Abstract

PURPOSE:To eliminate the trouble of restoring a channel after the end of reservation during viewing by depressing a reservation switch and inhibiting an output of a remote control transmission quantity at the same time in using the commander for the reservation. CONSTITUTION:In order to eliminate the trouble of restoring a channel during viewing, when a reservation switch 3 is turned on, the signal is fed to a switching circuit 24 at the same time and a signal from remote control switch groups 8-15 is fed to a channel memory 22 and not fed to a remote control transmitter 25 by selective operation. That is, a switch 24' controlled by a reservation switch 3 provided to the circuit so far is replaced into a switching circuit 24 operated selectively and a signal from the switch section 8-15 at the OFF state of the reservation switch 3 is fed only to the remote control transmitter 25 and not fed to a memory 22, and in case of the ON-state, the signal from the switch groups 8-15 is fed only to the memory 22 and not fed to the transmitter 25.

) is a switch that specifies the number of minutes. Reservation switch (
You can set the current time by turning 3) off and operating the time set switch (4), and by turning on the reservation switch (3) and operating the time set switch (4).
By operating , you can set or change the reservation time.

(5)! ′! The output mode changeover switch is used to change the content to be performed when the reserved time is reached.

The switching contents include AL mode, which generates an alarm sound, and TV mode, which turns on the TL source of the television receiver and selects a pre-specified channel. I have a neck. (6
) is the alarm stop switch, which stops the alarm when pressed while the alarm is occurring. (8) is a channel switch, which has 12 buttons corresponding to channels 1 to 12. When any channel button is pressed, the channel corresponding to the pressed button is designated. (9) is a power switch which, when pressed, turns the television receiver's power on and off. (1o) is a channel up switch, which increments the channel number currently being received by one each time it is pressed.

(11) is a channel down switch, which decreases the channel number currently being received by one each time it is pressed. (
12) is a volume up switch that increases the opening volume at a constant speed. (13) is a volume down switch, which reduces the opening volume at a constant speed. (14) is a sleeping switch, (15
) is a minting switch.

FIG. 4 is a block diagram showing essential parts of the commander of FIG. 3. In the same figure, (1) to (15) are the same as explained with respect to FIG. (16) is a decoder,
Time data from the reservation time storage unit (17) and clock (18)
), the time data designated by the display mode changeover switch (2) is decoded, and the time is displayed on the display section (1). Note that once the time is stored in the reservation time storage section (17), the time will not change unless changed by operating the time set switch (4), so if the reservation time is the same as the time of the previous timer reservation, the operation to set the time is not necessary. does not require. therefore,
You can continue to make timer reservations for the same time every day without any special reservation operations. (19) is a comparison circuit that compares the time stored in the reserved time storage section (17) and the time of the clock (18), and when the two match, sends a match signal to the output mode switching circuit (20).

When the output mode switching circuit (20) receives a match signal from the comparison circuit (19), the output mode switching circuit (20) outputs the output to the one specified by the output mode switching switch (5) between the alarm generation circuit (21) and the channel memory (22). Send a signal. The alarm generation circuit (21) is connected to the output mode switching circuit (20
), it sends out an audio signal that generates a warning sound to the speaker (23). If the alarm stop switch (6) is pressed while an alarm is occurring, the alarm is stopped. The channel memory (22) is a memory in which the reserved channel is stored by turning on the reservation switch (3), setting the reservation time, and then pressing the channel button.
(24') is a switch, remote control switch group (8) ~
It functions to send the signal from (15) to the channel memory (22) when the reservation switch (3) is turned on. The remote control transmitter (25) includes remote control switch groups (8) to (15)
Or when receiving a signal from the channel memory (22),
In response, a remote control signal is sent to the light emitting diode (26). Then, the diode 2
6) converts the remote control signal into a signal using infrared light.

Next, the operating method and operation of the commanders shown in FIGS. 3 and 14 will be explained.

If you want to remotely control the current status of the television receiver, turn off the reservation switch (3) and
When an appropriate one of the remote control switch groups (8) to (15) is operated, signals corresponding to the operation are sent directly to the remote control transmitter (25), and those signals are further transmitted to the red light by the light emitting diode (26). The light is converted into external light and transmitted to a receiving section of a television receiver (not shown).

