Abstract

PURPOSE:To prevent a user from mistaking the normal state for troubles by providing channel reserving and channel block reserving functions and displaying the channel block state and the channel block reservation state. CONSTITUTION:When power is turned on, television pictures are projected; and when a mode changeover switch PPC is depressed, the day of week and the time are displayed over television pictures if a timepiece is set. When the switch PPC is depressed in this state, a channel reservation request is displayed, and the channel block reservation mode is set when the switch PPC is depressed after channel reservation is terminated. After the channel reservation, a television power source is turned on and a reserved channel is selected automatically when the channel reservation time comes after power-off. When the reserved time expires, the television power source is turned off.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates to a television receiver having a program timer function capable of reserving channels and inhibiting channels.

Background Technology and Problems With current television receivers, the current time signal is only transmitted and displayed from the station during specific time periods, so at other times, the current time cannot be checked on the TV screen. It is impossible to do so.

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 channel reservation timer used in VTRs etc. into the television receiver, but in this case, channels are generally reserved only by key operations, so There is no way to check when and which channel you have reserved from what time to what time. In such a case, if the content can be displayed instead of the TV image using the TV screen, 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 undesirable from the educational perspective of young people, such programs are prohibited at the will of the cohabitants, that is, channel blocks.
el block). Broadcast programs that should be blocked in this way are already known before they are broadcast, so even in such cases, you can use the screen display to know when to block which channels and from what time to what time. It is extremely convenient if you can make a reservation.

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.

Further, when the above-mentioned channel block reservation function is provided in a television receiver, it is preferable to display that when a block channel is selected, the channel is in a blocked state.

This is because if a channel cannot be received at all after channel selection, users often mistake it for a malfunction.

Further, even if the channel blocking state is displayed on the CRT in some way, it is more preferable to know which channel is blocked and for how long by simply operating a key.

Purpose of the Invention Therefore, the present invention proposes a television receiver that is equipped with channel reservation and channel block reservation functions, and is also capable of displaying the channel block status and the channel program reservation status during the channel program. to do - to be something.

SUMMARY OF THE INVENTION Therefore, in the present invention, a control device configured with a microcomputer having the functions of a select timer for channel reservation and a block timer for channel programming, that is, a program timer function is provided. When selected, the channel block state is displayed, and when the channel block is in the channel block state, the contents of the channel block can be displayed instead of the channel block display by operating a mode changeover switch.

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 needs and usability mentioned above,
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 program. Ru.

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 a having a program timer function 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 the video output circuit, (5) is the picture tube (C
RT), and (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 the remote control signal and the tuning signal inside the receiver, (14) is a channel tuning voltage forming circuit, and (15) is a PLL that receives this tuning voltage. be. Further, the output of the decoder (13) is supplied to an AC power supply control circuit (17).

(18) is a light receiving element for remote control signals.

Further, (20) is a control circuit having a program timer function for image display, and its main body is a micro combinator. 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 and sq 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 means of a pulse P 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, (3I) is a numeric keypad (10 keys), the PPC key is a remote switching key,
(32) and (33) are "+".

The "-" key, (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. (call the image page "0") (step a)
is displayed, and if you press the PPC key here, the image will be replaced with the image of "Bage 10" if the time has not been set (, the demonstration image that will become the first auxiliary image (step b)
is reflected. FIG. 4A shows an example of this first auxiliary image.

When the clock is set, the day of the week and time (hours and minutes) are displayed superimposed on the TV image (Step C1: This image is called the second 1!!!1 elephant).From this state, for a certain period of time, for example, 3 After seconds, only the day of the week disappears (step d)
), this is because there is little need for constant projection on m1 days. The first auxiliary image and the television image in the clock 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 RPC (Progr
When you press the amablePick Up Center) key, the clock also disappears and the screen returns to the energized 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, and this image is referred to as page "2"). For example, when the manual request for the day of the week and the current time is displayed (step C), when the PPC key is pressed after presetting the day of the week and the current time, a channel reservation request is displayed (step f), and the channel reservation request is displayed (step f). When the PPC key is pressed after the reservation is completed, the channel block reservation mode is entered.

