2. Description of the Related Art Normally, in remote control of a television receiver or the like which uses infrared rays as a transmission medium, a remote control code is different for each manufacturer and for each device from the viewpoint of preventing malfunction between the devices.

[0003]

Therefore, when operating a plurality of devices by remote control, a remote control signal transmitter dedicated to each device (hereinafter referred to as "remote control") must be used. By the way, in a television receiver to which various video devices are connected, it may be convenient for the television receiver to operate in conjunction with it depending on the operation content of the connected device. For example, when the VTR is connected, it is convenient if the power of the television receiver is turned on in conjunction with the operation of the VTR in the reproduction mode. The present invention, when operating the remote control dedicated to the connected equipment,
It is an object of the present invention to provide a television receiver in which the operation contents stored in advance also cause the television receiver to operate in association with each other.

[0004]

According to the present invention, there is provided a remote control signal transmitting section for issuing a remote control signal for switching a mode for storing a remote control signal different from its own dedicated code in the following memory section and a normal use mode, and the remote control. A receiving unit for receiving signals, a memory unit for storing a remote control signal different from its own dedicated code in the storage mode in association with a remote control signal of its own arbitrary dedicated code, and a remote control signal received in the normal use mode A discriminating section for discriminating whether or not the code is a dedicated code for itself, storing the different remote control signal in the memory section when the signal in the storage mode is received, and the memory section when receiving the signal in the normal use mode , A first control unit that controls the discrimination unit and outputs a remote control signal to a second control unit that controls the device body. There is provided a television receiver; and a part. In addition, the mode to be stored,
A signal equivalent to the remote control signal for switching the normal use mode may be generated in the receiver body and input to the first control unit.

[0005]

In the storage mode, the first control section causes the memory section to store the remote control signal of a different code from the receiving section. This memory is stored in association with the operation key on the television receiver side to be linked. In the normal use mode after the storage, the first control unit causes the discriminating unit to discriminate whether or not the signal from the receiving unit is its own dedicated code. The signal is sent to the control unit, and if it is the signal of the stored different code, the corresponding code on the television receiver side is read from the memory unit and sent to the second control unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A television receiver according to the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of essential parts showing an embodiment of a television receiver according to the present invention, and FIG. 2 is a flow chart for explaining the operation of the present invention in a normal use described below. In FIG. 1, 1 is a television receiver main body (hereinafter referred to as “receiver”), 2 is a remote control signal transmission unit dedicated to the receiver 1 (hereinafter referred to as “TV remote controller”), 3
Is a device A connected to the receiver 1, 4 is a remote control signal transmission unit dedicated to the device A3 (hereinafter referred to as "A remote control"), 5
Is another device B connected to the receiver 1, 6 is a remote control signal transmission unit dedicated to the device B 5 (hereinafter referred to as “B remote control”), 7 is a reception unit for receiving remote control signals such as infrared rays,
Reference numeral 8 is a memory section for storing remote control signals from the A remote control 4 and B remote control, and 9 is a determination section for determining whether the remote control signal from the receiving section is of its own dedicated code or the A remote control 4 or the B remote control 6. , 10 is a first control unit for receiving a remote control signal from the receiving unit 7 to control the memory unit 8 and the discrimination unit 9 and outputting a predetermined remote control signal to the second control unit 11, and 11 is a first control unit. A second control unit 12 performs a predetermined circuit control based on a remote control signal from the control unit 10, 12 is a first input terminal of the receiver 1, and 13 is the same / second input terminal.

Next, the operation of the present invention will be described separately for the storage mode and the normal use mode. It is assumed that the remote control codes of the TV remote control 2, the A remote control 4, and the B remote control 6 are different from each other. (1) Storage Mode When the device A is, for example, a VTR, and the VTR is set to the reproduction mode by the A remote controller 4, the power of the receiver 1 is turned on in conjunction with setting the predetermined input terminal (input mode). Suppose. The device A is assumed to be connected to the first input terminal 12 of the receiver 1. The storage mode and the normal use mode of the receiver 1 are switched by a switching signal from the TV remote controller 1 or a switching signal 21 generated on the receiver side 1. This switching signal is input to the control unit 10. Next, the code of the "power key" of the TV remote control 1 and the code of the "selection key of the first input terminal 12" are transmitted, and the code of the "reproduction key" of the A remote control 4 is transmitted. The remote control signals of these codes are received by the receiving unit 7 and reach the memory unit 8 via the control unit 10. That is, by this operation, the power-on code and the selection code of the first input terminal 12 are stored in the memory section 8 in correspondence with the VTR reproduction mode code. Similarly, in the device B, an operation key corresponding to an operation desired to be interlocked is operated on each of the TV remote controller 2 and the B remote controller 6, and both are stored in the memory section 8 in association with each other. It is presumed that the functions frequently interlocked on the receiver side are power on and input mode selection, but channel switching or power off may be used. Also in this case, the corresponding key codes of both the receiver 1 and the remote controller may be stored in association with each other.

(2) Normal use mode FIG. 2 is also used in the following description. The ST number in the sentence represents each step in FIG. When the setting in the storage mode is completed, the TV remote controller 2 (or the receiver 1) returns to the normal use mode by the switching signal. Now, it is assumed that the receiver 1 is in the power-off state, and the VTR (device A3) has been powered on by the A remote controller 2 and then the "playback key" has been operated. A
The remote control signal transmitted from the remote control 2 is received by the receiving unit 7 (ST1) and input to the first control unit 10. The first control unit 10 causes the determination unit 9 to determine whether the signal from the reception unit 7 is its own dedicated code (that is, the signal from the TV remote controller 2) (ST2). If it is determined that the code is not its own code (ST2-NO), the first controller 10 retrieves the memory data corresponding to the code from the memory 8 (ST).
3) If it is the stored data (ST3-YES), the corresponding self code, that is, the code for setting "power on" and "selection of the first input terminal 12" in this example is read ( ST4). The corresponding read code is sent to the second control unit 11 (ST5), the second control unit 11 controls the related circuits to turn on the power, and the input mode is set to the first input terminal 12. Set. When the device B is operated by the B remote controller 6, the same function is executed within the range stored in the storage mode. Since the signal from the TV remote controller 2 is discriminated by the discriminating unit 9 as its own dedicated code (ST2-YES), the first control unit 10 sends the signal from the receiving unit 7 to the second control unit 11 as it is. .. Even if the received signal is determined to be other than its own code, the code not stored in the memory unit 8 does not operate (ST
3-NO). The first control unit 10 and the memory unit 8 described above
The actual implementation of the discriminating unit 9 and the like is a microcomputer. Moreover, the microcomputer is the center of the configuration of the second control unit 11.

[0009]

As described above, according to the present invention, when another device such as a VTR is connected to the television receiver, the remote control operation dedicated to the other device can be performed within a range stored in advance. The television receiver can also be operated in conjunction with each other. Therefore, it is not necessary to individually use a dedicated remote controller, which contributes to the improvement of operability as a system centered on a television receiver.
