Abstract

PURPOSE:To prolong the life of a battery to be used to a remote device and to cause the battery to be compact by providing the remote device to optically output a simplified single signal and a converting unit to convert the photo- detected single signal to a composite signal when the single signal is decoded and controlling a television receiver and a VCR device, etc., with the composite signal from the converting unit. CONSTITUTION:When a key switch 7a is operated and a single signal A to correspond to the key switch is emitted to a photo-detecting device 6a of a converting unit 6, the single signal is converted to the electric signal of digital and inputted to a CPU6c of the converting unit 6. The CPU6c decodes a pattern to correspond to the signal A out of the plural patterns, which are stored to a memory 6b. The data are caused to be the composite signal to control the power source of a television receiver 1 and surround AMP4 to be turned on through a data output device 6d and outputted to the respective devices of the AV system. Accordingly, a remote device 7 is completed with extremely simple constitution and since the optical single signal is emitted only in one direction of the converting unit 6, the signal can be transmitted without fail.

Description

[Detailed Description of the Invention] [Industrial Application Fields] This invention is applicable to television receivers, VC
It relates to a remote control method that controls R devices, VD/CD devices, etc. using composite signals.More specifically, a single signal is output from the remote device, and based on this single signal, the TV receiver, VCR device, VD/CD device, etc. AV that controls CD devices, etc.
This relates to a system remote control method.

[Conventional Example] In recent years, various AV systems have been proposed in response to the individuality of users. This AV system includes, for example, a television receiver 1, a VCR device 2, and a VCR device 2, as shown in FIG.
It is composed of a D/CD (video disc/compact disc) device 3, a surround AMP 4, etc., and is controlled by a remote signal emitted from a remote device 5.

This remote device 5 emits a composite signal for controlling a plurality of devices using light such as infrared rays.

In order to receive the signal, those television receivers1. The VCR device 2, VD/CD device 3, surround AMP 4, etc. are equipped with a light receiving section. A feature of this remote control method is that the signals emitted from the remote device 5 are composite. In other words, signals can be sent to each device making up the AV system with a single touch operation. Therefore, there is no need to operate the remote device 5 for each device, and there is no need to provide the remote device 5 for each device.

[Problems to be Solved by the Invention] However, the remote device 5 uses a CPU (one-chip microcomputer) for controlling the output of the composite signal. The origin, remote device 5
Not only does this shorten the life of the battery, but it is also difficult to make it more compact. Furthermore, not all the devices making up the above AV system are arranged in one direction.

For example, they may be placed in different directions. In such a case, even if a remote signal is emitted from the remote device 5, a situation may occur where the signal is received by one device but not by another device. In other words, it is not possible to control a plurality of devices synchronously, and therefore, even if the remote device 5 is operated several times, the devices sometimes keep jerking around and cannot be controlled.

This invention was made in view of the above-mentioned problems, and its purpose is to provide an AV system that can extend the life of batteries used in remote devices, can be made more compact, and can control the AV system reliably. The purpose of this invention is to provide a remote control method for

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a television receiver,
In an AV system comprising a VCR device, a VD/CD device, etc., the television receiver, the VCR device, the VD/CD device, etc. are controlled by remote control.
A remote device that corresponds to a signal for controlling an R device, a VD/CD device, etc. and outputs a simplified single signal as an optical signal; a remote device that receives the single signal, decodes the received single signal, and , converting the decoded signal into a composite signal, and transmitting the composite signal to the television receiver or VCR device.

and a conversion unit that outputs to a VD/CD device etc., and the composite signal from the conversion unit is used to convert the TV receiver to the VD/CD device.
It is designed to control CR*, VD7CD devices, etc.

[Example] Hereinafter, an example of the present invention will be described based on the drawings. In addition, in the figure, the same parts as in FIG. 3 are given the same reference numerals, and redundant explanation will be omitted.

In the figure, the conversion unit 6 includes a remote device! ! A light receiving device 6a receives a single signal using light such as infrared rays emitted from 7, converts it into a digital electrical signal and outputs it, and one of a plurality of patterns in which the single signal is stored in advance in a memory 6b. A CPU (one-chip microcomputer) 6c selects, deciphers, and obtains data for controlling each device of the AV system from the memory 6b based on the pattern, and outputs this data as a control signal for each device. An output device 6d and the like are provided.

The signal from this output device 6d is input to each device, such as the television receiver 1, VCR device 2, VD/CD device 3, surround AMP 4, etc., via wires. Note that this signal may be light, and in this case, it may be converted into an optical signal near the light receiving section provided in each device.

On the other hand, the remote device 7 is provided with a number of key switches 7a corresponding to the decoding patterns stored in the memory 6b, for example. This single key switch sets the states of multiple devices within the AV system. That is, the remote device 7 has a simple configuration of a key switch 7a and a circuit that generates a single signal.

Next, the operations of the remote device and conversion unit of the AV system will be explained based on the flowchart of FIG. 2.

First, in step 5T, the conversion unit 6 executes the initial settings necessary to set the status of each device of the AV system.
I) Wait until a single signal (remote control signal) such as infrared rays emitted from the remote device 7 is input to the light receiving device 6a (step 5T2).

Here, in order to turn on the power of the television receiver 1 and surround AMP 4 of the AV system, the key switch 7a is operated, and a single signal A corresponding to the key switch is emitted toward the light receiving device 6a of the conversion unit 6. Then, the single signal is converted into a digital electrical signal and input to the CPU 6c of the conversion unit 6. Then, CPU6c
is the pattern x+y corresponding to the signal A among the plurality of patterns stored in the memory 6b (x: Turn on the power of the television receiver 1, Y: Turn on the power of the surround AMP 4.
(equivalent to ), and further based on the pattern, data X for turning on the television receiver 1 is read out from the memory 6b, and data Y for turning on the power for the surround AMP 4 is read out and set respectively. (step 5T3), that is, the single signal A
is decoded into an X+Y signal, and the signal x+Y is converted into data (composite signal) for controlling each device.

Next, the data is converted into a composite signal that turns on the power of the television receiver 1 and the surround AMP 4 via the output device E6d, and is output to each device of the AV system (step 5T5). The receiver 1 and the surround AMP 4 perform an operation of turning on their respective power supplies.

In this way, an optical signal in the form of an extremely simple code is emitted from the remote device 7, and the code signal is decoded by the conversion unit 6 and converted into setting data for the status of each device in the AV system. , a composite signal, and output to each device. Therefore, the remote device 7 only needs to have an extremely simple configuration, and it only needs to emit a single optical signal in one direction of the conversion unit 6, so the signal is reliably transmitted and each device of the AV system can be reliably controlled. can do.

In the above embodiment, the case where the power of the television receiver 1 and the surround AMP 4 are turned on has been described, but the same operations as the conventional remote control method, such as channel switching of the television receiver 1 and recording of the VCR device 2, are described. can be done similarly.

[Effects of the Invention] As explained above, according to the present invention, a remote device that outputs a single signal corresponding to the status setting of a television receiver, an NCR device, a VD/CD device, etc. of an AV system, and inputting the signal, converting the single signal into the composite signal, and transmitting the composite signal to the television receiver.

Since it is equipped with a conversion unit that outputs to an imager, VCR device, VD/CD device, etc., the configuration of the remote device can be made extremely simple, and the life of the battery used in the remote device can be extended. This has the effect of making it more compact and easier to use. Furthermore, it is only necessary to direct a single signal from the remote device in the direction of the conversion unit, and the signal can be transmitted reliably.