In this case, first the input request for the PIN code (block code) is displayed (step g, this image is set as "Bage 13", and an example of the image content is shown in Figure 4), and after entering the code, press the PPC key to reserve the channel. The outer leather is made (step h). This channel reservation display image is set as page "4", and the image of H-';l-4J 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, when the PPC key is pressed, the TV screen appears, and when the block time comes with the power on, the predetermined channel is 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 password manually.
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 following is an operation procedure showing an example of image display contents, image selection, and preset states. Accordingly, the processing routine is
As shown in FIG. 5, the routine is divided into a display processing routine X, an hour hand (including day of the week) processing routine Y, and a key processing routine 2.

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.
The explanation will be given starting from the state in which the time and other information have not yet been preset in 0). In this case, the PPC page is the θ page, the block flag FB for the channel block is in the 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 B, and it is determined in step 2 that the block flag FB is reset. Therefore, in step 3, a normal television image is displayed.

Since the clock has not yet been set, 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 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 operation status of the PPC key then 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 the steering knob 12. If it is determined in step 12 that the current inner display is the normal TV inner display (theta page), 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.

If it is determined in step 16 that the flag for the PPC page "1" is set, an image corresponding to the PPC page "-1" is displayed in place of the normal TV image. At this time, in step 17, the clock center The condition is determined,
If the clock has not been set, the process moves to step 18 and a demonstration image is displayed. This image contains program features as described above, and initially the clock set mode can be selected. If you want to set 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 "1-1", the process moves to step 20, and the page is 100 pages from the previous PPC key operation. PP for set
It is determined by the steering knob 20 that the time until the C key is operated is within 3 seconds.

If PPC key operation is within 3 seconds, step 2
At step 1, the flux number for PPC page "2" is set, and at step 22, a color flag FC for changing the screen display color to green is set. PP
"C page 1-2" is an image display for clock cents and channel reservation as described above, and when the PPC page is "2", this is determined in step 23 and is displayed in step 24 (1-2). ), the image of PPC page “2” is displayed.

In this case, since it is determined in step 25 that the clock is not set, a request for inputting the current time, etc., is displayed at the bottom of the screen on the steering knob 26 at this time. In the above example, the l-SET CLOCK J display and a predetermined demonstration clock (day of the week, time) display, such as l' 5LIN, 12: OOA
MJ is displayed, and a cursor 1-↓ for manual instruction is displayed at the day of the week display SUN. The input request display color is green as described above.

If a key other than the PPC key, such as a cursor shift key, is operated while the image of PPC page "2" is displayed, this is determined in step IO and the process moves to step 11. This step 11 is a processing routine for setting a clock, 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 hedge is "2", the process moves to step 31, and if the clock is uncented, the process moves to a routine for setting the clock. Therefore, in step 32, 1-+''
or 1--" keys to select the day of the week. r+J
The keys are for changing the day of the week like StJN-4MAN →..., and the F'-J key is for 5UN-43.
This key is used to change the day of the week in the opposite direction like AT →・---, but after selecting the day of the week, press the cursor shift key (cursor key) 1>' or 1 in step 33.
Move the cursor "↓" to the "hour" display position in the time display by operating <" and press "+" in the next step 34.

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

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

When the flag FC is set, this is determined in step 4 shown in FIG. 6A, and the hour hand starts counting in step 5. Also, the cent condition of this watch is on the PPC page “
2", this is determined in step 23, and the clock set state is determined in step (25), and the process moves to step 27, where the rsET CLOCK icon disappears and the cursor rtJ moves to the channel reservation number "1".
”.

When a key is operated in step 37, this is determined in step 10 and the process returns to step 11. However, since the hour hand has already been set at this time, this is determined in 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
Referring again to FIG. 7, "ζ" will be explained.

Steps 41 and 42 are steps for presetting the day of the week, and steps 43 to 46 are steps for presetting "hours" and "minutes." 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 "period (DUR) J," in step 48, set the timer to 1 hour, in step 49, move the cursor "↑" to the rcHJ display position, and in step 50, Preset program channels. Through this series of processing operations, you can determine when, which channel, and from what time to what time.
You can make a reservation. 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 in step 10, and it is determined in step 52 that the currently displayed page is 1°2''. If the PPC key operation after the channel reservation ends 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
At step 55, a flag for PPC page "0" is set, and at step 55, a color flag FW is set to switch the display to a normal television image.

