In the channel map editing method according to the present invention, when a channel editing function is selected by a user, channels previously stored in a memory such as an EEPROM are displayed on the OSD screen in the form of a channel map as shown in FIG. 1. In this case, the channel map is displayed in a rectangular checkerboard shape, so that the user can easily select a channel region including channels to be edited.

However, FIG. 1 exemplarily shows a screen displaying a channel map, and the screen displaying the channel map may be configured in various forms.

First embodiment

Reference numeral 100 in FIG. 1 denotes a channel region in which a plurality of consecutive multiple channels are selected by a user.

Hereinafter, a channel map editing method according to an embodiment of the present invention will be described in detail with reference to FIG. 2.

First, when a channel editing function is selected from the user through the OSD menu (step 200), the channel map previously stored in the memory is displayed on the screen in the OSD form (step 210). At this time, in order to allow the user to easily select the desired channel region, it is preferable to display a predetermined number of channel maps in rows and columns on the screen like a tile. Further, in the displayed channel map, certain channels are highlighted. Next, wait for the keystroke from the user.

If a moving key for moving up, down, left, and right, such as an arrow button, is input from the user while the channel map is displayed in step 210, the highlighted channel is changed according to the moving key. Next, when one of the editing keys is input from the user (step 220), a corresponding editing operation is performed on one channel highlighted on the current channel map, that is, one selected channel (step 260).

However, when the user inputs the multi selection start key through the OSD menu in step 210 (step 230), the user may select a channel area including a plurality of channels to be edited using the move key (step 240). At this time, when the multi selection is started, the user selects the start channel and the end channel from the channel map by using the move key and the select key. As a result, all the channels from the start channel to the end channel are selected, and a channel region consisting of the selected channels is set.

In operation 240, when a channel region for channels to be edited is selected from a channel map on an OSD screen by a user, and a button related to an editing function is input, corresponding editing operations are simultaneously performed on channels in the selected channel region. (Step 250).

For example, when editing at least one or more channels simultaneously, the channel editing function is selected through an OSD menu. In the channel map displayed on the OSD screen according to the selection of the channel editing function, after inputting the multi selection start key, the start channel and the end channel are selected using the navigation keys and the selection key to set the desired channel area for editing. . When the setting of the desired channel region is completed, by inputting a button related to a desired editing function, the corresponding editing operation is simultaneously performed on the plurality of set channels.

3 is a block diagram showing the internal structure of a television receiver for performing a channel map editing method according to the present invention.

3, the function of each block of the television on which the channel map editing method according to the present invention is executed will be described.

First, when a channel editing function is selected by the user, the microcomputer 310 recognizes this and transmits the corresponding key value to the CPU 300. Next, the CPU 300 causes the image display processor 340 (VDP) to bring up the channel map OSD from the dynamic memory 310 (DRAM). Next, the VDP 340 stores the channel map OSD read from the DRAM 340 in the SDRAM 350. Next, the SDRAM 350 displays the channel map OSD on the screen by outputting the channel map OSD as an R, G, B image signal or a Y, Cb, Cr signal.

After the channel map is displayed on the screen as described above, when the user edits the channel, the old channel map data stored in the EEPROM 320 is deleted and the data for the newly edited channel is stored.

According to the present embodiment, editing can be performed simultaneously on a plurality of consecutive channels.
