An apparatus and method for preparing a variable-rate coded signal, generated by compressing a digital input signal using a variable compression ratio and including a signal portion of a predetermined type, for recording on a recording medium. In the apparatus, a circuit generates a flag signal indicating the signal portion of the a predetermined type in the variable-rate coded signal. A signal-type marker generating circuit generates a signal-type marker in response to the flag signal. Finally, a circuit multiplexes the signal-type marker with the variable-rate coded signal to produce a multiplexed signal for recording on the recording medium. The signal-type marker is located adjacent to the signal portion of the predetermined type to indicate the signal portion of the predetermined type in the multiplexed signal. Where the multiplexed signal is divided into packs of plural packets, the signal marker is included in an entry pack located immediately preceding a packet that includes the signal portion of the predetermined type. Where the multiplexed signal is divided into sectors and each sector includes a sector header, the signal marker is included as subcode in the sector header of a sector that includes the signal portion of a predetermined type.
