Accordingly, the demultiplexer 205 filters (PID or section filtering) audio data, video data, and SI data using the PID.

The service discovery manager 210 provides information necessary for selecting a service provider that provides a service. When receiving a channel selection signal from the service manager 213 , the service discovery manager 210 uses the information to find a service.

The service control manager 209 is in charge of service selection and control. For example, the service control manager 209 uses IGMP or RTSP when the user selects a live broadcasting service such as the existing broadcasting method, and selects a service such as VOD (Video on Demand). RTSP is used to select and control services. The RTSP protocol may provide a trick mode for real-time streaming. Also, the service control manager 209 may initialize and manage a session through the IMS gateway 250 using an IP Multimedia Subsystem (IMS) or a Session Initiation Protocol (SIP). The above protocols are only an example, and other protocols may be used according to implementation examples.

The metadata manager 212 manages metadata associated with a service and stores the metadata in the SI&metadata database 211 .

The SI & metadata database 211 selects service information decoded by the SI decoder 204 , metadata managed by the metadata manager 212 , and a service provider provided by the service discovery manager 210 . store the information needed to In addition, the SI&metadata database 211 may store set-up data for the system, and the like. The SI&metadata database 211 may be implemented using a non-volatile memory (NVRAM), a flash memory, or the like.

The controller 325 may detect a user's gesture by individually or in combination with an image captured by a photographing unit (not shown) or a signal sensed from a sensing unit (not shown).

The power supply unit 340 supplies the corresponding power throughout the digital TV. In particular, to supply power to the control unit 325 that can be implemented in the form of a system on chip (SoC), the display unit 380 for displaying an image, and the audio output unit 335 for outputting audio. can To this end, the power supply unit 340 may include a converter (not shown) that converts AC power into DC power. Meanwhile, for example, when the display unit 380 is implemented as a liquid crystal panel including a plurality of backlight lamps, an inverter capable of Pulse Width Modulation (PWM) operation for luminance variable or dimming driving (inverter) (not shown) may be further provided.

The remote control device 345 transmits a user input to the user input interface unit 320 . To this end, the remote control device 345 may use Bluetooth (Bluetooth), Radio Frequency (RF) communication, infrared (IR) communication, Ultra Wideband (UWB), ZigBee method, or the like. In addition, the remote control device 345 may receive an image, audio, or data signal output from the user input interface unit 320 , and display it on the remote control device 345 or output a voice or vibration.

In addition, the digital TV according to the present invention may omit some of the illustrated components as needed or may further include a non-illustrated component. Meanwhile, unlike the above, digital TV does not include a tuner and a demodulator, and may receive and reproduce content through a network interface unit or an external device interface unit.

Referring to FIG. 3B , an example of the controller includes a demultiplexer 350 , an image processor, an OSD generator 366 , a mixer 370 , and a frame rate converter (FRC) 380 . ), and a formatter 390 . In addition, although not shown, the control unit may further include a voice processing unit and a data processing unit.

The demultiplexer 350 demultiplexes the input stream. For example, the demultiplexer 350 may demultiplex the input MPEG-2 TS video, audio, and data signals. Here, the stream signal input to the demultiplexer 350 may be a stream signal output from a tuner or demodulator or an external device interface unit.

The image processing unit performs image processing of the demultiplexed image signal. To this end, the image processing unit may include an image decoder 362 and a scaler 364 . The image decoder 362 decodes the demultiplexed image signal, and the scaler 364 scales the resolution of the decoded image signal to be output on the display unit. The video decoder 362 may support various standards. For example, the video decoder 362 performs the function of an MPEG-2 decoder when the video signal is encoded in the MPEG-2 standard, and when the video signal is encoded in the DMB (Digital Multimedia Broadcasting) method or H.264 standard. In this case, the function of the H.264 decoder may be performed. Meanwhile, the image signal decoded by the image processing unit is input to the mixer 370 .

