[0001] The present invention relates to a display device and a method of operating the same,

The present embodiment relates to an apparatus and a method for controlling a channel or a volume of a display device using a moving position and a moving speed of a remote control unit.

In general, the interactive multimedia center features an increasing amount of functionality provided and an increasing number of channels of available programming. The increased number of available channels resulted from increased program availability from services such as cable and satellite. New types of functions include recording, time-shifting, and convergence with the Internet.

This increase in available programming and functionality makes the user interface more dense and complex in an environment where there is no desktop for a mouse or keyboard, a standard input device for a complex user interface typically represented on a personal computer.

Rather, typical user input devices selected for television and multimedia sensors are one or more infrared remote controls with push buttons including arrows, keypad and dedicated function buttons. The remote control with these buttons selects channels and functions and is used for on-screen navigation. However, interactive televisions and multimedia centers now have too many channels and functions for this type of interface to be effective, requiring a more effective interface.

It is an object of the present invention to provide an apparatus and a method for enabling a user to easily change a channel and a volume of a display device.

A display device according to an embodiment of the present invention includes a control signal receiving unit for receiving a signal transmitted from a remote control unit equipped with a gyro sensor; A controller for reading channel change or volume change information from the signal received through the control signal receiver; And displaying a broadcast program selected through a tuner under the control of the control unit on a display unit, causing a channel change of a broadcast program displayed on the display unit to be performed or displaying an OSD for volume change on the display unit The control unit controls the display unit to sequentially display images of a channel to be changed on the display unit when the channel change signal is received through the control signal receiving unit.

A method of operating a display device according to an exemplary embodiment of the present invention is a method of operating a display device that operates according to a control signal transmitted from a remote control unit having a gyro sensor outputting a signal according to a motion, Obtaining motion information from the transmitted signal; Determining whether the motion information is a channel change signal or a volume change signal; Determining whether the received signal includes motion acceleration information; And if the motion acceleration information is included as a result of the check, the channel change or the volume change is performed differently according to the value of the motion acceleration.

By the apparatus and method as proposed, the user does not have to press the channel change button or the volume change button provided in the remote control unit, and a plurality of keys need not be configured in the remote control unit.

In addition, since the user can determine the number of channels to be changed or the amount of volume to be adjusted through the motion speed of the remote control unit, the user can easily control the channel and the volume.

Hereinafter, the present embodiment will be described in detail with reference to the accompanying drawings. It should be understood, however, that the scope of the inventive concept of the present embodiment can be determined from the matters disclosed in the present embodiment, and the spirit of the present invention possessed by the present embodiment is not limited to the embodiments in which addition, Variations.

In the following description, the word " comprising " does not exclude the presence of other elements or steps than those listed.

1 is a block diagram illustrating a configuration of a remote control unit according to an embodiment of the present invention.

Referring to FIG. 1, the remote control unit of the present invention is an apparatus for remotely controlling a channel or a volume of a display device by the motion of the remote control unit, And an operation for changing the volume of the display device.

The motion detection unit 120 starts as a configuration for tracking the movement of the remote control unit. The motion detection unit 120 includes a gyro sensor (not shown) for outputting an electrical signal corresponding to a positional change of two- or three- And an acceleration sensor 122 for outputting an electric signal corresponding to the acceleration of two or three axes generated from the motion of the unit.

And an arithmetic processing circuit 110 for calculating an electric signal output from each sensor of the motion detecting unit 120. The arithmetic processing circuit 110 is connected to the gyro sensor 121 and the acceleration sensor 122, And calculates the displacement and the speed of the remote control unit body according to the electrical signals continuously output, and outputs the calculated displacement and speed to the MCU 100 as the control processor.

Although the operation processing circuit 110 is shown separately from the MCU 100 in the figure, the operation processing circuit 110 may be embedded in the MCU as a control processor.

The remote control unit may further include a memory 130 in which information on an operating system of the MCU 100 and information on a specific motion of the unit and command codes of the control target device are stored. And a communication module 140 for outputting the command code to a display device or the like, which is a control target device, under the control of the control unit 140. [

The command code output from the communication module 140 may be performed by wire or wireless depending on the connection status of the device to be controlled. In some cases, . ≪ / RTI >

In this case, a signal received from the device to be controlled should be decodable by the MCU 100, and a response signal to the transmitted signal according to the motion of the remote control unit is transmitted through the communication module 140 Lt; / RTI >

The remote control unit may further include an input unit 150 for receiving a command directly from the user and delivering the command to the MCU 100 in addition to the command according to the specific motion of the user detected through the motion detection unit 120 .

