For example, the frame rate converter 380 may convert the frame rate of the input 60Hz image to have a frame rate of, for example, 120Hz or 240Hz according to the output frequency of the display unit. As described above, various methods may exist in the method of converting the frame rate. For example, when the frame rate converter 380 converts the frame rate from 60 Hz to 120 Hz, the frame rate converter 380 inserts the same first frame between the first frame and the second frame or predicts the first frame from the first frame and the second frame. It can be converted by inserting three frames. As another example, when converting the frame rate from 60Hz to 240Hz, the frame rate converter 380 may insert and convert three more identical frames or predicted frames between existing frames. Meanwhile, when no separate frame conversion is performed, the frame rate converter 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 the R, G, and B data signals may be output as low voltage differential signals (LVDSs) or mini-LVDSs. Can be. In addition, if the output of the input frame rate converter 380 is a 3D video signal, the formatter 390 may support a 3D service through the display by configuring the output in a 3D form according to the output format of the display.

The voice processor (not shown) may support processing of various audio formats. For example, even when a voice signal is encoded in a format such as MPEG-2, MPEG-4, AAC, HE-AAC, AC-3, BSAC, etc., a decoder corresponding thereto may be provided. Also, the voice processing unit (not shown) in the controller may process base, treble, volume control, and the like. The data processor in the control unit (not shown) may perform data processing of the demultiplexed data signal. For example, the data processor 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 broadcasted in each channel.

In the following description, a digital device is a digital TV and an external device is a mobile terminal.

In particular, the present invention relates to processing when a call connection request (incoming call) is received by a mobile terminal paired with the digital TV while the user is using the digital TV. The present invention can be applied not only to the incoming call but also to the outgoing call.

The use of a digital TV by a user includes not only a case of using a TV service including a broadcast service (for example, watching) but also sharing a screen of a mobile terminal in the digital TV. There is a same or similar method such as mirroring, Miracast, DLNA, etc. with respect to a method of sharing the screen of the mobile terminal in the digital device, which will be described as mirroring for convenience. Accordingly, the digital TV receives mirroring data from the mobile terminal, processes it, and outputs the mirroring data on the screen.

Incoming and outgoing calls of the mobile terminal can be made through a call application. Here, the call application may include both a voice call dedicated application and a video call application.

According to the present invention, when a user calls to or transmits through the mobile terminal while using a TV service or a screen sharing service of the mobile terminal through digital TV, the processing will be described in detail. Herein, the present invention describes a case where a call is made through a digital TV, instead of a call through the mobile terminal. However, hereinafter, for the convenience of explanation and convenience of description, the case of incoming call will be described as an example. However, the present invention is not limited to the incoming call but can also be applied to the outgoing call.

7 is a diagram illustrating a mobile terminal for transmitting mirroring data to the digital TV according to a digital TV and a Miracast scheme.

The digital TV 710 and the mobile terminal 720 may be paired with each other, and may perform data communication according to various communication protocols after the pairing. Here, the digital TV 710 and the mobile terminal 720 may be, for example, devices belonging to the same network, but are not necessarily limited thereto.

The digital TV 710 outputs various services such as a TV service and a mirroring service through a screen and a speaker. In this case, the digital TV 710 receives and outputs mirroring data of the mobile terminal 720 to share the screen of the mobile terminal 720, that is, the screen of the mobile terminal 720 on the digital TV 710. It can provide the same screen as. In this embodiment, the mirroring data is transmitted / received to each other based on Wi-Fi Direct. Therefore, the digital TV 710 may receive at least one of video, image, audio data, etc. for screen sharing of the mobile terminal 720 based on the Wi-Fi Direct. In the above, if only audio data is included as the mirroring data, the digital TV 710 may use a communication protocol such as Bluetooth instead of the Wi-Fi Direct. As will be described later, in connection with the present invention, call application data may be transmitted / received to each other based on a communication protocol identical or different to the mirroring data.

The following describes the processing when the digital TV is processing the mirroring data of the mobile terminal first, when a call of the mobile terminal, that is, an incoming / outgoing call (or a call application is executed).

