Description

TECHNICAL PROBLEM
A group of individuals, varying from 100 to 400 people, gathered simultaneously in the same place, wanting
. either carry out diffusion operations,
mixing, processing of computer signals (images, sounds and data),
. either communicate remotely with an individual or a group
made up of an equal or greater number of individuals, by issuing and / or
receiving said signals,
. either alternate the states of "closed circuit" and "open circuit"
thus described,
must accept the following three constraints
. in the case of "closed circuit" operation: the non-integration of
technologies. Their simultaneous use is technically difficult because not
planned from the outset on the premises intended to accommodate the men group
tionné.

. in the case of "open circuit" operation, this same non-integration of technologies, to which is added the low level of service
tion: weak interactivity (possibility of dialogue), inability to
"process" (realize and modify directly) the signals, the limits of
provisional solutions, the sophistication of those which could be envisaged coming up against problems of reliability and costs (inexistence of economies of scale and effects of experience).

PREVIOUS ART SOLUTIONS
Taking into account, on the one hand, the incompatibility between the level of services
can be offered and the number of "interlocutors" (sender and receiver of signals) benefiting from these services, incompatibility being
schematize in the following way
Methods of broadcasting and television broadcasting
Centralized Decental i sé
Service level High Limited
Number of interlocutors Restricted High and, on the other hand, of the limits of the provisional solutions described above, it can be said that, in the current state of the application of techniques, there is no satisfactory solutions.

DESCRIPTION
The object of the present invention, the brand name of which is "ARGOCOM
SYSTEM "is to define a new combination of means, creating a broadcasting (" closed circuit ") and television broadcasting (" open circuit ") system permanently applicable to a maximum of 7 places, existing or to be created, without constraints of establishment geographic, with a unit capacity of 100 or more
This system consists of the engineering shown on Plate 1/1 attached to this document.

- Technical means required. Technical characteristics of these means
Each of the 7 locations (1) and (7) is equipped with - a teleprojection booth (VIDEAC Talaria type video projector
PJ 5055 xB / EM, MLV 5055 Sc / EM or equivalent and a large screen (30 - and / or an adequate number of video monitors, - TV cameras and their remote control, - a light assembly, allowing the isolated lighting of 6 interlocutors, - of an HF micro transmitter assembly at the rate of one for 6 interlocutors ,.

- two parables: one transmitting, the other receiving.

An "audiovisual" control center (2) and a computer center (3) are integrated in the first equipped location.

Control equipment (2): main equipment and images and sounds annex, organ games, real-time microcomputer.

Computer center equipment (3): COMPAQ 80 386 or equivalent microcomputers, graphics software, CAD software, computer - video interface, expert system.

Interactive links are provided on the one hand between the computer center (3) and databases (4) by TRANSPAC / ISDN links (C) or equivalent, on the other hand between the control room (2) and the SERTE (10 ) the closest to the first place equipped (1) either by radio-relay systems (a) and TRANSPAC / ISDN links (c) or equivalent or by optical fiber (d) or equivalent.

The means of television broadcasting usable by the interlocutors (transmitters and receivers of signals) present in one of the 7 equipped places intended for on the one hand the interlocutors present in 1 to 6 of the other places, on the other hand interlocutors present in all other place with adequate equipment, are as follows
. bilateral videotransmission: technique allowing the simultaneous and direct emission and reception of images and sounds.

The transmitter can be either one or more temporary points (5), or one or more fixed points (6) and (7).

The connection being ensured by radio-relay systems (a) or equivalent, the operation is reciprocal.

 .interactive telematics: technique enabling the simultaneous and direct transmission and reception of computer data.

 The link is identical to that provided for the "image-sounds" function, but is provided by tRANSPAC / ISDN (c) 5 equivalent.- telephone network. Multipoint broadcasting: technique allowing the broadcasting of the "governed output" (mixing, processing of images, sounds and data) to all points equipped with receiving satellite dishes (8) and (9).

This broadcast is provided by Telecom 1-3 satellite “repeater” (channel) or equivalent.

Interactivity is achieved by "voice link" (telephone) and / or Minitel and / or ISDN (e) or equivalent.