The OSD generator 366 generates OSD data according to a user input or by itself. For example, the OSD generating unit 366 generates data for displaying various data in the form of graphics or text on the screen of the display unit based on the control signal of the user input interface unit. The generated OSD data includes various data such as a user interface screen of a digital TV, various menu screens, widgets, icons, and viewing rate information. The OSD generator 366 may generate data for displaying broadcast information based on a caption of a broadcast image or an EPG.

The mixer 370 mixes the OSD data generated by the OSD generator 366 and the image signal processed by the image processor, and provides them to the formatter 390 . Since the decoded image signal and the OSD data are mixed, the OSD is overlaid and displayed on the broadcast image or the external input image.

The frame rate converter (FRC) 380 converts a frame rate of an input image. For example, the frame rate converter 380 may convert a frame rate of an input 60Hz image to have a frame rate of, for example, 120Hz or 240Hz according to an output frequency of the display unit. As described above, there may be various methods for converting the frame rate. For example, when the frame rate conversion unit 380 converts the frame rate from 60 Hz to 120 Hz, the same first frame is inserted between the first frame and the second frame, or a second frame predicted from the first frame and the second frame is inserted. It can be converted by inserting 3 frames. As another example, when converting the frame rate from 60 Hz to 240 Hz, the frame rate converter 380 may convert by inserting three more identical frames or predicted frames between existing frames. Meanwhile, when a separate frame conversion is not performed, the frame rate conversion unit 380 may be bypassed.

The formatter 390 changes the output of the input frame rate converter 380 to match the output format of the display unit. For example, the formatter 390 may output R, G, and B data signals, and these R, G, and B data signals are output as a low voltage differential signal (LVDS) or mini-LVDS. can be In addition, when the output of the input frame rate converter 380 is a 3D video signal, the formatter 390 may support the 3D service through the display unit by configuring the output in 3D form to match the output format of the display unit.

Meanwhile, the voice processing unit (not shown) in the control unit may perform voice processing of the demultiplexed voice signal. Such a voice processing unit (not shown) may support processing of various audio formats. As an example, even when the audio signal is encoded in a format such as MPEG-2, MPEG-4, AAC, HE-AAC, AC-3, BSAC, it can be processed with a corresponding decoder. In addition, the voice processing unit (not shown) in the control unit may process a base (Base), a treble (Treble), volume control, and the like. A data processing unit (not shown) in the control unit may perform data processing of the demultiplexed data signal. For example, the data processing unit may decode the demultiplexed data signal even when it is encoded. Here, the encoded data signal may be EPG information including broadcast information such as a start time and an end time of a broadcast program aired on each channel.

Meanwhile, the above-described digital TV is an example according to the present invention, and each component may be integrated, added, or omitted according to the specifications of the actually implemented digital TV. That is, if necessary, two or more components may be combined into one component or one component may be subdivided into two or more components. In addition, the function performed in each block is for explaining an embodiment of the present invention, and the specific operation or device does not limit the scope of the present invention. Meanwhile, the digital TV may be an image signal processing device that performs signal processing of an image stored in the device or an input image.

Hereinafter, various embodiment(s) of a method for processing data in a digital device according to the present invention will be described in more detail with reference to the accompanying drawings.

In particular, various embodiments of a method for performing an operation such as data processing according to a control command of a second digital device in the process of executing an application in a first digital device are disclosed herein according to the present invention.

In relation to this, in this specification, the first digital device is a digital TV as an embodiment, and the second digital device is a mobile terminal as an embodiment. In addition, the mobile terminal includes a smart phone, a wearable device, and the like.

In addition, in the present specification, the control command of the mobile terminal for controlling the digital TV is generated by executing a remote application and touching a GUI (Graphic User Interface) on the executed remote application, and mutually Data communication is performed, but is not limited thereto, and each or any combination or one or the It may be based on a combination of touch, voice, gesture, etc. of the wearable devices.

On the other hand, the remote application executed in the mobile terminal, related to the above-described control command, is a basic application of the mobile terminal or an application installed after downloading, and performs the same or similar function as a remote controller, which is one of the input or control means of the digital TV. application to do it. Therefore, it is not limited to the above names. In addition, although the control command is not necessarily generated and transmitted only through the remote application in the mobile terminal, it will be described as passing through the remote application for convenience.

