Abstract: Systems and methods of controlling transmissions of a media stream are provided. In one exemplary embodiment, a method performed by a media client for controlling a transmission of a media stream from a media server to the media client may include obtaining a media description of the media stream. The media description may indicate an initial stream element of the consecutive stream elements. Further, the method may include sending a request for the initial stream element. In addition, the method may include requesting, towards a control entity for a session, an establishment of the session or a modification of the session, for associating the media stream with the session. After sending the request for the initial stream element, the method may include receiving a result of the session establishment or session modification request.

Abstract: 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.

Abstract: In general, it is proposed to define techniques for managing a virtual storage volume in a cloud architecture comprising hosts which provide storage volume. The managing is achieved by checking the available virtual storage volume when a storage service request from a request interface is received. The virtual storage volume comprises at least one storage volume being assigned to the virtual storage volume. In case the storage service request can not be fulfilled by the available virtual storage volume, a request to the request interface is sent for requesting additional storage volume directly from at least one host. Upon receipt of an accept message that a storage volume fulfilling the storage service is exiting and available, the request interface initiates assigning of the additional storage volume to the virtual storage volume. As next the storage service request is executed on the virtual storage volume.

Abstract: For streaming data in a mobile communication network, a descriptive file of a stream is provided. The descriptive file comprises a list of delivery source identifiers, e.g. URIs, for unicast delivery of data segments of the stream. A broadcast indicator is selectively added to the descriptive file so as to indicate whether broadcast delivery of the data segments is available. Adding the broadcast indicator and initiating the broadcast delivery may be accomplished on the basis of a popularity of the stream.

Abstract: For streaming data in a mobile communication network, a descriptive file (100) of a stream (200) is provided. The descriptive file (100) comprises a list (110) of delivery source identifiers, e.g. URIs, for unicast delivery of data segments (210) of the stream. A broadcast indicator (120) is selectively added to the descriptive file (100) so as to indicate whether broadcast delivery of the data segments (210) is available. Adding the broadcast indicator (120) and initiating the broadcast delivery may be accomplished on the basis of a popularity of the stream.

Abstract: A synchronization device synchronizes cameras capturing a multi-view session. In particular, the synchronization device receives a respective capturing parameter for each of a plurality of individual cameras, and selects a multi-view capturing parameter, to be used in capturing a multi-view session, that matches with the capturing parameters of at least some of the individual cameras. The synchronization device selects at least two cameras, from the plurality of individual cameras, suitable for capturing the multi-view session using the multi-view capturing parameter, and notifies the selected cameras to start capturing the multi-view session at respective times using the multi-view capturing parameter.

Abstract: Synchronizing cameras, connected via a telecommunication network, for capturing a multi-view session can be controlled by a synchronization module. The synchronization module determines a multi-view capturing parameter from a capturing parameter that is received from at least one camera. The multi-view capturing parameter is provided by the synchronization module to the cameras participating in the capturing session in order to synchronize the capturing of the multi-view session. Further, a camera device informs the synchronization module of the disposability and capturing parameter of the camera. The camera receives the multi-view capturing parameter for use in capturing the session.
