Of the functions described above, and such functions are visually represented as block elements in the figure.

Reference numeral 16 denotes a command signal detecting means, which is provided to determine the content of the command signal from the remote control code detected by the infrared light receiving section 17. The command signal here includes not only a command signal for the MON / TV device 1 but also a command signal for an AV device connected to the MON / TV device 1.

Reference numeral 18 denotes input selection state detecting means for detecting which input signal is selected in the video / audio signal switching circuit 11. In the case where the selection state of the input signal can always be grasped by the switching control signal to the video / audio signal switching circuit 11, it is not particularly necessary to provide such an input selection state detecting means. Of course.

Reference numeral 19 denotes registration control means. When the learning mode is formed by a user operation, the command signal detection means 16
The corresponding data is stored in the memory 20 by associating the command signal relating to the AV device detected by the above with the television operation desired to be associated with the command signal. Further, in the interlocking operation mode, when a registered command signal is detected, data indicating the television operation associated with the command signal is read from the memory 20,
The learned operation contents are executed by the operation control means 15, and the switching of the video / audio signal switching circuit 11 is controlled by the input selection control means 21, and a predetermined signal is selected.

Reference numeral 22 denotes a power supply operation control means provided so that a power supply operation can be automatically performed in the interlocking operation mode. The power supply state detection means 23 and the operation control means 15 detect power on / off states. The on / off control of the power supply circuit 24 is performed according to a signal from the power supply circuit 24.

(C. Operation) [FIGS. 3 to 7] Next, the operation of the MON / TV device 1 will be described separately for a learning mode and an interlocking operation mode.

(C-1. Learning Mode) [FIGS. 3 to 6] (c-1-a. Processing Example 1) [FIG. 3] FIG. 3 is a flowchart showing an example of a processing flow in the learning mode. is there.

a) “Start” The user needs to clarify in advance what kind of operation function of the MON / TV device 1 is to be associated with the command signal related to the AV device. For example, by operating the remote commander 7, "PLA" of the VTR (I)
It is assumed that the MON / TV apparatus 1 wants to automatically select channel 2 when the "Y" button is pressed (note that VTR (I)
It goes without saying that the RF signal to be output is selected as the VHF 2ch signal.)

b) “Select a channel.” First, the MON / TV apparatus 1 selects a channel to be associated with and displays it on the screen. For example, when two channels are selected, a screen on which a channel is displayed appears.

c) "Set the learning mode." When the learning button of the remote commander 6 is pressed, the corresponding remote control code is identified by the command signal detecting means 16, and the learning mode is established.

d) "Input a command signal related to the AV device." That is, the user operates the remote commander of the desired AV device (in this example, indicates the VTR (I)) and selects the command signal to be associated.

That is, when the "PLAY" button is pressed by operating the remote commander 7, the corresponding remote control code is displayed on the VTR.
(I) Detector and Command Signal Detecting Means of MON / TV Device 1
Detected by 16.

When the target AV device is a playback device such as a VTR or LDP, a signal is output to the outside by a playback operation. However, in the case of a BS tuner, a channel selection operation may be performed.

e) "The channel selection and the command signal of the AV device are stored in association with each other." When the command signal detecting means 16 detects the remote control code and determines its content, the registration control means 19 transmits the command signal and the command signal. Memory corresponding to channel selection
Remember at 20.

Table 2 conceptually shows an example of the registration form of the data stored in the memory 20.

The remote control code by the operation of the remote commander usually has category data and command data. The category data distinguishes the AV device, and the command data distinguishes the operation content.

In the above example, in response to the "PLAY" operation of the "VTR (I)", the channel selection of two channels and the video / audio signal switching circuit
The selection of the tuner output at 11 is associated with the registration operation.

The completion of such association is notified to the user by changing the display color of the channel display. For example, the channel display, which was previously green, is changed to cyan, and the completion of the setting is visually displayed to the user.

f) “Cancel the learning mode.” Pressing the learning button of the remote commander 6 again cancels the learning mode.

(C-1-b. Processing Example 2) [FIGS. 4 to 6] FIG. 4 is a flowchart showing a processing example in which learning contents can be interactively input and registered. 5 (A) to 5 (E) show an example of a screen display at times during the processing.

a) “Set the learning mode.” When the learning mode is formed by pressing the learning button of the remote commander 6, for example, “learning” as shown in FIG.
Is displayed on the screen to inform the user that the learning mode has been set.

b) “Input a command signal related to AV equipment” A command signal is generated by operating a remote commander related to a desired AV equipment, and this is detected by the command signal detection means 16 of the MON / TV apparatus 1, and the category and the operation content are determined. Be identified.

