Abstract

The local information network can be used as a transmission medium, and twisted pair protocol used to transmit the digital information to the subscriber.

Description

La présente invention concerne un dispositif permettant d'utiliser un câble en paires torsadées véhiculant des données informatiques sur un réseau de type Ethernet, Fast Ethernet ou Token Ring pour diffuser simultanément plusieurs canaux de Télévision vers les ordinateurs connectés au réseau. The present invention relates to a device making it possible to use a cable in twisted pairs carrying computer data over a network of Ethernet, Fast Ethernet or Token Ring type to simultaneously broadcast several television channels to the computers connected to the network.

L'invention permet donc d'utiliser le câblage du réseau informatique de type
Ethernet, Fast Ethernet ou Token Ring pour diffuser des canaux de TV aux utilisateurs connectés, et ceci sans nécessiter l'installation de câblage supplémentaire. II en résulte une économie de temps et d'argent pour l'utilisateur.The invention therefore makes it possible to use the cabling of the computer network of the type
Ethernet, Fast Ethernet or Token Ring to broadcast TV channels to connected users, without requiring the installation of additional cabling. This results in a saving of time and money for the user.

Généralement la distribution d'information de type Vidéo ou Télévisuelle fait l'objet d'une installation de câblage spécifique de type:
. Câble coaxial TV avec un ensemble de répartiteurs, amplificateurs,
prises TV murales ; ce type d'installation permettant la distribution de
plusieurs canaux UHF ou VHF.Generally the distribution of Video or Television type information is subject to a specific type of wiring installation:
. TV coaxial cable with a set of splitters, amplifiers,
wall mounted TV sockets; this type of installation allowing the distribution of
multiple UHF or VHF channels.

Câble Paires Torsadées en liaison point à point mais ne véhiculant
qu'un seul canal en Bande de Base . Twisted Pairs Cable in point to point link but not carrying
only one Baseband channel.

Le dispositif selon l'invention comporte un premier système appelé boîtier Coupleur qui se compose de connexions en entrée et en sortie du réseau informatique, ainsi qu'une entrée et une sortie devant recevoir une connexion
RF.The device according to the invention comprises a first system called a Coupler box which is made up of connections to the computer network's input and output, as well as an input and an output that must receive a connection.
RF.

Les dessins annexés illustrent l'invention
La figure 1 présente un synoptique de raccordement..The accompanying drawings illustrate the invention
Figure 1 shows a connection diagram.

La figure 2 présente le boitier coupleur et le boîtier splitter. Figure 2 shows the coupler box and the splitter box.

La figure 3 présente le plan de connexion spécifique de l'invention. Figure 3 shows the specific connection plan of the invention.

En référence à la figure 1, le dispositif Coupleur se connecte sur les sorties du ou des concentrateurs de réseaux Ethernet ou Token Ring, il va adjoindre un signal modulé reçu du port RF (véhiculant les canaux de Télévision) à ses mêmes sorties, à travers les paires du câble non utilisées par le réseau, et renvoyer le tout à destination des différents postes clients
Au niveau de ces postes clients, un autre système appelé boîtier Splitter > , va séparer les signaux de type réseau des signaux de type vidéo, afin de les router correctement sur leurs points d'arrivée respectifs.(Carte réseau Ethernet, Fast
Ethernet ou Token Ring et Poste TV, Carte d'incrustation vidéo TV sur PC ou boîtier d'incrustation vidéo).Referring to Figure 1, the Coupler device connects to the outputs of the Ethernet network concentrator (s) or Token Ring, it will add a modulated signal received from the RF port (carrying the television channels) to its same outputs, through the cable pairs not used by the network, and send everything back to the various client stations
At these client workstations, another system called Splitter box>, will separate network type signals from video type signals, in order to route them correctly to their respective end points. (Ethernet network card, Fast
Ethernet or Token Ring and TV set, TV video overlay card on PC or video overlay box).

L'invention est basée sur l'utilisation à l'intérieur d'un câble de catégorie 5, de type STP, FTP ou 13TOP, d'une paire de fils qui ne sont pas utilisés par les réseaux pour véhiculer plusieurs porteuses vidéos. The invention is based on the use inside a category 5 cable, of STP, FTP or 13TOP type, of a pair of wires which are not used by the networks to transport several video carriers.

En référence à la figure 3 les types de réseau 10 Base T et 100 Base T utilisent les fils 1,2,3,6, les réseaux Token Ring utilisent les fils 3,4,5,6. La présente invention utilise la paire de fils 7 et 8 pour véhiculer le signal modulé.With reference to FIG. 3, the 10 Base T and 100 Base T network types use the wires 1,2,3,6, the Token Ring networks use the wires 3,4,5,6. The present invention uses the pair of wires 7 and 8 to convey the modulated signal.

Afin de ne pas créer de perturbation au niveau du réseau informatique, le signal modulé utilise les bandes VHF Bande 1 et 3 qui permettent de ne pas rencontrer de fréquences dans la même plage que le réseau, et d'avoir une perte minimum due à la longueur du câble.In order not to create disturbance in the computer network, the modulated signal uses the VHF bands Band 1 and 3 which make it possible not to encounter frequencies in the same range as the network, and to have a minimum loss due to the cable length.

En référence à la figure 2 et à titre d'exemple non limitatif, le boîtier Coupleur est composé de 12 entrées de type fiche RJ45 et de 12 sorties de type fiche RJ45, il comporte également une entrée et une sortie BNC permettant de recevoir le signal MABLR et de le ressortir vers un autre
Coupleur pour les montages en cascade . With reference to FIG. 2 and by way of nonlimiting example, the Coupler box is composed of 12 inputs of the RJ45 plug type and of 12 outputs of the RJ45 plug type, it also includes a BNC input and output allowing the signal to be received. MABLR and bring it out to another
Coupler for cascade mounting.

En référence à la figure 2 et à titre d'exemple non limitatif, le boîtier Splitter est composé d une entrée de type fiche RJ45 provenant du dispositif Coupleur d' une sortie de type BNC à relier au tuner du dispositif d'affichage des images et d'une sortie de type fiche RJ45 à relier à la carte réseau de l'ordinateur.With reference to FIG. 2 and by way of nonlimiting example, the Splitter box is composed of an input of the RJ45 plug type coming from the device Coupler of an output of BNC type to be connected to the tuner of the image display device and an output of RJ45 plug type to connect to the network card of the computer.

Le boîtier Coupleur et le boîtier Splitter sont tous deux équipés d'une lumière verte indiquant que la connexion est bonne entre les deux dispositifs. Both the Coupler box and the Splitter box have a green light indicating that the connection between the two devices is good.
