• third medium mounting means for detachably mounting a third recording medium;
• first selection means for selecting arbitrary contents from the encrypted contents stored in said first recording medium in accordance with an instruction from an operator, and for decrypting the selected encrypted contents to generate first contents;
• second selection means for selecting arbitrary second contents from the non-encrypted contents stored in said second recording medium in accordance with an instruction from the operator;
• combining means for combining said first contents and said second contents in accordance with an instruction from the operator, and creating combining mode data which represents a combing mode;
• recording means for storing instruction data which identifies said first contents, said second contents and said combining mode data in said third recording medium, in response to an instruction from the operator;
• and
• output means for acquiring the instruction data stored in said recording medium, said second contents and said combining mode data, acquiring said first contents designated by said instruction data, combining said first contents and said second contents on the basis of said combining mode data as acquired, and outputting an image obtained by the combining.

A contents processing system comprising:

• medium mounting means for mounting a first recording medium in which contents protected by a predetermined right have been stored, mounting a second recording medium in which contents have been stored, and mounting a third recording medium;
• first selection means for selecting arbitrary first contents from the contents stored in said first recording medium;
• second selection means for selecting arbitrary second contents from the contents stored in said second recording medium;
• combining means for combining the first contents selected by said first selection means and the second contents selected by said second selection means;
• display means for displaying data synthesized by said combining means;
• printing instruction means for issuing an instruction to print an image synthesized by said combining means;
• and
• recording means for storing, in said third recording medium, instruction data which designates said first contents, said second contents and data which represents a mode of combining said first contents and said second contents, in response to the instruction issued by said printing instruction means;
• and
• wherein when storing data, which specifies details of combined contents, in said third recording medium for the sake of printing by an external printing agency, said first contents themselves, protected by the predetermined right, are not stored in said third recording medium.

A contents processing control device comprising:

• first medium mounting means for detachably mounting a first recording medium including non-encrypted contents stored therein;
• second medium mounting means for detachably mounting a second recording medium;
• decryption means for acquiring encrypted contents representing encrypted first contents, decrypting said encrypted contents, and sending the decrypted first contents to a supplier of said encrypted contents;
• and
• control means for controlling a computer, detachably connected thereto and comprising means for detachably mounting a third recording medium including said encrypted contents stored therein, so as to cause said computer to serve as first selection means for accessing said first recording medium in accordance with an instruction from an operator and for selecting arbitrary second contents from said non-encrypted contents, second selection means for acquiring arbitrary contents from said encrypted contents stored in said third recording medium in accordance with an instruction from the operator and for supplying the acquired encrypted contents to said decryption means as ones representing said first contents, combining means for acquiring said first contents supplied from said decryption means, combining said first contents and said second contents in accordance with an instruction from the operator and creating combining mode data representing a combining mode, and storage means for accessing said second recording medium in response to an instruction from the operator and for storing, in said third recording medium, said encrypted contents representing said first contents, said second contents and said combining mode data.

A contents processing method comprising:

• a first medium mounting step of detachably mounting a first recording medium including encrypted contents stored therein;
• a second medium mounting step of detachably mounting a second recording medium including non-encrypted contents stored therein;
• a third medium mounting step of detachably mounting a third recording medium;
• a first selection step of selecting arbitrary contents from the encrypted contents stored in said first recording medium in accordance with an instruction from an operator, and decrypting the selected encrypted contents to generate first contents;
• a second selection step of selecting arbitrary second contents from the non-encrypted contents stored in said second recording medium in accordance with an instruction from the operator;
• a combining step of combining said first contents and said second contents in accordance with an instruction from the operator, and creating combining mode data representing a combining mode;
• and
• a recording step of storing, in said third recording medium, said encrypted contents representing said first contents, said second contents and said combining mode data, in response to an instruction from the operator.

A computer readable recording medium containing a program stored therein for causing a computer, which comprises means for detachably mounting a first recording medium including encrypted contents stored therein, means for detachably mounting a second recording medium including non-encrypted contents stored therein, and means for detachably mounting a third recording medium, to serve as:

• first selection means for selecting arbitrary contents from the encrypted contents stored in said first recording medium in accordance with an instruction from an operator, and for decrypting the selected encrypted contents to generate first contents;
• second selection means for selecting arbitrary second contents from the non-encrypted contents stored in said second recording medium in accordance with an instruction from the operator;
• combining means for combining said first contents and said second contents in accordance with an instruction from the operator, and creating combining mode data which represents a combining mode;
• and
• recording means for storing, in said third recording medium, said encrypted contents representing said first contents, said second contents and said combining mode data, in response to an instruction from the operator.

A computer readable recording medium containing a program stored therein for causing a computer to serve as:

• first selection means for selecting first contents from contents protected by a predetermined right;
• second selection means for selecting second contents from arbitrary contents;
• combining means for combining the first contents selected by said first selection means and the second contents selected by said second selection means;
• display means for displaying data synthesized by said combining means;
• printing instruction means for issuing an instruction to print an image synthesized by said combining means;
• and
• recording means for storing, in a recording medium, instruction information which designates said first contents, said second contents and data which represents a mode of combining said first contents and said second contents, for the sake of printing to be performed externally.
