ABSTRACT:
A mapping processor is configured to receive a current PAT from the input data stream, and to compare input program numbers in the current PAT to known program numbers in the stored format table. If the input program numbers in the current PAT are the same as the input program numbers in the stored format table, then another data stream is output having output program numbers from the stored format table. If the input program numbers in the current PAT are not the same as the input program numbers in the stored format table, then another data stream is output having reassigned output program numbers. The reassigned output program numbers may be from another stored format table in the memory, if the other stored format table has input program numbers that match the input program numbers in the current PAT. If not the reassigned output program numbers may be newly generated.
