Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a divisional of U.S. patent application
Ser. No. 10/283,641, filed Oct. 30, 2002, entitled "Universal
Remote Control Unit" which is a divisional of U.S. patent
application Ser. No. 09/419,605, filed Oct. 18, 1999, entitled
"Universal Remote Control Unit," the entire subject matter of these
applications being incorporated herein by reference.
TECHNICAL FIELD
[0002] The present invention relates generally to remote control
units, and more particularly, to remote control units for remotely
controlling a plurality of devices.
BACKGROUND INFORMATION
[0003] Remote control units have gained widespread popularity for
use in remotely controlling home entertainment systems, which
typically include several devices such as a television set, a cable
box or converter, a videocassette recorder, and a stereo. Often,
with each device, the manufacturer will supply a remote control
unit for use in remotely controlling that device.
[0004] A universal remote control unit provides a single unit
having a plurality of operating modes for controlling a plurality
of devices. Each operating mode allows a user to remotely control a
respective one of the devices. Typically, a universal remote
control unit includes a plurality of mode push buttons, e.g.,
CABLE, TV, and VCR push buttons, which correspond to the different
devices to be controlled and which are used to directly change the
operating mode of the universal remote control unit.
[0005] Changing operating modes of the universal remote control is
often accomplished by simply pressing the appropriate mode push
button, i.e., CABLE, TV or VCR push button. For example, with the
universal remote control unit in the cable mode, to turn on the
cable box, a user presses a POWER push button. Next, if the user
wants to turn on the television set, the user must first press the
TV push button then the POWER push button. Thereafter, in order to
operate the cable box again, the user must then press the CABLE
push button before selecting, for example, the channel up or down
push buttons on the universal remote control unit. Later, if the
user wishes to turn off the television and the cable box, the user
must press the CABLE push button, the POWER push button, the TV
push button, and then the POWER push button.
[0006] A drawback with this type of universal remote control unit
is that it is easy for a user to unintentionally change the
operating mode of the universal remote control unit by
inadvertently pressing the CABLE, TV or VCR push buttons. Another
drawback is that the operation of the universal remote control is
often confusing, particularly when a user first turns on several
devices and desires to control one of the devices without first
placing the universal remote control back in the proper operating
mode to control that device. A further drawback is that numerous
button presses are typically required to turn on/off multiple
devices.
[0007] Other universal remote control units have included a single
mode push button instead of separate push buttons corresponding to
each of the devices. By pressing the mode push button, the
operating mode of the universal remote control unit changes, i.e.,
cycles, from one operating mode to the next.
[0008] A drawback with this type of universal remote control unit
is that it is often necessary to press the mode push button a
number of times in order to change from one operating mode to
another. Another drawback with this type of universal remote
control unit is that it is also easy for a user to unintentionally
change the operating mode of the universal remote control unit by
inadvertently pressing the mode push button.
SUMMARY OF THE INVENTION
[0009] Therefore, there is a need for a universal remote control
unit, which reduces the likelihood of the user unintentionally
changing the operating mode of the universal remote control unit.
In addition, desirably the universal remote control unit allows the
user to readily determine the current operating mode, turn on/off
the devices with fewer button presses, and may be user programmable
to simplify the operation of the universal remote control unit.

that the at least one key is operable upon activation to transmit
transmissions to effect the additional function in at least one of
the plurality of different devices, and activating the at least one
key with a single activation of the at least one key to transmit
transmissions to effect the default function in the at least one of
the plurality of different devices and to transmit transmissions to
effect the additional function in at least one of the plurality of
different devices.
[0011] The present invention provides, in a second aspect, a method
for remotely controlling a plurality of different devices. The
method includes obtaining a universal remote control unit having a
set-up routine for matching it to the plurality of different
devices and having at least one function means having a default

transmit transmissions to effect the default function in at least
one of the plurality of different devices, assigning, in addition
to the default function, an additional function to the at least one
function means so that the at least one function means is operable
upon activation to transmit transmissions to effect the additional
function in at least one of the plurality of different devices, and
activating the at least one function means with a single activation
of the at least one function means to transmit transmissions to
effect the default function in the at least one of the plurality of
different devices and to transmit transmissions to effect the
additional function in at least one of the plurality of different
devices.
[0012] The present invention provides, in a third aspect, a

DETAILED DESCRIPTION OF THE INVENTION
[0020] FIG. 1 illustrates an exemplary universal remote control
unit 10 of the present invention for controlling a plurality of
devices 20. As will be explained in greater detail below, universal
remote control unit 10 is configured to be effective to reduce the
likelihood of unintentionally changing the operating mode of
universal remote control unit 10. In addition, universal remote
control unit 10 readily allows a user to determine the current
operating mode of remote control unit 10. Furthermore, universal
remote control unit 10 may include individual mode buttons for each
device that turn on/off each device and which mode buttons may be
user-programmable to simplify operating universal remote control
unit 10.
