Definitions

  • the present invention relates to universal remote controls. More particularly, the present invention is a method and apparatus for causing a remote controller to execute a sequence of instructions at a preprogrammed time.
  • a reconfigurable remote control transmitter is a transmitter used to control a plurality of remotely controlled products. Often, each of a plurality of products can be controlled from its own associated remote control transmitter. For example, there may be one remote control transmitter associated with a television receiver, another associated with a video cassette recorder and another associated with a turntable of a stereo system.
  • the reconfigurable remote control transmitter is capable of learning the signals (typically infrared (I/R) signals) used by a plurality of such remote control devices so that a single remote control transmitter can be used to control a plurality of products.
  • I/R infrared
  • a common problem which users of remotely controlled devices encounter when attempting to use their components during their absence is the need to turn on and off various components of their system. This is particularly true in the case of recording devices. For example, it may be desireable to record a television show when the user is not present.
  • One technique for overcoming this problem is for the user to set the VCR's internal timer functions to record while he is away.
  • the problem with using this feature of the VCR is that other components of the system may need to be turned on before recording begins. For example, if a cable box and television are connected to the system, each of these devices must be turned on in order to record from a particular station. Therefore, using the VCR's internal timer functions will not permit recording unless the other components of the system are left on for the entire time during the user's absence.
  • Another example of component adjustments which may need to be made during the user's absence is the need to adjust a satellite dish. If the satellite must be moved to a different position for maximum reception of a particular station, this function must be carried out before recording begins. This situation may arise where more than one recording session from more than one station is desired during the user's absence.
  • the present invention is a method and apparatus for remotely controlling a system to allow for operation of system components during the absence of the user.
  • a universal remote control which can control the various components of the system includes a timer for keeping track of a selected duration of time.
  • the remote control can store a sequence of instructions to be performed at a preprogrammed time at the depression of a single key. Upon depressing this key, the remote controller will turn on the various necessary system components at a desired time and turn them off after a selected duration of time.
  • This universal remote control overcomes the problem of leaving system components on while the user is absent. Further, a satellite dish can be manipulated to a desired position and a program can be recorded without using the internal timing controls of the video cassette recorder.
  • stereo components could be turned on immediately and be set to play for a period of one hour. Then, after a desired time has elapsed, a recording device may be turned on and put in the record mode to record a program. At the time of recording, other components may be turned on or placed in a particular position.

  • Fig. 4 shows assembly language code for subroutines usable with the quick touch function in a remote control transmitter.
  • the transmitter unit 10 for a preferred embodiment of the invention, has a display 12, which may, for example, be a liquid crystal display (LCD) and a plurality of input keys.
  • Display 12 is divided into three areas.
  • the primary area 14 displays eight alphanumeric characters in conventional matrix form.
  • alphanumeric characters 14 is printed a plurality of functions and below the alphanumeric display is printed a plurality of device indications.
  • a separate, selectively illuminable light source such as an LCD is positioned under each function indication and under each device indication.
  • controller 10 also has an area 15 containing keys which are normally used to operate a device, which keys are normally accessible, and an area 17, shown in Fig. 1C with respect to the controller of Fig. IB, containing special function keys used for programming controller 10, setting of the clock and timers, and programming keys to perform multiple functions, which area may be normally covered to prevent tampering by children and others.
  • Area 17 is hidden by cover 105 during normal operation of remote controller 10 of Fig. IB.
  • Area 15 has a light 16 which may be a light emitting diode, lamp, or other suitable electrically controlled source of light which is enabled when the system is receiving key codes from a dedicated controller and is illuminated when the I/R transmitter of the source controller is suitably positioned with respect to the I/R receiver of controller 10 so as to permit proper receipt of the transmitted codes.
  • Light 16 will not be on during the reception of codes if the two controllers are too far apart, or are not sufficiently aligned so as to permit accurate receipt of the transmitter I/R codes.
  • Controller 10 has a plurality of keys in areas 15 and 17, some of which may be programmed to perform a desired function and some of which are dedicated to a particular function.