A data processing method of a digital device according to an embodiment of the present invention includes: receiving a broadcast signal including a broadcast program and signaling data by tuning a specific channel; decoding the broadcast program and signaling data; and the decoded broadcast Displaying a program, receiving a channel change request signal from a first mobile terminal, receiving age information of a user of the first mobile terminal, parsing and storing parental control information from the decoded signaling data; and if it is impossible to switch to the requested channel based on the received age information and the stored viewing restriction information, restricting the change to the requested channel and returning a control command including guide data according to the restriction as a response. steps are included.

In the above, the digital device may output a guide GUI informing that the channel change is restricted according to the request of the first mobile terminal on the broadcast program being displayed.

And, the channel change restriction may include a case of providing the next or previous channel by blocking the corresponding channel or skipping the corresponding channel.

In addition, the method further comprises the step of determining whether to switch the requested channel on the basis of the received age information and the stored parental control information, wherein the determining whether to switch the requested channel is, the first mobile terminal In addition, the step of determining whether the second mobile terminal is connected may be included.

and when the second mobile terminal is connected, receiving the age information of the user of the second mobile terminal, and changing the channel according to the channel change decision according to the channel change request of the first mobile terminal Even if this is possible, it is possible to change to the change requested channel only when it is determined whether the change requested channel can be changed based on the age information of the user of the second mobile terminal.

Further, in the step of limiting the change to the requested channel and returning a control command including guide data according to the restriction as a response, the response may be transmitted to at least one of the first mobile terminal and the pre-stored mobile terminal.

In addition, when the response is transmitted to the previously stored mobile terminal, a request for permission to switch to the channel for which the change is requested and a request for changing the permission setting may be transmitted together with the guide data according to the restriction.

In addition, it may be determined that the first mobile terminal and the second mobile terminal are connected to the digital device only when a remote application for controlling the digital device is executed after pairing with the digital device. .

And the method comprises the steps of generating and storing EPG application data based on the decoded signaling data, receiving the stored EPG application data transmission request from at least one of the first mobile terminal and the second mobile terminal; The method may further include returning a response including the stored EPG application to the mobile terminal in response to the EPG application data transmission request.

In addition, the response according to the returned EPG application transmission request includes a filtered EPG application in which one or more application items are filtered based on the age information of the corresponding mobile terminal user from the stored EPG application data, or The filtered EPG that includes the stored full-EPG application data regardless of the age information of the mobile terminal user, but is filtered based on the age information of the user in the mobile terminal when the full-EPG application data is included in the response You can control the output of application data.

7 is a flowchart illustrating a data processing method according to a control command of a mobile terminal in a digital TV according to an embodiment of the present invention, and FIG. 8 is a diagram described above in a digital TV according to an embodiment of the present invention. 7 is a diagram showing a GUI provided in the data processing process.

7 and 8 relate to processing data according to the control command, in particular when the user sends a control command to control the digital TV based on the age of the mobile terminal user. Meanwhile, in particular, FIG. 7 may be an exemplary embodiment in which the digital TV 720 performs data communication only with the single mobile terminal 710 .

Control for turning on the power of the digital TV 720 when the remote application is executed in the mobile terminal 710 (S702) and the digital TV 720 is powered off A command is transmitted (S704). The mobile terminal 710 and the digital TV 720 may be automatically paired after the digital TV 720 is powered on. Meanwhile, in the above, transmitting a control command for power-on from the mobile terminal 710 to the digital TV 720 before pairing is similar to, for example, transmitting a power-on key signal from the remote controller to the digital TV 720 . can be done in this way.

The digital TV 720 is turned on according to the power-on control command of the mobile terminal (S706). When the digital TV 720 is turned on as described above, the default channel is tuned and the application is decoded from the broadcast signal received through the tuned channel, and the decoded application is provided through the screen (S708). Here, for convenience, in the present specification, when the power of the digital TV 720 is turned on, a preset broadcast channel is tuned and a broadcast program of the corresponding channel is provided as an embodiment, but the present invention is not limited thereto. For example, if there is set content such as executing another application when the digital TV 720 is powered on, the operation may be performed accordingly. Therefore, for convenience, the application will be described herein as a broadcast service application, that is, a broadcast program.

