Abstract: There is provided mechanisms for determining a time offset for a video segment of a video stream using metadata. The metadata comprises time information of at least one of a start time and an end time of the video segment. A method is performed by a video network node. The method comprises extracting a first video part and a second video part from the video stream. Each of the first video part and the second video part comprises a common video segment. The method comprises identifying a sequence of video frames in the first video part that represents the common video segment. The method comprises determining the time offset based on a time difference between an end-point frame of the Identify sequence of video identified sequence of video frames and the time information in the metadata.

Abstract: A distributed stream processing system including a plurality of storage devices, at least one of which is configured to process at least one segment of a data stream, thereby producing a changed segment of the data stream, and provide output of at least the changed segment of the data stream, and a server configured to accept the output of the storage devices and combine the output into a transport stream. A method for combining a plurality of data streams including using one or more storage devices for processing at least one segment of a data stream, thereby producing a changed segment of the data stream, and providing output of at least the changed segment of the data stream, and combining the output of the storage devices into a combined data stream. Related apparatus and methods are also described.

Abstract: A method of processing video data. During a preprocessing stage a plurality of video content datasets in a storage network node, the method calculates coefficient data and encoding decisions of said video content dataset on a per frame basis, said encoding decisions comprising at least some of frame sizes, motion vectors, macroblock quantizers and macroblock layouts partitions (geometry), deleting said coefficient data; storing said encoding decisions in an auxiliary file associated with said video content dataset; during an operative stage: receiving from a client terminal via a communication network a request for streaming a first of said plurality of video content datasets; identifying a respective said auxiliary file associated with said first video content dataset; and utilizing said encoding decisions from said respective auxiliary file to recalculate said coefficient data of said first video content dataset without recalculating a respective said encoding decisions.
