Abstract
A system for storing video data may include at least one file. The at least one file may include a data cluster including a plurality of data blocks, each data block storing at least some of the video data, and/or a plurality of first pointers sequentially arranged and respectively indicating the plurality of data blocks. The at least one file may be used for time-shifting and recording functions. If the at least one file is used for the time-shifting function, the system may delete contents of the first pointers in a circular manner so that the system sequentially deletes the contents of at least some of the first pointers and/or if the system sequentially deletes the contents of a first pointer that is located last in the arrangement, the next first pointer whose contents are to be sequentially deleted is a first pointer that is located first in the arrangement.
