Abstract

PURPOSE:To prevent both a timer reserve mode and a timer cancel mode from being effective by providing a reserve cancel switch, and switching the display of a reserved day of the week and time on an image receiving tube screen to a reserve cancel display when the switch is operated. CONSTITUTION:A control circuit 20 has a time timer and a program timer function for screen display, and its main body is a computer. Commands from this control circuit 20 are received to control a CRT control circuit 12 with an internal character generator and the microcomputer 11. The timer cancel key 27 for turning on and off a reserve timer is provided and when this key is off, a channel reserve display appears all the time. When the timer cancel key is on, the timer reserve display is switched to a blinking display unless a timer reservation is made. Thus, when the timer cancel key 27 is off, a normal channel reservation content display mode is entered, but when on, channel reservation contents are blinked.

Description

[Detailed Description of the Invention] Industrial Field of Application This invention relates to a television receiver that uses the picture tube surface of the television receiver to display the time and reservations for a timer program, particularly for a reservation cancellation function. The present invention relates to a television receiver having:

BACKGROUND TECHNOLOGY AND 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 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 more 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 In such cases, where there is no way to check which channels have been reserved and from what time to what time, it would be great if you could use the TV screen to display the content instead of the TV image, as you would be able to visually check the channel reservations. It is convenient and can definitely eliminate reservation mistakes.

By the way, in a television receiver having such a timer program function, when the timer reservation time arrives when you are currently watching a broadcast program, the reserved channel is suddenly switched to that reserved channel without any prior notice. People other than those who are noodlers cannot immediately judge whether or not channel switching is due to execution of a timer program, and may be confused for a moment.

In this case, if you superimpose and display the timer reservation details, such as the reserved day of the week, reservation time, and reserved channel, on the TV image immediately before the timer reservation time, you can at least confirm that the timer reservation time is near. Therefore, the above-mentioned drawbacks can be overcome.

Now, when you make a timer reservation, if you have to leave the house for urgent business at the timer reservation time, or if a special program is to be broadcast, you need to be able to temporarily cancel the execution of the timer reservation. be. However, even when adding a function to cancel timer reservations like this,
If this reservation cancellation status could be displayed on the CRT screen, it would be extremely convenient because it would reduce confusion between timer reservation mode and cancellation mode.

OBJECTS OF THE INVENTION Therefore, the present invention proposes a television receiver having a timer program function so that there is no confusion between timer reservation mode and cancellation mode.

SUMMARY OF THE INVENTION Therefore, in the present invention, a reservation cancellation switch is provided in a television receiver in which a timer program can be performed by displaying at least the reserved day and time on the screen of the picture tube. During operation, the display of the reservation day and time displayed on the picture tube surface is switched to a reservation cancellation display.

This prevents the user from confusing the timer reservation mode and the timer cancellation mode, and also makes it easy to confirm the timer cancellation.

The reservation cancellation display can be achieved by blinking display, changing the display color, etc.

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, and the images that should be superimposed on or in place of this television image are a channel reservation image and a clock image, but images other than these can also be used. It may also be possible to display it on the same CRT tube surface. In addition to these images, a television receiver to which this invention is applied can also display a monthly calendar and the like.

FIG. 1 shows an example of a television receiver according to the present invention, in which (1) 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, and (8) is a speaker.

(11) is a microcomputer for channel selection and volume control, which sends the tuning signal Ss to the tuner (1) and outputs the volume control signal SV to the output amplifier (7).
) is sent. (20) is a control circuit having clock timer and program timer functions for image display, and its main body is a microcomputer. In response to commands from this control circuit (20), a CRT control circuit (12) with a built-in character generator and a microcomputer (1)
1) is controlled. C'RT control circuit (12)
A red to blue character signal SC is generated.

The control circuit (20) includes a CPU (21) as is well known.
.

It has a ROM (22), a RAM (23), and an I10 port (24), and a remote control signal from a commander (described later) is input to the input port side of the I10 boat (24) via a light receiving element (25). The key inside the receiver (
26) to (28) are connected. The key (26) is a mode switching key provided on the receiver body, in this example P P
C (Programmable Wick Lip Cen
ter) key, and the key (27) is a timer cancellation key that can turn on and off the reservation timer.

The indicator light (28) is for indicating whether or not the timer is being executed, and is lit only when the timer cancel key (28) is off and the timer reservation is being executed.

The indicator light (28) can use a light emitting diode (LED), and a lighting command signal is supplied through the I10 port (24). Also, turn on the power switch of the receiver,
The relay drive circuit (15) to be turned off is connected to the I10 boat (24
) is controlled based on on/off command signals obtained from the (16) is a commercial AC source, and a manually controlled main power switch (17) is connected between the commercial AC source (16) and the relay drive circuit (15). When is off, timer reservations are not executed.