8 to 10 are diagrams illustrating a data processing process when the mobile terminal is received by the mobile terminal during mirroring data processing of the mobile terminal in the digital TV according to one embodiment of the present invention.

8 is a flowchart of the data processing process, FIG. 9 is a block diagram of a digital TV processing mirroring data of a mobile terminal, and FIG. 10 is a digital TV when the mobile terminal is received during the mirroring data processing. FIG. 710 is a diagram illustrating a UI / UX related to providing guide data informing of an incoming call.

A method of processing data of a mobile terminal in a digital device includes: pairing with the mobile terminal, receiving mirroring data from the mobile terminal using a first communication protocol, outputting the received mirroring data on a screen, and Receiving guide data according to an incoming call detection from a mobile terminal, activating a second communication protocol for a call service, and receiving first call application data about a caller from the mobile terminal according to the first communication protocol; A third call about the called party, which receives and outputs second call application data about the caller according to the activated second communication protocol, and is received through an input means connected to the digital device according to the second communication protocol. Application data It can comprise the step of transmitting to the mobile terminal.

The method may further include demultiplexing the received first call application data, and video data of the caller of the demultiplexed first call application data performs video decoding, and voice data does not perform audio decoding. It may further include.

Acquiring video data of the called party through a camera sensor; outputting the obtained video data of the called party together with the received first call application data to the mobile terminal according to the first communication protocol. The method may further include transmitting. The method may further include determining whether there is video data of a called party acquired through a camera sensor, and if there is no video data of the called party as a result of the determination, outputting preset replacement image data together with the first call application data, The method may further include transmitting to the mobile terminal according to a communication protocol.

Determining whether a time stamp exists from first call application data and second call application data relating to a caller; and if the time stamp exists as a result of the determination, the first call application and the second call application according to the time stamp. The method may further include outputting a sync of the call application. If there is no time stamp as a result of the determination, the first call application and the second application to be decoded may be immediately output without delay.

Meanwhile, at least one of the second call application data and the third call application data received according to the second communication protocol may include noise reduction, auto gain control, and acoustic echo cancellation. At least one of echo cancellation processing and volume reduction may be performed.

In addition, the digital device may be any one of a digital TV and a wearable device, and the input unit may be one of a remote controller and a wearable device connected to the digital TV.

The method may further include outputting guide data received from the mobile terminal to a predetermined area on the screen, and receiving a user's selection from the output guide data.

The received first call application data may be output through any one of the front screen, a picture in picture (PIP) window, and a screen split window.

The digital TV 710 pairs with the mobile terminal 720 (S802). Here, the pairing may be made according to a known technique. Therefore, detailed description of the pairing is omitted herein.

After pairing through the step S802, the digital TV 710 receives mirroring data from the mobile terminal 720 (S804). Here, in step S804, a process such as a Miracast request / response may be performed first for sharing the screen of the mobile terminal 720 before the mirroring data transmission / reception.

The digital TV 710 processes and outputs mirroring data received from the mobile terminal 720 (S806). Herein, the processing refers to data processing for outputting the mirroring data through the digital TV 710 and refers to overall data processing such as decoding. Accordingly, the user can watch the same screen as the screen of the mobile terminal 720 on the large screen of the digital TV 710.

Here, the above-described mirroring data of steps S804 and S806 may be transmitted / received through at least one communication protocol of FIG. 9 and Wi-Fi Direct, Bluetooth, and the like. Referring to FIG. 9, the digital TV 710 transmits mirroring data in the form of a transport stream (TS) (hereinafter referred to as a mirroring TS) in which audio data and video data are muxed according to the Wi-Fi Direct communication protocol. May be received from 720.

