Hereinafter, an example of the procedure of the abnormality handling process executed by the liquid crystal television receiver X and the bidirectional remote controller Y in the television system Z will be described with reference to the flowchart of FIG. 3 and the display example of FIG. To do. The liquid crystal television receiver X and the bidirectional remote controller Y execute various processes executed by a general liquid crystal television receiver and the bidirectional remote controller in addition to those described here.
Here, S1, S2,... In FIG. 3 (a) are identification codes of processing procedures (steps) executed by the remote control side control circuit 150 of the bidirectional remote controller Y, and S11, FIG. S12,... Represent identification codes of processing procedures (steps) executed by the sub-microcomputer 18 of the liquid crystal television receiver X. The process executed by the sub-microcomputer 18 may be executed by the television control circuit 8.
4A and 4B show display examples of abnormal contents, FIGS. 4C and 4D show display examples of action contents, and FIG. 4E shows display examples of operation history. .

(Step S1, Step S11)
First, in the bidirectional remote controller Y, the remote controller side control circuit 150 is waiting for reception of an abnormality occurrence signal from the liquid crystal television receiver X (No side of S1). Then, in response to the reception of the abnormality occurrence signal (Yes side of S1), the remote controller side control circuit 150 shifts the processing to step S2.
On the other hand, in the liquid crystal television receiver X, the sub-microcomputer 18 is waiting for occurrence of a predetermined abnormality preset in the liquid crystal television receiver X (No side in S11). Then, in response to the occurrence of the predetermined abnormality (Yes side of S11), the sub-microcomputer 18 shifts the processing to step S12.
Here, a case where the predetermined abnormality is preset to be an abnormality of the power supply circuit 17 will be described as an example. This is because when the power supply circuit 17 is abnormal, if the liquid crystal television receiver X is operated as it is, there is a high possibility that the liquid crystal television receiver X is seriously damaged. The predetermined abnormality is not limited to the abnormality of the power supply circuit 17, but may be an abnormality in which it is not desirable to turn on the liquid crystal television receiver X, such as an abnormality of the inverter circuit of the light source driving circuit 20, for example. That's fine. In this case, the sub-microcomputer 18 is configured to detect the predetermined abnormality.

(Steps S12 to S13)
If an abnormality of the power supply circuit 17 is detected by the sub-microcomputer 18 in the step S11 (Yes side of S11), the process proceeds to step S12, and the sub-microcomputer 18 is An abnormality occurrence signal is transmitted to the bidirectional remote controller Y. The abnormality occurrence signal includes information regarding the content of the abnormality that has occurred in the liquid crystal television receiver X, such as the occurrence of an abnormality in the power supply circuit 17 and the date and time of occurrence of the abnormality.
Here, when the power key 151a is pressed among the operation keys 151 provided on the bidirectional remote controller Y, the abnormality occurrence signal is transmitted from the bidirectional remote controller Y so as not to transmit a power operation signal corresponding to the power key 151a. This corresponds to the operation key setting information related to the setting of the processing content when the power key 151a is pressed. Here, the sub-microcomputer 18 when executing the transmission processing corresponds to the operation key setting information transmission means.
Thereafter, the sub-microcomputer 18 waits for reception notification from the bidirectional remote controller Y (No side in S13).

(Step S2, Step S14)
Then, when the abnormality occurrence signal transmitted from the liquid crystal television receiver X is received by the wireless module 152 (Yes side of S1), the remote control side control circuit 150 generates the abnormality in the subsequent step S2. A reception notification for notifying that the signal has been received is transmitted to the liquid crystal television receiver X by the wireless module 152.
Thus, when the reception notification transmitted from the bidirectional remote controller Y is received by the wireless module 9 (Yes side of S13), the sub-microcomputer 18 in step S14, the liquid crystal television receiver X The TV side control circuit 8 is caused to execute a shutdown process for turning off the power of the TV. Of course, the shutdown process may be executed by the sub-microcomputer 18. In addition, after the shutdown, the operation of the power key provided on the main body of the liquid crystal television receiver X is continued until a predetermined recovery operation such as plugging / unplugging of the AC cord or a long pressing operation of a predetermined key is performed. It may be invalid.
In step S13, if the reception notification is not received for a predetermined time or more, it is desirable to ensure safety in the liquid crystal television receiver X by forcibly executing step S14.

