DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a broadcast channel setting apparatus according to an embodiment of the present invention. The apparatus includes a ROM 10, a remote controller 20, a key signal receiver 30, a memory 40, A video signal processing unit 60, a water correlation unit 70, a system control unit 80, and an OSD processing unit 90. The video signal processing unit 60,

On the other hand, the ROM 10 sets broadcast channel data assigned to a specific area in the form of a look-up table for each region, and the remote controller 20 also has a predetermined area code input mode, It consists of keys to select and enter codes.

The key signal receiving unit 30 is configured to receive a predetermined infrared signal transmitted from the remote controller 20 and output a signal corresponding thereto and the memory 40 receives the infrared signal from the remote controller 20, The controller 10 reads the broadcast channel data corresponding to the area code from the ROM 10 according to a predetermined control signal, and temporarily stores the broadcast channel data.

On the other hand, when the channel up / down key signal is received in the key signal receiving unit 30, the tuner unit 50 tunes a specific channel among the broadcast channel data stored in the memory 40 according to a predetermined control signal, And the video signal processing unit 60 is configured to demodulate and detect and amplify the video signal output from the tuner unit 50. The video correlation unit 70 is configured to amplify the video signal output from the video signal processing unit 60, And displays the RGB signal output from the RGB signal on the screen in accordance with a predetermined synchronizing signal.

When a channel up / down command is input from the remote controller 20, the system controller 80 outputs a predetermined control signal to tune the broadcast signal to an arbitrary channel set in the memory 40, And the OSD processing unit 90 performs OSD processing on the broadcast channel data output from the system control unit 80 and controls the channel data to be displayed on the water correlation unit 70. [

That is, when a unique code of each area is selected or inputted using the numeric key matrix of the remote controller 20 in the area code input mode, the specific code of each area stored in the ROM 10 The broadcast station channel data is temporarily stored in the memory 40 in a sequential manner.

When the channel up / down signal is inputted from the remote controller 20, the system controller 80 controls the tuning of each broadcasting station stored in the memory 40 and displays the video signal.

The channel data of each broadcasting station according to the predetermined region in the ROM 10 is shown in Table 1 below.

Broadcast stations code Suh (02) Chun Chun (0361) Daejeon (042) Major (053) Week (064) KBS1 9CH 8CH 6CH 8CH 12CH KBS2 7CH 22CH 42CH 38CH 10CH MBC 11CH 10CH 8CH 10CH 7CH SBS 6CH ... ... ... ... EBS 13CH 28CH 39CH 44CH 20CH

As shown in Table 1, the ROM 10 stores channel data of each broadcasting station according to the area, and when the area code (for example, 02) according to each area is inputted as the number key of the remote controller 20, (For example, CH: 9, CH: 7, CH: 11, CH: 6, CH: 13, etc.) are allocated to a specific area.

Meanwhile, the ROM 10 may set not only the VHF channel but also the UHF channel data, and the unique code of each area may be set to a DDD telephone number assigned to the area.

FIG. 2 is a diagram 100 illustrating an OSD of an area code input according to an exemplary embodiment of the present invention. When the remote control unit 20 selects an area code input mode, According to the control signal, the user inputs the area code by using the number keys of the remote controller 20 by referring to the area code table displayed at the lower part of the screen, A predetermined area code may be selected.

FIG. 3 is a flowchart illustrating an operation process of FIG. 1, which will be described with reference to FIGS. 1 and 2. FIG.

First, the broadcasting channel data assigned to a specific area is set in the ROM 10 in table form for each area (S1).

After performing step S1, the system controller 80 checks whether a key signal of a predetermined area code input mode is inputted from the remote controller 20 (S2). If the area code input mode is selected, A code table of each area stored in the area 10 is displayed on the screen and a predetermined area code is selected or inputted (S3). That is, when the key of the area code input mode provided in the remote controller 20 is selected, the character code " Input area code " and the area code table are displayed on the screen as shown in FIG. And the area code is inputted by using the numeric key or the direction key, and the system control unit 80 checks whether the area code is inputted or not.

When the predetermined area code is determined, the system controller 80 reads out the broadcasting channel data corresponding to the determined area code from the ROM 10 and controls the memory 40 to temporarily store the broadcasting channel data in step S4.

When the channel up / down key signal is inputted from the remote controller 20, the system controller 80 controls to sequentially tune the channel data stored in the memory 40, To be displayed on the screen through the OSD processing unit 90 (S5).

Accordingly, as described above, in the present invention, when only a specific area code is input, the channel assigned to the area is automatically read out from the ROM table, so that a child or a senior citizen can easily set a channel assigned to the area easily In the era of liberalization of imports, there is an effect of enhancing market competitiveness due to the differentiation of domestic products.
