FIG. 7 is a display flowchart for explaining the above-mentioned image display in relation to the key operation. To explain the outline of the operation procedure using this, first, a normal TV image (step a) is displayed when the main power is turned on, When the PPC key is pressed here, if the current time is not set, the predetermined date and time are superimposed on the television image regardless of the actual date, etc. (step b). . An example of the date and time display is shown in FIG. 8A. The predetermined date is only an example.

When the current time is set and the clock is already running, the actual date and time are superimposed and displayed (step c). If the current time is not set and the current time is set (step d) and the clock start key (36) is turned on (step e), the timer program will operate from that point to start the clock and go to step c. Move. When the PPC key is pressed instead of operating the clock start key (36), when the cursor of "↓" which is the data setting mark displayed at the "year" position is not in the "100" age, the clock start is started. Similar to the operation of the key (36), the clock start mode is set, and the calendar of the current month is displayed instead of the television image (step f). PP from step c
Pressing the C key will display the calendar for the current month as well.

When the PPC key is pressed after step f, the channel reservation mode is set (step g), and the channel reservation image is displayed on the CRT screen instead of the television image. An example of the reserved image is shown in FIG. 8B. The channel reservation is "what day of the week and what channel", and the timer off time is fixed to about 2 hours after the timer is turned on in this example. Since the channel reservation is not directly related to the gist of the present invention, further description will be omitted.

When the PPC key is pressed during channel reservation or after channel reservation is completed, a normal television image is displayed.

When the PPC key is pressed in the state of step b, or when the cursor is in the position of the "100" age (the state where the clock start key is not operated) in the state of step d, the PPC key is pressed, respectively. The demonstration calendar is displayed (step h). An example of a calendar for demonstration is shown in FIG. 8C.

In this way, the year and month displayed in step b are displayed on the demo calendar. Then, this demo calendar is incremented at intervals of several seconds (2 to 3 seconds) and the calendar of the next month is sequentially displayed. In this case, all the dates on the calendar are temporarily erased, and the scroll-down display is performed such that the days are sequentially displayed from the first day at the next moment. The calendar is displayed from January 0000 to December 9999 according to the Gregory calendar.

As described above, when the year, month, day and time are not set, the monthly calendar is automatically turned, and the unset state at the current time can be visually confirmed. When the PPC key is pressed in this state, the channel reservation display is switched.

[Problems to be solved by the invention]

In the above-mentioned television receiver, the control circuit (2
0) and the CRT control circuit (25), the present time display, calendar display, and channel reservation display can be performed using the television screen, which is extremely convenient.

By the way, it would be more convenient if such a television receiver had a display function capable of displaying a schedule of a family member who uses the television receiver daily. Of course, even if the display function as described above is not provided, if the schedule display is possible, it can be used more versatile than the conventional receiver, and thus it is convenient.

Therefore, the present invention solves such a technical problem, and is adapted to automatically display a schedule display, particularly, for example, a schedule of the day.

[Means for solving problems]

In order to solve the above-mentioned technical problem, in the present invention, a control circuit (20) and a CRT control circuit (25) each composed of a microcomputer are provided in a receiver, and the control circuit (20) is connected to a commander (30). The schedule contents are displayed on the TV screen by inputting the schedule data.

[Action]

When inputting the schedule data using the commander (30), the input data is displayed on the television screen (Fig. 3D). After inputting the schedule data, if at least the date when the power is turned on matches the date of the preset schedule, the processing routine of FIG. , Super In Whores (Figure 3F).

〔Example〕

Then, an example of the television receiver according to the present invention,
The case of application to the television receiver shown in FIG. 5 will be described in detail with reference to FIGS.

The schedule image to be superimposed on the television screen is, for example, as shown in FIG. 3A, a symbol mark Ms indicating the type of schedule, a date (month, day), time (hours and minutes) of the schedule, and a schedule. The title (item) M _T and six types of symbol marks M _S are prepared in this example as shown in FIGS.

FIG. A is a symbol mark for meeting, and similarly, FIG. B is a schedule for sports (for example, tennis), FIG. C is a driving schedule, FIG. E is a date schedule, and FIG. F is the same. Is a symbol mark indicating a schedule for housework.

All of these symbol marks M _S are generated in the CRT control circuit (25) based on the command data of the microcomputer. Although the types of these symbol marks are fixed in this example, it is also possible to newly set symbol marks based on the data input of the commander (30).

In the present invention, the television receiver (10) having the structure shown in FIG. 5 is basically used, but the program data to be written in the ROM of the control circuit (20) is different from that shown in FIG. .

FIG. 2 is a display flowchart for explaining such an image display for a schedule in relation to key operations. The same parts as those in the display flow of FIG. 7 are designated by the same reference numerals and the description thereof will be omitted.

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

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

On the other hand, when the schedule is not set yet, or when the schedule is not set in the calendar month, the schedule image is not displayed.

When the PPC key is operated in the state of step f or h and the operation of this PPC key has not elapsed 4 seconds from the PPC key pressed immediately before, the schedule set display mode is set (step j). When no schedule is completely set, as shown in FIG. 3 C, hour and minute separator mark symbol Elijah M _A and date and time ":" only is displayed in the upper left portion of the screen S. At this time the cursor "↓" is located at the top of the symbol Elijah M _A, this time "+", "-" key (32), are selectively displayed predetermined symbol by pressing (33).

