ABSTRACT:
A scrambling key is generated from demodulated and error-corrected FM demodulation data for use in descrambling. During this process, if error correction has not been normally conducted to an object data packet, a subsequent descrambling operation is not executed to that data packet. In addition, a descrambling operation is not carried out if the object data packet is a parity packet.
