Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device suitable for application to, for example, a television receiver capable of receiving not only general television broadcasting but also satellite broadcasting.

[0002]

2. Description of the Related Art In recent years, in addition to general television broadcasting such as VHF and UHF, a television receiver capable of receiving satellite broadcasting has been proposed.

Such a television receiver has a satellite broadcast receiving section for receiving satellite broadcasts in addition to a tuner for general television broadcasts.

In such a television receiver, after turning on a mechanical switch (which is called a standby state or the like), for example, a main power source can be turned on or off by a remote controller or the like. .

When the main power source is turned on, power is supplied to the tuner for general television broadcasting and the satellite broadcast receiving section respectively, and these perform reception and output operations.
When the main power supply is turned off, the power supply to the tuner for general television broadcasting and the satellite broadcast receiving unit is stopped, respectively, and the receiving and outputting operations thereof are stopped.

Further, in this television receiver, a remote controller or the like is operated to receive a desired reserved program at a desired reserved time, color adjustment, volume adjustment, etc. It can be set.

A desired item among these items is displayed on the screen, for example, and the parameters of the displayed item can be set.

[0008]

By the way, in the television receiver having many setting items as described above, it is desired to simplify the setting operation.

As a method of this simplification, for example, setting items are displayed as a menu on the screen, and desired items are selected from each item of this menu by, for example, moving a cursor,
After the determination, it is conceivable to display an image for the selected item and set parameters and the like on this image.

However, when such a menu image setting method is adopted, particularly when the cursor on the menu image is moved by the remote controller, the remote controller transmits operation data to the television receiver and the menu. Since the cycle for one image is different, it becomes impossible to move the cursor on the menu image one by one with the remote controller,
There is a risk of causing a so-called double jump phenomenon of the cursor.

Further, when such a setting method using a menu image is adopted, the program reservation is executed, for example, when a program reservation for receiving a desired reserved program is made at a desired reserved time. There is a possibility that some setting items may be selected and determined in the menu image, and parameters or the like that affect the operation being executed due to the program reservation may be erroneously changed.

The present invention has been made in view of the above points, and it is possible to reliably and satisfactorily select an item or the like by moving the cursor, and which item is currently being executed for the user. It is an object of the present invention to propose a display device capable of clearly recognizing whether or not it is and at the same time preventing erroneously changing the parameter or the like of the item.

[0013]

The display device of the present invention is, for example,
As shown in FIGS. 1 to 7, the menu screen from the user side

According to the present invention described above, when a screen having a hierarchical structure is displayed, the cursor is sequentially moved. Therefore, the operation of selecting an item or the like by moving the cursor can be performed reliably and satisfactorily. In addition, the item selected by the user can be visually distinguished from other non-selected items, so that it is possible for the user to visually identify which item is currently selected. Therefore, it is possible to prevent accidentally changing the parameter of the item or the like.

On the other hand, the audio processing circuit 7 performs processing such as amplification and other signal processing on the audio signal from the selector 3 and supplies this audio signal to the speaker 9.

Next, the satellite broadcast receiving section 22 will be described. 11 receives an FM television signal in the frequency band of 12 GHz from the active satellite, and receives the received FM television signal in a 1 GHz band by a converter (not shown). First
A parabolic antenna that converts to an intermediate frequency (the same applies to a BS planar antenna), and the 1 GHz intermediate frequency signal received and converted by the antenna 11 is supplied to the BS tuner 12.

The BS tuner 12 selects a signal band from the first intermediate frequency signal in the 1 GHz band from the antenna 11 according to a control signal from the microcomputer 16 (by a tuning operation on the operation panel 18 or the remote controller 20). Then, the second intermediate frequency signal is obtained, FM demodulated, and then supplied to the video processing circuit 13 and the audio processing circuit 14, respectively.

The video processing circuit 13 performs various signal processing on the FM demodulated signal from the BS tuner 12 to obtain a video signal, and supplies this video signal to the selector 3.

