ABSTRACT:
A relay device and a communication device capable of realizing the contents protection procedure between devices that are not connected to the same network are disclosed. A relay device and a communication device are so configured that between a device/service/sub-unit on the second network and a device on the first network which are a pair that is carrying out transmission or reception of contents to be protected, a device on the first network or a device/service/sub-unit on the second network can carry out the contents protection procedure while recognizing the target of the contents protection procedure as the relay device, so that there is no need for a device on the first network or a device/service/sub-unit on the second network to account for the other network that is connected via the relay device.
