Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a remote controller used for remote control of multiple controlled devices with different control signals. Regarding control transmitters.

0002

[Conventional technology]

Conventionally, video equipment such as television receivers and video cassette players, and stereo In many cases, audio equipment such as amplifiers and CD players have their own dedicated remote control. A control transmitter (hereinafter referred to as a remote control transmitter) is included. Each remote control transmitter has different frequencies, signal formats, etc. depending on the manufacturer and model. control signals to remotely control each controlled device.

0003 Therefore, multiple video equipment, audio equipment (target equipment) equipped with this type of remote control transmitter may When using a combination of control devices), you may have to operate multiple remote control transmitters. This makes the operation complicated and inconvenient. For example, a paid satellite broadcasting receiving device uses a decoder as a satellite broadcasting receiving device (BS channel). satellite) and a television receiver. Although it may be used alone when receiving other than broadcast reception, it is also used as a decoder and BS tuner. can be used simultaneously only when receiving satellite broadcasts.

0004 Then, connect the receiver, decoder, and BS tuner to their respective attached remote control transmitters. When controlling with It's a hassle. Therefore, a remote control transmitter called a compatible remote control or multi-remote control has been devised.

[0005] This transmitter is disclosed in, for example, Japanese Unexamined Patent Publication No. 146291/1983 (H04Q 9/00 ), by operating the switch for switching the transmission signal, Selectively switches to the attached remote control transmitter of multiple controlled devices, and each controlled device's Shared for control. In other words, the conventional infrared type controller is used for remote control of two controlled devices. The portable remote control is configured as shown in FIG.

[0006] In the figure, 1 is a transmission control unit with an IC configuration, and 2 is a matrix of a plurality of operation keys 3. 4 is a switch for switching the transmission signal, 5 is a transmission signal A transistor for control, 6 a light emitting diode for transmission output, 7 a transistor 5 The emitter resistor 8 is a power supply terminal.

[0007] Then, the transmission control unit 1 forms a control signal according to the control content of each operation key 3, The transistor 5 is driven by this signal to control the light emission of the diode 6, and the control signal is converts the signal into infrared light and transmits it. At this time, the control signals of both controlled devices may be signals with different custom codes, for example. If so, the transmission control unit 1 generates a custom code by turning on and off the switch 4. is selectively switched to a custom code for both controlled devices.

[0008]

[Problem that the idea aims to solve]

In the case of the conventional remote control transmitter, it is necessary to switch switch 4 for each controlled device. In particular, when the decoder and BS tuner are turned on, etc. Even for the same control of multiple controlled devices, switch 4 can be changed for each controlled device. The problem is that the same operation has to be repeated over and over again, resulting in poor operability.

[0009] This invention is particularly useful for controlling the same control of multiple controlled devices with different control signals that are used simultaneously. To enable control without the conventional switching of switches and repetition of operations.

0010

[Means to solve the problem]

In order to achieve the above object, the remote control transmitter of the present invention uses a control signal. An operation panel with shared operation keys used for simultaneous control of multiple controlled devices with different monitors the key operations on the panel section and the panel section, and when the shared operation key is operated, Transmission that sequentially forms multiple types of control signals with control contents and outputs them as transmission signals. It includes a control section and a transmission output section that transmits and outputs the transmission signal.

[0011]

[Effect]

In the case of the remote control transmitter of the present invention configured as described above, the satellite broadcast receiving device When applied to the control of A shared operation key is provided as an operation key for the player.

0012 Then, when the shared operation key is operated, the transmission control unit controls the power on, etc. A sequential signal of multiple types of control signals according to the transmission signal is output as a transmission signal. signal is transmitted from the transmission output.

[0013] At this time, since the transmitted signal includes control signals for the decoder and BS tuner, The decoder and BS tuner are powered on simultaneously by the signal. Therefore, it eliminates the conventional switch switching and repeated operations for each controlled device. The coder and BS tuner can be controlled.

[0014]

【Example】

One embodiment will be described with reference to FIGS. 1 to 4. In this embodiment, a television receiver and a satellite broadcast receiving device are constructed. It is applied to control the BS tuner, decoder, and BS tuner, and is used simultaneously when receiving satellite broadcasts. The operation keys of the decoder and BS tuner are shared.