The audio processing circuit 14 band-pass filters the TV signal after FM demodulation, and the band-filtered TV signal is 4-phase DPSK (Differential Phase).
eShift Keying) demodulation, various signal processing is performed to obtain an audio signal, and the audio signal is supplied to the selector 3.

The television main body section 10 and the satellite broadcast receiving section 22 are each driven by a power source from a power source circuit 21.

The power supply circuit 21 obtains various drive power supplies from a power supply supplied from a general commercial power supply via the plug 24, and supplies these to each unit according to a control signal from the microcomputer 16.

The power supply circuit 21 is usually (in a so-called standby state in which the original mechanical switch (not shown) is not turned off) is normally operated by the power source converted by the transformer 25.
6, when the switch (main power switch) 15 is turned on, a control signal is supplied to supply power to each unit.

Actually, VHF and UHF television broadcasts, satellite broadcasts, and various external devices (in this example, VT
R23) to enjoy the image or to record the image and sound of the television broadcast or the satellite broadcast on the VTR 23 or the like, the switches of the operation panel 18 (not shown)
Or operating the remote controller 20.

Among the buttons of this remote controller 20,
20a is a power button, and each time the power button 20a is pressed,
For example, an infrared signal from the controller 20 is supplied to the microcomputer 16 via the light receiver 19,
The power supply circuit 2 is controlled by the microcomputer 16.
The power supply to each unit by 1 is started or stopped, and the television receiver is turned on or off.

Similarly, an infrared signal is supplied to the microcomputer 16 via the light receiver 19 by operating the remote controller 20, and the microcomputer 16 which has received the signal performs control according to the signal. .

Reference numeral 20b denotes an input switching button, which is connected to the received video and audio signals from the tuner 2, the received video and audio signals from the BS tuner 12, and the input terminal group 4 each time the input switching button 20b is pressed. External device (VTR
23, etc.) are sequentially selected by the selector 3 under the control of the microcomputer 16, and the selected video signal is input to the video processing circuit and the selected audio signal is input to the audio processing circuit. Each is supplied.

Therefore, each time the input switching button 20b is pressed, an image of a VHF or UHF television broadcast is displayed on the surface of the color picture tube 8 and the output of the audio from the broadcast from the speaker 9 is transmitted to the satellite. The image of the broadcast image on the screen of the color picture tube 8 and the output of the audio of this broadcast from the speaker 9 and the image of the image from an external device such as the VTR 23 on the screen of the color picture tube 8 and the like The audio output from the speaker 9 is sequentially performed.

Reference numeral 20c is a channel switching button, and a signal indicating a large channel number is pressed each time the (+) side is pressed (or pressing time) shown in the figure, and a signal is small each time the (-) side is pressed (or pressing time). A signal indicating the channel number is supplied to the microcomputer 16, respectively.

Therefore, the tuner 2 or the BS tuner 1
Channel selection is performed at 2, and a desired image specified by the channel switching button 20c can be displayed on the surface of the color picture tube 8 and the speaker 9 can output the sound of the desired channel.

A volume button 20d is provided for the microcomputer 1 each time the (+) side shown in the figure is pressed (or the pressing time).
6, the volume data supplied to the voice processing circuit 7 becomes louder, and the volume of the voice output from the speaker 9 becomes louder.

Every time the (-) side is pressed (or pressing time), the volume data supplied from the microcomputer 16 to the audio processing circuit 7 becomes small, and the volume output from the speaker 9 becomes small.

Reference numeral 20e designates a menu button, which is the menu button 2
When 0e is pressed, the microcomputer 16 reads the menu data developed on the internal video RAM (not shown), and the menu data is read as R, G,
The B signal is supplied to the color picture tube 8 through the video processing circuit 6, and is displayed as a menu image on the surface of the picture tube 8.

The data loaded in the video RAM is read from an internal ROM (not shown).

An example of this menu image is shown in FIG.

That is, when the menu button 20e of the remote controller 20 is pressed, the menu screen m as shown in FIG. 2 is displayed on the surface of the color picture tube 8.

