Thanks, Rich. Just for completeness, I've included the newest Galatea
announcement file, as there a slight changes. I wasn't sure what was
appropriate as far as reposting info that I had posted some months ago,
so I guess I erred on the vague side. This is probably overdoing it,
but at least it's not a flame war...
Anyway, I'm not trying to force this stuff down anyone's throat, but I
do want to make sure that it's existence is known.
As always, all comments except "Why didn't you implement dynamic
rebinding of virtual outputs?" are perfectly welcome.
Also, there is probably a tremendous overlap in readership between
comp.multimedia and comp.ivideodisc. As Galatea is really a video
device control and management system, not a multimedia package or
platform, it probably makes sense to deal with it only on
comp.ivideodisc, so this is the last crosspost I'll do.

=======
The Galatea Network Video Device Control System is a package for
controlling and managing video resources in a distributed workstation
environment. The system handles the control of video devices, such as
analog video disc player/recorders and analog video routing switches.
Galatea runs on 4.3BSD and System V UNIX on 32 bit workstations.
Galatea is available for the public under the same copyright
restrictions as the X Window System. Any person may copy and use
Galatea for any purpose, as long as the M.I.T. copyright is maintained
on all copies of the distributed software. To obtain a copy of
Galatea, anonymous ftp can be used to media-lab.mit.edu (Internet
18.85.0.2). The Galatea distribution, in tar(1) format, as well as
PostScript and line printer copies of the documentation are available
in the subdirectory 'galatea' The documentation is present in the
distribution, so there is no need to grab both. If you cannot form an
ftp(1) connection to media-lab.mit.edu, I would be happy to send mail
containing uuencoded versions of either the documentation or the
distribution. If you don't specify whether you want the PostScript or
lineprinter version of the documentation, I will send the lineprinter
version. I don't have the time or energy to send any of this
information via US mail. I can send the documentation non-uuencoded,
if that is better.
There is no official support for Galatea, although I try to keep
things going and I respond to complaints about bugs. If you wish to
use the system, feel free, but the responsibility is in your hands. I
want to hear about real bugs in the system, and take efforts to
correct them. As I have graduated, the future of Galatea development
is uncertain. As the Media Laboratory is not a product development or
support organization, Galatea is only being offered unofficially by
me, not by the lab.
Currently, Galatea supports Sony, Pioneer and Digital Equipment
Corporation video disc players, the Panasonic write-once units, the
NEC PC-VCR, Akai Digital Patch Panels, and many switches produced by
Presentation Environments. I welcome any device driver software that
other users develop and would be more than happy it to add to the
distribution. The system runs on 4.3BSD, Ultrix, Interactive 386/ix,
HP-UX, SVR4 and Sun OS.
The client library is device independent, so the clients never need to
be aware of the type of device under control. In addition, the physical
location of a device is hidden from a client, so in a distributed
environment, a video disc player may be anywhere. Galatea servers can
communicate to each other to share resources. There need not be a
single server, but a hierarchy can be created, allowing the use of
"office-wide", "department-wide", and "building-wide" resources by the
same user without the client software or the user being aware of the
distinction.
Some applications of Galatea have included the recording of computer
generated animations onto write-once video discs (CALTECH CCSF), image
archive retrieval (Image Concepts, MIT VLW), educational applications
(MIT Project Athena) and off-line video editing prototypes (MIT
Interactive Cinema).
For more information on Galatea and its encompassing project, see the
paper "Light Table: Interface to Visual Information Systems" in the
MIT Press book "The Electronic Design Studio", published in 1990.
The Galatea Network Video Device Control System is not a product of or
in any way associated with Sun Microsystems, Inc. It is a project that I
am continuing to expand from my previous work at the M.I.T. Media Lab.
