Abstract

Two or more input terminals 2a, 2b are provided for receiving respective RF input signals from an antenna 7 and an auxiliary device 8, such as a personal computer or a video game. The second input terminal 26 is on the front of the receiver for improved ease of connecting and disconnecting the auxiliary device. For selecting either one of broadcast signals received at the first input terminal or the auxiliary signal from the second input terminal, the television receiver has a plurality of manually actuable channel selecting switches 13a-13m having switch contacts (19a- 19m 20a 20m Figures 4 and 7) and a manually actuable second terminal selecting switch 15 having switch contacts (19T 20T) so that the receiver is tuned for the signal frequency corresponding to the actuated switch and a change over switch 16 selects the appropriate input 2a, or 2b. An interlock arrangement insures that only one switch at a time is actuated. The television receiver may have additional input terminals (2c and 2d Figures 6 and 7) for receiving similarly selected external signals, each having a characteristic frequency, from, for example, a directional antenna or a dish antenna receiving a satellite telecommunications broadcast. <IMAGE>

Description

SPECIFICATION Television Receiver This invention relates generally to television receivers and, more particularly, is directed to a television receiver for receiving 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 conventional television receiver so that the picture tube of the receiver may serve as a display device for the video game or personal computer: In this way, the extra expense and wasted space of providing a separate picture tube or CRT for the personal computer or video game are avoided. In addition, the availability of dish antennas has made possible the directrecep- tion of satellite telecommunications broadcasts in individual homes, provided the dish antenna may be conveniently connected to the television receiver.

A conventional television receiver according to the prior art has a single input terminal for connection to an antenna. The antenna receives a plurality of RF broadcast channel signals corresponding to different television stations, or channels, and one of the broadcast signals is selected for display on the picture tube by selective actuation of the pushbuttons or a dial mounted on the receiver for easy access. A tuning stage in the television receiver responds to actuation of a push-button, for example, in response to a characteristictuning voltage provided by actuation of the push-button, fortuning the receiverto a particular channel.

To use the television receiver as a display device for a video game, for example, the output cable of the video game must be connected to the television receiver through the input terminal of the latter and one of the channel-selecting push-buttons must be actuated to tune the receiver for the RF frequency characteristic of the video game output. In order to avoid the necessity of physically disconnecting the antenna and attaching the output cable of the video game to the television receivereverytime it is desired tochangefromonetotheother, an externalorauxiliary switching device has been proposed as an accessory interposed between the receiver input terminal and the antenna and video game or personal computer.In one condition of the switching device, the antenna is connected to the receiver input terminal and one ofthe channel-selecting push-buttons on the receiver may be actuated to select the television signal being broadcast by the respective channel for display on the CRT. In another condition of the auxiliary switching device established by actuation of a condition-selecting push-button or actuating knob on the switching device, the output cable of the video game or personal computer is connected to the receiver input terminal, and another of the channelselecting push-buttons, for example, one associated with a channel not received at the location of the television receiver, is actuated to tune the receiver for the frequency of the output of the video game or computer.

However, the operation of this prior art apparatus presents distinct disadvantages. This apparatus employs switches or push-buttons on two separate objects, that is, the channel-selecting push-buttons on the television receiver and the condition-selecting push-button or knob on the switching device.

Change-overfr6mwatching a particuiar TV station to playing a video game requires operation of the condition selecting push-button on the terminal switching device or accessory, and also actuation of the one of the channel selecting push-buttons corresponding to tuning for the frequency of the video game output.

Similarly, change-over from playing the video game to receiving a desired station orchannel on the television receiver requires first that the conditionselecting push-button of the switching device be operated to connect the antenna with the receiver input terminal and then one of the channel-selecting push-buttons must be operated to select the desired channel. Thus, two operations are necessary in changing over from one to the other of the display of the video game and the display of the desired channel.

Additionally, since the prior art apparatus requires two independent devices or housings, that is, the television receiver and the switching device or accessory,the resulting combination may be unsightly and may take up more spacethan a userwishesto employ for that purpose. Also, it might be necessary, in some instances, to install the switching device at a distance from the television receiver, and the resulting inconvenience to the user in walking back and forth between the two is likely to create consumer dissatisfaction.

