Description

1 = 2538980

  The present invention relates generally to television receivers and relates more

  particularly a television receiver intended to receive

  see an input signal from either an antenna or an auxiliary device. With the growing popularity of personal computers and video games, it has become desirable to connect the personal computer or video game to a

  television receiver running so that the cathos-

  the receiver can serve as a display device for the video game or the personal computer In this way E

  the extra expense and space expected due to a Catholic

  separate cope for personal computer or video game

  In addition, the existence of antennas has

  The satellite dish allows the direct reception of satellite telecommunications broadcasts in individual dwellings, provided that the reflector antenna can

  be properly connected to the tele-

  vision. A prior art television receiver has a single input terminal for connection to an antenna. The antenna receives a plurality of high frequency broadcast channel signals corresponding to different transmitters or television channels and one of broadcast signals is selected to be visualized on the cathoscope by the selective operation of the push buttons

  or a dial mounted on the receiver with easy access.

  A tuning stage in the television receiver responds to the operation of a push button, for example to a characteristic tuning voltage produced by the operation of the

  button, tuning the receiver to a particular channel.

  For example, to use the television receiver as a video game display device, the video game output cable must be connected to the television receiver via its input terminal and one of the push buttons of the video receiver. channel selection must be manipulated to tune the receiver on the high frequency characteristic of the video game output In order to avoid the need to physically disconnect

2 2538980

  the antenna and to connect the video game output cable to the television receiver whenever it is necessary to switch from one to the other, an external or auxiliary switching device has been proposed as an accessory interposed between the input terminal of the receiver

  and the antenna and the video game or the personal computer.

  In one position of the switching device, the antenna is connected to the input terminal of the receiver and one of the channel selection push buttons on the receiver can be operated to select the broadcast television signal on the respective channel for present it on the cathoscope In the other position of the auxiliary switching device established by the operation of a push button of

  status selection or by operating a button on the

  switching device, the output cable of the video game or personal calculation is connected to the input of the receiver and another selection push button for example that associated with a channel not received at the position of the television receiver, is maneuver for tune the receiver on

  the output frequency of the video game or calculator.

  However, the use of this prior device has some disadvantages This device uses switches or push buttons on two

  separate devices, ie the selector push-button

  channel on the television sector and the push button or the status selection button on the switching device Switching from a particular television station to the video game requires the operation of the selection push button on the control device. terminal or accessory switching, and also the operation of one of the channel selection pushbuttons corresponding to the agreement on the frequency of the output of the video game In a similar way, to go from the video game to the reception

  a desired channel or transmitter on the tele-

  vision, first requires that the state selection push button on the switching device is manipulated to connect the antenna to the input of the receiver and that one of the channel selection pushbuttons is operated to select the desired channel So,

3 2538980

  two maneuvers are needed to move from one to-

  the other visualizations of the video game and the channels of

wanted television.

  In addition, since the prior apparatus requires two independent devices or boxes, that is,

  to say the television receiver and the device-of

  or combination, the resulting combination may not be aesthetically pleasing and take up more space than the user wishes for this purpose. In addition, it may be necessary in some cases to install the switching device some distance from the receiver. television, which results in a disadvantage for the user who has to move in one direction and the other between the two,

which creates a disadvantage.

  The same disadvantages apply to the passage from a particular television program to the observation of a signal from a directional antenna used to eliminate ghost images or from a parabolic reflector antenna to receive a telecommunication broadcast

by satellite.

  An object of the invention is therefore to propose a television receiver that overcomes the disadvantages

  mentioned above of the prior art.

  More particularly, an object of the invention is to provide a television receiver that can selectively receive an input signal from a conventional antenna or an auxiliary device, such as a game.

  Another object of the invention is to provide a television receiver comprising a plurality of inputs adapted to be connected to an antenna and an auxiliary device, such as a video game or a computer and a selector mounted on the cabinet of the television receiver.

  itself to select one of the input terminals.

  Another object of the invention is to propose

4 2538980

  a television receiver with a plurality of input terminals as aforesaid, and wherein the input terminal adapted to be connected to an auxiliary device is

  located on the front panel of the cabinet of the receiver.

  Another object of the invention is to propose a television receiver of the aforementioned type, in which the passage between the display of a picture of

  television broadcast on a selected channel and the visualization

  the output of a video game or a calculator can be carried out in a simple manner, for example by

  operating a single push button or the like.

