DEVICE AND METHOD FOR SIGNAL REPRODUCING, DEVICE AND METHOD FOR SIGNAL RECORDING AND SIGNAL RECEIVER

摘要

PROBLEM TO BE SOLVED: To conduct a trial listening of the contents of music or the like without experiencing the breaking of a code and to reproduce high quality contents by obtaining a relatively small amount of data. SOLUTION: Signals 801 of a first code string in which a portion of the code string of a prescribed format is made into dummy data are transmitted to a code string rewriting means 1802 through a code string decomposing means 1801. Signals 806 of a second code string which supplements a portion of the dummy data in the signals 801 are transmitted to the means 1802 through a control means 1805 and the dummy data in the first code string are rewritten into the second code string. During a trial listening, signals 802 from the means 1801 are selected by a switching switch 1808. When the second code string 806 is obtained through purchase of the contents, signals 803 from the means 1802 are selected.
