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 microcomputer. A CRT control circuit (25) with a built-in character generator operates in response to a command from the control circuit (20). The CRT control circuit (25) generates red to blue character signals (numbers, letters, symbols, etc.) sR, sG, and SB. In addition, the control circuit (20) sends a blanking signal BLK for erasing the television image to the video output circuit (4), and, if necessary, sends an audio control signal so that a buzzer sound will sound at the end of the key operation. sA is sent to the audio control circuit (27).

The AND circuit (19) is for inhibiting the 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 circuit (12).

6) is a pencil-shaped clock start key.

Time display, calendar display, etc. are executed based on instructions from the microcomputer.

FIG. 7 is a display flowchart that explains the above-mentioned image display in relation to key operations.Using this to explain the outline of the operating procedure, first, when the main power is turned on, a normal television image (step a) is displayed. If you press the PPC key here, if the current time is not yet a cent, a predetermined date and time will be superimposed on the TV image, regardless of the actual date (step b). . An example of the date and time display is shown in FIG. 8A. The predetermined date is just one example.

When the current time is set and the clock is already running, the actual date and training are superimposed and displayed (step C). If the current time has not yet been set, step d) to set the current time, and turn on the clock start key (36) (step e). From that point on, the timer program operates and starts counting, and the process moves to step C. .

Instead of operating the clock start key (36),
When the C key is pressed, if the cursor "↓" which is the data setting mark displayed at the "year" position is not in the rloOJ year, the clock will enter the clock start mode in the same way as operating the clock start key (36). At the same time, the current month's calendar is displayed instead of the television image (step f). When the PPC key is pressed from the state of step C, the calendar for the current month is similarly displayed.

When the PPC key is pressed after step f, the channel reservation mode is entered (step g), and a channel reservation image is displayed on the CRT screen in place of the television image.

An example of a reserved image is shown in FIG. To reserve a channel, click
In this example, the timer off time is fixed at about 2 hours from the timer on. Since channel reservation is not directly related to the gist of the present invention, further explanation will be omitted.

If you press the PPC key while reserving a channel or after reserving a channel, a normal TV image will be displayed.

Also, if you press the PPC key in the state of step b or the RPC key in the state of step d with the cursor at the rloOJ position (without operating the clock start key), calendar is displayed (step h). An example of a demonstration calendar is shown in FIG. 8C.

In this way, the year and month displayed in step b are displayed on the demonstration calendar. This demonstration calendar is incremented at intervals of several seconds (2 to 3 seconds), and the calendar for the next month is displayed in sequence. In this case, all the dates on the calendar disappear once, and the next moment a scroll-down display is performed in which the mortars are displayed sequentially starting from the 1st day. The calendar follows the Gregorian calendar, starting from January 0000 to 9999.
It will be displayed until December.

In this way, when the year, month, day, and time are not set, the monthly calendar is automatically turned over, so that it is possible to visually confirm that the current time has not been set. If the PPC key is pressed in this state, the display will be switched to the channel reservation display.

[Problem that the invention seeks to solve]

The above-mentioned TV reception @! On the machine, receive @! By providing a control circuit (20) and a CRT control circuit (25) in the aircraft, the present time, calendar, and channel reservations can be displayed using the television screen, which is extremely convenient.

By the way, it would be even more convenient if such a television receiver had a display function that could display the schedule of the family members who use the television receiver on a daily basis. Of course, even if the TV receiver does not have the above-mentioned display function, if it is possible to display the schedule, it will still be more convenient because it can be used for more purposes than conventional TV receivers.

Therefore, the present invention solves these technical problems by automatically displaying the schedule, especially the current day's schedule.

[Means for solving problems]

In order to achieve the above-mentioned technical problem, the present invention uses a control circuit (20) composed of a microcomputer and a CRT.
A control circuit (25) is provided in the receiver, and a control circuit (20)
By inputting schedule data from the commander (30), the contents of the schedule are displayed on the television screen.

[Effect]

When the schedule data is input manually using the commander (30), the input data is displayed on the television screen (FIG. 3D). After inputting the schedule data, at least when the month and day when the power is turned on matches the month and day of the preset schedule, the contents of the schedule for that day are displayed on the TV screen along with the calendar for that day, for example, by the processing routine shown in Figure 1. , superimposed (Fig. 3F).

