Abstract:
An information output device comprising:first duplication control information superimposing means for applying a first processing by spectrum spreading a duplication control information signal generated on a basis of an added information obtained from a recording medium which indicates a number of allowable duplications of a main information signal which is recorded on said recording medium to thereby generate a first processed duplication control information signal, and for superimposing said first processed duplication control information signal on said main information signal read out from said recording medium and producing a first signal;second duplication control information superimposing means for applying a second processing different from said first processing by said first duplication control information superimposing means to said duplication control information signal to thereby generate a second processed duplication control information signal which indicates a number of allowable duplications of the main information signal, and for superimposing said second processed duplication control information signal on said main information signal and producing a second signal; andoutput means for combining said first signal and said second signal, thereby outputting said main information signal containing said first and second processed duplication control information signals.
