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.

Abstract: A technique is disclosed for controlling data packet transmissions from a server to a client having a client buffer in accordance with a waiting mode and a dynamic mode. The waiting mode is performed before packets containing data encoded subject to a current bit rate have reached the client buffer; the dynamic mode is performed otherwise. In the waiting mode, down-switches to lower bit rates are allowed but up-switches to higher bit rates are disabled. In the dynamic mode, up-switches and down-switches are both allowed, with adjustments in the bit rate of packets controlled based, in part, on the amount of data contained within the client buffer when packets containing data encoded subject to the current bit rate first reached the client buffer. The two modes help avoid unnecessary rate switches.

Abstract: A Mixer and a Method for providing media streams towards a plurality of endpoints, the media streams originating from one or more media source(s). Within the method at least a first request set of a first endpoint of said plurality of endpoints and a second request set of a second endpoint of said plurality of endpoints are received, whereby a request set comprises information relating to at least a subset of one or more codec parameters, and whereby a request set pertains to a media stream, whereby said first request set and said second request set pertain to a same media content. The received first request set and second request set are aggregated into an aggregated request set pertaining to a first media source. Thereafter one or more media stream(s) according to said aggregated request set are requested from said first media source.

Abstract: A technique for distributing in a multicasting network media content via two or more media layers is described. The media layers are hierarchically arranged in accordance with a scalable coding protocol such as the Scalable Video Coding (SVC) protocol. In a method implementation of this technique, in a first step a first number of media recipients for a first media layer that is transmitted via a first bearer of the multicasting network is determined. Then, a second bearer of the multicasting network for at least one second media layer is selected taking into account the first number and a hierarchical relationship between the first media layer and the second media layer.

Abstract: In a multi-view autostereoscopic display system (100) a plurality of views (120,122,124,126) is displayed repeatedly within a plurality of adjacent viewing cones (107,111,113), where pairs of views among the plurality of views form stereoscopic view pairs. A first set of depth adaptation settings, e.g. baseline and disparity, and at least one further set of depth adaptation settings, e.g. baseline and disparity, are obtained, the at least one further set of depth adaptation settings is different from the first set of depth adaptation settings. The first set of depth adaptation settings is then set for a first subset of views among the plurality of views in all viewing cones. The at least one further set of depth adaptation settings is set for at least one further respective subset of views among said plurality of views in all viewing cones.

The short-term key may be a Traffic Encryption Key, TEK, and the long-term key may be a Service Encryption Key, SEK.

Abstract: To control content delivery to plural clients (6) of a mobile communication network (1), a network entity (5) of the mobile communication network (1) collects geo information of the plural clients (6) and evaluates the collected geo information of the plural clients (6) based on a rule to determine whether the content delivery is to be adapted. The network entity (5) identifies a region for which the content delivery is to be adapted. The network entity (5) selectively outputs a message (9) to a controlling entity (10) if it is determined that the content delivery is to be adapted. The controlling entity (10) controls the content delivery in response to receiving the message (9), to adapt the content delivery for clients located in the identified region.

Abstract: This invention relates to a method for streaming a media file to an end user using a hypertext transfer protocol HTTP, wherein a proxy monitors HTTP messages for detecting a streaming of the media file using HTTP. When a HTTP message is received, the proxy determines bearer parameters required for streaming the media file and determines whether a bearer meeting an appropriate service quality is necessary. If necessary, the proxy triggers a provision of the bearer meeting with said appropriate service quality.

Abstract: The invention provides a solution for synchronizing cameras connected via a telecommunication network for capturing a multi-view session controlled by a synchronization module. The synchronization module provides a multi-view capturing parameter determined from capturing parameter received from the at least one camera. Said multi-view capturing parameter is provided to the cameras participating in the session capturing in order to synchronize the capturing of the multi-view session. Further a camera device is proposed which inform the synchronization module about its disposability and about the capturing parameter of the camera. Said camera receives a multi-view capturing parameter which is used for capturing the session.
