D3 Library and SDK
At the heart of the
flexibility of C_wiz is the D3 (data device driver)
architecture.
What is a D3
Current D3 Library
All D3s listed below are
included with the Evaluation Edition
Download.
As D3s are not
particularly hard to write, our intention is to provide
any D3s developed in the future by ForTotalRecall free
of charge. This statement of intent obviously can not
cover any D3s written by third parties.
All D3s have inbuilt
diagnostics tools, a 60 second trace capability and
fully utilize the C_wiz Test Drive facility to provide
context sensitive online documentation.

Frame
Grabber (LTMM)
The Frame
Grabber (LTMM) D3 saves video frame grabs
(as *.jpg files) from the video stream/s supplied to
numerous video
devices attached to a PC. Frequency, quality and
size of the video frame grabs is user definable.
Location, date and time stamps are automatically
embedded in each video frame grab to provide an audit
trail.
Possible
uses include:
o
Radar sweep
capture - many radars have an analog video out option which can
be used to drive a remote monitor - or a video capture
device.
o
Wheelhouse
monitoring.
o
Engine room monitoring.
o
Passenger
monitoring.
o
Monitoring
of patrol boat boarding operations.
To cover
the maximum possible range of video devices the
Frame Grabber (LTMM) D3 uses the Multimedia SDK (Software
Development Kit) from LEAD Technologies. To quote from
the SDK documentation, this allows the creation of
"applications that can capture from WDM, native
DirectShow including DV, Video for Windows capture
devices, control DV devices, etc", in other words just
about any video device that you could plug into
a modern PC.
The D3 has
been tested with various video devices:
o
Multi-input
frame grabbers - typically a PCI card with several BNC
or RCA connectors that will take composite video signals
from surveillance video cameras, radar etc. These sorts
of devices can typically handle up to 16 composite video
signals. Examples are the Euresys and FALCON lines.
Appropriate to use these devices when more than 2 video
signals are to be handled.
o
USB TV
tuners - typically a small in-line device with a RCA
composite video input and a USB output. Example is the
Belkin Hi-Speed USB DVD Creator. Appropriate to use
these devices when 1 or 2 video signals are to be
handled (any more and you will get USB contention
problems). These are a cheap and effective way to add a
radar sweep capture capability to C_wiz.
o
USB or
Firewire cameras - "webcams". There are any number of
possibilities here. If you attempt to use too many you
will end up with USB or Firewire contention problems.
The companion
Frame Grabber Disk Manager D3 enables a user to ensure there is always space
available
on the disk drive that contains the video frame grabs
by, if necessary, deleting the oldest in blocks of 1
hour.
This D3 is
used in conjunction with the C_wiz Video subsystem which
allows the user to view in
real-time, play or plot modes appropriate video frame
grabs completely synchronized to all the other data simultaneously captured.
