Ultricore BCS - a new Broadcast Control System controller that adds more scale, more power and more capabilities to the Ultrix suite, and includes advanced license support for advanced systems.
Deploying a small form factor and promising powerful switching capabilities, a Ross Ultrix router is at the core of the OB Van, taking care of video/audio routing, multiviewers and embedding/de-embedding.
"Our key priorities included multiviewers, audio processing and clean switching, so the Ultrix looked impressively specified, but we clearly needed something larger than the existing 1RU and 2RU versions of the product.

IBM, Unisys, Amdahl, Sun, DEC, and Hewlett-Packard all followed suit and created their own versions and names: HP-UX, A/UX, AIX, Ultrix, and so on.
(53) Suppose, for example, a consumer alleges that a software licensor represented on its website that its software "is compatible with the Ultrix operating system," when it is not.
The Ultrix hydraulic press (ultra low deflection under load) is said to deliver unprecedented low levels of deflection and provides finished dimensions of molded parts to help customers eliminate costly and time-consuming post-press machining operations, according to a two-page, four-color bulletin.
SIFT was implemented in C and has been compiled on several Unix platforms: DEC Ultrix 4.2, HPUX 8.07, and SunOS 4.1.

However, it is straightforward to apply UIP by hand to programs written in the applicative-order functional language Scheme.(15) An empirical evaluation for a few hand-transformed programs was conducted using MIT Scheme (with the "compiler" option set, so as to generate compiled code) running under Ultrix on a DECstation 5000/33 with 24MB of RAM.(16) The running time and speedups obtained over the standard implementation are shown in Table III.
