Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a television receiver having a program timer function that allows a clock included in the program timer to be displayed superimposed on the television screen.

BACKGROUND TECHNOLOGY AND PROBLEMS In current television receivers, the current time signal is only transmitted and displayed from the station during a specific time period.
At other times, it is impossible to check the current time on the TV screen.

However, in cases such as when the receiver is turned on, it would be convenient if the current time display could be selected to be superimposed on the television screen.

Furthermore, in the past, even if there was a broadcast program that the user wanted to watch, it was often the case that the user would miss the program because the broadcast time had elapsed or the user forgot the broadcast channel.

In order to eliminate such drawbacks, it is possible to incorporate a timer for reserving channels, which is used in VTRs, etc. into the television receiver, but in this case, channels are generally reserved only by key operations. , there is no way to check when and which channel was reserved from what time to what time. In such a case, if the contents can be displayed instead of the TV image using the inner surface of the TV, it will be extremely convenient because the channel reservation can be visually confirmed, and reservation mistakes can be reliably eliminated.

Furthermore, in recent years, it has become common for young people to enjoy watching television for long periods of time until late at night.

However, since many broadcast programs are broadcast that are not suitable for young people's education, such programs are prohibited at the will of the cohabitants, that is, channel blocks (char +
nel block). Broadcast programs that should be blocked in this way are almost always known before they are broadcast, so even in such cases, you can use the screen display to schedule when and which channels to block. It would be extremely convenient if possible.

By superimposing multiple images such as the current time display, channel reservation, channel block reservation, etc. on the TV screen as described above,
Also, no image display device that can display images in place of the television screen has yet been proposed.

In addition, when displaying the time as described above, it is necessary to preset the clock included in the program timer of the television receiver to the current time, but the first image that displays the television image and the program status of the timer are displayed. When the second image, that is, the time display image, is sequentially and selectively displayed using the mode changeover switch, when the clock included in the program timer is not set to the current time, when this time display image is selected, A display indicating that the current time should be input to this time display image, for example, rsET CL
It would be more convenient to have a display like OCK J because it would allow you to visually check the unpaid status.

In addition to this, it would be more convenient to have a cursor or other display for requesting input, such as a "↑" display, at a predetermined location where the current time should be input, to avoid erroneous input.

OBJECT OF THE INVENTION Therefore, the present invention proposes a television receiver capable of displaying the fact that the current time is to be input and the location where the input is to be made.

SUMMARY OF THE INVENTION Therefore, in the present invention, a control device configured with a microcomputer having a program timer function is provided, and the second image is selected when the current time is not set on the clock included in the program timer. When the current time is inputted, a display indicating that the current time should be entered is displayed on the second image, and a predetermined display such as a cursor to request input is displayed at a predetermined location where the current time should be entered manually. .

Embodiment Next, an example of a television receiver having a program timer function according to the present invention will be explained in detail with reference to FIG. 1 and subsequent figures.

When this invention is applied to a television receiver, the basic first image is a television image, but the number and setting contents of the second and subsequent images are arbitrary.

In this example, considering the above-mentioned convenience and usability,
The second image is set to include the day of the week and time, the third image is set to display the program status of the timer, and the fourth image is set to display the reservation status for the channel block.

In addition to these main images, a plurality of auxiliary images are prepared in this example. The auxiliary image may be a demonstration image used as a preliminary step for displaying the time or the like.

FIG. 1 shows an example of a television receiver OI according to the present invention, in which +11 is a tuner, (2) is a video intermediate frequency amplification circuit, (3) is a video detection circuit, (4) is a video output circuit, ( 5) is a picture tube (CRT), (6) is an audio intermediate frequency amplification circuit, (7) is an output amplifier, (8) is a speaker, (9) is a horizontal and vertical deflection circuit, and (11) is a deflection system. (12) is an electronic tuning circuit, (13) is a decoder that receives remote control signals and channel selection signals inside the receiver, (14) is a channel selection voltage forming circuit, (15)
is a PLL that receives this channel selection voltage. In addition, the output of the decoder (13) is connected to the AC power supply control circuit (17).
supplied to (18) is a light receiving element for remote control signals.

