Release Date 2.4.92.
Acorns at the Heart of Election Coverage
Acorn Archimedes computers will be playing a crucial role in Wales on election
night. Six of them will be at the heart of the graphics system being used by
BBC Wales to provide Sianel pedwar Cymru (S4C television) with its General
Election coverage. A cut-down version will also be used by BBC Northern
Ireland.
Although some television stations use conventional tools such as Quantel
Paintbox to generate animated charts, BBC Wales decided to look for a
quicker and more cost effective method of producing on screen graphics.
Cardiff-based Now Motion, headed by Carl Blundell, won the tender - having
provided a similar results service during the 1987 election for BBC Wales and
two years later for BBC Northern Ireland on the occasion of their local
elections.
Three Acorn A440s fitted with ARM3 processors, and each connected to a
Millipede Prisma 3 board, generate the graphics. One provides the headlines
(in the form of a strip at the bottom of the screen) whilst the other two
generate over 50 different full frame graphics such as shares of votes,
predictions, state of the parties and so on.
A fourth A440 captures data from a separate Microvax system in BBC Wales
which is fed with raw results from the central election unit in BBC London.
This is then used to give journalists in the studio a constant feed of
background information and results. This fourth Archimedes provides buffers
large enough to hold all 651 results for all the other machines.
An A310 computer provides the operators and producers with a scrolling data
feed of the last forty declared results, and this is also fed to BBC Radio
Wales and Radio Cymru for their election coverage. Finally, another A310 is
used as a slave to the main full-frame graphics computer and provides
information for the presenters on what graphics are about to come up.
The computers can also pick up 'on-air' information from the studio to
identify results that have already been transmitted and alllow the presenter
to move through graphic sequences under his own control.
All of the software has been written by Carl Blundell and picture elements
used within the graphics sequences were created using Now Motions's own
design of paint package. The graphics programs all run within the Acorn
computers' fully multitasking desktop environment allowing them to work
in conjunction with other software such as databases and text editors.
A special feature of the package is that all the scripts and databases are
bilingual allowing instant switching between English and Welsh. And as the
results come in the computers will be able to calculate their own predictions
of the final outcome within less than two seconds.
Commenting on the contract, Carl Blundell said that because S4C is a
national television station it has to enter into competition with the
English language networks to produce results and analysis as quickly and
accurately as possible. "The graphics must look good to stand up to those
produced by the competition, despite a huge difference in the available
budgets. The only way to achieve that goal is by the use of customised
software.
"Conventional TV graphics tools such as Quantel cannot produce animated bar
charts without considerable manual effort. However, Acorn computers with
their multitasking desktop environment and their fast ARM3 processors are
more than adequate to provide a powerful graphics environment which will
be tested to the limit by the election coverage. "
Notes to Editors:
BBC Wales supplies S4C - the Welsh channel four - with all its news output,
and for the election night it will provide an all night results programme
covering the 651 constituencies of the UK.
Carl Blundell worked for a number of years in the BBC as a studio cameraman
and later in the special effects department working on title sequences,
programme graphics and video gameshows. In 1989 he left the BBC to join
Stylus Television in Cardiff as facility manager, designing the expansion of
this graphics based facilities house.
In January 1991 he set up Now Motion and, apart from developing the new
techniques at the core of the 1992 election system, he has also devised
and created three live video games especially for television, and is
already working on the development of what will be his 11th TV show.
