Abstract: When the portable reproduction device 4 and the reproduction device 6 establish the communication by the near-distance communication part 56 and 72, a right state transmission means 48 of the portable reproduction 4 transmits to the reproduction device 6 the right state data based on the right data recorded at the right record part 50. Reproduction instruction acquisition means 66 of the reproduction device 6 receives the instruction to reproduce the contents for the reproduction device from the user. According to the right state data transmitted from the portable reproduction means 68 determines whether the reproduction device 6 has the right for the contents instructed to reproduced or not. When it is determined that the right exists, reproduction means 70 reproduce the contents for the reproduction device recording at the content record part 64. When it is determined that no right exists, reproduction is not permitted.
