CONSTITUTION:When dates, times, and channels are displayed on a receiving tube to reserve a timer program, plural set rows of days of the week are set preliminarily, and one set row of days of the week is selected from them to set a date. The blank position is provided in this set row of days of the week, execution of reservation is inhibited if this blank position is selected at the data setting time. If another day of the week is set again after the blank position is selected once, the inhibition of reservation execution is released; and thus, the release of the inhibition is operated easily.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a television receiver that can display the time and timer program reservations using the picture tube surface of the television receiver, and in particular to a day-of-the-week setting column. The present invention relates to a television receiver in which a blank position is provided, and execution of a reservation can be prohibited when the blank position is selected.

Background technology and its problems In current television receivers, the current time signal is sent from the station only during a specific time period, so it is displayed only during a specific time period, and is not displayed at other times. , it is impossible to check the current time on the TV screen. However, when watching a broadcast program, it would be convenient if the current time etc. could be selectively displayed and superimposed on the television screen. At this time, it would be very convenient if today's date, day of the week, etc. could be displayed at the same time.

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 due to missed broadcast times or forgetting 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.

In this case, when prohibiting the execution of the reserved program contents, if the execution can only be prohibited by erasing all the set program contents, the operation for prohibiting the execution becomes troublesome.

Purpose of the Invention Therefore, in this invention, time and channel reservations can be
With a television receiver that can be used using the screen,
The operability is improved by making it possible to extremely easily perform an operation for prohibiting the execution of a reserved channel.

SUMMARY OF THE INVENTION Therefore, in this invention, the date for channel reservation is set by selecting from a plurality of preset day of the week setting columns, and a blank position is provided in the day of the week setting column, and this blank position is selected. In this case, execution of the reservation is prohibited.

In this way, reservation execution can be prohibited simply by selecting the blank position, so setting the prohibition mode is extremely simple and operability is further improved.

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

In this invention, the basic image is a television image! The images that should be superimposed on or in place of this TV image are channel reservation images and clock images, but it is also possible to display images other than these on the same CRT screen. good. In addition to these images, the television receiver to which the present invention is applied can also display a monthly calendar and the like.

FIG. 3 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 a channel direct selection key, the FCC key is a mode switching key with the same function as the one provided on the main body, (32)
, (33) is l+''.

The rJ keys, (34) and (35) are left and right shift keys. (36) is a pencil-shaped clock start key.

In the present invention, a microcomputer performs time setting, calendar display, etc. Figure 4 is a display flowchart that explains the above-mentioned image display in relation to key operations.Using this to explain the outline of the operation procedure, first, when the main power is turned on, a normal TV image (hereinafter such various (The displayed image is called a page) (Step a) is displayed, and if you press the PPC key here, if the current time is in cents, a predetermined year and month will be displayed on the TV image, regardless of the actual year, month, and day. The date and time are superimposed (step b). The date and time at this time are displayed in blinking mode. This is to visually notify the user that the time etc. have not been set yet. An example of the date and time display is shown in FIG. 5A. Also, during this display, a cursor "1-↓" which is a data setting mark is displayed.

Here, as shown in Figure 5A, the display of the year, month, day, etc. is as follows: January 1, 2001 0':OO When the month and day are displayed from 1 to 9, The 10th place of "month" and "1st day" is blank. That is, for example, 2001 1*Month 1*Day 0:00 is not displayed in the blank position (tens place) as shown above.

Cent the year, month, day and time while moving the cursor. The display after cents will be, for example, May 22, 1984 0:00.

When the current time is set and the clock is already running, the actual date and time are superimposed and displayed (step C). In this case, as shown in Figure 5B, the "month" and "day" are not displayed, and the date of this month, for example, May 22nd, is displayed with the month and date as shown in I-5/22J. The spaces are connected by slashes. At this time, if the month or day digit is a single digit, it should not be 1-5*/22J. The purpose of displaying in this manner as 1-/ is to prevent the television image from becoming invisible due to the information to be imposed. Then, the microcomputer of the control circuit (20) calculates today's day of the week from the set year, month, and day, and displays it between the month, day, and time.

After a certain period of time, for example 10 seconds, has elapsed since switching to month/day and time display, only the time is displayed (step i). This is because once the user recognizes the month and date, it is no longer necessary to constantly display the month and date.

If you operate the PPC key while the time is displayed, the time display will disappear.

Furthermore, if the PPC key is operated before 10 seconds have passed after switching to month/day/time display, the display state will switch to the next page.

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. , the display mode is switched to the one shown in FIG. 5B. Instead of operating the clock start key (36), if you press the PPC key, the data setting mark [↓J cursor displayed at the 1 year] position will change to +
If the clock is not in the 100 J range, press the clock start key (
Similar to the operation in step 36), the clock start mode is entered, and this month's calendar is displayed instead of the television image (step f). If you press the PP and C keys from step C, this month's calendar will be displayed in the same way. This calendar displays today's calendar date differently from the others.

Press the PPC key after Stella Acupoint, the page will change to channel reservation mode (step g), and CR
A channel reservation image is displayed on the T-tube screen in place of the television image. An example of a reserved image is shown in Figure 5C. The H'f details of channel reservation will be described later.

If you press the rf&PPC key during channel reservation or end of channel reservation, a normal TV image will be displayed.

