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.

Session control for media stream transmission

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.

A video conference client device comprises a communication unit configured to receive a first media stream representing a recorded video conference and further configured to receive meta data related to the first media stream, the meta data representing events in the video conference, a processing unit connected to the communication unit and configured to carry out a concatenation process during which at least a part of the first media stream and at least a part of the meta data are concatenated into a video signal, and a man machine interface unit connected to the processing unit. The man machine interface unit comprises a display unit configured to display the video conference and an input unit configured to generate a video conference navigation signal. The use of the video conference navigation signal and the meta data enables a user to easily navigate through the history of the video conference.

Technique for video conferencing

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 () 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 () and a session control procedure is initiated () for a session. The media stream is associated () 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.

A video conferencing technique is described. A video conference client device implementing the technique comprises a communication unit configured to receive a first media stream representing a recorded video conference and further configured to receive meta data related to the first media stream, the meta data representing events in the video conference, a processing unit connected to the communication unit and configured to carry out a concatenation process during which at least a part of the first media stream and at least a part of the meta data are concatenated into a video signal, and a man machine interface unit connected to the processing unit. The man machine interface unit comprises a display unit configured to display the video conference on the basis of the video signal and an input unit configured to generate, based on an input, a video conference navigation signal. The processing unit is configured to control play out of the video signal in dependence on the video conference navigation signal. The use of the video conference navigation signal and the meta data enables a user to easily navigate through the history of the video conference. Additionally, a second media stream (e.g., a live stream) may be received.

The invention relates to a method for generating a personalized content file for a user entity using a file repair request for identifying a user. The file repair request is initiated by generating a preliminary file that is transmitted to the user entity, the preliminary file containing a predetermined placeholder. The preliminary file is transmitted to the user entity, the user entity starting the file repair request. The personalized content file is generated by replacing the predetermined placeholder in the preliminary file by a personalized content.

Method and device for content personalisation using file repair requests

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.

The present disclosure relates to the field of multicast/broadcast transmission of content data. A method embodiment for controlling transmission of a PTM service from a content sourceto a plurality of recipientsin a service area, wherein the service area is arranged at a higher hierarchy level and comprises a plurality of local areas arranged at a lower hierarchy level, comprises receiving location information indicating a location in the service area; determining an input traffic load of the PTM service to be transmitted to the service area; selecting the service area or a subset of one or more of the local areas contained in the service area as a destination area for the PTM service, wherein the selection is based on the received location information and the input traffic load; and controlling transmission of the PTM service to the selected destination area.

Method for controlling PTM service transmission

The invention relates to techniques for controlling a delivery of streaming content in a point-to-multipoint ('PTM') enabled network (). 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 (-) of a plurality of terminal devices (-) each receiving content via a point-to-point ('PTP') distribution (-), and initiating, following the sending of the adjustment instructions, a PTM distribution () for at least some of the plurality of terminal devices.

Control of content delivery in broadcast/multicast networks

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 () is provided to create content files associated with group rights. A device () 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.
