  • Method for scrambling and/or descrambling FM subcarrier data
    Patent number: 5912973
    Abstract: An FM multiple radio broadcasting receiver includes a data group number and data packet number derivation circuit by which a data group number and a data packet number included in a prefix of FM subcarrier data are derived. A first random number generator generates a first random number on the basis of the data group number, the data packet number and scramble key data which is outputted from a scramble key generation circuit, and sets the first random number in a second random number generator as its initial value. Therefore, it is possible to appropriately scramble or descramble with using packet structure of the FM subcarrier data.
