DISTRIBUTION DEVICE, DISTRIBUTION SYSTEM, DISTRIBUTION METHOD, ELECTRONIC MACHINE, PLAY DEVICE AND RECEIVING PROGRAM

A distribution system comprises a play device 1, a distribution device 2 and an electronic machine 3 to function as a content distribution system. The distribution device 2 receives content signals and authorization information ECM (entitlement control message) from a play wave. Afterward, the distribution device 2 distributes the content signals and authorization information ECM to the electronic machine 3 by a communication means and in the same format as play wave transmission. A content protection disabling portion 30 of the electronic machine 3 is capable of performing content protection processing on content signals and simplifying the structure of the electronic machine 3, regardless of whether the content signals are transmitted from the play device 1 by a play wave or distributed from the distribution device 2 by a communication means.
