Fig. 1 is a diagram showing the structure of a mobile terminal 100 having a digital broadcast receiver for changing a service channel according to an embodiment of the present invention and an external device 200 displaying broadcast data transmitted from the mobile terminal 100.

Referring to FIG. 1, the controller 110 controls the overall operation of the portable terminal equipped with the digital broadcast receiver. The key input unit 140 generates key data according to the user's selection and applies it to the control unit 110. Here, the user's command generated through the key input unit 140 may generate key data for controlling the operation of digital broadcasting and the mobile terminal. The control unit 110 uses a codec (coder & decoder) to encode and transmit the encoded data, and a modulator (MODEM) to demodulate and demodulate the encoded transmission data. The data processing unit can be configured. The data processing unit may be separated from the control unit 110 and configured between the communication unit 120 and the control unit 110. In addition, the controller 110 demodulates and transmits broadcast data of the selected broadcast channel when the external device 200 requests digital broadcast playback, and controls a function of setting or switching a broadcast channel under the control of the external device.

The memory 130 may consist of a program memory for controlling the operation of the digital broadcast receiver and a program memory for storing a program for communicating broadcast information with an external device 200 and a data memory for storing data generated during program execution.

The communication unit 120 performs outgoing and incoming communication functions of the mobile terminal. Here, the communication unit 120 may be equipped with a frequency converter for increasing and converting the frequency of transmission data, and for decreasing the frequency of the reception data and a duplexer for separating data transmitted and received through an antenna. In addition, the data processing unit of the control unit 110 may be included.

The digital broadcast receiver 170 selects, receives, and demodulates, decodes, and outputs the broadcast data received by the control unit 110. The digital broadcast receiver 170 can be equipped with a tuner, a demodulator and a decoder. The digital broadcasting receiver 170 may be a digital multimedia broadcasting receiver or a digital video broadcasting receiver. The DMB receiver can be a terrestrial or satellite DMB receiver, and the DVB receiver can be a DVB-T or DVB-H receiver.

The digital broadcast receiver 170 selects, demodulates, decodes, and outputs the broadcast data received under the control of the controller 110. The digital broadcast receiver 170 can be equipped with a tuner, a demodulator and a decoder. The digital broadcasting receiver 170 may be a digital multimedia receiver (Broadcasting receiver) or a digital television receiver (DVB receiver).

The speaker 160 and the display unit 150 perform a function of reproducing the broadcast data output from the digital broadcast receiver 170 and the data of the mobile terminal output from the controller 110.

The short range communication unit 180 performs a close range communication function with the external device 200 under the control of the control unit 110. In the embodiment of the present invention, the near-field communication unit 180 converts and demodulates the demodulated broadcast data generated by the digital broadcast receiver 170 to the corresponding near-field communication method under the control of the control unit 100, and transmits the data generated by the control unit 110. do. In addition, the mobile station receives the data transmitted from the external device 200 and transmits the data to the control unit 100. Here, the near field communication unit 180 may use Bluetooth communication, WiBro, WiMAX, wireless LAN, and USB communication methods. In the embodiment of the present invention, the near field communication unit 180 is assumed to be a Bluetooth communication unit. In the case of using the Bluetooth communication method, the mobile terminal 100 and the external device 200 must each have a Bluetooth communication unit, and each of them must be paired in a state capable of communicating with each other. In addition, you must set up a communication link that can communicate broadcast data and control information in the short-range communication mode. Here, the method of setting the pairing and communication link can be performed by the normal Bluetooth communication protocol.

FIG. 2 is a diagram showing the configuration of the mobile terminal in FIG. 1 above, and shows the configuration of the digital broadcast receiver 170. As shown in FIG.

Referring to FIG. 2, the digital broadcast receiver 170 tunes the frequency of the channel selected by the user under the control of the control unit 110 to tune the tuner 171 to receive broadcast data, and the demodulator 173 to demodulate the broadcast data of the selected channel frequency. It consists of a decoder 175 which extracts audio, video and broadcast data from the demodulated broadcast data and outputs it through the corresponding decoder.