  • the dedicated keys include SELECT keys 18A and 18B, which may be used, as will be described later, to select various devices or functions, CHANNEL keys 20A and 2OB which may be used to step either down or up respectively to select a desired channel, station, or the like for a particular device being controlled and VOLUME CONTROL keys 22A and 22B which may be used to lower or increase the sound volume of a controlled device.
  • the remaining keys having dedicated functions are in area 17 and include a WAIT/TIMER key 24, a CLOCK CONTROL key 26, an ON/OFF key 28, a SET/STORE key 30, a DOWN CURSOR key 32, an UP CURSOR key 34, and INSERT key 36, and a DELETE key 38.
  • Area 17 also includes run/learn switch 40, the setting of which determines whether the controller is operating normally or to receive codes from a dedicated controller.
  • Area 15 also has a plurality of programmable keys each of which may either perform the function printed on the key or may be programmed to perform another function which a user may indicate in the blank space appearing above the key. Above the SELECT keys 18 of Fig.
  • keys 42 and 44 which may function as a MUTE key and a POWER key respectively. However, if desired, these keys may also be programmed to perform other functions in a manner to be described hereinafter.

  • Central processing unit (CPU) 13 is an application specific integrated circuit (ASIC) with a microprocessor core.
  • CPU 13 is used to control the various components of remote controller 10.
  • Display 12 is connected to CPU 13 through a display controller 91.
  • Display 12 is used to display information to a user of remote controller 10.
  • a battery and power supply 19 are used to power CPU 13 in remote controller 10.
  • a user may input instructions to remote controller 10 through a keyboard 21 including keys in areas 15 and 17.
  • a ROM 23 is used to store code which is implemented in CPU
  • RAM 25 is used to store instruction codes learned by remote controller 10 as well as keystroke sequences input by a user on keyboard 21. The codes are compacted in order to minimize storage requirements. Compacted codes are transferred between RAM 25 and CPU 13 over the address bus and the data bus. RAM 25 also stores information relating to programmed code sequences to be performed by controller 10. The learning of various instructions and sequences of instructions from a dedicated controller is found in U.S. Patent No..4,825,200 to Evans, et al., incorporated herein by reference.
  • a clock 27 is a real time clock which can be used to display the time on display 12 as well as for use in keeping track of an amount of time which has elapsed during the recording of a selected duration and for use in commencing and ending a programming session.
  • a control switching unit 29 interfaces keyboard 21 to clock 27 so that the time may be changed as well as interfacing clock 27 to CPU 13 so that elapsed time may be tracked.
  • a transmit circuit 31 is used to transmit infrared signals from CPU 13 to the remotely controllable devices in the system.
  • Learn circuit 33 is used to input infrared signals from a dedicated remote controller so that remote controller 11 can learn the signals for controlling the various devices.
  • Range transmit circuit 35 is used to determine whether the dedicated controller is properly positioned during learning so that CPU 13 can recognize the infrared signals received from the dedicated controller.
  • controller 10 When controller 10 is first powered by, for example, inserting batteries therein, there are no I/R commands stored in RAM 25 and clock 27 has not been set. The user must set clock 27 to the proper time and day in order for clock 27 and the timers in CPU 13 to function properly.
  • the next step in the operation is to store I/R codes in the I/R code storage RAM 25.
  • the first step in this operation is to operate SELECT keys 18A and i ⁇ to cause the annunciator for the device to be learned to be illuminated.
  • the next step in the operation is to set run/learn switch 40 to the learn position.
  • the next step in the operation is to point the I/R transmitter of the source controller, in this case the controller for the TV, at an I/R receiver 120 of controller 10 and to depress the function key on the source controller for the function to be learned.
  • the first function on the TV controller to be learned is the on/off function
  • the user would press the on/off button of the TV controller while holding this controller with its I/R transmitter facing the I/R receiver of controller 10.
  • the user would release the button on the source controller.
  • the user then presses the key in area 15 of controller 10 which is to control the particular function for the particular device.
  • the user might press POWER button 44 on controller 10 at this time.
  • display 12 will show the message BEGIN.
  • the user presses the on/off button on the TV controller to input the I/R code to controller 10.
