In the display device 100 of FIG. 23, a communication module 190 capable of communicating with a server by wire or wireless is mounted. The communication module 190 may include an Ethernet module, a Wifi module, a Bluetooth module, an IPTV set-top box, an RF communication module, and any communication module capable of transmitting and receiving data with the server. The communication module 190 can receive a file containing data to replace the existing boot screen data or boot sound data from the server.

The server operator creates new boot output data and puts the new boot output data into a state in which it can transmit and receive to the display device 100. [ The new boot output data may be in the same format as the file already stored in the display apparatus 100.

The new boot output data file can have a specific file name. When the display device 100 is turned on and connected to the server through the communication module 190, the processor 140 determines whether the data received through the communication module 190 includes boot output data. Whether or not the boot output data file is included can be indicated by assigning a specific field to the header of the received data, or from a specific file name.

The processor 140 loads the received boot output data into the second memory 160 and stores the boot output data in the boot output data area of the information stored in the first memory 130, Overwrite the data or boot sound data. As a result, the changed boot output data is output from the next boot.

In step S902, it is determined whether or not there is new boot output data in the data received from the server using the file name or the field value. If there is no new boot output data, the process is terminated.

If there is new boot output data to be updated, the boot output data previously stored in the display device 100 is overwritten with new data in step S903.

25 shows a configuration diagram of a display device in which a display device can change boot output data in a standby state, according to another embodiment of the present invention.

25 shows a configuration in which the display apparatus 100 is a digital TV and includes a display unit 110, a speaker 120, a first memory 130, a processor 140, a tuner 150, 160 are the same as those shown in Fig.

A communication module 190, a sub-processor 191, and a sub-memory 192 are mounted on the display device 100 of Fig.

The sub-processor 191 is a processor that operates even when the display apparatus 100 is in the standby mode. In the standby mode, the sub-processor 191 can perform an operation of performing communication with the communication module 190 and controlling an IR receiver (not shown) to receive an input of the remote controller.

The sub memory 192 is a memory for temporarily storing the boot output data received by the communication module 190 when the display apparatus 100 is in the standby mode. The new boot output data stored in the sub memory 192 replaces the existing boot output data stored in the first memory 130 by the sub processor 191. [

With this configuration, even when the display apparatus 100 is in the standby mode, the boot output data can be changed and the information necessary for the user can be efficiently provided. For example, when the display device 100 is a digital TV disposed in a hotel room, in the standby mode, the guest information of the boot screen data is received through communication between the hotel server and the communication module 190, You can update to the name of the guest. Accordingly, when the guest enters the room for the first time and turns on the digital TV, the boot screen containing his / her name can be seen as shown in FIG.

In some embodiments, the display device 100 may be turned on by the communication module 190 at the server (e.g., a hotel server) while the display device 100 is in the standby mode, and then the boot output data may be changed. In this case, the process of changing the boot output data after turning on can be applied to the method described with reference to FIG. 23 and FIG.

26 is a flowchart showing a method of changing boot output data in the display device shown in Fig.

In step S1001, the display device 100 receives data from the server through the communication module 190 under the control of the sub processor 191 while the display device 100 is in the standby mode.

In step S1002, it is determined whether the received data includes new boot output data. The presence or absence of new suboutput data can be confirmed from the information of the file name or the header portion of the received data. If there is no new boot output data in the received data, the process goes back to the standby state, and if there is new boot output data, the process proceeds to the next step.

The communication between the communication module 190 and the server during the standby mode may be performed in real time, but may be configured to perform communication at a predetermined time interval, for example, every 10 minutes.

If new boot output data is included in the received data in step S1003, the new data is received and stored in the sub memory 192. [

In step S1004, the boot output data stored in the display device is then replaced with the received new data.

The booting step of the broadcast receiving apparatus can be divided into a boot loader execution step, an operating system start step, and an application starting step of the broadcast receiving apparatus. The most time-consuming step of these steps is the application step.

According to the above-described embodiments, when boot data is included in the boot loader, the main chip, that is, the chip performing the function of the processor 140 of FIG. 1, is initialized and the boot screen is cleared Accordingly, during booting of the application, the boot screen is not displayed and only the black screen is displayed until the start of the application is completed and the execution screen of the application is displayed. That is, during the boot phase, the boot screen is displayed only during the boot loader execution phase and the operating system start phase, and the boot screen is not displayed during the application start phase, which is actually the longest time.

FIG. 27 shows a screen displayed in a stepwise manner when booting is performed by the method shown in FIG. 13 described above.

The boot screen data is output in step S503, but the output of the boot screen data is stopped, that is, the boot screen is cleared in step S508. In step S509, the execution screen of the application, The blank screen continues until the main screen is displayed.

According to the embodiment of the present invention, the step of temporarily muting or disabling the final output terminal of the processor after the boot screen is displayed and the screen clear of the application starting is included, thereby preventing the boot screen from being cleared . When the final output terminal is disabled, the clear operation of the boot screen is ignored and the previously displayed boot screen remains unchanged.

The processor 140 of the broadcast receiving apparatus 100 of FIG. 1 can be divided into using and not using FRC (Frame Rate Control) according to an embodiment. Accordingly, the method of disabling the final output may vary.

28 shows a configuration of a processor 140 using FRC according to an embodiment of the present invention. The processor 140 may be used as a processor of the broadcast receiving apparatus of FIG. The operation of the other components is the same as described with reference to Fig.

According to an embodiment of the present invention, the input terminal of the FRC unit 271, that is, the output terminal of the image processing unit 147 may be disabled before the screen clearing step during application start after the boot screen is displayed.

29 shows a configuration of a processor 140 that does not use FRC according to an embodiment of the present invention. Likewise, the processor 140 may be used as a processor of the broadcast receiving apparatus of FIG. The processor 140 of Figure 29 synthesizes the input 275 of the video processor 147, that is, the output of the video decoder 144 and the output of the OSD processor 149, between the display of the boot screen and before the start of the application Can be disabled.

It is possible to disable the output terminal as shown in FIG. 28 or 29 at any time after the boot screen is displayed and before the screen clear step during application starting. In this case, the execution command for disabling the output terminal may be inserted into the initialization code of the application, inserted into the OS code, or inserted into the boot loader according to an embodiment of the present invention. 30 to 32 show flowcharts of the embodiments and screen states displayed for each step.

30 shows a booting flowchart when an execution command for disabling video output is inserted into the initialization code of an application according to an embodiment of the present invention.

The remaining steps are the same as those shown in FIG. 13, but immediately after the application execution step S506 is started, the video output is immediately disabled (S506-1).