The output of the demodulator 173 is transmitted to the short-range communication unit 180 and transmits the output of the demodulator 173 to the external device 180 under the control of the control unit 110.

First, the controller 110 sets a frequency for receiving data of a user's selected broadcast channel in the tuner 171 during digital broadcast playback. The tuner 171 then tunes to the set frequency channel and receives the set broadcast channel data. The demodulation unit 173 demodulates the data of the broadcast channel into original data and outputs the demodulated data. The decoder 175 classifies audio, video, and broadcast information from the demodulated broadcast data, and then decodes them through corresponding decoders. The decoded audio data is reproduced through the speaker 160 and the video data is reproduced through the display unit 150.

In the embodiment of the present invention, the controller 110 transmits the data to the external device 200 of the digital broadcast receiver 170 and controls the external device 200 to control the operation of the digital broadcast receiver 170. That is, when the external device 200 requests for playback of a digital broadcast, the control unit 110 receives the data through the short-range communication unit 180, checks the selected broadcast channel in the external device 200, and checks the identification information of the corresponding broadcast channel. It transmits via the communication unit 180, and controls the tuner 171 to set the frequency channel so that the data of the selected broadcast channel can be received. The control unit 180 controls the short-range communication unit 180 to transmit the demodulated broadcast data output from the demodulator 173 to the external device 200. In this case, the controller 110 may transmit demodulated data output from the demodulator 173 to the decoder 175, and may not be transmitted. In other words, when the digital broadcast data is played back through the external device 200, the decoder 175 of the mobile terminal can be selectively controlled so that it may or may not be operated.

The digital broadcast receiver 170 may be configured in different forms depending on the broadcast method. The digital broadcast receiver has a DVB method and a DVB method. The DVB method includes a terrestrial DMB and a satellite DMB method, and the DVB method includes DVB_T and DVB_H methods. The broadcast data of the "DMB" and "DVB" methods have a MPEG2-TS structure, and the broadcast data of the MPEG2-TS structure is a packet stream, and each packet is composed of a packet header and a payload. In addition, the packet header contains PID information, which is an identifier for identifying a broadcast channel. Therefore, the digital broadcast receiver 170 can select the selected broadcast channel using the PID information. At this time, the payload of each packet having the MPEG2_TS structure in the DMB and DVB_T digital broadcast receivers is filled with broadcast data (audio, video, and broadcast data), and the MPEG2-TS structure in each digital broadcast receiver of the DVB_H method is used. The payload of the packets is filled with IP information and broadcast data. Therefore, the demodulator 173 demodulates the service channel data and generates the MPEG-2 TS. Therefore, the demodulated TS data output from the demodulator 173 is transmitted to the near field communication unit 180 and / or the decoder 175. At this time, the "TS data" is "compressed" coded "data", and thus "broadcast data" transmitted through the short-range communication unit 180 is compressed coded broadcast data. Therefore, since the compressed broadcast data is transmitted to the external device 200 through the near field communication unit 180, the transmission rate of the broadcast data can be improved because the transmission rate of the decoded broadcast data is very good.

In the embodiment of the present invention, the controller 110 transmits the digital broadcast data to the external device 200 of the digital broadcast receiver 170, and controls the operation of the digital broadcast receiver 170 under the control of the external device 200. That is, when the external device 200 requests for playback of digital broadcasting, the control unit 110 receives the data through the short-range communication unit 180, checks the selected broadcast channel in the external device 200, and checks the identification information of the corresponding broadcast channel. It transmits via the communication unit 180, and controls the tuner 171 to set the frequency channel so that the data of the selected broadcast channel can be received. The control unit 180 controls the short-range communication unit 180 to transmit the demodulated broadcast data output from the demodulator 173 to the external device 200. At this time, the control unit 110 may transmit the demodulated data output from the demodulator 173 to the decoder 175, and may not be transmitted. That is, when the digital broadcast data is played back through the external device 200, the decoder 175 of the mobile terminal can be selectively controlled so that it may or may not be operated.

