[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a remote control system to which the present invention is applied, and shows the receiver body 20 side that receives television signals in a captain system, for example, and the handheld controller 10 side.

1 no is a keyboard, this keyboard 1 no is,
A large number of various operation keys are provided for remote control. The operation signal generated by the key operation is input to the transmission circuit 12, converted into a modulated transmission signal, and output as an optical signal by the light emitting means 13, for example. The optical signal is received by the light receiving means 2 of the receiver body 2o and converted into an electrical signal, and this electrical signal is amplified by the amplifier 22 and then input to the receiving circuit 24 via the low-pass filter 23. Ru. The reception circuit 24 demodulates the input electrical signal, and the tone signal is input to the microprocessor 25.

The microprocessor 25 digitally decodes the demodulated signal and determines which operation key has been operated. Then, a control signal for controlling the receiver body is outputted according to the content of the determination. Controls for the receiver main body 20 include reading data from the character memory 2' and displaying it on the screen, setting reception channels, and controlling pages of received data.

Further, when the microprocessor 25 identifies the operated key, it determines the instruction content to be operated next based on the instruction content. Then, operation key instruction data is generated for displaying all of the operation keys that can be given instruction contents to be operated next. This operation key instruction data is input to the decoder 26, converted into data, and input to the display key signal generation circuit 22. In the display key signal generation circuit 27, a data arrangement convenient for transmission is set, and the output display key signal becomes a modulation signal in the transmission circuit 28. This modulated signal is output as an optical signal by the light emitting means 29, for example. This optical signal is received by the light receiving means J4 on the hand controller 10 side and converted into an electrical signal.

This electrical signal is amplified by the amplifier 15 and then input to the receiving circuit 17 via the low-pass filter J6. The reception circuit 17 performs demodulation processing on the input electrical signal, and the demodulated signal is decoded by the decoder 18 and input to the display key setting circuit 19.

The display key setting circuit 19 drives and lights up the display section of the operation key that can give an instruction to be operated next.

As described above, according to the present system, when a certain operation key is operated, all the next operable operation keys are indicated on the keyboard 1 at hand by the light emitting means. Therefore,
As long as the displayed keys are operated, even if the user does not know the details of the operation procedure, the user will not make any erroneous operations. In particular, in systems that require key operations many times, it is difficult for users to memorize detailed operating procedures, and users may accidentally omit operating steps.
There was a problem that the next process operation was performed and the process had to be restarted from the beginning, but this system solves this problem.

Next, a specific example in which the above system is used will be described.

Let's take as an example the operating procedure when a user uses the Captain System to find out what kind of science fiction movies are available in region A from July to September.

FIG. 2 shows the transition of display contents on a television screen.

In step SJ, the user operates the introduction key of the all information menu. This can be done, for example, by inputting a code signal by operating a plurality of keys, and by operating these keys, a display introducing a full information menu is displayed on the television screen.

Therefore, at the beginning of this operation, the microprocessor 25
is determined to be the initial state of the system, and all operation keys are lit. Next, when the key KIO (shown in Figure 3) is operated to start key operation,
The key KIO goes out, and the number 9 lights up on the numeric keys KO~ for inputting the code signal. Therefore, the user
Press the numeric keys KO~ to select 9.

The number of digits for this code input is determined in advance. If a code signal is input to display the full information menu,
The microprocessor 25'/d switches the data identification signal of the television receiver. Thereby, the television receiver extracts data regarding the full information menu from the transmitted signal and displays it on the screen.

The full information menu is displayed on the screen, for example, as follows: 1° Hobbies, 2° Entertainment, 3° Care, 4° Travel, and 5° Learning. Here, which information menu to select from among all the information menus can be indicated by the number attached to the displayed content. All you have to do is use the number keys. Therefore, the microprocessor 25 uses the numeric key K.
The decoder 26 receives data for displaying 9 on O~.
give to In this case, if you know in advance that the types (numbers) of all information menus are 5, press the number keys 7 to 5.
Data for lighting only the light is given to the decoder 26.

Next, when the user operates the number key 2, the microprocessor 25 determines this and controls the television receiver to extract data regarding the specific event from the transmitted data and display it. This allows the second
As shown in step S2 in the figure, for example, 1. concert), 2. Exhibition, 3. Festival, 4. It is displayed like a movie.

In this case, the user's next operation is to operate the key corresponding to the number attached to the name of the displayed specific missed item. Therefore, in this case, the microprocessor 25 selects the numeric key KO- which allows the next operation.
The data to turn on the light is given to the decoder 26.