[0021] Examples of the plurality of devices 20 which may be
controlled by universal remote control unit 10 include a cable box
or converter 22, a television set 24, a video device 26 such as a
videocassette recorder, a digital video disk (DVD) player, or a
laser-disk (LD) player, and an audio device 28 such as an
amplifier, a digital music converter, or an audio-video
receiver.
[0022] With reference to FIG. 1, universal remote control unit 10
includes input means 12 (FIG. 2) which may include function means
or a keyboard 30 for enabling a user to select a plurality of
functions in connection with the operation of the plurality of
devices 20. As best shown in FIG. 1, keyboard 30 may include a
CHANNEL push button 31, a VOLUME push button 34, a plurality of
numbered push buttons 36, a plurality of video function push
buttons 38, etc.
[0023] In addition, as explained in greater detail below, input
means 12 (FIG. 2) also includes a first mode means or DEVICE push
button 40 for initiating a mode change, and a plurality of second
mode means or mode push buttons 50 such as a CABLE push button 52,
a TV push button 54, a VIDEO push button 56, and an AUDIO push
button 58 for placing universal remote control unit 10 in a
respective one of a plurality of operating modes. For example,
universal remote control unit 10 in its cable mode operates the
functions of the cable box 22. In its television mode, universal
remote control unit 10 operates the functions of television set 24.
Desirably, as explained below, each of the plurality of mode push
buttons may be illuminatable, having, for example, a backlit
light-emitting diode.
[0024] With reference to FIG. 2, universal remote control unit 10
includes, in addition to input means 12, a processor 60 having a
plurality of operating modes each of which corresponds to a
different one of the plurality of devices 20 (FIG. 1), a memory 70,
and a transmitter 80. Activation of one of the plurality of push
buttons of keyboard 30 (FIG. 1) by a user generates a command
signal when depressed. This command is supplied to processor 60. In
response thereto, processor 60 retrieves an appropriate control
code from a memory 70, as is well known in the art. Processor 60
then causes transmitter 80 such as an infrared transmitter to
generate pulses in accordance with the control code, which are
received by one of the plurality of devices 20 (FIG. 1) thereby
causing one of the controlled devices, e.g., cable box 22,
television 24, video device 26, or audio device 28, to carry out
the command function.
[0025] Processor 60 may include a programmable infrared (IR)
low-voltage microcontroller device. Examples of such a device
include a Z8 MCU single-chip device from Zilog, Inc., and a
GMS344XXXT series device from LG (Goldstar) Semicon Co., Ltd. The
processor is run by application software or programming, e.g.,
assembly language, and is typically governed by the manufacturer's
protocol. The devices can be of single package design or multiple
package design with external or additional memory storage from the
processor.
[0026] The invention is not limited to such a processing
environment, however. The present invention can be incorporated and
be used within many types of processing environments. From the
following description, computer readable program code means for use
in processor 60 and for implementing the present invention may be
readily programmed by those skilled in the art and stored in memory
70 such as memory chip or an integrated circuit.
[0027] FIG. 3 is a flowchart of an exemplary process of the
invention operating universal remote control unit 10. As discussed
in greater detail below, identifying the current operation mode and
changing the operating modes of universal remote control unit 10
are accomplished through use of DEVICE push button 40.
Identifying Current Operating Mode
[0028] With reference still to FIG. 3, if a user does not know
which is the current operating mode of universal remote control
unit 10, processor 60 (FIG. 2) may be programmed so that the user
at 100 can press DEVICE push button 40 (FIG. 1) which causes one of
mode push buttons 50 (FIG. 1) to illuminate which corresponds to
the current mode of operation of universal remote control unit 10
at 102. For example, if the current mode is the television
operating mode, TV push button 54 remains illuminated, as
illustrated in FIG. 1, desirably for a predetermined amount of
time. The predetermined amount of time may be from about five
seconds to about ten seconds.
[0029] With reference again to FIG. 1, if the identified current
operating mode after activating DEVICE push button 40 is the
operating mode desired by the user, the user may then activate the
other push buttons, e.g. function push buttons, of keyboard 30 to
control that device. For example, if the current mode is the
television mode, CHANNEL push button 31 can be activated for
increasing/decreasing the channels of television set 24, or VOLUME
push button 34 can be activated for increasing/decreasing the
volume of television set 24.
Changing Operating Modes
[0030] With reference to again FIG. 3, processor 60 (FIG. 2) may be
programmed so that changing the operating mode of universal remote
control unit 10 comprises pressing DEVICE push button 40 (FIG. 1),
for example, at 100, pressing one of mode push buttons 50 (FIG. 1)
at 104, and determining whether the mode push button was pressed
within a predetermined amount of time at 106. If one of the mode
push buttons 50 is selected within the predetermined amount of
time, at 108 the operating mode is set and/or changed to the
activated mode push button. This predetermined amount of time may
be from about five to about ten seconds, and desirably corresponds
to the current operating amount of time for illuminating the mode
push button corresponding to the current operating mode.
