`ABSTRACT
`[57]
`A single, hand held remote control unit produces com
`mand signals used to control all operational aspects of a
`video tape recorder and an associated television re
`ceiver, and the video tape recorder and television re
`ceiver include switches that upon actuation can provide
`various interconnections so that all operating modes of
`the two units are possible. Actuation of the switches is
`performed by controllers, arranged at the particular
`units, and which receive the coded command signals
`from the remote control unit to set the switches in ac
`cordance with any of several keys that can be actuated
`on the remote control unit. In one aspect, depressing a
`single playback key at the remote control unit will pro
`duce coded signals received by the controllers to set the
`television receiver to an unused channel frequency and
`cause the video tape recorder to reproduce a prere
`corded video tape, with the reproduced signal fed to the

`
`BACKGROUND OF THE INVENTION
`1. Field of the Invention
`This invention relates generally to apparatus for re
`mote control of the operation of a television receiver
`and a video tape recorder and, more particularly, is
`directed to apparatus to control the operation of a tele
`vision receiver and a video tape recorder using a single
`wireless remote control unit.
`2. Description of the Prior Art
`In the use of a video tape recorder, according to the
`prior art, a conventional receiver must be connected by
`cables or wires to the video tape recorder in order to
`display the reproduced signals. The video tape recorder
`has connected to it the television antenna or leased
`video cable line, which provide the video programming
`source to be recorded. The television receiver is usually
`connected to the antenna or cable through the video
`tape recorder, so that the television receiver can receive
`and display programs independently of the video tape
`recorder.
`The video tape recorder typically has its own twelve
`channel tuner and a selector switch that permits record
`ing of one television channel signal, while passing a
`different television channel signal to the television re
`ceiver for viewing. When displaying recorded program
`material from the video tape recorder, the reproduced
`signal is modulated up to a high frequency of a standard
`television channel that has been selected beforehand,
`the channel selector of the television receiver is tuned to
`that channel, and the reproduced signal is processed and
`displayed in the conventional fashion. The channel that
`is selected for the high frequency modulation of the
`reproduced video signal, and to which the channel
`selector of the television receiver is set, is one that is a
`“dead” channel in that particular locale. That is, in
`order to avoid inter-channel interference a blank or
`unused channel is usually provided between the as
`signed television broadcast channels. The channel selec
`tor is set to one of these dead channels to receive the
`reproduced video from the video tape recorder. In the
`United States either channel 2 or 3 is selected as the
`dead channel, and in some foreign countries either
`channel 1 or 2 is selected. The high-frequency modula
`tor of the video tape recorder usually can be selected to
`modulate the reproduced video signal to a high fre
`quency corresponding to both of these two dead chan
`nels.
`In some television receivers switched connections are
`provided that permit the video signals received at the
`video tape recorder to be tuned to a desired channel
`using the video tape recorder tuner, then by-pass the
`tuner of the television receiver, and have the tuned
`video signal processed and displayed by the television
`receiver in the normal manner.
`It is also known, according to the prior art, to use a
`remote control unit to control the operation of a televi
`sion receiver. Similarly, remote control units are known
`to control the video tape recorders. These remote con
`trol units are frequently termed remote commanders.
`Early remote control units were connected by a cable to
`the unit under control, however, more recent units are
`wireless and transmit signals, such as infrared signals or
`ultrasonic signals. The remote control unit associated
`with a television receiver can usually select channels,
`raise or lower the audio volume, mute the audio, and
`
`4,527,204
`2
`turn the power to the receiver on or off. Similarly, the
`remote control unit associated with the video tape re
`corder can usually select a channel in the tuner, operate
`the various controls associated with a tape recorder,
`such as record, play, and rewind, and turn the power to
`the video tape recorder on or off.