(Steps S15 to S16)
Thereafter, the sub-microcomputer 18 waits for recovery from the abnormality (No side of S15). For example, the sub-microcomputer 18 determines whether or not an abnormality has been restored according to whether or not a restoration signal has been input from the power supply circuit 17 or the television control circuit 8.
Here, if it is determined that the abnormality has been recovered (Yes in S15), the process proceeds to step S16, and the sub-microcomputer 18 transmits an abnormality recovery signal to the bidirectional remote controller Y by the wireless module 9. To do.

(Step S3)
On the other hand, in step S3, the remote control side control circuit 150 indicates the abnormality content generated in the liquid crystal television receiver X to the display unit 153 based on the abnormality occurrence signal received from the liquid crystal television receiver X. Display. The abnormality content is not limited to being displayed in response to the reception of the abnormality occurrence signal, but may be displayed in response to, for example, a predetermined operation of the operation key 151 by the user. Here, the remote-control-side control circuit 150 when executing such display processing corresponds to information display means.
Here, since an abnormality has occurred in the power supply circuit 17, a warning or an error code indicating that there is an abnormality in the power supply circuit is displayed as shown in FIG. At this time, information useful for maintenance such as a telephone number of the support center is also displayed on the display unit 153. In addition, for example, when the abnormality occurrence signal indicates that the inverter circuit of the light source drive circuit 20 is abnormal, a warning to that effect is displayed on the display unit 153 as shown in FIG. Is displayed.
At this time, the remote control circuit 150 may display a measure to be taken in response to the abnormality occurrence signal, for example, in response to an operation of the operation key 151 by the user. The contents of the measure may be included in the abnormality occurrence signal, or may be stored in advance in the ROM 150b of the remote control circuit 150 as corresponding to the abnormality occurrence signal. Good. For example, as shown in FIGS. 4C and 4D, the action contents such as “Please re-insert the AC code” and “Please upgrade the software” are displayed.

Further, the abnormality occurrence signal includes log information (an example of the operation history information) regarding the operation history in the liquid crystal television receiver X, and the remote control side control circuit 150 performs a predetermined operation key 151 by the user. It is also conceivable to display the log information on the display unit 153 according to an operation. Further, the log information may be displayed together with the display of the abnormality content in step S3.
Here, the remote-control-side control circuit 150 when executing such display processing corresponds to information display means. FIG. 4E shows an example of log information recorded at any time in the liquid crystal television receiver X. At this time, the details of the log information can be referred to by selecting each log information on the display screen of the log information.
Thereby, even in a situation where the power of the liquid crystal television receiver X cannot be turned on, the log information of the liquid crystal television receiver X can be referred to, for example, early investigation of the cause of the abnormality can be performed. .
In addition, when the liquid crystal television receiver X is operating normally, the log information is periodically transmitted from the liquid crystal television receiver X to the bidirectional remote controller Y, and the internal memory of the bidirectional remote controller Y is stored. In another embodiment, the remote controller side control circuit 150 may read the log information from the memory and display it on the display unit 153 when an abnormality occurs.

(Step S4)
Next, in step S4, the remote control circuit 150 sets the processing content when the operation key 151 is pressed in accordance with the abnormality occurrence signal transmitted from the liquid crystal television receiver X. Here, the remote control side control circuit 150 when executing such processing corresponds to the operation key processing content setting means.
Specifically, the remote controller side control circuit 150 determines the processing contents when the power key 151a among the operation keys 151 is pressed from the process of transmitting the original power operation signal to the power supply of the liquid crystal television receiver X. Change to provisional processing that does not involve the input of. For example, it is conceivable that the provisional process does not transmit any signal to the liquid crystal television receiver X and invalidates the original processing function of the power key 151a. The changed processing contents are stored in the nonvolatile memory 150c of the remote control side control circuit 150, and then the remote control side control circuit 150 performs temporary processing based on the changed contents when the power key 151a is pressed. Execute.
Here, the provisional process is a display process for displaying that an abnormality has occurred in the liquid crystal television receiver X and that the power operation of the liquid crystal television receiver X is restricted for that purpose. Suppose there is. The provisional process is not limited to the display process, but is another process that does not involve turning on the power of the liquid crystal television receiver X, or simply depressing the operation of the power key 151a. It's okay.

