Illustrate in the present invention to have the running of the channel operating device of this structure below.

Channel selection portion 100 is made of remote controller, and it is used for transmitting the required teleinstruction of user; If by thekeyboard input part 101 ofchannel selection portion 100, the instruction of input opening power, so, thesignal receiving part 201 ofdisplay device 200 will receive after this signal, remove operationimage display device 200 again.

In addition, the user selects own required channel; Select the method for channel at first go on the inputkeyboard input part 101/downlink channel instructs and selects required channel, perhaps directly the numerical key of inputkeyboard input part 101 is selected required channel.

That is to say, when the user wants to select the channel of one digit number, will select required channel by numerical key input once; When the numerical key of input is inputed by mistake, in the time of having set, after input " cancellation " key, import required numerical key again again, thereby can select the channel number of own required one-bit digital.

In addition,, select required channel, after the input first digit key, import the second digit key successively by importing twice numerical key if when the user wants to select the channel of double-digit channel number.In addition, input first digit key and input second digit key if all imported unwanted numerical key, so, remove to import cancel key in the time of having set, re-enter required numeral then, and method is selected required channel whereby.

Identical therewith, if the user wants to select the channel of three figure place channel numbers, need so to select required channel, and import the first, the second, three numerical key successively by importing three numerical keys.For this reason, in input the first, the second, in the process of third digit key, if imported unwanted numerical key, so after this numerical key of input, in the time of having set, the input cancel key re-enters required numerical key then and selects required channel.

First control part 102 if the user has imported required numerical key under the situation that does not have more cancellation instruction, so, will transmit the code data of importing corresponding to the user toimage display 200 by signal transmission unit 103.Thesignal receiving part 201 ofimage display 200 will receive the data of correspondent button, and it is transferred tosecond control part 205; At this moment,second control part 205 is to tuner 202 output control commands, so that allow user-selected channel obtain selecting.

Then,tuner 202 is selected the channel of the channel number of user's appointment according to the control signal ofsecond control part 205; Channel image signal bytuner 202 obtains selecting will be imported into picturesignal handling part 203, be processed into the signal that can obtain showing ondisplay part 204 then.

Here, bright for instance user adopts the numerical key that directly goes on the inputkeyboard input part 101 to select the process of required channel.

If the user will select channel " 13 ", so, will input number keyboard " 1 ", input " 3 " successively then onkeyboard input part 101; Thesignal receiving part 201 ofimage display 200, to receive successively from the relevant numeral " 1 " ofsignal transmission unit 103 transmission ofchannel selection portion 100 and the code data of " 3 ", sosecond control part 205 will allowtuner 202 select channel " 13 " totuner 202 output control signals.

But, when user selected channel " 13 ", should be onkeyboard input part 101 input number keyboard " 1 ", yet going mistakenly to have imported is not other numerical key of " 1 ", so in the time of having set, cancel key on the inputkeyboard input part 101 is so can reselect numeral " 1 ".

Then, if select numeral " 1 " afterwards, should go input " 3 ", but wrong input other numerical key, rather than " 3 ", so in the time of having set, the cancel key on the inputkeyboard input part 101, re-enter " 3 " then, so just can remove the channel " 13 " of selecting the user required.

Below with reference to Fig. 3 channel operation method of the present invention is described.At first the user imports the first digit key, will think N1 (S101～S102) to the first digit key that is transfused to so.

Then, after input first digit key, judge the input (S103) that in the time of having set, whether has other key.

Then, the result of judgement (S103) if there is the input of other key in the time of having set, so just judges that other key that is transfused to is a cancel key.

The result (S104) who judges if the key of input is a cancel key, so just turns back to step (S101), re-enters the first digit key; If not cancel key, so just import the second digit key, and will think second digit key N2 (S105) to it.

Then, first digit key (N1) that receives and second digit key (N2) are updated to following mathematical expression, just can calculate channel number (S106).

[mathematical expression 1]

Channel=N1*10+N2

To judge here whether the channel number that calculates has surpassed the channel number of having set (S107).

The result (S12) who judges if the channel number that calculates does not have to surpass the channel number of having set, so just judges the input (S108) that whether has other key in the time of having set.

Then, judge that the numerical key that is transfused to is cancel key (S109).

Then, the result of judgement (S109) if imported cancel key, will cancel the numerical key of second input so, turn back to step (S105) then; If do not import cancel key, this will be the third digit key of input so, so it is thought third digit key N3 (S110).

Then, will the input first, second, third digit key N1, N2, N3 are updated to following mathematical expression and calculate channel number (S111).

[mathematical expression 2]

Channel=N1*100+N2*10+N3

Judge whether imported cancel key (S112) in the time of having set here.

The result (S112) who judges if imported cancel key in the time of having set, will re-enter the third digit key so; If do not import cancel key, so just be transformed into by mathematical expression 2 and calculate channel number (S113).

In addition, judged result (S103) if after the input first digit key, in the time of having set, do not have the input of other key, so just is transformed into the channel (S114) corresponding to the first digit key.

In addition, the result of judgement (S107) if the channel number that calculates by mathematical expression 1 surpasses the channel number of having set, so just is transformed on the channel of the channel number that calculates by mathematical expression 1 (S115).

Then, will show corresponding to the channel image that is converted (S116).

Then, judge whether the user has imported the conversion instruction (S117) of wanting to see other channel.

The result (S117) who judges when the user wants to see other channel, just turns back to step (S101); If not, will continue to show the image of selected channel so, until till when importing the instruction of powered-down (S118) by the user.

As mentioned above, in the present invention, channel operating device and method thereof have been improved existing problem in the conventional art, promptly utilizing numerical key to select in the process of channel, if supress unwanted numerical key, so need deletion fully will remove other channel changed or the channel of importing, and then go the problem imported.Therefore, though user error imported numerical key, also can go at once to revise.
