A formatter is provided and, when a code sequence which matches a part (‘00’) of the head of a predetermined code sequence detected by a start code prefix detection unit, is detected, the start code prefix detection unit detects the residual part (‘00’, ‘00’, ‘01’, ‘E0’) of the detected predetermined code sequence to detect a pattern of (‘00’, ‘00’, ‘00’), and the formatter outputs one (‘00’). After the boundary of packets is defined, amongst data which are not transferred to a decoding buffer, data corresponding to code sequences other than the code sequence (‘00’, ‘00’, ‘01’, ‘E0’) indicating that the packet boundary are output to the decoding buffer. Therefore, when separating a coded and multiplexed signal, control of an input buffer reading control circuit is simplified, and thereby the hardware scale is reduced, resulting in an inexpensive apparatus for reproducing a digital code sequence.
