Referring to FIG. 1, the tuner 102 tunes an RF channel under the control of the microprocessor 124 in a broadcast reception signal through the antenna 100. Accordingly, the tuner 102 outputs the channel-selected intermediate frequency (IF) signal, and is converted into a baseband signal by the IF module 104 and output to the channel decoder 106. The channel decoder 106 reproduces the data bit stream by channel decoding the baseband signal input from the IF module 104. The data bit stream reproduced in this manner is separated into audio data, video data, and additional data by the TS (Trans Stream) decoder 108, respectively. The audio data is applied to the audio decoder 110, decoded according to the MPEG standard or the Dolby AC-3 standard, processed by the audio processing and output unit 112, and then output as voice through the speaker 114. The video data is applied to the video decoder 116 and decoded according to the MPEG standard, and applied to the OSG (On Screen Graphic) mixer 118 and merged with the OSG data under the control of the microprocessor 124 to process the video and After processing at the output unit 120 is output on the screen through the water pipe (122). Here, the OSG data is data for the microprocessor 124 to display various types of information on a screen as a graphic or text. The additional data is also applied to the microprocessor 124. Meanwhile, the keypad 130 and the IR receiver 134 are connected to the microprocessor 124 which is the main controller of the HDTV receiver through the user interface 128. The microprocessor 124 performs an operation according to a key button command input from the remote controller 132 through the keypad 130 or the IR receiver 134 according to a program stored in the memory unit 126. The remote control 132 includes a volume control key, a channel tuning key, a menu key, and setting keys which a remote control of an HDTV receiver generally has, and generates and transmits an IR signal when a function key is pressed. 2 shows a layout of a volume control key and a channel selection key generally provided in the remote controller. Meanwhile, the IR signal transmitted from the remote controller 132 is received by the IR receiver 134 and applied to the microprocessor 124 through the user interface 128. The memory unit 126 may include a ROM for storing a control program of the microprocessor 124, a RAM for temporarily storing data according to the execution of the control program of the microprocessor 124, and an EEPROM for storing various reference data. Equipped.

3A and 3B illustrate a flow chart of menu selection adjustment control according to an embodiment of the present invention, and FIG. 4 illustrates an example of menu item display displayed on a screen during menu selection adjustment control according to an embodiment of the present invention. will be.

Hereinafter, a menu selection adjusting method according to an exemplary embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4. First, before describing an embodiment of the present invention, it is assumed that the HDTV receiver shown in FIG. 1 is a TV receiver that supports date and time adjustment, screen adjustment, mute, sleep mode setting, and reservation functions. In this case, the user selects a main menu of any of the above-described various menus (assuming this is a main menu) and adjusts an option item (assuming that this is a submenu) of the selected main menu item. Referring to Figure 3 as follows.

First, the microprocessor 124 checks whether there is a menu key input through the IR receiver 134 in step 150 of FIG. 3A, and proceeds to step 152 if there is an input. In operation 152, the microprocessor 124 controls the OSG mixer 118 to display menu items as shown in FIG. 4 on the display unit 140 of the water pipe 122. It is assumed that the cursor position when the menu item is first displayed on the display unit 140 is located in the main menu 1 in the following description. Therefore, the user can move the cursor up, down, left, and right using only the volume control key and the channel selection key as described below. On the other hand, the microprocessor 124 displaying the menu item proceeds to step 154 and again checks whether there is a key input through the IR receiver 134, and if there is a key input, proceeds to step 156 to determine whether the input key command is a volume control key. Check it. If the result of the test is the volume control key, the microprocessor 124 proceeds to step 158 and moves the cursor along the direction of the input volume control key, that is, (+) and (-) directions, and returns to step 154. Accordingly, the user can position the cursor on one of the plurality of menu items displayed by only operating the volume control key. On the other hand, the microprocessor 124 placing the cursor at a specific main menu item performs step 154 again and proceeds to step 156 when there is a key input from the IR receiver 134 to check whether the input key command is a volume control key. . If the input key command is not the volume control key, the microprocessor 124 proceeds to step 160. In step 160, the microprocessor 124 checks whether the key command input in step 154 is a channel tuning key. If it is determined that the channel tuning key is a channel tuning key, the microprocessor 124 proceeds to step 162 and moves the cursor along the (+) and (-) directions. Accordingly, the cursor is moved up and down so that the user can position the cursor on a desired submenu. If there is a volume control key input in step 164, the microprocessor 124 adjusts the submenu in which the current cursor is located according to the (+) and (-) directions of the input volume control key in step 166. Check if there is a setting key input. If there is an input of the test result setting key, the microprocessor 124 proceeds to step 170 and newly sets the menu item adjusted by the user and ends the menu selection adjusting method according to the embodiment of the present invention. However, if there is no input of the channel selection key, the volume control key, and the setting key while the menu item is displayed on the display unit 140, the microprocessor 124 proceeds to step 172 and counts a predetermined time, and when the counting ends in step 174. The menu selection adjustment method according to the embodiment of the present invention ends.

Therefore, the user can select one of a plurality of menu items with the volume control key as described above, select one of the plurality of submenus belonging to the selected main menu by using the channel selection key, and then select the submenu again with the volume control key. You can adjust the content of.

As described above, since the present invention can selectively adjust each of the menu items supported by the A / V device using only the volume control key and the channel selection key, it is possible to provide the user with the convenience of using the remote control. It also has the advantage of simplifying the design of the remote control by deleting the function keys for selecting each menu item.
