However, if the number of digital TV products on the market increases, it is expected that there will be a request for a service for a malfunction from a consumer, whether it is a problem of a broadcasting station or a product.

In this case, the after-service agent visits the place where the service is requested and connects the digital TV 110 and the notebook PC 120 with the UART serial cable 130 as shown in FIG. Invoke debug mode.

At this time, the notebook PC 120 executes the debug mode to display the debug main menu.

Accordingly, when the after-service agent selects a menu to be checked in the debug main menu, the notebook PC 120 checks the corresponding function of the digital TV 110 through the UART serial cable 130 and displays the check result on the screen. Done.                         

Therefore, after-sales service personnel checks the check result displayed on the screen of the notebook PC 120 and takes necessary measures.

The contents of the service main menu, PSIP debug menu, and STT (System Time Table) & Time Offset displayed on the screen of the notebook PC 120 by executing the debug mode are as shown in FIG.

That is, in the related art, in order to determine the cause of the problem occurring in the digital TV 110, the cause of the problem is identified by selecting each sub-item of the service main menu.

However, the conventional technology is a debug method of identifying a cause of a problem by connecting a UART serial cable to a service terminal and looking at a terminal such as a notebook PC, but may be a method that can be used to correct bugs in product development, but it is in mass production. And not for after-sales service center service personnel.

That is, conventionally, the following problems are included.

1. In the past, after-sales service personnel need to operate a laptop PC connected with a UART serial cable to the digital TV in order to identify the cause of the problem caused by the digital TV requested for service. There is a problem that must take a certain time before.

2. Conventionally, there is a problem in that the management cost is increased by paying the notebook PC to each after-service personnel.

Therefore, in order to solve the conventional problem, the after-sales service personnel selects a specific key in the digital TV to display a service menu so that the after-sales service personnel can easily find the cause of the problem and take appropriate measures without additional equipment. The purpose of the present invention is to provide a service menu execution device of the digital TV.

The operation and effect of the embodiment of the present invention configured as described above will be described with reference to an exemplary view showing the contents of the service menu of FIG. 4 and an operational flowchart of FIG. 5.

In the present invention, a function such as selection of a broadcast program, image quality and volume adjustment can be executed using a key matrix or a remote controller.

This function is a process similar to the conventional digital TV.

Therefore, in the embodiment of the present invention, only the operations for setting and searching for a specific function will be described in detail.

First, when the after-sales service personnel continuously inputs a specific key using a key input unit 210 such as a key matrix or a remote controller while the digital TV is turned on, the microcomputer 220 may store a service stored in the memory 230. The menu program is executed to output the service menu data to the OSD processor 240.

Here, the reason for combining the plurality of keys consecutively to enter the service menu mode is to prevent the general user from entering the service menu mode by combining arbitrary keys.

In this case, the OSD processor 240 converts the service menu data into a form that can be displayed on the screen of the display unit 260 and outputs the service menu data to the video processor 250.

Therefore, the service menu is displayed on the screen of the display unit 260.

Thereafter, when an after-service agent selects a submenu number of a service menu and a specific item number of the submenu using the key input unit 210, the microcomputer 220 outputs the corresponding item data to the OSD processor 240.                     

Accordingly, the item menu is displayed on the screen of the display unit 260.

Subsequently, when the after-service agent inputs the number of the item to be checked by using the key input unit 210, the microcomputer 220 may operate the chip inspector 280 or the protocol inspector 290 through the UI processor 270. The control checks the operation status of a specific function.

Thereafter, the microcomputer 220 outputs the check result of the operation state of the specific function to the video processor 250 through the OSD processor 240 and displays the result on the screen of the display unit 260.

Therefore, after-sales service personnel can check the inspection result displayed on the screen of the display unit 260 and take appropriate measures.

That is, after-sales service personnel checks the inspection result displayed on the screen of the display unit 260 and then enables or disables the sub-item of the currently selected item to operate a desired function as necessary.

The above-described operation will be described with reference to the exemplary diagram of FIG. 4. When the key input unit 210 continuously presses a specific key example, 'pause key,-,-, 1, 2, 3, confirmation key', the microcomputer ( 220 executes the service menu program stored in the memory 230 to control the OSD processing unit 240 to display the service main menu on the screen of the display unit 260 as shown in FIG.

At this time, if the after-service agent selects the PSIP (Program and System Information Protocol) menu to check the ATSC DTV protocol by inputting '5' at the key input unit 210, the microcomputer 220 is as shown in Fig. 4 (b). The OSD processor 240 is controlled to display the PSIP menu on the screen of the display unit 260.

Here, '1' is a menu for checking the status of the current digital broadcasting channel (major, minor, RF channel number and PSIP presence), and '2' is a time value and day of STT (System Time Table) which is a time table in PSIP. Menu for checking light saving and GPS offset values, '3' is a menu to check the MGT (Master Guide Table) and the table list currently in PSIP and current parsing status, and '4' is built by parsing the PSIP table. The menu for displaying each physical channel of the PSIP database, the virtual channel list linked from it, and the event (broadcast program unit) content included in the virtual channel by dump as a specific key.The number 5 is a PSI table based on the MPEG2 standard without PSIP. '6' is the menu for changing the Time Zone to Korea, North America, etc., and '0' is the key to restore the previous service menu.

Therefore, after-sales service personnel input the key corresponding thereto according to the function to be checked at present so that the microcomputer 220 can check the state of the corresponding function.

That is, the after-service personnel may repeatedly execute the respective items included in the service menu and the sub-menu, check the abnormal state of the digital TV, and restore the normal state.

Therefore, in the present invention, the after-service personnel can take appropriate measures for the after-service request by the user without any additional equipment.

In addition, since the present invention stores the service menu program in the digital TV, it is possible to perform tests, etc. without additional equipment during mass production, thereby improving work efficiency.

In addition, the present invention may implement a service menu to check the status of the encoder or transmission stream developed by the developer of the digital TV encoder or the broadcasting station to confirm only the status of the digital TV.

As described in detail above, the present invention can achieve the following effects.

1. In the present invention, the service menu program is embedded inside the digital TV so that after-sales service personnel can display the service menu on the TV monitor with a simple key operation, access each sub-menu therefrom, monitor the current status, and then take appropriate measures. Therefore, the operation of the notebook is not required as in the prior art, which shortens the training period of the after-sales service personnel, and has the effect of reducing the cost required for training.

2. The present invention has the effect that after-sales service personnel do not need to carry a separate notebook to reduce the management cost for after-sales service.

3. The present invention can access the service main menu for the after-sales service with a simple key operation, so that it is possible to analyze and respond to the problem of the functional failure more systematically, thereby enabling a quick after-sales service.