These same disadvantages apply to the changeover from watching a particular TV station to viewing a signal from a directional antenna employed for removing ghost images or from a dish antenna for receiving a satellite telecommunications broadcast.

In accordance with an aspect of this invention, a television receiver includes at least two input terminals for receiving respective input signals, an antenna connected to a first of these terminals for applying an antenna input signal thereto, a second of these input terminals being located on a front panel of the cabinet of the receiver and adapted for connection to an auxiliary input device, such as, a video game or a computer, for receiving an auxiliary input signal from the latfer, input terminal selection means for selecting one of these terminals as a selected terminal, and control means cooperating with the terminal selec tion means for tuning the receiver to present a display corresponding to an input signal applied to the selected terminal.

The above, and other objects, features and advantages of the invention will be apparent in the following detailed description of illustrative embodiments of the invention, which is to be read in connection with the accompanying drawings.

Figure 1 is a schematic side elevational view of a television receiver and separate switching device accardingto the prior art; Figure 2 is a schematic side elevational view of a television receiver according to a first embodiment of the present invention: Figure 3 is a schematic front elevational view of the television receiver of Figure 2; Figure 4 is a circuit diagram shown a principal part of the television receiver of Figure 2; Figure 5 is a circuit diagram showing a principal part in a modification of the television receiver of Figure 2 according to this invention; Figure 6 is a schematic side elevational view of a television receiver according to a second embodiment of the present invention; and Figure 7 is a circuit diagram showing a principal part of the television receiver of Figure 6.

Before proceeding with a detailed description of the invention, reference will be made to Figure 1 as showing an arrangement according to the prior art for selectively applying a plurality of inputs to a television receiver 1 having a single input terminal 2, In such prior art arrangement, a switching device 3 is provided apart from, or as an external accessory for television receiver 1 and has an output terminal 3a connected to the television receiver 1 via a cable 4 connectedto inputterminal2.Theantennaswitching device 3 further has two input terminals 5 and 6. A conventional antenna 7 for receiving broadcast signals on different channels or stations is connected to switching device 3 through input terminal 5, while an auxiliary input device, shown as a video game 8, is connected to input terminal 6 of switching device 3 via an output cable 9.A condition selecting button (not illustrated) on switching device 3 is actuable to select either input termnal 5 or input terminal 6, that is, either an antenna input signal or game input signal, respectively, for connection through output 3a to receiver input terminal 2. The signal received at input terminal 2 is transmitted to tuner 10 by conventional means. The television receiver 1 also has a CRT 11 and a number of channel selecting push-buttons (not illustrated) corresponding to the various teievision stations or channels. It will be appreciated that the push-buttons are selectively actuable to tune the receiver for the RF frequencies with which television signals are broadcast in the respective channels.

Further, one of the push-buttons, preferably one corresponding to a channel which is not receivable atthe location of the television receiver, is actuable to tune the receiver for the RF frequency of the output from the video game 8 or other auxiliary input device.

In the operation of this prior art arrangement, receiver 1 may be used as a conventional television receiver when the condition-selecting push-button is in the position to select input terminal 5 of switching device 3. In such case, any antenna input or broadcast signal received by antenna 7 may be displayed on CRT 11 by operation ofthe appropriate channel selection push-button to tune the receiver accordingly.

Alternatively, the condition selecting button may be moved to select input terminal 6 which receives the output signal from video game 8. In that case, the one of the channel-selecting push-buttons which is aperable for tuning the receiver 1 to the RF frequency of the output from video game 8 must also be actuated.

Similarly, change-over from displaying the auxiliary signal from video game 8 to displaying a broadcast television signal from a selected channel or station requires first the actuation of the condition selecting button on switching device 3 for again applying the antenna signal to input terminal 2 and then the further actuation of one of the push-buttons for selecting the desired channel. If the television receiver 1 and switching device 3 are remote from each other, the actuation of push-buttons on both the receiver and switching device can prove quite inconvenient.

Further, the provision of switching device 3 as an accessory or separate component external from the television receiver can result in a cluttered or unsightly appearance and in an undesirable increase in the space required therefor. Frequently, in order to avoid such unsightly appearance, the switching device 3 is often disposed in back of the receiver 1, but that only adds to the inconvenience involved in changing over from one input signal source to another.

