The STH-MD1/-C connects to a host computer via a digital 1394 interface. 
The host PC must have a 1394 port, and software to interface to the video 
stream from the camera.  This interface software presents the video stream 
from the 1394 hardware as a set of stereo frames to the user program (see 
Figure  7-1).  The STH-MD1/-C comes with interface software for either 
MS Windows 98/2000/XP or Linux.   

Before installing the software interface, the PC must be equipped with a 
1394 port.  If there is one already present, on the motherboard, then you 
can skip this section.  Otherwise you have to install a PCI or PCMCIA 
card.  The card must be OHCI compliant, which all current cards are. 

7.1.1  MS Windows Hardware Installation 

MS Windows 98SE, ME,  2000, or XP is required. 

For a PCI card, insert the card into a free PCI slot with the computer power 
off, and start the computer.  With a PCMCIA card, insert it into the 
PCMCIA slot.  In either case,  the New Hardware wizard will walk you 
through installation steps for the low-level drivers.  You may need your 
MS Windows 98/2000 CD to install some files. 

7.1.2  Linux Hardware and Driver Installation 

Linux kernels 2.4.x are required for operation.  Please see the Videre 
Design website (

www.videredesign.com/support_svslnx.htm

) for current 

information.   

Sometimes the 1394 system will get hung and you have to unhang it by     
removing all the modules, and re-installing them.  Also, the Linux IEEE 
1394 drivers sometimes do not configure the root node of the bus properly.  
Check the listing of /proc/ohci1394 to see if the word “root” appears near 
the top of the listing.  If not, you can sometimes get around this problem by 
using: 

 

modprobe ohci1394 attempt_root=1  

when installing the OHCI 1394 module. 

The STH-MD1/-C comes with interface software and several sample 
applications, including the capture application described in this manual. 

To install the software under MS Windows, execute the file 
svscap21X.exe

.  The installation process will add the relevant 

interface and application software. 

To install the software under Linux, untar the file svscap21X.tgz in a 
new directory, which will become the top-level directory of the software.  
You should also set the environment variable SVSDIR to this directory, 
and add bin/ to your LD_LIBRARY_PATH variable. 

The directory structure for the software is: 

bin/ 

     smallvcap(.exe)  
     smallv(.exe)  
     smallvcal(.exe)  
     stcap(.exe) 
     stdisp(.exe)  
     svsgrab.dll/lib
