The control unit 170Q of the broadcast signal receiver 100Q according to the present invention includes a demultiplexer 310Q, an image processor 320Q, an OSD generator 340Q, a mixer 350Q, a frame rate converter 355Q, And formatter 360Q. In addition, the apparatus may further include a voice processor (not shown) and a data processor (not shown).

The demultiplexer 310Q demultiplexes the input stream. For example, when an MPEG-2 TS is input, it may be demultiplexed and separated into video, audio, and data signals, respectively. Here, the stream signal input to the demultiplexer 310Q may be a stream signal output from the tuner 110Q, the demodulator 120Q, or the external device interface unit 135Q.

The image processor 320Q may perform image processing of the demultiplexed image signal. To this end, the image processor 320Q may include an image decoder 325Q and a scaler 335Q.

The video decoder 325Q decodes the demultiplexed video signal, and the scaler 335Q performs scaling to output the resolution of the decoded video signal on the display unit 180Q.

The video decoder 325Q may include decoders of various standards.

For example, when the demultiplexed video signal is an encoded video signal of MPEG-2 standard, it may be decoded by an MPEG-2 decoder.

Also, for example, when the demultiplexed video signal is a digital video broadcasting (DMB) scheme or an encoded video signal of H.264 standard according to DVB-H, it may be decoded by an H.264 decoder.

On the other hand, the video signal decoded by the image processor 320Q is input to the mixer 350Q.

The OSD generator 340Q generates an OSD signal according to a user input or itself. For example, based on a control signal from the user input interface unit 150Q, a signal for displaying various types of information on a screen of the display unit 180Q as a graphic or text may be generated. The generated OSD signal may include various data such as a user interface screen, various menu screens, widgets, and icons of the broadcast signal receiver 100Q.

For example, the OSD generator 340Q may generate a signal for displaying broadcast information based on subtitles or EPGs of a broadcast video.

The mixer 350Q may mix the OSD signal generated by the OSD generator 340Q and the decoded image signal processed by the image processor 220Q. The mixed signal is provided to the formatter 360Q. Since the decoded broadcast video signal or the external input signal and the OSD signal are mixed, the OSD can be overlaid on the broadcast image or the external input image.

The frame rate converter (FRC) 355Q may convert a frame rate of an input video. For example, a 60Hz frame rate is converted to 120Hz or 240Hz. When converting a frame rate of 60 Hz to 120 Hz, it is possible to insert the same first frame or insert a third frame predicted from the first frame and the second frame between the first frame and the second frame. When converting a frame rate of 60 Hz to 240 Hz, it is possible to insert three more identical frames or three predicted frames. On the other hand, it is also possible to maintain the input frame rate without additional conversion.

The formatter 360Q receives the output signal of the frame rate converter 355Q, changes the format of the signal to be suitable for the display unit 180Q, and outputs the signal. For example, the R, G, B data signals may be output, and the R, G, B data signals may be output as low voltage differential signaling (LVDS) or mini-LVDS.

5 is a view for explaining a control method of the wireless input unit. In the following, the description of the parts described above in detail will be omitted.

As illustrated in FIG. 5A, a pointer 205Q corresponding to the wireless input unit 200Q is displayed on the display unit 180Q. Here, the pointer 205Q may be a cursor.

The user may move or rotate the wireless input unit 200Q up and down, left and right (Fig. 5 (b)), front and rear (Fig. 5 (c)).

In this case, the pointer 205Q displayed on the display unit 180Q of the broadcast signal receiver may correspond to the movement of the wireless input unit 200Q.

The wireless input unit 200Q may be referred to as a spatial remote controller because the pointer 205Q is moved and displayed as the 3D space moves.

FIG. 5B illustrates that when the user moves the wireless input unit 200Q to the left side, the pointer 205Q displayed on the display unit 180Q of the broadcast signal receiver also moves to the left side correspondingly.

Information about the movement of the wireless input unit 200Q sensed by the sensor of the wireless input unit 200Q is transmitted to the control unit 170Q of the broadcast signal receiver 100Q.

 The controller 170Q may calculate the coordinates of the pointer 205Q from the information about the movement of the wireless input unit 200Q. In addition, the display unit 180Q of the broadcast signal receiver 100Q may display the pointer 205Q so as to correspond to the calculated coordinates.

FIG. 5C illustrates a case in which the user moves the wireless input unit 200Q away from the display unit 180Q while pressing a specific button in the wireless input unit 200Q. In this case, the selection area in the display unit 180Q corresponding to the pointer 205Q may be zoomed in to be enlarged and displayed.

On the contrary, when the user moves the wireless input unit 200Q closer to the display unit 180Q, the selection area in the display unit 180Q corresponding to the pointer 205Q may be zoomed out to be reduced in size. .

Meanwhile, when the wireless input unit 200Q moves away from the display unit 180Q, the selection area may be zoomed out, and when the wireless input unit 200Q approaches the display unit 180Q, the selection area may be zoomed in.

On the other hand, while pressing a specific button in the wireless input unit 200Q, the recognition of the vertical movement can be excluded. That is, when the wireless input unit 200Q moves away from or approaches the display unit 180Q, the up, down, left, and right movements may not be recognized, and only the front and back movements may be recognized. In a state where a specific button in the wireless input unit 200Q is not pressed, only the pointer 205Q is moved in accordance with the up, down, left, and right movements of the wireless input unit 200Q.

Meanwhile, the moving speed or the moving direction of the pointer 205Q may correspond to the moving speed or the moving direction of the wireless input unit 200Q.

The pointer 205Q may refer to an object displayed on the display unit 180Q in response to the operation of the wireless input unit 200Q. Accordingly, objects of various shapes are possible with the pointer 205Q in addition to the arrow shapes shown in the drawing. For example, the concept may include a point, a cursor, a prompt, a thick outline, and the like. In addition, the pointer 205Q may be displayed corresponding to any one of the horizontal axis and the vertical axis of the display unit 180Q, and may be displayed corresponding to a plurality of points such as a line and a surface. .

6 is a view for explaining the configuration of the wireless input unit. Hereinafter, the description of the parts described in detail above will be omitted.

Referring to FIG. 6, the wireless input unit 200Q includes a wireless communication unit 225Q, a user input unit 235Q, a sensor unit 240Q, an output unit 250Q, a power supply unit 260Q, a storage unit 270Q, and a controller 280Q. ) May be included.

The wireless communication unit 225Q may communicate with any one of the control unit 170Q of the broadcast signal receiver according to the embodiments of the present invention described above.

For example, the wireless input unit 200Q may include an RF module 221Q capable of transmitting and receiving signals to and from the control unit 170Q via the user input interface unit 150Q of the broadcast signal receiver 100Q according to the RF communication standard. have. In addition, the wireless input unit 200Q may include an IR module 223Q capable of transmitting and receiving signals according to IR communication standards.

Here, the wireless input unit 200Q may transmit a signal containing information about the movement of the wireless input unit 200Q to the control unit 170Q of the broadcast signal receiver 100Q through the RF module 221Q.

In addition, the wireless input unit 200Q may receive a signal transmitted from the control unit 170Q of the broadcast signal receiver 100Q through the RF module 221Q. In addition, the wireless input unit 200Q may transmit a command regarding power on / off, channel change, volume change, etc. to the controller 170Q of the broadcast signal receiver 100Q through the IR module 223Q as necessary.

The user input unit 235Q may be configured as a keypad, a button, a touch pad, or a touch screen. The user may input a command related to the broadcast signal receiver 100Q to the wireless input unit 200Q by manipulating the user input unit 235Q.

When the user input unit 235Q includes a hard key button, the user may input a command related to the broadcast signal receiver 100Q to the wireless input unit 200Q through a push operation of the hard key button.

When the user input unit 235Q includes a touch screen, the user may input a command related to the broadcast signal receiver 100Q to the wireless input unit 200Q by touching a soft key of the touch screen.

In addition, the user input unit 235Q may include various kinds of input means that a user can operate, such as a scroll key or a jog key, and the present embodiment does not limit the scope of the present invention.

The sensor unit 240Q may include a gyro sensor 241Q or an acceleration sensor 243Q.

The gyro sensor 241Q may sense information about the movement of the wireless input unit 200Q.

For example, the gyro sensor 241Q may sense information about an operation of the wireless input unit 200Q based on the x, y, and z axes. The acceleration sensor 243Q may sense information about a moving speed of the wireless input unit 200Q. On the other hand, the distance measuring sensor may be further provided, whereby the distance to the display unit 180Q may be sensed.

The output unit 250Q may output a video or audio signal corresponding to the operation of the user input unit 235Q or corresponding to the signal transmitted from the control unit 170Q of the broadcast signal receiver 100Q.

The user may recognize whether the user input unit 235Q is manipulated or whether the broadcast signal receiver 100Q is controlled through the output unit 250Q.

For example, the output unit 250Q is an LED module 251Q that is turned on when the user input unit 235Q is operated or a signal is transmitted and received with the broadcast signal receiver 100Q through the wireless communication unit 225Q, and a vibration module generating vibration. 253Q), a sound output module 255Q for outputting sound, or a display module 257Q for outputting an image.

The power supply unit 260Q supplies power to the wireless input unit 200Q. The power supply unit 260Q may reduce power waste by stopping power supply when the wireless input unit 200Q does not move for a predetermined time. The power supply unit 260Q may resume power supply when a predetermined key provided in the wireless input unit 200Q is operated.

The storage unit 270Q may store various types of programs and application data necessary for controlling or operating the wireless input unit 200Q. If the wireless input unit 200Q transmits and receives signals wirelessly through the broadcast signal receiver 100Q and the RF module 221Q, the wireless input unit 200Q and the broadcast signal receiver 100Q transmit and receive signals through a predetermined frequency band. . The control unit 280Q of the wireless input unit 200Q may store and refer to the storage unit 270Q for information on a frequency band for transmitting and receiving a signal wirelessly with the broadcast signal receiver 100Q paired with the wireless input unit 200Q. Can be.

The controller 280Q controls various items related to the control of the wireless input unit 200Q. The control unit 280Q receives a signal corresponding to a predetermined key operation of the user input unit 235Q or a signal corresponding to the movement of the wireless input unit 200Q sensed by the sensor unit 240Q through the wireless communication unit 225Q. 100Q).

7 to 37 are diagrams for explaining the voice mode. Hereinafter, the description of the parts described in detail above will be omitted.

Referring to FIG. 7, the sound sensing unit 191Q may be disposed on the edge 100 of the display unit 180Q to execute the voice mode. The sound sensing unit 191Q may be a microphone capable of detecting sound.

As such, when the sound sensing unit 191Q is formed at the edge 100 of the display unit 180Q, sound generated at various positions may be detected.

Alternatively, as in the case of FIG. 8, the sound sensing unit 191Q may be disposed in the wireless input unit 200Q of the command input unit 160Q.

In this case, the user may input a command by voice to the wireless input unit 200Q.

For example, in addition to the sound sensing unit 191Q, the wireless input unit 200Q may include a numeric input key 200, a channel up key 210, a channel down key 211, and a volume up key. The apparatus may further include at least one of an up key 220, a volume down key 221, and a power key 230.

Alternatively, although not shown, an arrangement position of the sound sensing unit 191Q for the voice mode may not be limited to the display unit 180Q and the wireless input unit 200Q.

