  • Patent number: 7389035
    Abstract: In a stream processing system, a stream partitioned by a prescribed time interval is extracted as a partial stream, from one or more real streams formed by continuous time series data, according to playback position information or timestamps of the real streams, and a virtual stream is produced by concatenating one or more partial streams so as to enable a continuous playback. Then, a stream partitioned by another prescribed time interval is extracted as a partial virtual stream, from the virtual stream, according to playback position information or timestamps of the virtual stream, and a meta information related to a content of the partial virtual stream is stored in relation to the partial virtual stream.
