 The present invention relates to a method of selecting a channel of a video display device. In particular, when a channel is selected by using a numeric key of a remote controller, a user can delete an incorrectly input number even if the user inputs an unwanted numeric key. An apparatus and method are provided.

In general, a remote control is used to remotely control home appliances or information equipment. These remote controllers transmit control signals by wire or wireless to remotely control functions such as televisions, video tape recorders, air conditioners, etc., so that they can be operated remotely without directly operating switches on the operation panel of each device. will be.

These remote controls can also be adjusted by entering a shortcut button that allows you to select only up / down when selecting simple up / down functions such as channel up / down, volume up / down, etc. You can also enter this desired volume directly.

As described above, referring to FIG. 1, a channel operating method of a remote controller according to the related art is described. First, a user inputs a first numeric key (S11).

The input number is recognized as N1 (S12).

In addition, it is determined whether there is an input of another key within a predetermined time (S13).

Subsequently, if there is an input of another key within a predetermined time as a result of the determination (S13), the second input number is recognized as N2 (S14).

In operation S15, the channel selected by the user is calculated by inserting the recognized N1 and N2 into a predetermined formula.

Subsequently, it is determined whether the calculated channel number exceeds 12 (S16).

As a result of the determination (S16), if the calculated channel number does not exceed 12, it is determined whether another key input exists within a predetermined time (S17).

Subsequently, if there is another key input within a predetermined time (S17), the third input number is recognized as N3 (S18).

The channel desired by the user is calculated by applying the first, second and third input numbers N1, N2, and N3 to a predetermined calculation formula (S19).

Subsequently, switching to the calculated channel is performed (S20).

On the other hand, if the determination result (S13), the input of the other key does not exist within a certain time after the first numeric key input is switched to the channel corresponding to the first input numeric key (S21).

In addition, if the channel calculated after inputting up to the second numeric key exceeds 12, the channel is switched to the corresponding channel (S22).

Then, the corresponding image of the switched channel is displayed (S23).

On the other hand, if the user wishes to switch channels, the process returns to step S11 and the steps S11 to S22 are repeated as the user inputs the desired number of channels (S24).

Finally, when the user inputs the power off command, the process ends (S25).

However, since the channel operation method of the remote control according to the related art has no way of correcting when a user presses a numeric key other than the desired number of channels, the switching to another channel or the input channel is completely erased. There was a problem that inconvenience such as having to input again from the beginning.

Hereinafter, a channel operating apparatus and method according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram showing a channel operating apparatus according to the present invention, Figure 3 is a flow chart showing a channel operating method according to the present invention.

In the channel operating apparatus according to the present invention, as shown in FIG. 2, the channel selection unit 100 capable of inputting and modifying the number of channels desired by the user and the channel selected through the channel selection unit 100 are selected. And an image display device 200 for outputting an image and an audio received through the corresponding channel.

Here, the channel selector 100 controls a key input unit 101 for inputting a number for channel selection desired by a user, and a correction when a numeric key is recognized and incorrectly inputted through the key input unit 101. The first control unit 102, the signal transmitting unit 103 for transmitting a signal according to the numeric key recognized by the first control unit 102, and the user request command input through the key input unit 101 It comprises a first storage unit 104 for storing the command value according to.

In addition, the image display device 200 controls the channel switching according to a signal receiving unit 201 for receiving a signal transmitted through the channel selection unit 100 and a command received through the signal receiving unit 201. The second control unit 205, a tuner 202 for tuning the channel selected by the channel selection unit according to the control signal of the second control unit 205, and an image of the channel tuned through the tuner 202. A video signal processor 203 for processing a displayable signal, a display unit 204 for displaying an image processed by the video signal processor 203, and a second menu for storing various menus and data necessary for operation And a storage unit 206.

The operation of the channel operating apparatus according to the present invention configured as described above is as follows.

First, the channel selector 100 includes a remote controller for allowing a user to remotely transmit a desired command. When the power on command is input through the key input unit 101 of the channel selector 100, the image is input. The signal receiver 201 of the display device 200 receives the signal and drives the image display device 200.

In addition, the user selects a desired channel, and a method of selecting a channel is to select a desired channel by inputting a channel up / down command on the key input unit 101 or directly using a numeric key on the key input unit 101. By input the desired channel is selected.

In other words, when the user wants to select a single digit channel, the user selects a desired channel through one numeric key input. If the inputted numeric key is incorrectly input, the user inputs a "clear" key within a preset time. By re-entering the desired number key, you can select the channel number with one digit you want.

In addition, when a user wants to select a channel having a two-digit channel number, the user selects a desired channel through two numeric key inputs, and then sequentially inputs a second numeric key after inputting the first numeric key. In addition, when an unwanted numeric key is input to both the first numeric key input and the second numeric key input, a “erase” key may be input within a preset time period, and a channel may be selected by re-entering a desired number.

