ABSTRACT:
An information recording and reproduction apparatus for recording and reproducing the information supplied through the transmission line is capable of protecting the copyright by limiting the reproduction of the recorded information. A main information signal supplied through the transmission line and a deadline signal attached to the main information signal and representing the reproduction deadline of the main information signal are recorded and reproduced by a recording device and a reproduction device respectively. A temporal information signal representing the date and time is acquired. The deadline signal reproduced is compared with the temporal information signal acquired. The reproduction output of the main information signal is cut off in accordance with the comparison signal produced by the comparison. In the case where the temporal information has passed the deadline, the reproduction output of the main information signal is cut off.
