2.2
IRIX Installation: System
Identification
Performing a new installation (rather
than an upgrade) will create brand-new
LIBERTY directories in the account that
you specify. Any existing files or
directories will be erased before the new
version is installed, so be sure to back-up
anything in the account that you do not
want to lose.
Before LIBERTY can be enabled, a license key must be
obtained from Chyron Customer Support. In order to
generate this license key, Chyron Customer Support
needs your system identification number. To obtain this
number, enter the following command on your system:
sysinfo -s ↵ Enter
A unique system identifier number will be displayed.
Provide this number to Chyron Customer Support. The
Customer Support numbers are as follows:
•
•
Fax:
Voice:
(631) 845-1267
1 (888) CHYRON or
(631) 845-2132
The e-mail address for obtaining a license key is:
support@chyron.com
Chyron Customer Support will provide you with a
license key that you will need in order to enable the LIBERTY product(s) you have purchased for your system.
Entry of this license key is described later in this section.

NOTE
If you are running an older version of
LIBERTY (prior to version 6.0), you must
obtain a new license key for Version 7.1.
2.3
IRIX: Checking Available Disk Space
The available system disk space may be checked via the
df command.
Bring the mouse pointer into the confines of a UNIX
shell window and type
df -k ↵ Enter
This displays the number of 1024-byte blocks available
on your workstation’s hard disk(s).
A display similar to the following example will be
returned

The values displayed for your system will be different,
but the general format will be the same.
The number under avail indicates how much disk
space is available on each of the filesystems on your
workstation. In the above example, we see that there are
two (2) user filesystems mounted on /usr and /usr2.
We see that /usr2 has much more available space
(484152 kbytes) than /usr (67289 kbytes), so /usr2
is probably a good choice to use for the software installation in this example. Once again, this is just an example.

The point is: be sure you have enough space on the target
file system before performing the installation; otherwise,
the installation will fail.
2.4
IRIX: Setting the System Date
The system date may be checked and set via the date
command.
To check the system date, type:
date ↵ Enter
A response similar to the following will appear:
Thu Jul 31 15:03:50 PST 1997
The date may be changed if necessary. To change the
date, login as root, then type
date MMDDhhmm ↵ Enter
(Where “MM” is 2 digits describing the month (i.e. January = 01, February = 02, etc.), “DD” is 2 digits for the
date, and “hhmm” is the time, in 24-hour format (i.e.
1:03am = 0103, 2:16pm = 1416). As an example, to set
the system to 6:15pm on October 18, you would enter
date 10181815.
If a date change is required, the workstation must be
restarted.
To do this, click on System in the Desk 1 menu.
From the newly opened sub-menu, click on Restart
System.
Finally, click on OK in each of the two confirmation windows that appear.

IRIX: Running the Installation Script
The installation script for Liberty 7.1 is similar to that of
Liberty 6.0, which was updated to make installation of
the required components easier than ever. The installation script handles the installation of the following components:
•
LIBERTY Software
•
Wacom Tablet Driver
•
LIBERTY License Manager
The LIBERTY Software consists of the LIBERTY program files, fonts, filters, images, examples (animations,
backdrops, borders, brushes, filters, macros, masks, palettes, shapes, switchers), tutorials, and a few helpful utilities.
The Wacom Tablet Driver is required for LIBERTY 7.1 if
you are going to be using a Wacom tablet with your system.
The LIBERTY License Manager also is required under
LIBERTY 7.1.
The installation script handles the installation of any or
all of the above components.
2.5.1
Starting the Installation Script
We are now ready to run the installation script.
First, log in as root. If you are installing LIBERTY from
CD-ROM, CD directly into your /CDROM directory.
If you are installing LIBERTY from tape, please refer to
Appendix A for instructions on how to extract the LIBERTY distribution from tape to your hard drive. Before
Installation

Revision G
Liberty Technical Reference Manual
We can see from the previous page that there are a few
requirements which must be met before we are able to
continue with the installation script: Root privileges are
required (if you login as root then you automatically get
these privileges), IRIX 6.2 or higher is needed, and the
libraries /usr/lib/libawareaudio.so, /usr/lib/libdmedia.so, /
usr/lib/libcl.so, and /usr/lib/libvl.so must exist (these
libraries are part of the IRIS Digital Media Execution
Environment). Make sure that you have these items, otherwise the installation script will exit with an error message. In addition to these requirements, we recommend
having 100 MB of swap space for Movies. See note
below.
2.5.2
Adjusting Swap Space
When you start up LIBERTY, it informs your system as
to how much memory it requires in order to run. Your
system will reserve this amount out of the available physical memory (RAM). If LIBERTY requires more RAM
than is currently available, the system will then use a portion of your disk as supplemental memory. This portion
of your disk (the file) is known as swap space.
If LIBERTY is running very slowly at higher canvas resolutions you may need to increase your system’s available swap space. To verify this check your console
window. If it displays an "Out of logical swap space"
message during LIBERTY execution, then you need to
add to your systems current swap space.
You can add swap space to your system by using IRIX's
Swap Manager tool. The Swap Manager tool is located
in your System Manager's Administration panel. You
must be root to use the tools located on this panel. Enter
your systems root account before proceeding. As root,
choose the "System Manager" from the System toolchest.
Choose "System Admin Tools" from the Tool menu in
the System Manager window. Double click the Swap
Manager icon in the Administration panel.

If you already have a LIBERTY account on your system,
the script will warn you that this account already exists.
This is just a safety measure, because performing a “New

exists. The warning message looks like this:
WARNING:
There is already a liberty account on this system. Performing a New Installation may overwrite any existing directories and files within

If you are installing LIBERTY for the first time, or have
an existing installation that you would like to entirely
replace, select option “1” for “New installation”.
Remember that selecting this option will erase any
existing versions of LIBERTY, including the associated
image directory, from the account that you specify (later
in this script).
NOTE
The only difference between a new
installation and an upgrade is the fact that
a new installation will first erase any
existing LIBERTY items, including
associated directories, such as image, cels,
etc., (more about these LIBERTY
directories later) before installing the
software.
If you would merely like to update an existing version of
LIBERTY with the newer files from the distribution,
select option “2” for “Upgrade”.
The only real difference between selecting option “1”
(“New installation”) and option “2”
(“Upgrade”) is in the fact that option “1” begins its task
by first removing any LIBERTY-related items in the
account you specify before it installs the new ones.
Option “2” compares all of the existing files with the
new ones and only updates those which are outdated or
installs the new ones if there are no existing ones.
(Hence for an empty directory, an “upgrade” is functionally the same as a “new installation”!)
If you enter option “1” (“New installation”), the
following information will appear:
LIBERTY 7.1 can be installed into the account
of your choice, but we recommend installing the
software into a new liberty account. Accounts
are added or deleted via the User Manager tool.
Shall I bring up the User Manager for you [y] ?
Installation
13
Revision G
Liberty Technical Reference Manual
This allows you to create/delete accounts before you
select which account you would like to install LIBERTY
into. By default, the installation script will assume that
you would like to install into the liberty account unless
you specify otherwise, so this is a good time to add a liberty account if one does not already exist. Note that
using the liberty account is just a convention, not a mandate. LIBERTY can be installed into any account that
you desire.
Note that if you enter option “2” (for “Upgrade”), the
above information does not appear.
The installation then asks
Which account for installation [liberty] ?
Note that the default is liberty. Either hit ↵ Enter to
accept this default, or type in a different account name.
If all goes well, you will see
Checking for liberty account...OK
The install script then asks something like
Install software under /usr/people/liberty [y]?
The directory displayed, in this case /usr/people/
liberty, is the home directory for the liberty account.
If you created the liberty account on the /usr2 filesystem, this directory would be displayed as /usr2/people/liberty .
Hit ↵ Enter to confirm it is all right to install LIBERTY
into this directory.
The next menu to appear gives you the choice of which
product you are installing. The menu looks like