Similarly, when a user wants to select a channel having a three-digit channel number, the user selects a desired channel through three numeric key inputs and sequentially inputs first, second and third numeric keys. Accordingly, when an unwanted numeric key is inputted in the first, second and third numeric keys, the desired channel is inputted by inputting the "clear" key within the preset time after inputting the corresponding numeric key and re-entering the desired number. You can choose.

Then, when the user inputs a desired numeric key without any further “erase” command, the first controller 102 may input a code value corresponding to the numeric key input by the user through the signal transmitter 103. And the signal receiving unit 201 of the image display device 200 receives the corresponding key value and transmits the corresponding key value to the second control unit 205 so that the second control unit 205 can select the channel selected by the user. A control command is output to the tuner 202 to be tuned.

Accordingly, the tuner 202 tunes a channel according to the channel number selected by the user according to the control signal of the second control unit 205, and the image signal of the channel tuned through the tuner 202 is the image signal processor. The signal is input to 203 and processed as a displayable signal on the display unit 204.

Here, when the user selects the desired channel by the method of directly inputting the numeric key on the key input unit 101 will be described as an example.

That is, when the user wants to select the channel "13", the image display apparatus 200 is inputted by first inputting "1" among the numeric keys on the key input unit 101 and then sequentially inputting "3". Signal receiving unit 201 sequentially receives the code values for the numbers "1" and "3" from the signal transmitting unit 103 of the channel selector 100, so that the second control unit 205 receives the tuner. A control signal is outputted so that channel 13 is tuned through 202.

However, when the user selects the channel "13", the user should input "1" among the numeric keys on the key input unit 101, but if the user inputs a numeric key other than "1", the user inputs the number on the key input unit 101. By entering the assigned "Erase" key within the preset time, the number "1" can be selected again.

When the number "1" is selected and "3" is to be input, but a number key other than "3" is input, the previously assigned "erase" key on the key input unit 101 is input within a preset time. After that, by inputting "3" again, the user can select the desired channel "13".

Referring to FIG. 3, a channel operating method according to the present invention configured as described above is described first. When a user inputs a first numeric key, the first numeric key is recognized as N1 (S101 to S102).

Then, it is determined whether another key input exists within a preset time after the first numeric key input (S103).

Subsequently, if another key input exists within the preset time (S103), it is determined whether the input key is the "erase" key (S104).

As a result of the determination (S104), if the input key is the erase key, the process returns to the step S101 and re-enter the first numeric key. Is recognized as the second numeric key N2 (S105).

The channel number is calculated by applying the input first numeric key N1 and the second numeric key N2 to the following equation (S106).

Channel = N1 * 10 + N2

Subsequently, it is determined whether the calculated channel number exceeds a preset channel number (S107).

As a result of the determination (S12), if the calculated channel number does not exceed the preset channel number, it is determined whether another key is input within a preset time (S108).

As a result of the determination (S108), it is determined whether the input key is the 'erase' key (S109).

Subsequently, when the result of the determination (S109), when the 'Erase' key is input, the second input number key is erased, the process returns to step S105, and if the 'Erase' key is not entered, the third number key is entered. The input numeric key is recognized as N3, the third numeric key (S110).

The channel number is calculated by applying the first, second and third numeric keys N1, N2 and N3 to the following equation (S111).

Channel = N1 * 100 + N2 * 10 + N3

Subsequently, it is determined whether the 'erase' key is input within the preset time (S112).

As a result of the determination (S112), if the 'Erase' key is input within the preset time, the third inputted numeric key is input again, and if the 'Erase' key is not input, the channel number calculated by Equation 2 is switched. (S113).

In addition, if there is no other key input within the preset time after the first numeric key input, the determination result (S103) is switched to the channel corresponding to the input first numeric key (S114).

On the other hand, when the determination result (S107), the channel number calculated by the equation (1) exceeds the preset channel number is switched to the channel number calculated by the equation (1) (S115).

Then, the switched image of the corresponding channel is displayed (S116).

Subsequently, it is determined whether the user inputs a channel switching command to see another channel (S117).

As a result of the determination (S117), if the user wants to see another channel, the process returns to the step S101. Otherwise, the image of the selected channel is continuously displayed until the user inputs a power off command. (S118).

As described above, in the channel operating apparatus and method according to the present invention, when an unwanted numeric key is pressed while selecting a channel with a numeric key in the related art, it is necessary to input again after completely deleting a channel being switched to or inputting to another channel. The improvement allows the user to correct a numeric key immediately.

As described above, the channel operating apparatus and method according to the present invention have the following effects.

First, in selecting a channel using the numeric keys, if the user inputs an unwanted numeric key, the user can easily select the desired channel as the user can delete it immediately.

Second, the number of key presses up to channel selection can be minimized by correcting according to numeric key input.

Third, since the user's requirements according to channel selection can be immediately reflected, user satisfaction can be improved.
