Abstract: A musical content utilizing apparatus has a data input portion B11, transformation process portion B13 and utilization process portion B15 implemented via programmed processes. The data input portion B11 inputs musical content data comprising different kinds of content material data about music and content definition data defining the handling of the content material data. The transformation process portion B13 transforms the content definition data in accordance with stylesheets stored in a stylesheet storage portion B14 in order to enable the utilization process portion B15 to utilize the content material data. The utilization process portion B15 generates musical tones or displays images in accordance with the input content material, providing a user with musical content. As a result, a piece of musical content is able to be shared among various different types of musical content utilizing apparatuses, i.e., various platforms.

Abstract: Client apparatus (10, 11, 12, . . . ) receives, from a server (20) or CD-ROM, content data and first management information that enables trial use of the content data and store the received content data and first management information in an HDD. When a user of the client apparatus desires normal use of the stored content data, the client apparatus (10, 11, 12, . . . ) issues a normal use request to the server (20). Then, the client apparatus receives, from the server, second management information that authorizes the normal use of the content data. Thus, only the client apparatus, to which an authorization for the normal use, is allowed to reproduce the content data in a normal mode with no reproduction function limitation on the basis of the second management information. In this way, the inventive arrangements permit efficient delivery of trial and purchasing content, but also can enhance security against unfair use, such as unauthorized copying, of the content.

Abstract: There is provided a contents processing apparatus, according to which services for use of contents can be easily controlled according to users to ensure desired security. A contents information storage stores contents, a contents management file for managing licenses for the contents, and plug-in modules for executing processing of the contents. A plug-in setting device sets plug-in modules corresponding to contents to be processed. An operation recognition device recognizes unlimited operations relating to execution of processing of the contents from the contents management file corresponding to the contents. A plug-in function permission device permits use of functions corresponding to the recognized operations among functions of the set plug-in modules. A contents processing execution device executes processing of the contents according to the functions of the permitted plug-in modules.
