    摘要: A device for use in a multimedia conferencing system comprises an audio analysis processor (340), a session type classification processor (310) and a user interface controller (300). The audio analysis processor (340) is configured to analyze audio data of a communication session with multiple participating endpoints. The session type classification processor (310) is configured to determine a type of the communication session on the basis of the analysis of the audio data. The user interface controller (300) is configured to control a representation of the endpoints in a user interface on the basis of the determined type of the communication session, e.g., by sending control data (CD) to the endpoints.

    摘要: 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.

    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: 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.

    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 prioritising of data elements of a data stream for transmission to a receiving device including determining a decodability of data elements, wherein the decodability indicates the extent to which the current data element is decodable at the receiving device. Then, a priority is assigned to the data elements based on the determined decodabilities. A transmission of the data elements to a receiving device is then scheduled based on the priorities.