  Yet another object of the invention is to provide a unified television receiver and an input terminal selector which is attractive and easy to mount and

to maneuver.

  According to one aspect, the invention thus relates to a television receiver comprising at least two input terminals for receiving respective input signals, an antenna connected to a first of these terminals for applying to it an antenna input signal. , a second of these

  input terminals being located on a front panel of the

  input signal applied to the selected terminal.

  Other features and benefits of

  invention will be better understood on reading the description of

  embodiment of the invention, and FIG. 7 is a diagram of a main part

  of the television receiver of Figure 6.

  Before going on to a detailed description of

  In the invention, reference should be made to FIG. 1 which shows a prior art arrangement for selectively applying a plurality of inputs to a television receiver 1 having a single input terminal 2. switching device 3 is provided separately, or as an accessory external to the television receiver 1 and it has an output terminal 3a connected to the television receiver 1 by a cable 4 connected to the input terminal 2 The switching device of antenna 3 has two input terminals and 6 A conventional antenna 7 for receiving signals broadcast on different channels or transmitters is connected to the switching device 3 by an input terminal 5 while an input auxiliary device, as a video game 8 is connected to an input terminal 6

  of the switching device 3 by an output cable 9.

  A state selector button (not shown) on the dis-

  positive switching 3 can be manipulated to select

  the input terminal 5 or the output terminal 6, i.e. an antenna input signal or a game input signal respectively, to be connected via the output 3a to the receiver input 2 The signal received at the

6 2538980

  input terminal 2 is transmitted to the tuning circuit 10 by any conventional means. The television receiver 1 also comprises a catheter 11 and a number of channel selection buttons (not shown) corresponding to the different transmitters or television channels. Thus, the pushbuttons are selectively operated to tune the receiver to the high frequencies with which the television signals are broadcast on the respective channels. In addition, one of the push buttons, preferably a button corresponding to a channel which can not to be received at the location of the television receiver, may be operated to tune the receiver to the high frequency at the output of the video game 8 or other auxiliary input device. In the operation of this provision

  receiver 1 can be used as a receiver.

  When the state selector push button is in the selection position of the input terminal 5 of the switching device 3 In this case, an antenna or broadcast input signal received by the receiver antenna 7 can be visualized on the catheter 11 thanks to the operation of the pushbutton for selecting

  appropriate channel that grants the receiver accordingly.

  Alternatively, the state selector button may be moved to select the input terminal 6 which receives the video game output signal 8 In this case, that of the channel selection push buttons which is operated to tune the receiver 1 on the high frequency of the output

  video game 8 must also be manipulated in a similar way.

  the passage of the display of the auxiliary signal from the video game 8 to the viewing of a television signal broadcast by a selected channel or transmitter first requires the operation of the state selection button on the switching device 3 to reapply the antenna signal to the input terminal 2, then another operation of one of the push buttons to select the desired channel If the television receiver 1 and the switching device 3 are remote the one of the other the operation of the push buttons on the receiver and the switching device can be inconvenient Moreover, the switching device 3 as a separate accessory element outside the television receiver can lead to a messy or unsightly appearance and At an undesirable increase in the space required In general, to avoid this unsightly appearance, the switching device 3 is often said. posed behind receiver 1 but this increases the difficulty of source switching

from one input signal to another.

  Figure 2, on which the elements correspond to

  of those described above with respect to the prior arrangement of FIG. 1 are identified by the same numerical references, shows that a television receiver 1A according to one embodiment of the invention comprises a cathoscope 11 for displaying the 'a selected

  input signals applied to input terminals 2a and 2b.

  More particularly, the input terminal 2 is represented at the rear of the receiver 1 A and is intended to be connected to an antenna 7 which receives broadcast signals, and an input terminal 2b adapted to be connected by a

  cable 9 to a video game to receive the output signal.

  According to the invention, the input terminal 2b is disposed on the front panel 12 of the receiver 1A so that the video game 8 or other auxiliary input device can be

  easily connected or disconnected.

  On the front of the television receiver 1A is mounted a set 13 of channel selector which comprises a plurality of VHF channel select buttons 13a-131 and a 13m UHF channel select button which are selectively operated to tune the receiver on a respective channel The front panel 12 also carries

an on / off switch 14.

  In addition, on the front panel 12 of the receiver 1 A there is an input terminal selector 15, shown in the form of a push button, which can be operated to select the input terminal 2b by the maneuver.

