VIDEO-RECORDING AND REPLAYING APPARATUS, I/O SCHEDULING METHOD, AND PROGRAM

摘要

A video-recording and replaying apparatus includes a block device for use as a recording medium for video-recording and a control part, when a plurality of tasks each representing a process in regard to video-recording and replaying on the block device are executed, performing I/O scheduling on the block device by using time slices each predetermined for each of the tasks so that a total amount of I/O data for each of the tasks in each round-robin cycle for the block device is approximately equal.