In FIG. 2, m3 is a cursor, and m1 is a symbol for making it easier to visually judge the item m2.

A selection / determination roller 20f is used when the above-mentioned menu image m is displayed on the tube surface of the color picture tube 8, and this roller 20f is rotated to one side or the other side so that each menu item m2 is rotated. The item m2 can be selected by locating the cursor m3 to the left of the symbol m1 and the selected item m2 can be determined by pressing the roller 20f.

Further, as shown in FIG. 3, the menu image m
When the item m2 is selected and determined in, the image n of the nth stage is displayed on the tube surface of the color picture tube 8.

In FIG. 3, mb is a symbol for making it easier to visually judge the item (or parameter or the like) m2 for returning to the previous hierarchy, and m3 is a cursor.

For example, the symbol m1 of the item m2 (in this case, "picture quality / sound quality") determined in FIG. 2 becomes the symbol mb of the item m2 for returning to the previous hierarchy in FIG.

Further, the other item m2 is an item, a parameter, or the like in a lower hierarchy. The image n of the nth layer has an item m2 displayed as "return" as shown in FIG.

For example, the roller 20f is rotated in the same manner as described above, the cursor m3 is positioned to the left of the symbol m1 of another desired item (parameter etc.) m2 (not shown), and the item m2 is selected. By pressing 20f, the selected item m2 is determined, and the image n of the nth layer as shown in FIG. 3 is set, and after setting and the like, the cursor m3 is placed on the left side of the symbol mb of the "return" item m2. Is rotated by rotating the roller 20f to select the "return" item m2, and the roller 20f is pressed to display the menu image m shown in FIG. 2 on the tube surface of the color picture tube 8. Can be issued.

Parameter data and the like of each item changed as a result of being operated in such a procedure are stored in a ROM (for example, EE).
PROM) 17.

To stop displaying the menu image m on the color picture tube 8, the menu button 20e is pressed.

In this way, the microcomputer 16 stops outputting the signal of the menu data, so that the menu image m is not displayed on the color picture tube 8.

Now, in the television receiver of this example,
Cursor m3 in the remote controller 20 described above
Roller 2 of the remote controller 20 when moving on the menu screen m or on the image n of the nth layer.
By rotating 0f or pressing the addition button or the subtraction button of the so-called program remote controller, the cursor m3 is surely moved up and down one by one with respect to each item m2, and the item selected by the cursor m3. The color of m2 or the like is set to be different from the colors of the other items m2, and further, for example, the item m2 of the timer is selected and determined from the items m2 shown in FIG. 2 and the image n of the nth layer as shown in FIG. When the reservation setting screen is displayed, while the reservation is being executed, only the item being executed displayed on the reservation setting screen is displayed in a different color from other items. Make it visible.

These will be described below.

First, the movement of the cursor m3 on the menu image m in the remote controller 20 described above and the nth
Referring to the flow chart of FIG. 4, in the case of moving the cursor m3 up and down one by one with respect to the item m2 by rotating the roller 20f of the remote controller 20 when moving on the image n of the layer Explain.

First, in step 100, it is determined whether or not the cursor counter (for example, the counter inside the microcomputer 16) has been changed. If "YES", the process proceeds to step 110, and if "NO", the process returns again. Go to step 100.

That is, the roller 20f of the above-mentioned remote controller 20 (or the same as the (+) or (-) key of a so-called program remote controller or the like in which all the buttons are arranged} is moved in either direction. By arbitrarily rotating it, a value corresponding to the rotation amount is supplied to the microcomputer 16 via the light receiver 19 in a cycle of 45 msec, for example.

In step 110, the value supplied from the remote controller 20, for example, is negative, that is,
It is judged whether it is a downward movement on the image and "YE
If “S”, the process proceeds to step 120, and if “NO”, the process proceeds to step 130.

