In a content distribution system in which a content distribution device distributes video content to a content playback terminal, the content distribution device multicasts video content added with cash control information to the content playback terminal and other content playback devices, before a user plays back video content selected from a distribution menu. The distribution playback terminal writes the video content in a temporal storage unit included in the distribution playback terminal. If the video content selected by the user is stored in the temporal storage unit, the video content is played back. On the other hand, if the video content selected is not stored in the temporal storage unit, a distribution request for the video content selected is made to the content distribution device.
