DATA ACCUMULATING DEVICE AND METHOD, AND DATA TRANSMITTING DEVICE AND METHOD

摘要

PROBLEM TO BE SOLVED: To accumulate and reproduce voice data of multi-channels with less disks in an A/V(audio video) server corresponding to multi-channels. SOLUTION: An A/V sever 1 has HDD(hard disk device) arrays 5A and 5B, video data and voice data of Ch 1-4 are accumulated in the array 5A, and video data and voice data of Ch 5-8 are accumulated in the array 5B. In the arrays 5A and 5B, each of HDD constituting arrays is divided into a region V and a region A recording video data and voice data respectively. The region V has the constitution of RAID-3 by the arrays 5A and 5B, for example one HDD is a parity disk. The region A has constitution of RAID-1 by the arrays 5A and 5B, and voice data of each channel is doubled. When voice data of the Ch 1-4 is processed, the array 5A is used, when voice data of Ch 1-8 is processed, the arrays 5A and 5B are used.