Further, (20) is a control circuit having image display and program timer functions, and its main body is a microcomputer. A CRT control circuit (25) with a built-in character generator operates in response to a command from the control circuit (20). Red and green character signals sR, s are generated from the CRT control circuit (25). Additionally, a blanking signal BLK for erasing the television image is sent from the control circuit (20) to the video output circuit (4), and an audio control signal SA is sent to the video output circuit (4) so that a buzzer sound sounds at the timing of key operation as necessary. is sent to the audio control circuit (27).

The AND circuit (19) is for inhibiting input of a remote control signal by pulse PI when a control signal is being sent from the control circuit (20) to the electronic tuning circuit (12).

FIG. 2 shows an example of the key layout provided on the commander (30). The commander (30) is used for channel selection, power on/off, etc., as well as for presetting the above-mentioned current time. Among the multiple keys, (31) is the numeric keypad (10 keys) 1. PPC key is mode switching key,
(32) and (33) are 1+.”

1-1'' keys, (34) and (35) are left and right shift keys.

In this invention, the time stamp, image display, etc. are performed by a microcomputer. Figure 3 shows the above-mentioned 1st to 4th
This is an explanation of the image display in relation to key operations, and to explain the outline of the operation procedure using this, first, when the power is turned on, a normal TV image (first image, hereinafter referred to as this first image) is displayed. image as page “0”) (step a
) will be displayed, and if you press the PPC key here, if the time has not been set, the demonstration image (step b) will be used as the first auxiliary image instead of the page "0" image.
is reflected. FIG. 4A shows an example of this first auxiliary image.

If the clock is set, the day of the week and time (hours and minutes) are displayed superimposed on the TV image (Step C1 This I!!!I image is referred to as the second image.) From this state, for a certain period of time, for example, 3 After seconds, only the day of the week disappears (step d)
), there is little need to display the day of the week at that time. The first auxiliary image and the television image in the hour hand display state in steps c and d are collectively referred to as page "1." An example of the clock display state is shown in FIG. 4B. In the state of step d, the mode changeover switch PPC (Progra
When you press the mablePick Llp Center) key, the clock also disappears and you return to the current TV image.

If you press the PPC key in the state of step b, you will see a clock displaying the program status of the timer and an image for channel reservation (this is the third image, this image will be referred to as page "2". An example of this is shown) (step e) - First, a request for inputting the day of the week and current time is displayed, and when the PPC key is pressed after presetting the day of the week and current time, a channel reservation request is displayed (step f), and a channel reservation request is displayed. After the PPC key is pressed, the channel block reservation mode is entered.

In this case, first, a request for inputting the if-code (block code) is displayed (step g, this image is displayed on page "3").
", and an example of the image content is shown in Figure 4. ), and when the PPC key is pressed after entering the code, the channel reservation is displayed (step h). This channel reservation display image is called page "4", and the image of page "4" becomes the fourth image. An example of the image content of page "4" is shown in FIG. 4E.

After inputting the channel to be blocked, press the PPC key to display the TV screen, and when the power is on and the program time comes, the specified channel will be blocked (step i).
, an example of the image is shown in FIG. 4F. ).

If you press the PPC key in this state, you will return to step g, and if you want to restore this channel, enter the secret code.
All you have to do is operate the PPC key to display the image in step h and leave the channel block blank.

Note that if the PPC key is pressed within 3 seconds in the state of step C, the process moves to step f.

The above is the image display content, ri! ! This is an operation procedure showing an example of I@ selection and preset state. Therefore, the processing routine consists of the display processing routine X and the clock (
It is divided into a processing routine Y (including days of the week) and a key processing routine Z.

Next, an example of the operation of clock cents, channel reservation, and channel block reservation using the screen display is shown in Figures 6A and B.
This will be explained with reference to the flowchart shown in FIG. For convenience of explanation, a control device (2) consisting of a microcomputer is used.
0), the time and other information will be explained from a state in which the time has not yet been freshened. In this case, the PPC page is page 0, the block flag FB for the channel block is in a reset state, and the color flag FW is set so that the screen display color for the program is white. do.

When the power is turned on and the program starts, it is determined in step 1 that the PPC page is page 0, as shown in FIGS. 6A and 6H, and step 2 determines that the block flag FB is reset. Therefore, in step 3, a normal television image is displayed.