`The video tape recorder and the television receiver
`are electrically interconnected so as to permit them to
`function in all modes, and at least two or three individ
`ual selector switches must be operated in order to set
`both units in the proper state for the particularly desired
`operating mode. Manual operation of these switches is
`very commonplace, but the use of remote control units
`has become more and more popular. Thus, for remote
`control of a video tape recorder and its associated tele
`vision receiver it is necessary to use two individual
`hand-held remote control units, each having its full
`complement of controls, and each operating indepen
`dently. The use of two individual hand-held remote
`control units is very inconvenient, requiring the manip
`ulation of two sets of controls arranged on two separate
`individual units. Not only is handling the two units
`unwieldy but using all the various switches becomes
`complicated to the point where the average consumer
`simply chooses not to use both individual remote con
`trol units.
`OBJECTS AND SUMMARY OF THE
`INVENTION
`Accordingly, it is an object of this invention to pro
`vide apparatus for controlling the operation of a video
`tape recorder and a television receiver employing a
`single remote control unit.
`It is another object of this invention to provide a
`wireless, hand-held, remote control unit for operating a
`video tape recorder and an associated television re
`ceiver to perform all functions of which both units are
`capable.
`It is still another object of this invention to provide a
`wireless, hand-held, remote control unit for a video tape
`recorder and an associated television receiver that oper
`ates in conjunction with a control system to operate
`switches located at the video tape recorder and televi
`sion receiver, respectively.
`The present invention in one aspect provides a uni
`tary wireless hand-held, remote control unit having two
`groups of function keys or switches that act to control
`the operation of the video tape recorder and its associ
`ated television receiver, respectively. The inventive
`apparatus includes control units to control selector
`switches located at interconnection nodes between sub
`assemblies and at inputs and outputs in the video tape
`recorder and the television receiver, thereby intercon
`necting the various subassemblies of the video tape
`recorder and television receiver for operating in all
`various modes. For example, in one operating mode the
`inventive apparatus connects a program source derived
`from a prerecorded video tape to be fed through a high
`frequency(radio-frequency) modulator to the tuner of
`the television receiver that has been tuned to a dead or
`empty channel, and then the video program signal is
`processed and displayed by the television receiver. In
`another mode, using the present invention the video
`tape recorder program source may be fed directly to the
`signal processing and display subsystem of the televi
`sion receiver. In still another mode using the present
`invention the program source is derived from the televi

`Television receiver 2 comprises the typical subsys
`sion antenna input of the video tape recorder and fed to
`the tuner of the television receiver, where the video
`tems and controls and includes television tuner 11, as
`signal is processed and displayed.
`well as video processing circuitry and cathode ray tube

`The above, and other objects, features, and advan
`tages of the present invention, will be apparent from the
`receiver 2 with video tape recorder 1, switch 14 is pro
`following detailed description of an illustrative embodi
`vided to select either the video output signal from con
`ment that is to be read in conjunction with the accompa
`ventional tuner 11, as connected through terminals 140
`nying drawings, in which the same reference numerals
`and 14T of switch 14, or to connect, through terminals
`identify the corresponding elements and parts in the
`14V and 140, the video signals available at video-in
`several views.
`terminal 15, which is connected to video-out terminal 8
`of video tape recorder 1.
`In the system shown in FIG. 1 of the operably inter
`connected video tape recorder 1 and television receiver
`2, when a viewer wishes to watch a program repro
`duced by the tape reproduction subsystem 3 it is neces
`sary to connect output terminal 7a of switch 7 to input
`terminal 7V and also to connect output terminal 90 to
`input terminal 9V. Switch 14 on television receiver 2
`must also be operated to connect output terminal 140 to
`input terminal 14T and television tuner 11 must be oper
`ated to select a dead channel, for example, channel 2.
`Note that in the United States, typically either channel
`2 or channel 3 will be a dead channel in almost all re
`gions due to frequency spacing requirements of the
`FCC that are intended to preclude use of adjacent chan
`nels where possible and that, although not used in the
`United States, channel 1 is used in other countries
`around the world.
