`method for adapting a remote control to generate a remote
`command signal ltaving-the appropriate signal structure for
`controlling a selected one of a plurality of eleclrortic devices.
`Once the method is initiated; the remote conI:rol automati-
`cally cycles through the entire list of diiferent format com-
`mand lists stored within the remote control‘s
`internal
`memory, trarlsrrtitting a test command to the desired device
`to be controlled untiltlie user interrupts the cycle. Interrupt-
`ing the cycle of'test_comn:iands causes the remote control to
`transmit future commands using the signal st11.tctI.tre of the
`last tcstcommand transmitted prio-r'to interrupting the cycle.
`The Darhee et a.l.. U.S. Pat. No. 4,959,310 discloses a
`universal remote control system that provides for two meth-
`ods for selecting a remote control'command set.
`The first method is a step and set procedure in which the
`list of command sets stored in the remote control are stepped
`through both forward and backwards allowinga test com-
`mand from the currently selected command set to be trans-
`mitted. The user observes the efieets of the test corrunartd to
`determine ifthe currerttly selected c'onu'.nand set is compat-
`ible with the device the user is wanting to control. when the
`user finds a command set compatible with the device to be
`controlled.
`the user exits the procedure with the remote
`control set to the compatible ‘command set.
`.
`The smond method is a direct cntry—quick set procedure
`in which the user looks up the make and model of the of the
`device to be controlled from .a printed list of devices. The
`"user then directly inputs a corresponding code associated
`with the make and model of the device to he corttrolled to
`index the proper co_mma.rtd set Erorrt the remote control‘s
`internal commartd set library.

`The Takiguchi et al.. U.S. Pat. No. 5,485,149 discloses a
`method for selecting a_ set of remote control signals from.

`control signals within the remote control signal group
`assigned to the pressed key. Pressing the same key a second

`control signals.
`The remote control provides for the selection of the
`appropriate column of control signals by automatically

`transmitting a trial command. and observing the eliect ofthe
`trial command on the device to be remotely operated. when
`the desired result is observed. the user signals the remote
`control that a successful corrtmand has been transmitted. The
`remote control then eliminates lirom consideration all col-
`umns of control signals that do not contain the matched -
`successful
`trial command. If more than one column of
`control signals match the successful
`trial cox-nmand.'the
`remote control repeats the above procedure using a different
`trial command and cycling through only the remaining
`columns of control signals until all columns of command
`signals have been eliminated except one.
`
`SUMMARY OF THE ll'~lVEN'I'ION'
`
`'
`
`According to the present invention there is provided a"-
`method_ for selecting a remote control command set from a
`group of multiple command sets-stored in a remote control,‘
`for controlling various remotely controllable electronic
`devices. The method includes assigning multiple ell'ects
`observable commands (e.g. a "power oil" command) front a
`group of command sets stored in the remote control _to
`multiple user actuated switches or keys of the remote
`control.
`'
`The user then actuate: theswitches orlrcys. one at a time,
`with the corresponding assigned eifects observable com--'
`mand being transmitted. The user continues to actuate keys
`until
`the user observes the remotely controlled device.
`respondingproperly to the transmitted command. The user
`then terminates the selection procedure with the- remote
`control setting tl1e active command set to the cornmaud set
`from which the successful effects observable command was
`assigned.
`-
`By assigning a single command set to a single user.
`_ actuated key, the negative eliects of auserlrey actualion that _
`results in a double key actuation or not registering clue to '
`failure to fully actuate the key is
`If the user
`suspects the key was not fully actuated. the-user can repeat
`that particular key acmation. lfthe user inadvertently causes .
`thc remote to detect a double" key actuation. the remote"
`control merely sends the effects observable command from
`the assigned command set twice. If the user wishes to
`actuate a particular key several times in order to ooniinn its
`effect on the responding device. he may do so at any point
`during the process without afieetirlg the process.
`The ‘command sets stored in the remote oontiol can be
`permanently stored in the remote control at the time of

`command sets do not need to be searched through. Similarly
`it does ttot.requi.re the user to know all the details about a

