Title: METHOD FOR MANAGING CONTENT DATA
Abstract:
A method for, for example, integrally handling musical contents of different formats present on one personal computer while protecting the copyright of the contents. A reproduction application (A) (311) manages the musical content distributed from an EMD server (A) (4-1). A comprehensive managing unit (315) manages musical content distributed from an EMD server (X) (4-3) and transfers it to a portable device (6-3). The format of the usage rule of the musical content managed by the reproduction application (A) (311) is different from that managed by the comprehensive managing unit (315). An EMD receiving interface (316) converts the format and handles integrally contents.
