摘要： 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.

摘要： Methods and devices for providing a media description of a media stream to a client are described. The client is subscribed to a media description delivery service. The media description delivery service comprises a media description delivery rule. A request for a media description delivery is sent to a media server. From the media server a media description is received. It is verified that the received media description complies with the media description delivery rule and if the verification is in the affirmative, a delivery of the media description is initiated to the client.

摘要： The invention relates to techniques for controlling a delivery of streaming content in a point-to-multipoint (‘PTM’) enabled network (100). A method aspect of such a technique comprises the steps of sending one or more adjustment instructions for achieving a buffer overlap in content buffers (132-136) of a plurality of terminal devices (102-106) each receiving content via a point-to-point (‘PTP’) distribution (116-120), and initiating, following the sending of the adjustment instructions, a PTM distribution (142) for at least some of the plurality of terminal devices.

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： 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.
