Stella Vista's Research
and Development team of engineers and programmers has kept the design
and development in Stella Vista at a break-neck pace. The company
has always been at the forefront of the technological improvement
in the industry and has been one of the first to introduce technical
features now considered standard.
Stella Vista displays advanced features include: Virtual
Resolution®, standard 10-bit colour, FaceUp compatibility,
brightness and uniformity control, etc.
While the quality of the displays is extremely important,
a system is good only as its weakest part. This is why Stella Vista
employs considerable energy to design and improve its control systems
and software. Advanced features list, including real-time operating
systems, fibre optic transmission systems, customised software,
and many more, keeps growing.
We are learning every day, and adding to the palette of
services we offer, as well as disciplines we cover - be it programming,
electronics, optoelectronics, information technology, system design, etc.
By applying our knowledge and experience, today we are able to design
and implement a complete information solution. In this, we can utilise
different visual communications technologies, produce the software sub-system
and integrate the parts into something that can easily be controlled,
maintained and improved.
Titan Range
Titan video displays generate up to 1 Billion colours, are
flexible in size, mobility, rapidity of installation, and are able
to provide an outstanding visual experience under all lighting conditions,
whether indoor or outdoor, in stadiums and venues of any size. Additional
features that increase the overall picture quality are the proprietary
Virtual Resolution technology and uniformity correction.
Virtual Resolution technology employs interlacing of parts
of an image at a very high speed into one image with a resolution
multiple times higher than the actual number of physical pixels
in a display. Essentially, this technique multiplies the number
of pixels, but adds only a fraction of a cost to a conventional
display. The resulting dot-pitch (distance from center of one pixel
to centers of adjacent pixels) is smaller, producing a higher resolution
display that can be viewed from a closer distance.
Virtual Resolution and uniformity correction
combine to provide a unique system offering incomparable versatility,
and supplying an extra dimension to almost any event. The modular
design concept enables the assembly of modules into screens of any
size and shape, providing a seamless picture. LED intensity levels
can be regulated to provide the optimum visual quality relative
to any ambient light conditions, from complete darkness to direct
sunlight.
On-line and off-line video, vivid information, text,
graphics and animation can be selected on demand, assisted by off-the-shelf
and Stella Vista Muse proprietary computer software.
Constellation
Although based on graphical dot-matrix indoor LED
displays, the Constellation® information systems have a variety
of applications, some of which are: in sports stadiums, financial
centres, airports, entertainment complexes, call centres, industrial
operations, etc. Providing both indoor and outdoor information solutions,
the displays can be single colour or multicoloured generating up
to 16.7 million colours with multiple lines of text, graphics or
animation and can be stand alone or networked with other smaller
displays. The Constellation® systems are not limited to LED
technology and integrate other display types, such as LCD/LED combination
displays used at Johannesburg International Airports Domestic
Terminal, or strictly LCD, plasma or back-projection screens, depending
on the application demands.
LB Series
LB Series is the newest addition to the Stella Vista
product family. These displays feature a flexible product design
and are used as a cost-effective solution in application requiring
text and graphics display mostly in outdoor environments. The LB
Series was used as the basic building block for all the scoreboards
Stella Vista built ahead of the ICC Cricket World Cup 2003.
Control Equipment
Stella Vista uses a great variety of control equipment
to run and manage its screens. The most advanced Display Controllers
used in Titan® displays use VxWorks real-time operating system,
guaranteeing great reliability and performance. Other types of PC-based,
as well as 32-bit microcontroller units are used in smaller screens.
To transport information to the displays, a variety
of connectivity options are available, ranging from satellite downloads,
fibre-optic connections, fast Ethernet, to RS-232 serial and dial-up
modem links.
Software
Stella Vista has a wide range of internally developed
software products to enable clients to use the displays to their
full potential. They are developed through interaction with customers,
paying close attention to the requirements of each application.
Some of the Stella Vista developed software packages
are:
Stellaware Mercury production software is a versatile
product that enables the information from different program sources
as well as advertising logos, static messaging, simple animation
and graphics to be displayed on a variety of screens.
Stellaware Muse video replay software enables commercial
and highlights playouts on Stella Vista video-capable displays.
Stellaware OnLine package is used for fast display
of text and graphics pages on LED displays, primarily used in places
of worship, but also suitable for opera houses and other applications.
Stellaware AutoFIDS flight information display software
is used at airports in Namibia and Mozambique to inform passengers
of the airplane arrivals and departures.
In addition to the Stellaware line of software products,
Stella Vista integrates reliable, user-friendly and cost-effective
commercial software programs, depending on the application, with
the aim of satisfying the clients needs totally.
Advanced Features
One of the most innovative characteristics of the Stella Vista product
design is the use of the unique faceUp building block concept
which bases different displays on the same cluster size specification,
thus allowing easy maintenance and make possible various display design
options, such as easy mixing of electronic and static modules. This
standardisation also guarantees the spare part availability well into
the future, facilitates upgrading of modules, and creates a market
for second hand components. The faceUp system was first introduced
by Stella Vista in displays and scoreboards used at the ICC Cricket
World Cup 2003.
The displays remote diagnostics
capabilities include continuous remote status monitoring and control
room message display (mirroring). An integrated system monitor software
package shows the messages as they are on the displays, along with
other operation and performance indicators.

display design issues - December 1999
The full-colour video LED display market is growing rapidly. The
demand outstrips supply by far. This can lead to customers being

the absence of any standards in the field and the constant technological
development can lead to bad products, bad service, and bad name

Background to technological advancements
- June 1999
The development of electronic displays started several decades ago
with the use of luminescent lamps or lightbulbs. This progressed
to the use of cathode ray tubes ("CRT"s), which are also currently
used in television sets. The most advanced elactronic displays today
use LEDs...