When the digital TV 720 receives the command of the mobile terminal 710 and becomes operable according to the command in step S708, the mobile terminal 710 transmits a control command for a channel change request through the running remote application to the digital TV It transmits to (720) (S710), and also transmits age information of the mobile terminal user (S712).

The digital TV 720 extracts the parental restriction information obtained through the SI data in the broadcast signal according to the channel change control command (S714), and based on the extracted parental control information and the transmitted age information of the user , it is determined whether the change requested channel can be provided, that is, whether the channel can be changed (S716).

As a result of the determination in step S716, if the digital TV 720 cannot change the channel based on the viewing restriction information of the requested channel and the age information of the user of the mobile terminal, the corresponding channel according to the channel change request skips/blocks (S718), and transmits a response (response) to the channel skip or block, that is, a control command, to the mobile terminal (710) (S720). Thereafter, the digital TV 720 waits until the next control command is received from the mobile terminal 710 (S726). Unless specifically mentioned above, even if it is a channel block, it means that a channel skip is also included. The opposite is also true.

When the channel change request is received from the mobile terminal 710 again (S722), the digital TV 720 changes to the corresponding channel when it is determined that the channel can be provided according to the determination result through the above-described processes S714 to S716 (S724) . The digital TV 720 waits until the control command of the mobile terminal 710 is received again (S726).

In the above, the channel change request of the mobile terminal 710 may be made, for example, in two ways. One is a method of requesting a direct change from the current channel to a specific channel according to a channel number input through a numeric key button provided on a remote application, etc., and the other is a method of only requesting a channel provided on the remote application. This is a method of requesting a change to the next channel/previous channel of the current channel according to the channel up/down through the channel up/down key button. The present invention is applicable to both of the above two channel change methods.

In the above, when a channel change request is received from the mobile terminal 710, the digital TV 720 obtains and generates channel map data from a broadcast signal received through a pre-tuned channel as described above and provides information on the channel or program. Reads parental control data. Meanwhile, in FIG. 7 , it has been described that the mobile terminal 710 transmits user age information together with the transmission of a control command for changing a channel. In this case, the user's age information may be continuously and repeatedly provided when a control command for changing each channel is transmitted, or the user's age information may be transmitted only once for the first time after the remote application is executed and then transmitted only when a special request is made. have. In addition, the mobile terminal 710 may transmit the user's age information only when requested by the digital TV 720 rather than first transmitting the user's age information simultaneously or sequentially with the transmission of the channel change control command. When the user's age information is requested, the digital TV 720 determines whether there is user's age information pre-stored for the mobile terminal, and as a result of the determination, there is no pre-stored user's age information or a channel that needs to be checked again. You can request the user's age information only in the case of conversion, etc. Here, the SI data refers to the content described above in FIG. 2 .

In the case where it is impossible to switch to the requested channel as a result of the determination according to the channel change request of the mobile terminal 710 , the digital TV 720 blocks the corresponding channel. In this case, the digital TV 720 may process as in any one of FIGS. 8B to 8D, and the mobile terminal 710 may notify the user that the corresponding channel is blocked as shown in FIG. 8A.

Referring to FIG. 8A , the mobile terminal 710 has a GUI 810 for guiding that the channel is blocked based on the data according to the channel unavailable for the change request of the digital TV 720, and permission setting is required for use. provides

In FIG. 8B , when it is determined that the corresponding channel cannot be provided as a result of the determination in step S716 in the digital TV 720, the EPG application 820 is executed and provided on the screen. In this case, the executed EPG application may output filtered EPG data based on the age information of the user for the convenience of using the digital TV 720 , such as changing a channel using the remote application of the mobile terminal user. In other words, the EPG data provides an EPG screen on which applications that are not accessible to the user are displayed based on the user's age information, so that the user does not experience the inconvenience of changing a channel, and the digital TV 720 according to the iterative decision process efficiency can be improved. Meanwhile, the EPG data may be displayed so that a channel requested by the user can be identified.