On the other hand, if the PPC key is pressed within 3 seconds after the end of the channel reservation, 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 sent in step 58. Color flag FR is set. The PPC page flag 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 entering a PIN code and confirming it. When the PPC key is pressed for confirmation, 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 "4" is displayed. The flag for is set. When it is determined in step 70 that the PPC page is 14, an image for reservation of the ζ channel block is displayed in step 71.

Also, this PPC page "4" is shown in step 73 of FIG.
Then, the process moves to step 74, a channel block reservation processing routine. In this processing routine, in the same way as channel reservation, 1) press the cursor keys, l -
It is input using the +J, r-J keys, etc., and its processing steps are programmed in the same way as the channel reservation processing step shown 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 "INO", it is not possible to proceed to steps 54 and 55. TV images will be displayed.

After reserving a channel, the phone is turned off, and in this state, when the reserved channel time comes, the reserved time is determined in step 6, and in step 80, the TV power is turned on and the reserved channel is automatically selected. Furthermore, when the reserved time ends, this is determined in step 7, and the television power is turned off in step 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, the channel block image is displayed in place of the TV image. . When the PPC key is pressed 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 l5UNJ and "
SAT”.

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

Furthermore, when you turn on the TV with the clock set, the current TV screen will be displayed, and in this state the PP
When the C key is pressed, the PPC page "1" flag is set in step 15 through steps 10, 12 and 13, so this is determined in step 16, and it is determined in step 17 that the clock has been set, and step 90
Within 3 seconds after displaying ``PPC page 1-1'', in step 91, ``day of the week'' and ``time'' are displayed simultaneously, and after 3 seconds have passed, the process moves to step 92, where only ``time'' is displayed. Ru.

When the pp and c keys are 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 from the display of "1-day of the week" and "1 time", the PP
When the C key is pressed, this is determined in step 20 and the process moves to steps 21 and 22, so that the channel reservation image of PPC page "2" will be displayed.

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

■Specific images from ppc pages 1-2'' to 14'' will be displayed in place of the TV image in sequence each time the PPC key is operated within a certain period of time, and if the RPC key is operated after a certain period of time, The TV image is displayed.

Therefore, it is possible to easily display a specific image that the user wants to view in a short period of time, and if the user wants to return to the original TV image from the selected specific image, wait for a certain period of time and press the PPC key. The operation to return to the original TV image is extremely simple.

(2) Since the basic first image is a television image, adding the above-mentioned functions to a television receiver does not interfere with channel selection, etc.

■ 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, so it is versatile.

■ The second image will display the 1st day of the week and the 1st time, and after presetting these, the timer will start at the timing of switching to channel reservation (when the current time matches the precent time). Since the,
The PPC 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 "time" 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, an accurate time display signal is sent from the station, so it is not necessary in such a case.

■ If neither the clock nor the channel program is set, the cursor "↓" will always be [' S U N
Come to position J. 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 cent specials, the data to be input is displayed on both sides with the manual request display 1゛↑'', so it is easy to confirm the data input position, and it is also possible to distinguish between set data and unset data. Identification becomes easy, and malfunctions of sets such as watches can be reliably prevented.

This is because in the initial state when PPC page "2" is selected, the cursor [↓] is always on the clock cent 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 has a channel block reservation function and its cancellation function, it is possible to reliably cut out 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 rpc page “2” to ppc page r3J, r
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 the present invention, channel reservation and blocking can be performed by providing a control device configured with a microcomputer having a program timer function.

Furthermore, when a blocked channel is selected, it is immediately displayed that the channel is blocked, so even if video and audio are prohibited, the user may mistakenly think that the television receiver is malfunctioning. There's nothing to do.

Furthermore, even when a channel is blocked, the channel block reservation status can be checked by operating the PPC key, which is convenient.

Furthermore, in the present invention, since the display color of the channel block reservation state and the channel block state is changed from the display color of the channel reservation state, it is possible to immediately recognize that the channel is being blocked.
