A method and apparatus is provided for receiving and/or reproducing a digital signal, capable of efficiently recording a compressed, packeted digital signal (170-173) and inhibiting a copy thereof. An input packet signal is added (Fig. 9) with a time stamp indicating a relative time of an arrival of the packet, and the packet signals of digital information with the added time stamps are recorded at reduced intervals (Fig. 8(3)) therebetween. In reproducing, a packet interval adjusting circuit (Fig. 11) restores the original packet intervals in accordance with the time stamps, and then a time stamp change circuit (Fig. 9) changes at least one bit of the time stamp and thereafter outputs the digital information.read more