The input unit 150 may include an awake button for starting the operation of the motion detection unit 120. If the awake button is separately provided, the user can input the command through the movement of the unit body after inputting the awake button once. . That is, the display device to be controlled can be operated according to the signal of the motion of the remote control unit only when the signal for the awake button is received.

As another configuration, the remote control unit may transmit a motion signal corresponding to the motion of the remote control unit only when the awake button is depressed. In this case, the user may have to move the body of the remote control unit up or down or left or right while pressing the awake button when changing the channel or volume of the display apparatus.

In the case of using the awake button which enables various implementation alterations, the user is less likely to perform unintentional channel change or volume change.

The remote control unit of the embodiment described above will be described in more detail as follows.

The gyro sensor 121 of the motion detection unit 120 is a sensor for measuring a displacement of an object to be moved by measuring an angular velocity as a well known technique, Or left and right movements.

In addition, an acceleration sensor 122 is further provided to measure the acceleration of the remote control unit with respect to the up-and-down movement or the left and right movement, and the acceleration sensor 122 detects the movement speed of the up- The speed can be measured.

The moving direction and the moving speed of the remote control unit with respect to the body motion of the remote control unit are transmitted to the arithmetic processing circuit 110 by the motion detecting unit 120 so that the analog signal output from each sensor is converted into a digital signal, The converted digital signal includes information on the moving direction and the moving speed of the motion.

The present invention relates to a method for adjusting a channel or a volume of a display device using a remote control unit capable of transmitting motion information of a unit body, wherein the gyro sensor and the acceleration sensor enable the user to adjust the degree of channel or volume change .

That is, as the moving speed of the remote control unit in which the user moves increases, the number of channels to be changed can be increased, and the volume can also be largely changed.

The display device receiving the motion signal transmitted from the remote control unit as shown in FIG. 1 decodes the motion direction as well as the motion direction from the received signal, and determines the degree of channel and volume change according to the motion speed .

This will be described with reference to the channel / volume change diagram according to the motion speed schematically shown in FIG.

The up / down of the channel and the up / down of the volume have been performed according to the number of times of inputting the channel key or the volume key provided in the remote control unit. However, in this case, in the case of the unit body measured by the acceleration sensor 122 The degree of change of the channel or the degree of change of the volume is determined based on the movement speed.

2 shows an operation performed in a display device which is an object to be remotely controlled by the remote control unit of FIG. 1, in which, when the movement speed of the remote control unit belongs to the first step, Once.

For example, when the channel of the broadcast program received through the display device is in the order of 6th, 7th, 9th, 11th, and 13th and the currently viewed channel is the seventh channel, When the speed is detected, the channel is also changed to the 9th or 6th channel by performing the first step.

On the other hand, when the moving speed of the remote control unit detected by the display device is the second step or the third step, the channel change is also performed in two or three steps. In this case, .

As a result, the channel and volume change of the display device according to the specific motion of the remote control unit is determined according to the motion speed of the remote control unit, and the degree of change of the channel and volume according to the motion speed is directly set by the user .

For example, the user can set one channel to be up or down in the case of the speed of the first step, and change it to the previous channel in the second or third step. Such setting contents should be stored in the display device.

Meanwhile, various embodiments in which the user operates the remote control unit according to the present invention are shown in Fig.

FIG. 3 shows an example of the motion of the remote control unit according to the embodiment of the present invention, and the function of the illustrated motion is not limited.

There are shown three cases where the user moves the remote control unit body to the right as motion for executing the channel up, the first arrow 310a represents one channel up, the second arrow 310b represents two channel ups, A third arrow 310c represents three channel up.

And, the motion for executing the channel down can be executed by the left movement of the remote control unit, and is similar to the case of the channel up.

On the other hand, in the drawing, the user's hand is shown depressing a button of a certain function (for example, an awake button). According to the embodiment, only when the awake button is pressed, The display device can be operated according to the received motion signal.

Also shown in the figure are the up / down motion of the volume, the arrows shown at 320a represent one level up of the volume, the arrows at 320b represent volume two step up, Up. Turning the volume down can be done by moving the remote control unit down as opposed to the motion to raise the volume.

