Abstract

A distributed storage system able to support real-time recording of streaming data shall be provided. Therefore, on the basis of Material Exchange Format (MXF) formatted files a data stream is packed into at least a first MXF formatted file and a second formatted MXF file. First connection data are inserted into the first MXF formatted file, wherein this first connection data points to the second MXF formatted file. Furthermore, second connection data are inserted into the second MXF formatted file, wherein the second connection data points to the first MXF formatted file. These connection data inserted as metadata into the MXF formatted files enable both seamless real-time stream recording and stream-able data playback.