In step 120, the value of the cursor counter (for example, the counter inside the microcomputer 16) is compared with the previous value (the previous value of the cursor counter) inside the register (for example, the register inside the microcomputer 16), It is determined whether the difference obtained as a result of the comparison is “2” or more, and if “YES”, step 140
If it is "NO", the process proceeds to step 100 again.

In step 130, the value of the cursor counter (for example, the counter inside the microcomputer 16) is compared with the previous value (the previous value of the cursor counter) inside the register (for example, the register inside the microcomputer 16), It is determined whether the difference obtained as a result of the comparison is “2” or more, and if “YES”, step 150
If it is "NO", the process proceeds to step 100 again.

In step 140, the cursor counter is incremented by "1" and this value is stored in the above register. Then, the process proceeds to step 100 again.

In step 150, the cursor counter is incremented by "-1" and this value is stored in the above register. Then, the process proceeds to step 100 again.

The above operation is repeated in the same manner thereafter, and every time the roller 20f of the remote controller 20 is operated,
The cursor m3 can be surely moved one item at a time.

Next, the colors of the item m2 and the symbol m1 selected by the cursor m3 are changed to other items m2 and m1.
A case where the color is different from the color will be described with reference to the flowchart in FIG.

When the menu image m as shown in FIG. 2 is displayed on the tube surface of the color picture tube 8, for example, as shown in FIG. 2, the roller 20f of the remote controller 20 is displayed.
Select "m2" under "Image / Sound Quality" with
When f is pressed, only the item “m2” of “image quality / sound quality” and its symbol m1 are displayed in white, for example, and the other items m2 and these symbols m1 are displayed in gray, for example.

That is, the determined item m2 and this item m
Only the symbol m1 of 2 is colored differently from the symbols m1 of the other items m2 and these other items m2 so that the user can easily understand the item m2 selected and decided by the user.

Now, referring to the flowchart of FIG. 5, first, at step 210, it is judged whether or not the roller 20f of the remote controller 20 is pressed, and if "YES", the routine proceeds to step 220. Then
If “NO”, the process proceeds to step 230.

In step 220, "0" is loaded into the row counter (for example, the counter inside the microcomputer 16). Then, the process proceeds to step 230.

At step 230, the line item of the line counter is displayed. That is, in the menu image m described in FIG. 2 (the same applies to the image n of the nth layer), the item m2 and the symbol m1 selected by the cursor m3.
Other than that, for example, it is displayed in gray, and the item m2 and the symbol m1 selected by the cursor m3 are displayed in white. Then, the process proceeds to step 240.

This method is performed, for example, by changing the R, G, B data in the video RAM inside the microcomputer 16.

In step 240, the line counter is set to "1".
Step forward. Then, the process proceeds to step 250.

At step 260, the value of the line counter is checked to determine whether the item m2 in the menu image m as shown in FIG. 2 is the lowest line. If "YES", the process proceeds to step 260 and " If “NO”, the process proceeds to step 210 again.

In step 260, the row counter is loaded with "0" as in step 220. Then, the process proceeds to step 210 again.

As is clear from this flowchart, for example, in the menu image m as shown in FIG.
When the roller 20f is not pressed, each item m2
Also, the symbol m1 of this item m2 is rewritten on the tube surface in order from the top, for example, R, G, B data on the video RAM line by line at a cycle of about 16.7 msec and reaches the last line on the tube surface. Then, by loading "0" to the row counter, the video R corresponding to the first row is read again.
The R, G, B data on AM is rewritten.

When the roller 20f is pressed, the line counter is forcibly loaded with "0". Therefore, when the roller 20f is pressed, the line indicated by the line counter is not the first line. In both cases, rewriting is performed again from the R, G, B data on the video RAM corresponding to the first row.

