Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a remote controller for electronic equipment such as a TV or a player, and generally relates to a remote controller called a learning remote controller.

[Conventional technology]

Conventionally, as a remote controller,
Infrared remote controllers used for TV sets are known. Here, if you select and press the control switch provided on the remote controller,
Infrared rays modulated by a signal (code) corresponding to the switch are output, and this is received by the TV set to decode the signal (code). For example, by operating the power ON/OFF switch and the channel switch of the control switches of the remote controller to turn on the power and set the channel to "1", the power to the TV set is turned on and channel "1" is received. In addition, in a TV system consisting of a monitor TV and an amplifier, infrared remote controllers are prepared for the monitor TV and for the amplifier, respectively.For example, when receiving channel "1", the power ON/OFF switch of the monitor TV remote controller is used. of
After turning ON and then turning ON the power ON/OFF switch of the amplifier remote controller,
Switch the function selector switch to AUX, and then switch the remote controller for the monitor TV.
After switching the TV selector to TV, operate the channel switch to "1".

[Problem to be solved by the invention]

In this way, remote TV viewing is only possible by performing switch control several times on the remote controller side, and even for channels that are frequently used, you may have to perform switch control many times for remote control each time. It was a hassle to have to operate it. Furthermore, in the case of a TV system that includes a TV monitor and an amplifier, separate remote controllers must be prepared and switches must be operated for each. The present invention has been made based on the above circumstances, and receives remote control signals from remote control transmitters corresponding to each of the system devices to be operated and stores them in a memory. This provides a remote controller that can send data all at once.

[Means to solve the problem]

For this purpose, there is provided a receiving section that receives remote control signals from a remote control transmitter corresponding to each of the system devices to be operated, a memory that stores the remote control signals received by this receiving section, and a memory that stores remote control signals received by this receiving section. writing means for writing the remote control signal into a memory; reading means for reading out the remote control signals written in the memory at once;
The present invention is characterized by comprising a transmitting section that sequentially transmits the remote control signals read by the reading means to the system equipment side.

【Example】

Hereinafter, one embodiment of the present invention will be specifically described with reference to the drawings. In the figure, reference numeral 1 is a receiving section that receives remote control signals (codes) by key operations, etc. The signals from the receiving section 1 are addressed by writing means 2, and are sequentially stored in a memory 3 whose power has been backed up. written. Further, there is a means 6 for reading out the contents of the memory 3, and a start switch 4 and a timer 5 are provided for outputting an external signal for activating the reading means 6. The remote control signal sent from the reading means 6 is received by the TV set via the transmitter 7 under remote control. Note that the transmitter 7 is equipped with, for example, a modulator, an oscillator, a light emitting diode, and the like. This receiving operation and transmitting operation are shown in Fig. 2 a and b.
This is shown in the flowchart. Regarding the receiving operation, as shown in FIG. 2a, first, the presence or absence of a remote control signal from the outside is detected, and if there is no remote control signal, the device waits for input of a signal. As a detection method, for example, there is a method in which the output of the receiving section 1 is set as a bit pattern of 0 and 1, and a microcomputer or the like calculates whether or not the output falls within a predetermined content range of a remote control signal. If there is a remote control signal, it checks whether there is space in the next memory 3. If there is no space, this process ends, and if there is space, the received content is stored in memory, the memory address is +1 and the initial state is returned. return. For example, if the memory capacity is 3 steps, when the remote controller switch is operated sequentially as "Power-ON", "TV", and "3ch", the remote control signal code will be $Co, $CF, and $C3. If there are, $Co, $CE, and $C3 are stored in memory 3. When a new remote control signal is set, the memory 3 is cleared. Regarding the transmission operation, as shown in FIG. 2b, the reading means 6 is started by the start switch 4 and the timer 5, and according to the above example, $Co,
$CF and $C3 are read out in order, and each time they are converted into a remote control signal and sent. In this way, by operating the start switch 4 once, multiple remote control signals stored in the memory 3 are read out and transmitted at once, achieving the same function as operating the switch on the remote controller three times. be able to. Furthermore, by setting an on time in the timer 5 in advance, the timer 5 outputs an external signal when the on time comes. The reading means 6 is activated. As a result, a plurality of remote control signals stored in the memory 3 are read out and transmitted in the same way as the above operation. In the above embodiment, the memory may be divided into a plurality of groups (units), and a remote control signal read out at once by a start switch, a timer, etc. may be written in each memory group. For example, a number of start switches 4 corresponding to the memory groups are prepared, and each start switch 4 is
are F1, F2, F3..., and for F1, "Power
-ON", "TV", "3ch", F2 can be "FM", "5ch", F3 can be "LD", "Chapter", "7", "Search", etc. Any number of steps can be stored as long as the memory contents are within the memory capacity of each memory unit. Note that means other than the above-mentioned start switch and timer may be used as the memory read activation signal. Furthermore, it may be possible to modify and edit the memory contents.

【Effect of the invention】

As described in detail above, the present invention stores in memory a series of remote control signals corresponding to each of the system devices to be operated by remote control, and reads and transmits them all at once as necessary. Since it is connected to a remote controller, you can avoid repeating troublesome operations each time you use remote control.
Improves operability. Further, since each remote control signal transmitted from a plurality of remote controllers can be transmitted at once by one remote controller, operability can be improved and remote control operations can be performed accurately. to