The installation script then prompts you to confirm your
selection. Depending on which product you have
selected, you will see something like
LIBERTY 32 chosen.
Is this correct [y] ?
Hit ↵ Enter to confirm your selection.
If you originally selected “New installation” for

Installation of the tablet driver is required if you are

tablet driver software included on the LIBERTY distribution tape was developed in coordination between Wacom
and Silicon Graphics, and is considered to be the standard Wacom tablet driver to use on Silicon Graphics systems.
If you don’t already have any applications on your system which use Wacom tablets, then go ahead and proceed
with the Tablet Driver installation, and skip over the following “Technical Details”. Otherwise, please read the
following section.
Installation

Revision G
Liberty Technical Reference Manual
Tablet Technical Details
The tablet driver included with the LIBERTY distribution gets
installed into your system’s kernel-level software. What this means
is that it runs as part of your system software, rather than as
another application. The tablet driver can be thought of as “sitting
in-between” your Wacom tablet and your Silicon Graphics
workstation. The tablet driver reads information coming from the
tablet and the information gets placed onto an event queue, which is
accessible to all applications (including LIBERTY) which
incorporate an interface to the system event queue (i.e. the same
tablet driver may be used by different applications). Moreover,
because information from the tablet gets placed into the standard
system event queue, the tablet is able to be used just like the mouse
would be, both within, and outside of applications. This means that
by installing the tablet driver, you will be able to use your tablet for
everything the mouse can be used for (logging in, opening the
toolchest, etc.), within certain limitations (because the tablet stylus
typically has less buttons than your mouse does).
In the past, primarily due to lack of standardization, most
applications which used graphics tablets had proprietary interfaces
to their respective graphics tablets. Some of these interfaces were
application-level interfaces, which merely means that they
interfaced directly to the applicable serial port. Others had
proprietary kernel-level interfaces. If you have one or more legacy
applications on your system which have proprietary tablet
interfaces, you will have to be particularly careful about installing
the tablet driver included with the LIBERTY distribution.
Once installed, the tablet driver included with the LIBERTY
distribution requires exclusive access to one of your serial ports (it
doesn’t matter which one). This means that the serial port cannot
be directly accessed by other applications while the tablet driver is
resident. For example, if you install the tablet driver to use serial
port 1, and you have an application which requires the ability to
open this serial port to interface to the tablet, it will no longer be
able to do so. Keep this fact in mind when deciding which port you
would like the tablet driver to use.
After selecting “Install Tablet Driver”, the installation
script prints different messages, depending on which version of IRIX you are using.

This version of the tablet driver (version 3.2 for IRIX
6.2) comes with a new tablet control panel which is used
to control a variety of tablet settings. The control panel
may be started by entering "wacom &" in a shell window.
Unfortunately, this control panel does not work well with
all tablets, especially the older SD-420 series, and its
controls can conflict with LIBERTY’s Tablet Configuration panel settings, so its use is not recommended. If you
decide to play with this panel and the cursor hangs when
using the tablet, try doing a 'Reset’ in LIBERTY's Tablet
Configuration panel. If this also doesn't work, restart
your system.

IRIX: Running Liberty from
Different UNIX User Accounts
The LIBERTY Installation Script installs LIBERTY in its
own user account (the user ’liberty’ by default). For most
applications, it is adequate to run LIBERTY out of this
account. For some applications, however, it is desirable
to allow separate UNIX users to run LIBERTY. This is
possible, but this requires a small amount of system configuration.
This is described as follows.
When LIBERTY runs, it looks for a file, liberty_paths,
in the home directory of the user running it. The file is a
human-readable text file which looks like this:
Revision G
32
Installation
CHYRON Corporation
CELS/usr/people/liberty/cels
PROJECTS /usr/people/liberty/projects
IMAGE /usr/people/liberty/image
UNDO /usr/people/liberty/undo
PLUGIN /usr/people/liberty/plugins
DOCS /usr/people/liberty/docs
This file tells LIBERTY where to find the directories for
the saved Temps, Masks, Canvas, and Animation
(CELS), the system file and saved menu configuration
files and elevators (PROJECTS), the image directory
(IMAGE), the undo buffers (UNDO) and the plugins
(PLUGIN), and the documentation directory (DOCS).
To allow another user, say ’Jim’, to run LIBERTY, login
as jim, bring up a UNIX shell window, and copy the liberty-paths file from the liberty home directory to jim’s
home directory:
cp ˜liberty/liberty_paths ˜jim
The file may then be edited so that when Jim runs LIBERTY, it uses different directories for CELS,
PROJECTS, IMAGE, and UNDO (these paths can also
be changed using the User Set-up button in the Dir panel
of the Config environment in LIBERTY - see the LIBERTY Artist’s Manual for details).
In addition to the above, LIBERTY needs to know where
the sys directory is. This is controlled by an environment
variable, LIBERTY-SYS. To set this for Jim, login as
jim, open a UNIX shell window, and type the following:
setenv LIBERTY_SYS ˜liberty/sys
Installation
33
Revision G
Liberty Technical Reference Manual
(This assumes that LIBERTY was installed under the
user ’liberty’). The above command can be added to the
user’s cshrc file, so that it runs when the user logs in.
Permissions may also be a problem when running LIBERTY as a different UNIX user. The user running LIBERTY must have all permissions on the sys directory, and
the directories specified in the liberty_paths file. For
example, to set permissions for the sys directory, login as
liberty and type the following in a shell window:
chmod 777 sys
chmod 777 sys/*
Once the above is set-up, jim can run LIBERTY from a
shell window:
˜liberty/sys/paint32
This can be further automated by adding the path of the
LIBERTY sys directory
to jim’s ’path’ environment variable. Normally, the path
environment variable is set in the user’s cshrc file (in the
user’s home directory). By editing this file in a text editor, the path of LIBERTY’s sys directory can be added to
the path setting. An example of a path setting in the
cshrc file might look like this after editing:
set path=(. ˜liberty/sys ˜/bin /usr/sbin /usr/
bin /usr/local/bin /usr/bsd /bin)
Note that the path of the LIBERTY sys directory has
been added after the ’.’ in the path setting.

