Abstract:
A system comprising a recording apparatus for recording record information onto a recording medium as digital data and a reproducing apparatus for reading the record information from the recording medium and outputting the read record information in order to reproduce the record information recorded on the recording medium,the record information including: image information which represents an image or a picture; a first identification information which represents any one of never copy, one copy and copy free; and a second identification information which represents any one of at least the never copy and the one copy, the never copy indicating that copying of the information is prohibited, the one copy indicating that the copying of the information is permitted only once, the copy free indicating that the copying of the information is permitted, the recording apparatus comprising: an input device for inputting the record information; a first recording determination device for determining whether the first identification information included in the input record information indicates the never copy, the one copy or the copy free; a second recording determination device for determining whether the second identification information included in the input record information indicates the never copy or the one copy; a recording control device for determining on the basis of determinations of the first recording determination device and the second recording determination device whether recording the input record information onto the recording medium is permitted or prohibited; a recording device for recording the input record information onto the recording medium in accordance with a determination of the recording control device; an encryption control device for determining on the basis of determinations of the first recording determination device and the second recording determination device whether or not the input record information is to be encrypted; and an encryption device for encrypting the input record information in accordance with a determination of the encryption control device, the reproducing apparatus comprising: a read device for reading the record information from the recording medium; a first reproduction determination device for determining whether the first identification information included in the read record information indicates the never copy, the one copy or the copy free; a second reproduction determination device for determining whether or not the read record information is encrypted by the recording apparatus; an output control device for determining on the basis of determinations of the first reproduction determination device and the second reproduction determination device whether outputting the read record information is permitted or prohibited; an output device for outputting the read record information in accordance with a determination of the output control device; a decryption control device for determining on the basis of a determination of the second reproduction determination device whether or not the read record information is to be decrypted; a decryption device for decrypting the read record information in accordance with a determination of the decryption control device; a changing control device for determining on the basis of determinations of the first reproduction determination device and the second reproduction determination device whether or not the second identification information is to be changed such that the second identification information indicates the never copy; and a changing device for changing the second identification information such that the second identification information indicates the never copy, in accordance with a determination of the changing control device.
