In this case, the controller 130 may easily check the display size step of the corresponding area by using the display size information previously stored in the memory 140.

The controller 130 determines whether the checked display size step is an expandable step (S325). At this time, if the display size checked in step S320 is 240 * 130, for example, the controller 130 may know that the checked display size step is one step through the display size information for each step stored in the memory 140. Therefore, it is determined that the checked display size can be enlarged.

If it is determined that the display size of the corresponding area of the display unit 160 is impossible to enlarge in step S325, the controller 130 outputs a message informing of this. At this time, the message may be output as a voice message or a text message.

If it is determined that the display size of the corresponding area of the display unit 160 can be enlarged in step S325, the controller 130 enlarges and displays the display size of the digital broadcast data step by step (S335). That is, if a predetermined key is input when the checked display size step is step 1, the controller 130 enlarges and displays the display size of the corresponding area with the display size of step 2.

In this case, the controller 130 displays, for example, digital broadcast data among pixels constituting the screen of the display unit 160 (eg, pixels of 320 * 320 size) when the display size of the corresponding area is enlarged and displayed. Display by increasing the number of vertical pixels step by step. That is, if the controller 130 displays the digital broadcast data before the 240 horizontal pixels and the 130 vertical pixels of the horizontal pixels and the vertical pixels constituting the display unit 160 screen are enlarged, the process (S335) In this case, the number of 130 vertical pixels displaying digital broadcast data is increased to, for example, 157.

On the other hand, if the predetermined key is not set to enlarge the display size of the corresponding area, that is, the first area or the second area in step S315, the controller 130 displays the inputted predetermined key on the corresponding area. It is checked whether the key is set to reduce the size (S340). The key set to reduce the display size is also preferably one of the keys provided in the user input unit 120.

When a key set to reduce the display size is input, the controller 130 checks the display size step of the corresponding area of the display unit 160 (S345).

The controller 130 determines whether the checked display size step can be reduced (S350). At this time, the control unit 130 is similar to the above-described step in step S325, for example, if the checked display size in step S345 is 157 * 240, the checked through the step-by-step display size information stored in the memory 140 As it can be seen that the display size step is two steps, it is determined that the checked display size can be reduced.

If it is determined that the display size of the corresponding area of the display unit 160 cannot be reduced in step S350, the controller 130 outputs a message informing of this. At this time, the message may be output as a voice message or a text message.

If it is determined that the display size of the corresponding area of the display unit 160 can be reduced in step S350, the controller 130 reduces the display size step by step and displays it. That is, if the checked display size step is two steps, the controller 130 reduces the display size of the corresponding area to display the display size of step 1 and displays the same.

At this time, the controller 130 displays, for example, digital broadcast data among pixels constituting the screen of the display unit 160 (eg, pixels having a size of 320 * 320) when the display size of the corresponding area is reduced and displayed. Display the number of vertical pixels by decreasing them step by step. That is, if 240 horizontal pixels and 157 vertical pixels of the horizontal pixels and the vertical pixels constituting the screen of the display unit 160 display the digital broadcast data, the controller 130 displays the digital broadcast data in step S360. The number of 157 vertical pixels displaying the display is reduced to 130, for example.

On the other hand, if there is a predetermined key input in the display size change mode, the controller 130 may control the display size of the corresponding area to be immediately enlarged and displayed to the full size of the screen of the display unit 160 without going through several steps. In this case, the full size information of the screen of the display unit 160 may be stored in advance in the memory 140.
