Abstract
A system comprising a recording apparatus for recording record information onto a recording medium and a reproducing apparatus for reading the record information from the recording medium and outputting it to reproduce, is provided. The record information includes: image information; a first identification information which represents any one of never copy, one copy and copy free; and a second identification information which represents either the never copy or the one copy. The never copy indicates copying is prohibited. The one copy indicates copying is once permitted. The copy free indicates copying is permitted. The recording apparatus controls recording the record information, and determines whether or not the record information is to be encrypted based upon the first identification information and the second identification information. The reproducing apparatus controls outputting the record information based upon the first identification information and whether the record information has been encrypted or not.
