A method of controlled access to content, comprising joining an access sharing network, obtaining a content item from the access sharing network which requires access control data to enable playback, obtaining the access control data, determining from the access control data that a particular other device is authorized to play back the content item, and enabling playback of the content item in accordance with the access control data upon a positive determination that said other device is a member of said access sharing network. Preferably the access control data is used also during a predetermined period of time after making a determination that said other device has ceased to be a member of the access sharing network. Also a device () configured to carry out the method.

Method of controlled access to content

The invention relates to a method of allowing access to an authorized domain (), the authorized domain () being managed by a domain manager (), comprising a step in which a user authentication device (), which user authentication device is linked to a foreign device (), asserts to the domain manager that a local link () between the user authentication device and the foreign device is limited in distance, and a step in which the domain manager allows the foreign device to operate as a member of the authorized domain if the assertion is accepted as accurate.

Access to domain

This invention relates to a method of processing rights relating to content, that can be communicated between devices. Typically, a Digital Rights Management (DRM) system imposes limitations of use and distribution, imposed by the service provider, content provider or distributor. The method of the invention renders it possible for a user who has received DRM rights to restrict the right further. The invention is more particularly related to the receipt of DRM rights to Authorized Domain Digital Rights Management (AD-DRM) systems and the introduction of user attributed rights in the form of further restrictions introduced to the received DRM rights. The invention further relates to a Rights Program Template (RPT) facilitating the introduction of such further restrictions in a user friendly way. Finally, the invention relates to a system supporting the method of the invention.

Processing rights in DRM systems

A system (), apparatus () and method () are provided to automatically play/suggest at least one audio accompaniment while a sequence of at least one digital image is being displayed such that the audio accompaniment matches the content of the particular sequence of images and matches any provided and/or generated image metadata. Search terms are derived from the images themselves as well as any metadata provided by the user and these search terms are then used to find audio accompaniment that either (1) contains these search terms or synonyms thereof in the image or associated text (e.g., song text) or (2) represents the sound normally associated with the images, such as rushing water sound for an image of a fast flowing brook. The invention accepts user input, locates appropriate audio accompaniment as search results and presents these results to the user either by playing the audio accompaniment while displaying the images or by suggesting a playlist to the user compiled from these results.