Since the clock has not yet been counted, it is determined in step 4 that the clock flag FC has been reset, so the clock count in step 5 does not start. Similarly, since channel reservation and end r are not set, these are determined in step 6.7.Furthermore, since no channel block reservation has been made, this is determined in step 8, and the block flag FB is reset in step 9. The state remains the same, and then the PPC key operation state changes to step 1.
Determined as 0.

The PPC key is not operated, and the next processing step 11
If no keys other than PPC are operated, the process returns to step 1 and the normal television image continues to be displayed.

On the other hand, if the PPC key is operated after the power is turned on, this is determined in step 10 and the process moves to step 12. If it is determined in step 12 that the current screen display is the normal TV screen display (page 0), the process moves to step 13, and if the block flag FB is not set, the process moves to step 15 to display the PPC page "1". ” flag is set.

When it is determined in step 16 that the flag of "PPC page 11" has been cented, an image corresponding to the PPC page rlJ is displayed in place of the normal television image, but at this time, the clock cent state is determined in step 17. , if the clock is not counting cents, the process moves to step 18 and a demonstration image is displayed. This image contains program features as described above, and the clock set mode is initially available for selection.

If you want to read the clock, press the PPC key.

As a result, the PPC key operation is first determined in step 10, and after it is determined in step 19 that the current PPC page is "1", the process moves to step 20, and the clock cent is changed from the previous PPC key operation. PPC for
It is determined in step 20 that the time until key operation is within 3 seconds.

If PPC key operation is within 3 seconds, step 2
At step 1, a flag for "PPC page 1-2" is set, and at step 22, a color flag FG for changing the screen display color to green is set. PPC page "2" is an image display for clock setting and channel reservation as described above, and when the PPC page is "2", this is determined in step 23 and the image of PPC page "2" is displayed in step 24. is displayed.

In this case, it is determined in step 25 that the clock is not set, so in step 26 a request for inputting the current time, etc. is displayed on the F side of the screen. In the above example, the rSET CLOCK J display and the predetermined demonstration clock (day of the week, time)
For example, r SUN, 12:OOAMJ is displayed, and a cursor "↓" for input instruction is displayed at the day of the week display SUN. The input request display color is green as described above.

When the image of PPC page "2" is displayed, if a key other than the PPC key, such as a cursor shift key, is operated, this is determined in step 10 and the process moves to step 11. This step 11 is a processing routine for clock cents, etc., and an example of the flowchart is shown in FIG.

In this processing routine, first in step 3o, if it is determined that the PPC page is "2", the process moves to step 31, and if the clock is not yet a cent, the process moves to a routine for clock cents. Then, in step 32, the day of the week is selected by operating the "+" or "-" key. The "i ten" key is a key for changing the day of the week like SUN-4MAN→..., and the "1--" key is a key for changing the day of the week like SUN→SAT→...
This key is used to change the day of the week in the opposite direction, as in . After selecting the day of the week, in step 33, operate the cursor shift key (cursor key) ">" or "ri" to change the day of the week to "1 o'clock" in the time display. Move the cursor "↓" to the display position and press l'+J in the next step 34.

Select the hour using the “-” key. At this time, the [+-1 key functions as an increment key, and the "-" key functions as a decrement key.

In the same manner, the time of 1 minute is set in steps 35 and 36, and after the presetting of the day of the week and time is completed, the operation of the cursor key "ri" or the PPC key is determined in step 37. When this happens, a clock flag FC for starting the clock is set in step 38. When these keys are not operated, the precent state is maintained.

When the flag FC is set, this is determined in step 4 shown in FIG. 6A, and the clock starts counting in step 5. In addition, the set condition of this watch is PPC page "
2", this is determined in step 23, and the clock setting status is determined in step (25), and the process moves to step 27, where r SET CLOCK J disappears and the cursor "↑" shows the channel reservation number. Move to +lJ.

When a key is operated in step 37, this is determined in step IO and the process returns to step 11. However, at this time, since the clock has already been counted, this is determined at step 31 shown in FIG. 7, and the process proceeds to a different processing routine from that described above. This processing routine is a processing routine for channel reservation, and
This will be explained with reference to FIG. 7 again.