In FIG. 8C , the digital TV 710 provides a first GUI including the channel number, program information, and broadcasting station information for the channel requested by the user in the first area 832 on a black screen, and the second area 834 ) indicates that the corresponding channel is blocked and provides a second UGI instructing to reset the authority for use.

In FIG. 8D, unlike FIG. 8C described above, the digital TV 710 provides the next or previous channel instead of the corresponding channel in response to the channel change request of the mobile terminal 710, and a predetermined area on the screen for providing the next or previous channel. At 844, the corresponding channel has been blocked, and a guide GUI is provided to reset the authority to use it. In this case, the digital TV 710 provides the channel number, program information, broadcasting station information, etc. for the next or previous channel to the first area 842, and provides a program execution screen of the next or previous channel on the screen.

Meanwhile, when the guide GUIs 834 and 844 are selected, although not shown, a GUI for resetting the use authority may be provided. For example, a GUI for delivering a permission request message to the parent, resetting permission, or inputting a password for permission authentication, etc. may be provided.

9 is a flowchart illustrating a data processing method according to a control command of a mobile terminal in a digital TV according to another embodiment of the present invention.

9 is similar to the above-mentioned FIG. 7, but unlike FIG. 7, when the digital TV 920 is paired with a plurality of mobile terminals instead of one mobile terminal 910 to perform data communication, according to the present invention, one or A process of processing data according to a control command received from the mobile terminal will be described.

Hereinafter, descriptions of the same or similar parts as those of FIG. 7 will be omitted or briefly described, and different parts will be mainly described. For example, referring to FIG. 9 , steps S902 to S926 are substantially the same as steps S702 to S720 of FIG. 7 described above. However, the remote application execution process of the second mobile terminal 930 (S904), the age information of the second mobile terminal user is transmitted (S916), and the control command is transmitted according to the channel block of the digital TV 920 (S926) Only more steps were added. In the above, the remote application execution step of the second mobile terminal 930 is not necessarily limited to the illustrated step, and the user age information needs to be simultaneously performed when the user age information of the first mobile terminal is transmitted, as shown in FIG. 7 above. there is no Meanwhile, the second mobile terminal 930 may perform data communication with the digital TV 920 directly or through the first mobile terminal 910 . Therefore, it is not limited to the illustrated flow or data communication direction.

Referring to FIG. 9 , if it is determined that a change to the corresponding channel is possible according to the channel change request (S912) of the first mobile terminal 910 (S920), the digital TV 920 even sends the channel change request. 1 It is further determined whether the corresponding channel can be provided based on the age information of the user of the second mobile terminal 930 that is received from the first mobile terminal 910 but is paired and the remote application is running ( S928 ). At this time, the digital TV 920 excludes only the paired mobile terminal and determines whether the viewing restriction in step S928 is limited to only the mobile terminals in which the remote application is running after the pairing, that is, whether to provide the channel requested to be changed. can

As a result of the determination in step S928, the digital TV 920 determines that if the user of the first mobile terminal can view the requested channel, but the user of the second mobile terminal cannot view the requested channel based on the user's age information, etc. , blocks the provision of the corresponding channel and transmits a response according to the aforementioned channel block, that is, a control command, to the first mobile terminal 910 and/or the second mobile terminal 930 .

Thereafter, steps S930 to S936 are substantially the same as steps S722 to S726 of FIG. 7 described above. However, the channel change request in step S930 is only performed by the second mobile terminal 930 instead of the first mobile terminal 910 .

