3. Setting up and Configuring the SceneLink Application
The current chapter goes through the hardware and software installation before
the scene camera option can be used. It also contains trouble shooting
information on the common problems in using the SceneLink application.
3.1 System Requirements
The following items are required to perform a scene camera EyeLink experiment
with the SceneLink application:
•
A VGA overlay device (AVT-3170 Scan Converter, i.e., “Overlay Box”)
supplied by SR Research, including necessary cabling.
•
Scene cameras (with cables and power supply) supplied by SR Research.
•
An advanced digital video converter (Canopus ADVC 55, 100, or 110),
including the necessary cabling (a IEEE 1394 cable and a S-Video or
composite video cable). Power supply is also supplied for ADVC 100/110
converter and for ADVC 55 converter if a laptop is used as the display
PC. Please note that ADVC 100 or 110 is required for scene camera
recordings with audio.
•
A fast display computer (2.0 GHz or faster CPU and at least 512 MB
RAM) with two large hard disks installed. One of the hard disks (120 GB
or more disk space with 7,200rpm) is solely devoted for scene camera
video saving, as we need about 1 Gigabyte of hard disk space for each 5
minutes of video recording. Note that the hard disk must be de-
fragmented and preferably formatted in NTFS file system with the largest
block size.
•
The display computer must also have a reasonably good video card
installed with at least 64 Megabyte of video memory. Known supported
video cards include ATI 9500 Radeon and nVidia GeForce4 MX 400.
Known unsupported ones include WildCat high end ones.
•
The display PC must has a 6-pin or 4-pin firewire 1394 port (and driver
for it if required).
•
If you want to record audio data as well, make sure you have a good
microphone and an amplifier.