For example, the broadcast signal receiver 100Q according to the present invention may be disposed in a living room, and when the user inputs a voice command in the kitchen, the sound sensing unit 191Q may be disposed at various locations such as a refrigerator and a sink. .

In this case, the sensing unit 191Q may transmit / receive a command through communication with the control unit 170Q of the broadcast signal receiver 100Q according to the present invention.

The broadcast signal receiver 100Q according to the present invention may be set to a voice mode when a voice recognition call command is input.

For example, as in the case of FIG. 9, whether the voice recognition call command is input may be determined 300, and when the voice recognition call command is input, the voice mode may be activated 310.

Here, the voice mode may be a mode in which a user inputs a command to the broadcast signal receiver 100Q in voice to control the operation of the broadcast signal receiver 100Q.

In the voice mode, it may be determined whether a voice command is input 320, and when the voice command is input, the voice command may be executed.

In other words, when a voice recognition call command is received through the sound sensing unit 191Q, the voice mode is activated, and at least, the voice command corresponds to a voice command among a plurality of objects displayed on the display unit 180Q in the voice mode. The user may select one object or perform a preset function in response to a voice command.

As such, when a voice recognition call command for invoking the voice mode is set, an unnecessary operation process may be omitted in the standby mode before the voice mode is invoked. Accordingly, power consumption can be reduced, and the driving circuit can be simplified.

Here, the voice recognition call command is a call word for invoking the voice mode and may not have the authority to change the setting of the broadcast signal receiver 100Q.

In addition, the voice recognition call command can be set directly by the user.

The voice command may be a signal for changing the function, setting, etc. of the broadcast signal receiver 100Q or selecting a predetermined object in the voice mode. Such a voice command may be directly set by the user.

If the voice recognition call command is not input, the voice command may not be executed even if the voice command is input.

For example, suppose that the voice recognition call command is set to "LG" and the voice command is set as in the case of FIG.

Here, as in the case of FIG. 11, when the power signal is turned on at time t0 and the broadcast signal receiver 100Q is operated, and then a voice recognition call command is input at time t1, the broadcast signal is received from time t0 to time t1. The receiver 100Q may operate in a normal mode instead of a voice mode.

In such a normal mode, the broadcast signal receiver 100Q may output video / audio.

Thereafter, the broadcast signal receiver 100Q may operate in the voice mode by a voice recognition call command from time t1 to time t2 when the power is turned off.

In such a voice mode, the broadcast signal receiver 100Q may output an image / audio according to the voice mode.

Here, suppose that a voice command “large” is input to the sound sensing unit 191Q in a period between a time t0 and a time t1. In this case, since the voice mode is not provided from the time point t0 to the time point t1, the volume of the voice output by the broadcast signal receiver 100Q may not change even when a voice command “large” is input.

On the other hand, when the voice command "large" is input to the acoustic sensing unit 191Q in the period between the time t1 and the time t2, the voice output by the broadcast signal receiver 100Q in response to the voice command "large" is output. The volume of the volume may increase.

In such a case, it may be said that a preset function, that is, a volume up function, is executed in response to the voice command "large".

Alternatively, as in the case of FIG. 12, assume that a predetermined object 400 is displayed on the screen of the display unit 180Q and the pointer 205Q indicates the displayed object 400.

In this case, when the user inputs the voice command “Selection” described in FIG. 10 to the sound sensing unit 191Q, the object 400 displayed on the display unit 180Q is selected under the control of the controller 170Q. It can be chosen.

After the object 400 is selected, when a voice command of "delete" is input, the selected object 400 may be deleted.

Also, when the voice recognition cancel command is input while the voice recognition call command is input and the voice mode is activated, the voice mode may be released.

For example, as in the case of FIG. 13, assume that a voice recognition cancel command is input at a time t2 while a voice mode is maintained.

In this case, the broadcast signal receiver 100Q may operate in the normal mode instead of the voice mode from the time t2 to the time t3 when the power is turned off.

Here, the voice recognition release command is a caller for releasing the voice mode and may not have the authority to change the setting of the broadcast signal receiver 100Q.

In addition, the voice recognition cancel command can be set directly by the user.

In addition, at least one of a voice recognition call command and a voice recognition release command may be input by anyone regardless of a log-on user.

For example, assuming that the first user is currently logged on, it is possible for the first user, the second user, and the third user to input a voice recognition call command to invoke the voice mode.

Conversely, it may also be possible for only the currently logged on user to invoke the voice mode using a voice recognition call command.

Alternatively, users allowed by the currently logged on user may invoke the voice mode by using a voice recognition call command.

For example, assuming that the first user is currently logged on and the first user has made the second user available, the first user and the second user enter a voice recognition call command to invoke the voice mode. Although it is possible to do so, the first and second users and other third users may not activate the voice mode even when the voice recognition call command is input.

In addition, regardless of the user who inputs the voice recognition call command to activate the voice recognition mode, a plurality of users may release the voice mode by using the voice recognition release command.

For example, when the first user invokes the voice mode using a voice recognition call command, a second user and a third user different from the first user may also release the voice mode using the voice recognition release command.

Alternatively, other users allowed by the user who activated the voice mode may release the voice mode by using the voice recognition cancel command, and other users who are not allowed by the user who activates the voice mode may activate the voice mode even if the user inputs the voice recognition cancel command. You may not be able to release it.

Alternatively, only the user who activated the voice mode by using the voice recognition call command may release the voice mode by using the voice recognition release command.

Alternatively, the voice recognition call command and the voice recognition release command may be associated with each other.

For example, as in the case of Fig. 14, in the first type, the voice recognition call command may be set to "LG", and the voice recognition release command may be set to "GL".

In the second type, the voice recognition call command can be made "start", and the voice recognition cancel command can be made "end".

In the third type, the voice recognition call command can be " go ", and the voice recognition cancel command can be " stop ".

In this case, it is possible to release the voice mode when the voice recognition cancel command input by the user corresponds to the voice recognition call command.

An example thereof will be described below with reference to FIG. 15. In FIG. 15, a description of overlapping parts similar to those of FIG. 9 will be omitted.

Referring to FIG. 15, it is determined whether a voice recognition cancel command is input (340), and if the voice recognition cancel command is input, it is determined whether the voice recognition cancel command is the same type as a voice recognition call command (350). can do.

For example, when the input voice recognition cancel command is "GL", it is determined whether or not the voice recognition call command that triggered the voice mode is "LG".

If the voice recognition cancel command is the same type as the voice recognition call command, the voice mode may be released 360.

However, if the voice recognition cancel command is of a different type than the voice recognition call command, it can be maintained without canceling the voice mode.

Alternatively, even if the voice recognition cancel command is not input, it may be possible to automatically cancel the voice mode after a predetermined time after the voice recognition call command is input or after a predetermined time after the last voice command is input.

An example thereof will be described below with reference to FIGS. 16 and 17. In FIG. 17, description of overlapping parts similar to those of FIG. 9 will be omitted.

As in the case of FIG. 16, assume that a voice mode is invoked when a voice recognition call command is input at a time t1.

In this case, it may be determined 400 whether the threshold time is exceeded in the voice mode.

Here, the threshold time may be variously set according to the user. For example, the threshold time may be set to one minute. In this case, when the voice command is not input in the voice mode, it may be determined that the threshold time is exceeded when the voice recognition release command is not input for one minute after the voice recognition call command is input. Alternatively, when the voice recognition cancel command is not input for one minute after the last voice command is input, it may be determined that the threshold time has been exceeded.

For example, in FIG. 16, when the threshold time is W1 and there is no input of a voice command from time t1 to time t4 after a predetermined time, the voice mode may be canceled even if the voice recognition cancel command is not input at time t4. .

As a result of determination, when the threshold time is exceeded in the voice mode, the voice mode may be released (410).

The voice command may be edited and used by a user.

For example, as in the case of FIG. 18, it is possible to edit a voice command by using a pointer 205Q in the edit mode to change a character string of a voice command corresponding to a predetermined function.

10 and 18, it can be seen that voice commands corresponding to the same function are different.

On the other hand, in order to allow the user to more easily check and use the voice command, as shown in FIG. 19, it is possible to display the voice command on the screen of the display unit 180Q.

Alternatively, as illustrated in FIG. 20, the voice command corresponding to various input keys of the wireless input unit 200Q may be displayed together with the wireless input unit 200Q to display the voice command.

Or, it may provide a practice mode for improving the proficiency of the user's voice mode.

For example, as in the case of FIG. 21, in the practice mode, the user may practice inputting a "big" voice command for a predetermined function, for example, a volume up function.

In more detail, as in the case of FIG. 22, it is determined whether the practice mode is executed 500, and when the practice mode is executed, various voice commands, voice recognition call commands, and voice recognition canceled on the display unit 180Q. The command may be displayed 510.

Thereafter, it may be determined whether the voice command input by the user for the predetermined function is good enough to execute the corresponding function (520). For example, in FIG. 21, it is determined whether the "large" input by the user is clear and good enough to execute a function corresponding to volume up.

As a result of determination, another command may be displayed on the screen (530). Alternatively, other commands may be indicated on the screen. For example, in FIG. 21, the volume down function may be indicated after the volume up.

The user can then perform exercises for other commands.

Alternatively, when the user selects a predetermined function for improving the proficiency of the user's voice mode, it is possible to output a voice command corresponding to the selected function.

In this case, the user can directly hear the voice command corresponding to the function selected by the user.

For example, as in the case of FIG. 23, when a user selects 610 a predetermined key, for example, a volume increasing key, disposed in the wireless input unit 200Q in a practice mode, a voice command corresponding to the volume increasing key, for example As shown in FIG. 21, the output may be 620.

Meanwhile, when there are a plurality of users, each user may set different voice recognition call commands, voice recognition release commands, voice commands, and the like.

For example, as in the case of FIG. 24, the voice recognition call command of the first user is different from the voice recognition call command of the second user, or the voice recognition release command of the first user is different from the voice recognition release command of the second user. Alternatively, the at least one voice command of the first user may be different from the voice command of the second user.

As such, the string of the voice recognition call command of the first user is different from the string of the voice recognition call command of the second user, or the string of the voice recognition release command of the first user is different from the string of the voice recognition release command of the second user. The string of at least one voice command of the first user may be different from that of the voice command of the second user.

In this case, personal information, preference channel information, etc. of each user can be prevented from leaking to others.

Meanwhile, the frequency band of the voice recognition call command of the first user is different from the frequency band of the voice recognition call command of the second user, or the frequency band of the voice recognition release command of the first user is determined by the voice recognition release command of the second user. It may be different from the frequency band, or the frequency band of at least one voice command of the first user may be different from the frequency band of the voice command of the second user.

For example, as in the case of FIG. 25, the frequency band of the voice recognition call command of the first user may be 10 Hz to 50 Hz, and the frequency band of the voice recognition call command of the second user may be 500 Hz to 20 Hz. .

In this case, the voice recognition call command of the first user and the voice recognition call command of the second user may be the same.

For example, even when the voice recognition call command of the first user and the second user is "LG", the frequency bands of the voice recognition call command of the first user and the voice recognition call command of the second user are different from each other. Can be.

In this case, the voice tone of the first user may be a low tone, and the voice tone of the second user may be a high tone.

