Abstract: PROBLEM TO BE SOLVED: To achieve configurations for efficiently executing content copy or content download processing between media under strict control. SOLUTION: In content copy processing between media, identification information (media ID) of copy destination media is acquired by using an API (application programming interface) whose processing is preliminarily defined, and the acquired media ID is transmitted to a server, and copy permission information is acquired from the server, and the copy processing of content is carried out under the control of the server. Thus, it is possible to manage media as the destination of copy, and to exclude any unauthorized content use. Also, the content download processing from the server is executed according to, for example, a Java(R) program, so that it is possible to record the content in an ROM disk, and to provide it to a user.