Two types of links are therefore available, a first one (A): radio-relay systems (a) or equivalent and TRANSPAC / ISDN (c) or equivalent. Allowing bilateral video transmission and interactive telematics,. Can be applied to one or, simultaneously, several provisional (5) or fixed (6) and (7) points.

. one second (B): satellite repeater (b) or equivalent and TV network
phonic (e) or equivalent. allowing multi-point broadcasting and interactivity. can replace a link (A) if necessary.

For confidentiality reasons, transmission and reception (radio beam (a), satellite repeater (b)) are encrypted.

- Operating mode
The places, existing or to be created, must be in the form of a hemicycle in tiers. The latter is focused on a large screen (30 m2) on which computer signals are "video-projected" and / or equipped with an adequate number of video monitors on which said signals are broadcast.

Two complementary and combinable uses are therefore provided: one in "closed circuit", the other in "open circuit".

- use in "closed circuit"
Computer signals are formed. of images, either directly from the equipped place or places: intervening on the podium, each participant (grouped into "trays" of 6 people on average) is recorded,. of computer data: from the simplest (tables, graphs, histograms) to the most complex (CAD). the "mixing" of these images and data ("windows", inlays, medallions). live "processing" of these images and data (all images and data can be "processed", that is to say produced and modified on request).

- use in "open circuit"
Depending on demand, images and data - mixed, processed - can be sent either to temporary points (5) (OB vans and mobile dishes) or to fixed points: Teleports and Intelligent Buildings (6), places 2 to 7 (7), Networks (8) and (9).

It is also possible to receive images and data from these temporary or fixed points.

Are therefore connectable
Teleports and Smart Buildings (b)
Teleports are defined as Business Centers bringing together companies with a tertiary vocation, in a privileged location ("smart park").

In order to benefit from economies of scale on investments, operating and maintenance costs, Companies use MTTS (Multi Tenants Telecommunication Services), or IT and communication services, on a timeshare basis.

In addition to these services, there is the ability to receive and transmit signals (images, sounds and data).

Are operational: 20 Teleports in the USA, 5 in Europe: Amsterdam,
Grenoble-Moirans, London, Metz 2000, Sophia-Antipolis.

On the horizon 90/95 are planned: Annemasse-Archan, Lyon-St Didier, Nan-.

tes, Poitiers, Roubaix in France, Cologne and Hamburg in the FRG, Osaka,
Tokyo, Yokohama in Japan.

Due to the technological capacities indicated, the Companies located on the Teleports are immediate potential users of the equipped premises.

Places 2 to 7 (7)
After equipping the first place (1), that of places I to 7 (7), existing or future is possible and can be phased.

Networks (8) and (9)
Three networks exist
The France-Telecom network or similar (8)
This network aims to make Local Communities receptive of programs.

To do this, the municipal cinemas, the Maisons de la Culture and the Polyvalent Centers are equipped with satellite dishes and video projectors.

The programs currently planned are in the domain of the general public and institutional.

It is clear that the addition of "relaying" of professional services is a very promising possibility.

The Congrespace network or similar (9) voluntary chain of 10 Congress Centers at national level, including the
CIP.

 The Videoseace network or similar (9) made up of 26 hotel complexes.

BENEFITS AND IMPROVEMENTS. make possible for all places with a reception capacity of more than 100 people, the exploitation both in "closed circuit" and in "open circuit" of the most advanced technologies of diffusion, mixing, processing, emission, reception of images, sounds and data with a high level of service, total integration, guaranteed reliability, cost savings (economy of scale, experience effect) and efficiency. These places thus reinforce their "identity" and define themselves also as high value added poles of a professional telecommunication network,. allow "interlocutors" (transmitters and receivers of signals) to have access to these technologies with very great simplicity of use and low learning: requests for intervention by simple press of a push button fitted to each seat, modification of signals " by voice "(each interlocutor makes his request by HF microphone. The latter is transmitted to the control room (2) and / or to the computer center (3) with possible call to the databases (4). The result is video-projected or broadcast on video monitors in 5 seconds maximum),. offer operating flexibility to cover a wide range of services and predict their development, avoiding "freezing" investments on meeting narrow and time-limited demands.
