发明名称 DIGITAL RIGHTS CONVERSION SYSTEM
摘要 <p>The invention is based on the idea that a mechanism is introduced, by which it is possible to convert limited digital rights, which gives the proprietor of the digital rights access to the work a limited number of times, into an unlimited digital right, provided that the number of accesses associated with the limited right is sufficiently high. The present invention is advantageous since if a proprietor of limited rights associated with a digital content holds a sufficient number of limited rights, he/she is allowed to convert these limited rights into an unlimited right. The proprietor of the copyrighted content and/or the content distributor can thereby attract users to surf in to sites on the internet by in return offering limited digital rights to content, to buy media such as magazines, CDs ad DVDs to which rights are attached.</p>