IRIX: Liberty Menu Font
The font used for LIBERTY’s menus is configurable via
the ’LIBERTY_FONT" environment variable. The font
used by recent versions of Liberty is
"-sgi-screen-bold-r-normal-*-*-140-*-*-*-*-*-*"
Two fonts used in previous versions of Liberty were
"*palatino-bold-r-normal--*-120-*"
and
"-*-helvetica-bold-r-normal-*-*-110-*-*-*-*-*-*"
Obviously, these fonts have a grammar which is quite
complex, however, there are tools which make the selection and preview of fonts much easier. One of these tools
is "xfontsel’. Typing this command brings up a window
which can be used to select and preview fonts. Try playing with the tool to preview the fonts mentioned above.
Using "xfontsel", it is easy to select a different font.
The only requirement is to make sure the font is small
enough to be used in LIBERTY’s buttons.

Place the cursor in this shell window and hit the
middle mouse button. This "pastes" the font selection
after the previously-typed double-quote.

[ ] 6.
Type another double-quote into the shell window,
then hit return. For example, the shell window will
appear something like:
setenv LIBERTY_FONT "-*-helvetica-bold-r-normal-*-*-110-*-*-*-*-*-*-"
before you hit return.
[ ] 7.
Run LIBERTY or LIBERTY Paint from this shell
window. LIBERTY’s menus will use the desired font
IF it exists on the system. If the selected font does
not exist on your system, the default font will be
used.
If the font change is to be permanent, add a line like
the one above,
setenv LIBERTY-FONT "-*-helvetica-bold-r-normal-*-*-110-*-*-*-*-*-*"
to the .cshrc file in the LIBERTY home directory
using "jot" or the other editor of your choice.

Introduction
This section is applicable to Liberty artists who use
Wacom tablets as input devices. Skip this section if you
intend to use only the mouse.
§3.2 through §3.7 explain the hardware set-up and connection of the WACOM tablet to the Silicon Graphics
workstation.
§3.8 through §3.10 discuss the same topics as they apply
to Windows NT workstations.

IRIX: Supported Tablets And Drivers
The Wacom tablet driver used by LIBERTY 7.0 is compatible with all Wacom tablets. For the latest versions of
Wacom Tablet drivers, visit the Wacom web site at (http:/
/www.wacom.com).
NOTE
The Wacom tablet driver used by LIBERTY 5.0 and above can be configured to
use either serial port 1 or serial port 2
(this differs from earlier versions of LIBERTY, which always expected the tablet
to be plugged into serial port 1). Make
sure that your tablet is plugged into the
same serial port that the tablet driver is
configured to use, otherwise the tablet will
not work. See “Tablet Driver Installation” on page 20 for more details on
installing the Wacom Tablet Driver
included with the LIBERTY distribution.

IRIX: WACOM Tablet Cables
If you purchased your system and tablet through Chyron,
the correct tablet cable will be shipped with your system,
and you may skip this section.
It is important to have a cable designed for Wacom tablets attached to your system, as most standard serial
cables used for modems, etc. will not work. Additionally, different Silicon Graphics platforms have different
serial port requirements, so it is important to have the
correct cable for your specific system and tablet requirement.
The correct cables may be purchased through Wacom at
1-800-922-6635. When ordering, be specific about the
Silicon Graphics system and Wacom tablet that you currently have.
Orders for Silicon Graphics systems, tablets, and cables
may also be made through CHYRON. Please contact us
if you would like for us to put a package together for you,
at 1-516-845-2132.

IRIX Only: DIP Switch SettingsSD Series
In order for the system to recognize an SD-series tablet as
its pointing device, the DIP switches must be set properly. The switch settings shown here are for both the
Model SD-4XX Series and the SD-510C Digitizing Tablets.
The switches on the SD-4XX Series tablets are located at
the rear of the tablet.
The switches on the SD-510C are located on the right
side of the tablet. To gain access to these switches,
remove the small rectangular cover held in place by a single phillips screw.

NOTE
The following DIP switch settings are different than the ones specified for pre-LIBERTY 5.0 versions.
The following
recommended settings are now equivalent
to the factory defaults for the SD-series
tablets.
3.5
IRIX: Configuration SettingsUD Series
There are no dip switches for the newer UD-series tablets. These tablets are configured via the system to operate at their factory defaults. If the UD series’
configuration soft keys are inadvertently changed, turn
the tablet off, then back on, then restart the system. This
will allow the Tablet Driver to properly reconfigure the

Liberty NT relies on the WACOM Control Panel to configure the Tablet for both the UD series and Intuos type
tablets. The tablet is configured by Liberty through software to the current settings for the Control Panel in these
cases. If the UD or Intuos Tablet configuration is Inadvertently changed, turn the tablet off, then back on, then
restart the system. This will allow the Tablet Driver to
properly reconfigure the tablet.
For the SD series tablets, it is necessary to configure DIP
switches on the Tablet as well. Refer to section 3.4 of this

[ ] 7. The imported image should fill the Region window
without blanking ("black") visible on the left or right
sides. Errors can be corrected by using the RGB Input’s
Horizontal Phase slider to match the input signal’s
sync to that out of the Centaur. If an oscilloscope is
unavailable, the slider may be adjusted as follows:
•
Grab a frame into the Frame Buffer by clicking
on its Live Video and then Freeze Frame buttons.
•
Click on the Screen button in the title bar and
then double-click on its Import to Region
selection.
•
Observe the error. If blanking is visible on the
right, move the Horizontal Phase slider to the
right. If it is visible on the left, move the slider to
the left.
•
Repeat the above steps until the image is against
the edge of the screen region.
[ ] 8. If noise appears in the image in the form of "sparkles" or
the signal does not match that of the one being sent to it,
the RGB Input needs to be aligned using its Ref+, Refand Contrast Adjust controls.
While this procedure can be "roughed" without an
oscilloscope, one is recommended for proper operation of
the video adapter:
•
Connect a color bar signal to the RGB inputs of
the video adapter.
•
Starting with green, use an oscilloscope to compare the adapter's RGB Input and RGB Out signals.
•
The "sparkles" are caused by the Ref- adjustment being set too high. Click on the Frame
Buffer's Live Video button and adjust the slider
down until the noise disappears. The black level
error introduced will be corrected in the next
step.

recorders. In performing these procedures you will
•
Configure both the workstation and disk recorder
for network operation
•
Confirm that communication exists between the
workstation and disk recorder
•
Configure LIBERTY to recognize the disk
recorder as one of its video sources
•
Set LIBERTY's canvas resolution to meet the
needs of a specific project.
At this time, ethernet control of the following disk
recorders is supported by LIBERTY:
• Abekas A60
• Àccom RTD 4224
• Abekas A65

