THE PRESENT INVENTION RELATES TO A METHOD AND A DEVICE FOR THE FAST VERIFICATION OF SECTOR ADDRESSES (9) IN A DATA STREAM (2) OBTAINED FROM A RECORDING MEDIUM (1) UPON A REQUEST FROM A MICROCONTROLLER (13). ACCORDING TO THE INVENTION, THE METHOD COMPRISES THE STEPS OF: READING THE DATA STREAM FROM THE RECORDING MEDIUM; DECODING THE DATA STREAM TO OBTAIN A DECODED DATA STREAM COMPRISING USER DATA AND SECTOR ADDRESSES; COMPARING THE SECTOR ADDRESSES WITH A RANGE (12) OF VALID SECTOR ADDRESSES; AND TRANSMITTING ONLY USER DATA HAVING SECTOR ADDRESSES WITHIN THE RANGE OF VALID SECTOR ADDRESSES; WHEREBY DEDICATED COMPARING MEANS (10) ARE PROVIDED FOR PERFORMING THE COMPARING STEP INDEPENDENTLY OF THE MICROCONTROLLER.