[0015] Therefore, as shown in FIG. 2, the remote control transmitter 9 is installed on the front operation panel section 10. A common device equipped with multiple common operation keys 11 used to control the decoder and BS tuner. The receiver is equipped with an operation section 12 for controlling the receiver, and a plurality of individual operation keys 13 used for controlling the receiver. An image machine operation section 14 is provided.

[0016] Furthermore, the remote control transmitter 9 has a circuit configuration as shown in FIG. 15 is a transmission control section configured with a microcomputer, and a decoding processing control section 16 , an oscillation circuit 17, a shared signal generation section 18, and an individual signal generation section 19. 20 is The drive circuit 2 is a transmission output section, and is formed by the transistor 5 and the resistor 7 in FIG. 5, for example. 1 and a light emitting section 22 formed by a diode 6. Note that each common operation key 11 and each individual operation key 13 are different from each operation key 3 in FIG. They are also arranged in a matrix.

[0017] The processing control unit 16 operates using the output signal of the oscillation circuit 17 as a reference signal, The transmission process shown in FIG. 3 is executed by monitoring key operations on the operation panel unit 10. In other words, when either of the operation keys 11 or 13 is pressed, processing is performed according to that key signal. The control unit 16 detects a "key input" and at the same time decodes the key signal to detect the pressed key. Determine the control content corresponding to the selected key.

[0018] The decoder and BS chip whose control content is based on one of the shared operation keys 11 When turning on the power of the tuner, the processing control section 16 sends the shared signal generation section 18 to the decoder. , Output of control signals of Company A, Company B, and Company C used as control signals of BS tuner are given in order at predetermined intervals (cycles). Based on this command, the shared signal generating unit 18 is pressed as shown in FIG. 4(b). Each company's control signals A, B, and C corresponding to the control content of the key are formed in order, and the control signal A is , A, and C are sequentially output to the transmission output section 20 as transmission signals.

[0019] Furthermore, the transmission output section 20 converts the transmission signal into infrared light, and this infrared light is emitted. It is transmitted from the photodiode 22. Then, the decoder and BS tuner are controlled by control signals from companies A and B, for example. When receiving the control signals of Company A and Company B included in the infrared light transmission signal, This means that turning on the power to the decoder and BS tuner does not require the conventional switch switching and key operations. The work is done simultaneously, eliminating repetition.

[0020] By the way, the shared signal generation unit 18 generates the control signals of each company only once and transmits them as transmission signals. shall be. This means that each company's control signal is repeated multiple times, especially in the case of toggle control such as power-on. When you send it back, the power of the decoder and BS tuner will turn on and off alternately. This is because a situation may occur where erroneous control occurs.

[0021] Note that if the operation key 12 is kept pressed, the key on period T shown in FIG. When continuing even after the transmission signal is output, the period T is determined by key determination after the transmission signal is output. Repeated transmission of the transmission signal after the end of the period is prohibited.

[0022] On the other hand, the determined control content is based on one of the individual operation keys 13. In the case of power on, etc., the processing control section 16 sends the control signal of the receiver to the individual signal generation section 19. Command output. Based on this command, the individual signal generation unit 19 responds to the control content of the pressed key. Forms a control signal for the receiver and outputs this signal to the transmission output section 20 as a transmission signal. Ru.

[0023] Therefore, when each individual operation key 13 is pressed, the receiver is turned on, etc. , again the conventional switching is omitted. Also, while each individual operation key 13 is pressed, the A corresponding control signal is sent repeatedly.

[0024] In the case of the above embodiment, not only the decoder and BS tuner but also the receiver can be controlled with one remote control transmitter, and three controlled devices can be controlled using a conventional switch. It has the advantage of being controllable without switching. Of course, it can also be applied to control multiple controlled devices of various types that are used simultaneously. It is.

[0025]

[Effect of the idea] Since the present invention is configured as explained above, it achieves the effects described below. do. A shared operation key 11 is provided on the operation panel section 9, and transmission control is performed when this key 11 is operated. The unit 15 sequentially transmits a plurality of types of control signals corresponding to the control contents of the operated key. Since this transmission signal was output from the transmission output section 20, the common Conventional switch switching for each controlled device can be done by just one operation of the operating key 11. It is also possible to turn on the power of multiple controlled devices at the same time without having to repeat operations. This can significantly improve operability.