[0031] With reference again to FIG. 1, for example, after pressing
DEVICE push button 40, and while the mode push button corresponding
to the current operating mode is illuminated, e.g., TV push button
54, the user can select a different device to operate by pressing
one of the other non-illuminated mode push buttons 50, e.g., CABLE
push button 52, VIDEO push button 56, or AUDIO push button 58.
Desirably, when a non-illuminated mode push button 50 is selected,
the mode push button illuminates, for example, blinks and then goes
out, at 108 (FIG. 3).
[0032] By requiring a user to activate two push buttons and also
activate the two push buttons within a predetermined time, the
likelihood of a user unintentionally changing the operating mode of
universal remote control unit 10 is reduced.
Turning On/Off the Devices
[0033] Mode push buttons 50 may also be used and processor 60
suitably programmed so that activation of each mode push buttons 50
turns on/off a corresponding one of devices 20. This is
accomplished by not pressing device button 40 and only pressing one
of mode push buttons 50, e.g., CABLE push button 52, TV push button
54, VIDEO push button 56, and AUDIO push button 58. For example, if
a mode push button is not pressed within the predetermined time of
pressing DEVICE push button 40, the current operating mode is not
changed at 107 (FIG. 3), and the activated mode push button 50
toggles that device on/off at 109 (FIG. 3). Activating any of the
mode push buttons 50 thereafter toggles the corresponding device
on/off.
Programmable Mode Push Buttons
[0034] Universal remote control unit 10 may also include
user-programmable mode push buttons 50 that can be programmed, for
example with up to eight functions in addition to its normal
function (e.g., power on/off toggle) to transmit a plurality of
functions that simplify the operation of universal remote control
unit 10 and desirably reduce the number of push button presses.
Desirably, keyboard 30 includes a programming push button or OK/SEL
push button 45 for use in programming processor 60 as described
below.
Programmable TV Push Button
[0035] As discussed above, TV push button 54 and DEVICE push button
40 may be used to identify and/or change the operating mode of
universal remote control unit 10, as well as turn on and off
television set 24.
[0036] Desirably, TV push button 54 may also be user-programmable
to transmit a plurality of functions in addition to its normal
(television power on/off toggle) function. For example, the user
can program processor 60 so that TV push button 54 turns on (or
off) television set 24 and tunes television set 24 to any desired
channel (typically channel 3) with one push button press.
[0037] For example, processor 60 may be programmed to allow TV push
button 54 to be programmed as follows. With universal remote
control unit 10 in the television mode, TV push button 54 and
OK/SEL push button 45 are pressed at the same time and held down
until TV push button 54 illuminates indicating that processor 60 is
ready to receive a plurality of push button presses. With TV push
button 54 illuminated, TV push button 54, numerical push button
"0," and numerical push button "3" are pressed in order. To store
the desired push button presses in processor 60, an end-programming
push button or CHANNEL UP push button 32 is pressed. Thereafter,
when TV push button 54 is pressed, universal remote control unit 10
performs the above-noted actions for controlling television set
24.
Programmable CABLE Push Button
[0038] As discussed above, CABLE push button 52 and DEVICE push
button 40 may be used to identify and/or change the operating mode
of universal remote control unit 10, as well as turn on and off
cable box 22.
[0039] Desirably, CABLE push button 52 may also be
user-programmable to transmit a plurality of functions in addition
to its normal (cable power on/off toggle) function. For example,
the user can program processor 60 so that CABLE push button 52
turns on cable box 22 and television set 24 with one push button
press.
[0040] For example, processor 60 may be programmed to allow CABLE
push button 52 to be programmed as follows. With universal remote
control unit 10 in the cable mode, CABLE push button 52 and OK/SEL
push button 45 are pressed at the same time and held down until
CABLE push button 52 illuminates indicating that processor 60 is
ready to receive a plurality of push button presses. With CABLE
push button 52 illuminated, CABLE push button 52, TV push button 54
are pressed in order. To store the desired push button presses in
processor 60, an end-programming push button CHANNEL UP push button
32 is pressed. Thereafter, when CABLE push button 52 is pressed,
universal remote control unit 10 performs the above-noted actions
for controlling cable box 22 and television set 24.
Programmable BYPASS Push Button
[0041] Universal remote control unit 10 may also desirably include
a BYPASS push button 47, the activation of which results in
transmission of a command for activating/deactivating the bypass
mode of cable box 22. Typically, the bypass mode on cable box 22 is
designed to allow the user to record one program through cable box
22 via video device 26 while watching a different program on
television set 24. A common problem is that users forget to re-tune
their television to channel 3 (or 4) when exiting the cable box`
bypass mode which results in no picture or a snowy picture at
best.
