发明名称 Method for seamless real-time splitting and concatenating of a data stream
摘要 When recording packetized real-time streaming data, e.g. multimedia data, it is in general not possible to know in advance the size of the data stream, and thus the required storage area. Therefore the storage device may be full before the data stream is completely stored. The disclosed method for storing and retrieving the remaining part of the data stream on another storage device uses metadata tags (10,11) and data buffers (IB1,IB2) to split a data stream seamlessly into chunks while recording it, and distribute the chunks in real-time to different connected storage devices (D1,D2), so that the chunks can be seamlessly concatenated again in real-time for replaying the stream. The metadata tags (10,11) contain identifiers for the successive storage node (N2) and/or the preceding storage node (N1) and for the last stored application packet.
