Video and the audio record which use file segmentation in order to maintain the data integrity critical

摘要

Method and the system which make the loss of the critical data smallest, are written to record medium, (figure 1A, 32). Critical dejitarudeta, is written to digital recording medium with small block or the segment, (figure 1A, 20). As for the aforementioned segment when it is transferred to memory medium, the file allocation table is renewed, can close the file (figure 1A, 24). The critical data quantity which is lost the file by the segment doing, as the result of system breakdown or power source loss in smaller file segment is decreased. While playing back, the file segment is assembled dynamically, with continual method makes the playback of the digital data possible.