On the other hand, the accent of the voice recognition call command of the first user is different from the accent of the voice recognition call command of the second user, or the accent of the voice recognition release command of the first user is different from that of the voice recognition release command of the second user. The accent of the at least one voice command of the first user may be different from the accent, or may be different from the accent of the voice command of the second user.

For example, suppose that the voice recognition call command of the first user and the voice recognition call command of the second user are "hungry" as in the case of FIG.

In this case, the accent of the first user may be at "double" and the accent of the second user may be at "da".

In this case, even if the voice recognition call command of the first user and the voice recognition call command of the second user are the same as "hungry," when the first user and the second user pronounce "hungry" in different accent patterns, the broadcast signal is broadcast. The receiver 100Q may distinguish a user.

Meanwhile, the voice pattern of the voice recognition call command of the first user is different from the voice pattern of the voice recognition call command of the second user, or the voice pattern of the voice recognition release command of the first user is the voice pattern of the voice recognition release command of the second user. It may be different from the voice pattern or the voice pattern of the at least one voice command of the first user may be different from the voice pattern of the voice command of the second user.

For example, as in the case of FIG. 27, the voice pattern of the voice recognition call command of the first user and the voice pattern of the voice recognition call command of the second user may be different from each other.

In this case, the voice recognition call command of the first user and the voice recognition call command of the second user may be the same.

For example, even when the voice recognition call command of the first user and the second user is "LG", the voice patterns of the first user's voice recognition call command and the second user's voice recognition call command are different from each other. Can be.

The voice pattern may be obtained by analyzing the voice of each user.

On the other hand, it is possible to activate different voice modes according to a user who inputs a voice recognition call command.

For example, as in the case of FIG. 28, it is determined 700 whether a voice recognition call command is input, and when the voice recognition call command is input as a result of the determination, the input voice recognition call command is a command of the first user. That is, whether or not the first voice recognition call command may be determined 710. Here, it may be determined whether the character string of the input voice recognition call command corresponds to the first voice recognition call command set by the first user.

As a result of the determination, when the inputted voice recognition call command corresponds to the first voice recognition call command set by the first user, the frequency, voice pattern, or accent pattern of the input voice recognition call command is different from the contents set by the first user. It may be determined 720 whether or not matching.

As a result of the determination, when the frequency, voice pattern, or accent pattern of the input voice recognition call command matches contents set by the first user, the first voice mode corresponding to the first user may be activated 730.

If it is determined in step 710 that the voice recognition call command is not the first voice recognition call command of the first user, the input voice recognition call command is a command of the second user, that is, the second voice recognition call command. It may be determined (740). Here, it may be determined whether the character string of the input voice recognition call command corresponds to the second voice recognition call command set by the second user.

As a result of the determination, when the input voice recognition call command corresponds to the second voice recognition call command set by the second user, the frequency, voice pattern, or accent pattern of the input voice recognition call command is different from the contents set by the second user. It may be determined 750 whether a match is found.

As a result of the determination, when the frequency, voice pattern, or accent pattern of the input voice recognition call command matches contents set by the second user, a second voice mode corresponding to the second user may be activated 760.

As described above, it is possible to execute different voice modes when different users log on.

In addition, when a voice command is input in the voice mode, the command execution can be determined according to whether the input voice command corresponds to the user who invoked the voice mode.

For example, as in the case of FIG. 29, when the voice mode is activated 800, whether or not a voice command is input may be determined 810.

As a result of the determination, when a voice command is input, it may be determined whether the input voice command matches the user who invoked the voice mode by using the frequency, the voice pattern, the accent pattern, and the string. .

As a result of the determination, when the input voice command matches the user who activated the voice mode, the input voice command may be executed.

If the second user inputs the voice command while the first user activates the voice mode using the voice recognition call command, the voice command input by the second user may not be executed.

Meanwhile, when the voice recognition call command is input and the voice mode is executed, as shown in FIG. 30, a mark 900 indicating that the voice mode is being executed may be displayed on the screen of the display unit 180Q.

Alternatively, as shown in FIG. 31, a notification unit 910 such as an LED for notifying that the voice mode is running may be formed on the edge 100 of the display unit 180Q. In this case, in the voice mode, the notification unit 910 lights up in red, indicating that the voice mode is being executed.

Meanwhile, when a plurality of users set a voice recognition call command, priority may be set for each voice recognition call command.

For example, as in the case of FIG. 32, the user of the broadcast signal receiver 100Q according to the present invention has four fathers, mothers, sons, and daughters, and the father's voice recognition call command is " LG " Assume that the voice recognition call command is "Make Money", the son's voice recognition call command is "Hungry", and the daughter's voice recognition call command is "Buy Me."

In this case, priority may be assigned to the voice recognition call command of each user. For example, assign the first priority to the father's voice recognition call command "LG", assign the second priority to the mother's voice recognition call command "Money Making" and the son's voice recognition call command. A third priority can be assigned to "Hungry", and a fourth priority can be assigned to the daughter's voice recognition call command "Bab Me".

If a plurality of users input a voice recognition call command at the same time or nearly simultaneously, the voice recognition call command having a priority among the plurality of voice recognition call commands may be selected.

For example, as in the case of FIG. 33, it is determined whether or not a plurality of voice recognition call commands are input (1000). When a plurality of voice recognition call commands are input, the priority of each voice recognition call command is determined. Compare 1010.

Thereafter, one voice recognition call command having a higher priority among a plurality of voice recognition call commands may be selected and applied according to the comparison result.

For example, if "LG", the father's voice recognition call command with the first priority, and "Hungry," the voice recognition call command with the son with the third priority, are entered together, The voice mode can be activated in response to the voice recognition call command "LG". In other words, the voice mode set by the father can be activated.

Alternatively, when another voice recognition call command is input while the voice mode is activated, the voice mode is changed according to the priority of the newly input voice recognition call command and the priority of the voice recognition call command that activated the current voice mode. You can decide whether to switch.

For example, as in the case of FIG. 34, it is determined whether a first voice recognition call command according to the first user is input (1100), and when input, the first voice mode corresponding to the first voice recognition call command. Can be activated 1110.

Subsequently, it is determined whether a second voice recognition call command according to a second user different from the first user is input (1120), and if so, the priority of the first voice recognition call command and the second voice recognition call command are determined. Priorities may be compared 1130.

As a result of the comparison, when the priority of the second voice recognition call command is higher than the priority of the first voice recognition call command, the first voice mode may be switched 1140 to the second voice mode.

Alternatively, when the comparison result indicates that the priority of the second voice recognition call command is lower than the priority of the first voice recognition call command, the first voice mode may be maintained 1150.

That is, when another voice recognition call command is input while the voice mode is activated, the priority of the newly input voice recognition call command is higher than the priority of the voice recognition call command that has activated the current voice mode. Switch to the voice mode corresponding to the newly input voice recognition call command, and vice versa if the priority of the newly input voice recognition call command is lower than the priority of the voice recognition call command that invoked the current voice mode. To maintain.

Meanwhile, although only the case where the voice recognition call command is in the acoustic form has been described, the voice recognition call command for activating the voice mode may be in the form of a gesture of a user.

This will be described in more detail below. Hereinafter, the description of the parts described in detail above will be omitted. For example, hereinafter, the voice recognition call command only changes from sound to motion, and the content of the voice command and the like may be substantially the same as the above.

Referring to FIG. 35, the motion sensing unit 192Q may be disposed on the edge 100 of the display unit 180Q to execute a voice mode using a user's movement. The motion sensing unit 192Q may be a camera capable of detecting a user's movement.

Alternatively, the motion sensing unit 192Q may be physically spaced apart from the display unit 180Q. For example, the broadcast signal receiver 100Q according to the present invention may be disposed in the living room, and the motion sensing unit 192Q may be disposed in the ceiling of the living room.

The user may set the broadcast signal receiver 100Q to the voice mode by using a predetermined movement.

For example, the user may set an operation such as clapping, jumping, rotating, tumbling, kicking, etc. as a voice recognition call command in advance, and use the same to activate the voice mode.

For example, when the user sets "front kick" as the voice recognition call command, the broadcast signal receiver 100Q may enter the voice mode when the user takes the "front kick" operation.

In addition, a voice recognition cancel command for releasing the voice mode may also be set by a user's movement such as "jump". Alternatively, as described in detail above, the voice recognition cancel command may be a voice signal such as "end".

Meanwhile, a voice recognition call command, which is a motion, may vary according to a user.

For example, as in the case of FIG. 36, the first user is set to the first operation of swinging the arm up and down with a voice recognition call command, and the second user is a first state in which the arms are spread from side to side with the voice recognition call command. Can be set to 2 operations.

In this case, when the user takes the first operation, the broadcast signal receiver 100Q may enter a voice mode corresponding to the first operation.

In addition, as well as the voice recognition call command of each user, it is possible to set each user's height, body shape, face contour, and the like.

Here, the key, body shape, facial contour, etc. may be directly input by the user. Unlike this, the motion sensing unit 192Q of the broadcast signal receiver 100Q may photograph the user to set and store information such as height, body heat, and facial contour.

In this case, it is possible to distinguish whether the user who takes a predetermined operation for inputting the voice recognition call command is a user corresponding to the voice recognition call command.

For example, as in the case of FIG. 37, it is determined whether a motion command (voice recognition call command) is input (1200). When the voice recognition call command is input as a result of the determination, the input voice recognition call command is determined. It may be determined 1210 whether the command of the first user, that is, the first voice recognition call command. Here, it may be determined whether the operation pattern of the input voice recognition call command corresponds to the operation pattern of the first voice recognition call command set by the first user.

As a result of the determination, when the operation pattern of the input voice recognition call command corresponds to the operation pattern of the first voice recognition call command set by the first user, a key, a body shape, a face contour, etc. of the user who inputs the voice recognition call command It may be determined whether the content matches the content set by the first user (1220).

As a result of the determination, when a key, a shape, and the like of the user who inputs the voice recognition call command match the contents set by the first user, the first voice mode corresponding to the first user may be activated 1230.

If it is determined in operation 710 that the key, body shape, etc. of the user who inputs the voice recognition call command do not match the contents set by the first user, the input voice recognition call command is the second user's command; That is, it may be determined whether it is the second voice recognition call command (1240). Here, it may be determined whether the operation pattern of the input voice recognition call command corresponds to the operation pattern of the second voice recognition call command set by the second user.

As a result of the determination, when the operation pattern of the input voice recognition call command corresponds to the operation pattern of the second voice recognition call command set by the second user, a key, a body shape, a face contour, etc. of the user who inputs the voice recognition call command In operation 1250, it may be determined whether the content matches the content set by the second user.

As a result of determination, when a key, a shape, and the like of the user who inputs the voice recognition call command match the contents set by the second user, the second voice mode corresponding to the second user may be activated 1260.

38 to 53 are views for explaining the voice menu mode. In the following, description of the details described above will be omitted.

The broadcast signal receiver 100Q according to the present invention may output information of a menu displayed on the display unit 180Q through a voice output unit. That is, the menu displayed on the screen is spoken by voice. Hereinafter, this is called a voice menu mode.

If the user does not need to view an image displayed on the display unit 180Q, it may be possible to output only a voice without displaying a menu on the display unit 180Q.

Hereinafter, for convenience of explanation and understanding, it is assumed that the menu is displayed on the screen of the display unit 180Q, and the information of the displayed menu is output by voice. However, the following description may also be applied to a case in which information of a menu not displayed on the display unit 180Q is output by voice.