Meanwhile, although steps S920 and S928 have been separately described above, the present invention is not necessarily limited thereto. In other words, as described above, with respect to all the mobile terminals that are paired and the remote application is running, it can be determined at once in step S920. However, when a determination is made on whether to provide a change-requested channel based on age information of users of a plurality of mobile terminals at a time, the corresponding channel may be blocked by at least one mobile terminal user, or It may not be. For example, as a result of determining based on the age information of three mobile terminal users, if the corresponding channel is blocked due to the age of one mobile terminal user, there may be inconvenience in changing the channel, etc., and it may not conform to the intentions of the users. Therefore, when it is determined based on the age information of all mobile terminal users as a result of judging whether to provide a channel or not, if even one does not satisfy the above-mentioned conditions, a guide GUI for resolving the problem is displayed on the digital TV and the corresponding mobile terminal or all mobile terminals. can be provided to

10 is a flowchart illustrating a data processing method according to a control command of a mobile terminal in a digital TV according to another embodiment of the present invention.

If it is assumed that the second mobile terminal 930 of FIG. 9 is paired with a digital TV together with or at the same time as the first mobile terminal 910 and a remote application is executed, in contrast to this, FIG. When only the mobile terminal 1010 performs data communication with the digital TV, it can be seen that the second mobile terminal 1030 is newly added in the middle. In the second mobile terminal 1030 , pairing and remote application may be executed at the addition time point, or it may be considered as a case in which pairing was performed before that time, but the remote application was executed at the addition time point.

Hereinafter, as described above, in the description of FIG. 10 , the description of the same or similar parts as those of FIGS. 7 and 9 will be cited or applied mutatis mutandis, and different parts will be mainly described.

For example, steps S1002 to S1024 between the first mobile terminal 1010 and the digital TV 1020 are substantially the same as steps S702 to S724 of FIG. 7 described above. Therefore, for the detailed description thereof, the description of FIG. 7 mentioned above is used or applied mutatis mutandis, and detailed description thereof will be omitted.

After performing step S1024, the digital TV 1020 waits until the next control command is received from the mobile terminal. At this time, when the control command, for example, the channel change request (S1030, 1032) is received, steps S1034 to S1042 are performed. Here, steps S1034 to S1042 are, for example, substantially the same as steps S1016 to S1024 or steps S920 to S928 of FIG. 9 described above.

The steps S1034 to S1042 are not necessarily performed sequentially. In other words, only when the second mobile terminal 1030 is paired with or prior to receiving an additional channel change request from the first mobile terminal 1010 in step S1032, and the remote application is executed (S1026), If step S1042 is performed and not, step S0142 may not be performed like steps S1016 to S1024. Meanwhile, in this process, the second mobile terminal 1030 may transmit the user's age information to the digital TV 1020 directly via the first mobile terminal 1010 ( S1028 ).

According to the determination result of step S1042, the digital TV 1020 performs the process after step S0136 or switches to step S0148, that is, the channel requested to be changed (S1048).

After performing the step S0148, the digital TV 1020 enters the waiting state for receiving the next control command as described above (S1050). Referring to FIG. 10 , when the channel change ( S1444 ) of the first mobile terminal 1010 or the channel change ( S1446 ) of the second mobile terminal 1030 is received, steps S1034 to S1048 are performed again. However, when the remote application of any one of the first and second mobile terminals 1010 and 1030 is terminated or the pairing is released, the digital TV 1020 performs steps S1016 to S1024 instead of the steps S1034 to S1048 described above. do.

On the other hand, when a control command is simultaneously received from the first and second mobile terminals 1010 and 1030 of the digital TV 1020, processing thereof is problematic. In this case, the digital TV 1020 first determines the properties of the control commands received from the first and second mobile terminals 1010 and 1030 . As a result of the determination, if the properties of each control command overlap, it is sufficient to recognize only the control command received from any one mobile terminal and respond accordingly. However, when the respective control commands have conflicting attributes, a mobile terminal having a higher priority among the first and second mobile terminals 1010 and 1030 or a mobile terminal paired first and executing a remote application, and a mobile terminal having a greater signal strength At least one of the age or sex of the mobile terminal user in relation to the terminal and the application, the location, direction or distance between the digital TV and the mobile terminal, and the relationship between the control command and the application, etc. It is possible to select one mobile terminal based on , and operate according to a control command of the selected mobile terminal. In addition, when the digital TV 1020 receives control commands sequentially from each mobile terminal within a predetermined time period, the digital TV 1020 may process as follows. First, when a control command is continuously received from the same mobile terminal, the digital TV 1020 may operate according to the control command received later. It could be the other way around. On the other hand, when the control commands are continuously received from different mobile terminals within a predetermined time period, the digital TV 1020 is the same through the distance of each mobile terminal and the location, direction or distance between each mobile terminal and the digital TV. In the case of being made within a range recognized as a space, the former control command has priority, but it may be the other way around. In addition, when each mobile terminal is located in a different space, a control command received from a mobile terminal recognized as being in the same space as the digital TV or having a relatively closer distance among the mobile terminals may be given priority. Meanwhile, when each event occurs, the digital TV may transmit a control command to output a guide GUI or a status GUI to connected mobile terminals.