In the digital TV 710, the receiving unit 910 for receiving the mirroring TS and the mirroring TS received through the receiving unit 910 are demultiplexed into audio data and video data by the demultiplexer 920. The demultiplexed video data is sent to the video decoder 930 for decoding, and the demultiplexed audio data is sent to the audio decoder 940 for decoding. The video data and the audio data decoded by the respective decoders are output through the screen and the speaker in synchronization with each other. In FIG. 9, the digital TV shows and describes only a configuration essential for processing the mirroring TS for convenience, but another configuration may be further included or used with reference to FIGS. 2 and 3 to process the mirroring TS. Meanwhile, when the video data and the audio data in the mirroring TS are encoded in a format different from that of the TV service data, the video decoder 930 and the audio decoder 940 may decode by a decoding method corresponding thereto. In addition, although the receiver 910 has been described in the form of one module, the receiver 910 may include a receiver (not shown) for receiving mirroring data and a receiver (not shown) for receiving call application data, respectively, as separate modules. This is, for example, to receive / process the data when the mirroring data and the call application data are transmitted / received through different communication protocols.

As described above, when an incoming call (call connection request) is detected to the mobile terminal 720 while providing the mirroring service in the digital TV 710 through the step S806 (S808), the mobile terminal detects the detected incoming fact. The first call application data including the guide data, that is, the incoming guide data, is transmitted to the digital TV 710 in order to notify the user of the present invention (S810). Here, the first call application data may be transmitted according to the Wi-Fi Direct communication protocol described above, but is not limited thereto. When the first call application data is received from the mobile terminal 720, the digital TV 710 reads the incoming call guide data 1010 from the received first call application data and processes it as shown in FIG. Has come. Do you want to connect? (Y / N) ”is output on the screen (S812).

When the user allows the incoming call on the digital TV 710 through the guide data, the digital TV 710 requests call application data and provides the incoming call service through the digital TV according to the response of the mobile terminal 720. . In this case, when the video / audio call application on the mobile terminal 720 is used on the digital TV 710, a problem may occur in processing of audio or voice data. For example, when a call application is executed on the mobile terminal 720, a speaker and a microphone of the mobile terminal 720 which are turned off for a mirroring service are automatically turned on, and voice data of a caller is output through the speaker. The receiver's voice data is input through the microphone. However, if the user does not have the mobile terminal 720, it is difficult to check the caller's voice data through the speaker of the mobile terminal 720, and inputs the caller's voice data through the microphone of the mobile terminal 720. There is a problem that is difficult to deliver. That is, in the above case, there is a problem in that a call is connected and it is difficult to properly use a call service. In addition, the conventional mobile terminal 720, when a call application is executed according to the incoming (call connection) during the mirroring service, as described above, not the speaker of the digital TV 710, but the speaker of the mobile terminal 720 itself. This is because it is common to utilize a microphone and a mobile terminal 720, and the digital TV 710 cannot determine whether a microphone device is provided in the mobile terminal 720, and the digital TV 710 also does not support the function of Bluetooth.

In order to solve this problem, in the present invention, when an incoming call is detected in the mobile terminal 720, the digital TV 710 and the mobile terminal 720 are automatically connected by activating the Bluetooth communication protocol. As such, when the digital TV 710 and the mobile terminal 720 are automatically connected through the Bluetooth, the mobile terminal 720 recognizes the digital TV 710 as a Bluetooth headset and turns off a speaker. The digital TV 710 recognizes the mobile terminal 720 as an audio input / output device. In this case, the caller's voice data is output through the speaker of the digital TV 710, and the caller's voice data is transmitted to the mobile terminal through, for example, a TV microphone, a remote controller microphone, or a microphone of a wearable device. The call service can be used. Meanwhile, as described above, the call service through the Bluetooth connection may be used regardless of the mirroring service between the digital TV 710 and the mobile terminal 720.

Meanwhile, in the present invention, in relation to the Bluetooth function, it is assumed that the digital TV 710 supports various profiles related to HSP (Head Set Profile), HFP (Hands Free Profile) function, etc. of the Bluetooth standard. For a detailed description of the Bluetooth standard and the profiles, refer to the contents defined and disclosed in the standard, which will be omitted.

In step S812, after the digital TV 710 outputs the reception guide data of the mobile terminal as shown in FIG. 10B, when the user allows the incoming call through the digital TV 710 through a remote controller or the like, the digital TV 710 may include the following. The second call application data is requested (S814). Here, the second call application data includes, for example, voice data of the caller in the case of a voice call, and image / video and voice data of the caller in the case of a video call.

When the second call application data request of step S814 is received, the mobile terminal 720 activates a Bluetooth connection with the digital TV 710 to transmit the requested second call application data (S816).

