To provide a receiving apparatus for receiving digital broadcasting signals from a plurality of broadcasting companies in different receiving modes from each other at low cost. <??>It is identified to what limited receiving mode the IC card, mounted to the IC card interface section, corresponds. When the IC card is an effective IC card which corresponds to the limited receiving mode of the stream TS output from the switch by the user through selecting operation, the CPU performs control in such a manner that the limited receiving processing is conducted for the stream TS, by use of the contract information and the scramble key information controlled by the IC card. Specifically, when the program designated by the user through selecting operation is of the limited receiving, the CPU allows the descrambling section to release the scramble, so that the user can watch and listen to the program. By simply exchanging the IC cards mounted on the interface section, it becomes possible to receive the digital broadcasting signals from the broadcasting companies. <IMAGE> |
