The present invention relates to a technology for uniformly displaying channels on an on-screen display. In particular, the present invention relates to displaying a unified broadcast channel on an on-screen (OSD) irrespective of each region, and selecting a desired broadcast channel using one key on a remote controller. And a method and apparatus for setting a broadcast channel on the screen for displaying.

In the general technique of changing a broadcasting channel having two digits using the numeric keys of the remote control, first enter a ten-digit key, and then enter the key of the job again, and display the broadcasting channel on the screen. In this case, only the number of the key currently input is displayed.

As described above, in the conventional channel setting and display method, when a broadcasting channel having a two-digit channel number is set, the channel desired by the channel is set only after pressing the ten-digit key and then pressing the job number. This is inconvenient, and in the display of the channel on the screen, only the currently selected channel is displayed, resulting in displaying a unique channel set for each region, resulting in confusion in recognizing the broadcast channel. .

The present invention has been made in order to solve the above-mentioned deficiency and to set a desired broadcast channel using one key and to display a unified broadcast channel, which will be described in detail with reference to the accompanying drawings.

1 is a broadcast channel control block diagram to which the broadcast channel setting method of the present invention is applied. As shown therein, the microcomputer 1 collectively controls the system, and amplifies the remote control pulse signal to an appropriate level. (1) a remote controller signal amplifier (2) output to the side, a tuning section (3) for controlling the final tuning voltage according to the PLL data input from the microcomputer (1), and selecting a corresponding channel, and the currently tuned data The on-screen integrated device (4) for displaying the number and channel setting of the on-screen menu, and the broadcast program input through the tuner (3), and the input from the on-screen integrated device (4) It consists of a CALTI (5) for displaying the characters to be displayed, and EEPROM (6) for storing the channel setting data input from the microcomputer (1), If the reference to FIG. 2 to FIG. 5 in conjunction with the accompanying action and effect of the present invention constructed as to be described in detail as follows.

When the viewer presses the channel setting key on the remote control, the channel menu screen as shown in FIG. 2 is displayed. In this state, the viewer sets the desired mode by pressing the 1-4 numeric keys on the remote control, and then press " + " Select the data you want to set by increasing / decreasing the channel data using the "-" key, select the memory and skip mode of item 4, and press the "+" and "-" keys to change the channel setting data. It is stored in the pyrom (6).

For example, if you want to directly access the channel by pressing the 11 key on the remote control and the on-screen display in the area where MBC broadcasting comes out from channel 11, first, on the channel setting menu screen, Press key 1 to select REMOCON NUMBER KEY item 1, then press key “+” and “-” on the remote control to set it 11 times.

Press key 2 on the remote control again to select channel 2 setting (CHANNEL) mode, then press key "+" and "-" on the remote control as above to set to 13 and press key 3 on the remote control to turn it on. Select the OSD CHANNEL item and set it to No. 11 using the "+" and "-" keys as above, then press No. 4 key on the remote control to select the memory [MEMORY [+]] or skip [SKIP]. If you press the "+" key while selecting the [-]] item, the above-mentioned data, that is, the 11th key, is stored in the YPIROM (6), and if you press the "-" key, the set data is also saved. In this case, the 11th key of the remote controller is skipped and only the memorized channel data is output when the UP / DOWN key of the remote controller is pressed later.

Therefore, after the viewer sets the channel as described above, pressing the 11 key on the remote control once, MBC broadcasting is selected and 11 is displayed on the screen.

When the viewer presses the automatic channel setting key on the remote control, as shown in FIG. 3, the current channel data is increased from 02 to 69 while the automatic channel setting menu screen is displayed, and the tuning function is performed at this time. If is present, the number of the corresponding channel is automatically stored in address 1 to address 11 of EPI rom 6.

In this case, the OSD channel display is made equal to the number of the current channel, and is displayed as the data from 02 to 69 are raised, and whenever the broadcast channel is tuned by direct access key input from 1 to 11 on the remote controller. The broadcast channel is stored to store up to 11 broadcast channels.

Referring to FIG. 4, a menu screen processing for setting a channel is described below.

When the viewer requests the channel setting menu screen by inputting the channel setting key, after displaying the channel setting menu screen as shown in FIG. 2, check the input key to change the mode of the corresponding item among items 1 to 4. If key 4 is entered, MEMORY (+) and SKIP (-) modes are set, but if key 4 is not entered, first check whether the key "+" is entered. Then, it checks which of the four items shown in FIG. 2 is set and takes the corresponding action.

Here, if the number one REMOCON NUMBER KEY is set, the remote control number key increases the number by one, and then updates the channel and on-screen channel display corresponding to the remote control number key, and the remote control number key next to the number. Update the memory and skip status display.

If two channel items are set among the four items, the number of channels is increased by one, but the on-screen channel display is the same as the number of the set channels, and if three on-screen items are set among the four items, If the number of on-screen channels is increased by one, and four memory and skip items are set among the four items, the channel setting menu setting data is stored in the ypyrom 6 and the current remote control number key is stored. .

On the other hand, if the "+" key is not input and the "-" key is input, it checks which item is set among the four items shown in FIG.

Here, if the number 1 REMOCON NUMBER KEY item is set, the remote control number key decreases the number by one, and then updates the channel and on-screen channel display corresponding to the reduced remote control number key, and the remote control number key number Update the next memory, skip status display.

If two channel items are set among the four items, the number of channels is decreased by one, but the on-screen channel display decreases the number of set channels by one, and if four memory and skip items are set among the four items. , The channel setting menu setting data is stored in the EPIROM (6), and the present remote controller number key is skipped.

Referring to FIG. 5, a menu screen processing for automatically setting a channel will be described below.

Check that the auto channel key is entered, and if that key is entered, check whether the auto channel set menu is displayed again. If it is displayed, clear the auto channel set menu screen, clear the auto channel set mode, and If the channel setting menu is not displayed, the automatic channel setting menu is set and the automatic channel setting menu is displayed.

However, if the automatic channel key is not input, it is again checked whether the automatic channel setting mode is selected, and in the automatic channel setting mode, the current channel is increased from 02 to 69, and the on-screen channel display is also increased from 02 to 69.

If there is a broadcast signal in the current channel, the present channel and the on-screen channel display state corresponding to the current remote control number key are stored in the EPIROM 6, and the corresponding remote control number key is increased by one, and then the channel number. While increasing, find the channel where the release signal exists and repeat the above operation.

As described in detail above, the present invention enables a user to select a desired broadcast channel by pressing a single direct access key and displays a unified broadcast channel on an on-screen screen regardless of a region so that anyone can easily recognize the selected broadcast channel. By providing an automatic channel setting function, it is possible to easily use a plurality of broadcast channels by memory.