Referring to FIG. 38, menus may be displayed on the display unit 180Q. For example, ① category, ② favorite channel, ③ search, ④ Health Care, ⑤ external input, ⑥ setting, etc. may be displayed on the display unit 180Q.

As described above, when there are a plurality of menus, information of the plurality of menus may be sequentially output as voice. For example, as in the case of FIG. 39, information of each menu can be output by voice in the order of ① category, ② favorite channel, ③ search, ④ health care, ⑤ external input, and ⑥ setting.

The information of the menu output as voice may include at least one of a menu name and a menu number.

In addition, information of a menu selected by a user among a plurality of menus displayed on the screen of the display unit 180Q may be output through the voice output unit.

For example, as shown in FIG. 40, when the user selects the menu item “health care” from among a plurality of menus using the pointer 205Q, the user may perform “health” through the voice output unit under the control of the controller 170Q. Information of the “Care” menu may be output as voice.

In this case, an illiterate user may use various menus of the broadcast signal receiver 100Q according to the present invention.

In addition, a user with poor vision may easily use various menus by using a voice menu provided by the broadcast signal receiver 100Q according to the present invention.

Alternatively, various menus provided by the broadcast signal receiver 100Q according to the present invention can be easily used while doing other tasks such as washing dishes and cleaning.

On the other hand, when the information of the menu is output by voice, the user may listen to the information of the menu output by the voice and input a menu selection signal to select desired information. Here, the menu selection signal is a signal for selecting a predetermined menu provided by voice.

For example, as in the case of FIG. 41A, the first user and the second user may set a menu number and / or a menu name as a menu selection signal.

In this case, the first user or the second user can select the desired menu by uttering the number of the menu to be selected and / or the name of the menu.

In FIG. 41A, the menu selection signal of the first user and the menu selection signal of the second user may have the same character string. In this case, the menu selection signal of the first user and the menu selection signal of the second user may have different frequency bands, voice patterns, and / or accent patterns.

Accordingly, even if the menu selection signal of the first user and the menu selection signal of the second user have the same character string, it is necessary for the broadcast signal receiver 100Q to determine whether the user who selects the menu is the first user or the second user. It is possible.

For example, when the second user makes a menu selection signal while the first user is logged on, the control unit 170Q of the broadcast signal receiver 100Q may use the frequency band, voice pattern, and / or accent of the menu selection signal. The menu selection signal input locally using the pattern may be determined as not input by the first user, and thus the menu selection signal may not be selected.

Alternatively, as in the case of FIG. 41 (B), the menu selection signal (“here”) of the first user and the menu selection signal (“stop”) of the second user may have different character strings.

The menu selection signal of each user can be set directly by the user.

In this case, the first user or the second user can select a desired menu by uttering his menu selection signal.

For example, as in the case of Fig. 42, " ① category " at time t0, " ② preferred channel " at time t1, " ③ search " at t2 time, " Health Care " At the time point "5 external input", at time t5 "6 setting" information can be output by voice.

Here, when a user allowed between a time point t3 and a time point t4 inputs a menu selection signal such as “there”, the control unit 170Q of the broadcast signal receiver 100Q selects the “Health Care” menu. You can choose.

In other words, when a menu selection signal is input through the sound sensing unit, a menu that outputs information through the voice output unit may be selected.

As such, when the previous menu is selected in the process of voice outputting the information of the menu, it may be preferable that the difference Δt between two consecutive voice information output points of the menu information is long enough.

If the user uses the menu name and / or the menu number as the menu selection signal as in the case of FIG. 41A, when the menu input signal is input between the time point t0 and the time point t5, the sequence of voice output is performed. Irrespective of the menu, a menu corresponding to the input menu selection signal can be selected.

On the other hand, if the user wants to hear the information of the previous menu again, the user may use the menu repeat signal.

For example, as in the case of FIG. 43, when a user allowed between a time point t3 and a time point t4 inputs a menu repetition signal, at the time point t4, a "④Health Care" menu outputs voice at a time point t3. The audio information can be output again.

That is, when the menu repetition signal is input, the information of the previous menu may be duplicated and output.

Although FIG. 43 illustrates a case in which the information of the immediately preceding menu is duplicated when the menu repetition signal is input, the information of a plurality of previously output menus may be output again.

On the other hand, when a predetermined menu is selected using a menu selection signal in the process of outputting menu information by voice in the voice menu mode, it is possible to voice output information of a sub menu of the selected menu.

For example, as in the case of Fig. 44, menus in the order of " ① category ", " ② preferred channel ", " ③ search ", " Health Care ", " ⑤ external input " In the process of outputting the information by voice, suppose that the permitted user inputs a menu selection signal and selects the "④Health Care" menu.

In this case, the submenu of "Health Care" menu "① blood pressure", "② pulse", "③ body temperature", "④ symptoms", "⑤ consultation", etc. are displayed on the display unit 180Q. can do.

In addition, menu information such as “① blood pressure”, “② pulse”, “③ body temperature”, “④ symptom”, and “⑤ consultation”, which are sub-menus of the “Health Care” menu, may be voice output. .

Even in such a case, it is possible for the user to select a submenu of the "Health Care" menu using the menu selection signal.

On the other hand, it is possible to change the audio output order of the menu information in various ways.

For example, the user may directly set the voice output order of the menu information. In this case, the menu information may be output in the audio in the order set by the user.

Alternatively, the voice output order of the menu information may be determined according to the preference.

Assume that the plurality of menus include a first menu, a second menu, and a third menu. In this case, the number of times selected by the user is greater than the number of times selected by the user of the second menu and the number of times that the first menu is selected by the user of the third menu is greater than that of the second menu and the third menu. The output order of the information may be in the order of the first menu, the third menu, and the second menu.

For example, as in the case of FIG. 45, the number of selections of "1" category is 21, the number of selections of "2" preferred channel "is 36, the number of selections of" 3 "search is 50, and" 4 "healthcare is selected for a predetermined period. Suppose that the number of times of "Health Care" is 110, the number of times of "5 external input" is 3, and the number of times of "6" is 1 is selected.

In this case, select "Health Care", "③ Search", "② Preferred Channel", "① Category", "⑤ External Input", and "⑥ Settings" in order of increasing number of selections for a predetermined period. Menu information can be output in audio order.

Here, the predetermined period can be determined by the user. For example, it can be set in various ranges, such as 1 day, 1 week, 1 month, and 1 year.

Alternatively, the number of voice outputs may be adjusted according to the preference of the menu.

It is assumed that the plurality of menus include a first menu and a second menu, and the number of times selected by the user is greater than that of the second menu. In this case, the number of times of outputting the information through the voice output unit may be greater in the first menu than in the second menu.

For example, as in the case of FIG. 45, when the number of selections of each menu for a predetermined period is determined, as in the case of FIG. 46, the number of audio outputs for the predetermined period is determined according to the order in which the number of selections is greatest. (Health Care) "menu 6 times," ③ "menu 5 times," ② favorite channel "menu 4 times," ① category "menu 3 times," ⑤ external input "menu 2 times," ⑥ Settings "menu can be set once.

That is, the more frequently selected menus (menus having high preference) for a predetermined period of time, the more the number of voice outputs.

Alternatively, the time difference between voice output points may be adjusted according to the preference of the menu.

Assume that the plurality of menus include a first menu, a second menu, a third menu, and a fourth menu. Here, the number of times selected by the user is greater than the second menu, the third menu, and the fourth menu, and the number of times selected by the user of the second menu is the number of times selected by the user of the third menu and the fourth menu. When more than the number of times selected by the user, the time difference between the output time of the information of the first menu and the output time of the information of the second menu is the difference between the output time of the information of the third menu and the output time of the information of the fourth menu. It can be greater than the time difference.

For example, as in the case of FIG. 45, when the number of selections of each menu for a predetermined period is determined, as in the case of FIG. 47, the voice output time point t0 and "③ of" Health Care "are defined. The time difference T1 of the voice output time point t1 of the "search" may be greater than the time difference T3 between the voice output time point t2 of the "2 favorite channel" and the voice output time point t3 of the "① category". .

In other words, the more frequently selected menus (menus having high preference) for a predetermined period, the longer the period of voice output.

In the above case, the user may obtain more opportunities to select a menu with high preference.

Alternatively, the menu for outputting voice may also be different from each other.

For example, as in the case of FIG. 48A, when the first user is logged on, information of a menu according to the first user may be output through the voice output unit. In addition, the menu according to the first user may be displayed on the display unit 180Q.

In addition, as in the case of FIG. 48B, when a second user different from the first user is logged on, information of a menu according to the second user may be output through the voice output unit. In addition, the menu according to the second user may be displayed on the display unit 180Q.

Here, the menu according to the first user and the menu according to the second user may be different. This is because the menu preferred by the first user and the second user may be different.

Comparing FIG. 48 (A) with FIG. 48 (B), it can be seen that the "④Health Care" menu of FIG. 48A has been changed to the "④E-Mail" menu. Can be.

Alternatively, even when the menu of the first user and the menu of the second user are the same, the number of outputs, a time point, and an order of each menu may be different.

For example, as in the case of Fig. 49, the first user has selected 21 times the number of categories "1", the number of times the number "2" is selected, and the number of times the number "3" is selected. 50, the number of times for selecting "Health Care" is 110, the number of times for selecting "1" category is 200 for the second user during the first period, and the number of times for selecting "2." Suppose that the number of selections in the "search" is 50 and the number of selections in the "Health Care" is two.

In this case, when the first user is logged on in the order of increasing the number of selections during the first period, in the order of "Health Care", "③ Search", "② Preferred Channel", and "① Category" When the second user is logged on, the menu information can be output in the order of "① category", "② preferred channel", "③ search", and "④Health Care". have.

That is, even when the menu of the first user and the menu of the second user are the same, the output order of the predetermined menus may be different from when the first user is logged on and when the second user is logged on.

Alternatively, as shown in FIG. 50, when the first user is logged on, the number of voice outputs of each menu item for the first period is set to "④Health Care", "③ search", "② preferred channel", " In the order of "category", when the second user is logged on, the order of "category", "② favorite channel", "③ search", and "④ health care" can be increased in order.

That is, even when the menu of the first user and the menu of the second user are the same, the number of outputs of the predetermined menu may be different from when the first user is logged on and when the second user is logged on.

Alternatively, as in the case of FIG. 51, when the first user is logged on, the voice output time point t0 of "Health Care" and the voice output time point t1 of "③ Search" within the first period are displayed. The time difference T1 is greater than the time difference T3 between the voice output time point t2 of the "2 favorite channel" and the voice output time point t3 of the "1" category, and the first period when the second user is logged on. The time difference T11 between the voice output time point t10 of the "category" and the audio output time point t11 of the "② favorite channel" within the voice output time point t12 of the "③ search" and the "④ health care" (Health Care) "can be made larger than the time difference T13 of the audio | voice output time point t13.

That is, even when the menu of the first user and the menu of the second user are the same, the time difference between the output time points of two consecutive menus may be different from when the first user is logged on and when the second user is logged on. will be.

On the other hand, when there are a plurality of users, a menu for voice output corresponding to a user who inputs a menu selection signal for selecting a menu may vary.