To make a timer reservation when the television receiver is not receiving signals, press the reservation switch [3], set the reservation time using the time set switch (4), and press the button corresponding to the desired channel among the channel switches (8). When you press
A signal specifying the channel is sent to the channel memory (22) via the switch (24') and stored therein.

Further, the output mode changeover switch (5) is switched to TV mode. Check the reservation time mode displayed on the display section (1) to confirm that the reservation has been completed, and then turn off the reservation switch (3). Then, when the reserved time set in the reserved time storage section (17) is reached, the output mode switching circuit (2
0) to the channel memo IJ (22), and the stored contents of the channel memory (22) are read out by the remote control transmitter (25). Remote control transmitter (25
) first sends out a signal to turn on the television receiver, and then sends out a reserved channel signal read from the channel memory (22). As a result, the television receiver selects the reserved channel and enters the receiving state. Note that if the N7Tfi switch (9) is turned off, the television receiver will not enter the receiving state during the reservation operation.

[Problem to be solved by the invention]

Even when the television receiver is in reception mode,
There are times when I want to set a timer so I don't forget. In that case, first turn on the reservation switch (3), set the reservation time with the time set switch (4), set the output mode selector switch (5) to TV mode, and press the desired channel button of the channel switches (8). Pressing is the same as before, but if you input, for example, channel 6 as the desired channel using the channel switch (8), the infrared output corresponding to the 6th channel will be output, and at that time the television receiver will switch to the 6th channel. If you are watching any other program, it will change to channel 6.

Therefore, after the reservation operation is completed, the user must perform an operation to restore the channel to its original state, which is very troublesome.

[Means for solving the problem: In order to eliminate the above-mentioned troubles, the present invention prohibits the output of the remote control transmitter (25), that is, the remote control signal 1, only when the timer is set.

[Effect]

Referring to the embodiment shown in FIG. 1, when the reservation switch (3) is turned on, the signal is simultaneously transmitted to the switching circuit (24).
), and the switching circuit VT (24) sends the signals from the remote control switch group (8) to (X5) to the channel memo J (22>), but so as not to send them to the remote control transmitter (25). perform selective actions.

〔Example〕

FIG. 1 is a block diagram showing one embodiment of the present invention.

In this figure, parts corresponding to those in FIG. 4 are given the same reference numerals. The configuration shown in FIG. 1 is different from the configuration shown in FIG. 4 in that the switch (24') controlled by the reservation switch (3) is replaced with a switching circuit (24) that performs a selection operation. That is, the switch (24') in FIG.
The switch simply opened and closed the signal path from the remote control switch group (8) to (15) to the channel memo 17 (22), but the switching circuit (24> in Figure 1) When turned off, remote control switch group (8) ~
The signal from (15) is supplied only to the remote control transmitter (25), not to the channel memo IJ (22), and is activated when the reservation switch (3) is turned on.
It operates so that the signal from (15) is supplied only to the channel memo IJ (22) and not to the remote control transmitter (25). Such a switching circuit can be easily designed by those skilled in the art, so a detailed description thereof will be omitted.

It is also possible to configure the main part of the above-described embodiment with a microcomputer, and in that case, the flowchart of the timer reservation execution program executed by the microcomputer is as shown in FIG. In this case, the planar shape of the commander, the position of the switches, etc. do not change. To explain the operation, first, in step (a), it is determined whether or not the reservation switch (3) is on. If the judgment result is no, repeat step (a); if the judgment result is yes, repeat step (a).
Proceed to (b) and prohibit the output of the remote control transmitter (25). In step (c), it is determined whether the reserved time has been set, that is, whether the time set switch (4) has been operated. If no, repeat step (c); if yes, proceed to step (d) to memorize the reservation time. In step (E), it is checked whether the output mode selector switch (5) is switched to TV mode. If no, go back to step (a), and if yes, go to step (go). In step (to), it is checked whether one button of the channel switches (8) has been pressed. If no, repeat step (to); if yes, repeat step (to)
The channel corresponding to the pressed button is memorized. When step (G) is completed, return to step (B).

〔Effect of the invention〕

As explained above, according to the present invention, when making a reservation using a commander with a timer, the output of the remote control transmitter is prohibited at the same time as the reservation switch is pressed, so that the channel on the television receiver being viewed is not reserved. This has the advantage of eliminating the hassle of switching channels and switching back to the original channel after completing the reservation operation.