Steps 41 and 42 are steps for presetting the day of the week, and steps 43 to 46 are steps for presetting the hour and minute.These steps are the same as those for setting the clock, so we will explain them here. is omitted. Next, in step 47, move the cursor "1" to 1-period (DUR) J, in step 48, preset the timer for one hour, and in step 49, move the cursor "1" to 1-period (DUR) J.
J is moved to the rcHJ display position, and the program channel is preset in step 50. Through this series of processing operations, reservations can be made for ``when, which channel, and from what time to what time''. In this example, only three types of program channels can be reserved as shown in FIG. 4E, but the number of reservations is arbitrary.

When the PPC key is pressed after the channel reservation is completed,
This is determined at step IO, and at the same time, it is determined at step 52 that the currently displayed page is "2". Then, if the PPC key operation after the end of the C channel reservation is 3 seconds or more after the end of the key operation in step 50, as a result of the determination in step 53, step 54 is performed.
At step 55, the flag for PPC page "0" is set, and at step 55, the color flag FW is set and the display is switched to a normal television image.

On the other hand, if the PPC key is pressed within 3 seconds after the channel reservation path r, this is determined in step 53, a flag for PPC page "3" is set in step 57, and a flag for PPC page "3" is set in step 58. The color flag FR is set. The flag for PPC page is set to ``PPC page''.
3'' is determined in step 60, the channel block code is displayed in place of the television image in step 61. This code display is red.

In the code display state, a code input request is displayed, and in step 65 of FIG. 7, PPC page 13'' is determined, and in step 66, a password code input processing routine is entered. This processing routine is for manual identification of the PIN code and its i-authentication, and when the PPC key is pressed to confirm this, this is determined in step 10, and the current image display is changed to PP
It is determined in step 67 that the page C is "3",
In step 68, the key operation interval is determined in the same way as in step 53, and if 3 seconds or more have elapsed since the code was input, the screen is switched to the original TV image, otherwise the process moves to step 69 and the PPC page 14 is displayed. flag is cented. If it is determined in step 70 that the PPC page is "4", an image for channel block reservation is displayed in step 71.

Also, your PPC page [°4] is shown in step 7 of Figure 7.
After the determination is made in step 3, the process proceeds to step 74, a channel block reservation processing routine. In this processing routine, as with channel reservation, data on [which channel is to be blocked, from what time to what time on what day of the week] is entered using the cursor keys and r.
It is input using the +J, r-J keys, etc., and its processing steps are programmed in the same way as the processing steps for channel reservation in FIG. Therefore, its explanation will be omitted.

When you press the PPC key after reserving a channel block, the current display page is determined in steps 12, 19, 52, and 67 of Figure 6 A and B, and since both are "NO", it is not necessary to proceed to steps 54 and 55. The TV image will be displayed.

After reserving the channel, the power is turned off, and in this state, when the reserved channel time comes, the reserved time is determined in step 6, the TV power is turned on at the control knob 80, and the reserved channel is automatically selected. Further, when the reservation time ends Y, this is determined in step 7 and the TV power is turned off using the steering knob 81.

If the block channel matches the time zone and day of the week while watching television, this is determined in step 8, and a channel block flag is set in step 82.

When the block flag is set in this way, FIG.
In step 1, it is determined that the PPC page is "0", and in step 2, it is determined that the block flag is set, so in this case, in step 83, an image for the channel block is displayed in place of the TV image. . If you press the PPC key in this block state, the block flag sent state is determined in step 13, so the process moves to step 85, where the flag for PPC page "3" is sent and the channel block reservation state is displayed. . To unblock the channel, just leave the "day of the week" blank. This blank is rsUNJ and r
It exists between sATJ.

When blank is set, it is determined in step 8 that the block time and the channel is not blocked, and as a result, the block flag is reset in step 9, so that the channel block is canceled and the energized television image is displayed.

Furthermore, when you turn on the TV with the clock set, the Tsutomi TV screen will be displayed first, and in this state the PP
When the C key is pressed, the flag for "PPC page 11" is set in step 15 through step 10.
Then, within 3 seconds after the front page of "PPC page 1-1", the "day of the week" and "time" are displayed at the same time in step 91.
After 3 seconds have elapsed, the process moves to step 92 and only "1 time" is displayed.