(Steps S5 to S7)
Thereafter, in step S5, the remote control control circuit 150 determines whether or not the power key 151a has been pressed. If it is determined that the power key 151a has been pressed (Yes in S5), the process proceeds to step S6. If the power key 151a has not been pressed (No in S5), the process proceeds to step S6. The process proceeds to S7.
In step S6, the remote control circuit 150 executes processing according to the processing content when the power key 151a is pressed after being changed in step S4. That is, here, no signal is transmitted to the liquid crystal television receiver X even when the power key 151a is pressed, and an abnormality has occurred in the liquid crystal television receiver X. A display process for displaying that the power supply operation of the liquid crystal television receiver X is restricted is executed. Therefore, it is compulsory that the liquid crystal television receiver X is started up in an abnormal state regardless of the user's intention to turn on the power of the liquid crystal television receiver X by operating the power key 151a. To be blocked.
On the other hand, in step S <b> 7, the remote control side control circuit 150 determines whether an abnormality recovery signal from the liquid crystal television receiver X is received by the wireless module 152. If it is determined that the abnormality recovery signal has been received (Yes in S7), the process proceeds to step S8. If the abnormality recovery signal has not been received (No in S7), the process Is returned to step S5.

(Step S8)
In step S8, the remote control side control circuit 150 restores the processing content when the operation key 151 changed in step S4 is pressed. Here, the remote control side control circuit 150 changes the processing content when the power key 151a is pressed down to the transmission processing of the power operation signal to the original liquid crystal television receiver X. Note that, when an abnormal content or the like is displayed on the display unit 153, the remote control side control circuit 150 ends the display.
Thereby, when the power key 151a is subsequently pressed, a power operation signal corresponding to the power key 151a is transmitted to the liquid crystal television receiver X, and the power source of the liquid crystal television receiver X is turned on.

As described above, in the television system Z, when a predetermined abnormality such as an abnormality in the power supply circuit 17 occurs in the liquid crystal television receiver X, an abnormality transmitted from the liquid crystal television receiver X is detected. Since the processing content when the operation key 151 is pressed in the bidirectional remote controller Y is changed by the generated signal, even if the power key 151a is pressed by the user after the occurrence of the abnormality, the original function of the power key 151a The operation of turning on the power of the liquid crystal television receiver X is not performed, and the deterioration of the abnormal state of the liquid crystal television receiver X can be prevented.
Further, since the contents of the abnormality are displayed on the bidirectional remote controller Y, the user can easily grasp the reason why the liquid crystal television receiver X is not turned on when the power key 151a is pressed.

By the way, in the present embodiment, a case has been described in which the processing content is changed so as not to transmit a signal when the power key 151a is pressed in step S4. However, for example, when the power key 151a is pressed, the original content is changed. Instead of a power operation signal transmitted when the power key 151a is pressed, a safe mode activation signal for activating the liquid crystal television receiver X in a safe mode that restricts the functions of the liquid crystal television receiver X than usual is transmitted. It is also possible to change the processing contents.
Thereby, the liquid crystal television receiver X operates in a safe mode in which the function is restricted more than usual (for example, the operation of the liquid crystal display panel 16 or the like is restricted) in response to reception of the safe mode activation signal. Therefore, if no abnormality has occurred within the operation range, various processes such as inspection of abnormal parts and collection of abnormality occurrence history information can be executed in the safe mode.
In addition, a communication interface such as a USB is provided in the bidirectional remote controller Y, and a user can report abnormal contents or operation history of the liquid crystal television receiver X from the bidirectional remote controller Y to the personal computer via the communication interface. A configuration capable of transmission is also conceivable. As a result, for example, abnormal contents and operation history of the liquid crystal television receiver X transmitted from the bidirectional remote controller Y to the personal computer can be transmitted from the personal computer to a maintenance organization such as a support center by e-mail or the like. Therefore, it is possible to quickly solve the abnormal contents of the liquid crystal television receiver X.