When the digital connection between the digital TV 710 and the mobile terminal 720 is activated through the step S816, the mobile terminal 720 transmits the requested second call application data to the digital TV 710 ( S818).

In operation S818, the digital TV 710 receives the second call application data from the mobile terminal 720, processes the same, and outputs the same through the screen and / or the speaker (S820). Accordingly, the called party (user) may use the voice / video call service of the mobile terminal 720 even during the mirroring service through the digital TV 710 (S820).

Thereafter, the digital TV 710 transmits a control command to the mobile terminal 720 according to the receiver's input (S822), and the mobile terminal 720 responds corresponding to the control command (S824).

The control command may include content of all the controls that the called party can make while using the call service of the mobile terminal 720 in the digital TV 710. The digital TV 710 may generate and provide a UI / UX related to the control command on a screen in order to receive the control command. Therefore, the called party (user) can have the same experience as using the call service on the mobile terminal while using the call service of the mobile terminal through the digital TV. For example, in the case of a video call service, it is possible to control the image resolution, image size, image output position of the caller and the called party, and also adjust the volume of the caller and the called party. Controllable by accessing UX. In addition, it is possible to switch between a voice call and a video call during a call, and the call service can be terminated through the call termination UI. In this case, the mobile terminal may also terminate the call, and at this time, may release or continue the Bluetooth connection connected for the call service. Even when the Bluetooth connection is continued as in the latter case, if the call service is not used for a predetermined time or when the battery level of the mobile terminal is lower than a predetermined range, the connection may be released.

11 is a diagram illustrating a method for processing call application data in a digital TV connected to a mobile terminal according to one embodiment of the present invention.

In FIG. 11B, the digital TV may provide the same screen as the call application screen of the mobile terminal of FIG. 11A. In this case, as shown in FIG. 11B, call application data on the mobile terminal may be provided through the entire screen 1110 of the digital TV.

Referring to FIG. 11C, mirroring data or TV service data is output on the screen 1120, and the call application data is PIP (on the window 1130 provided in the area A and / or the window 1135 provided in the area B). Picture in Picture). If the above-mentioned output is made on only one of the A region window 1130 or the B region window 1135 of the digital TV, the image of the called party may not be provided and only the caller's image may be output. However, if both A area window 1130 and B area window 1135 are provided for a call application, the caller's image may be provided on one of the windows and the caller's image on the other. Meanwhile, various key button UIs for using a call application, controlling, etc. may be provided in the corresponding area. Meanwhile, positions, sizes, and the like of the A region 1130 and the B region 1135 may be arbitrarily adjusted. For example, the window in which the caller's image is output may be the same size or larger than the window in which the caller's image is output.

Meanwhile, referring to FIG. 11D, the digital TV divides the screen into two and continuously provides mirroring data or TV service data on the first divided window as before, and provides call application data received from the mobile terminal on the second divided window. Can provide. Mirroring data or TV service data provided on the first split window may be reconfigured to fit the window size according to, for example, a screen reconstruction.

On the other hand, as shown in FIG. 11B, when the call application data is provided through the front of the screen of the digital TV, the mirroring data or the TV service data is switched to the background, and the playback stop, bookmark, time-machine ) Function can be done automatically.

In addition, as shown in FIG. 11C or 11D, when the call application data is provided through a window on a part of the screen instead of the front of the screen of the digital TV, previously provided mirroring data or TV service data may be stopped. It can be provided continuously, but the audio can be muted. In this case, the muted audio data may be subjected to caption processing or subtitle processing corresponding thereto. However, if playback is stopped, the bookmark and time machine functions may be automatically performed.

Providing the call application screen on the mobile terminal of FIGS. 11B to 11D in the digital TV may be performed not only at the time of initial call connection but also in the middle of using the call application through the mobile terminal.

12 is a diagram illustrating a method of processing mirroring data and call application data according to an embodiment of the present invention.

