Patent ID: 7578001

Claim:
An information processing apparatus which records information signal corresponding to contents in accordance with copy control information, comprising: a path information detecting unit which detects path information embedded in the information signal and indicating information of a path through which the information signal passes; a control unit which controls recording of the information signal corresponding to the contents on the basis of the copy control information and path information detected by the path information detecting unit; and a path information adding unit which adds new path information to the path information detected by the path information detecting unit when the information signal corresponding to the contents is inputted or outputted, wherein the path information adding unit adds first and second adding path information as the new path information, wherein the first adding path information is path information of a remaining type which is not erased even if an encoding process for recording the information signal and an A/D converting process which converts the information signal corresponding to the contents from the digital signal to the analog signal are repeated by the information processing apparatus, wherein the second adding path information is path information of an erased type which is erased by repeating the encoding process and the A/D converting process, and wherein the second adding path information is added to a high frequency component of the analog signal when the information signal corresponding to the contents is outputted as the analog signal.
