Abstract: A method and a system for managing sharing of a video in a collaboration session are disclosed. A sharing function obtains (B122) a synchronization time stamp of an audio frame of the collaboration session, wherein the audio frame is going to be used for synchronizing the shared video stream with the collaboration session. The sharing function determines, based on a video frame rate difference between the desired frame rate and a source frame rate of the video file, whether more, less or same number of video frames as in the video file are needed in the shared video stream. The sharing function iteratively retrieves (B140) video frames from the video file stored in the storage function (140). The sharing function provides (B160), by the sharing function (112), the shared video stream by sending said one or more generated video frames to the video communication service (110).

Abstract: Methods and systems, including computer software products, for providing a shared digital video stream. Primary digital video streams are collected from at least two digital video sources. The primary digital video streams are time-synchronised with respect to a common time reference. The time-synchronised streams are analysed to detect at least one pattern selected from a first set of patterns. The shared digital video stream is produced as an output digital video stream based on consecutively considered frames of the time-synchronised streams and the detected patterns. The output digital video stream is continuously provided. The synchronisation introduces latency, which gets included in the output digital video stream. The pattern detection includes considering information of the primary streams that is present in a later frame than a frame of a time-synchronised primary stream yet to be used in the production of the output stream.

Abstract: Method and systems for managing sharing of a video in a collaboration session. A central server obtains a synchronization time stamp of an audio frame, relating to the session, to be used for synchronizing the shared video stream with the session. The central server determines, based on a video frame rate difference for the video file, whether more, less or same number of video frames are needed, and sets up a buffer for provisioning the shared video stream to the session. The central server iteratively retrieves video frame by video frame of the video file and generates zero, one, or more video frames according to the determination, with a desired resolution, while setting a time stamp of each generated video frame corresponding to the desired frame rate. The shared video stream is provided by inserting the generated video frames into the buffer.

Abstract: Methods and systems, including computer software products, for providing a shared digital video stream. Primary digital video streams are collected from at least two digital video sources. The primary streams are individually analysed to detect at least one event. The primary streams are time-synchronised with respect to a common time reference. The time-synchronised primary streams are analysed to detect at least one pattern. The pattern detection is based on the detected event, firstly, video and/or audio information in at least two time-synchronised of the primary streams considered jointly or, secondly, video and/or audio information in a single primary stream spanning across at least two detected events. The shared stream is produced as an output digital video stream based on consecutively considered frames of the time-synchronised primary streams and the detected patterns. The output stream is continuously provided to a consumer of the shared digital video stream.

Abstract: The present invention relates to methods and apparatuses for allocating time slots to circuit-switched channels established to comprise one or more respective time slots in a recurrent frame of a time division multiplexed network. According to the invention, a time slot allocated to said channel is associated with a selected level, of at least two available levels of priority. Decisions as to whether or not to deallocate said time slot from said channel is then based upon a comparison of said selected level of priority and a level of priority associated with a request for a time slot for another channel.