In this embodiment, when the bidirectional remote controller Y is a general-purpose product compatible with the liquid crystal television receiver X of various manufacturers, the bidirectional remote controller Y automatically corresponds to the liquid crystal television receiver X. The structure which can be made to be demonstrated is demonstrated. In addition, the same code | symbol is used about the component similar to the component demonstrated in the said embodiment.
Hereinafter, an example of a remote control code setting process executed by the bidirectional remote controller Y and the liquid crystal television receiver X will be described with reference to the flowchart of FIG. In FIG. 5A, S21, S22,... Are processing procedure (step) numbers by the remote control side control circuit 150 of the bidirectional remote controller Y, and S31, S32,. The processing procedure (step) number by the TV side control circuit 8 is shown. Of course, the processing executed by the television control circuit 8 in the remote control code setting processing may be executed by the sub-microcomputer 18.

(Step S21, Step S31)
First, in the bidirectional remote controller Y, the remote controller side control circuit 150 waits for reception of a remote controller code signal to be described later transmitted from the liquid crystal television receiver X (No side of S21). Then, in response to the reception of the remote control code signal (Yes side of S21), the remote control side control circuit 150 shifts the processing to step S22.
On the other hand, in the liquid crystal television receiver X, the television-side control circuit 8 determines whether or not a new bidirectional remote controller exists within the communicable range of the wireless module 9 by the wireless module 9. (S31). For example, when the wireless module 9 receives a response signal from a bidirectional remote controller other than the bidirectional remote controller registered as currently communicable in step S34 described later by transmitting a detection signal at predetermined intervals. Therefore, it is determined that there is a new bidirectional remote control. At this time, the wireless module 9 identifies the bidirectional remote controller based on identification information included in the response signal.
If it is detected in step S31 that a new bidirectional remote controller is present (Yes in S31), the process proceeds to step S32.

(Steps S32 and S33)
In step S <b> 32, the television-side control circuit 8 transmits a remote control code signal indicating the manufacturer of the liquid crystal television receiver X to the bidirectional remote controller Y by the wireless module 9. Thereafter, the television control circuit 8 waits for reception notification from the bidirectional remote controller Y (No side in S33).
The remote control code signal is used to provide consistency of the operation signal when the correspondence relationship between the transmitted and received operation signals is different, such as when the manufacturers of the liquid crystal television receiver X and the bidirectional remote control Y are different. This information is stored in advance in the ROM 8b of the TV side control circuit 8 or the like. Here, the remote control code signal is an example of operation key setting information related to setting of processing contents when the operation key 151 provided on the bidirectional remote controller Y is pressed.

(Steps S22 and S34)
In the bidirectional remote controller Y, the remote controller control circuit 150 receives the remote controller code signal transmitted from the liquid crystal television receiver X by the wireless module 152 (Yes in S21). The process proceeds to step S22.
In step S <b> 22, the remote control side control circuit 150 transmits a reception notification indicating that the remote control code signal has been received together with the identification information of the bidirectional remote control Y to the liquid crystal television receiver X by the wireless module 152.
In the liquid crystal television receiver X, the television-side control circuit 8 determines that the reception notification has been received by the wireless module 9 (Yes in S33), and the process proceeds to step S34.
In step S34, the television control circuit 8 registers the identification information of the bidirectional remote controller Y included in the reception notification in the nonvolatile memory 8c or the like. Thereby, thereafter, the bidirectional remote controller Y is handled as a remote controller that can communicate with the liquid crystal television receiver X.

(Step S23)
On the other hand, in the bidirectional remote controller Y, the remote control side control circuit 150 changes the content of the operation signal transmitted to the liquid crystal television receiver X when the operation key 151 is pressed in accordance with the remote control code signal. Here, the remote control side control circuit 150 when executing such processing corresponds to the operation key processing content setting means.
Specifically, correspondence information in which the contents of the remote control code signal and the operation signals of each of the operation keys 151 are associated with each other is stored in advance in a memory such as the ROM 150b and the nonvolatile memory 150c in the remote control circuit 150. Therefore, it is conceivable that the remote control side control circuit 150 sets an operation signal to be transmitted when the operation key 151 is pressed based on the received remote control code signal and the correspondence information. The content of the correspondence information may be included in the remote control code signal.
As described above, the processing content when the operation key 151 is pressed in the bidirectional remote controller Y, that is, the content of the operation signal to be transmitted is changed according to the remote control code signal received from the liquid crystal television receiver X. By doing so, it is possible to save the user from having to set the manufacturer of the liquid crystal television receiver X in the bidirectional remote controller Y.