`From the above it may be seen that it is quite inconve
`nient manually to make all the necessary connections
`involved in the several modes using the various selector
`switches and tuner switches. While use of the remote
`control units would eliminate manual operation of the
`various switches and controls, two separate unit is re
`quired for the video tape recorder and the television
`receiver, respectively. Manipulation of two separate
`remote control units is both cumbersome and problem
`atic from the standpoint of keeping both units at hand.
`Another mode of operation of the combined units
`shown in FIG. 1 is one in which it is desired to view a
`program on a video tape without passing the video
`through the tuner 11 of television receiver 2. In such
`case, the selector switches would be operated to set
`switch 7 to select the reproduced video signal at termi
`nal 7V and switch 14 to terminal 14V to select this
`composite video signal, provided from video-out termi
`nal 8 to video-in terminal 15. In a still different mode of
`operation, when a viewer desires to view a television
`program received by antenna 6, selector switches 9 and
`14 on the video tape recorder must be operated to make
`the appropriate interconnections as described above.
`These various modes of operation all require actuation
`of switches on both of the units and if the switching is
`desired to be done remotely, then the two separate
`remote control units are required.
`A remote control system according to one aspect of
`the present invention is shown in FIGS. 2 and 3, in
`which elements common to the system of FIG. 1 have
`like reference numerals. The present invention provides
`a single wireless, hand-held, remote control unit 16 that
`operates to control both video tape recorder 1 and tele
`vision receiver 2, simultaneously, by pressing only
`switches or buttons located on remote control unit 16.
`Remote control unit 16 produces and transmits control
`signals received by control unit 17 to control selector
`switches 7 and 9 of the video tape recorder 1, and re
`mote control unit 16 also produces and transmits con
`trol signals received by control unit 18 to control selec
`
`DESCRIPTION OF A PREFERRED
`EMBODIMENT
`Referring to the drawings in detail and, initially, to
`FIG. 1 thereof, it can be seen that video tape recorder
`1 is operably connected to television receiver 2. Video
`tape recorder 1 has main video tape record and repro
`duction unit 3 that includes all of the electro-mechanical
`elements necessary to record and reproduce video sig
`nals on a magnetic tape. Video tape recorder 1 also
`includes high-frequency modulator 4 that converts a
`received raw video signal, as might be supplied from
`tape reproduction unit 3, into a modulated signal at
`radio frequency (RF) of an arbitrary channel, prefera
`bly a dead channel such as channel 2 or 3 in the United
`States or channel 1 or 2, elsewhere. Video tape recorder
`1 also includes tuner section 5 which is substantially
`identical to a conventional television receiver tuner and
`has all the well-known elements thereof. The signal
`input to tuner 5 is supplied by television antenna 6 con
`nected at antenna input terminal 60. Selector switch 7 is
`provided to select the program source and, in that re
`gard, operating switch 7 connects switch output termi
`nal 7a to a composite video signal as provided from
`video tape reproduction unit 3 at terminal 7V or from
`television tuner 5 at terminal 7T. Thus, by action of
`switch 7, composite video signals from one of two
`sources are fed to RF modulator 4 and are also fed to
`video-out terminal 8. A second selector switch 9 is
`provided in video tape recorder 1 that feeds signals to
`output terminal 10, to which television receiver 2 is
`connected. More speci?cally, in a ?rst position the
`output from RF modulator 4 at terminal 9V is con
`nected to switch terminal 90 to provide a radio-fre
`quency modulated signal at output terminal 10 at a
`frequency of a selected local dead channel. In a second
`position of selector switch 9, terminal 9a is connected to
`terminal 9T that is directly connected to television an
`tenna 6. Thus, by operation of switch 9, it is possible to
`have either a radio-frequency modulated composite
`video signal or a raw video signal, as might be received
`from television antenna 6, connected directly to output
`terminal 10 of video recorder 1.

`tor switch 14 of television receiver 2 and also to control
`channel selection in television receiver tuner 11.
