The switch 460 may allow only one output of the outputs of the first data processor 430 and the second data processor 450 to pass therethrough. For example, when executing an image communication or application, the switch 460 is connected to the first data processing unit 430 so that only the output of the first data processing unit 430 can be passed. On the other hand, when watching a broadcast, the switch 460 is connected to the second data processing unit 450 so that only the output of the second data processing unit 450 can pass.

The display unit 470 displays data output through the switch 460. Preferably, the display unit 470 may include a display driver.

In addition, the data transceiver 600 may receive data from an external device. The data transceiver 600 preferably uses a modem, but is not limited thereto. The second interface 660 receives the image frame input from the data transceiver 600 and transmits the image frame to the first data processor 620. The second interface 660 is suitable for transmitting a small amount of data. The second interface 660 is suitable to use an external bus interface (EBI), but is not limited thereto. The second interface 660 has a smaller processing capacity of data and a lower speed than the first interface 670.

In addition, the first interface 670 receives broadcast data from the second data processor 640 and transmits the broadcast data to the first data processor 620. The first interface 670 is suitable to use a camera interface, but is not limited thereto. The first interface 670 is the same as the second interface 490 in FIG. 4. While the second interface 490 in FIG. 4 is connected between the first data processor 430 and the first camera 410, the first interface 670 in FIG. 6 may include the first data processor 620 and the first data processor 620. There is a difference between the two data processing units 640.

The second interface 660 and the first interface 670 are data lines capable of transmitting data, and the first DSP 620 and the second DSP 640 transmit the input data to various data transmission schemes. A configuration for converting into a suitable form or converting into a suitable form that can be recognized by a component receiving the input data may be included therein.

As described above, according to the present invention, the image frame processed by the first camera 610 is transmitted to the data transceiver 600 through the first interface 670, the data transceiver 600 is received By transmitting the image frame to the external device, the image frame data can be transmitted to the external device at a higher speed since the second frame 660 which has a small processing capacity and does not need to go through the slow speed can be transmitted.

The first data processor 620 receives the image frame input from the second interface 660, converts the image frame into a form suitable for display on the display unit 650, and outputs the converted image frame.

An image frame is displayed through the first camera 610, the first interface 670, the data transceiver 600, the second interface 660, and the first data processor 620. The process displayed on 650 includes a case of making a video call. The displayed process refers to a process of allowing a user of the mobile terminal to see his / her appearance through the display unit 650. Since the window displayed on the display unit 650 is small in size, the capacity of the displayed image frame is small. Therefore, the image frame may be smoothly processed even when transmitted to the first data processor 620 using the second interface 660.

As described above, even when the camera is connected to the data transmission / reception unit through the interface instead of the control unit through the interface, the image quality or performance of the display window in which the user of the mobile terminal can see his / her appearance while making a video call is maintained. That is, according to the present invention, it is possible not only to transmit the image frame processed by the camera to an external device at a high speed, but also maintain the image quality or performance of the display window which can see itself during a video call.

The tuner 630 may receive broadcast data transmitted from the outside.

The second data processor 640 converts the broadcast data received through the tuner 630 into a form suitable for being displayed on the display unit 650. The form suitable to be displayed on the display unit 650 may be an RGB format. However, it is not limited to the RGB format. When only broadcast viewing is being performed, the second data processor 640 transmits the converted broadcast data to the display unit 650. On the other hand, when the broadcast data and the application are being executed at the same time, the second data processor 640 transmits the converted broadcast data to the first interface 670. The first data processor 620 and the second data processor 640 may include an output limiter for limiting output therein. The output limiter may limit the output of any one of the first data processor 620 and the second data processor 640 to be output. Details of the output limiting unit and the limiting process will be described later.

The display unit 650 displays the data output from the first data processor 620 or the second data processor 640.

Suitable broadcast standards of the present invention are DVB-T or DVB-H. However, it is not limited to the broadcast standard.

Referring to FIG. 6, a process 680 of executing broadcast viewing only using a mobile terminal and a process 690 of simultaneously executing broadcast viewing and an application are shown.

