Information processing apparatus, information processing methods and presentation media

An information processing apparatus comprises an extracting means (41, 42, 45) for extracting main information including first copy control information (CCI org) and auxiliary information (EMI) representing attributes of the main information from input information (IP); a generating means (50) for generating second copy control information (CCI new) based on the auxiliary information (EMI) extracted by the extracting means; and an adding means (44) for adding the second copy control information generated by the generating means (50) to the main information extracted by the extracting means. As a result, even apparatus not capable of analyzing first copy control information is capable of executing copy control.
