Next, the channel line international language method executed by the channel line international language apparatus of the television according to the present invention will be described in detail with reference to the flowchart of FIG.

First, the controller 30 receives the remote control signal for powering on the television in step 50 while waiting for the power on signal from the power button 12 of the remote controller 10 in a non-operation state of the corresponding television. In step 52, the channel number and the volume data stored as last memory data are read and applied to the tuner 36 when the tuning data memory 34 is turned off. Accordingly, the tuner 36 tunes a channel corresponding to the tuning data CV of the last memory channel applied from the control unit 30, and the broadcast signal received from the channel is sent to the IF processing module 38. It is applied and IF converted.

The voice signal of the IF-processed broadcast signal is reproduced at the volume level of the last memory data by the voice processor 40. For example, the voice signal of the remote controller 30 is reproduced with respect to the voice signal reproduced by the voice processor 40. When the volume level set by the volume up / down buttons 18a and 18b or the remote control signal regarding the adjustment of the voice multiple / bass / trouble is transmitted by the voice adjustment button 24, the controller 30 controls the OSD. Generates a control signal CV1 of a volume adjustment level corresponding to the remote control signal while generating an OSD signal of the volume and its control level on the processing unit 44 to be displayed on the CRT device through the image processing unit 42. The audio processing unit 40 is applied to the audio processing unit 40, thereby adjusting the volume of the audio signal processed by the audio processing unit 40. In addition, during the operation of the voice control button 24 of the remote controller 10, the voice multiple mode and / or the tone of the voice signal processed by the voice processor 40 while the display by the OSD signal is performed on the CRT apparatus. The adjustment process (base / trouble, etc.) is performed.

In addition, an image signal of a broadcast signal IF-converted by the IF processing module 38 is applied to the image processing unit 42 to be reproduced, and the screen adjustment button of the remote controller 10 also applies to the video signal. When the remote control signal for adjusting the level of the analog control item is transmitted by (22), the control unit 30 controls the OSD processing unit 44 to generate an OSD signal for the analog control item and the control level. In the state where it is displayed on the CRT apparatus through the image processing unit 42, by applying the control signal CV2 corresponding to the remote control signal to the image processing unit 42, the image processing unit 42 has a color amount. The reproduction processing of the video signal is performed in a state where adjustment of luminance / contrast, color purity and the like is performed.

In addition, the control unit 30 sets the channel step number ('5' in the present invention) set in the channel step number area 32b of the control data memory 32 in step 54 to an internal register (not shown). Will load.

Subsequently, the controller 30 waits for a subsequent remote control signal from the remote controller 10 to be input in step 56, and when the remote control signal is input from the remote controller 10 during the waiting, the controller 30. ) Interprets the remote control signal on the basis of the remote control signal data stored in the control data memory 32. In step 58, the controller 30 determines that the analyzed remote control signal is set to the channel step adjustment mode setting button. It is determined whether or not the signal is a signal for setting the channel step adjustment mode by the operation (28).

As a result of the determination, if it is not the adjustment mode for setting the channel step correction mode (i.e., 'NO' in step 58), the control section 30 proceeds to step 60 and the remote control signal moves up or down the channel step. It is determined whether or not the control signal for channel step interlacing tuning by the operation of the down-interlacing tuning buttons 26a; 26b is performed. As a result of the determination, if it is determined that the control signal is for the channel step interlacing (i.e., 'YES' in step 60), the control unit 30 is present at every operation of the channel step interlacing button 26a; The interlaced tuning is performed from the channel based on the channel change step (ie, '5' step) loaded in step 66 above. That is, the controller 30, for example, when the current viewing channel is '2', when the channel step interlacing button 26a is operated once, the channel number '11' exceeds the channel number '11'. Is set to a channel to be tuned to, and the tuner data corresponding to the channel number '11' is read from the tuner data memory 34 and applied to the tuner 36. Accordingly, the tuner 36 The channel number '11', which is 5 steps greater than the current channel, is tuned. On the other hand, in the one-time operation of the channel step down interlacing tune button 26b, the channel pre-selection of '5' steps from the current channel is performed, and preferably in the channel step interlacing tune performed by the above process. Channels within the '5' step from the current channel can be tuned by the operation of the channel up / down buttons 16a and 16b of the remote controller 10.

On the other hand, if the operation of the channel step up / down intersecting tune buttons 26a; 26b is not detected as a result of the determination in step 60, the process proceeds to step 64 and the channel up / down buttons 16a; 16b or 10 -Normal channel selection processing by the key 20 is executed, or control relating to adjustment of the above-described audio signal or video signal is executed.

On the other hand, if it is determined in step 58 that the channel step adjustment mode setting signal for adjusting the number of channel steps stored in the channel step number area 32b of the control data memory 32 is input (step 58). YES), the control section 30 proceeds to step 66 and sets the channel step adjustment mode, and then receives the number of channel steps set by the 10-key 20 to enter the control data memory 32. After updating and storing in the channel step number area 32b, the above process is controlled to be repeatedly executed when the television is turned on.

On the other hand, while the present invention has been described assuming that the present invention is applied to a channel stored as a memory channel by automatic channel search, the present invention is not limited to the memory channel, but for the entire channel selectable by the corresponding television. Of course, it can also be applied to interlaced countries.

As described above, according to the channel line international language apparatus and method of the television according to the present invention, a channel step designated by the 10-key in a state in which the channel step adjustment mode is set by the channel step adjustment mode setting button added to the remote control unit. Since the interlaced tuning is performed from the current channel on the basis of the above, even if the number of broadcasting stations is greatly increased, the channel tuning time can be significantly shortened compared to the normal channel up / down method.