8 2538980

  of this button in the same way that a particular channel is selected, so that the receiver is tuned to the characteristic frequency corresponding to the signal from the auxiliary device. It is understood that more than two input terminals may be provided on a receiver according to the invention, and in a second embodiment which will be described later, selectors are provided to select any one

  additional input terminals.

  The selector 15 is preferably located at the front of the television receiver 1 A, adjacent to or adjacent to the channel selector assembly 13 to form a

  unified selection panel, as shown in Figure 3.

  The selection panel further comprises a volume control 17 The channel selection pushbuttons 13a to 13m and the selector 15 control the tuning of the television receiver 1A to view a television broadcast signal on a channel particular, or the game's release

video 8.

  The input terminals 2a and 2b are both connected to a switching circuit 16 which is the means by which a selected signal of one of the input terminals is transmitted to a conventional tuning stage 10, and which also produces an appropriate control voltage Vc for the tuning circuit 10 in order to tune the receiver so that it displays the selected signal. More particularly, the tuning stage 10 (FIG. 2) may comprise, for example, a diode variable capacitance (not shown) i.e. an analog voltage controlled variable reactance component, such as a variable capacitance diode, used as the tuning element and the control voltage Vc is

  obtained by a potentiometric network.

  In the embodiment of the invention shown in FIG. 4, this potentiometric grating is provided in the channel selection assembly comprising tuning voltage sections, whose sections 18a and 18m which correspond to the buttons of FIG. channel selection 13 a and 13 m respectively and another chord voltage section

9 2538980

  18 T associated with the selector 15 are shown Of course, a tuning voltage section is provided for

  each channel represented in the set 13.

  The tuning voltage sections 18 to 18 m, 18 T are shown with the same embodiment and consist respectively of selection switches 19 to 19 m, 19 T and 20 to 20 m, 20 T, potentiometers 21 to 21 m, 21 T respectively and visual indicators 22 to 22 m, 22 T, for example in the form of neon lamps or light-emitting diodes The tuning voltage sections 18 to 18 m, 18 T further comprise three-pole switches 23 to 23 m and 23 T respectively to be connected to lines L, H and U corresponding to the frequency bands of the low frequency channels 1-3, high frequency channels

  4-13 and ultra-high frequency channels respectively.

  These lines, L, H and U are connected to the tuning circuit by a conventional circuit (not shown) and they are used in the conventional manner with the control voltage Vc which allows the tuning of the receiver over a wide range.

frequency band.

  Since the tuning sections 18 to 18 m and 18 T (and the other sections not shown corresponding to the other channels) are similar, only the interconnections and operations of the switches 19a, 20a, of the potentiometer 21a, the visual indicator 22a and the permutation switch 23a of section 18a will be described in detail and it is understood that the interconnections and operations of the corresponding elements of the other sections

are usually the same.

  In the tuning voltage section 18a, working contact switches 19a, 20a are made or paired to open and close together. The resistor element 24a of the potentiometer 21a is connected between a terminal 25 connected to a power source + VT

  (which can be 33 V) and a terminal 26 connected to ground.

  The visual indicator 22a is connected in series with the switch 20a between a terminal 27 connected to a suitable source of supply voltage + Vn and a terminal

2538980

  connected to line U, H or L depending on the selected channel.

  At the simultaneous closing of the switches 19a and 20a, a predetermined tuning voltage 20c is produced on the fader of the potentiometer 21a and is transmitted by the switch 19a closed to be applied as the control voltage to the circuit. 10 (not shown in Figure 4) by the terminal 28, so that the tuning circuit 10 grants the television receiver

  1A on a corresponding high frequency input signal.

  Closing the switch 20a supplies the visual indicator 22a to indicate that the television receiver is

  granted on the channel to which Section 18 a corresponds.

  Of course, the sliders of the potentiometers 21a, 21m, 21t are positioned so that different control voltages are applied to the tuning circuits 10 to the selective closing of the switches of the corresponding tuning sections. For example, it is desirable to that the sliders of the potentiometers 21a, 21m are positioned so that the control voltages applied to the tuning circuit 10 at the closing of the respective switches cause the tuner 1A to agree on the frequencies at which the television signals are broadcast in the different channels Therefore, the

  switches 19 to 19 m and 20 to 20 m constitute the

  channel selectors, in which the closing of a pair of switches causes the receiver 1A to agree on the corresponding broadcast channel These channel select switches may be operated from their open position to their closed position and their closed position in their open position to select the respective channels in response to the selective operation of the buttons

pushers 13 to 13 m.