11 is a flowchart illustrating a data processing method according to a control command of a mobile terminal in a digital TV according to another embodiment of the present invention.

11 illustrates a process in which a control command is transmitted to control the digital TV 1120 through the second mobile terminal 1130 , and the digital TV 1120 processes and operates data according to the transmitted control command. In this case, in the case where the second mobile terminal user is, for example, a child, a processing method for the case where parental permission is required in the process of controlling the digital TV 1120 will be described in detail herein.

Here, the entire process of FIG. 11 is substantially the same as the process of FIG. 7 , except for steps S1102 and S1124 to S1128 . Accordingly, the detailed description of the steps other than the above steps will be described with reference to or mutatis mutandis the description of FIG.

As described above, it is assumed that the user of the first mobile terminal 1110 is a parent and the user of the second mobile terminal 1130 is a child.

The first mobile terminal 1110 transmits the user (parent) to the digital TV 1120 when the user (parent) sets the authority of the second mobile terminal 1130 by executing a remote application or the like (S1102). In this case, the first mobile terminal 1110 may transmit the settings to the second mobile terminal 1130 . Meanwhile, the setting items may include all of various setting items such as parental restriction setting, viewing time setting, application property or type (type) setting. In addition, although it has been described that the control command including the setting items of the first mobile terminal 1110 to the digital TV 1120 is transmitted before the execution of the remote application of the second mobile terminal 1130 in step S1102, limited to this doesn't happen In other words, the first mobile terminal 1110 may transmit the setting items to the digital TV 1120 at any stage or may not transmit it at all. In the latter case, the phone number of the first mobile terminal 1110 is registered in the digital TV 1120, and as in step S1120, when a channel block is required, permission setting or permission is requested ( In the case of S1124), a control command such as setting or setting change or permission may be transmitted (S1126).

When a control command such as channel change permission or permission setting change is received from the first mobile terminal (S1126), the digital TV 1120 parses the control command to determine whether the channel change, etc. is permitted (S1128), and sets the channel It can be changed (S1130). And the digital TV 1120 waits again.

12 is a diagram illustrating a GUI provided in a data processing process in the digital TV according to FIGS. 9 to 11 according to an embodiment of the present invention.

Fig. 12A illustrates a first mobile terminal and Fig. 12B illustrates a second mobile terminal, and it is assumed that each mobile terminal is running a remote application. Alternatively, the first mobile terminal user may be a parent, and the second terminal user may be a child. Or vice versa.

As described above, when the requested channel is blocked due to all or any one of the mobile terminals in response to the channel change request of the first mobile terminal of FIG. 12A or the second mobile terminal of FIG. 12B, as described above. As shown in FIG. 12, the digital TV may output a GUI guiding the current state as shown in FIGS. 12C to 12E separately from the transmission of the control command.

Referring to FIG. 12C , the digital TV provides a channel bar providing channel, program, and broadcasting station information in a first area 1210, and a GUI informing that the corresponding channel is blocked and permission setting change is provided in the second area 1220. In addition, in the third area 1230 , a GUI notifying or selectable of switching to the next or previous channel according to the channel skip may be provided.

