ESTIMATING RECORDING TIME
When using the Timer Program, there may be instances where, because of maximum re-
cording fields, image quality, and audio recording settings, there is insufficient recording
space on the unit’s hard disk drive to complete the recordings as programmed.
When the maximum recording fields setting differs in the Normal Rec Setting menu and
Timer Program menu, the possible recording duration will differ from the duration displayed
in ESTD TIME field in the Normal Rec Setting menu.
When setting the timer for multiple programs, refer to the
DX3009 Recording Time Tables
section or
DX3016 Recording Time Tables
section to confirm the amount of hard disk
space the recording duration will take up under different setting conditions.
Using the Timer Program settings below as an example of estimating possible recording dura-
tion, the chart below shows that everything is recorded on the sixth day, and on the seventh
day only 1.1% of Program 2 content is recorded on the hard disk drive. (Conditions: Image
Quality is set to HIGH, Audio Recording is set to OFF, built-in 30 GB hard disk drive.)
The cal-
culation is derived as follows: Program 1 uses 5.3% of the disk space per day. In six days it
uses 31.8% (5.3 times 6). Program 2 uses 10.3% per day or 61.8% in six days (10.3 times 6).
In six days 93.6% of the disk space has been used (31.8 plus 61.8). This leaves 6.4%
available at the beginning of day seven. After Program 1 finishes recording only 1.1% is left
for Program 2 (6.4 minus 5.3).
