Scramble transmission apparatus and signal processing apparatus

Image Number 6 for United States Patent #5515437.

The occurrence of malfunction on the reproduction side is avoided by preventing a scrambled signal from being coincided with a reserved word in the signal when a scramble process is carried out in order to release a transmission signal to specific users. The scramble process includes at least one of methods of (1) bit-inverting specified codes of the transmission signal code by code, (2) limiting bits to be scrambled from a specified position in the transmission signal, and (3) limiting codes to be scrambled to specific codes.