Therefore, since the color is constantly rewritten from the upper row to the lower row on the tube surface, for example, the state of FIG. 2, that is, the image quality / sound quality item m2 and its symbol m1 are displayed in white. When the other item m2 and these symbols m1 are displayed in gray and the roller item 20f of the remote controller 20 is pressed after selecting the item m2 of the timer with the cursor m3, for example, Even if the lines other than the lines are rewritten, the video RAM is set at an interval of about 16.7 msec from the item m2 and the symbol m1 of the child screen, which is the first line in this figure.
The corresponding R, G, and B data above was rewritten, and visually, from the top row, gray is gray, white is gray,
Gray changes to gray, gray changes to white, gray changes to gray, and gray changes to gray.

Therefore, the color of the menu image m (or the image n in the nth layer) can be changed visually beautifully and naturally.

Next, among the items m2 shown in FIG.
For example, when the timer item m2 is selected and determined, the program reservation screen is displayed on the image n of the nth layer as shown in FIG. 3, and when the program is reserved, the reservation is executed. In the meantime, a case will be described with reference to the flowchart of FIG. 6 in which only the item under execution displayed on the program reservation screen is displayed in a color different from other items. The reservation setting screen will be described with reference to FIG.

In the reservation setting screen shown in FIG. 7, in the menu image m shown in FIG. 2, the roller 20f of the remote controller (the same applies to the program remote controller and the operation panel 18) 20 is rotated to move the cursor m3 to the timer. Is positioned to the left of the symbol m1 of item m2, and the roller 20f is further pressed to display the image n of the nth layer on the tube surface, and the reservation is made on this image (satellite broadcasting reservation is the same. ) It is an image that can be displayed on the screen when the setting item m2 is selected and determined by the same operation of the remote controller 20 as described above.

The reservation is made by selecting and deciding an item on this reservation setting screen, and then the image n of the nth layer is further selected.
Can be performed by setting the parameters such as the day of the week, the start time, and the channel on the projected image.

As shown in FIG. 7, when this reservation setting screen is displayed, if there is an item m2 ′ currently being executed among the items m2, for example, that item m2 ′ is changed to another item. a color different from m2 (for example, the item m2 ′ being executed is white,
Other items m2 are gray, etc.).

In this way, the item m currently being executed is
It is possible to prevent erroneous operation of other parameters related to 2'and to make the user clearly recognize the current state of the television receiver.

Further, even when the parameter of the item m2 ′ currently being executed cannot be set, the user can clearly recognize why the setting cannot be made.

Now, a flow chart for executing the above operation will be described below with reference to FIG.

First, in step 310, it is determined whether or not the reservation setting screen is being displayed, and if "YES", step 3
20, the process proceeds to step 330 if "NO".

In step 320, the currently executed item m
It is determined whether or not 2'is present. If "YES", the process proceeds to step 340, and if "NO", the process proceeds to step 350.

At step 330, other processing is performed. Then, the process proceeds to step 310 again.

At step 340, the currently executed item m
2 '("2 fire PM 6:00 4" in FIG. 7)
The R, G, B data of the video RAM corresponding to Then, the process proceeds to step 310 again.

At step 350, the R, G, B data of the video RAM corresponding to all the items m2 (including the item m2 'in FIG. 7) are rewritten to the data for making the same color. Then, the process proceeds to step 310 again.

As described above, when the item m2 is being executed when the reservation setting screen is displayed on the screen, only the currently executing item m2 'is colored differently from the other items m2. Since it was displayed, the item currently being executed m2 '
It is possible to prevent erroneous operation of other parameters and the like related to, and it is possible for the user to clearly recognize the current state of the television receiver.

Further, even when the parameter of the item m2 ′ currently being executed cannot be set, the user can clearly recognize why the setting cannot be made.

The present invention is not limited to the above-described embodiments, and it goes without saying that various other configurations can be adopted without departing from the gist of the present invention.

[0100]

According to the invention described above, when a screen having a hierarchical structure is displayed, the cursor is sequentially moved, so that the operation of selecting an item or the like by moving the cursor can be performed reliably and satisfactorily. You can do that, and you can visually distinguish the item that the user is selecting from other unselected items, so you can visually tell the user which item is currently selected. This has the effect of allowing clear recognition and preventing accidental changes of item parameters and the like.