Mirroring data is transferred from the mobile terminal 720 to the digital TV 710 in the same manner according to the Wi-Fi Direct communication protocol, as shown in FIG. 9 described above. At this time, if the Bluetooth connection is activated between the mobile terminal 720 and the digital TV 710 for a call connection while processing the mirroring data, the voice data of the caller is transmitted through the Bluetooth communication protocol. In addition, if the video call application is executed in the mobile terminal when the call is connected according to the incoming call, the previously transmitted mirroring TS is interrupted and the image / video data for the video call is transmitted in the TS form according to the Wi-Fi Direct communication protocol. . The video call TS is demultiplexed by the demultiplexer 1220 through the receiver 1210 of the digital TV. The demultiplexed image / video data is transmitted to the video decoder 1230, but the demultiplexed audio data is audio. Discard it without passing it to the decoder 1240. In other words, audio data in the video call TS is not decoded by the audio decoder 1240. On the other hand, the caller's voice data received from the mobile terminal 720 according to the Bluetooth communication protocol is passed through the receiving unit 1210 or the receiving unit 1210 and the demultiplexing unit 1220 of the digital TV 710 to the audio decoder 1240. It is passed to and decoded. The video data and audio data decoded by the video decoder 1230 and the audio decoder 1240 are output through the screen and the speaker of the digital TV 710, respectively.

In the above, the caller's image / video data and audio data may have different paths or communication protocols from the mobile terminal 720 to the digital TV 710, and the data formats thereof may be different. In addition, each transmitted data may also have different processing processes or paths within the digital TV 710. In addition, problems such as noise and lip sync may occur in the process of processing the call application data on the digital TV 710. This will be described in more detail with reference to the accompanying drawings.

FIG. 13 is a flowchart for describing a method of processing call application data of a mobile terminal using a digital TV and a remote controller according to an exemplary embodiment.

Here, FIG. 13 may be viewed as a detailed flowchart of FIG. 7. The digital TV 1320 or the remote controller 1310 may be replaced with a wearable device (eg, a smart watch). In addition, the mobile terminal 1330 may also be replaced with a wearable device.

Referring to FIG. 13, in order to provide a call service in the digital TV 1320 according to the present invention, the remote controller 1310 and the mobile terminal 1330 are paired with each other (S1302 / S1304). Its order does not matter. On the other hand, the remote control 1310 may not be performed a separate pairing process as a dedicated control means mainly set with the digital TV 1320.

In FIG. 13, the above-described process of transmitting and receiving mirroring data is omitted for convenience.

When the incoming call is detected after the pairing (S1306), the mobile terminal 1330 transmits the incoming guide data according to the incoming detection to the digital TV 1320 (S1308), and the digital TV outputs the incoming guide data on the screen. (S1310).

When the digital TV 1320 receives the first control command regarding the output destination guide data through the remote controller 1310 (S1312), the digital TV 1320 transmits it to the mobile terminal 1330 to request first call application data (S1314). ).

At this time, the digital TV 1320 and the mobile terminal 1330 are connected to each other via Bluetooth for call service (S1316). When the Bluetooth connection is activated, the mobile terminal 1330 transmits the requested first call application data to the digital TV 1320 (S1318). As described above, the caller's image / video data in the first call application data is delivered in a Wi-Fi direct manner, and the caller's voice data is delivered in a Bluetooth manner.

The digital TV 1320 processes the received first application data and outputs the same through the screen and the speaker (S1320).

The remote control 1310 transmits second call application data about the called party's video / audio data to the digital TV 1320, and the digital TV 1320 moves the second call application data received from the remote control 1310. Transfer to terminal 1330. The called party's video / voice data is transmitted to the caller through the mobile terminal in the same manner as the above-mentioned caller's video / voice data (S1324).

The remote controller 1310 transmits a second control command for terminating the call service to the digital TV 1320 (S1326), and the digital TV 1320 transmits the second control command to the mobile terminal 1330 (S1328). ). The mobile terminal 1330 transmits a response according to the reception of the second control command to the digital TV 1320. That is, the call service ends.

Meanwhile, steps S1318 to S1324 may be repeatedly performed at the end of the call service, that is, until the second control command is received by the mobile terminal 1330.

FIG. 14 is a view illustrating a lip sync problem solving method generated in a call application data processing process through a digital TV according to an embodiment of the present invention, and FIG. 15 is a diagram illustrating a digital TV according to an embodiment of the present invention. Here is a flow chart of the lip sync processing method.

