Is an input signal discrimination unit for discriminating a key input signal inputted after being operated by the key, and 32 is displayed on the screen to enable the user to easily grasp the control state according to the key input signal from the key input unit 22. An OSD memory for storing OSD texts and OSD data for display screens of all broadcasting stations. 30 is stored in the OSD memory 32 according to the control signal of the microcomputer 26 below. An OSD controller which processes OSD text and outputs the same to the RGB output unit 18. In the RGB output unit 18, when the OSD text signal is input from the OSD controller 30, the OSD text signal is output to the image. It is mixed with the RGB signal according to the television image input from the signal processor 18 and output to the CRT 20.

Reference numeral 26 denotes a microcomputer for controlling the overall operation of the television apparatus in accordance with the key input signal from the key input unit 22 inputted through the input signal discriminating unit 24. When the full-window key of the key input unit 22 is operated, the power supply unit is controlled to be in a power supply state, and the television output state data is read from a last memory (not shown) in which the television output state at the last operation is stored. On the basis of the data, overall control (i.e., control of applying the channel tuning data to the tuner 12 to tune the television broadcast, etc.) is performed. Then, the key operation in the key input section 22 carries OSD character display. In the case of a control input, by outputting a control signal to the OSD control unit 30, the OSD control unit 30 reads out the corresponding character data stored in the OSD memory 32 to the RGB output unit 18. To control the output.

In the present invention, as shown in FIG. 2, the key input unit 22 is provided with a broadcasting station name input mode key for setting a broadcasting station name input mode, and includes a memory for storing the broadcasting station name for each broadcasting channel. 28) is installed. When the broadcasting station name input mode key is operated, the microcomputer 26 performs OSD signal processing on the display screen data of all broadcasting station names stored in the OSD memory 32 and displays them on the screen as shown in FIG. If a predetermined broadcast station name is selected, the selected broadcast station name is allocated to the currently tuned channel and stored in the memory 28. If there is a channel change input from the key input unit 22, the memory 28 ), The broadcasting station name for the currently tuned channel is read out, and the OSD signal is processed to display on the screen as shown in FIG.

Next, a broadcasting station name display apparatus for a television according to the present invention configured as described above will be described in detail with reference to the flowchart shown in FIG.

That is, in step S1, when the power key is operated from the key input unit 22, the microcomputer 26 controls the power unit (not shown) to control the external power to be applied to the television system and to the last memory (not shown). The final television output state data stored is read out, and the final channel tuning data is applied to the tuner 12 to tune the corresponding television broadcast, and the IF amplifier 14, the video signal processor 16, and the RGB output unit 18 are tuned. ) Is output to the CRT 20 via step S2.

Thereafter, in step S3, the microcomputer 26 determines whether the broadcasting station name input mode key has been operated from the key input unit 22, and if it has been operated, displays the display screen data of all broadcasting station names stored in the OSD memory 32 by OSD signal processing. As shown in Fig. 3A, the display is displayed on the screen and the internal timer is activated (step S4).

Subsequently, if a predetermined broadcast station name is selected in step S5, the selected broadcast station name is allocated to the currently tuned channel and stored in the memory 28 (step S6). In step S7, the OSD screen for inputting the broadcast station name is cleared. The process then returns to the above-described step S3.

If the predetermined broadcast station name is not selected in step S5, it is determined in step S8 whether the operation time of the internal timer has reached a predetermined set time, and if so, the process proceeds to step S7 described above to clear the broadcast station name input OSD screen. If it has not reached, the process returns to the above-described step S5.

On the other hand, if the broadcasting station name input mode key is not operated from the key input unit 22 as a result of the determination in step S3, then control proceeds to step S9 to determine whether a channel change input from the key input unit 22 is made. In this case, if it is determined that the channel change input is made, the microcomputer 26 accesses the memory 28 in step S10 to determine whether a broadcast station name corresponding to a channel currently tuned and tuned is stored. As a result of the determination in step S10, as the wonder microcomputer 26 storing the broadcasting station name outputs the broadcasting station name as a control signal to the OSD control unit 30, the OSD control unit 32 accesses the OSD memory 32. By reading the broadcast station name OSD text data corresponding to the broadcast station name data and outputting it to the RGB output unit 18, the broadcast station name corresponding to the channel currently being broadcast on the screen is displayed as the OSD text, and then the control proceeds to the next step. Proceed to S12.

On the other hand, when the channel change is not made as a result of the determination in step S9 and when the broadcasting station name is not stored as a result of the determination in step S10, control proceeds directly to step S12.

In the step S12, it is determined whether the power-off input is made by the power key from the key input unit 22, and when the power-off input is not made, the process returns to the step S3, while the control is performed when the power-off input is made. Proceeding to step S13, the current television output states such as the current tune channel, the volume level, the contrast level, and the like are stored in the last memory to terminate all the control.