Also, at this time, SCSI control and video of the following disk recorders is supported by LIBERTY:
• Àccom WSD
• Àccom Xtreme
• Accom 2Xtreme
• Pronto Video
• SDL QuickFrame/
Diskcovery
• ProntoVision
• SDL HD1.5+
SCSI Video Only is supported for these devices with control available only via Ethernet.
• Abekas A65/A66
• Abekas Diskus
NOTE
The following note applies only if
configuring the SDL HD1.5+ or
HD360.
Because the HD1.5+ is actually four
separate SCSI devices, LIBERTY
must be set to HD1080i (1920 x 1080)
or HD720p (1280 x 720) resolution in
order to recognize it AND the device
must be configured as a QuickFrame/
Diskovery, not an HD1.5+.
If you are using the HD360, which
effectively turns the HD1.5+ into a
single SCSI device, then configure
the device as an SDL HD1.5+ as
usual, and use any appropriate (e.g.
16:9) LIBERTY resolution.
As each disk recorder is slightly different, network configuration specific to an individual unit follows the procedure for configuring the workstation.

Video Boards and DDRs
CHYRON Corporation
4.6.1
Configuring Workstation for Ethernet Operation
In order for the workstation running LIBERTY to communicate with the disk recorder, each device must know
the other’s IP (Internet Protocol) Address.
The IP Address is a four byte number expressed as four
decimal numbers separated by dots, 89.0.1.45 for example. The first pair of numbers (89.0) represent the network number and the second pair (1.45) is the local
address. All machines on the same local network should
have the same network number but different local
addresses.
As the workstation and the disk recorders have different
factory default network numbers, they must be changed
to give both the same network number. The workstation’s
network number may be obtained and changed, if necessary, as follows:
[ ] 1. Login to the workstation as root.
[ ] 2. From the Desk 1 menu, click on Desktop. From the
newly opened sub-menu, click on Unix Shell.
[ ] 3. Selecting Unix Shell creates the outline of a box
attached to the mouse. Click the box down where you
like and it will become solid.
[ ] 4. Bring the mouse pointer into the confines of the shell
window and type
uname -n ↵ Enter
to determine the hostname for your
workstation. Note the name for later use.
If your workstation is to be added to an
existing network, its network number
Video Boards and DDRs
23
Revision G
Liberty Technical Reference Manual
should match that of the other devices and
its local address should be unique.
4.6.2
Choosing Disk Recorder IP Address
Remembering that the disk recorder and workstation
should have similar network numbers but unique local
addresses, choose an address for the disk recorder. To
ensure that you do not use an address that has already
been assigned on your network, you should review the
addresses of existing hosts. The procedure for this follows.
[ ] 1. Bring the mouse pointer into the confines of the shell
window and type
more /etc/hosts ↵ Enter
to view the list of existing hosts and their
addresses.
[ ] 2. Press the Space Bar on the keyboard to page through
the list of hosts.
Notice that the lines beginning with a pound sign (#) are
comments, not operative lines. The operative addresses
are only the lines that do not begin with #.
[ ] 3. Noting the existing host addresses, choose a unique IP
Address for the disk recorder and write it down.
[ ] 4. Refer to procedure for setting the IP address of individual
DDRs.
If you have more than one workstation on your local network, you may need to check the /etc/hosts file on
each workstation.
Revision G
24
Video Boards and DDRs
CHYRON Corporation
4.6.3
Adding New Hosts
To add new hosts you will edit the file that lists the current hosts. You will use an easy-to-use text editor called
Jot. Take care when editing this file, because if you
change part of the file unintentionally, it may interfere
with the proper operation of your network.
The basic procedure for editing the /etc/hosts file with
Jot is as follows (Note: you must be superuser):
[ ] 1. Type:
jot /etc/hosts ↵ Enter
The file appears in a window. It looks like
the hosts file that you looked at in the
previous step.
[ ] 2. Cursor down to a line in the file where you want to insert
the new address.
[ ] 3. Hit the Enter key to open a new line.
[ ] 4. Cursor to the new line and type in the new IP address,
keeping in mind the rules listed above.
[ ] 5. When you have typed in the new address, click on File,
then click on Save, then click on Exit.
Your modified /etc hosts file is saved with the new
address.

IRIX: Configuring Workstation for SCSI
Operation
Before using a SCSI device, the device must be assigned
a unique SCSI address. There are two ways to determine
which SCSI device address to use.
Video Boards and DDRs
25
Revision G
Liberty Technical Reference Manual
4.7.1
Using a Unix Shell to locate a SCSI
device number:
[ ] 1. Open up a unix shell by selecting the IRIX Desktop>UnixShell menu option.
[ ] 2. Type the command, "hinv" on the command line. This
command will print a hardware inventory of all of the
devices that your system recognizes. The SCSI devices
are identified similar to the lines that follow, depending
on your system configuration:
Integral SCSI controller 0: Version WD33C93B, revision D
Disk drive: unit 5 on SCSI controller 0
Disk drive: unit 4 on SCSI controller 0
Disk drive / removable media: unit 2 on SCSI controller 0
This inventory shows us that our SCSI
controller number is 0, and that three SCSI
devices exist on the bus. Those devices
are numbered 5, 4, and 2.
[ ] 3. See step 4, below.
4.7.2
Using System Manager to Locate a
SCSI Device Number:
[ ] 1. Select the System menu from the main Desktop menu on
your workstation.
[ ] 2. Select the ’Disk Manager" from the System submenu.
The disk manager lists the SCSI devices that are
connected to your system. The SCSI devices are labeled
"SCSI Disk 0,x", where x is the device number assigned
to the SCSI devices connected to your system.
[ ] 3. See step 4, below.
[ ] 4. Choose a number that is currently unused as a SCSI
device. The number must be between 3 and 7, since
lower numbers are generally reserved for system and
internal SCSI devices. Generally, it is best to select the
Revision G
26
Video Boards and DDRs

highest possible available device number, since some
DDRs require that their device have the highest SCSI
address.
NOTE
The procedures that follow are for
individual disk recorders.

Revision G
Liberty Technical Reference Manual
Some versions of A60 firmware anticipate
a three digit number at the end of the
address and, if one isn’t used, will fill in
trailing zeros. In the example above, the
final “2” would be filled out to become
“200” resulting in an address of 89.0.200,
not 89.0.0.2. If this problem occurs,
simply enter the final number with leading
zeros. For example, to assign 89.0.0.4, the
sequence is as follows:
89.0 ENTER 0.004 ENTER
[ ] 3. Turn the disk recorder off and then back on again. The
system will reboot with the new Ethernet IP Address.

round-trip (ms) min/avg/max = 0/2/10
Revision G
42
Video Boards and DDRs
CHYRON Corporation
Your disk recorder’s hostname and IP Address may be
different then that shown. While the transmit time may
vary, the packet loss should be zero. Loss would denote
physical network problems such as a faulty transceiver or
cabling.
A response similar to the following would indicate connection problems:
PING A60 (89.0.0.2): 56 data bytes
----A60 PING Statistics---5 packets transmitted, 0 packets received, 100% packet loss
A response similar to the following would indicate that
the hostname is incorrect (possible mistyped):
/usr/etc/ping: a60: Unknown host
Connection and hostname problems should be corrected
before continuing.

