Abstract:
1. A reproduction apparatus for reproducing video data and/or audio data from a medium dedicated to reproduction or a recordable medium having video data and/or audio data recorded thereon, the video data and/or audio data being generated by superimposing information concerning copying consent on a digitized video signal or audio signal which has undergone addition of an error-correction code for error-correction and then been modulated in accordance with a modulation rule adapted for the recording medium, the reproduction apparatus comprising: a demodulator which demodulates data modulated in accordance with the modulation rule; a temporal store which stores the data demodulated by the demodulator; an error-corrector which error-corrects the demodulated data stored in the temporal store based on the error-correction code, the error-corrected data being stored in the temporal store; a reproducer which reproduces the superimposed information concerning copying consent from the error-corrected data processed by the error-corrector and stored in the temporal store; an output controller which performs output control of the error-corrected data which is stored in the temporal store based on the reproduced information concerning copying consent; and a medium detector which detects whether a medium is a medium dedicated to reproduction; wherein the output controller stops outputting the error-corrected data in response to occurrence of both (1) that the error-corrected data was reproduced from the medium dedicated to reproduction based upon detection by the medium detector, and (2) that the reproduced information concerning copying consent stored in the temporal store indicates that copying once was permitted at one time and no more.