Referring now to Figure 2, in which elements corresponding to those described above with reference to the prior art arrangement of Figure 1 are identified by the same reference numerals, it will be seen that a television receiver 1A according to an embodiment of this invention has a CRT 11 for displaying a selected one of input signals applied to input terminals 2a and 2b. More particularly, input terminal 2a, shown disposed at the back of receiver 1A, is adapted to be connected to an antenna 7 for receiving broadcast signalstherefrom, and inputterminal 2b is adapted to be connected by cable 9 to video game 8 for receiving the output signal from the latter. In accordance with this invention, input terminal 2b is located on a front panel 12 of receiver 1A so that the video game 8 or other auxiliary input device may be readily connected or disconnected.

Mounted at the front of television receiver 1A is a channel selector assembly 13 shown to include a plurality of VHF channel selecting push-buttons 13a-13/ and a UHF channel selecting push-button 1 3m, which are selectively actuable or depressible for tuning the receiver to a respective channel. Also on the front panel 12 is an on-off power switch 14.

Additionally, on the front panel 12 of receiver 1A is an input terminal selector 15, shown in the form of a push-button, which is operable to select inputterminal 2b by manual actuation in the same mannerthat a particular channel is selected so that the receiver is tuned to the characteristic frequency corresponding to the signal from the auxiliary device. It will, of course, be understood that more than two input terminals could be provided on a television receiver according to the present invention, and in a second embodiment discussed hereinafter, selectors are provided to select any one of these additional input terminals.

The terminal selector 15 is desirably located at the front of television receiver 1A adjacent or near to channel selector assembly 13 so asto form a unified selection panel therewith, as may be seen in Figure 3.

The selection panel further includes a volume control 17. The channel selecting push-buttons 13a-13m and the selector 15 control the tuning of the television receiver 1Ato display either a television signal broadcast on a particular channel orthe output of the video game 8.

Input terminals 2a and 2b are both connected to a switching circuit 16, which provides the means by which a selected signal from either of the terminals is transmitted to a conventional tuning stage or tuner 10 and also provides an appropriate control voltage Vc to the tuner 10 for tuning the receiver to display the selected signal. More particularly, the tuner ortuning stage 10 (Figure 2) may include, for example, a varactor (not shown), that is, an analog voltage controlled variable reactance device, such as, a variable capacitance diode, employed as the tuning element, and the control voltage Vc therefor is obtained by means of a potentiometer array.

In the embodiment of this invention shown in Figure 4, such a potentiometer array is provided in the channel selector assembly comprised of tuning voltage sections, of which sections 18a and 18m, which correspond to the channel selecting push-buttons 13a and 13m, respectively, and an additional tuning voltage section 1 8T associated with selector 15, are illustrated. Of course, one tuning voltage section is provided for each channel represented in the assembly 13.

The tuning voltage sections 18a...18m, 18T are shown to be similar in construction and are comprised respectively of selecting switches 19a...19m, 19T, and 20a...20m, 20T, potentiometers 21a...21m, 21T, respectively, and visual indicators 22a...22m, 22T, respectively, for example, in the form of neon lights or LEDs. Tuning voltage sections 18a...18m, 18T further include triple pole change-over switches 23a...23m, and 23T, respectively, for connection to lines L, H and U corresponding to the frequency bands for low frequency channels 1-3, high frequency channels 4-13, and UHF, respectively. These lines L, H and U are connected to the tuner 10 by conventional circuitry (not illustrated) and are conventionally used, with the control voltage Vc to provide broad tuning capability to the receiver over a wide range of frequencies.

Since the tuning voltage sections 18a...18m and 18T (and the remaining, unillustrated sections corresponding to the other channels) are similar, only the interconnections and operations of switches 19a, 20a, potentiometer 21a, visual indicator 22a and change-over switch 23a in section 18a will be described in detail, and it will be understood that the interconnections and operations of the corresponding components in the other sections are generally the same.

In tuning voltage section 18a, normally open switches 19a and 20a are constructed or ganged to open and close together. The resistance element 24a of potentiometer 21a is connected between a termi nal 25 connected to a source of operating voltage +Vp (which may be -33V) and a terminal 26 connected to ground. The visual indicator 22a is connected in series with switch 20a between a terminal 27 connected to a suitable source of operating voltage +VN and a terminal connected to line U, H or L, as appropriate for the selected channel.