The control unit 110 of the mobile terminal can receive an operation control command of the digital broadcast receiver 170 through the key input unit 140, and can also receive an operation control command transmitted from the external device 200 via the local area communication unit 180. When reproducing the output of the digital broadcast receiver 170 to the external device 200, the controller 110 transmits an identifier (PID, etc.) of the selected broadcast channel to the external device 200 through the local area communication unit 180. The external device 200 can then demultiplex the video and audio data of the selected broadcast channel from the demodulated data received by the identifier information of the selected broadcast channel, and also extract the broadcast information, the video, audio and broadcast information. The information can be decoded and played back through the corresponding decoder.

In addition, the control unit 110, when the incoming or outgoing communication function is set in the state of playing the digital broadcast data through the external device 200, the output of the digital broadcast receiver 170 is transmitted to the external device 200 at the same time the outgoing or incoming communication function. You can service it.

The controller 110 blocks transmission of the data set by the user from the received data to the external device. That is, the user blocks transmission of the personal information of the user from the received data to the external device. The user's personal information may include a name at the time of receiving a call, a phone number or a name or a phone number of a message sender at the time of receiving a message, and contents of a message. Phonebook, schedule, memo and alarm related information stored in the mobile terminal are also included in the user's personal information.

That is, when the call is received, the control unit 110 only transmits the information that the call was received instead of transmitting the caller's name or telephone number to the external device. The controller 110 transmits only supplementary information that there is a schedule, instead of transmitting detailed information related to the schedule, to the external device.

3 is a diagram showing the configuration of an external device 200 for playing back digital broadcast data transmitted from the mobile terminal 100 according to an embodiment of the present invention. The external device 200 may be a personal computer, a TV, or the like.

That is, when the call is received, the control unit 110 only transmits the information that the call was received instead of transmitting the caller's name or telephone number to the external device. The controller 110 transmits only auxiliary data indicating that there is a schedule, instead of transmitting detailed information related to the schedule, to the external device.

In addition, when the digital broadcast playback mode is set, the near field communication unit 220 receives the demodulated broadcast channel data, and the decoder 230 classifies the demodulated broadcast data into audio, video and broadcast information, and sends them through corresponding decoders. The decoded audio data is decoded and reproduced through the speaker 250, and the decoded video data is reproduced through the display unit 240. In addition, the decoded broadcast information is stored in the memory 270, and, if necessary, reproduced through the display unit 240 and the speaker 250 under the control of the control unit 210.

As described above, the mobile terminal 100 controls the operation of the digital broadcast receiver 170 to reproduce the received broadcast data. When the digital broadcast data is reproduced through the external device 200, the mobile terminal 100 outputs the demodulated broadcast data of the digital broadcast receiver 170 via the short-range communication unit 180. Then, the external device 200 also receives the demodulated broadcast data through the internal short-range communication unit 220, and decodes the received broadcast data through the internal decoder 230 and plays it back. At this time, the external device 200 may generate a control command for controlling the operation of the digital broadcast receiver 170 to the mobile terminal 100, and the mobile terminal 100 receiving the control command controls the operation of the digital broadcast receiver 170 accordingly. do.

In the state where the digital broadcast data is reproduced through the external device 200, the mobile terminal 100 can perform incoming and outgoing communication functions. This is the state where the mobile terminal 100 only sets the path of the digital broadcast data, and thus the mobile terminal 100 can set the communication path to perform the incoming call and communication functions independently of the digital broadcast receiver 170 through the communication unit 120. Because. In this case, the user of the mobile terminal 100 can perform the communication function by using the mobile terminal 100 while watching the digital broadcast being played on the external device 200. At this time, the voice call function and data communication path of the mobile terminal 100 can be formed independently of the digital broadcast.

In addition, the controller 210 may perform the same operation as that performed by the controller 110 of the portable terminal. That is, the controller 210 blocks output of the data set by the user from the received data to the display unit 240.