〔Example〕

Next, an example of a television receiver according to the present invention,
A case where the present invention is applicable to the television receiver shown in FIG. 5 will be described in detail with reference to FIGS. 1 to 4.

The schedule image to be superimposed on the TV screen, for example, as shown in FIG. It consists of titles (items) M, and six types of symbol marks MS are prepared in this example, as shown in FIGS. 4A to 4F.

The figure A is a symbol mark for a meeting, the figure B is a schedule for driving, the figure C is a schedule for sports (e.g. tennis), the figure is a birthday schedule, and the figure E is a date. schedule for,
F in the figure is a symbol mark indicating a schedule for housework.

These symbol marks MS are all generated within the CRT control circuit (25) based on command data from the microcomputer. In this example, the types of these symbol marks are fixed, but it is also possible to newly set symbol marks based on data input from the commander (30).

In this invention, basically the television receiver αω having the configuration shown in FIG. 5 is used, but the control circuit (20)
The program data to be written to M is different from that in FIG.

FIG. 2 is a display flowchart illustrating such a schedule image display in relation to key operations, and the same parts as in the display flow of FIG. 7 are given the same reference numerals and the explanation thereof will be omitted.

In this invention, when the main power is turned on, the schedule image display step i is started, and the schedule of the day is superimposed on the television image as described later (FIG. 3G). The schedule image for the current day is erased by operating the PPC key, and the display mode of step a is entered.

When adding a schedule display function, the display area of the current month's calendar display in step f or the demonstration calendar display in step h is narrowed, as shown in FIG. 3B. The area created by narrowing the calendar display area is when a schedule has already been set.
Only when a corresponding schedule month exists for the displayed calendar, the schedule contents for that calendar are displayed together with the calendar of the selected month (FIG. 3F).

On the other hand, when a schedule has not yet been posted or when a schedule has not been set for the calendar, the schedule image is not displayed.

If the PPC key is operated in the state of step [or h, and 4 seconds have not elapsed since the last PPC key pressed, the schedule set display mode is entered (step j).

When no schedule is set, the third
As shown in FIG. C, only the symbol mark area MA and the hour/minute separator mark ";" for the month, day, and time are displayed at the upper left of the screen S. At this time, the cursor "↓" is located at the top of the symbol mark area MA, and by pressing the "+J, r-J keys (32) and (33)" at this time, a predetermined symbol mark is selectively displayed.

When you press the ``+'' key (32), the symbol mark MS shown in Figure 4A is displayed in the symbol mark area MA.If you want to change the symbol mark, press the ``+'' key (32).
2) By pressing , the display changes sequentially from B to F in FIG. When the "-" key (33) is pressed, the change display is reversed. After setting the desired symbol mark MS, operate the cursor keys (35). If you do this, the cursor "↓" will move before "Month", so you can use the "+" mentioned above.

Use the "-" keys (32) and (33) to select the month of the schedule to be set, and after selecting the month, use the shift key (35) to move the cursor "↓" in front of "day". ” and set the day using the same procedure.

Such a setting operation is also performed for the schedule setting time, and after setting the time, the title of the schedule is set by moving the cursor rlJ.

Titles are displayed in English or Roman letters. Selection of A to Z is performed using r+J and r-J keys (32) and (33).

For example, if you set the schedule "September 21st Tennis from 10:00 am" (first schedule), the first set schedule SKt will be displayed at the top left of screen S, as shown in the third diagram. Is displayed. Note that the settings of these schedule contents are performed while watching the television screen S.

The contents of the second schedule SK2 are displayed on the right side of the first schedule SK1 (at the top right of the screen S). In the embodiment, schedule contents can be set up to n=6, and an example of the schedule arrangement is shown in Figure 3.

Note that it is also possible to set a plurality of schedules in the same month, and the schedule items may be the same.

If you operate the PPC key after entering the schedule details, this RPC key operation will often occur 4 seconds after the previous PPC key press, so in this case, return to step a and display this schedule instead. A normal TV image is displayed.

In this example, in addition to the schedule display function, it is also possible to input and display the contents of the telephone directory, and if the PPC key is operated again before 4 seconds have passed after selecting the schedule cent mode with the PPC key. , the process moves to step h, and the phone book set mode is entered.

