Abstract
A method and apparatus is provided for receiving and/or reproducing a digital signal, capable of efficiently recording a compressed, packeted digital signal and inhibiting a copy thereof. An input packet signal is added 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 therebetween. In reproducing, a packet interval adjusting circuit restores the original packet intervals in accordance with the time stamps, and then a time stamp change circuit changes at least one bit of the time stamp and thereafter outputs the digital information.
