FR2634921A1 - Display on a giant screen - Google Patents

Abstract

The giant display of static images is produced by the production of an array of juxtaposed video monitors, each connected to the output video of the video card of a microcomputer or computer or data communications terminal. The assembly is driven by a master computer which provides the synchronisation of the displays, the management of the overlays by the control of a dispatcher switching a video source to one or more screens, and the transfer of data by a telecommunications link.

Description

The present application relates to a core allowing the
dissemination of oiled tunages on a patrice of
monitors forming a mage of equal size to the
matrix and the animation and modification process
the content of display sequences.

Video display on a giant screen1 as well as it is known, is only possible by the ease of
very important and therefore very expensive means.

The poster 'big forint by multiple means is not
not possible in an illuminated environment, due to the lack of sunshine.

An intermediary solution allows to realize
viewing large video still shots drilled associated
i display cycle animations and i
insertions of aniseed wine on part of the nostril
The display wall is produced by a patrice from
video monitors, each associated with a microcomputer
or a computer terminal or a software task
run by a microcomputer with a card
video specific to this task and associated with a
video source signal selector
Icocomputers or computer terminals or
slave microcomputer tasks are used
to display large fornat still images.

Each part of the giant image is stored on
microcomputer trap holder and is displayed at
the denande or transmitted to the computer terminal or
its software enulator.

A microcomputer or a task to be born controls the
display cycle by ordering the microcomputers
or slave tasks, the video source selectors,
and video devices such as video disc, cd
Ron or VCR.

The fixed great forages are prepared using
of a graphic palette or of a tool of composition.

The display cycle is prepared using a
specific software.

Figure 1 shows the phase of making a mage
large format.

An Image (1) is digitized by digitization or
digitization (2) then edited using the palette
graphic of a microcomputer (3) or a
composition. The resulting image is then cut out.
according to the drill of a Matrix of x images by y images
(4) Each image is enlarged to fit the screen
with a "zoom" function of the graphic palette then
stored under strong x times y computer files.

All the files constituting an image are
then transmitted by communication (6) or by
physical transport (7) to the image wall.

 Figure 2 shows the blackberry.

The itir consists of a matrix of x by y micro-
computers or tasks of a microcomputer (8)
associated with a Monitor (9) representing part of the
Wall. A microcomputer or a master task (10)
contra the microcomputers or slave tasks and
manages display synchronization and animation of
images. A distributor (11) allows the selection of
image sources videotex (13), videodisc (12), cd
roa (14) -or other and sending the source signal by
overlay on the selected monitor or monitors.

The dispatcher consists of a relay matrix
switching video signals from a source to a
destination. The switching selection is taken
charging by the pilot microcomputer <10) through
a specialized link. Each source can be
connected to some or all of the televisions
Several sources can be used
simultaneously if they don't have the same destination. he
is therefore possible # to send x times y images
different on the x times y monitors or send a
image simultaneously on part of the matrix.

There are many animations available.
some examples illustrate the demand without
you might as well limit it.

EXAMPLES
Ex. 1: an image is scanned, "cut out", folds
shipped to Tue. The pilot microcomputer will rhythm
displaying the image by successively asking
each of the 9 monitors, the display of the game
image assigned to him. The upper monitor
displays the new image first, then it's at
second turn half a second after and so
continued until the 9th.

Ex 2: An image is cut out taking care of
leave the part at the bottom right free of all
registration. The Pilot microcomputer will display
image then select the overlay of the source
videotex with the monitor at the bottom right as destination.

The pilot microcomputer will then execute its Punctuation of telematic server and will send the text i overlay on a minitel whose video signal is used as source of the distributor. From a distance, a participant connects and modifies the content of the text displayed thanks to his telematic terminal.

EX 3: An image is cut leaving the first band of the image free. The image is displayed on the mr and the pilot microcomputer selects the video recorder source on the three monitors of the first band. The VCR image is sent to the monitor trots and then stopped by the pilot microcomputer. Another sequence can be started.

Claims (3)

- CLAIMS - 1- Means allowing the static video display on a giant screen consisting of a Matrix of x times y Juxtaposed video monitors characterized in that each video monitor of the matrix is connected to or to the video outputs of the display card of a microcomputer, computer or telematics terminal, 2- Means according to claim no 1 characterized in that a master microcomputer which can be a microcomputer ensuring the display on the matrix ensures the control of the display on the others video monitors.  3- Dean allowing the transfer of  information to the Video Wall characterized by  that at least one microcomputer or terminal  IT or telematics is equipped with  minus a communication link.  4- Means allowing the video overlay in  the giant image characterized in that a  dsspatcheur controlled by a microcomputer  directs a video source to one or more  video monitor matrix screens.
