ABSTRACT:
A satellite receiver which can selectively inhibit the reception of radio wave of the improper program. This receiver comprises: a receiver unit; a reproducer unit to reproduce the signal received by the receiver unit; a control unit including (a) a first memory to store the designated transponder number, (b) a second memory to store the transponder number which is parental locked, and (c) a generator to generate a parental lock signal when the memory contents of the first and second memories coincide; and means for disabling the signal from the designated transponder to be reproduced by the reproducer unit in response to the parental lock signal. With this receiver, the radio wave from the designated transponder cannot be received.