Referring to FIG. 12D , the digital TV displays a channel bar in the first area 1240 , and informs that a new terminal is paired in the second area 1250 , and that a channel change request is received from the new terminal in the third area 1260 . output the GUI. FIG. 12D may be viewed as an example of a guide GUI provided in FIGS. 9 or 10 , for example.

Referring to FIG. 12E , the digital TV provides a GUI for guiding that a channel bar is drawn in a first area 1270 and a channel block of a requested channel is released and can be viewed in a second area 1280 . FIG. 12D can be viewed as a GUI for a case where, as a result of the determination in step S1128 in FIG. 11 , the parent permits the release of the channel block for the corresponding channel and the channel block for the corresponding channel is released.

13 is a flowchart illustrating a method for processing EPG application data between a digital TV and a mobile terminal according to an embodiment of the present invention, and FIG. 14 is a flowchart illustrating EPG application data processing between a digital TV and a mobile terminal according to another embodiment of the present invention FIG. 15 is a flowchart illustrating a method, and FIG. 15 is a diagram illustrating an EPG application data GUI provided by a digital TV and a mobile terminal according to FIGS. 13 to 14 according to an embodiment of the present invention.

13 and 14 both relate to an embodiment of processing EPG application data in a digital TV in response to a request of a mobile terminal. However, whereas FIG. 13 provides EPG application data filtered according to the mobile terminal user in the digital TV, FIG. 14 provides the full EPG application data regardless of the mobile terminal user in the digital TV and EPG filtered by the mobile terminal itself There is a difference in providing application data.

First, referring to FIG. 13 , the mobile terminal 1310 executes a remote application ( S1302 ) and requests to turn on the power of the digital TV ( S1304 ).

When the digital TV 1320 is turned on according to the power-on request of the mobile terminal 1310 (S1306), it provides a broadcast program by tuning a default channel (S1308), and a broadcast signal received through the tuned channel Decodes the SI data from the EPG application data is generated and stored (S1310).

Then, when the digital TV 1320 receives the age information of the mobile terminal user and the EPG application data request from the mobile terminal 1310 (S1312/S1314), the digital TV 1320 filters the EPG application data stored in advance based on the age information to filter the age information. Filtered EPG application data including only the viewable application list is generated and transmitted to the mobile terminal 1310 (S1316).

The mobile terminal 1310 outputs the filtered EPG application data received from the digital TV 1320 as it is on the screen as shown in FIG. 15A (S1318).

On the other hand, referring to FIG. 14 , steps S1402 to S1414 are the same as steps S1302 to S1314 of FIG. 13 described above. However, in FIG. 14 , the pre-stored full-EPG application data is transmitted to the mobile terminal 1310 according to the EPG application request of the mobile terminal 1310 in step S1414 regardless of the age information of the mobile terminal user (S1416) .

The mobile terminal 1310 filters the full-EPG application data received from the digital TV 1320 based on the age information of the mobile terminal user (S1418), and outputs the filtered EPG application data as shown in FIG. 15A ( S1420).

Therefore, as shown in FIG. 14 , when the digital TV 1320 transmits the full-EPG application according to the request of the mobile terminal, there is no need to receive the user's age information in step S1412 . Therefore, the corresponding step can be skipped.

Meanwhile, in FIGS. 13 and 14 , it is said that the mobile terminal 1310 outputs the filtered EPG application data as shown in FIG. 15A. It may be output together with a viewable application item such as full-EPG, but may be provided differentiated, such as highlighted or different in color, or provided without differentiation, but to indicate that viewing is restricted when the corresponding application item is selected can also be processed.

Meanwhile, when the mobile terminal outputs the filtered EPG application data as shown in FIG. 15A , the digital TV 1320 may also output the EPG application data as shown in FIG. 15B . The output of the EPG application data of the digital TV 1320 may be provided only when the user of the mobile terminal can also effectively watch the digital TV 1320 when referring to the location, direction, distance, etc. of the mobile terminal. On the other hand, the digital TV 1320 may provide pre-stored full-EPG application data when providing EPG application data, as shown in FIG. 15B , and may provide the same filtered EPG application data as the mobile terminal 1310 . may be