For example, as shown in FIG. 52, when the voice menu is output 1300 in the voice menu mode, it may be determined whether the menu selection signal is input by the user (1310).

When the menu selection signal is input, it may be determined whether the input menu selection signal is a command of the first user, that is, the first menu selection signal (1320). For example, it may be determined whether the character string of the menu selection signal corresponds to the character string of the first menu selection signal set by the first user.

As a result of the determination, when the input menu selection signal corresponds to the character string of the first menu selection signal set by the first user, it may be determined whether the input menu selection signal matches the first user (1330). Here, the frequency, voice pattern, accent pattern, character string, etc. of the input menu selection signal may be analyzed to determine whether the input menu selection signal matches the first user.

As a result of the determination, when the input menu selection signal matches the first user, the menu according to the first user may be output as voice 1340. In addition, a menu corresponding to the first user may be displayed on the display unit 180Q.

For example, as in the case of FIG. 53A, the display unit displays submenus ①OCN, ②CGV, ③Ongame, and ④MBCgame, which are submenus of the menu of a favorite channel ② corresponding to the first user. The display may be displayed at 180Q or output as voice.

If it is determined in operation 1320 that the input menu selection signal is not the command of the first user, that is, the first menu selection signal, the input menu selection signal is the command of the second user, that is, the second menu selection signal. It may be determined whether or not the recognition. For example, it may be determined whether the character string of the menu selection signal corresponds to the character string of the second menu selection signal set by the second user.

As a result of the determination, when the input menu selection signal corresponds to the character string of the second menu selection signal set by the second user, it may be determined whether the input menu selection signal matches the second user (1360).

Here, the frequency, voice pattern, accent pattern, character string, etc. of the input menu selection signal may be analyzed to determine whether the input menu selection signal matches the second user.

As a result of the determination, when the input menu selection signal matches the second user, the menu according to the second user may be outputted as voice 1370. In addition, a menu corresponding to the second user may be displayed on the display unit 180Q.

For example, as shown in FIG. 53 (B), the submenus "1MBC", "2KBS1", "3KBS2" and "4BSS" which are sub-menus of the "2 favorite channel" menu corresponding to the first user are displayed. The display may be displayed at 180Q or output as voice.

54 to 69 are diagrams for explaining a function on a multichannel. In the following, description of the details described above will be omitted.

Referring to FIG. 54, images corresponding to a plurality of channels may be displayed together on the display unit 180Q. Hereinafter, this case will be referred to as a multichannel mode.

For example, an image corresponding to Movie 1 to 3 channels, an image corresponding to Sports 1 to 4 channels, and an image corresponding to Game 1 to 2 channels may be displayed together on the display unit 180Q.

The user may select at least one of the plurality of images displayed on the display unit 180Q and watch the selected image.

In addition, the user can edit the multichannel mode.

For example, images corresponding to a total of 12 channels may be displayed on one screen, and the user may arbitrarily change the arrangement order of the images.

In addition, the user may drag a predetermined image to move a position in the multi-channel mode.

In the multi-channel mode in which images of a plurality of channels are displayed together on the display unit 180Q, the size of the image of at least one channel may be adjusted according to the preference of the channel. In detail, in the broadcast signal receiver 100Q according to the present invention, the size of an image of a preferred channel may increase, become clearer, or become brighter in the multi-channel mode.

For example, as shown in FIG. 55, when the user sets the preferred category to Game, Movie 1 to 3 channels, Sports 1 to 4 channels, and Game 1 to 2 displayed on the display unit 180Q. The size of the video corresponding to the Game 1-2 channel among the channels may be larger than the video of other channels.

In this case, the size of the channel of the user's preferred category in the multi-channel mode increases, so that the user can more easily find and select the preferred channel.

In the multichannel mode, an image having an increased size may partially cover an image of another adjacent channel.

For example, as shown in FIG. 56, the size of an image corresponding to the Game 1 channel among the Movie 2 channel, Sports 2, 3 channel, and Game 1 channel displayed on the display unit 180Q is larger than that of other channels. The video corresponding to the Game 1 channel may partially cover the Movie 2 channel image as in the second region AR2, and the Sports 2 and 3 regions as in the first region AR1 or the third region AR3. Each part of the channel can be covered.

In addition, the edge 1400 of the image corresponding to the Game 1 channel may be thicker and thicker than the edge of the other image.

In this case, the image corresponding to the Game 1 channel preferred by the user can be made more prominent.

According to the increase in the size of the video, the video corresponding to the game 1 channel may not overlap with the video of the movie 2 channel and the video of the sports 2 and 3 channels.

On the other hand, it is possible to adjust the size of the image in the multi-channel according to the number of channel selection during a predetermined period.

In other words, the first image according to the first channel and the second image according to the second channel are displayed together on the display unit 180Q, and the number of times of selection by the user of the first channel is displayed. Assuming that the case is larger than the number of times selected by the user of the second channel, the size of the first image may be larger than the size of the second image.

For example, as shown in FIG. 57, 5, 120, and 30 times the number of selections of the Movie 1 to 3 channels displayed on the display unit 180Q, and 50, 4, 16, and 61 times the selection times of the Sports 1 to 4 channels. Suppose that the number of times, and the number of times of selecting the Game 1-2 channels are 100 or 80 times.

In this case, the number of selections of the Movie 2 channel among the plurality of channels is greater than that of the other channels. Accordingly, as shown in FIG. 58, the size of the image corresponding to the Movie 2 channel may be larger than that of the other channels. .

Alternatively, as in the case of FIG. 59, the size of the image may gradually increase according to the size of the number of selections during the predetermined period.

Alternatively, as in the case of FIG. 60, a plurality of images may be arranged in the order of the number of selections during a predetermined period.

For example, an image of the Movie 2 channel having the largest number of selections among the plurality of images may be disposed on the upper left of the display unit 180Q, and as the number of selections decreases, the image may be disposed on the right side or lower portion of the display unit 180Q. have.

In this case, the user can more easily find the preferred channel.

Alternatively, the size, order, etc. of the image may be adjusted in consideration of the viewing time of each channel.

In other words, the first image corresponding to the first channel and the second image corresponding to the second channel are displayed together on the display unit 180Q, and the viewing time of the first channel is determined by the second image. Assuming that the channel is longer than the viewing time, the size of the first image may be larger than that of the second image.

For example, as shown in FIG. 61, the viewing time of the Movie 1-3 channels displayed on the display unit 180Q is 30, 320, 60 hours, and the viewing times of the Sports 1-4 channels are 100, 20, 50, respectively. Suppose that the viewing time of,, 122 hours, and Game 1-2 channels are 200 and 160 hours, respectively. Here, the viewing time of the channel may be measured for a predetermined period. In addition, the viewing time may be referred to as the total display time of the video of the channel.

In this case, the viewing time of the Movie 2 channel among the plurality of channels is 320 hours, which is higher than that of other channels. Thus, as shown in FIG. 58, the size of the image corresponding to the Movie 2 channel is larger than that of the other channels. I can make it big.

The method of adjusting the size and the order of the image by the viewing time of the channel may be substantially the same as the method of adjusting the size and the order of the image by the number of times of the channel selection.

Alternatively, when the images according to the plurality of channels are displayed together on the display unit 180Q in the multi-channel mode, it is possible to adjust the brightness (brightness) of the images according to at least one channel according to the channel preference.

In other words, the first image according to the first channel and the second image according to the second channel are displayed together on the display unit 180Q, and the number of times of selection by the user of the first channel is selected by the user of the second channel. Assuming that the number is greater than the number, the luminance of the first image may be higher than the luminance of the second image.

Alternatively, it is assumed that the first image corresponding to the first channel and the second image corresponding to the second channel are displayed together on the display unit 180Q, and the viewing time of the first channel is longer than the viewing time of the second channel. The luminance of the first image may be greater than that of the second image.

For example, as shown in FIG. 57, when the number of selections of the plurality of channels is set, or when the viewing time of the plurality of channels is set as in the case of FIG. 61, the plurality of channels as shown in FIG. 62. The luminance (brightness) of an image corresponding to a Movie 2 channel having a longer viewing time or a greater number of selections may be higher than that of another channel.

For example, as in the case of (A) of FIG. 63, a video of a Movie 2 channel having a high preference, that is, a large number of selections or a long viewing time is relatively bright.

On the other hand, as in the case of FIG. 63 (B), the video of the Movie 2 channel with low preference, that is, the number of selections or the short viewing time is relatively brighter than the Movie 2 channel video.

To this end, it is possible to make the data gain of the video of the Movie 2 channel smaller than the data gain of the video of the Movie 1 channel. In this case, even when the Movie 2 channel image and the Movie 1 channel image are the same, the Movie 2 channel image may be darker than the Movie 1 channel image.

Alternatively, it may be possible to darken the image of the Movie 2 channel by artificially applying noise to the image of the Movie 2 channel.

As described above, when the image of the channel of high preference is made brighter or the image of the channel of low preference is made darker, the visibility of the image of the channel of high preference may be improved.

Alternatively, in the multi-channel mode, it is possible to adjust the size and brightness of the image in consideration of the channel preference.

For example, as shown in FIG. 57, when the number of selection of the plurality of channels is set, or when the viewing time of the plurality of channels is set as in the case of FIG. 61, the plurality of channels as shown in FIG. 64. The luminance (brightness) of an image corresponding to a Movie 2 channel having a longer viewing time or a greater number of selections can be made higher than that of another channel and larger than another channel.

Alternatively, at least one image of the plurality of channels may be simultaneously adjusted in size and brightness, the other at least one image may be adjusted only in size, or the other at least one image may be adjusted only in accordance with the preference of the channel.

In detail, the first image according to the first channel, the second image according to the second channel, and the third image according to the third channel are displayed together on the display unit 180Q, and the number of times of selection by the user of the first channel is displayed. Assume that the number of selections by the user of the second channel is greater than the number of selections by the user of the second channel and is greater than the number of selections by the user of the third channel.

In this case, the luminance of the first image is higher than the luminance of the third image, the size of the first image is larger than the size of the third image, the luminance of the first image is the same as the luminance of the second image, and the size of the first image is It may be larger than the size of the second image. Alternatively, the luminance of the first image is higher than the luminance of the third image, the size of the first image is larger than the size of the third image, the luminance of the first image is higher than the luminance of the second image, and the size of the first image is second It may be the same as the size of the image.

Alternatively, the first image according to the first channel, the second image according to the second channel, and the third image according to the third channel are displayed together on the display unit 180Q, and the viewing time of the first channel is displayed in the second channel. Pretend that it is longer than the viewing time and the viewing time of the second channel is longer than the viewing time of the third channel.

In this case, the luminance of the first image is higher than the luminance of the third image, the size of the first image is larger than the size of the third image, the luminance of the first image is the same as the luminance of the second image, and the size of the first image is It may be larger than the size of the second image. In addition, the luminance of the first image is higher than the luminance of the third image, the size of the first image is larger than the size of the third image, the luminance of the first image is higher than the luminance of the second image, and the size of the first image is second It may be the same as the size of the image.

For example, as in the case of FIG. 65, the preference of the first channel CH1 is higher than that of the second channel CH2, and the preference of the second channel CH2 is higher than that of the third channel CH3. Assume that the preference of the third channel CH3 is higher than the preference of the fourth channel CH4.

