The last few weeks we have been implementing a very
unique feature for the
RealCap module. The RealCap is one of the new corner stones in the APAS system enabling
you to capture video in real-time directly to the computer hardrive. Previously we needed
to have external equipment to enable video capturing at 60 images/sec. Now we
that the system prices is lower and the functionality is high.
Real time capturing of video the images from the
camcorder/VCR has to be continuously supplied to the computer. Meaning that when the
capturing process is in progress the VCR or camcorder has to be in Play mode. Initiating
the VCR or camcorder into play mode induces a small positioning problem which
compensated using computer control VCR's or a nicely featured trimming process.
Trimming is used to cut the captured video sequence to only
contain the actual images of interest. If the VCR or camcorder is not controlled
computer a large amount of images has to be captured in order to ensure that the sequence
of interest is part of the captured video. Using a computer controlled VCR or camcorder it
is possible to position the VCR or camcorder just before the start of the sequence, and
during the capturing process the VCR or camcorder is automatically put into play mode.
This method decreases the amount of video needed to be captured.
In the first version of the RealCap the use of AG-5700,
AG-7350 and the BCD AG2550 was supported. In order to keep up with the fast growing
consumer electronic market we implemented support for the RealCap to control camcorders
and VCR's through the new serial connection from SONY
called LanC which
is the most widely used communication for
View the current supported
camcorders and VCR's under LanC
What is LanC
The LanC is a serial connection between the computer and
the camcorder or VCR that requires a special cable and communication software to work. The
software is incorporated in the RealCap and therefore
invisible to the user. The
functionality from the RealCap is simple VCR commands like Play, Stop, Pause, Fast Rewind,
Fast Forward, Search Rewind, Search Forward, Step +/-.
The cable that connects the VCR or Camcorder to the computer is a special design.
The communication is done through a single wire and therefore
there has to be some
additional electronics incorporated within the cable.
FAQ about the LanC
How does the LanC affect my work ?
Capturing video using a synchronization
process shortens the
time of analysis. The amount of video captured is minimized and the trimming process is
easy and fast.
Do I need the LanC in my laboratory ?
More and more equipment is sold with the support of the
LanC connection. This means that the LanC gives you a broader range of equipment to choose
from. Just check out the current list maybe you even got
LanC ready equipment in you laboratory or try look for the following symbol on you VCR or
camcorderthis will indicate that your
equipment is LanC ready.
I still have the old AG-5700/AG-7350 from Panasonic
do I need the LanC
The RealCap supports the AG-5700 and the AG-7350 from
Panasonic so there is no need to get the LanC right away.
