Next, the operation of the apparatus for controlling panoramic display of a television according to the present invention having the above-described configuration will be described in detail with reference to an example of the flowchart shown in FIG. 3 and the panoramic screen shown in FIG. 4.

First, the controller 12 waits for input of a remote control signal by the remote controller 10 in a state in which a video / audio signal is reproduced in response to a previous channel selection (eg, last memory channel) in step 40. When the remote control signal is inputted from the remote controller 10, it is determined in step 42 whether the remote control signal is a signal by the operation of the button 10a for setting the function of the panoramic screen display provided on the remote controller 10. Done.

As a result of the determination in step 42, if it is not a remote control signal for setting the display function of the panoramic screen, the controller 12 proceeds to step 44 to perform processing of the video / audio signal corresponding to the remote control signal. do.

That is, when the remote control signal for the tuning of a specific channel is input from the remote controller 10, the controller 12 transmits the channel data for the channel to be tuned by the remote controller 10 to the channel data storage unit 14. The voice signal received from the channel tuned by the tuner 16 is applied to the tuner 16, and the voice IF conversion is performed by a voice processing system (not shown). The video signal of the channel tuned by the volume adjusting function and output from the speaker device (not shown) and tuned by the tuner 16 is detected by the video IF module 18 and then converted into IF and amplified. And is applied to the image multi-screen processor 22.

Then, the video multi-screen processing unit 22 sets the video signal set by the remote controller 10 to the IF converted video signal applied from the video IF module 18 when the display function of the panoramic screen is not set. The video signal is reproduced on the CRT device 25 by processing it based on the control (e.g., brightness, contrast, color amount, etc.) and applying it to the CRT device 26 through the image output unit 24.

On the other hand, when the display of the panoramic screen is designated during the above-described normal video / audio playback processing or by the button 10a for setting the panoramic screen display function of the remote controller 10 in step 42, After setting the execution mode of the panoramic screen display function at 46, it is variable by the 10-key 10b of the remote controller 10 for a predetermined time (approximately 5 sec) from the function setting time of the panoramic screen display by the button 10a. The display timing of the panoramic picture is set awaiting.

While waiting for the variable display timing of the panoramic screen, the controller 12 determines the setting of the variable timing Δt of the panoramic screen display from the 10-key 10b of the remote controller 10 in step 48. If the setting input of the variable timing is not input within the predetermined time, the control proceeds to step 50 where the control signal CT for specifying the display timing (t; for example, 2 to 3 sec) of the panoramic screen that is set in advance is changed to the panoramic screen. It is applied to the control unit 20.

Accordingly, the programmable counter 32 of the panoramic screen variable control unit 20 counts the timing result applied from the timer 30 as the display timing t of the panoramic screen applied from the control unit 12 to display the panoramic screen. The determination unit 36 is applied. In this state, the field extractor 34 extracts a field constituting one frame of the video signal processed by the video multi-screen processor 22 and applies the field extraction result to the panoramic screen determiner 36. do. Accordingly, the panoramic screen determining unit 36 extracts and applies the odd and even fields of the video signal extracted from the field extracting unit 34 at a time of approximately 2 to 3 sec counted by the programmable counter 32. The video multi-screen processing unit comprises a timing determination signal for dividing 9 (that is, an image of one frame is composed of approximately 30 screens, and that one frame is composed of an odd field and an even field of 1/60 sec for interlaced scanning). It is applied to (22).

Accordingly, the video multi-screen processing unit 22 divides the odd field and the even field screen included in t time into 9 to form an image multi-screen (that is, a panoramic screen), and the panoramic screen is an image output unit 24. Is displayed on the CRT device 26 in the form of the screen of FIG. 4, and the panoramic screen divided into nine at a time of approximately 2-3 seconds is displayed on the CRT device 26.

On the other hand, if the variable timing (Δt; for example, 1 sec) for the panoramic display is set and input from the 10-key 10b of the remote controller 10 in step 48, the control unit 12 changes the variable timing. A control signal CT (Δt; 1sec) is applied to the panoramic screen variable control unit 20. Accordingly, the programmable counter 32 of the panoramic screen variable control unit 20 counts the counting result of the timer 30 nine times at the variable timing Δt; 1sec to the panoramic screen determination unit 36. In response, the panoramic screen determination unit 35 determines the timing of dividing the field screen of the video signal applied by the field extraction unit 34 into nine in step 52 and applies it to the image multi-screen processing unit 22. do.

Therefore, the image multi-screen processing unit 22 performs IF conversion processing on the image IF module 18 based on the 9-split timing applied by the panoramic screen determination unit 36 of the panoramic screen variable control unit 20 in step 54. The video signal is divided into nine to form a panoramic screen, and the panoramic screen is displayed on the CRT apparatus 26 via the video output unit 24 in the form of FIG. The overall amount of time of the 9-split screen forming the panoramic screen on the CRT device 26 shown in FIG. Corresponds to the above-described variable timing? T (1 sec).

Subsequently, the control unit 12 determines whether the remote control signal for releasing the panoramic screen display function is inputted by the button 10a of the remote controller 10 in step 56 and remotely controls the releasing of the panoramic screen display function. If a signal is inputted, the panorama function is canceled. If a signal for canceling the panoramic function is not inputted, the process proceeds to step 48 to repeat the subsequent processing.

Accordingly, in the present invention, the variable timing Δt of the panoramic screen display is not limited to the above example but is variably set by the 10-key 10b included in the remote controller 10 to further refine the panoramic screen. Can also be displayed.

As described above, according to the panoramic screen display control apparatus for television according to the present invention, the overall display time can be variably set for the panoramic screen displayed on the CRT apparatus, so that a more detailed panoramic screen can be displayed. .