In this case, the size of the image of the first channel CH1 may be larger than the size of the image of the second channel CH2, the third channel CH3, and the fourth channel CH4.

In addition, the luminance of the image of the second channel CH2 may be higher than the luminance of the image of the third channel CH3 and the fourth channel CH4.

In addition, the luminance of the image of the first channel CH1 may be substantially the same as the luminance of the image of the second channel CH2.

That is, as the preference of the channel is improved, the luminance of the image is first increased, and if the channel is further improved, the size of the image can be increased.

Alternatively, as shown in FIG. 66, the size of the image of the first channel CH1 and the second channel CH2 may be larger than the size of the image of the third channel CH3 and the fourth channel CH4. Here, the preference of each channel of FIG. 66 is the same as the case of FIG.

In addition, the luminance of the image of the first channel CH1 may be higher than the luminance of the image of the second channel CH2, the third channel CH3, and the fourth channel CH4.

In addition, the size of the image of the first channel CH1 may be substantially the same as the size of the image of the second channel CH2.

In other words, as the preference of the channel is improved, the size of the image is first increased, and if the channel is further improved, the brightness of the image can be increased.

Accordingly, the luminance of the image of the first channel CH1 and the second channel CH2 having a larger size than that of the image of the third channel CH3 and the fourth channel CH4 may be different from each other.

In the above, the method for adjusting the size, brightness, and arrangement order of an image corresponding to at least one channel according to the channel preference in the multi-channel mode has been described. However, the size, brightness, order of the menu in consideration of the menu preference is described. It may also be possible to adjust the fonts.

For example, as in the case of FIG. 67, the luminance and size of at least one menu having a high preference among the plurality of menus displayed on the display unit 180Q may be higher than other menus. Since this method can be sufficiently inferred as a method of adjusting the size, brightness, and arrangement order of at least one image in the foregoing multichannel mode, further description is omitted.

Alternatively, although not shown, a character font of at least one menu having a high preference among a plurality of menus displayed on the display unit 180Q may be different from other menus. Even in this case, the visibility of the menu with high preference can be improved.

Meanwhile, it may be possible to display images corresponding to a plurality of channels by a slide method without displaying them on one screen. This is called a slide channel mode.

For example, as shown in FIG. 68, it is determined whether a slide channel mode execution command is input (1400), and when the slide channel mode execution command is input as a result of the determination, images of a plurality of channels are sequentially ordered in a slide method. Display 1410 may be performed. For example, an image may be displayed in order of an image of the first channel CH1, an image of the second channel CH2, an image of the third channel CH3, and an image of the fourth channel CH4.

Thereafter, it may be determined whether a slide channel selection command is input (1420).

As a result of determination, when a slide channel selection command is input, an image of the selected channel may be displayed (1430).

For example, as shown in FIG. 69, when the slide channel selection command is input while the video of the fourth channel CH4 is transferred to the video of the fifth channel CH5, the fourth channel CH4 is selected. It can be recognized that the previous channel (select the previous channel), and the image corresponding to the fourth channel (CH4) is displayed on the screen.

If it is determined in operation 1420 that the slide channel selection command is not input, it may be determined whether the reverse search command is input (1440).

When the reverse search command is input as a result of the determination, the current channel telephone direction can be reversed.

For example, as in the case of FIG. 69, slides in the order of the image of the first channel CH1, the image of the second channel CH2, the image of the third channel CH3, and the image of the fourth channel CH4. When the reverse search command is input while displaying an image, the sequence of the image of the fourth channel CH4, the image of the third channel CH3, the image of the second channel CH2, and the image of the first channel CH1 You can switch the channel switching direction with.

70 to 86 are views for explaining a logon switching method and a multi-logon method. Hereinafter, the description of the parts described in detail above will be omitted.

Referring to FIG. 70, it may be possible for another user to log on in a state where a predetermined user is logged on to the broadcast signal receiver 100Q according to the present invention.

For example, as in the case of FIG. 70, a predetermined first user may log on 1500.

In this case, a menu or an image corresponding to the first user may be displayed 1510 on the display unit 180Q.

Thereafter, in operation 1520, it may be determined whether a second user different from the first user is logged on while the first user is logged on. In this case, a logon switch command may be input.

As a result of the determination, when a logon switching command is input, the logon user may be switched from the first user to the second user different from the first user (1530).

As such, when the logon user is switched from the first user to the second user, the menu or image displayed on the display unit 180Q may be switched to a menu or image corresponding to the second user (1540).

For example, as shown in FIG. 71, when a first user is logged on at a time t1, a logon switch command for a logon of a second user is input at a time t2 when power is not turned off. In this case, the logon user can be switched from the first user to the second user.

Here, the logon switch command for switching the logon user may include a password corresponding to the second user. That is, it may be desirable to input authentication information such as a password for authenticating the second user in order for the second user to log on while the first user is logged on.

If another logon switch command, for example, a second logon switch command, is input while the logon user is switched to the second user, the logon user may be switched from the second user to the first user again. The logon switch command for switching the logon user from the first user to the second user may be referred to as a first logon switch command.

In addition, the second logon switch command may include a password corresponding to the first user similarly to the first logon switch command.

In addition, when the logon user is switched from the second user to the first user, the menu or image displayed on the display unit 180Q may be switched back to a menu or image corresponding to the first user.

As described above, when the second user logs on to the broadcast signal receiver 100Q while the first user is logged on, the screen of the display unit 180Q may also be switched at the logon switching time.

For example, as in the case of FIG. 72A, the first user sets the first to fourth channels CH1 to CH4 as the preferred channel and the fifth to seventh channels CH5 to CH7 as the non-preferred channel. As shown in (B) of FIG. 72, the second user sets the third, fifth, seventh, seventh, and seventh channels CH3, CH5, and CH7 as the preferred channel, and the first, second, and fourth channels, CH1, CH2, and CH4. Assume that) is set to a non-preferred channel.

In this case, when the logon user is switched from the first user to the second user, an image of at least one channel randomly selected from the preferred channels set by the second user may be displayed on the display unit 180Q. That is, an image of at least one channel among the third and fifth to seventh channels CH3 and CH5 to CH7 may be displayed on the display unit 180Q.

Alternatively, as in the case of FIG. 73A, assume that a first user sets sports as a preferred category and a second user sets a movie as a preferred category.

In this case, when the logon user is switched from the first user to the second user, an image of at least one channel randomly selected from among channels corresponding to the preference category set by the second user may be displayed on the display unit 180Q. Can be.

Or, as in the case of FIG. 73 (B), assume that the first user selects the ESPN Sports channel as the setting channel and the second user selects the OCN Movie channel as the setting channel.

In this case, when the logon user is switched from the first user to the second user, an image of the OCN Movie channel, which is a setting channel selected by the second user, may be displayed on the display unit 180Q.

Alternatively, when the logon is switched, the image displayed on the display unit 180Q may be switched according to the preference of the channel.

For example, as shown in FIG. 74, the number of channel selections of the first user is greater than that of the other channels in the third channel CH3 during the predetermined period, and the number of channel selections of the second user is greater than that of the fifth channel CH5. Assume many cases compared to other channels.

In this case, when the logon user is switched from the first user to the second user, the image of the fifth channel CH5 most frequently selected by the second user for a predetermined period of time may be displayed on the display unit 180Q.

Alternatively, the display unit 180Q may display an image of a menu and / or a channel last selected by the switched user when the logon user is switched.

For example, as shown in FIG. 75, when the logon user is switched 1530 from the first user to the second user, the display unit 180Q displays an image of a menu and / or a channel that the second user last selected. May be indicated at 1600. Here, the description overlapping with the foregoing FIG. 70 is omitted.

For example, when the second user is watching the "MBC" channel before logging off, when the logon user is switched from the first user to the second user, the image of the "MBC" channel is displayed on the display unit 180Q. Can be marked on.

Alternatively, for example, when the second user selects the "preferred channel" menu before logging off, the display unit 180Q displays the "preferred channel" menu when the logon user switches from the first user to the second user. Can be marked on.

Thereafter, it is determined whether another logon switch command is input (1560), and when the other logon switch command is input, the logon user is switched from the second user to the first user (1570), and the first user is finally An image of the selected menu and / or channel may be displayed 1610 on the display unit 180Q.

Meanwhile, when the logon user is switched, not only an image and / or a menu but also setting values may be changed.

For example, as shown in FIG. 76, the first user sets the volume to 12, sets the screen mode to the movie mode, the second user sets the volume to 20, and sets the screen mode to the sport mode. Let's assume the case.

In this case, when the logon user is switched from the first user to the second user, the volume may be switched from 12 to 20, and the screen mode may be switched from the movie mode to the sport mode. Of course, the opposite is also possible.

On the other hand, it may be possible to not input authentication information such as a password of each user to switch the logon user.

For example, as shown in FIG. 77, switching keys 1700 and 1710 may be arranged in the wireless input unit 200Q to switch the logon user.

Here, the switch keys 1700 and 1710 may include a first switch key 1700 and a second switch key 1710. The first switch key 1700 may be a key for switching the logon user from another user to the first user, and the second switch key 1710 may be a key for switching the logon user from the other user to the second user.

In this case, the users can switch the logon user only by selecting only the switching keys 1700 and 1710. In addition, various user menus can be used in common without authentication information such as a password.

Alternatively, when switching the logon user, an image of the last channel of the previous user may be recorded. This will be described below with reference to FIGS. 78 to 80. In FIG. 78, a description overlapping with the foregoing FIG. 75 will be omitted.

Referring to FIG. 78, when the logged-on user is switched from the first user to the second user (1530), the user may record an image of the channel that the first user watched last (2000).

For example, when the logon user is switched from the first user to the second user by a logon switch command while the first user is watching the video of the "MBC" channel, the video of the "MBC" channel watched by the first user is fixed. Partial recording is possible.

For example, suppose that the second user logs on using a logon switch command while the first user logs on and watches an image of the first channel CH1 as shown in FIG. 79.

Here, when the first user has finished watching the first half 2100 of the predetermined program at the time of logon switching, the second half 2110 may record the second half 2110 of the program.

In other words, when the logon user switches from the first user to the second user, the remaining portion of the program is recorded when the program of the channel that was first watched by the first user at the time of logon switching is not completed. You can do it.

Alternatively, even when the program of the channel that the previous user was watching at the time of logon switching is not completed, it is possible to determine whether to perform recording in consideration of the degree of program progress at the time of logon switching.

For example, as in the case of FIG. 80, assume that a predetermined first movie starts at time t0 and ends at time t3, that is, when the running time of the first movie is W4.

In such a case, when the logon user is switched to the initial screening times t0 to t1 of the movie, the recording of the story of the movie may be insignificant, and thus recording may not be performed.

In addition, when the logon user is switched to the last part (t2 to t3) of the movie, the movie may be mostly finished, or may not be the cast / step introduction part.

In other words, when the logon user switches from the first user to the second user, when the logon transition time is between the time t1 and the time t1 of the first movie that the first user watched last, the first movie is displayed. The first movie may not be recorded when the video is recorded and the time is between the time t0 and the time t1 and / or between the time t2 and the time t3.

In addition, when the logged-on user is switched from the second user to the first user (1570), the second user may record (2010) the image of the channel that the second user watched.

Alternatively, whether to perform recording may be determined in consideration of the user's preference.