In step 680, the tuner 630 receives broadcast data, and the second data processor 640 converts the broadcast data input from the tuner 630 into a form suitable for display on the display unit 650. The method may include transmitting the converted broadcast data to the display unit 470 and displaying the converted broadcast data by the display unit 650. In this process, the output limiter of the first data processor 620 limits the output of the first data processor 620. On the other hand, the output limiter of the second data processor 640 does not limit the output of the second data processor 640.

As described above, by limiting the output of the first data processor 620 and the second data processor 640, the first data processor 620 and the second data processor 640 are displayed at a rear end of the display unit 650. ) Is always connected to reduce power consumption. In mobile terminals, reducing power consumption is an important factor.

The process 690 shows a process of executing an application while watching a broadcast. In step 690, the tuner 630 receives the broadcast data, and the second data processor 640 converts the broadcast data input from the tuner 630 into a form suitable for display on the display unit 650. Transmitting the converted broadcast data to the first data processor 620 through the first interface 670, and the application 160 requested by the first data processor 620 through the user input unit 130 to memory 160. Reading), converting the read application into a form suitable for display on the display unit 650, and then transmitting the converted broadcast data and the converted application to the display unit 650. The display unit 650 is configured to display the converted broadcast data and the converted application. The various applications and the broadcast data are displayed in an overlapping form on the display unit 650.

In this process, the output limiting unit of the first data processing unit 620 does not limit the output of the first data processing unit 620. On the other hand, the output limiter of the second data processor 640 limits the output of the second data processor 640. In addition, since the first interface 670 has a larger capacity of data that can be processed than the second interface 660 and a faster processing speed, the first interface 670 smoothly converts the broadcast data converted by the second data processor 640 into the first data. The processor 620 may transmit the data. The first interface 670 is suitable to use a camera interface (CAMIF) that has a large capacity of data that can be processed and a fast processing speed, but is not limited thereto. As described above, when simultaneously executing a broadcast viewing and an application, the broadcast data processed by the second data processor 640 is not transmitted through the second interface 660 having a small processing capacity, and the first interface 670. As transmitted, the picture quality or performance of the broadcast may be maintained as in the case of watching only the broadcast.

As described above, as described above, the difference between the configuration of FIG. 4 and the configuration of FIG. 6 is that the position of the second interface and the position of the first camera are changed.

According to the present invention, even when simultaneously executing a broadcast viewing and an application, the application can be executed while maintaining the quality or performance of the broadcast as it is.

In addition, by implementing only by changing the position of the existing interface, rather than adding a new interface, it is more useful in the mobile terminal with a large size limit and a capacity limitation that can process data.

7 is a view of yet another embodiment of a switch according to the present invention.

For example, when only a video call is executed or only a specific application is executed, the first data processor 620 converts and outputs data for executing an image frame or an application required for the video call. In this case, the controller 180 controls the first output limiter 732 not to limit the output of the first data processor 620. On the other hand, the controller 180 controls the second output limiter 734 to limit the output of the second data processor 640.

If only broadcast viewing is performed, the second data processor 640 converts and outputs the broadcast data. In this case, the controller 180 controls the second output limiter 734 not to limit the output of the second data processor 641. On the other hand, the controller 180 controls the first output limiter 622 to limit the output of the first data processor 620.

In the case of simultaneously executing a video call or an application and watching a broadcast, the second data processor 640 converts the broadcast data into a form suitable for display, and converts the broadcast data through the first interface 670. 1 is transmitted to the data processing unit 620. The first data processor 620 converts an image frame or an application into a form suitable for display, and outputs the broadcast data and the converted image frame or application received from the first interface 670. In this case, the controller 180 controls the first output limiter 732 not to limit the output of the first data processor 620. On the other hand, the controller 180 controls the second output limiter 734 to limit the output of the second data processor 640.

The location of the first output limiter 732 and the second output limiter 734 may be configured as a single chip inside the first data processor 620 and the second data processor 640. It may be composed of a chip configured separately.

As described above, the first output limiting unit 732 and the second output limiting unit 734 limit the output of any one of the first data processing unit 620 and the second data processing unit 640. By doing so, there is an advantage in that it is always possible to reduce the power consumption of being connected to the display unit 650 at the rear end.

In addition, since an output limiting unit exists in the first data processing unit 620 and the second data processing unit 640, a separate switch 730 may be removed, thereby securing space.