In FIG. 3, the motion for performing the channel change is shown as the rightward and leftward movement, and the motion for performing the volume change is shown as the upward and downward movement. However, the motion for the channel change and the motion for the volume change, Or alternatively.

A display device to be controlled by the remote control unit will be described in detail.

The display apparatus according to the embodiment of the present invention receives an RF signal transmitted from the remote control unit and performs channel change and volume change according to the contents of the information included in the received RF signal. However, regarding the channel change, the case where one tuner for receiving a broadcast signal is provided to the display device and the case where two tuners are provided will be described separately.

4 is a view illustrating a display device having two tuners according to an embodiment of the present invention.

First, a display device having two tuners will be described with reference to FIG. 4, and a channel changing operation in a case where one tuner is provided will be described.

As shown in the figure, the display apparatus according to the present embodiment includes a first tuner 410 and a second tuner 411 as a tuner unit for tuning and outputting a broadcast signal, and demodulates the selected channel through the tuner unit A demultiplexer (demux) 430 for demultiplexing the demultiplexed signal into demodulated audio, video, DVB-SI and PSIP tables, a decoder for decoding the demultiplexed signal, And a display unit 450 output from the video signal processing unit 440. The display unit 450 includes a display unit 450 and a display unit 450. The display unit 450 includes a display unit 450,

A control signal receiving unit 480 for receiving a signal transmitted from the remote control unit and a control unit 480 for controlling the channel change or the volume change according to the contents included in the information of the signal received through the control signal receiving unit 480 And a control unit 490.

The memory unit 460 is connected to the control unit 490. The memory unit 460 receives the broadcast signal received through the first tuner 410 or the second tuner 420, Can be stored.

A configuration in which a captured image of a received broadcast signal is stored in the memory unit 460 and a stored captured image is used for channel conversion will be useful when a single tuner is provided in the display device and will be described later .

First, when the control unit 490 of the display device determines that up / down information of the channel is included in the signal received through the control signal receiving unit 480, the control unit 490 transmits the next channel (the target channel to be changed) Is displayed while being slid.

That is, the next channel is displayed while being slid to the full screen on the partial screen, and the current channel gradually slides and disappears.

This is exemplarily shown in Figs. 5 to 7. Fig.

When the user inputs a specific motion of the remote control unit and the motion is a signal instructing the channel up, the display device receiving the signal is sliding the right channel to the right, Is displayed while being slid. This case is shown in Fig.

For example, when the specific motion of the remote control unit is a rightward movement, this indicates channel up, and the current channel displayed through the display unit disappears while moving rightward, and at the same time, the image of the next channel is gradually enlarged from the left to the whole screen.

On the contrary, when the down command of the channel is the leftward movement of the remote control unit, the current channel is slid to the left, and the previous channel (the channel to be downed) is gradually slid from the right and enlarged to the entire screen have.

Meanwhile, the remote control unit may further include an acceleration sensor, so that up / down of a channel can be performed for a plurality of channels. That is, if the channel up information of the second stage in the example shown in FIG. 2 is transmitted from the remote control unit, the display device receiving the channel up information performs an operation of uplinking two channels by the method as shown in FIG. 5 or 6 Can be performed. For example, as the currently viewed 9th channel is slid and disappears, the 11th channel appears as a sliding mode, and the 11th channel also disappears as a sliding mode, and the 13th channel, which is the next channel, is displayed as a sliding mode.

Although the current channel and the next channel are described as being changed by the sliding method, it is also possible to arrange that the current channel gradually disappears while being transparently displayed according to the degrading method, and the next channel gradually appears as having a shadow Reference).

In FIG. 7, a current channel is positioned as a still image or a moving image, and the next channel is slid as it becomes gradually clear to an image having a predetermined transparency.

Even if the embodiment of the present invention is changed, it is necessary to explain the process of processing the broadcast signal for the current channel and the broadcast signal for the next channel since the present channel and the next channel are displayed together on the display unit 460 .

Here, the process may be different depending on whether one or two tuners are provided in the display device.

4, when the current channel is a broadcast signal tuned through the first tuner 410, the control unit 490 controls the first tuner 410 in the channel change process, 410 and tunes and tunes the next channel's broadcast signal through the second tuner 411. [

The control unit 490 controls the video signal processor 440 to gradually disappear the channel selected through the first tuner 410 so as to disappear from the screen and the channel selected through the second tuner 411 So as to gradually appear on the screen.