  Moreover, the switches 19 T and 20 T, of the same structure as that described above, have the function of tuning the receiver 1 A to display the auxiliary input signal. It should be noted that the slider of the potentiometer 21 T is positioned so that when the switches 19 T and 20 T are closed, the tuning or control voltage applied by the potentiometer 21 T to the tuning circuit 10 causes the tuning of the receiver 1 A on the high

  output frequency of the video game 8.

  The input signals of the terminals 2a and 2b are selectively transmitted to the tuning circuit 10 by the permutation switches 29 and 30 which form part of the switching circuit 16 When the input terminal 2 has been selected by the maneuver of one of the channel selection push buttons 14a, 13m, the permutation switch 30 is open and the permutation switch 29 is closed in addition to the respective switches in the tuning section 18a to 18m associated with the selected channel The input signal received by the antenna is then transmitted by the switch 29 closed to a terminal 31 and the tuning circuit 10, as well as the control voltage Vc appropriate by the terminal 28 Alternatively, when the selector 15 is

  maneuvered so that the input terminal 2b is selected

  In order to transmit the video game signal 8, the permutation switch 29 is open and the permutation switch 30 is closed, with the switches of the tuning section 18 T and the auxiliary input signal as well as the control voltage. appropriate Vc are transmitted to the

  tuning circuit 10 through terminals 31 and 28 respectively.

  The switching circuit 16 also comprises capacitors

  32 and 33, which serve as isolation from the

mass of the receiver chassis.

  The channel selection push buttons 13 to 13 m and the selector 15 are made so that only one of them can be operated at a given moment and that the operation of one automatically causes the rest of the others to be idle. An example of a suitable mechanism for this purpose is the mutual blocking mechanism described and claimed in United States Patent Application No. 432,491 filed September 15, 1983 in the name of the Applicant. one of the selection pushbuttons in its closed or working position when it is maneuvered and releases the selection pushbutton already operated to return to the open or rest position in response to the operation of any one button selection pushbutton in its closed or working position Thus, the mutual locking mechanism allows to operate only one of the selection pushbuttons at a given moment while the es

  other selection buttons remain inoperative.

  The operation of the television receiver 1 A according to this embodiment of the invention described above with reference to FIGS. 2, 3 and 4 can be summed up by the

following way.

  With one of the channel selection push buttons

  13 to 13 m initially maneuvered so that the switching

  29 is closed and the switch 30 is open,

  the high frequency signals received by the antenna 7 and

  The inputs to the input terminal 2a are supplied by the switch to the terminal 31 and thence to the high frequency input of the tuning circuit 10A. The manual operation of any one of the selector pushbuttons 13 to 13 m channel, the corresponding channel selection switches 19 to 19 m, 20 to 20 m are actuated in their closed position so that the corresponding tuning voltage is applied by the respective potentiometer 21 to 21 m to the circuit of tuning so that the catheter 11 of the receiver 1 A presents the video portion of the television signal broadcast on the respective channel Simultaneously, the corresponding one of the visual indicators 22 to 22 m is excited to indicate

  the channel on which the television receiver is tuned.

  The channel selector switch operated 19 to 19 m, 20 m brought in the closed position is held in this position by the mutual interlock mechanism until another channel selection pushbutton 13a, 13m is operated. or actuated, and at this time the channel selection switches corresponding to the just-operated push button are closed and the previously closed channel selection switches are released by the mutual interlock mechanism for

  return to their normal open position or rest.

13 2538980

  In the same manner, when the selector is operated and the selection switch 19 T, 20 T is closed in the closed position, any one of the channel selection switches previously held in the closed or working position is released for return to its open rest position The switch 29 is open and the switch 30 is closed, by conventional couplings (shown schematically by dashed lines in FIG. 4) so that the high frequency signal coming from the auxiliary device is transmitted to the tuning circuit With the selection switches 19 T, 20 T in the closed or working position, the resulting tuning or control voltage applied by the potentiometer 21 T to the tuning circuit 10 results in the tuning of the receiver 1A on the output frequency of the auxiliary device or video game 8, signal applied by the terminal 2b and the switch to the terminal 31 and thence to the input at high f tuning circuit 10 frequency Thus, the output of the video game 8 can

  be visualized on the cathoscope 11.