SGI: Setting Canvas Resolution
Digital disk recorders store images in CCIR 601 format.
This format does not provide for square pixels common
to SGI workstations. CCIR 601's resolution is 720 x 486
in NTSC and 720 x 576 in PAL. This results in NTSC
Revision G
54
Video Boards and DDRs
CHYRON Corporation
images appearing compressed vertically on the workstation monitor while PAL images appear stretched vertically.
LIBERTY provides a means to get around this problem.
Images can be interpolated to the correct resolution so
that they appear with the same aspect ratio at the disk
recorder as they are on the workstation’s graphic monitor.
When the canvas resolution is set to Default 720, as
long as the Interpolate feature and the correct frame
rate are enabled, LIBERTY will compensate for the disk
recorder’s rectangular pixels.
The frame rate selection (30 fr/s NTSC, 25 fr/s PAL) is
found under the Canvas Configuration Panel.
Rescale with interpolation options can be found in the
Defaults menu in the Canvas Configuration panel.
As would be expected, bringing an image into the workstation from a disk recorder, interpolating it to correct for
the pixel difference and then writing the image back to
the disk recorder while reversing the interpolation would
cause the image to be degraded somewhat. Multiple
reads and writes of the same image would amplify this
degradation causing it to "soften."

Misc
Most of the Input settings can probably be left at the
default values. However, if you are using PAL timing
instead of NTSC, this can be changed with the "Jack
Timing" radio button from the Timing tab.
Also, the "Signal Present" radio buttons will tell you
whether there is a video signal present on the video input.
If no signal is present, the "None" button will be selected,
otherwise either "NTSC" or "PAL" will be selected
depending on the video input signal timing.
The Output settings have a useful function to determine
whether the Video Output is functioning properly or not.
Under the "Misc" tab, select the "Output Test Colorbars"
check box in order to display color bars to the video output. Remember to uncheck this box after testing, because
as long as its checked, no other video will be output but
bars.
Also in this tab, you can specify whether the video output
is in full color or black & while alpha, using the "Jack
Carries" radio buttons. Liberty always send Alpha out to
the video, so if the option is set to "Alpha", you will see a
black & white image corresponding to the Alpha values
in Liberty's canvas.

Configure LIBERTY to recognize the disk recorder as
one of its video sources. Set LIBERTY’s canvas resolution to meet the needs of a specific project.
At this time, Ethernet control of the following disk
recorders is supported by LIBERTY:
• Àccom Xtreme
• Àccom WSD
• Accom 2Xtreme
• SDL Diskcovery
• ProntoVideo
As each disk recorder is slightly different, network configuration specific to an individual unit follows the procedure for configuring the workstation.
Also, at this time, SCSI control of the following disk
recorders is supported by Liberty:
Accom WSD/
Xtreme/2Xtreme
SDL
QuickFrame/Diskcovery
SDL HD1.5+ (HDTV)
Pronto Video
Pronto Vision (HDTV)
NOTE
The following note applies only if
configuring the SDL HD1.5+ or
HD360.
Because the HD1.5+ is actually four
separate SCSI devices, LIBERTY
must be set to HD1080i (1920 x 1080)
or HD720p (1280 x 720) resolution in
order to recognize it AND the device
must be configured as a QuickFrame/
Diskovery, not an HD1.5+.
Video Boards and DDRs
65
Revision G
Liberty Technical Reference Manual
If you are using the HD360, which
effectively turns the HD1.5+ into a
single SCSI device, then configure
the device as an SDL HD1.5+ as
usual, and use any appropriate (e.g.
16:9) LIBERTY resolution.
4.14.1
Configuring Workstation for Ethernet Operation
In order for the workstation running LIBERTY to communicate with the disk recorder, both devices must know
one another’s IP (Internet Protocol) Address.
The IP Address is a four byte number expressed as four
decimal numbers separated by dots, 89.0.1.45 for example. The first pair of numbers (89.0) represent the network number and the second pair (1.45) is the local
address. All machines on the same local network should
have the same network number but different local
addresses.
As the workstation and the disk recorders have different
factory default network numbers, the DDR’s must be
changed to the same network number as the workstation.
[ ] 1. Locate the folder where your Windows NT software is
installed, using Windows NT Explorer. This folder is
most commonly known as “WINNT”; however, its
name on your system may be different.
[ ] 2. Open the System32 folder.
[ ] 3. Open the Drivers folder.
[ ] 4. Open the Etc folder.
[ ] 5. Double-click the file named “Hosts”. The “Open With”
dialog box will open, asking you to select an application
with which to open (and possibly edit) this file. Using the
scroll bar in the “Open With” window, select the program
Revision G
66
Video Boards and DDRs
CHYRON Corporation
“NOTEPAD”. Click the “OK” button or double-click the
“NOTEPAD” icon.
You will need System Administrator privileges to add the
IP address of the Digital Disk Recorder.
Using NOTEPAD to edit this document, add the IP
address of the DDR at the bottom of the existing list,
under previous entries. Press <.
Save the file and close it.
4.14.2
Configuring Workstation for SCSI
Operation
Prior to using SCSI devices with Liberty, the Advanced
SCSI Programming Interface (ASPI) software must be
installed. The ASPI for Win32 toolkit comes on the Liberty CDROM, and can be installed when Liberty is
installed. You can run the ASP[ application "aspichk.exe"
from the Liberty CD-ROM to determine whether or not
ASPI is already installed on your system.
Before using a SCSI device, the device must be assigned
a unique SCSI address. Use the following procedure to
determine what SCSI devices are in use by the system, in
order to determine the free devices.
[ ] 1. Bring up the Control Panel as follows: click Start ->
Settings -> Control Panel.
[ ] 2. Double click on the "SCSI Adaptors" icon.
[ ] 3. There should be at least one SCSI adaptor listed under
the "Devices" tab. If not, there is no SCSI Adaptor
installed in your system, consult your SCSI Adaptor's
Owner's Manual for instructions on how to install a SCSI
Adaptor driver.
[ ] 4. Assuming there is a SCSI Adaptor entry, either click on
the "+" to expand the entry, or double-click on the entry.
Video Boards and DDRs
67
Revision G