As described above, the call application data of the mobile terminal, i.e., the caller's image / video data and the caller's voice data, are provided to the digital TV according to different communication protocols and paths. At this time, the key is how the digital TV fits the lip sync of the caller's image / video data and the caller's voice data to provide a call service. If the lip sync is not matched, the called party may feel uncomfortable with the call service. Therefore, the digital TV must solve the lip sync problem.

In the present specification, the following embodiments are disclosed to solve a lip sync problem according to a call service in a digital TV.

According to an embodiment of the present invention, the lip sync is corrected using a time-stamp. At this time, the issuer of the time stamp is a mobile terminal. In other words, the mobile terminal generates and transmits a timestamp when transmitting call application data to the digital TV. Here, the time stamp may be included in both the caller's image / video data and the caller's voice data, or may be included only in the caller's voice data. The timestamp may be included in a header structure of the corresponding data and transmitted.

For example, the caller may not always speak while using the call service. Therefore, when transmitting the caller's voice data, processing of the caller's voice data in the actual voice absence section may be problematic. In this case, the mobile terminal may not transmit the voice data of the caller's actual voice absent section or insert null data. On the other hand, the time stamp may be included only in all or part of the data frame (data frame) transmitted every time. In the latter, in particular, the timestamp may be included only in voice data in which the caller's actual voice is present.

According to another embodiment of the present invention, a lip sync is corrected by instantly reproducing call application data, that is, image / video data and audio data received from a mobile terminal in a digital TV (No delay). Digital devices typically output decoded video data and audio data after being temporarily stored in a buffer. This may be more difficult to sync, without one of the methods for syncing or the time stamps described above. Therefore, in order to correct this, the present invention outputs decoded video data and audio data without delay immediately after decoding. In this way, the output in the no delay system can solve the lip sync problem.

In addition, according to the present invention, the time stamp and the no delay scheme may be combined and used for lip synch correction. For example, the lip sync is corrected using a timestamp for the original image / video frame and the voice frame of the sender, and a no delay method is applied to subsequent frames.

The digital TV may be processed as shown in FIG. 15 for lip synch correction. Referring to FIG. 15, when the call application data is received (S1502), the digital TV decodes it (S1504). Here, the call application data is collectively referred to without distinguishing between audio and video data. For the specific processing, refer to the above description.

The digital TV determines whether or not the time stamp is included in the call application data from the decoded call application data (S1506).

As a result of the determination in step S1506, if the time stamp is included in the call application data, the data is processed according to the time stamp and the caller's image / video data is synchronized with the caller's voice data and output through the screen and the speaker, respectively ( S1512). In this case, as described above, the time stamp scheme may be used together with the no delay scheme (S1510).

As a result of the determination in step S1506, if the time stamp is not included in the call application data, the digital TV processes the caller's image / video data and the caller's voice data to be output directly without delay (S1510) through the screen and the speaker. Output each (S1512).

FIG. 16 is a diagram illustrating an audio engine for improving call service quality when providing a call service through a digital TV according to one embodiment of the present invention.

Referring to FIG. 16, a called party may transmit voice data to a mobile terminal using a microphone of a remote controller. In this case, the voice data may include not only the voice data of the called party but also the content or caller voice data being output through the speaker of the digital TV.

In other words, when a video / audio call is made through a digital TV instead of a call through the mobile terminal itself, that is, the mobile terminal according to the present invention, the call quality depends on the attributes or characteristics of the mobile terminal and the digital TV. This may be different. For example, there may be an echo leak due to a difference in the output of the speaker of the mobile terminal and the speaker of the digital TV. And while the mobile terminal is short or almost in contact with the distance between the speaker and the called party, the distance between the speaker and the called party may be relatively longer than that of the mobile terminal. This may require control of the output level. On the other hand, when the speaker and the microphone of the mobile terminal are significantly less or less likely to include noise between the called party and the caller's call, when using the microphone of the remote control connected to the digital TV, the speaker of the digital TV is relatively The noise of the caller's voice data output through the audio, and audio data of a service such as other broadcasts may be included. In addition, there may be a problem of deterioration of audio quality due to increased audio delay. Therefore, in order to improve call quality in the process of processing call application data of a mobile terminal through digital TV, in particular, separate processing of audio data may be required.