Also, if you press the PPC key in step b or the rpc key in step d with the cursor at the r100J position, a demonstration calendar will be displayed (step h).
. An example of the demonstration calendar is shown in Figure 5. In this way, the year and month displayed in step b are displayed on the demonstration calendar. And this demo calendar will run for a few seconds (2
~3 seconds) and the calendar for the next month is displayed in sequence. In this case, all dates on the calendar disappear once, and the next moment a scroll-down display is performed in which the days are displayed sequentially from the 1st. The calendar follows the Gregorian calendar and is displayed from January 0000 to December 9999.

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.

In addition, from the CRT control circuit (25) shown in FIG.
A blue character signal 5R-s is output, and in the case of a calendar display, the background is entirely blue, Sunday rsUJO table and dates related to this day are red, and other days of the week (MO (Monday) to SA (Saturday) ” and the shoulders are controlled based on command data from the control circuit (20) so that the color is green.

In case of channel reservation display, the background is blue and text,
The symbol is green.

Now, in the channel reservation mode, as shown in Figure 5C, the title "I'TIMERJ" is displayed on the CRT screen, and next to it is the current day of the week (Monday (MA)).
N) ~ day (SUN)) and current time (hour.

minutes and 7 seconds) is displayed. When the current time is not set, the day of the week and the current time are displayed with blinking.

CRT Management Menkabu Channel Reservation (Event Reservation)
In this example, three events can be reserved. The reservation details range from "what day of the week and what time to what channel."

The display of "ON" is the on time.

The day of the week is selected from a plurality of preset examples of day of the week settings. An example of a day of the week setting column is shown below.

In this day of the week setting column, M to F are for every day from Monday to Friday, M-3 is for every day from Monday to Saturday, and TDY is for today only. Also, "blank" means that the day of the week position is blank, and this is an option for prohibiting execution of the set reserved channel. In this case, if the blank setting is changed, reservation data other than days of the week will be treated as valid.

To select the day of the week setting column, press the 1+” key or 1-” key (32)
, , (33). 1+” key is arrow a
The day of the week setting column is selected by rotating the 1-" key, and the day of the week setting column is selected by rotating the 1-" key in the direction of the arrow. The cursor "↓" is controlled by the left and right shift keys (34) and (35),
The cent of "E o'clock" is from O (hour) to 23 (hour),
cents for "r minutes" are from 00 (minutes) 00 (seconds) to 59 (minutes)
00 (seconds).

Channel reservation is performed from the electronic Rahel channel corresponding to channel display position 1 on the receiver body to the electronic Rahel channel corresponding to position n by r+J, r.
- Use the J keys (32) and (33). FIG. 5C is an example of a display when a timer reservation is made for [12 channels from 10:00 a.m. on Sunday].

A confirmation sound is emitted when the first event reservation is completed and the next event reservation is to be made. At this time, the audio control signal S is sent out from the control circuit (20). Event reservation order is arbitrary.

FIG. 6 is a four-part flowchart illustrating an example of the display operation according to the program data written in the ROM of the control circuit (20).

When the program starts, the program moves to the main processing routine of step 40, and the power source 1 is processed such as remote control data, key human power data inside the receiver, and power synchronization input for the clock timer formed using a commercial AC source.
The ROM (
22), and also processes for realizing other display modes such as calendar display.

Next, in step 41, the I-+J, l-J keys are pressed.
The presence or absence of remote control human power is determined based on the operations in (32) and (33), and if there is no remote control input, step 4 is performed.
In step 2, other remote control processing is performed, and if there is a remote control input, the process moves to step 43.

In step 43, it is checked whether the page displayed on the CRT screen is a channel reservation page, and if it is not a channel reservation page, the process moves to step 44, where other pages are processed.

When the channel reservation page is displayed, the position of ``cursor 1↓'' is checked in step 45, and the cursor 1
When "↓" is at the day of the week position, check which event reservation position the cursor 1 - "↓" is located at (step 4).
6) Next, in step 47, day of the week changing processing is executed.

After setting the day of the week, if you move the cursor "↓" to a setting position other than the day of the week, this will be checked again at step 45, and if this is the case, the program will move to step 48 and set the cursor "1 o'clock" and "1 minute" according to the position of the cursor "↓". "and 1-channel" reservation is executed, and the contents of this reservation are displayed in step 49.

In addition, in the case of setting the day of the week, it is determined in step 51 whether the set day of the week is blank or not, and if it is not set blank, the process moves to step 52 and the reservation data of the reserved event is displayed on the CRT screen. If the setting is blank, the process moves to step 53, and if there is already reserved data, the reserved data (hour 1 minute, channel reservation data) is not displayed. This confirms that you are in the "Prohibit mode".

In the channel reservation mode, it is checked in step 54 whether or not the channel reservation whose timer on time has come has been set to blank. If not, the process moves to step 55 and the current reservation operation is executed. That is, when the television receiver is off, the power is turned on and the reserved channel is selected, and when the receiver is on, today's date, day of the week, and current time are displayed (superimposed). At the same time, the channel is automatically switched to the reserved channel with a confirmation sound.

If the setting is blank, the reservation is not executed and the process returns to main processing step 40.

As described in detail, in this invention, the date and time for channel reservation can be selected by selecting from a plurality of preset day of the week setting columns, so that the reservation operation is extremely simple. In addition, a blank position is provided in the day of the week setting column, and when this blank position is selected, the execution of the reservation is prohibited, so that the execution of the reservation can be prohibited simply by selecting the blank position. Therefore, the prohibition mode can be set extremely easily, and the operability is further improved.

Then, by simply selecting another day of the week from the day of the week setting column from the blank day of the week, you can restore the reservation details, making it extremely easy to cancel the reservation prohibition mode, which is extremely convenient for practical use. It is.