The attached SCSI devices should then be visible.
Double clicking on a device will bring up the Properties
display for that device. Click on the "Settings" tab, and
locate the Target ID. This is the unique SCSI identifier
for that device.
[ ] 5. Find a SCSI Target ID that is not in use, and assign this
device to the DDR using the following procedures unique
to each DDR.
4.14.2.1
Sierra Design Labs QuickFrame/
Diskcovery
[ ] 1. Using the SDL DDR trackball, select "SCSI Target" from
the Main Menu.
[ ] 2. Change the SCSI ADDR with the trackball to the SCSI
device number selected in the steps described on page 318, "Choosing a SCSI Address".
Holding down the middle button while rolling the trackball allows you to change the address.
[ ] 3. Select the "Execute" menu option. Change the "Confirm
No" entry "Confirm Yes". (The Monitor will display
"SCSI Target Mode").
[ ] 4. Reboot the NT workstation.
[ ] 5. Verify after rebooting that the workstation recognizes
that the SDL QuickFrame/ Diskcovery is on the SCSI bus
by following the above procedure.
4.14.3
Accom WSD (Xtreme, 2Xtreme, etc)
[ ] 1. Using the Accom’s keyboard, select "Remote" from the
Main Menu.
[ ] 2. Change the SCSI ADDR with the keyboard to the SCSI

[ ] 4. Reboot the NT workstation.
[ ] 5. Verify after rebooting that the workstation recognizes
that the Accom WSD is on the SCSI bus by following the
above procedure.
4.14.4
ProntoVideo
Unlike most DDR’s, the SCSI ID can easily be changed
on the ProntoVideo by means of a switch on the back of
the machine, similar to an external disk drive. The ID
should be changed only when the device is powered off.
The ProntoVideo can then be powered up, followed by
the NT workstation.
4.14.5
ÀCCOM WSD, Xtreme & 2Xtreme
Disk Recorders
The following describes the steps required to configure
Àccom WSD or Xtreme Disk Recorders for use with
LIBERTY. Refer to Appendix A.5 WSD Ethernet Port

[ ] 3. Select the correct Ethernet port (BNC or AUI) using the
F8 Net Access key on the WSD Mini Keyboard.
[ ] 4. Assign the disk recorder a unique IP Address using the
WSD Mini Keyboard to enter the digits. The network
number should match that determined in §4.14.1 (89.0 in
the example shown). The local address (0.2 in the
example) should be a unique number.
For example, to assign 89.0.0.2, the sequence is as
follows:
89 . 0 . 0 . 2
Press the appropriate function key to store
the address, and the information is written
to disk.
[ ] 5. Turn the disk recorder off and then back on again. The
unit will reboot with the new Ethernet IP Address. With
newer DDRs, use the Reset function.
This completes ethernet configuration for the WSD or
Xtreme disk recorders. Before configuring LIBERTY for
disk recorder operation, perform the Confirming Disk
Recorder Connection procedure that follows.
4.14.5.2
Confirming Disk Recorder Connection
Before using the disk recorder within LIBERTY, you
should confirm that it is a recognized remote device and
physically connected to the local network. The following
procedure uses the Windows NT ping command to
test the recorder's connection.
[ ] 1. Enter the DOS Shell.
[ ] 2. At the prompt, type ping a60 and press <
The correct number of pings (5) is the default, and five
packets of test data are sent to the disk recorder.

4.16
NT: Setting Canvas Resolution
Digital disk recorders store images in CCIR 601 format.
This format does not provide for square pixels common
to NT workstations. CCIR 601’s resolution is 720 x 486
in NTSC and 720 x 576 in PAL. This results in NTSC
images appearing compressed vertically on the workstation monitor while PAL images appear stretched vertically.
Revision G
78
Video Boards and DDRs
CHYRON Corporation
LIBERTY provides a means to get around this problem.
Images can be interpolated to the correct resolution so
that they appear to the workstation’s graphic monitor with
the same aspect ratio that is output to the disk recorder.
When the canvas resolution is set to Default 720, as
long as the Interpolate feature and the correct frame
rate are enabled, LIBERTY will compensate for the disk
recorder’s rectangular pixels.
The frame rate selection (30 fr/s NTSC, 25 fr/s PAL) is
found under the Canvas Configuration Panel.
Rescale with interpolation options can be found in the
Defaults menu in the Canvas Configuration panel.
As would be expected, bringing an image into the workstation from a disk recorder, interpolating it to correct for
the pixel difference and then writing the image back to
the disk recorder while reversing the interpolation would
cause the image to be degraded somewhat. Multiple
reads and writes of the same image would amplify this
degradation causing it to "soften."

Loading LIBERTY New Release Distribution Tape
LIBERTY v6.0’s standard distribution method is on CDROM. However, tape distribution is available for those
customers lacking a CD-ROM drive on their system.
Please contact Chyron Customer Service department at
(516) 845- 2132 if you need a distribution on tape.
This section describes how to extract the files from the
compressed tape distribution.
[ ] 1. You must be logged in as root. If not, login as root and
open a UNIX shell window now.
[ ] 2. Select a directory to extract the contents of the tape into.
/usr/tmp or /usr2/tmp is a good choice, depending upon
your particular system configuration, but any empty
directory will be fine, as long as there is enough free
space on the filesystem in which the directory exists.
NOTE
You will need about 300 MB of space
to extract the full contents of the
distribution tape.
[ ] 3. The cd command is used to change directories. Go to
the desired extraction directory by typing
cd dirname ↵ Enter
where dirname is your desired extraction
directory. For example, if you would like
to extract the tape into /usr/tmp you would
type cd /usr/tmp ↵ Enter.
[ ] 4. Insert the LIBERTY Installation Tape into the tape drive.
In addition to the LIBERTY program, this tape contains
demo animation files (including their associated images),
Revision D
2
Appendix
CHYRON Corporation
fonts, filters, Wacom Tablet Driver software, and
LIBERTY License Manager software.
[ ] 5. Extract the contents of the tape by typing
tar xv ↵ Enter
The names of files being extracted will
appear in the shell window, for example:
xinstall,485 bytes, 1 block
xliberty/.Sgiresources, 24 bytes, 1 block
xliberty/.alias, 772 bytes, 2 blocks
If no error messages appear during the tar process, return
to Section 2.5.1, "Starting the Installation Script". If error
messages do occur, refer to the section called "Dealing
with Tape Extraction Errors" later in this section.
A.3
Loading Patches and New Releases
A.3.1
Loading Executable LIBERTY Tapes
LIBERTY releases come in the form of Patches and New
Releases. Patches are no-charge revisions that remedy
existing problems or contain minor enhancements to
LIBERTY. New Releases are versions of LIBERTY that
add new features, improve its attributes, capabilities or
usability, and may also include corrections. Both
Patches and New Releases are provided at no charge
within the initial warranty period or during the period of
an Extended Support Agreement.
While New Releases are distributed in a compressed file
format requiring the install program, Patches are usually
distributed in an uncompressed, executable form. Patch
tapes normally contain seven executable files
(liberty32, liberty64, paint32, paint64, Playmovie,
Appendix
3
Revision D
Liberty Technical Reference maNual
menu.bin and help.bin) that need to be loaded into
LIBERTY’s sys directory. The procedure for loading
these files follows.
[ ] 1. Login to the workstation as liberty, or whatever user
account LIBERTY has been installed into.
[ ] 2. From the Desk1 menu, click on Desktop. From the
newly opened sub-menu, click on Unix Shell.
[ ] 3. Selecting Unix Shell creates the outline of a box
attached to the mouse. Click the box down where you
like and it will become solid.
[ ] 4. Within the newly-opened shell, type
cd sys ↵ Enter
[ ] 5. Insert the LIBERTY Installation Tape into the tape drive.
[ ] 6. Load the contents of the tape into the “sys” directory by
typing
tar xv ↵ Enter
[ ] 7. The names of the executable files being loaded will begin
to appear in the shell window. The procedure takes
about one to two minutes. When the prompt reappears
the transfer is complete.
If problems are encountered in extracting the tape, follow
the procedure DEALING WITH TAPE EXTRACTION
ERRORS found later in this section.
A.3.2
LIBERTY Warning Messages
You might find that some executable versions of LIBERTY generate a list of “warning” messages in either the
LIBERTY Message Window or in the shell that LIBERTY was started from. Messages to the shell, normally
Revision D

