Information processing apparatus, information processing method and presentation medium including copy protection data from a non-compliant apparatus

An information processing method adopted by an information processing apparatus for outputting information, said method comprising the steps of:

• extracting main information including first copy control information and auxiliary information representing attributes of said main information from input information, said auxiliary information indicating at least whether an apparatus that recorded said main information did not recognize and process said first copy control information;
• generating second copy control information based on said extracted auxiliary information if said auxiliary information indicates that said apparatus that recorded said main information recognized and processed said first copy control information;
• and
• adding said generated second copy control information to said extracted main information.

A presentation medium used for presenting a program to be executed to drive an information processing apparatus to carry out processing including the steps of:

• extracting main information including first copy control information and auxiliary information representing attributes of said main information from input information, said auxiliary information indicating at least whether an apparatus that recorded said main information recognized and processed said first copy control information;
• generating second copy control information based on said extracted auxiliary information if said auxiliary information indicates that said apparatus that recorded said main information did not recognize and process said first copy control information;
• and
• adding said generated second copy control information to said extracted main information.

An information processing apparatus comprising:

• an extracting means for extracting main information including first copy control information and extracting second copy control information added to said main information from input information, said second copy control information indicating at least whether an apparatus that recorded said main information recognized and processed said first copy control information;
• a third generating means for generating rewrite information used for rewriting said first copy control information included in said main information in accordance with said second copy control information extracted by said extracting means if said second copy control information indicates that said apparatus that recorded said main information did not recognize and process said first copy control information;
• and
• a rewriting means for rewriting said first copy control information included in said main information with said rewrite information generated by said third generating means.

An information processing method adopted in an information processing apparatus for outputting information, said method comprising the steps of:

• extracting main information including first copy control information and extracting second copy control information added to said main information from input information, said second copy control information indicating at least whether an apparatus that recorded said main information recognized and processed said first copy control information;
• generating rewrite information used for rewriting said first copy control information included in said main information in accordance with said extracted second copy control information if said second copy control information indicates that said apparatus that recorded said main information did not recognize and process said first copy control information;
• and
• rewriting said first copy control information included in said main information with said generated rewrite information.