In the case where only one tuner is provided unlike the case of the drawing, when a channel change signal is input, an image of a broadcast signal for the current channel is captured and stored in the memory unit 460, Tune in the channel. Then, the image captured in the memory unit 460 disappears while sliding on the screen, and the broadcast signal of the next channel selected through the tuner is displayed while sliding on the screen.

That is, the user can observe that the captured still image gradually disappears with respect to the current channel, and the broadcast signal of the next channel appears as a moving image.

As a result, when the channel change signal is input, the controller 490 displays the current channel as a captured still image or a moving image being received according to the number of tuners.

The operation of performing volume control of the display device using the remote control unit having the gyro sensor and / or the acceleration sensor will be described with reference to FIGS. 8 and 9 attached hereto.

FIG. 8 and FIG. 9 are views showing that the volume of a display device is adjusted by a specific motion of a remote control unit according to an embodiment of the present invention.

8 and 9 show a display device such as a DTV. However, it is also possible to adjust the volume of an audio device and adjust the volume of an external device connected to the display device according to a modification of the embodiment. Also, It is within the scope of thought.

Information on the motion is output from the remote control unit by up-and-down movement or left-and-right movement of the remote control unit, and the display device to be controlled by the remote control unit receives the corresponding signal, Is performed.

Here, the video signal processing unit 440 of the display device may generate an OSD for controlling the volume on the screen, and the OSD generating unit may be provided in the video signal processing unit 440, but an OSD generating unit may be further formed as a separate component .

As a user interface for changing the volume, a bar-shaped volume control level may be displayed as in the case of FIG. 8, or a plurality of bar levels may be displayed differently according to the volume size as in FIG. 9 .

As described above, when the motion speed measured by the acceleration sensor of the remote control unit is outputted to the display device, the degree of the up or down of the volume can be determined according to the speed of the motion.

For example, when the motion speed of the remote control unit is measured in the second step as in the case of FIG. 2, the volume of the display device is increased to a level corresponding to the two-level level. The volume can be upgraded.

If the acceleration sensor is not provided in the remote control unit, the body of the remote control unit may be moved upward or rightward twice in order to raise the volume 2 chamber.

10 is a flowchart illustrating an operation method of a display apparatus according to an embodiment of the present invention.

First, the remote control unit for remotely controlling the operation of the display device is provided with a gyro sensor capable of measuring the direction of movement of the body, and further includes an acceleration sensor capable of measuring the acceleration of the motion .

The receiving unit of the display device receives the wired / wireless signal transmitted from the remote control unit (S901), and the control unit of the display device determines whether the information of the received signal is a signal for channel change (S902).

If the received signal is a signal for channel change, the control unit of the display device further checks whether the information indicating the motion speed or the acceleration of the remote control unit is included (S903) If so, the channel change corresponding to the acceleration level is performed (S904).

Here, the channel change corresponding to the acceleration level means that the number of channel changes is determined according to the magnitude of the measured acceleration as described above. An example of changing one channel or two channels or three channels for three levels of levels has been described.

On the other hand, if it is determined in step S903 that the acceleration information is not included in the signal received in the display device, the channel is changed for the motion content (S905). If the motion information is upward or rightward motion, The channel is up, and when it is the downward or leftward motion, one channel is down. As in the case of Fig. 3, even when the movement from the upper side or the left side to the right side is inputted a plurality of times, a plurality of channel changes will be performed.

Such a channel change is indicated by a sliding method, and the user will see that the next channel pushes the current channel. Also, when the channel change is performed in the degrade scheme, the next channel will appear to the user to be gradually and clearly displayed on the current channel screen.

On the other hand, if it is determined in step S902 that the received signal is not a signal for channel change, the control unit of the display device determines whether the signal is a signal for volume change (S906). If the received signal is a signal for volume change It is checked whether acceleration information is included in the signal (S903).

In this case, the volume change corresponding to the acceleration level is also performed (S904), or the one-step change of the volume with respect to the motion content is performed (S905).

If it is determined in step S906 that the received signal is not a signal for changing the volume, the controller of the display device controls the controller to perform a corresponding operation according to the key input because it is a signal according to a general remote controller key input (S907) .

By this method, the user can easily change the channel or volume by applying a specific motion to the remote control unit.