Appendix
CHYRON Corporation
suppressed in released versions of LIBERTY, are generated by most non-release executable versions of LIBERTY, such as Beta versions.
If present, these messages are intentionally left in by
Chyron software engineers to diagnose and correct certain problems which might occur. While some are listed
as “error” or “warning” messages, these messages do not
necessarily indicate a problem. Most are inserted into the
code by a programmer to print a message to the shell
about a particular function’s current state.
A.4
Installing LIBERTY Beta Software
A.4.1
Beta Software Notes
Before a LIBERTY Update or New Release is distributed to customers, Beta releases of it are tested by Chyron West engineering and demo artists. Occasionally, a
customer who has reported a problem or provided input
for a new feature will be sent a Beta release to test the
changes.
As Beta releases are meant as test versions of LIBERTY,
not all features may be fully operational. Because of this,
when installing beta software, it is recommended that the
released version of LIBERTY be retained and the beta
copy be loaded into a separate directory.
A.4.2
Creating/Linking the Beta Directory
The LIBERTY Beta software release is distributed on
tape as an abbreviated version of the New Release software. The Beta release tape contains an install script,
LIBERTY executables, the license manager, and tablet
drivers. It contains only a subset of the full release
image directory, and does not include any tutorials or

demo examples. The license manager and tablet driver
are provided for first time LIBERTY users, and generally
won’t be necessary for existing users of LIBERTY
To install the Beta release, follow the instructions in the

The LIBERTY Beta software in the libbeta account will
have its own images, cels, undo, projects, and plugin
directories. However, you may want to reference the
same images as you do when running your released copy
of LIBERTY. To accomplish this, edit the liberty_paths
file in the Beta user home directory, and change the
IMAGE path from the Beta home directory to the LIBERTY home directory:

You will need to set the protection properties on the
shared directory and files. The following command
allows other people to read, write, and execute the files in
the image directory:
cd ~liberty
chmod -R +rwx image
exit
Now, whenever you log into your LIBERTY Beta
account, you can run LIBERTY from the toolchest, and
access the same Liberty images as your main LIBERTY
release does.
A.5
Dealing with Tape Extraction Errors
Problems that may occur with tar usually fall into two
categories: tape device recognition and byte swapped
archives. The following procedure addresses both of
these problems.
[ ] 1. Display the installed tape devices from the hardware
inventory table by typing
hinv -ctape ↵ Enter
[ ] 2. Take notice of the information for the tape drive(s). It
will be displayed in a manner similar to one or both of the
following lines:
Tape drive:
Tape drive:
Tape Drive:

unit 3 on SCSI controller 0: DAT
unit 5 on SCSI controller 1: QIC 150
unit 6 on SCSI controller 1: 8mm (8500)
1. 3)Note the unit number and SCSI controller number for
the drive from which you are installing LIBERTY. Type the
following command substituting your controller and unit
numbers:
[ ] 3. For example, if the above DAT drive (unit 3, controller 0)
were to be used, the command line would be
Appendix
9
Revision D
Liberty Technical Reference maNual
tar xvf /dev/mt/tps0d3 ↵ Enter
[ ] 4. If the Step 3 did not succeed and a byte swapped error
was returned, add the non-swap extension (ns) to the
command. Still substituting your controller and unit
numbers, type
tar xvf /dev/mt/tps0d3ns ↵ Enter
[ ] 5. For example, if the above QIC 150 drive (unit 5,
controller 1) were to be used, the command line would be
as follows:
tar xvf /dev/mt/tps1d5ns ↵ Enter
[ ] 6. Recent versions of IRIX have introduced a "swap"
extension, replacing "ns" with "s." If the above
command did not work, this new extension may be
necessary. Still substituting your controller and unit
numbers, type
tar xvf /dev/mt/tps0d3s ↵ Enter
[ ] 7. Again using the QIC 150 drive as the example, the
command line would be as follows:
tar xvf /dev/mt/tps1d5s ↵ Enter
[ ] 8. If you are still experiencing problems, contact Chyron
West Customer Support for assistance. Call (408) 9882285 between the hours of 8AM - 5PM Pacific Time.
A.6
LIBERTY RAM Requirement
The amount of RAM required to run LIBERTY is determined by canvas resolution, the number of Fast Temps
and Fast Masks enabled and the workstation’s IRIX version.
Revision D
10
Appendix
CHYRON Corporation
LIBERTY’s Paint Environment provides six temporary
picture storage buffers called Temps. The current Temp
buffer is always kept in RAM for fast access, hence the
term Fast Temp. Operators may configure LIBERTY
for up to six Fast Temps with the remaining buffers saved
as disk files. Each of these Temp buffers hold the full
RGB and Alpha information for each pixel on the Canvas. If you are using LIBERTY PAINT 32 or LIBERTY
32, the information stored requires 32 bits per pixel. If
you are using LIBERTY 64 or LIBERTY PAINT 64, the
information stored requires 64 bits per pixel.
Similar to the Temps, LIBERTY provides six temporary
Mask buffers that may also be assigned to RAM for
faster access. Masks saved to RAM are referred to as
Fast Masks. As with Temps, the buffers not assigned to
RAM would be saved as disk files. Each Mask buffer
contains 8 bits of data for every pixel on the Canvas. (If
you are using LIBERTY 64 or LIBERTY PAINT 64,
each mask buffer contains 16 bits of data per pixel.)
Fast Temp and Fast Mask buffers are used within the
Animation Environment for compositing into individual
elements. While most animations only require two Fast
Temps and one Fast Mask, if multiple switcher, mask, or
morph actors are layered on top of one another, this
requirement will increase.
LIBERTY 32’s and LIBERTY PAINT 32’s RAM
requirements, in megabytes (Mb) may be approximated
using the following formula:
({[4 + (4 * FT) + FM] * Xres * Yres}/1,048,576) + 20
Mb + 25 Mb
The formula allows for 4 bytes/pixel of Canvas data plus
4 bytes/pixel for each Fast Temp (FT) plus 1 byte/pixel
for each Fast Mask (FM) multiplied by the Canvas resolution. This is divided by 1,048,576 to convert the can-
Appendix
11
Revision D
Liberty Technical Reference maNual
vas/buffers requirement to Mbytes. Finally, the base
requirements for the LIBERTY application (20 Mb) and
for IRIX (25 Mb) are added.
The base requirement for IRIX is an estimate which can
vary widely from system to system. In addition, shells,
the SGI desktop tools, and other running processes consume memory above the base requirement. SGI UNIX
tools such as ps, osview, and gr_osview can be utilized to get a better feeling for your system’s requirements.
For LIBERTY 64 and LIBERTY PAINT 64, the RAM
requirements may be approximated using the following
formula:
({[8 + (8 * FT) + 2 * FM)] * Xres * Yres}/1,048,576) +
43 Mb + 25 Mb
This formula differs from the formula for LIBERTY 32
and LIBERTY PAINT 32 since the base requirement for
the LIBERTY application is larger, and because the
images consume twice the space.
For example, for LIBERTY 32 and LIBERTY PAINT 32,
a Canvas resolution of 2,000 x 2,500 with three Fast
Temps and two Fast Masks, the RAM requirement is calculated as follows:
({[4 + (4 * 3) + 2] * 2,000 * 2,500}/1,048,576) + 45 Mb
= 131 Mb
For LIBERTY 64 or LIBERTY PAINT 64, the same configuration requires:
({[8 + (8 * 3) + (2 * 2)] * 2,000 * 2,500}/1,048,576) + 68
Mb = 240 Mb
Revision D
12
Appendix
CHYRON Corporation
The tables on the following pages show LIBERTY’s
RAM requirement (in Mbytes) for typical canvas resolutions. The amounts shown are approximate, and will
vary depending on which hardware platform is being
used and which IRIX version is being used.