`Control units 17 and 18 can be built according to any
`of several conventional designs for controllers of this
`kind. For example, mechanical operation of the various
`switches can be accomplished by solenoids or stepper
`motors, alternatively, “soft” switching could be accom
`plished by solid-state devices. Operation of either of
`these two exemplary embodiments can be initiated by
`receiving the appropriate command signals from re
`mote control unit 16. The command signals can be infra
`red signals received in “line of sight” by the control
`unit, with differentiation among the several command
`signals accomplished by coding of the command sig
`nals. Again, any of several of the conventional kinds of
`signal coding can be advantageously utilized.
`The command buttons of remote control unit 16 are
`arranged as shown in FIG. 3 and, more specifically,
`play button 190 is provided to place video tape recorder
`1 in a playback mode, that is, to cause tape reproduction
`unit 3 to produce appropriate video output signals.
`Remote unit 16 is also provided with power switch 1%,
`which acts to turn on or off video tape recorder one.
`Button 190 also pertains to video tape recorder 1 and
`acts as the stop button to stop reproduction unit 3 from
`producing output signals. Button 19d is a record button
`that activates video tape recorder 1 to record incoming
`video signals. In the interest of clarity, the various con
`nections for the tape unit 3 to permit it to record incom
`ing video signals are not shown, that is, the connection
`between the output of video tape recorder tuner 5 and
`the input of video record unit 3 is not shown. Buttons
`19e and 19f initiate the well-known fast forward and
`rewind functions, respectively. Buttons 19g and 19h are
`the channel select buttons and cause tuner 5 of video
`tape recorder to scan up or down, respectively. Button
`191‘ is a pause button that will cause the tape record and
`reproduction 3 of video tape recorder 1 to momentarily
`stop, whether recording or reproducing video signals.
`Button 19j is a monitor switch for supplying a repro
`duced signal from video tape recorder 1 to television
`receiver 2 through the line connected between video
`out terminal 8 and video-in terminal 15. Button 19k is a
`locking switch that prohibits operation of other control
`buttons on remote command unit 16 when recording
`button 19d has been depressed.
`The control buttons in the lower section portion of
`remote command unit 16 control television receiver 2
`and all utilize the prefix number 20. More speci?cally,
`20a is the power on/off button for television receiver 2
`and switches 201 through 2012 are all channel select
`buttons corresponding to the twelve possible channels
`available in typical television receivers. Note that in this
`embodiment the channel numbers run from one to
`twelve, whereas in conventional televisions utilized in
`the United States the channel numbers run from two
`through thirteen. Buttons 20b and 200 are the audio
`volume controls and serve to cause the volume to be
`increased or decreased, respectively.
`The operation of many of the above-described con
`trols relative to both the video tape recorder and to the
`television receiver 2 is straight forward and well
`known. The present invention provides two internally
`arranged controllers 17 and 18 operating to control the
`selector switches of the video tape recorder 1 and the
`television receiver 2, respectively, and remote com
`mand unit 16 produces and transmits the appropriate
`control signals to operate these two controllers. When
`
`4,527,204
`6
`play button 190 is depressed, remote command unit 16
`transmits two individual and identifiable control signals
`So and S1, as indicated, these signals are preferably infra
`red radiation signals that are received by controllers 17
`and 18. Command signal S0 is received by controller 17
`that controls the connection state of switches 7 and 9.
`More speci?cally, depressing play button 19a causes
`com-mand signal S0 to be produced and received at
`controller 17, which acts to ‘connect terminals 7V and
`7a of switch 7 and to connect terminals 9a and 9V of
`switch 9. Signal S1 is detected by controller 18, which
`operates switch 14 to connect contact 140 with contact
`141' and sets television receiver tuner 11 to a dead chan
`nel, which in this example is channel 2. Thus, the output
`signals from video tape recorder tape unit 3 may be fed
`to the video signal processor and cathode ray tube dis
`play 12 of television receiver 2 by depressing only one
`button (play button 190) on combined remote command
`unit 16. Additionally, there is the option of manually
`connecting antenna 6 to output terminal 10 of video
`tape recorder 1 by manually moving selector switch 9
`to connect terminals 9T and 9a.