4 is a flowchart illustrating an operation performed by the controller 110 of the portable terminal according to an embodiment of the present invention. Hereinafter, an operation performed by the controller 110 of the portable terminal according to an embodiment of the present invention will be described in detail with reference to FIG. 4.

In step S400, the control unit 110 sets a personal information blocking mode according to the operation data of the key input unit 140. As described above, the personal information includes a name at the time of receiving a call, a telephone number or a name or a telephone number of a message sender at the time of receiving a message, and the content of the message. Phonebook, schedule, memo and alarm related information stored in the mobile terminal are also included in the personal information.

In step S402, the controller 110 determines whether data to be transmitted to the external device is generated. If the data transmitted to the external device as a result of the determination occurs, go to step S404, and if the data to be transmitted to the external device is not generated as a result of the determination, move to step S402. Data to be delivered to the external device may vary depending on the user's settings. That is, the user may be configured to transmit only specific data to the external device or to transmit all generated data to the external device. In general, it is preferable that the user sets to transmit all generated data to the external device.

In step S404, the controller 110 determines whether user personal information is included in the generated data. That is, when a call is received, the controller 110 determines whether caller information or a caller's phone number is included in relation to the received call. Alternatively, if the generated data is schedule data, the controller 110 determines whether personal information is included in the schedule data. The personal information related to the schedule data may include detailed information of the schedule (time information related to the schedule, person information, place information, etc.). If the personal information is included in the data generated as a result of the determination, the control unit 110 moves to step S406, and if the personal information is not included, moves to step S408.

In step S406, the controller 110 generates auxiliary data corresponding to the generated data. If the generated data is call reception data, the auxiliary data is " Call has arrived. &Quot; If the generated data is constant data, the auxiliary data can be " scheduled. &Quot; The auxiliary data may be preset for each data that can be generated according to the user's setting.

In step S408, the controller 110 transmits the generated data to an external device. That is, if the generated data is broadcast data, the controller transmits the generated data to an external device. In step S410, the controller transmits auxiliary data corresponding to the generated data to an external device. In other words, if the generated data is call reception data, the control unit transmits ancillary data "Call came" to the external device.

Hereinafter, an operation performed by the controller 210 of the external device according to an embodiment of the present invention will be described in detail with reference to FIG. 5. 5 illustrates a process of blocking personal information by the controller 210 of the external device. That is, the controller 210 of the external device controls the display unit 240 to display the data transmitted from the mobile terminal according to a user's setting, or displays the remaining data except for user personal information among the data received from the mobile terminal. You can control it to display.

In step S500, the control unit 210 sets the personal information blocking mode according to the operation data of the key input unit or the control data received from the portable terminal device.

In step S502, the controller 210 determines whether data is received from the mobile terminal. Data received from the mobile terminal includes broadcast data, call data, schedule data, and the like. As a result of the determination, the control unit 210 moves to step S504 when data is received from the mobile terminal, and if no data is received from the mobile terminal as a result of the determination, moves to step S502.

In step S504, the controller 210 determines whether the received personal information is included in the received data. The personal information is the same as described above. If the received data includes personal information, the controller 210 moves to step S506. If the received data does not include personal information, the controller 210 moves to step S508.

In step S506, the controller 210 generates auxiliary data corresponding to the generated data. If the generated data is call reception data, the auxiliary data is " Call has arrived. &Quot; If the generated data is constant data, the auxiliary data can be " scheduled. &Quot; The auxiliary data may be preset for each data that can be generated according to the user's setting.

In operation S508, the controller 210 controls the generated data to be displayed on the display unit 240. That is, if the generated data is broadcast data, the controller 210 controls the generated data to be displayed on the display unit 240. In step S510, the controller 210 controls the display unit 240 to display auxiliary data corresponding to the generated data. That is, if the generated data is call reception data, the controller controls the display unit 240 to display auxiliary data "Call came."

As described above, the user may set the personal information blocking mode to either the mobile terminal or the external device, or both.