  • the key should remain depressed until display 12 on controller 10 shows the message STORED. At this time, the key may be released in a normal manner. This sequence of operations may be repeated for each of the keys of the source controller until the codes for all of those keys have been stored.
  • the run/learn switch 40 When all of the codes for a given controller have been stored, the run/learn switch 40 is returned to the run position. Since the received I/R codes have a certain amount of redundancy, CPU 13 compacts these codes before storing them in RAM 25. When one of the codes stored in RAM 25 is to be utilized, CPU 13 deco pacts the stored information to obtain the original I/R code. When all of the codes for a given device have been stored, the process described above may be repeated for the I/R controller of the second device.
  • controller 10 may be utilized to control any one of the devices which it has been programmed to control or may, by use of a program key, be utilized to simultaneously control two or more of the devices.
  • run/learn switch 40 is set to the run position.
  • the first step in using the controller to control a particular device is to operate SELECT keys 18A and/or 18B to illuminate the annunciator corresponding to the selected device.
  • Controller 10 is then held with the I/R transmitter 138 pointed in the general direction of the device to be controller and the key which has been programmed for the desired function on the desired device is operated. This causes the name of the key or function to appear on display 12 and causes the I/R code for the function to be output.
  • a key may be depressed to cause a second function to be performed. For example, one or more of the numbered keys may be depressed to select a channel, or CHANNEL CONTROL keys 20A and/or 20B may be operated to perform this function.
  • Fig. 3 is a flow chart showing the sequence of events which take place as remote controller 11 causes a sequence of instructions to be executed at a desired time.
  • the user causes remote control 11 to enter a quick touch function (QTF) mode 51 by depressing QTF keys 92A, 92B.
  • QTF quick touch function
  • the name of a sequence which will perform various functions is displayed in step 53 on display 12.
  • a fifteen- minute base display time is also displayed in step 55. This time represents a base time unit which can be arbitrarily set to a selected value.
  • a key timer is set in step 57 by depressing wait/timer key 24. This timer will keep track of an interval during which it is determined whether or not a QTF key has been pressed.
  • the delay time continues to be displayed 59 and if a QTF key is pressed again within the selected time interval as show in step 61, then one base time unit (e.g., 15 more minutes) is added to the delay time 63 and the key timer is reset in step 65.
  • the selected duration for recording can be increased in fifteen minute intervals. If a QTF key was not pressed and the selected elapsed time has not expired as shown in step 67 then a return key timer step 57 results. If the selected elapsed time has expired in step 67, then a transmit starting sequence is performed by central processing unit 13. This starting sequence performs various functions. For example, it may turn on the cable box ar.d the television as well as adjust the satellite dish to a particular position. It also turns on the VCR and starts it recording. These functions are executed by central processing unit 13 which retrieves the instructions from ROM 23 and RAM 25 and transmits them through transmit circuit 31.
  • SUBSTITUTESHEET Remote controller 11 then enters an end timer loop which begins with end timer step 71. The time remaining is displayed in step 73 on display 12 as well as the name of the ending sequence (step 75) . In step 77 it is determined from clock 27 whether a particular time unit has expired. If a time unit has expired, one minute,is removed from the remaining time 79 and central processing unit 13 determines whether the delayed- * time is zero in step 81. If the delayed time has not reached zero, remote controller 11 returns to end timer step 71. If it has reached zero, the ending sequence is transmitted in step 83 and remote controller 11 exits the QTF routine (step 85) . Transmission of the ending sequence in step 83 causes a series of instructions to be executed. For example, if it is necessary to turn off a cable box and a TV as well as the VCR, each of these steps will be carried out by remote controller 11. Each of these steps can be programmed into RAM 25 through keyboard 21 during a learning mode.
  • Fig. 4 is an assembly language code listing of the subroutines used in conjunction with the quick touch function in a remote controller.
  • the timer units for key timer time out and the base display time can be altered.
  • the keys on the remote controller could be configured in a variety of layouts.
  • the select key 18A, 18B, the channel keys 20A, 20B and the volume keys 22A, 22B could be single keys instead of two separate keys.
  • more keys may be situated under cover 105 of the controller of Fig. IB.
