Distribution System of Contents Embedding License Machine ID
First Claim
1. A digital content usage system usable with a content usage apparatus, said content usage apparatus for use of a digital content containing a license machine ID, the system comprising:
- an acquiring section that acquires a unique machine ID of the content usage apparatus;
a detecting section that detects, from the digital content, the license machine ID;
a comparing section that compares the acquired unique machine ID with the detected license machine ID; and
a determining section that permits the content usage apparatus to freely use the digital content if the acquired unique machine ID matches with the detected license machine ID,and restricts the content usage apparatus to a temporary use of the digital content within a time duration if the acquired unique machine ID does not match with the detected license machine ID.

Abstract
A server apparatus operates a content sale site for selling a digital content and connects communicably via a communication network to a client apparatus which may purchase a digital content for use in an electronic music apparatus. In the server apparatus, a communicating section communicates with the client apparatus for receiving therefrom order information specifying a digital content to be purchased, and machine ID information designating machine IDs of electronic music apparatuses which are intended to use the specified digital content. A licensing section embeds the received machine ID information in the digital content specified by the client apparatus so as to license the specified digital content to the electronic music apparatuses designated by the client apparatus. A providing section provides the digital content embedded with the machine ID information to the client apparatus such that the provided digital content is made available exclusively by the designated electronic musical apparatuses according to the embedded machine ID information.
