11. Index Table
The following description details how the DVR manages an index table issue.
The DVR will generate a time index table indicating recorded data is kept in a particular HDD. This
allows to individually selecting recorded data to be displayed via the alarm list search and full list
search. The maximum number of lists, for a given HDD, is 3000. When the list of any given HDD is
used up-and the disk is not full, The unit will still use the rest of the space for recording. In such a
case, an index for the recent recorded data will be generated and the index of the next oldest data
will be erased so that the list does remain 3000 in total. And the next oldest data will be kept in the
index of the corresponding oldest data. For any newly-recorded data, this approach will be applied
until the disk becomes full.

In the rewrite recording mode, when the archived hard-disk drive is full, the DVR will start overwriting
the oldest data recorded. As the previous recorded data was partially overwritten by the recent
recording, the indicating time index of that data will be changed corresponding to the starting time of
the remaining session. The index of the session will be deleted from the table when it is fully
overwritten.
In the rewrite recording mode, the DVR will generate a
new index at the time returning to the TOP from the
END of HDD. In this place, the images should not be
played continuously.