[0042] Desirably, BYPASS push button 47 may also be
user-programmable to transmit a plurality of functions in addition
to its normal (cable bypass on/off toggle) function.
Advantageously, BYPASS push button 47 can be programmed so that any
time it is pressed, it will also tune television set 24 to a
specific channel, e.g., channel 3 (or 4). This is desirable because
when exiting the bypass mode of cable box 22, television 24 should
be re-tuned to its default channel, typically channel 3 (or 4), for
proper cable reception.
[0043] Processor 60 may be programmed to allow BYPASS push button
47 to be programmed as follows. With universal remote control unit
10 in the cable mode, BYPASS push button 47 and OK/SEL push button
45 are pressed at the same time and held down until CABLE push
button 52 illuminates indicating that processor 60 is ready to
receive and store a plurality of push button presses. With CABLE
push button 52 illuminated, DEVICE push button 40, TV push button
54, numerical push button "0," and numerical push button "3," are
pressed in order. To store the desired push button presses in
processor 60, an end-programming push button or CHANNEL UP push
button 32 is pressed. Thereafter, pressing BYPASS push button 47,
universal remote control unit 10 performs the above-noted actions
for controlling cable box 22 and television set 24.
[0044] To return TV push button 54, CABLE push button 52, BYPASS
push button 47 to their normal default settings, programming for
each push button is initiated, and the CHANNEL DOWN push button 33
is pressed.
VCR/VOD
[0045] Cable box 22 may also include "video-on-demand" capability,
which allows a viewer the ability to watch a movie. When a
video-on-demand movie is ordered, it is downloaded into the memory
of cable box 22 where the viewer can watch it similar to a rented
movie on tape, e.g., using the VCR push buttons on a remote control
unit to control various functions, e.g., play, stop, rewind,
etc.
[0046] Universal remote control unit 10 may further comprise a
VCR/VOD push button 49 and processor 60 programmed to allow the
plurality of video function push buttons 38 to be used for
activating control of video device 26, or for controlling the
viewing a video-on-demand movie stored in cable box 22. From the
present description, it will be appreciated that VCR/VOD push
button 49 and processor 60 eliminates changing operating modes of
universal remote control unit 10 between the cable mode and video
mode.
[0047] For example, pressing VCR/VOD push button 49, the current
mode (function) of the plurality of video function push buttons 38
may be indicated by illumination of either VIDEO push button 56 or
CABLE push button 52. While the current mode, either the VIDEO push
button or CABLE push button is illuminated, within a predetermine
amount of time, pressing VCR/VOD push button 49 again switches the
function of the video function push buttons 38 to the other,
non-illuminated, mode. Desirably, when the operating mode (cable or
video device) of the video function push buttons 38 is changed, the
new mode push button (CABLE push button or VIDEO push button)
blinks and goes out.
Preprogrammed ALL Push Button
[0048] Universal remote control unit 10 may also include an ALL
push button 48, which turns on/off all of the devices upon one
button press. Desirably, once a user sets up universal remote
control unit to operate the various devices, processor 60 is
desirably programmed so that activation of ALL push button 48 turns
on/off the power to each of the devices.
[0049] Advantageously, from the present description, remote control
unit 10 overcomes a number of major operational problems that users
of prior art universal remote control units encounter. For one,
universal remote control unit 10 makes it more difficult for users
to unintentionally change operating modes of remote control unit
10. This is accomplished by requiring the user to first press a
DEVICE push button, followed by the mode push button for the device
to be operated within a predetermined amount of time. Second,
remote control unit 10 reduces the number of push button presses
required to turn on/off a plurality of devices by making each mode
push button operate as a power on/off for its device. Third, the
illuminated mode push buttons readily allow identification of the
device being operated. Fourth, the VCR/VOD push button allows
switching the function of the video function push buttons between
the cable box and the video device. Fifth, making the various mode
push buttons user-programmable further reduces the number of push
button presses necessary for remotely controlling a plurality of
devices.
[0050] From the present description, it will be appreciated by
those skilled in the art that a suitable display, e.g., liquid
crystal display having a touch screen, may be used instead of the
push buttons for allowing a user to select an operating mode and/or
a function for remote control of the devices. In addition, it will
be appreciated by those skilled in the art that instead of
illuminatable push buttons, one or more light-emitting diodes may
be disposed on universal remote control unit to indicate the
current operating mode, indicate a change in the operating mode,
etc. Further, it will be appreciated that instead of a cable mode
button, a digital satellite system receiver button may be provided
for controlling such a receiver.
[0051] Thus, while various embodiments of the present invention
have been illustrated and described, it will be appreciated to
those skilled in the art that many changes and modifications may be
made thereunto without departing from the spirit and scope of the
invention.