  It should be noted that according to the invention, the passage of the receiver 1 A from the display of a television signal broadcast on a selected channel to the viewing of the output of the video game 8-, requires that the maneuvering of a single element control, that is to say the operation of the selector 15 by the operator of the television receiver. Then, if it is desired to return the television receiver 1 A to the viewing of the broadcast signal broadcast on a selected channel, it is It is sufficient to manipulate a single control element. More particularly, the operation of any one of the channel selection pushbuttons 13a, 13m to close the respective channel selection switches causes the interlock mechanism to release the control switch. selecting 19 T, T to return from its working position or closed to its normal open position and to close the switch 29 and open the switch 30 to connect input terminal 2 a at terminal 31 at the high frequency input of the

chord circuit 10.

14 2538980

  FIG. 5 represents a variant of the permutation circuit replacing the switches 29 and 30 of the switching circuit 16 intended to transmit the high frequency signal of the antenna 7 or of the auxiliary device 8 in the switching circuit 16 'of FIG. , a

  high frequency relay 34 is used in place of switches

  29 or 30 of the embodiment of FIG. 4 The relay 34 is excited or not depending on the position of a switch 35 which, when closed, supplies the excitation current of the relay 34. interconnected and actuated according to the operation of the channel selection push buttons 13 to 13 m and the selector 15 by any appropriate means, not shown, so that this switch

  is opened when one of the selection pushbuttons

  channel 13 to 13 m is operated Alternatively, the

  switch 35 is closed when the selector 15 is operated.

  As a result, the excitation current is supplied by the switch 35 to the relay 34 only when the selector is actuated, that is to say when the input terminal 2b

  must be connected to the tuning circuit 10.

  The relay 34 comprises a common terminal 36 which is connected to the high-frequency signal input of the tuning circuit by a terminal 37. A permutation terminal 38 is connected to the input terminal 2a while another

  permutation terminal 39 is connected to the input terminal 2b.

  The relay 34 is made so that when it is not excited, that is to say to the operation of one of the push buttons 13 to 13 m, the common terminal 36 is connected to the permutation terminal 38 of so that a circuit exists to transmit a high frequency signal from the antenna 7 through the terminals 2a, 38, 36 and 37 to the tuning circuit 10 Alternatively, when the relay 34 is energized in response to the operating the selector 15, the common terminal 36 is connected to the permutation terminal 39 so that a circuit is now established from the video game 8 by the terminals 2b, 39, 36, 37 to transmit the signal to

  high video game frequency to the tuning circuit 10.

2538980

  Furthermore, in this embodiment of the switching circuit 16 ', a diode 40 is connected in parallel with the relay 34 To protect the circuit against overvoltages A light-emitting diode 41 is also provided in parallel with the relay 34 to indicate

  visually if the auxiliary device S has been selected.

  In other words, when the switch 35 is closed when the selector 15 is actuated, the excitation current also illuminates the light-emitting diode 41.

  42 is provided to adjust this current to the electronic diode

luminescent 41.

  The detailed description of the structure and

  The operation of the elements of the embodiment of FIGS. 6 and 7 that are identical to the elements of the embodiment of FIGS. 2 and 4 will not be repeated. It appears with reference to FIG. 6 that the receiver 1 A 'has four terminals. input 2a, 2b, 2c, 2d, the input terminal 2a being provided for the antenna 7 and the input terminal 2b for the video game 8, also on

The input terminal 2d is intended to receive a high frequency signal corresponding to a satellite telecommunication broadcast received by an antenna 44 with parabolic reflectors This signal from the antenna 44 is converted by a converter into a high frequency signal containing the image signals with a frequency corresponding to that In addition, a switching circuit 16 "is connected between the four input terminals 2a, 2b, 2c and 2d.

In addition, two switches additional 48, 49 similar to

  switches 29 and 30 are provided in the communication circuit.

More particularly, when the selector 46 or 47 is operated, the high frequency input signal from the selected terminal 2c or 2d is transmitted to the tuning circuit 10 in addition to the control voltage by terminal 28 It is understood that the selectors 46, 47 are connected to a mutual locking mechanism in the same way as the selector 15 so that a single push button of channel selection 13 to 13 m or a selector 15,46,47 is in working position or closed at a given time and that the operation of a push button 13, 13 m or a selector 15,46,47 automatically causes the push button or selector already operated to be idle. It should also be noted that, although four input terminals are used in the embodiment of FIGS. 6 and 7, other input terminals could

  be planned without the need to change the structure of the

  base and operation of the receiver 1 A '.