When the “+” key (32) is pressed, the symbol mark M _{S of} FIG. 4A is first displayed on the symbol mark maker M _A, and when the user wants to change the symbol mark, by further pressing the “+” key (32), 4 It is sequentially changed from B to F in FIG. When the "-" key (33) is pressed, the change display is reversed. After setting the desired symbol mark M _S , use the cursor keys
Operate (35). In this way, the cursor "↓" is "month"
Since it moves to the front of, the above "+", "-" keys (32),
After selecting the month of the schedule to be set with (33) and setting the month, similarly use the shift key (35) to move the cursor "↓" to "day" and move the day with the same procedure. Is set.

Such a setting operation is also performed at the schedule setting time, and after setting the time, the cursor “↓” is moved to set the schedule title. The title display is in English or Roman letters. The selection of AZ is "+",
This is done with the "-" keys (32), (33).

For example, if a schedule (first schedule) starting from 10:00 am on September 21st is set (first schedule), the first set schedule SK ₁ is displayed on the upper left of the screen S as shown in FIG. 3D. Displayed in the section. The contents of these schedules are set while watching the TV screen S.

The contents of the second schedule SK ₂ are displayed on the right side of the _first schedule SK ₁ (upper right part of the screen S). In the embodiment, the schedule contents can be set up to n = 6th, and an example of the schedule arrangement is shown in FIG. 3D.

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

When the PPC key is operated after setting the schedule contents, this PPC key operation is often 4 seconds after the PPC key pressed immediately before, so at this time, the procedure returns to step a and the schedule display is replaced. Normal TV images are displayed.

In this example, in addition to the schedule display function, the contents of the phonebook can be input and displayed. If the PPC key is operated again 4 seconds before the schedule set mode is selected with the PPC key, , Go to step k and move to phonebook set mode.

In the phonebook set mode, as shown in FIG. 3E, the symbol mark MS of the phonebook is displayed on the upper left part of the screen S, the number of pages is displayed on the right side of the symbol mark M _S , and the remaining screen S is called. The book (name, number) is displayed. The telephone numbers for eight persons are displayed in tandem on one page, and in this example, the telephone numbers for four persons, that is, 32 persons, can be stored and displayed.

The cursor “↓” is located at the page number, and after specifying the page, the shift key (35) moves the cursor “↓” to the full name field, where the full name (full spelling) and initials of the first name are set in Roman letters. Then, in the number column, a number combined with "-(hyphen)" is set as shown in the figure. In this example, you can enter up to 14 Roman characters and up to 12 digits for a number.

The alphabets A to Z and the numbers 0 to 9 for names are all selected by "+", "-" keys- (32), (33).

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

Now, FIG. 1 is a flow chart showing an example of the display operation according to the present invention according to the 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 power is on, the process proceeds to step 41, and the counter is initialized to 1. This counter is for designating a plurality of types of schedules stored in advance. When the initial setting of the counter is completed, the process proceeds to step 42 and the date data set in the first set schedule (first (n = 1) schedule) is read out from the memory, and this data is stored in N Is made.

The data N is checked in step 43 for a match with the data indicating today's date, and when the respective data match, the process moves to step 44, and the first schedule is superimposed on a part of the television image. The position to be superimposed is, for example, in the lower right corner of the screen in this example, as shown in FIG. 3G. As shown in FIG. 3A, the superimposed image is the symbol mark M _S indicating the first schedule, the set date and time, and the schedule title M _T.

After superimposing, the process moves to step 45 and the destination counter is incremented by 1. If the data N and the data showing today's date do not match, step
Instead of 44, go to step 45. Therefore, in this case, the first schedule is not superimposed on the TV screen.

When the counter is incremented, the process proceeds to step 46, and it is checked whether n is 6 or more. If n is 6 or less, the process returns to step 42, and 2 corresponding to the counter value set in step 45 is set. The same operation as described above is repeated by checking the agreement between the date data of the second (n = 2) schedule and N.

Therefore, the maximum number of schedules that can be set (n =
6) Only the schedules are preset, and if the dates of the 3rd, 4th and 5th schedules among them are set to the same month and day, the 3rd, 4th and 5th schedules are set by the above control routine. Each of the schedules will be superimposed on the same screen. An example of the display position in this case is shown in FIG. 3G. In this way, the display position is determined so that the schedule to be superimposed moves from the lower right corner to the lower left corner of the screen.

If it is checked in step 46 that n has become 6 or more, the process moves to step 47, and the operation of the PPC key is checked. If the PPC key is operated, step 48
This deletes the schedule image and returns to the normal display mode in which only the television image is displayed on the screen. PP
If the C key is not operated, the schedule image continues to be displayed.

If step 50 is provided as shown in FIG. 1 and this step 50 is a step of determining whether or not, for example, 30 seconds have passed after the step 47, it is possible to operate the step 30 without operating the PPC key. The schedule image is automatically deleted after a lapse of seconds.

The determination time for automatic deletion is set to 30 seconds because it is considered to be sufficient time to read the schedule contents 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 the day is always superimposed on the television image on the schedule setting date.

Therefore, by turning on the power of the television, the preset today's schedule can be checked while looking at the screen, and there is no risk of missing the schedule.

In the above description, the schedule for the current day is superimposed on the date set in the schedule, but tomorrow's schedule is superimposed on the TV image on the day before the set date. It is also possible.

Also, since the schedule contents after the corresponding month and day have passed are no longer needed, there is a step of determining whether or not the corresponding month and day has passed, and when the time has passed, the schedule contents can be automatically deleted. Good.

〔The invention's effect〕

As described above, according to the present invention, if the schedule of a few days ago or a few months ago is stored beforehand, the schedule of the day can be accurately confirmed by watching the television on the date when the schedule is set. , It is very convenient in practice because it can surely prevent mistakes such as forgetting the schedule of the day.

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