    • In a data carrier (1) which includes receiving means (5) for receiving a modulated carrier signal (MTS) which contains a data signal (DS1) encoded in conformity with an encoding method (MA, PW, MI, RTZ, FSK, PSK), demodulation means (9) for demodulating the received modulated carrier signal (MTS) and for outputting the encoded data signal (DS1) contained therein, decoding means (10, 20) for decoding the encoded data signal (DS1) and for outputting data (D1, D2), and data processing means (11) for processing the data (D1, D2) output by the decoding means (10, 20), the decoding means (10, 20) are provided with at least a first decoding stage (12) and a second decoding stage (13), the first decoding stage (12) being arranged to decode a data signal (DS1) encoded in conformity with a first method (RTZ) whereas the second decoding stage (13) is arranged to decode a data signal (DS1) encoded in conformity with a second method (MI).
    • 在包括接收装置(5)的数据载体(1)中,所述接收装置(5)用于接收包含根据编码方法(MA,PW,MI,RTZ,FSK,PSK)编码的数据信号(DS1)的调制载波信号 ),用于解调所接收的调制载波信号(MTS)并用于输出其中包含的编码数据信号(DS1)的解调装置(9),用于对编码数据信号(DS1)进行解码并输出数据的解码装置(10,20) (D1,D2)和用于处理由解码装置(10,20)输出的数据(D1,D2)的数据处理装置(11),解码装置(10,20)至少设置有第一解码级 (12)和第二解码级(13),所述第一解码级(12)被布置为对根据第一方法(RTZ)编码的数据信号(DS1)进行解码,而所述第二解码级(13)被布置为 解码按照第二种方法(MI)编码的数据信号(DS1)。
