Description

[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to a television receiver that stores its own remote control signal in correspondence with input remote control signals of other AV equipment, and controls itself in accordance with remote control operations of other AV equipment. .

0002

2. Description of the Related Art: The specified model is determined by checking the identification code that constitutes the input remote control signal, and for the own remote control signal, a control procedure corresponding to the control code following the identification code is executed. Remote control signals from other companies' products and other models were ignored.

0003

[Problem to be Solved by the Invention] Since it does not operate in response to remote control signals that control other models, in an AV system that combines various devices, it is necessary to use a separate remote control transmitter for each device, or to control the remote control signal of each device. This method uses a learning type remote control that receives and stores a remote control signal and transmits the stored remote control signal by pressing the corresponding key, which is cumbersome to operate and requires the separate purchase of a remote control transmitter. Further, since one key corresponds to only one control of one device, an AV system that combines a plurality of devices requires a plurality of key operations for one operation.

0004

[Means for Solving the Problems] A control section of the television receiver is put into a registration mode by key operation on the remote control transmitter or key input section of the television receiver, and the control section is made to correspond to the input remote control signal of another device and the same remote control signal. A remote control signal is supplied and stored in a non-volatile memory within the control unit. Confirm that the remote control signal of another device input in the non-registration mode is stored in the non-volatile memory, read out the stored remote control signal of the TV receiver in correspondence with the remote control signal, and read the remote control signal of the TV receiver in correspondence with the remote control signal. If the main power supply is OFF, it is turned ON, the read remote control signal is decoded, and the control specified by the remote control signal is executed. Furthermore, in response to a remote control signal of the own machine input in the non-registration mode, the main power supply of the own machine is checked, and if it is in the OFF state, it is turned ON and then the control specified by the remote control signal is executed.

[Operation] The tuner unit 12 selects the signal of the channel specified by the output of the control unit 15 from the broadcast signal input to the antenna input terminal 11, and demodulates the video and audio signals or the video and audio input to the external input terminal 13. One of the signals is selected by the output of the control section 15. The control section 1
The video and audio signals selected at the output of step 5 are passed through a video amplification section and an audio amplification section, respectively, and the respective output signals are reproduced by a cathode ray tube and a speaker.

The control section 15 receives an operation signal corresponding to the operated key of the key input section 16, decodes the signal, executes a control procedure corresponding to the signal, and outputs a control signal 17. The infrared remote control signal 22 corresponding to the operation key outputted from the remote control transmitter 21 is captured by the remote control signal receiving unit 18 of the television receiver 10, the demodulated remote control signal is decoded by the control unit 15, and the key input unit 16 decodes the demodulated remote control signal. Similarly to the input operation signal, the control signal 17 of the control item specified by the same signal is output.

As shown in FIG. 2, the remote control signal 22 consists of a header section indicating the start of the signal, an identification code specifying the manufacturer and model of the device to be controlled, and a control code specifying control items for the specified device. The device that receives the remote control signal 22 uses the identification code to determine whether or not it is its own remote control signal, executes the control procedure specified by the control code following the identification code for the remote control signal of its own device, and then The control signal 17 for the control item specified by the signal is output, and remote control signals from other devices are ignored.

[0008] Remote control signal 22 corresponding to the registration key of the remote control transmitter 21 of the television receiver or key input section 16
The control unit 15 that receives the operation signal of the registration key puts its own operation in the registration mode. The control unit 15 in the registration mode receives and stores the remote control signal from the remote control transmitter of another device and the remote control signal from the own remote control transmitter according to the control procedure shown in FIG. That is, a timer that is reset each time the remote control signal 22 is input is activated, the time during which the remote control signal 22 is not input is counted, and the registration mode is terminated after a predetermined period of time has elapsed.

The control unit 15 checks the identification code of the remote control signal 22 input in the registration mode, and if it is from another device, the control unit 15 determines that the remote control signal 22 is not stored in the nonvolatile memory within the control unit 15. Make sure that. Further, if the remote control signal of the own machine is stored in the temporary storage memory set in the memory in the control unit 15, the remote control signal of the own machine temporarily stored in the control unit 15 is made to correspond to the input remote control signal 22 of other equipment. If the contents of the simultaneous storage memory are not the remote control signal of the device itself, the contents of the simultaneous storage memory are updated with the input remote control signal 22 of the other device.

[0010] If the remote control signal 22 inputted in the registration mode of the control section 15 is that of the own device, and the remote control signal of another device is already stored in the temporary storage memory,
Similarly to the above, the own remote control signal inputted in correspondence with the temporarily stored remote control signal of another device is stored in the non-volatile memory in the control unit 15, and if the contents of the simultaneously stored memory are not the remote control signal of the other device, the signal is input. Update the contents of the simultaneous storage memory using the own remote control signal.

FIG. 4 shows a control procedure of the control section 15 using the input remote control signal 22 in the non-registration mode which is the normal control mode of the control section 15. That is, the identification code of the input remote control signal 22 is checked to determine whether it is the remote control signal of the own machine, and if it is the remote control signal of the own machine, the remote control signal 22 is decoded using the conventional control procedure and the corresponding control is performed. The control signal 17 corresponding to the item specified by the control code of the remote control signal 22 is output according to the procedure. Even when inputting a remote control signal from one's own device, before executing the control procedure for decoding control of the remote control signal 22, check whether the main power of the own device, that is, the television receiver 10, is in the ON state, and if it is in the OFF state, the same Power ON control signal 17
Output.

If the input remote control signal 22 is from another device, the same remote control signal 22 is compared with the remote control signal stored in the non-volatile memory, and if they match, it is stored in correspondence with the same remote control signal 22. Read out the remote control signal of your own machine. Regarding the read remote control signal of the own machine, check the main power of the own machine in the same way as when inputting the same remote control signal, and if it is OFF, turn on the main power of the own machine.
After that, the conventional control procedure for the remote control signal is executed, and the corresponding control signal 17 is output.

For example, a remote control signal for selecting an external input of the television receiver 10 of the present invention is made to correspond to a remote control signal of "playback" of the VTR 20 connected to the external input terminal 13 of the television receiver 10 of the present invention. It is assumed that it is stored in non-volatile memory. When the VTR 20 is in operation and a recorded tape is loaded, a remote control signal for "playback" of the VTR 20 is sent from the remote control transmitter of the VTR 20, and the VTR 20 is put into the playback state.

[0014] At the same time, the television receiver 10 which has received the remote control signal for "playback" of the VTR 20 reads out the remote control signal for external input selection of its own device stored in the nonvolatile memory in correspondence with the remote control signal. The state of the main power supply of the television receiver 10 is checked and turned on, and the reproduction signal of the VTR input to the external input terminal 13 is selected according to the specification of the remote control signal and reproduced by the cathode ray tube and speaker.
