ABSTRACT:
In a broadcast system for transmitting a communication signal to a plurality of receiver units, each receiver unit having associated therewith respective authorization information identifying subsets of the communication signal the receiver unit is authorized to process, a method for controlling access to the communication signal includes the step of receiving a conditional instruction. The conditional instruction specifies a modification of the authorization information conditioned upon whether the receiver unit belongs to a receiver unit category. The method further includes the step of executing the conditional instruction to modify the authorization information conditioned upon whether the receiver unit belongs to the receiver unit category.
