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： 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.

摘要： 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.
