Abstract: A technique for controlling a play-out of a media data stream at a receiving device is provided. The media data stream comprises one or more programs, and each program comprises one or more program components. In a method implementation of the technique, a zone description is defined. The zone description is defined for a media zone for at least one program or at least one program component in the media stream and identifies the media zone for the at least one program or the at least one program component. In a next step, the zone description is associated to a program specific information data segment. The program specific information data segment is part of the media stream and comprises data specifying information at least regarding to the at least one program or at least one program component. The method also comprises transmitting the media data stream towards the receiving device.

Abstract: 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.

Abstract: 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.

Abstract: A method for controlling the transmission of a media stream comprising a plurality of consecutive stream elements Is described. The method comprises the step of obtaining (32) a media description of the media stream, the media description indicating an initial element of the stream elements. A request for the initial stream element is sent (34) and a session control procedure is initiated (36) for a session. The media stream is associated (38) with the session in the session control procedure. The transmission of a subsequent element of the stream elements is controlled in accordance with a control rule of the session. Devices and further methods embodying the invention are also described.