Using a Disk Array with LIBERTY
•

•

•
Megadrive Enterprise
NOTE
Refer to the specific disk array
instructions for connecting the array
to the SGI workstation.
A.8
Disk Array Interface Introduction
Liberty can use the speed and capacity of a RAID disk
array in combination with one of SGI’s fast video boards
to allow the storage of video in real-time.
There are several models of RAID arrays supported by
Liberty, including those made by Ciprico, Megadrive and
Eurologic.
A.8.1
Ciprico Setup
The Ciprico 6900 is connected to the SGI through SCSI.
Because the Ciprico requires a very fast SCSI connection
(called "differential SCSI") and most SGI’s have a slower
SCSI (called "single-ended SCSI"), some kind of adaptor
card or hardware is needed between the SGI and the
Ciprico.
Appendix
13
Revision D
Liberty Technical Reference maNual
There are a couple of choices for this hardware. One is
an adaptor card (either EISA or PCI) which fits into the
SGI and provides a direct SCSI connection to the
Ciprico. This card can be purchased directly from
Ciprico (http://www.ciprico.com).
Another option is the Paralan SCSI converter box which
is a piece of hardware which sits between the SGI and
the Ciprico. It basically converts the single-ended SCSI
of the SGI to the differential SCSI of the Ciprico. The
model number we have is Model SD16B. This can be
purchased from Paralan (http://www.paralan.com/
sd10.html).
Once the connection between the SGI and the Disk Array
is made, the disk must be set up. Ciprico has tools available to do this, which can be downloaded from their website via FTP. The latest version as of this writing is:
ftp://ciprico.com/pub/Software/Spectra2.3.tar
Liberty uses the Ciprico as an XFS filesystem, so the disk
array needs to have at least some (if not all) of its available space formatted as an XFS filesystem. This means
that Liberty treats the Ciprico as just another SCSI disk,
where any type of files can be stored. The Ciprico utility
’cutil’, which is a part of the Spectra tools mentioned
above, can be used to partition the disk.
A.8.2
Other Disk Array Setup
Most other RAID disk arrays do not require special SCSI
interfaces to the SGI workstation. These come equipped
with standard "single-ended" SCSI which can directly
connect to the SGI’s internal SCSI bus.
Revision D
14
Appendix
CHYRON Corporation
A.8.3
Liberty’s Interface
The Disk Array can be used by Liberty to quickly store
video to disk or retrieve video from disk. It can also be
used to play back video from the disk through an appropriate video board (either Impact, Octane or O2 video at
this time).
There are two menus in Liberty’s Paint environment for
interfacing to disk arrays. These are accessed by the
Grab and Show buttons in the Transfer menu. Clicking
on the corner button brings up the appropriate menu.
The Grab popup menu has been totally changed to allow
grabbing from video directly to the disk array. The
"Video To Disk" button changes the mode of the Grab
button to allow grabbing video directly to a disk array.
Otherwise, video is grabbed to Liberty’s canvas.
The "File" and "Frames" buttons specify the name and
number of frames to grab. All the grabbed video will be
stored in a single file - a "clip". There are 10 elevators
for storing different file names.
The Show popup menu has new additions much like
those in the Grab popup. The "Disk To Video" button
turns on showing of video from a disk array. The "File"
and "Frames" buttons are the same as in the Grab popup,
except that the "Frames" value is updated to reflect the
number of frames in a clip that has been opened.
A.8.4
Grabbing
To record a clip, bring up the Grab popup, click on the
"Video To Disk" button, enter the filename you want to
save the clip as (the file must be on the XFS filesystem
on the disk array), and enter the number of frames you
want to record. Then, bring down the popup and hit the
Grab button. Liberty will tell you to
Appendix
15
Revision D
Liberty Technical Reference maNual
"Left Click, Spacebar or Return to grab; Right
Click or Esc to abort"
The incoming video will be written to disk once you left
click, for as many frames as you specified. There is some
delay before the actual transfer starts, however, so be sure
to click a little before the video you want. There are no
provisions for triggering the start of the grab from an
external source.
Once the video is grabbed to disk, it is available as if it
were a Disk Path VTR, so the VTR panel can be used to
assign this clip to a Disk Path, and can be grabbed from
at a particular timecode.
A clip file can also be created through the VTR interface.
Merely setup a Disk Path VTR, change the save-as type
to "RAW .yuv" and render out to this device. The saved
clip is then treated as a video file and can be displayed
through the video, as described below.
A.8.5
Showing
To play a clip, bring up the Grab popup, make sure you
are in "Realtime Show" mode, click on the "Disk To
Video" button, enter the filename of the clip you want to
play. The "Frames" button is automatically updated to
the number of frames in the clip, based on the size of the
file. Then, bring down the popup and hit the Show button. The clip will be played through the video device all
the way through to the end.
The clip can also be played through the File Manager
interface. Bringing up the File Manager and browsing
any saved clips, you can see that they have the VTR-type
controls available (H < <| |> > T). These controls can be
used to play the clip interactively through the video
device directly from the disk array.
