"Apparatus for encoding bits of information for transmission.And to receive a signal and decoding from the same bits of information encoded and scrambled to produce a first and a second group of bits of information, and.Processes for the encoding of a first and a second group with symbols of information, and for decoding an encoded information signal.A process and apparatus for protecting a first group of bits of data using a second group of data bits within the transmission of digital data is described.The first and second groups of data bits are encoded for transmission in a communication network.The second group of bits of the encoded data is scrambled using a mask of shuffling generated from the first group of bits of data.The first group of bits of the encoded data and the second group of data bits encoded and scrambled are then interleaved and transmitted to a receiver.The first group of data bits are decoded and used to regenerate the mask of scramble to separate the second group of data bits encoded and scrambled.The second group of data bits may then be decoded.The results of decoding of the second group of bits of data are used to determine whether or not the first group of data bits have been decoded properly.
