Description

TRANSMETTEUR AUDIO-VIDEO A SOURCES MULTIPLES AVEC EMETTEUR POUR LE RETOUR DE SIGNAUX DE TELECOMMANDE MULTI-SOURCE AUDIO-VIDEO TRANSMITTER WITH TRANSMITTER FOR RETURN OF REMOTE CONTROL SIGNALS
La présente invention a pour objet un transmetteur audio-vidéo à sources multiples avec retour de télécommande.The present invention relates to a multi-source audio-video transmitter with remote control feedback.
Elle concerne le domaine industriel et commercial de la fabrication et de la diffusion d'accessoires pour les équipements audio-vidéo, et en particulier ceux destinés au grand public. Le transmetteur a pour objet la transmission par voie hertzienne de signaux vidéo et audio d'une ou plusieurs sources, qui peuvent être un magnétoscope, un lecteur de disques compacts ou un récepteur satellite, vers un poste récepteur de télévision.It relates to the industrial and commercial field of the manufacture and distribution of accessories for audio-video equipment, and in particular those intended for the general public. The object of the transmitter is the transmission over the air of video and audio signals from one or more sources, which may be a video recorder, a CD player or a satellite receiver, to a television set.
Ce genre de produit, déjà commercialisé par plusieurs fabricants, comporte généralement un émetteur 2,4 GHz transmettant les signaux vidéo et audio de la ou des sources, et un récepteur 2,4 GHz recevant à distance ces signaux et les envoyant au téléviseur. En retour, ce récepteur diffuse, au moyen d'un émetteur 433 MHz, les signaux des différentes télécommandes. Associé à l'émetteur 2,4 GHz, un récepteur 433 MHz reçoit les signaux de télécommande et les envoie aux appareils sources par l'intermédiaire d'une ou plusieurs diodes d'émission infrarouge.This kind of product, already marketed by several manufacturers, generally includes a 2.4 GHz transmitter transmitting video and audio signals from the source (s), and a 2.4 GHz receiver receiving these signals remotely and sending them to the television. In return, this receiver broadcasts, by means of a 433 MHz transmitter, the signals of the various remote controls. Associated with the 2.4 GHz transmitter, a 433 MHz receiver receives the remote control signals and sends them to the source devices via one or more infrared emitting diodes.
On connaît plusieurs techniques permettant de transmettre les signaux infrarouges :Several techniques are known for transmitting infrared signals:
- Diode d'émission incorporée dans le boîtier de l'émetteur 2,4 GHz ou intégrée dans un boîtier translucide fixé en face des appareils à piloter et raccordé par un cordon à l'émetteur 2,4 GHz. Cette technique permet de piloter plusieurs appareils avec un seul émetteur infrarouge, mais la transmission IR est médiocre, et les appareils à piloter ne reçoivent plus les signaux de commande lorsque l'émetteur ou le boîtier est placé de côté ou en retrait. - Diode infrarouge intégrée dans un petit boîtier translucide qui est collé sur la face avant de chaque appareil à piloter. Cette diode est reliée à l'émetteur 2,4 GHz par un cordon 2 fils. Si plusieurs appareils sont à piloter, plusieurs diodes peuvent être montées en série le long de ce cordon. La transmission infrarouge est excellente, mais le nombre d'appareils pouvant être pilotés est limité en pratique (Deux appareils seulement dans les produits commercialisés) et il est impossible de désolidariser deux appareils sans décrocher le boîtier sur la face avant. En outre le ou les cordons de raccordement passant sur la face avant des appareils sont peu esthétiques et leur longueur ne peut pas être adaptée facilement.- Transmitting diode incorporated in the 2.4 GHz transmitter box or integrated in a translucent box fixed opposite the devices to be controlled and connected by a cord to the 2.4 GHz transmitter. This technique makes it possible to control several devices with a single infrared emitter, but the IR transmission is poor, and the devices to be controlled no longer receive the control signals when the emitter or the box is placed aside or set back. - Infrared diode integrated in a small translucent box which is stuck on the front face of each device to control. This diode is connected to the 2.4 GHz transmitter by a 2-wire cord. If several devices are to be controlled, several diodes can be connected in series along this cord. The infrared transmission is excellent, but the number of devices that can be controlled is limited in practice (Two devices only in products sold) and it is impossible to separate two devices without unhooking the box on the front. In addition, the connection cord (s) passing over the front face of the devices are unattractive and their length cannot be easily adapted.
