1. Introduction
VideoLab is a video option for the IRIS-4D/GTX, IRIS-4D/VGX,
IRIS_4D/VGXT, and SkyWriter graphic workstations. VideoLab
enables you to view high-resolution images from the
workstation in low-resolution video formats, capture low-
resolution images in real time and view them on the high-
resolution workstation monitor, and blend this low-
resolution input with the workstation-derived imagery for
low-resolution output, in a range of component video
formats.

2. Configuration_Information
Installing the VideoLab software creates the
/usr/gfx/ucode/vof/vli and /usr/video/vli directories.
The vli.sw.demos image installs buttonfly menu files into
the /usr/demos directory, which are useful only if the
standard eoe2.sw.demos subsystem (which contains the
buttonfly executable) has already been installed.
To configure the demos to run in 525/60 Hz timing or 625/50
Hz timing, a system defaults button has been provided to
allow you to establish the default operation of the demos on
your system (you must be logged into the demos account to
have the proper write permissions on the setup file). The
demos will default to the 525/60 Hz mode as shipped.
The VideoLab breakout box provides several connectors which
are intended for future expansion; these include those in
the areas labelled LOOP and VTR CNTRL OUT (with the
exception of the sync loop through connectors), and the
composite video connectors labelled COMP and S-VIDEO in the
areas labelled IN and OUT.
VideoLab does not provide an integral VideoMedia V-LAN
transmitter. Instead, we have provided several programs
that provide an interface to the RS-232 based VideoMedia V-
LAN transmitters. These programs comprise a portion of the
vlan232 image. In particular, the executable vlan232cmd and
the shell script vlan.demo are installed to
/usr/video/vlan232/bin. The vlan.demo script provides an
example of how to use a VideoMedia device control network
with the VideoLab to produce frame-by-frame animation.
Certain demos require particular hardware configurations;
the demos test to see if the hardware capability is present
and if it is not, they exit with an error message detailing
the requirement. For example, the motion tracking demo spot
requires an alpha bitplane option.
