Abstract: PROBLEM TO BE SOLVED: To easily store data in a storage device by identifying plural zones of different data transfer rates, identifying the data transfer rate of every zone, and then storing the zone data based on the identified transfer rate of every zone. SOLUTION: This process decides the minimum transfer rate to the disk zone in a storage device which stores the video data (S400). Then the video rate requested by the video data is decided (S402), and a system overhead constant K is offered (S404). The number N of simultaneous parallel streams is calculated from Km/V (S406). For instance, the transfer rate (m) is set at 5 megabytes/sec against a single zone together with the video rate V set at 3 megabytes/sec, and the constant K set at 8.85 respectively. Under such conditions, the number N of simultaneous parallel streams is set at 11.3. Therefore, a specified zone can support 11 video streams.