For example, as in the case of FIG. 81, it is determined whether a logon switch command is input (2200). When the determination result is input, it is determined whether the last channel of the previous user is a preferred channel (2210). )can do.

As a result of the determination, when the last channel of the previous user (first user) is the preferred channel, an image of the last channel of the previous user (first user) may be recorded (2220). Here, the preference channel can be set directly by the user.

Alternatively, as in the case of FIG. 82A, it is assumed that the number of times of selecting the first channel CH1 is 120 times and the number of times of selecting the second channel CH2 is three times during a predetermined period. Let's see.

In this case, the first channel CH1 may be a preference channel of the first user, and the second channel CH2 may not be a preference channel of the first user.

Therefore, when the last channel of the first user is the first channel CH1 during logon switching, the video of the first channel CH1 may be recorded. On the other hand, when the last channel of the first user is the second channel CH2 during logon switching, the image of the second channel CH2 may not be recorded.

Or, as in the case of FIG. 82 (B), it is assumed that the watching time of the first channel CH1 of the first user is 1200 hours and the watching time of the second channel CH2 is 40 hours for a predetermined period. Let's see.

In this case, the first channel CH1 may be a preference channel of the first user, and the second channel CH2 may not be a preference channel of the first user.

Therefore, when the last channel of the first user is the first channel CH1 during logon switching, the image of the first channel CH1 may be recorded 2220.

Meanwhile, it may be possible for a plurality of users to log on to different menus.

For example, as shown in FIG. 83, a predetermined first user may log on 1800.

In this case, a menu or an image corresponding to the first user may be displayed 1810 on the display unit 180Q.

Thereafter, in operation 1820, it may be determined whether a second user different from the first user is logged on to another menu while the first user is logged on. In this case, a menu logon switch command may be input. The menu logon switch command input in operation 1820 is called a first menu logon switch command.

Here, the first menu logon switch command may include a password corresponding to the second user.

As a result of the determination, when the first menu logon switch command is input, the logon user of the first menu may be switched from the first user to a second user different from the first user (1830). In this case, the master logon user may be a case where the logon user of a specific menu, for example, the first menu, is switched from the first user to the second user while the first logon user is the first user.

As such, when the logon user of the first menu is switched from the first user to the second user, the first menu may be displayed on the display unit 180Q or the previous menu may be switched to the first menu (1840).

Subsequently, it may be determined whether another menu logon switch command, for example, a second menu logon switch command, is input in the state where the second user is logged on to another menu in the first menu (1850).

As a result of the determination, when the second menu logon switching command is input, the logon user of the second menu may be switched from the first user to a third user different from the first user (1860). In this case, the master logon user may be a case where the logon user of a specific menu, for example, the first menu, is switched from the first user to the third user while the first logon user is the first user.

Here, the second menu logon switch command may include a password corresponding to the third user. Here, the second user may be the same as the third user.

As such, when the logon user of the second menu is switched from the first user to the third user, the second menu may be displayed on the display unit 180Q or the previous menu may be switched to the second menu (1870).

For example, as in the case of FIG. 84, when the first user is logged on at a time t1, the power is not turned off, and the first user for logging on the first menu of the second user at a time t2. When the menu logon switch command is input, the logon user of the first menu can be switched from the first user to the second user.

Here, only the first user may be logged on in the period between the time t1 and the time t2.

If the logon user of the first menu is switched to the second user, when the second menu logon switch command is input, the logon user of the second menu may be switched from the first user to the third user.

Here, the first user and the second user may be logged on in the period between the time t2 and the time t3. Here, the first user may be a master logon user, and the second user may be a sub-logon user.

In addition, after the time t3, the first user, the second user, and the third user may be logged on. Here, the first user may be a master logon user, and the second and third users may be sub-logon users.

In addition, when the logon user is different according to the menu as described above, information on the menu where each logon user logs on may be displayed on the screen.

In other words, when the logon user of the first menu is switched from the first user to the second user, the first menu is additionally displayed while the image of the channel selected by the first user is displayed on the display unit 180Q. It is possible to.

For example, as shown in FIG. 85, the first menu 1910 may be displayed on an image viewed by the first user.

Alternatively, when the logon user of the second menu is switched from the first user to the third user, the third user corresponds to the third user while the image of the channel selected by the first user or the second user is displayed on the display unit 180Q. It is possible to additionally display the second menu or to further display the second menu while the menu selected last by the second user, for example, the first menu, is displayed on the display panel.

For example, as shown in FIG. 86, the first menu 1910 and the second menu 1920 may be displayed together on an image viewed by the first user.

87 to 97 are diagrams for explaining the noise mode. Hereinafter, the description of the parts described in detail above will be omitted.

In the broadcast signal receiver 100Q according to the present invention, the setting may be changed according to noise input from the outside.

In detail, when a noise sound is received through the sound sensing unit, a setting of an audio output from the video or the audio output unit displayed on the display unit may be changed.

Referring to FIG. 87, when the power is turned on 2300, whether a noise sound is received may be determined 2310.

Here, the noise sound may be a sound of a preset frequency band.

For example, as in the case of FIG. 88, a frequency band of 20 Hz or more, that is, a first band, a 3 to 5 Hz frequency band, that is, a second band, a 600 to 800 Hz frequency band, that is, a third band, may be set as a noise sound. Can be.

In this case, when the received sound is included in any one of the first band, the second band, and the third band, the received sound may be determined as a noise sound.

In addition, the noise sound may be a sound having a predetermined pattern.

For example, when a sound having a specific pattern is received as in the case of FIG. 88, the received sound may be determined as a noise sound.

As a result of the determination in operation 2310, when the noise sound is received, it may be determined whether the received noise sound is a first type noise sound.

As a result of the determination, when the received noise sound is the first type noise sound, the setting may be changed (2330) by applying the first changing method.

If it is determined in operation 2320 that the received noise sound is not the first type noise sound, it may be determined whether the received noise sound is the second type noise sound (2340). have.

As a result of the determination, when the received noise sound is the second type noise sound, the setting may be changed (2350) by applying the second changing method.

Herein, the first changing method and the second changing method may have different setting changing methods.

That is, the method of changing the setting of the video or audio when the first type noise sound is received through the sound sensing unit and the method of changing the setting of the video or audio when the second type noise sound is received through the sound sensing unit may be different from each other. will be.

In addition, the type of the first type noise sound and the type of the second type sound may be different from each other.

For example, as in the case of FIG. 89, the first type noise sound may include at least one of a water sound, a vacuum cleaner sound, a preset user voice, for example, a first user voice. Here, the voice of the first user may be a voice of a user whose hearing is deteriorated, for example, a voice of an elderly person.

In addition, the second type noise sound may include at least one of a phone bell sound, a door bell sound, a preset user voice, for example, a voice of a second user.

Here, the voice of the second user may be a voice of a user who has excellent hearing, for example, a voice of a teenager or a child or a crying sound.

The type of the first type noise sound and the type of the second type noise sound may not be limited thereto.

Meanwhile, when the first type noise sound is received through the sound sensing unit, the volume of the voice may be increased.

For example, when a user cleans using a vacuum cleaner while a user watches the broadcast signal receiver according to the present invention, it may be difficult to listen to the sound of the broadcast smoothly due to the noise of the vacuum cleaner. . Accordingly, when the vacuum cleaner noise occurs to increase the volume.

On the other hand, when a predetermined user makes a phone call while watching a broadcast signal receiver according to the present invention, the user who makes a phone call may not have a smooth call due to the sound output from the broadcast signal receiver. Accordingly, the volume is reduced when the ringtone occurs for smooth communication.

As such, by classifying various types of noises into a case of increasing the volume and a case of decreasing the volume, the user can more conveniently use the broadcast signal receiver.

In addition, when the second type noise sound is received through the sound sensing unit, the reproduction of the image may be stopped.

For example, if a guest visits the doorbell while pressing the doorbell while the user views the broadcast signal receiver according to the present invention, the user who is watching may miss the viewing range of the broadcast signal receiver to meet the son. have.

In this case, if the playback of the video being viewed is paused, the video can be continuously viewed without interruption after the guest is picked up.

In addition, when the second type noise sound is received through the sound sensing unit, an image currently being played may be recorded.

In such a case, the video being viewed can be continuously viewed without interruption.

On the other hand, it is possible to vary the amount of change in the volume according to the type of noise noise received.

For example, as in the case of FIG. 90, the increase in volume when the first user's voice is generated among the first type noise sounds may be less than the increase in volume when the sound of water is generated.

In addition, the amount of increase in volume when the vacuum cleaner sound is generated among the first type noise sounds may be greater than the amount of increase in volume when the sound of water is generated.

In this way, the amount of increase in the volume can be varied depending on what kind of first type noise sound is generated.

In addition, although not shown, it may be possible to vary the amount of decrease in volume according to the type of the second type noise sound.

In addition, the amount of increase of the volume may be varied according to the magnitude of the first type noise sound.

For example, as in the case of FIG. 91A, when the generated first type noise sound is relatively small, the amount of increase in the volume of the sound of the audio output can be reduced.

On the other hand, as in the case of FIG. 91 (B), when the magnitude of the generated second type noise sound is relatively large, the amount of increase in the volume of the sound of the audio output can also be increased.

In addition, when the first type noise sound is generated, the audio output of the broadcast signal receiver may be larger than the size of the generated first type noise sound.

91 (A) and (B), it can be seen that the magnitude of the audio output is A1 or B1 larger than the magnitude of the first type noise sound.

In this manner, it is possible to increase the size of the voice differentially according to the size of the first type noise sound.

On the other hand, it is possible to change the setting according to the direction of the user's face (Face). In other words, the image of the image displayed on the display unit or the audio output unit may change the setting of the voice according to the direction of the face detected by the motion sensing unit.

For example, as in the case of FIG. 92A, when the face of the user 2400 faces the display unit 180Q, this may mean that the user's 2400 has a high degree of concentration.

On the other hand, as in the case of (B) of FIG. 92, when the face of the user 2400 does not face the display unit 180Q, it may mean that the concentration of the image of the user 2400 is reduced.

In this case, as in the case of FIG. 93, the luminance (brightness) of the image displayed on the display unit 180Q is reduced, the audio output is reduced, the reproduction of the image is stopped, or the image being reproduced is reduced. You can record.

In the case of FIG. 92B, even if the luminance (brightness) of the image displayed on the display unit 180Q is lowered or the volume of the audio is reduced, the user perceives the luminance of the image and / or the lowered audio output. You may not be able to. In addition, power consumption can be reduced.

In addition, in the case of FIG. 92 (B), a portion that the user cannot view in the frame being viewed may be excessive. Accordingly, when the reproduction of the image is stopped or the image being reproduced is recorded, the missed portion can be viewed later.

In more detail, when the direction of the face of the user 2400 is out of the audiovisual angle of the preset display unit 180Q, the volume of the voice may be reduced.

For example, as in the case of FIG. 94A, when the line perpendicular to the face of the user 2400 is the first line CL, the angle range of 2θ1 around the first line CL is audiovisual. It can be said.

Audio-visual may refer to a range in which the user 2400 may view an image displayed on the display unit 180Q.

If, as in the case of FIG. 94 (B), the user 2400 is out of the audiovisual where the user can watch the image displayed on the display unit 180Q, it may be difficult for the user 2400 to no longer watch the image. Accordingly, the case in which the face of the user faces away from the audio visual angle of the preset display unit 180Q is illustrated in FIG. 94B.

