Abstract:
A data receiver terminal for receiving scrambled data supplied from an information supplier comprising:a multiplexing circuit for multiplexing said scrambled data and an identification code identifying said data receiver terminal or a user;a data recording/reproducing apparatus for being able to record and reproduce a multiplexed data output from said multiplexing circuit;an extracting circuit for extracting said identification code from said multiplexed data reproduced from said data recording/reproducing apparatus;a comparator for comparing said identification code extracted by said extracting circuit with said identification code provided by said multiplexed circuit;a descrambling circuit for descrambling said scrambled data of said multiplexed data reproduced from said data recording/reproducing apparatus; and,wherein said descrambling circuit descrambles said scrambled data of said multiplexed data only when the descrambling of said scrambled data is permitted according to a result of a comparison performed by said comparator.
