Next, the general video / audio signal reproduction processing operation of the television having the above-described configuration will be briefly described.

When a control signal for power-on and channel selection is input from the control signal input unit 1, the control unit 2 turns on the power of the television based on the control signal and is a channel to be tuned to. When the preset voltage VT corresponding to the readout is read by the channel data storage unit 3 and the corresponding tuner voltage VT is applied to the tuner 5, the tuner 5 is identified by the tuner voltage VT. Perform channel tuning for the channel.

Subsequently, the tuner 5 applies the broadcast signal for the selected channel to the IF amplifier 6, and the IF amplifier 6 amplifies the IF signal of the corresponding broadcast signal and then connects the SIF to the rear end. It is applied to the detector 7 and the PIF detector 10.

The audio signal of the channel is output.

In addition, the PIF detector 10 detects only the PIF (image intermediate frequency) signal from the IF signal output from the IF amplifier 6 and applies it to the image signal processor 11 connected to the rear stage. The signal processor 11 performs image processing such as color / brightness / tint / sharpness on the PIF signal under the control of the controller 2, and performs the insertion process of the OSD text signal applied from the OSD processor 4. Then, the video signal corresponding thereto is applied to the video amplifier 12 connected to the rear end, and the video amplifier 32 amplifies the video signal and then applies the video signal to the CRT. Is played back.

First, a channel editing operation according to an embodiment of the present invention will be described in detail with reference to the flowchart shown in FIG.

First, if the channel edit mode is set as the channel edit key 1e configured in the control signal input unit 1 is operated and the control signal corresponding thereto is applied to the control unit 12 (step 30), the control unit 4 The OSD text signal is generated by applying a predetermined control signal to the OSD processor 4 and the image signal processor 11 to output the OSD screen according to the channel editing guide on the CRT screen. In addition, the OSD text signal is inserted into the screen by the video signal processor 11 to output the OSD screen according to the channel editing guide as shown in FIG. 4A on the CRT screen (step 31). At this time, the OSD screen displayed as the CRT screen is assigned a specific genre (ie, 1.movie/2.local broadcast / 3.showpro / ·· / 10. Mainly watching broadcast) for each edit number.

On the other hand, in response to the editing number output on the CRT screen, when the viewer manipulates a specific number key, for example, '4' and inputs an editing number corresponding to the editing number, that is, '4' (step 32), the control unit 2 By applying a predetermined control signal to the OSD processing unit 4 and the image signal processing unit 11 so that the OSD text signal for outputting the OSD screen according to the channel registration guide on the CRT screen by the OSD processing unit 4 is generated. In addition, the OSD text signal is inserted and processed on the screen by the image signal processing unit 11 so that the OSD screen according to the channel registration guide as shown in FIG. 4B is output on the CRT screen (step 31).

In such a state, when the viewer sequentially inputs a plurality of channels, for example, '6, 7, 9, 11', the OSD characters for the input channel are displayed on the CRT screen as shown in FIG. 34).

Then, the controller 2 determines whether the channel edit mode set in step 30 is released (step 35). If the channel edit mode is not canceled (NO in step 35), the channel edit mode is determined. After the predetermined time has elapsed in the state that the channel edit mode is not canceled, the process proceeds to step 31 and re-outputs the OSD screen according to the channel editing guide. .

However, on the contrary, when the channel edit key 1e signal is input again from the control signal input unit 1, the controller 2 releases the channel edit mode set in step 30 based on the channel edit key 1e signal. If it is determined (YES in step 35) that the channel information registered in step 34 is stored in the EEPROM 13 (step 37), the channel editing operation is terminated.

Next, the operation of the channel editing method in the television according to an embodiment of the present invention will be described in detail with reference to the flowchart shown in FIG.

First, the control unit 2 performs a reproduction processing operation on a broadcast signal received through an antenna based on a power on signal and a channel tuning signal input from the control signal input unit 1 (step 40). It is determined whether the simple station key 1f signal is input from the signal input unit 1 (step 41). If the result of the determination is that the simple station key 1f signal is not input from the control signal input unit 1 (step) NO at 41). The process proceeds to step 40 to continuously perform the playback processing operation on the TV broadcast signal.

On the contrary, in the state in which the viewer performs the channel editing operation, the simple tuning key 1f configured in the control signal input unit 1 is operated to perform the up / down adjustment of the channel for the channel registered in the specific channel group. As a result, when the simple selection key 1f signal is inputted to the control unit 2 (YES in step 41), the control unit 2 waits for input of an edit number from the control signal input unit 1.

Thereafter, after the viewer inputs a predetermined edit number, for example, '10' using the 10-key configured in the control signal input unit 1 (step 42), the viewer channels up the control signal input unit 1. When the up / down adjustment channel is operated by operating the up / down adjustment key 1c (step 43), the controller 2 controls the EEPROM 13 based on the key signal according to the operation of the channel up / down adjustment key 1c. Channel up / down is tuned based on the channel information registered to the channel group designated by the edit number '10' stored in step (step 44).

That is, if the channel information stored in the EEPROM 13 is '6,7,9,11', for example, the channel up / down adjustment key configured in the control signal input unit 1 in the state where the viewing channel is '7'. When the channel down adjustment signal is inputted from (1c), the control unit 2 reads out channel data for the '6' channel from the channel data storage unit 3 and recalls the preset voltage VT corresponding to the channel data. By applying to the tuner 5, the channel # 6 tuned down from the current channel '7' is tuned. Accordingly, the channel tuning operation is performed in the order of '6 → 7 → 9 → 11' based on the number of times the viewer operates the channel up / down key 1c.

As described above, according to the channel editing method of a television according to an embodiment of the present invention, a user selects a channel group in a state where the viewer has previously edited a plurality of channels into one channel group, and then ups / downs the channel. When the operation is performed, the up / down operation of the channel is performed in the channel edited by the channel group, so that the user does not have to check the channel information in order to select a channel of a specific genre, and also selects a specific numeric key during channel selection. This eliminates the hassle of manually manipulating.