`When it is desired to monitor the video signal being
`recorded on video tape by unit 3 of video tape recorder
`2, monitor button 19]‘ is depressed. The signal path from
`video-out terminal 8 and video-in terminal 15 of video
`tape recorder 1 and television receiver 2, respectively,
`is used in the tape monitor mode. Pressing of monitor
`button 19j causes remote command unit 16 to produce
`and transmit two individual signals, S2 and S3. The
`signal S; is detected by controller 17 that operates
`switch 7 to connect terminal 7T with terminal 7a and
`controller 17 also operates switch 9 to connect termi
`nals 9T and 9a. Note that the switch connections to
`permit tape record and reproduce unit 3 to record are
`not shown in the interest of clarity. The signal path to
`monitor the signal from tuner 5 that is being recorded in
`tape record unit 3 is from switch terminal 70 to video
`out terminal 8. Controller 18 receives control signal S3
`and operates switch 14 to connect input terminal 14V
`with switch output terminal 14a, in order to connect the
`video-in signal at terminal 15 to video processing and
`cathode ray tube display subassembly 12.
`When the viewer desires to view a television pro
`gram received at antenna 6, he may operate switch 14 to
`connect terminals 14T and 14a, thereby feeding the
`signal received by antenna 6 through television receiver
`tuner 11 to display unit 12. Note that switch 9 had been
`previously actuated by signal S; to connect terminals 9a
`and 9T, thus providing the received video signal at
`antenna terminal 10 of video tape recorder 1.
`The above explanation of one aspect of the invention
`has been directed to the operation of a video tape re
`corder as the principal program source, with the unit
`being controlled remotely by the inventive apparatus.
`This function is not exclusive and remote control unit
`16 is also used to control television receiver 2, for exam
`ple, when any one of the channel selecting buttons 201
`through 2012 are depressed, switch 9 in video tape
`recorder 1 is also actuated. Moreover, when the dead
`channel is selected by the appropriate channel selecting
`button, for example, if channel 2 is a dead channel,
`switch 202 is depressed, then remote command unit 16
`generates signals S4 and SCI-11. Signal S4 is received by
`controller 17 and operates switch 9 to connect contact
`90 with contact 9V, which is the output of RF modula
`tor 4. Signal SCH; is detected by controller 18 and actu
`ates tuner 11 of television receiver 2 to select the dead

`In order to summarize the various signals produced
`tuner 11 of television receiver 2. When any channel is
`and transmitted by remote command unit 16 in response
`selected other than the predetermined dead channel,
`to the operator pressing the various buttons thereon, it
`which in this example is channel 2, remote control com
`is noted that when depressing play button 190, and
`mand unit 16 generates signals S5 and SCH", where n is
`when switch 22 is arranged at the RFCHI position,
`any of the remaining channels that is, channels 1, 3, 4,
`signals SQ and S6 are produced, when switch 220 is in the
`up to 12. Signal 85 is received'by controller 17 and sets
`RFCI-IZ position, signals SQ and S3 are produced. De
`switch 9 to connect output terminal 90 with antenna
`pressing monitor switch 19] causes remote control unit
`terminal 9T. Signal SCH" is received by-controller 18,
`16 to produce signals 5; and S3. When switch 22 is set at
`which acts to set tuner 11 to tune the channel corre
`the RFCH2 position, depressing button 20; produces
`sponding to the particular button that was selected on
`signals S4 and Sam, pressing any of the other channel
`remote command unit 16, that is, 201 or 203 through
`2012. By following the above teaching of the present
`buttons, that is, buttons 201 or 203 through 2012, will
`result in the production of signal S5 and S53", where n