Upon the simultaneous closing of the normally open switches 19a and 20a, a suitable predetermined tuning voltage Vc is obtained at the movable tap of potentiometer 21a and transmitted through closed switch 1 9a for application as a control voltage to tuner 10 (not illustrated in Figure 4) through terminal 28, so that the tuner 10 tunes the television receiver lAfor a corresponding RF input signal. The closing of switch 20a causes energizing of visual indicator 22a for displaying the information that the television receiver is tuned forthe channel to which the section 1 8a corresponds.Of course, the potentiometers 21a, 21m, 21T have their respective movable taps positioned so that different control voltages will be applied to tuner 10 upon the selective closing of the switches of the respective tuning sections. For example, the potentiometers 21a, 1m desirably have their movable taps positioned so that the control voltages applied to tuner 10 upon the closing of their respective switches will result in the tuning of receiver 1A for the RF frequencies at which television signals are broadcast in the various channels. Accordingly, the switches 19a...19m and 20a...20m constitute channel selection switches, in that the closing of any one pair of switches is effective to cause tuning of the receiver 1A for the respective broadcast channel.These channel selection switches are suitably actuable from their normaliy open or inoperative positions to their closed or operative positions for selecting the respective channels in response to the selective depressing or operation of push-buttons 13a...13m, respectively.

On the other hand, switches 19T and 20T, having the same structure as just discussed, operate to tune the receiver 1 A to display the auxiliary input signal. It will be appreciated that the movable tap of potentiometer 21 T is positioned so that, when switches 1 9T and 20T are closed, the tuning or control voltage applied from potentiometer 21 Ttotuner 10 will result in the tuning of receiver 1 Aforthe RF frequency ofthe output from video game 8.

The input signals from terminals 2a and 2b are selectively transmitted to the tuner 10 through change-over switches 29 and 30, which are included in switching circuit 16. When input terminal 2a has been selected by the actuation of one of the channel selecting pushbuttons 13a, 13m, change-over switch 30 is suitably opened and change-over switch 29 is closed in addition to the respective switches in the tuning section 1 8a .1 8m associated with the selected channel. The input signal received by the antenna is then transmitted through closed switch 29 to a terminal 31 and then to the tuner 10 as is the appropriate control voltage Vc through terminal 28.Alternatively, when selector 15 is actuated sothatinputterminal 2b is selected to transmitthe signal from the video game 8, change-over switch 29 is opened and change-over switch 30 is closed along with the switches in tuning section 18T and the auxiliary input signal and the appropriate control voltage Vc are transmitted to the tuner 10 through terminals 31 and 28 respectively.

Also included in switching circuit 16 are condensers 32 and 33 which serve as insulators forthe "hot chas- sis" of the receiver.

The channel selecting pushbuttons 13a...13m and the selector 15 are suitably constructed so that only one will be activated at any one time and so that the activation of one will automatically result in the deactivation of the others. An example of an appropriate mechanism for this purpose is the interlock mechanism disclosed and claimed in applicant's copending application Serial No. 432,491, filed September 15, 1983, and assigned to the same assignee, which disclosure is herein incorporated by reference. Such interlock mechanism retains any one of the selection pushbuttons in its closed or operative position upon the actuation thereof to such operative position, and releases a previously actuated selection pushbutton for return to its normal open or inoperative position in response to the actuation of any other one of the selection pushbuttons to its closed or operative position.Thus, the interlock mechanism is effective to provide for the operation of only one of the selection pushbuttons at any one time while the other selection pushbuttons remain inoperative.