When the PPC key is pressed while the "time" is displayed, this is determined in step 20 of FIG. 6B, so step 54.
The process moves to step 55, and the display of "time" is erased.

Also, before 3 seconds have passed since the "day of the week" and "time" are displayed, the PPC
When you press the key, step 20 determines this and moves to step 21.22, which causes the PPC page "
2" channel reservation image will be displayed.

The features of the above processing routine will be explained next.

■ By operating the PPC key within a certain period of time, specific images from PPC pages 12 to 1-4 will be displayed in sequence instead of the TV image, and if you operate the PPC key after a certain period of time, , the TV image is displayed.

・For two reasons, it is possible to easily display a specific image that the user wants to see in a short time, and if you want to return to the original TV image from the selected specific image, you can wait for a certain period of time and then display the PPC. The operation of returning to the original TV image is extremely simple, as all you have to do is press the keys.

(2) Since the basic first image is a television image, even if the above-mentioned functions are added to a television receiver, there will be no problem in channel selection, etc.

■ It is versatile because by simply increasing the memory capacity of the microcomputer, it is possible to increase the number of specific images to be displayed on the screen instead of the TV image.

■ The second image displays the "day of the week" and "time," and after presetting these, the timekeeping operation starts at the timing when switching to channel reservation (when the current time matches the preset time). From, P
The PC key can also be used as a timekeeping start key.

Furthermore, since only the display of the "day of the week" can be automatically deleted after a predetermined period of time has elapsed after the start of time measurement, the display will not interfere with the television image. This is because the "day of the week" display does not need to be displayed all the time like the "1 hour" display.

Furthermore, the display of "time" can be deleted at the user's will, which is convenient. For example, in the morning and evening hours, accurate timetable signals are sent from the station, so this is not necessary in such cases.

■ If neither the clock nor the channel program are set, the cursor [↓] will always be at the rsUNJ position. Therefore, it is not possible to reserve a channel until after the clock has passed. Therefore, forgetting to set the clock can be reliably prevented, and the clock, channel reservation time, and day of the week can be accurately matched.

In addition, in the case of clock cents, etc., which data should be entered is displayed on the inside with the manual request display 1-↑], so it is easy to confirm the data input position, and it is also possible to distinguish between cent data and unset data. This makes it easier to identify the items, and it is possible to reliably prevent malfunctions of sets such as watches.

This is because in the initial state when PPC page "2" is selected, the cursor "↓" is always on the hour hand set display side and the program is such that it is impossible to reserve a channel from the beginning.

Since timing starts at the timing when the PPC key or shift key ">" is operated after setting the clock, it becomes very easy to determine the timing to start timing.

All channel reservation status is displayed on the screen, so you can visually check the preset status and avoid making incorrect presets.

- Since it is equipped with a channel block reservation function and its release function, it is possible to reliably capture broadcast programs that are not suitable for children's education.

In this case, channel blocks cannot be reserved or canceled unless a password is entered, so mischief such as changing blocked channels can be reliably avoided.

Also, from “PPC Page 12” to ppc page r3J, [
When the image content is selected for 4J, the screen display color changes from green to red, so the image content can be accurately confirmed.

DETAILED DESCRIPTION OF THE INVENTION As described in detail, in this invention, by providing a control device configured with a microcomputer having a program timer function, when making a channel reservation, etc., an image of the channel reservation etc. is displayed instead of a normal TV image. is displayed, and a message indicating that the current time has to be input is displayed. For example, r
SET CLOCK J and the location to be entered are displayed with a cursor indicating, for example, "↓".

Therefore, according to the present invention, it is possible to easily check the uncented state of the current time, thereby reliably preventing forgetting to set the current time. Furthermore, since the data to be input is displayed on the screen with the input request display 1↑, it is easy to confirm the data input position, and it is also easy to distinguish between set data and unset data. It is possible to reliably prevent malfunctions such as cents.

This is because in the initial state when PPC page "2" is selected, the cursor 1゛↓ is always on the clock set display side.
This is because it is programmed so that channels cannot be reserved from the beginning.

Since timing starts at the timing when the PPC key or shift key ">" is operated after setting the clock, it becomes very easy to determine the timing to start timing.

Since the clock setting status is all displayed on the screen, you can visually check the preset status and avoid unnecessary presets.
