Abstract
A reproducing and/or recording system in which copy generation of an information signal is controlled through the use of copy control information that is added to the information signal. The copy control information takes on at least one of three possible states, a one-copy allowed state, a more-copy prohibited state and a copy absolutely prohibited state. The system determines an initial copy control state for the signal being reproduced and determines the state of copy control information to be added to the reproduced signal based on at least the initial copy control information. During recording it may be determined that no further copy control information is to be added to the signal.
