Abstract
An information processing apparatus comprises an extracting means for extracting main information including first copy control information and auxiliary information representing attributes of the main information from input information; a first generating means for generating second copy control information based on the auxiliary information extracted-by the extracting means; and an adding means for adding the second copy control information generated by the first generating means to the main information extracted by the extracting means. As a result, even an apparatus not capable of analyzing first copy control information is capable of executing copy control.
Claims14
An information processing apparatus comprising:
- an extracting means for extracting main information including first copy control information and auxiliary information representing attributes of said main information from input information;
- a first generating means for generating second copy control information based on said auxiliary information extracted by said extracting means;
- and
- an adding means for adding said second copy control information generated by said first generating means to said main information extracted by said extracting means.
An information processing method adopted by an information processing apparatus for outputting information, said method comprising:
- an extracting step of extracting main information including first copy control information and auxiliary information representing attributes of said main information from input information;
- a generating step of generating second copy control information based on said auxiliary information extracted at said extracting step;
- and
- an adding step of adding said second copy control information generated at said generating step of generating second copy control information to said main information extracted at said extracting step.
A presentation medium used for presenting a program to be executed to drive an information processing apparatus to carry out processing including:
- an extracting step of extracting main information including first copy control information and auxiliary information representing attributes of said main information from input information;
- a generating step of generating second copy control information based on said auxiliary information extracted at said extracting step;
- and
- an adding step of adding said second copy control information generated at said generating step of generating second copy control information to said main information extracted at said extracting step.
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;
- 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;
- 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:
- an extracting step of extracting main information including first copy control information and extracting second copy control information added to said main information from input information;
- a generating step of 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 at said extracting step;
- and
- a rewriting step of rewriting said first copy control information included in said main information with said rewrite information generated at said generating step of generating rewrite information.
A presentation medium used for presenting a program to be executed to drive an information processing apparatus to carry out processing including:
- an extracting step of extracting main-information including first copy control information and extracting second copy control information added to said main information from input information;
- a generating step of 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 at said extracting step;
- and
- a rewriting step of rewriting said first copy control information included in said main information with said rewrite information generated at said generating step of generating rewrite information.
