Section 3 — System Operation
KlipCache Option
A KlipCache option is available that increases the still store storage
capacity. The option consists of memory chips installed on the Still Store
module, and a software authorization code must be entered to enable
Kalypso HD/Duo KlipCache
The Kalypso HD/Duo KlipCache option increases the capacity of the cache
from 512 MB to 4.5 GB. Tables presented later in this section describe the
image capacities and animation durations this added memory supports.
HD/Duo Image File Size and Hard Disk Management
A progressive HD full raster Still Store still image requires about 2.4 MB of
storage space. An interlace HD full frame Still Store still image requires
about 5.4 MB of storage space. A video with key still image requires twice
the storage space of each above. For a full raster animated clip, each field
requires the above storage space, so HD animation files of any significant
duration will become quite large.
Table 7 shows the files sizes of full raster
images and animations.
Note Fenced images (described later) are not full raster. Using fenced recordings
reduces the storage requirements per image and improves access times.
The Kalypso HD/Duo Still Store hard disk drive has almost 40 GB of usable
image storage capacity. The number of stills or length of animation that can
be saved to disk varies. For example, the Still Store disk can hold over
16,000 full raster 720p video only stills, or over 3,600 full raster 1080i video
with key stills. Still Store disk animation capacity varies from a total of 4.5
minutes of full raster 720p video only clips, to 2 minutes of full raster 1080i
video with key clips. Approximately 38,000 full raster SD video only still
images can be stored, or about 10.3 minutes of full raster SD video with key
clips. Because the cache is smaller than the Still Store disk, all of the material
stored on disk cannot be made available simultaneously for real-time play-
back.
