摘要： A method for operating a Right For Contents (R4C) includes: obtaining, by a terminal, a hybrid RO generated by the RI server, with the R4C items and the operation Rights For Rights (R4Rs) carried in the hybrid RO; operating the R4C items in the hybrid RO according to the R4R. A method for adding an R4R includes: a terminal receives a hybrid RO that includes the existing rights of the terminal and the newly added R4R; the terminal operates the R4C in the hybrid RO according to the new R4R. The present invention also discloses a terminal and a server. The present invention enables the RI to control the rights at a finer granularity, intensifies the RI's control on the rights, and provides a mechanism of purchasing an R4R after an RO is purchased.
