Definitions
- the present invention relates to a multi-source audio-video transmitter with remote control feedback.
- 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.
- sources which may be a video recorder, a CD player or a satellite receiver, to a television set.
- 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.
- this receiver broadcasts, by means of a 433 MHz transmitter, the signals of the various remote controls.
- a 433 MHz receiver receives the remote control signals and sends them to the source devices via one or more infrared emitting diodes.
- - 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.
- connection cord (s) passing over the front face of the devices are unattractive and their length cannot be easily adapted.
- 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.
- 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.
- FIG. 1 schematically represents an installation comprising three source devices connected by radio to a television set
- FIG. 2 shows the rear face of the audio-video transmitter
- FIGS. 3 and 4 show on another scale the tip of the optical fiber seen respectively from above and from below
- FIG. 5 is a section along the arrows F2 of FIG. 4
- Figures 6 and 7 are vertical sections along the arrows F1 of Figure 2, showing two variants of connectors
- Figure 8 is a view along arrow 3 of Figure 7 showing the departure of the optical fibers at the rear of the connector
- FIGS. 9 and 10 represent the connector of FIG. 6 seen respectively from above and from the side
- FIG. 11 is a section through this connector, without optical fibers or infrared diode
- FIG. 12 is a top view of the connector separated into its two constituent elements
- FIG. 13 is a cross section along the arrows F4 of FIG. 12
- FIGS. 14 and 15 represent the connector of FIG. 7 seen respectively from above and from the side
- FIG. 16 is a view of the rear of the connector of FIG. 15
- FIG. 17 represents, seen from the side, a locking piece of optical fibers
- FIG. 18 shows the blocking piece of FIG. 17 being inserted into the connector
- FIG. 19 represents the clip for fixing the connector of FIG. 6.
- 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.
- 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.
- 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).
- 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.
- 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.
- 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).
- 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.
- the connector 7 ' will preferably be made in one piece ( Figures 7 and 14 to 18).