For example, when the "PLAY" button of the VTR (I) is operated, as shown in FIG. 5 (B), a display for prompting the user to perform what kind of processing for the operation is displayed. .

c) “Perform an operation for an operation to be executed in connection with a command signal.” That is, the operation is performed for an operation content to be associated with a command signal.

For example, "PLAY" of the remote commander 7 of the VTR (I)
To turn on the power of the MON / TV device 1 when the button is pressed, the power button of the MON / TV device 1 is pressed.

Then, as shown in FIG. 5 (C), “PLA” of VTR (I)
When the "Y" button is pressed, a screen is displayed to turn on the power.

d) "Is there an operation to be further associated and executed?" It is asked whether there is an operation to be further associated with the command signal input in step b). If not, the process proceeds to the next step e). If yes, return to step c).

At this time, for example, as shown in FIG. 5 (D), whether or not there is an operation to be further learned is displayed on the screen. When it is desired to select two channels as the operation content, press the channel button. .

Such an operation may be performed using the remote commander 6, or may be performed using an operation switch provided on the MON / TV device 1 body.

When all the actions to be learned are completed, as shown in FIG. 5 (E), the content just learned (that is, the VTR)
(I) Turn on the power and select channel 2 when pressing the "PLAY" button in (I)) is displayed on the screen.

e) "The command signal of the AV device and the operation content of the MON / TV device 1 are stored in association with each other." That is, the command signal selected in step b) is associated with the operation content operated in step c). Stored in the memory 20.

For example, the registration form in the memory 20 is as shown in Table 3.

f) "Release the learning mode." By pressing the learning button again, the learning mode is released and that effect is displayed on the screen.

In the above-described example, after the command signal is input, the operation related to the operation to be performed is performed. However, this procedure may be performed in reverse. For example,
Assuming that a screen display asking as shown in FIG. 6 (A) is made after the learning mode is formed, if a channel selection operation is first performed on the two channels, a screen as shown in FIG. 6 (B) is displayed. When the "PLAY" button of the VTR (I) is pressed by using the remote commander 7, the learning content may be completed and a message to that effect may be displayed as shown in FIG. 6 (C).

(C-2. Linked Operation Mode) [FIG. 7] FIG. 7 is a flowchart showing the flow of processing in the linked operation mode.

Note that the MON / TV device 1
May be automatically set after the completion of the learning in, or an operation switch for forming / cancelling the interlocking operation mode may be newly provided.

a) "Is a command signal detected?" It is determined whether or not a command signal is detected by the command signal detecting means 16. If detected, the process proceeds to the next step b). If not, the command signal detecting operation is performed. repeat.

b) “Is a registered command signal?” It is determined whether the detected command signal has been registered in the memory 20. If the detected command signal has been registered, the process proceeds to step c). No processing related to this is performed.

c) “Perform the associated operation.” Data indicating the operation content of the MON / TV device 1 corresponding to the command signal is read from the memory 20 to the operation control means 15, and
A learning operation is performed.

For example, in the example shown in Table 2, channel selection is performed by a signal transmitted from the operation control unit 15 to the channel selection unit 13, and the video / audio signal switching circuit 11 is controlled by the input selection control unit 21. Tuner at 12
After the output is selected, it passes through the video / audio signal processing circuit.
Output to CRT and speakers.

In the example shown in Table 3, when the "PLAY" button of the remote commander 7 is pressed, the power of the MON / TV device 1 is turned on, and channel selection of two channels and selection of a tuner output are performed. That is, since the power state detection means 23 always knows the power state of the MON / TV device 1, the power operation control means 22
If the power is on, the state is kept as it is, and if the power is off, a signal is sent to the power supply circuit 24 to turn on the power.

(G. Effects of the Invention) As is apparent from the abnormal description, the monitor / television device of the present invention has an input terminal to which a signal from an audio / visual device is input, and a command for designating an operation function. And a command signal detecting means for detecting a command signal issued by a remote command means to an audio / visual device connected to an input terminal to determine the content of the command. When an operation function of a monitor / television device to be associated with a command signal for an audio / visual device is specified by the command means, the command signal and the specified operation content are stored in the memory means in association with each other. Registration control means and the command signal detected by the command signal detection means are registered. If the control means has already registered in the memory means, operation control means for reading out data indicating the operation content corresponding to the command signal from the memory means to grasp and execute the registered operation.
