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.

Video-recording and replaying apparatus, I/O scheduling method, and program

An information storing medium storing coded data of a content in segment units stores data including information of a horizontal video size, a vertical video size, a video depth, a maximum video data size in data segments, and a maximum audio data size in data segments as header information corresponding to the content. The stored data also includes information of the first frame number within a data segment, the number of frames within the data segment, and the address of each delimiter relative to the start of the data as segment information. A content reproducing apparatus can perform FIFO setting, data reading, and reproduction processing applying these pieces of information in a cache.