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 a channel direct selection key, the PCC key is a mode switching key with the same function as the one provided on the main unit, (32)
, (33) is r+J,'"-" key, (34) , (
35) are left and right shift keys. (36) is a pencil-shaped clock start key.

In this invention, time setting, channel reservation display, etc. are performed by a microcomputer. The time is "hour", "
You can set "year" and "month" in this example.
, ``day'' can also be set at the same time. An example of channel reservation display is shown in FIG. In this case, a channel reservation image is displayed instead of the television image. The channel reservation image is selected by operating the PPC key, and the background is blue and the characters and symbols are green.
The CRT control circuit (20) receives commands from the control circuit (20).
12), a character signal Sc is sent out.

Now, in channel reservation mode, rTIM[!] is displayed on the CRT screen as shown in Figure 3. The title RJ is displayed, and next to it is the current day of the week (Monday (MAN) ~
day (SUN)) and current time (hour.

(minutes, 2 seconds) is displayed. When the current time is not set, the day of the week and the current time are displayed with blinking.

Channel reservation (event reservation) is in the center of the CRT screen.
In this example, three events can be reserved. The reservation details range from 1 to ``what day of the week, what time, and 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, MF means every day from Monday to Friday, M-3 means every day from Monday to Saturday, and TDY means setting only for today. Also, "blank" means that the day of the week position is blank, and this is an option for prohibiting the execution of the sent 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, use the “+” key or 1-” key (32)
, (33). The ``+'' key selects the day of the week setting column by rotating in the direction of the arrow a, and the day of the week setting column is selected by rotating the ``1~'' key in the direction of the arrow. The cursor "↓" is moved using the left and right shift keys (34) and (35), and the "hour" setting is from 0 (hour) to 23 (hour), and the "minute" setting is 00 (minute) 00 ( seconds) to 59 (minutes) 00
(seconds).

Channel reservation is performed from the electronic label channel corresponding to channel display position 1 on the receiver body to the electronic label channel corresponding to position n in r+J, r-
This is done using the J keys (32) and (33). FIG. 3 is an example of a display when a timer reservation is made for "12 channels from 10 a.m. on Sunday."

FIG. 4 is a flowchart showing an example of the operation of the television receiver according to the present invention according to program data written in the ROM of the control circuit (20).

When the program starts, the program moves to the main processing routine in step 40, in which the remote control data, key manual data in the receiver body, power synchronization input for the clock timer formed using a commercial AC source, etc. are checked in I1.
0 baud) (24) within the CPU (21).
22), and also processes for realizing other display modes such as calendar display.

Next, in step 41, the timer reservation cancel key (
27) is checked to see if it is on or off, and if it is on, the timer reservation is canceled, so in this case, the timer operation flag is set in step 42, and if it is off, the timer reservation is executed. Therefore, in this case, a timer operation flag is set in step 43.

Then, in step 44, it is checked whether or not a channel reservation is being displayed.

In this example, one minute before the channel reservation time, the channel reservation details (in the example in Figure 3, SUN t:
oo 12CH) is superimposed, the presence or absence of this channel reservation display is checked in step 44. If the channel reservation display is not displayed, the process moves to step 4o, but if the channel reservation display is being displayed,
In step 45, the set state of the timer operation flag is checked.

When the timer operation flag is set, the timer reservation cancellation key (27) is turned off.
This means that the timer reservation is executed when the timer reservation time comes, so in this case, the channel reservation display is always displayed in step 46. On the other hand, when the timer operation flag is reset, the timer reservation will not be executed, so in this case, the timer reservation display is switched to a blinking display in step 47.

The timer reservation display starts from 1 minute before the timer reservation time and continues for a predetermined period (for example, 10 seconds) after the timer reservation time has elapsed.When this predetermined period of time has elapsed, the timer reservation contents are erased, and this is checked in step 44 and the main screen is displayed. Return to processing step 40.

In this way, when the timer reservation cancellation key (27) is off, it is the normal channel reservation content display mode, but
When it is on, the contents of the channel reservation are displayed blinking, so that cancellation of the timer reservation can be visually confirmed in advance.

Note that instead of displaying the channel reservation details in a blinking manner, cancellation of the °ζ timer reservation may be forewarned by changing the display color, or the channel reservation contents may be displayed in a blinking manner at the same time as the display color is changed. All of these can be easily achieved by simply changing some of the program contents.

DETAILED DESCRIPTION OF THE INVENTION As described in detail, the present invention provides a television receiver that displays at least the reserved day and time on the screen of the picture tube to perform a timer program. The display of the reservation day and time displayed on the screen is changed to a reservation cancellation display.

Therefore, in addition to the feature that the execution of a timer reservation can be temporarily canceled, the present invention also eliminates confusion between the timer reservation cancellation mode and the timer reservation mode, which is extremely convenient for practical use.