- Le Brevet N° FR 2 689 224 déposé par PHILIPS ÉLECTRONIQUE GRAND PUBLIC décrit un dispositif, destiné notamment à l'enregistrement sur un magnétoscope d'émissions par satellites ou par câbles, et comportant un boîtier connectable à la prise de transmission sous forme électrique des signaux de télécommande infrarouge du récepteur satellite, ledit boîtier contenant une diode électroluminescente infrarouge émettant de la lumière en direction de l'entrée d'une fibre optique gainée pourvue à sa seconde extrémité d'un embout en forme de cloche muni d'une surface adhésive qui est collée sur la façade du magnétoscope, en regard de son récepteur de télécommande infrarouge. Ce système ne permet pas de piloter plusieurs appareils à une distance importante, et la fibre optique est implantée dans l'embout d'extrémité perpendiculairement à la face du magnétoscope, ce qui s'avère peu pratique et peu esthétique.- Patent No. FR 2 689 224 filed by PHILIPS ELECTRONIQUE GRAND PUBLIC describes a device, intended in particular for recording satellite or cable emissions on a video recorder, and comprising a box connectable to the transmission socket in electrical form infrared remote control signals from the satellite receiver, said housing containing an infrared light emitting diode emitting light towards the entry of a sheathed optical fiber provided at its second end with a bell-shaped endpiece provided with a surface adhesive that is stuck on the front of the VCR, next to its infrared remote control receiver. This system does not allow several devices to be controlled from a significant distance, and the optical fiber is implanted in the end piece perpendicular to the face of the video recorder, which proves to be impractical and unattractive.
Le dispositif selon la présente invention a pour objectif de remédier à cet état de chose. Il permet en effet de réaliser un système capable de piloter à distance un nombre d'appareils pouvant être supérieur à huit, à partir de l'émetteur audio vidéo, grâce à des fibres optiques peu visibles, pouvant être facilement branchées ou débranchées, et dont la longueur peut être aisément ajustée par l'utilisateur, ces appareils étant pilotés au moyen d'une seule diode infrarouge avec une excellente transmission du signal de télécommande.The device according to the present invention aims to remedy this state of affairs. It makes it possible to produce a system capable of remotely controlling a number of devices which can be greater than eight, from the audio video transmitter, thanks to optical fibers which are not very visible, which can be easily connected or disconnected, and whose the length can be easily adjusted by the user, these devices being controlled by means single infrared diode with excellent remote control signal transmission.
Il est constitué d'un émetteur audio-vidéo intégrant un récepteur de signaux de télécommande et comportant des moyens pour transformer ces signaux en impulsions électriques alimentant une diode infrarouge d'émission montée dans un connecteur spécifique pouvant recevoir de une à plus de huit fibres optiques, ces fibres comportant à leur extrémité un petit embout translucide muni d'une pastille auto-adhésive permettant de le fixer en regard de la fenêtre de réception des signaux infrarouges de télécommande de l'appareil source à piloter, ledit embout comportant, face à l'extrémité de la fibre optique, une face inclinée à 45° renvoyant le faisceau infrarouge à 90°, de façon à ce que la fibre optique soit parallèle à la face avant dudit appareil source.It consists of an audio-video transmitter incorporating a remote control signal receiver and comprising means for transforming these signals into electrical pulses supplying an infrared emission diode mounted in a specific connector which can receive from one to more than eight optical fibers , these fibers comprising at their end a small translucent tip provided with a self-adhesive patch allowing it to be fixed opposite the window for receiving infrared remote control signals from the source device to be controlled, said tip comprising, facing the end of the optical fiber, a face inclined at 45 ° returning the infrared beam at 90 °, so that the optical fiber is parallel to the front face of said source device.

Le dispositif, figures 1 à 19, est constitué d'un émetteur audiovidéo 1 raccordé à plusieurs appareils sources 2 et un récepteurs 3 relié à un téléviseur 4.The device, FIGS. 1 to 19, consists of an audio video transmitter 1 connected to several source devices 2 and a receiver 3 connected to a television set 4.
Le récepteur 3 comporte un capteur 5 de signaux de télécommande et un émetteur transmettant ces signaux vers un récepteur intégré à l'émetteur audio-vidéo 1 qui comporte des moyens pour les transformer en impulsions électriques alimentant une diode infrarouge 6 d'émission montée dans un connecteur 7, 7' spécifique monté à l'arrière du boîtier de l'émetteur et permettant de fixer plus de huit fibres optiques 8 en face de la diode 6 d'émission.The receiver 3 comprises a remote control signal sensor 5 and a transmitter transmitting these signals to a receiver integrated into the audio-video transmitter 1 which comprises means for transforming them into electrical pulses supplying an infrared emission diode 6 mounted in a specific connector 7, 7 ′ mounted on the rear of the transmitter housing and making it possible to fix more than eight optical fibers 8 in front of the emission diode 6.
L'émetteur 1 possède quatre prises "péritel" 9 permettant de raccorder quatre appareils source 2. Il est donc nécessaire de pouvoir piloter au moins quatre appareils (les produits existants ont au mieux deux prises "péritel").The transmitter 1 has four "scart" sockets 9 making it possible to connect four source devices 2. It is therefore necessary to be able to control at least four devices (existing products have at best two "scart" sockets).