The operations of the television receiver lAaccord- ing to the embodiment of this invention described above with reference to Figures 2, 3 and 4 will be summarized as follows: With one of the channel selection pushbuttons 1 3a...1 3m initially actuated so that switch 29 is closed and switch 30 is open, RF signals received by antenna 7 and applied to input terminal 2a are supplied through switch 30 to terminal 31 and thence to the RF input of tuner 10.Upon the manual actuation or depression of any one of the channel selecting pushbuttons 13a...13m, the corresponding channel selection switches 19a...19m, 20a...20m are actuated to their closed positions for causing a corresponding tuning voltage to be applied from the respective potentiometer 21a...21m to tuner 10 so that the CRT 11 of receiver 1A will display the video portion of the television signal being broadcast on the respective channel. Simultaneously, the corresponding one of the visual indicators 22a...22m will be energized for indicating the channel to which the television receiver is tuned.The activated channel selection switches 19a...19m, 20a...20m, moved to their closed positions, will be retained thereat by the interlock mechanism until such time as another of the channel selecting push-buttons 13a, 13m is depressed or actuated, whereupon the channel selection switches corresponding to the newly actuated push-button will be closed, and the previously closed channel selection switches will be released by the interlock mechanism for return to their normal open or inoperative position.

In the same manner, upon the manual actuation of the selector 15 and the resulting closing of selection switches 1 9T, 20Tto their closed positions, any one of the channel selection switches previously held in its closed or operative position is released for return to its inoperative or open position. Switch 29 is opened and switch 30 is closed, by means of conventional connections (schematically indicated by the dotted lines in Figure 4), sothatthe RFsignal from the auxiliary device is transmitted to the tuner.With selection switches 19T, 20T in their closed or operative positions, the resulting tuning or control voltage applied from potentiometer 21T to tuner 10 is effective to causetuning ofreceiverlAforthefrequencyoftheRF output from the auxiliary device or video game 8then being applied through terminal 2b and switch 30 to terminal 31 and thence to the RF input of tuner 10.

Thus, the output of video game 8 can then be displayed on CRT 11.

It will be appreciated that the change-over of receiver 1A according to this invention from the display of a television signal being broadcast on a selected channel to the display of the output of video game 8 conveniently requires only the actuation of a single control member, that is, the actuation of selector 15 by the operator of the television receiver.

Thereafter, when it is desired to return the television receiver 1A to the displaying of the television signal being broadcast on a selected channel, it is again only necessary to actuate a single control member. More specifically, the depressing or actuation of any one of the channel selecting push-buttons 13a, 13m for close ing the respective channel selection switches cause the interlock mechanism to release selection switch 19T, 20T for return from their operative or closed position to their normal open position and to close switch 29 and open switch 30 to cause the connection of input terminal 2a through terminal 31 to the RF input of tuner 10.

An alternative change-over circuit in place of switches 29 and 30 in switching circuit 16fortransmit- ting the RF signal from either the antenna 7 or the auxiliary device 8 is shown in Figure 5. In the switching circuit 161 of Figure 5, a high frequency relay 34 is now employed in place of the switches 29 and 30 of the embodiment shown in Figure 4. The relay 34 is excited or not dependent on the position of a switch 35 which, when closed, provides the exciting current for operation of the relay 34. Switch 35 is interconnected and operated in accordance with activation of the channel selecting push buttons 13a...13m and selector 15 by any suitable means (not illustrated) such that switch 35 is open when one of the channel selecting pushbuttons 13a...13m is actuated. Alternatively, switch 35 is closed when selector 15 is actuated.As a result, the exciting current is supplied through switch 35 to relay 34 only when selector 15 is actuated, i.e. when input terminal 2b is to be connected to the tuner 10.

Relay 34 has a common terminal 36 which is connected to the RF signal input of the tuner through a terminal 37. A change-over terminal 38 is connected to the input terminal 2a, while another change-over terminal 39 is connected to input terminal 2b. The relay 34 is so constructed that, when it is unexcited, that is, upon actuation of one of the pushbuttons 13a...13m, the common terminal 36 is connected to change-over terminal 38, so that a path exists for transmitting an RFsignal from the antenna 7through terminals 2a, 38, 36 and 37 to the tuner 10. Alternatively, when relay 34 is excited in response to actuation of selector 15, the common terminal 36 is con nectedto change-overterminal 39, so that a path now extends from video game 8 through terminals 20, 39, 36, 37 to transmit the RF signal from the video game to the tuner 10.

Additionally, in this construction of switching circuit 161, a diode 40 is connected in parallel with relay 34 for protection of the circuit against voltage spikes.

A light emitting diode (LED) 41 is also provided in parallel with relay 34 for providing a visual indication of whether the auxiliary device 8 has been selected.

