DIGITAL RIGHTS MANAGEMENT SYSTEM

摘要

A digital rights management system defines a domain of digital access devices (16) for which decryption information is provided collectively for accessing content data. A joining digital access device (16) is joined to the domain when the domain already includes a joined digital access device (16). The joining process comprises detection of user approval action at a user input interface (21) of the joined digital access device (16). In the case of approval an enabling message is transmitted from the joined digital access device (16) that is indispensable for joining of the joining digital access device (16).