Les fibres optiques 8 ne sont pas reliées entre elles dans le connecteur 7, et peuvent être insérées ou retirées individuellement, ce qui permet de déconnecter chaque appareil séparément. A l'extrémité de chaque fibre optique opposée au connecteur est monté un petit embout 10 translucide destiné à être collé, grâce à une pastille auto-adhésive 11 , sur la face avant de l'appareil source 2 à piloter, en regard de la fenêtre de réception des signaux infrarouges de télécommande. Cet embout comporte, face à l'extrémité de la fibre 8, une face inclinée 12 à 45° de manière à constituer un prisme renvoyant le faisceau infrarouge à 90°. Cette disposition permet à la fibre optique de se trouver parallèle à la face avant de l'appareil source 2 et à l'embout 10 d'être de faible épaisseur. Les fibres optiques 8 sont de type non gainé, transparentes et de faible section (diamètre 1 mm), ce qui limite la dégradation esthétique. Elles ne comportent aucun embout du côté du connecteur 7, ce qui permet de les couper à la longueur désirée avec un simple cutter, et de désolidariser les appareils source 2 sans décoller l'embout translucide 10.The optical fibers 8 are not connected to each other in the connector 7, and can be inserted or removed individually, which makes it possible to disconnect each device separately. At the end of each optical fiber opposite the connector is mounted a small translucent tip 10 intended to be glued, by means of a self-adhesive patch 11, on the front face of the source device 2 to be controlled, opposite the window. for receiving infrared remote control signals. This tip comprises, facing the end of the fiber 8, an inclined face 12 at 45 ° so as to constitute a prism returning the infrared beam at 90 °. This arrangement allows the optical fiber to be parallel to the front face of the source device 2 and to the nozzle 10 to be thin. The optical fibers 8 are of the unsheathed type, transparent and of small section (diameter 1 mm), which limits aesthetic degradation. They have no end piece on the connector side 7, which makes it possible to cut them to the desired length with a simple cutter, and to separate the source devices 2 without taking off the translucent end piece 10.
Le connecteur 7 est un bloc en matière synthétique moulée constitué de deux éléments semi-cylindriques 13, 14 assemblés de façon connue par encliquetage d'ergots élastiques. Il s'insère dans une ouverture prévue à cet effet dans la face arrière 15 de l'émetteur 1 et est fixé dans un clip 16 solidaire du boîtier de celui-ci. La partie du connecteur 7 dirigée vers l'intérieur de ce boîtier comporte un logement creux 17 recevant la diode infrarouge 6 d'émission et communiquant avec une cavité conique 18 dans laquelle aboutissent les fibres optiques 8 après être passées par des canaux cintrés 19 assurant leur maintien par frottement et débouchant à l'extrémité externe du connecteur. La diode 6 est immobilisée dans le logement 17 au moyen de crochets flexibles 20 prolongeant l'extrémité interne du connecteur (Figures 6 et 9 à 13).The connector 7 is a block of molded synthetic material consisting of two semi-cylindrical elements 13, 14 assembled in a known manner by snap-fastening of lugs. It is inserted into an opening provided for this purpose in the rear face 15 of the transmitter 1 and is fixed in a clip 16 secured to the housing thereof. The part of the connector 7 directed towards the inside of this housing comprises a hollow housing 17 receiving the infrared emitting diode 6 and communicating with a conical cavity 18 in which the optical fibers 8 terminate after having passed through bent channels 19 ensuring their friction holding and opening at the outer end of the connector. The diode 6 is immobilized in the housing 17 by means of flexible hooks 20 extending the internal end of the connector (Figures 6 and 9 to 13).
Selon une variante d'exécution, les canaux cintrés 19 peuvent être remplacés par une cavité 21 unique sensiblement cylindrique, les fibres optiques 8 étant maintenues au moyen d'une pièce de blocage 22 amovible s'insérant dans ladite cavité. Cette pièce de blocage comportera avantageusement un levier de manipulation 23 coudé, et une surface inclinée 24 permettant, par déplacement axial dans la cavité, une adaptation à différents diamètres de fibres optiques et un contrôle du serrage, un ergot 25 coulissant dans une ouverture 26 du connecteur 7', empêchant la sortie accidentelle de la pièce de blocage.According to an alternative embodiment, the curved channels 19 can be replaced by a single substantially cylindrical cavity 21, the optical fibers 8 being held by means of a removable blocking piece 22 inserted in said cavity. This blocking piece will advantageously include a bent manipulation lever 23, and an inclined surface 24 allowing, by axial displacement in the cavity, an adaptation to different diameters of optical fibers and a control of the tightening, a lug 25 sliding in an opening 26 of the connector 7 ', preventing accidental release of the blocking part.
Dans cette version, le connecteur 7' sera de préférence réalisé en une seule pièce (figures 7 et 14 à 18).In this version, the connector 7 'will preferably be made in one piece (Figures 7 and 14 to 18).
On peut envisager de piloter un nombre quelconque d'appareils sources par le dispositif décrit en modifiant la conception du connecteur (7, 7").It is conceivable to control any number of source devices by the device described by modifying the design of the connector (7, 7 ").
Le positionnement des divers éléments constitutifs donne à l'objet de l'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus par des procédés similaires. The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by similar methods.