In other words, as in the case of FIG. 95, the second line CL1 and the face of the user 2400 connecting the motion sensing unit 192Q and the user 2400 of the broadcast signal receiver 100Q according to the present invention. When the angle θ2 between the first vertical lines CL is greater than θ1 of FIG. 94, the user 2400 may be regarded as having missed the audiovisual angle.

In this case, the brightness (brightness) of the image displayed on the display unit 180Q may be lowered, the audio output may be lowered, the reproduction of the image may be stopped, or the image being played may be recorded.

Meanwhile, even when a plurality of users watch an image of the broadcast signal receiver 100Q according to the present invention, the luminance (brightness) of the image displayed on the display unit 180Q may be lowered or voiced according to the direction of the face of the users. The output volume can be lowered, the playback of the video can be stopped, or the video being played can be recorded.

In detail, when there are a plurality of users, lowering the brightness (brightness) of the image displayed on the display unit 180Q or outputting audio when the direction of the face of all users is outside the preset audio visual angle of the display unit 180Q. You can lower the volume, stop the playback of the video, or record the video during playback.

Alternatively, when there are a plurality of users, the brightness (brightness) of the image displayed on the display unit 180Q is decreased when the direction of the face of the user, which is greater than or equal to the preset threshold ratio, among the plurality of users is outside the preset audio visual angle of the display panel. In addition, the voice output may be lowered, the playback of the video may be stopped, or the video being played may be recorded.

For example, as in the case of FIG. 97, when the power is turned on 2500 and the number of users is 2510, the broadcast signal receiver 100Q may detect a direction in which the face of each user faces.

For example, as in the case of FIG. 96, assume that the first to fifth users 2410 to 2450 use the broadcast signal receiver 100Q according to the present invention.

In this case, the broadcast signal receiver 100Q according to the present invention can check all of the facial directions of five users.

Thereafter, it may be determined whether all users are outside the audiovisual (2530).

As a result of the determination, when all the users are out of the audiovisual, the setting is changed (2540), for example, the brightness (brightness) of the image displayed on the display unit 180Q is decreased, the audio output (Volume) is reduced, or the reproduction of the image is performed. You can freeze or record the video being played.

On the other hand, as a result of the determination, when at least one user does not leave the audiovisual, it is possible to determine whether the proportion of people outside the audiovisual exceeds the threshold ratio.

As a result of the determination, when the ratio of those who are outside the audiovisual exceeds the threshold ratio, the setting is changed (2540), for example, the luminance (brightness) of the image displayed on the display unit 180Q is reduced, or the volume of the audio is reduced. The playback of the video can be stopped or the video being played can be recorded.

On the other hand, when the determination result, the percentage of people outside the audiovisual is lower than the threshold ratio can be maintained (2560).

For example, if the threshold ratio is 70%, in FIG. 96, if at least two of the total five users are within the audiovisual range, the setting is maintained, and one user is within the audiovisual range or all the audiovisual ranges. If it is out of the, you can change the setting.

Alternatively, a method of changing a setting in consideration of a logged on user among a plurality of users may be possible.

In detail, when there are a plurality of users, a setting may be changed when the direction of the face of the logged-on user among the plurality of users is out of the audiovisual angle of the preset display unit 180Q.

For example, suppose that in FIG. 96, a first user 2410 is a logged-on user and four other users 2420-2450 are not logged on.

In this case, when the first user 2410 is out of the audiovisual level, the luminance (brightness) of the image displayed on the display unit 180Q is lowered regardless of the other four users 2420 to 2450, or the volume is output. You can lower the speed, stop playback of the video, or record the video being played back.

Alternatively, in the case where the first user 2410 is in the audiovisual level, the setting may be maintained even when the remaining four users 2420 to 2450 are all out of the audiovisual level.

98 to 108 are views for explaining the private channel. Hereinafter, the description of the parts described in detail above will be omitted.

In the broadcast signal receiver according to the present invention, at least one of the plurality of channels may be allocated as a personal channel for personal content. Here, the private channel may be a channel to which a broadcast signal is not allocated.

For example, as shown in FIG. 98, the fifth channel CH5 is SBS, the seventh channel CH7 is KBS2, the ninth channel CH7 is KBS1, the eleventh channel CH11 is MBC, and the thirteenth channel (CH13) may be allocated to OBS. Here, all of the fifth to thirteenth channels CH5 to 13 may be channels to which broadcast signals are allocated. Hereinafter, channels to which a broadcast signal is assigned are called general channels.

In addition, a private channel may be allocated to the zeroth channel CH0 in addition to the normal channel. Private content may be allocated to the private channel, and thus, when the viewer selects private content, the private content may be displayed on the display unit 180Q. That is, the private channel may be a channel for displaying / outputting private content.

In other words, an image corresponding to a broadcast signal is displayed on the display unit 180Q in the first channel (general channel) of the plurality of channels, and on the display unit 180Q in the second channel (private channel) of the plurality of channels. Private content can be displayed.

For ease of use, private channels can be selected by entering a channel change command.

In detail, when a channel change command is input from the command input unit, for example, the wireless input unit, an image corresponding to a broadcast signal or a personal content may be displayed on the display unit 180Q in the changed channel. In other words, a channel to which a broadcast signal is assigned or a private channel to which private content is assigned may be selected using a channel change command.

For example, when one of an up channel change command or a down channel change command is input from a command input unit in a first channel (general channel) of a plurality of channels, the first channel (general channel) is different from the first channel (general channel). An image corresponding to a broadcast signal of a channel (general channel) may be displayed on the display unit 180Q.

In addition, when another one of an up channel change command or a down channel change command is input from the command input unit in the first channel (general channel), the private content may be displayed on the display unit 180Q.

For example, as shown in FIG. 99, when a channel up key 210 is input by pressing the channel up key 210 of the wireless input unit while watching the NBTV (CH1), which is a general channel, another general channel is used. The image corresponding to the MTV CH2 may be displayed on the display unit 180Q.

On the other hand, when a user is watching a NBTV (CH1), which is a general channel, and inputs a down channel change command by pressing the channel down key 211 of the wireless input unit, the private channel is changed from another general channel, NBTV (CH1). The channel is switched to the channel CH0, and thus the private content may be displayed on the display unit 180Q.

In other respects, when a user inputs an up-channel change command by pressing the channel up key 210 of the wireless input unit while watching a night movie (CH900), which is a general channel, the private content corresponding to the private channel (CH0) May be displayed on the display unit 180Q. In addition, when the private content corresponding to the private channel CH0 is displayed on the display unit 180Q, when the channel up key 210 is input by pressing the channel up key 210 of the wireless input unit, the general channel NBTV (CH1) is used. The image corresponding to may be displayed on the display unit 180Q. In addition, when inputting a down channel change command by pressing the channel down key 211 of the wireless input unit while the private content corresponding to the private channel CH0 is displayed on the display unit 180Q, Night Movie, which is a normal channel, is again used. An image corresponding to CH900 may be displayed on the display unit 180Q.

The private content may include at least one of electronic mail (e-mail) content, photo content, movie content, music content, text service content, and fax content.

Accordingly, as in the case of FIG. 100, when the private channel CH0 is selected, the e-mail content 2610, the photo content (My Album, 2600 or 2660), and the movie content are displayed on the display unit 180Q. 2620, music content 2630, text service content 2640, and fax content 2650.

In addition, the user can edit the screen configuration of the private channel.

In addition, in order to check e-mail in a private channel, the broadcast signal receiver according to the present invention may have an IP address and receive e-mail from the outside.

Alternatively, the broadcast signal receiver according to the present invention may be connected to an external PC, and in the case where the electronic mail is received by the connected PC, the broadcast signal receiver may be transmitted to the broadcast signal receiver according to the present invention.

In addition, in order to check the text service content 2640 in the private channel, as shown in FIG. 101, the broadcast signal receiver 100Q may communicate with the mobile communication terminal 2700.

In this case, when text is received in the mobile communication terminal 2700, the mobile communication terminal 2700 may transmit the text to the broadcast signal receiver 100Q, and thus the user may transmit the text to the mobile communication terminal 2700 in a private channel. You can check the received text.

In addition, in order to check the fax content 2650 in the private channel, the broadcast signal receiver 100Q may communicate with the fax machine 2710 as in the case of FIG. 101.

In this case, when the fax machine 2710 receives a fax, the fax machine 2710 may transmit the fax to the broadcast signal receiver 100Q, so that the user may receive the fax received by the fax machine 2710 in the private channel. You can check.

Meanwhile, in the private channel, the photo content may be displayed on the display unit 180Q in a slide show manner.

For example, as in the case of FIG. 102, at least one photo content 2660 and 2670 may display a slide show method. In this case, the private channel may be used as a kind of photo album.

In addition, when a new e-mail, a fax, a text, or the like is received, the arrival notification menu 2800 may be displayed on the screen of the display unit 180Q as in the case of FIG. 103.

Alternatively, as in the case of FIG. 103, when new private content is added, a notification unit 2810 may be formed to notify addition of new private content. The notification unit 2810 may be formed at the edge of the display unit 180Q.

On the other hand, considering that the private channel serves as the user's personal album, when a new image is received, it may be possible to display the received image on the screen.

For example, as in the case of FIG. 104, when a message is received 2900, it may be determined 2910 whether an image attachment file exists in the received message.

As a result of the determination, when the message includes the image attachment file, it is determined whether the current channel is a private channel (2920).

As a result of determination, when the current channel is a private channel, the image attachment file may be read 2930 in the message, and the read image may be displayed 2940 on the screen of the display unit 180Q.

In this case, the received image may be displayed on the screen as shown in FIG. 100, regardless of the editing of the user. In FIG. 100, it can be seen that a predetermined image 2660 is displayed on the screen.

In addition, when the image file is extracted from the received message, the image file may be checked using the file extension.

For example, as in the case of FIG. 105, the user may select various extensions corresponding to the image as the image extension.

In this case, the broadcast signal receiver 100Q may search for an attachment having an image extension in a message and display the retrieved image extension file on the screen.

On the other hand, when there are a plurality of users, a plurality of private channels may be set.

For example, as in the case of FIG. 106, the private channel of the first user may be set to CH0-1, the private channel of the second user to CH0-2, and the private channel of the third user to CH0-3. have.

Alternatively, a plurality of users may all use the same channel as a private channel.

For example, as in the case of FIG. 107, the first user, the second user and the third user can all use CH0 as a private channel.

In this case, although multiple users use the same private channel, it is possible to display different private content according to the logged on user in the private channel.

For example, as in the case of FIG. 108, it is determined whether the current channel is a private channel (3000), and if the current channel is the private channel, the determination result determines whether the logon user of the current channel is the first user. 3010.

As a result of the determination, when the logon user of the current channel is the first user, the private channel may display private content according to the first user (3020).

On the other hand, if it is determined that the logon user of the current channel is not the first user, it may be determined whether the logon user of the current channel is the second user (3030).

As a result of the determination, when the logon user of the current channel is the second user, the private channel may display private content according to the second user (3040).

As described above, it is to be understood that the technical structure of the present invention can be embodied in other specific forms without departing from the spirit and essential characteristics of the present invention.