In the present invention, as shown in FIG. 16, an audio engine is configured in a digital TV, a remote control for the digital TV, and other control devices to improve call quality. In the audio engine, a noise reduction (NR) for removing a fan sound, an auto gain control for adjusting an output level according to a distance between a speaker and a called party or an output difference between a mobile terminal and a digital TV speaker; AGC), at least one or more of acoustic echo cancellation (AEC) for removing noise generated when the called party's own voice is included. In addition, the digital TV corrects the service data or the caller's voice, such as a broadcast being output through the speaker, among the voice data of the called party input through the microphone of the remote controller. Meanwhile, in the present invention, such an audio engine may be processed by hardware or software.

On the other hand, the digital TV can process not only the voice data of the called party to be transmitted to the mobile terminal by using the remote control but also the voice data of the caller received from the mobile terminal to process call quality improvement such as output level adjustment. .

17 is a diagram illustrating an embodiment of guide data for a noise sound reduction method when processing call application data through a digital TV according to the present invention.

FIG. 17 is a screen for providing guide data for controlling call quality improvement processing using an audio engine as shown in FIG. 16 while using a setup menu or a call application in a digital TV.

Referring to FIG. 17, the digital TV provides the user with guide data on whether to use an audio engine or a volume reduction method to reduce or remove noise sound, and operate according to a user's selection. .

For example, when an audio engine is used, there may be a problem such as a power consumption of a chip-set such as a CPU. Therefore, it is a guide to using a method of minimizing noise by simply reducing the volume. For example, such guide data may be useful or efficient in the case of a device sensitive to power consumption or battery level.

Meanwhile, in the present invention, the digital device may automatically perform audio processing by applying either of the above methods, without considering the guide as shown in FIG.

The above description has mainly been made in the case of a video call between the mobile terminal and the digital TV during data sharing (mirror service) such as Miracast. If only the voice call is desired instead of the video call, the above description is applicable except for the image / video processing. On the other hand, when only a voice call is made, the digital TV can continuously watch the mirroring data or the TV data without interruption, but mutes only the audio data among the mirroring data or the TV data. In this case, if there is caption or sub-title data, subtitle data corresponding to the voice data automatically muted through the same may be provided.

On the other hand, even when the digital TV and the mobile terminal are not paired and / or Miracast is activated, even if a call connection request is made to the mobile terminal while the digital TV is being watched, that is, a call service is received through the digital TV. Enjoy.

In the above, when the video call is received, the mobile terminal may be provided with a menu for selecting a device to use the video call service on the screen of the mobile terminal. Briefly, a menu item may be provided to select a mobile terminal, a digital TV, a wearable device, a tablet PC, a notebook, and the like. The provision of such menus and menu items may be operated, for example, in a setting or a specific mode, and may be provided when there is an external device of a pairable or paired mobile terminal.

In this case, first, image / video data obtained from a camera sensor of the mobile terminal 1820 that is automatically turned on according to an incoming call is outputted. Unlike FIG. 18, if the mobile terminal is not near a user or the camera sensor is output. In some cases, it may be difficult to acquire the image / video of the right called party because of the wrong direction. In this case, when accessing the second window on the user digital TV 1810, a guide on whether the mobile sensor 1820 activates or deactivates the camera sensor, whether the digital TV 1810 uses the camera sensor, and whether the peripheral camera sensor is used. You can provide data and follow your choices. Meanwhile, when a peripheral camera sensor is detected, a list thereof may also be provided. In the case of using a peripheral camera sensor, the image / video data of the called party is transmitted via the digital TV 1810 or directly to the mobile terminal 1820, and then again via Wi-Fi Direct through the mobile terminal 1820. ) May be provided on the screen of the digital TV 1810. In addition, when it is desired to change the image / video data of the called party provided in this way, it is possible to access and change the above-mentioned second window.

On the other hand, as described above, it can be applied to the video call origination as well as video call incoming.