That is, when switch 35 is closed in response to actuation ofthe selector 15, the exciting current also serves to iiluminate the LED 41. A resistor 42 is provided for regulating this current to the LED 41.

A further development of a television receiver 1 according to the present invention is shown in Figures 6 and 7. The structure of this embodiment is similar to the embodiment shown in Figures 2-4, and corresponding parts have been given the same reference numerals. Detailed description of the structure and operation of those parts of the embodiment of Figures 6 and 7 which are identical to parts of the embodiment shown in Figures 2-4 will not be repeated here. It may be seen in Figures 6thatthe receiver 1A' has four input terminals 2a, 20, 2c, 2d, with input terminal 2a being for the antenna 7, and inputterminal 2b being for the video game 8, and again located on the front panel 12 of the receiver 1A' for easy access.Input terminal 2c is adapted to receive an RF signal from a directional antenna 43, which may advantageously be employed to eliminate ghost signals from the CRT display. Input terminal 2d is adapted to receive an RF signal corresponding to a satellite telecommunications broadcast received at a dish antenna 44. This signal from dish antenna 44 is converted by a converter45 into an RFsignalcontain- ing the video signals with a frequency corresponding to that of an unoccupied channel. Further, as shown, a switching circuit 16-'6" is connected between all four input terminals 2a, 2b, 2c and 2d and the tuner 10.

On the front panel 12 of the television receiver 1Al, in addition to the channel selection push buttons 13a...13m and the selector 15, two additional input terminal selectors 46, 47 are provided in the form of push-buttons actuable for the selection of input terminals 2c, 2d respectively.

The tuning circuit for this embodiment, as seen in Figure 7, is similar in construction to that shown in Figure 4. In Figure 7, however, two additional tuning voltage sections 18R and 18S are provided so that, when selector 46 or 47 is actuated to select the signal received at input terminals 2c or 2d, respectively, switches 19R, 20R or 19S, 20S are closed so that an appropriate control voltage, corresponding to that of a chosen, unoccupied channel, will be transmitted to the tuner 10, in the same manner as discussed in the previous embodiment. Further, two additional switches 48, 49, similar to switches 29 and 30, are provided in switching circuit 16'5" for selecting the input signal which is transmitted to terminal 31.More particularly, when selector 46 or 47 is actuated, the input RF signal from the selected terminal 2c or 2dwill be transmitted to the tuner 10 in addition to the control voltage through terminal 28. Of course, it will be understood that selectors 46, 47 are connected with an interlock mechanism in the same manner as selec tor 15, so that only one channel selecting push button 13a...13m or selector 15,46,47 will be in its operative or closed position at any time, and that the actuation of any push button 13a,13m orselector 15,46,47 will automatically result in the deactivation of any previ ously actuated push button or selector.It will also be appreciated that, while four input terminals are utilized in the embodiment of Figures 6-7, additional input terminals may be provided without requiring any change in the basic structure and operation ofthe receiver 1A'.

In this embodiment, input terminal 2b is again on the front panel 12 of the receiver 1 A for easy connection of the video game 8, so that many different games, or a personal computer, may be alternatively operated with a display on CRT 11. However, input terminals 2c and 2d are shown located at the rear of the receiver 1A1 because of the relatively permanent nature of their antenna connections. It will be appreciated that, if desired, additional input terminals may be located on the front panel 12 of the receiver 1AX when it is important to provide for easy access and connection, as in the case of input terminal 20.

It will be appreciated from the foregoing that, in the various described embodiments of this invention, change-over of the television receiver between the condition for displaying a broadcast television signal orother input applied to terminal 2a and the condition for displaying the output of a video game or other auxiliary device applied to input terminal 2b, can be conveniently and simply effected at the television receiver itself. Further, since switching accessories independent of the television receiver are not employed for effecting the foregoing change-over, a desirably uncluttered appearance of the receiver is achieved.

Although illustrative embodiments ofthe invention have been described in detail herein with reference to accompanying drawings, it is to be understood that the invention is not limited to those precise embodiments, and that various changes and modifications may be effected therein by one skilled in the art without departing from the scope or spirit ofthe invention as defined in the appended claims.
