home network (150) which is equivalent to a system which uses current DLNA and DTCP IP protocols.
