1. A stream scheduling method for determining a timing for reading data blocks constituting real time stream data, each real time stream data being stored in a data memory device as a plurality of data blocks, in a real time stream server which sequentially reads out data blocks of requested real time stream data from the data memory device to a buffer memory device at respective reading timings, and transfers the data blocks stored in the buffer memory device to a communication path connected with a request source at respective transfer timings, the method comprising the steps of:

  • determining a reference for transfer timing which can guarantee a continuity of a stream for the requested real time stream data; and

    setting a reading timing movably within a prescribed tolerable range defined with respect to the reference for transfer timing such that the reading timing can subsequently be reallocated within the prescribed tolerable range.