`DESCRIIFTION OF THE PREFERRED
`EMBODINIENT
`
`'
`
`Referring now to the drawings in greater detail, there is
`illustrated in FIG. 1 a plan view of the top face of-a remote
`control Itlinoorporating the method for selecting a remote
`control command set from a group of rnultipleconmiand
`sets stored in the remote control.
`'
`T114: remote control includes a set of user achiatcti keys 12,
`including a power key l.4,'numeric ltcys l_6, mode lrcys 13,
`a magic key 10, and channel up and channel down keys 22.
`The remote control 10 further includes a visual LED 24 and
`an infrared LED {not shown). located at the front 2-6 of the
`remote conlrolltl.
`.
`FIG. 2 is a block diagram of the internal circuitry ill of the
`remote control shown in FIG. 1. The internal circuitry 28 is
`similar to the circuitry described in Escobaha et al., US. Ser.
`No. 081251 .336. filed May 31, 1994, now U.S. Pat. No.
`
`_
`
`The internal circuitry Zslinciudcs a control circuit 30. an
`oscillator circuit 32, a reset circuit 34, altey pad_circuit36,
`‘an external data input circuit 38, and an LED driver circuit .
`40.
`_
`"
`The control circuit 3|} monitors and controls the overall
`ftmctioning of the remote control Ill. In a preferred embodi-
`ment it incorporates a microprocessor -12, with associated
`semiconductor memory in the form ofROM 44 andfor RAM
`936. The semiconductor memory is used to store both pro—_
`gram operating instrtictions and program data-for assisting in
`the control of the remote control 10.
`*-
`The oscillator circuit 31 provides a clocking signal to the
`control circuit 3|}; The reset circuit 34 provides areset signal
`to the control circuit when theintemal circuitry 28 is initially _
`powered up. The key pad circuit 3t5_ incorporates the-user
`12 and provides t:i.t1:uit.ry in conjunction with
`-_ actuated lrcys
`the control circuit 30 for decoding which one of the user
`actuated keys 12 has been actuated.
`-
`'
`‘I‘he'axternal data input circuit 38 receives data from a‘
`source elite-ma] to the remote control 10. The particular
`circuitry can take the form of any one of many traditional
`forms of conununicatlon. whether wired or wireless. In one.
`preferred embodiment the external data communication is
`accomplished by a magnetic modern siruilar to the one
`described inthc Esoobosa application. l.l.S. Ser. No. 933251 ,__
`336, filed May 31, 1994. referred to above.
`The LED driver circuit -11] is coupled to the control circuit
`30 and incorporates the visual LED '24 and the irtfi-avred
`LED (not shown) located at the front 26 of the remote
`' control 10 and provides the LEDs with driving power in
`response to signals received from the control circuit 3-0. The
`visual ' LED 24 provides. the user with visual feedback
`concerning the termite control's 10 activity. The infra—red
`LED provides "the signalling capability for sending the
`remote control signals to the devices to be controlled.

`that together provide instructions for assisting in the control
`of the remote control with paiticttlat emphasis on the steps
`that provide for the method of selectinga remote control
`command set from a group of multiple command sets stored
`in the remote control.

`FIG. 3A shows the starting point of the instructionsto he
`executed by the microprocessor 42 in controlling the remote
`control 10. The flow chart begins by waiting for an interrupt
`or an indication that a key or switch 12 has been pressed or
`actuated. Upon actuation of a key or switch 12. a determi-
`nation is made as to which trey has been pressed. -
`If a mode key 18 is pressed the remote control 1|} sets the
`current conurtartd set from which commands will be trans-
`nrititcd to the command set chosen for the selected mode. Tlftc
`mode keys 18 preferably include 5ep_ara1.e mode keys-18 for
`a TV. a VCR, alcable Box. as well as any other device for
`which an infra-"red remote control transmitter could be used
`to iemotely control the device