In the phone book cent mode, as shown in Figure 3, the phone book symbol mark MS is displayed at the top left of the screen S, the number of pages is displayed on the right side, and the phone book symbol mark MS is displayed on the left side of the screen S, and the phone book symbol mark MS is displayed on the right side of the phone book symbol mark MS, as shown in Figure 3. (name, number) will be displayed. On one page, the telephone numbers of 8 people are displayed in columns, and in this example, 4 pages, that is, the telephone numbers of 32 people can be stored and displayed.

The cursor "↓" is at the page number, and after specifying the page, use the shift key (35) to move the cursor "↓" to the name field, where the full name is set using the surname (full spelling) and the first letter of the first name in Roman letters. and in the number column, numbers combined with "-" (hyphen) are set as shown in the figure. In this example, up to 14 Roman characters can be entered manually, and numbers can be entered up to 12 digits.

The alphabet ANZ for the name and the numbers 0 to 9 are all selected by the r+J and r-J keys (32) and (33).

When the PPC key is pressed after the telephone directory setting is completed, the process returns to step a.

Now, FIG. 3 is a flowchart showing an example of the display operation according to the present invention according to program data written in the ROM provided in the control circuit (20).

When the program starts, it is determined in step 40 whether the power is on or off. ! When the source is on, the process moves to step 41 and a counter is initialized to one.

This counter is for specifying multiple types of schedules stored in advance. When the initial setting of the counter is completed, the process moves to step 42, and the data of the date set in the first set schedule (the schedule of the first < n = 1) is read from the memory, and this counter is set to N. It is done.

The data N is checked in step 43 to see if it matches the data indicating today's date, and when the respective data match, the process moves to step 44, where the first schedule is superimposed on a part of the television image. The position to be superimposed is, for example, as shown in Figure 3G.
In this example it is the bottom right corner of the screen. Further, as shown in FIG. 3A, the superimposed image is the symbol mark MS indicating the first schedule, the set date, time, and title MT of the schedule.

After superimposing, the process moves to step 45, where the destination counter is incremented by one.

If the data N and the data indicating today's date do not match, the process proceeds to step 45 without passing through step 44. Therefore, in this case, the first schedule is not superimposed on the television screen.

When the counter is incremented, the process moves to step 46, where it is checked whether or not n is 6 or more. If n is 6 or less, the process returns to step 42, and the 2 corresponding to the counter value set in step 45 is incremented. The same operation as described above is repeated by checking whether the date data of the th (n=2) schedule and N match.

For this purpose, the maximum number of schedules that can be set (n=6
) are set in advance, and if, for example, the dates of the 3rd, 4th, and 5th schedules are set to the same month and day, the control routine described above will cause the 3rd, 4th, and 5th schedules to be set in advance. The schedules will be superisoposed on the same screen. An example of the display position in this case is shown in FIG. 3G. The display position of the schedule to be superimposed is determined so as to move from the lower right corner to the lower left corner of the screen.

When it is checked in step 46 that n has become 6 or more, the operation moves to step 47, and the operation of the PPC key is checked. If the PPC key is operated, the schedule image is erased in step 48 and displayed on the screen. returns to the normal display mode where only the TV image is displayed.

If the PPC key is not operated, the schedule image continues to be displayed.

Note that as shown in FIG.
If the step is to determine whether seconds have elapsed, PP
The schedule image is automatically deleted after 30 seconds without operating the C key.

The reason why the determination time for automatic deletion is set to 30 seconds is because it is considered to be a sufficient time to decipher the contents of the schedule after the schedule image is displayed.

Since the display routine shown in FIG. 1 operates every time today's date is changed, the schedule image of that day will always be superimposed on the television image on the set date of the schedule.

Therefore, by turning on the television, the user can check the preset schedule for today while looking at the screen, and there is no risk of missing the schedule.

Note that in the above example, the current day's schedule is superimposed on the date set in the schedule, but tomorrow's schedule is superimposed on the TV image the day before the set date. It is also possible.

Also, since the schedule contents after the corresponding month and day are no longer needed, it is possible to set up a step to determine whether the corresponding month and day have passed and automatically delete the schedule contents when the corresponding month and day have passed. good.

〔Effect of the invention〕

As explained above, according to this invention, if you memorize the schedule from a few days ago or several days before the injury, you can accurately check the schedule for that day by watching TV on the date you set the schedule. This makes it possible to reliably prevent mistakes such as forgetting the day's schedule, which is extremely convenient in practice.

Therefore, the present invention is extremely suitable for application to a television receiver having a display function as shown in FIG.
