摘要： This document discloses an advantageous approach to using a digital rights management (DRM) system that is already available to an electronic device, for security and rights management in electronic ticketing transactions. Exploiting the digital rights management system, which may be a pre-existing "standardized" DRM solution, decreases the processing and memory resources needed in an electronic device for implementation of an electronic ticketing application, while advantageously gaining the proven security of established DRM systems.

摘要： A technique for protecting media content that is to be accessible via multiple media tracks of a media file is provided. A method implementation of this technique comprises the step of providing a set of one or more first layer data items that are to be accessible via a first media track, with each first layer data item being decodable to be rendered as a portion of the media content. Moreover, a set of one or more second layer data items is provided that are to be accessible via at least one second media track, with each second layer data item being decodable to be rendered in combination with at least one decoded first layer data item as an enhanced portion of the media content. With each second layer data item a track reference index is associated that allows to identify the first media track via which the first layer data items are accessible. Then, in a next step, the second layer data items and the associated track reference indices (plus optionally the first layer data items) are encrypted for being transmitted to a content recipient.

摘要： A technique for content management using group rights is described. The technique facilitates a flexible management for a group of content files mainly by effecting a change of group memberships for subsets of the group and a partial update of the content files. As one aspect, a content file manager (20) is provided to create content files associated with group rights. A device (21) is also provided to process such content files. One method aspect comprises assigning a plurality of content items to a new group whose identifier is associated with a new group rights object; determining if any of the content items has been previously distributed; and for each previously-distributed content item, creating an update content file including the group identifier of the new group and excluding the previously-distributed content item itself.

摘要： The invention provides a solution for providing a freeze-and -view-around effect from a multi-view session comprising views for a user device adapted to receive a multi-view session. The user device is adapted to request the freeze-and -view-around effect from a server while viewing a session. The server upon reception of the request from the user device generates frames of views from the multi-view session required for generating the freeze-and-view-around effect at certain time at the user side. Further the server determines also a transmission order of the generated frames and sends the frames towards the user over a unicast connection. The user device is adapted to generate from the received frames the freeze-and-view-around effect.

摘要： A technique for creating a resource in a cloud computing system is described. A method implementation of this technique comprises providing a plurality of predefined base resource descriptions, each base resource description defining a base resource in the cloud computing system and specifying one or more properties of the base resource, providing a plurality of predefined modifiers, each modifier being applicable to a resource in the cloud computing system to add, remove or change a property of the resource, wherein each modifier is associated with metrics information, and receiving a resource request indicating one or more desired properties for a target resource in the cloud computing system. In response to receipt of the resource request, a selection operation is performed to select a base resource description and one or more modifiers that are to be applied to the base resource corresponding to the selected base resource description to create the target resource in the cloud computing system, wherein the selection operation is based on the metrics information. In a next step, the selected base resource description is deployed to create the corresponding base resource in the cloud computing system, and application of the selected modifiers to the base resource in the cloud computing system is triggered to create the target resource.