`Upon entering the setup mode, the remote control 10 -
`waits until it receives a set up code. if the setup code is a
`setup function code; the_execulion of operaljng instructions
`of the remote control 10 branches to FIG. 3B to perform
`instructions to deterrnine which function code has been
`requested to be performed.
`'
`If the setup code is a criteria code. indicating a particular
`subset of command code sets, the remote control sets the
`searchable cornmandlsets to the command sets meeting the
`received criteria and branches the execution of instructions .'
`to FIG. 313 to perform Etructionsto select a-new command
`set for the currently active mode. I
`_
`The criteria code allows the remote control to restrict the
`,. -number of searchable cornmandsels to only those command
`- sets uscdwith deviccsroeeting a particular criteria antllor to
`determine a different order of assigning the effects observ-
`_ ablecommtmds.
`'
`_Pr'efer"ably the etlects observable commands will be
`assigned to "the user actuated keysin order "of decreasing
`popularity. However a command set that is not very popular .
`when one considers the entire list of stored command sets
`used for operating a television, may be the most popular
`cornrnandset used for operating a television manufactured
`by a particular manufacturer. The use of a criteria code
`representing a particular manufacturer by the user can be
`used to establish a dilfctetit assignment order based on the.
`popularity of command sets following the indicated criteria.
`' Examples of dilfetertt possible criteria include codes for
`dilferent manufacturers. codes for equipment manufacmred
`or purchased between a_ specified time
`devices sold
`through a particular retail outlet, etc.
`Additionally in some embodiments" it is possible to allow
`for the entry of multiple criteria in order to further isolate the
`proper command set for operating a particular device.
`lithe setup code is neither a function code not a setup
`"code. it is assumed the user inadvertently entere_d the ‘scalp
`mode and the execution of the operating instructions of the
`-;remote control 10 branches to the start of the instructions in .
`FIG. 3-A.
`FIG. 3B shows the, program steps performed when a
`functioncode is received afier entering the setup mode. First
`a determination is'rnar_le to identify-which function is being
`requested to be executed. If the function code is detenniucd
`to be a download code, the remote control executes a
`. procedure to receive one or more ccntmand sets via the
`external data input. The searcbable subset of command sets
`are defined to include the received command sets and the
`execution of the operating instructions branches to FIG." 3C.
`Similarly, an alternative embodiment can allow the
`received command sets to supplement the command sets
`previously stored in the remote control ll].
`In the embodiment disclosed in FIGS. 3A th.tough'3D the
`remote control enters a command set selection procedure
`after downloading the received data. "however it is not
`necessary for the selection procedure to be entered imme-
`_ diately after downloading of the received data. but can. be
`I delayed until the user chooses. Similarly. the data received
`'-does not necessarily have to be one‘or more command sets.
`but can include updates to already stored command sets or
`other related data.
`
`.
`
`'
`
`' it are fimetion code is a searebcode, the searehable set of
`commands is defined to include the command sets stored in
`the "remote control without first inputting a criteria code or
`downloading command sets. This allows the user to directly
`enter the-procedure tosclect the new command act without
`tirst entering a criteria code or performing another function.
`
`-
`
`.
`
`.5
`.
`FIGS. 3C and 313 shows the program steps for selecting
`the new command set from the list of seart:hab_le command
`sets. Initially, as shown in FIG. 3C a detetrnination is made
`whether the number of searchable command sets exceeds-the
`number of assignable user actuated keys or switches.
`'
`If the number of searchable command acts is greater than ,
`the number of assignable user actuated keys or switches the
`searchable command set: are broken up into multiple pages
`of conirnaztd sets no greater in size than the number of
`assignable user actuated -keys 1.ltat'ca.rt be paged through
`- using the channel up and channel down keys 22. The clfccts
`observable commands from the current1y.selected page,
`initially. the first page. of command sets is assigned to the. I
`assignable user aclustcd keys.
`If the number of searchable command sets is equal to or
`less than the number of assignable user actuated keys or
`switches. the effects observable ccrrunands from the search-
`able command sets. forruing asingle page of command sets,
`are assigned to the assignable -user actuated keys.
`_
`j
`After the cfiects observable commands for-the currently
`selected page have been assigned. the remote control I'll
`waits for a key to be pressed. When a key press has been
`detected the remote control 10 detennines if the key pressed
`is -an assignable user actuated key, altey which has had an.
`effects observable command assigned to it. If it is then the
`remote control transmits the assigned elfccts observable -.
`command (e.g.. a"'power oil" command)_to the device to be
`remotely controlled and loops back to wait for anotlier. key
`press. The user observes the device to be remotely controlled
`for a visual indication of a compatible command.
`In the preferred embodiment the assignable user actuated
`keys include the power key 14 and the numeric keys 16. The -
`assignable user actuated keys are assigrtw in the order of the
`powerltey 14 first, followed by the numeric keys 16 in order
`starting with the “onc" key and ending with the "zero" ltey.
`Additionally the preferred effects observable cotrunand is a
`powered’ command;
`'
`if the key pressed is a page down command (ie a
`down key 22). and a. subsequent page of command sets is '
`defined. Then the remote control 10 reassigns an elfects
`observable command from each of the command sets from
`the subsequent page of command sets to the assignable user
`actuated keys and loops back to wait for artotlterlrey press.
`If the key pressed is a page up command (is; a channel.-
`np key
