Consequently, remote control based upon another remote controller can be executed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application] The present invention relates to a television receiver that stores remote control signals from remote control devices of other models and enables remote control control using the same remote control device.

[Conventional technology]

The code of the input remote control signal is compared with the data stored in advance in the memory in the control unit 1, and only when they match, the control signal corresponding to the same code is output, and the remote control signals of other models are ignored. Ta.

A remote controller called a learning remote controller stores a remote control signal input in memory mode in correspondence with a designated key on the learning remote controller, and when the same key is operated, a stored remote control signal corresponding to the key is output. .

In addition, some remote control devices for VTRs are equipped with TV operation keys, but they can only be used to remotely control models specified by the same VTR manufacturer.

[Problem to be solved by the invention]

Since it does not operate in response to remote control signals output from remote control devices of other devices, in an AV system that combines the necessary AV devices, it has been necessary to prepare and use a remote control device for each device.

A learning type remote control that receives and stores remote control signals output from the remote controller of each device and outputs the received and stored remote control signals by pressing the corresponding key must be purchased separately and cannot be stored in the learning type remote controller. The operation was also cumbersome.

In addition, in the remote controller, one key corresponds to only one control of one device;
Some V-systems required multiple key operations for -operations.

[! Means to solve problem I]

Set the control unit to the registration mode by operating the remote controller of the own device or the key input unit, and set the display screen to the remote control signal registration screen, and follow the message on the screen to input the remote control signal of the other device input with the cursor. The control items are stored in a non-volatile memory provided in the control unit in correspondence with the control items displayed on the screen.

The remote control signal of another device input in the normal mode is compared with the signal stored in the non-volatile memory, and if the signal matches, a control signal corresponding to the control item of the own device is output, and the signal of the signal source device such as a VTR is output. By specifying the video input selection corresponding to the output remote control signal, the television receiver is turned on and the specified video input is selected.

[Effect]

The tuner section I2 selects the signal of the channel specified by the channel selection signal 16a output from the control section 15 from the television broadcast signal input to the antenna input terminal 11, and outputs a demodulated video signal.

One of the video signals input to the external video input terminal 13 or the video signals output from the tuner section 12 is designated and selected by the selection signal 16b output from the control section 15.

On the other hand, a display signal of characters or symbols to be displayed on the cathode ray tube 20 is generated based on the data outputted from the control section I5, and a composite signal with the video signal selected by the input switching section 14 or each individual signal is sent via the video signal section.

converts the same signal into digital data, and outputs a control signal 16az16c corresponding to the same data, similar to the operation signal outputted by the key input section 2I.

As shown in FIG. 2, the remote control signal 23a is composed of a part of a header indicating the start of the signal, a custom code given to each manufacturer and model of AV equipment, and a data code indicating control details of the same model.

Therefore, remote control signals issued from remote controllers of different models are identified by the custom code of the same signal, and remote control signals of different models are ignored, so that the same signal will not be activated.

The present invention provides, in an AV system composed of a plurality of AV devices centered around a television receiver, a remote control signal output from a remote control device of a device other than the television receiver.
The control code for the control item of the television receiver specified by the cursor on the display screen in the registration mode is stored in the nonvolatile memory 15a in the control unit I5, and the remote control signal for equipment other than the television receiver input in the normal mode is stored in the same nonvolatile memory. The signal is compared with the signal stored in the memory 15a, and when the signal matches, a control signal corresponding to the corresponding control item of the television receiver is outputted to perform a specified control operation, and a signal is output from a signal source device such as a VTR. For example, if you specify the external input of the video signal corresponding to the remote control signal for playback operation, turn on the power of the TV receiver, select the specified video input, and control only with a remote controller of a different model. First, it also enables simple system control.

That is, the control section 15 of the television receiver is put into the registration mode by key operations on the remote controller 23 or the key input section 2I of the television receiver, and the output of the remote controller of the other device is performed according to the control procedure shown in the flowchart of FIG.

A corresponding control signal 16c is generated and output in the same manner as in the conventional control procedure.

The input remote control signal 23a is transmitted to the non-volatile memo UI5.
If the remote control signal of another device is a control signal for the video signal output mode of the signal source device that corresponds to the external input selection of the own device's video signal, for example, when playing a VTR, perform the following control. .

That is, i1! determines whether the power of the television receiver is ON.
If the TV receiver is in the OFF state, the control signal 16c to turn on the power is output to put the television receiver into operation. Next, it is checked whether the external input of the video signal is selected, and if another input is selected. If so, input the video signal from the signal source device and select the external input.

(Example) The television broadcast signal input to the antenna input terminal 1 and the tuning signal 16a output from the control unit I5 are transmitted to the tuner unit 12.