Here, the user wants to search for movies, so he operates the number key 4. The microprocessor 25 determines this and controls the television receiver to extract and display data related to the movie from the transmitted data. As a result, the second
Like the Stella FS3 shown in the figure, it can display the location.1. Area A, 2° Area B, 3. It will be displayed as Area C. In this case as well, the user only has to operate the key corresponding to the number assigned to the desired area. Therefore, the number 9 is illuminated on the numeric key KO~.

Here, the user operates the number keys corresponding to the desired area. As a result, the contents of the movie are displayed on the screen as in step S4 of FIG. 2, for example, 1° animation, 2. It is displayed as SF, 3° document, and so on. In this case as well, each movie is numbered, so press the number key KO.
9 lights up in ~.

Here, the user operates the number key 2.

By this operation, an introduction to the screening period will be displayed on the screen, as shown in Figure 2 for Stella 76S5, for example, January to March, February, April to June. , 3.
It is displayed as July/September, 4°October-December, and so on. In this case as well, since each screening period is numbered, the number 9 lights up on the numeric key KO-.

Here, the user operates the number key 3.

By this operation, step s6 in FIG. 2 appears on the screen.
The screening contents will be displayed as shown below. Therefore,
The user can learn what kind of science fiction movies will be released from July to September in the A region based on the initial objective. At the end of such operations, the key Kll is operated.

When the key Kll is operated, the microprocessor 26
outputs the data needed to set the key display to its initial state and all keys to the lit state.

FIG. 4 shows an operating circuit of the microprocessor 25 that performs the above-described key display control.

The data from the receiving circuit 24 is sent to the microprocessor 2.
5 to the input path 40 through the input port 5. This input path 40 is connected to a key KI via a dirt circuit 4.
A determination circuit 42 for determining the O signal is connected. When the key KJO is pressed, the judgment circuit 42
obtains the determination output, and makes the dart circuit 4J non-conductive and the dirt circuit 44 conductive via the inverter 43. As a result, the code determination circuit 45 and the input path 40 are connected.

For example, when a user inputs a code signal requesting a full information menu introduction by key operation, this code signal is
It is decoded by the code determination circuit 45. At this time,
The code determination circuit 46 is a circuit 46 for introducing all information
gives a start signal to. When the full information menu introduction circuit 46 receives the activation signal, it generates a control signal for the television receiver and also provides a data readout signal to the numeric key lighting data generation circuit 47. Therefore, in this case, as explained above, all information menus are displayed with numbers on the screen, and the number key KO- is pressed to 9.
The lighting instruction data is outputted via the output path 48.

In this case, the user requested a full information menu, but depending on the content of the code signal, for example, information regarding a movie in the event could be directly requested.

The code signal determination result at this time activates the item selection circuit 50.

The item selection circuit 50 selects, according to the determination result of the code signal,
1 out of 5 memory for hobbies, 52 memory for entertainment, 53 memory for derms, 54 memory for travel, and 55 memory for learning.
Select one.

The explanation will be given assuming that the event memory 52 is currently selected. Events include concerts, exhibitions, festivals,
A movie is planned. In this case, since the request for information regarding the movie was made in advance, the address data generation circuit 56 generates address designation data in which guide data for requesting movie information and thumbnail lighting key data are stored based on the code signal. Occur.

Thus, the state of the movie information request corresponds to step S3 in FIG. Therefore, the output path 48 outputs data for instructing the lighting of the numeric keys.

Furthermore, the data on the output path 48 is transferred to the data comparison circuit 57.
is also entered. On the other hand, this comparison circuit 57 is also supplied with output data from a selection key determination circuit 58 . The selection key determination circuit 58 is a circuit that determines the data input via the buffer circuit 59 when the user operates a key, generates designated data corresponding to the operated key, and supplies this to the comparison circuit 57. It is. The buffer circuit 59 establishes conduction between the input buffer 40 and the selection key determination circuit 50 when the code determination circuit 45 has finished determining the first code signal.

The comparison circuit 57 compares the next operable key instruction data with the designation data of the key selected and operated by the user, and determines whether data from the user exists in the data output from the memory 52. Determine whether Finally, the user determines whether or not the user has operated the key indicated by the microprocessor 25. If the comparison circuit 570 determines that the user's operation is incorrect, it outputs a warning signal, and if it is correct, it provides a pulse to the address data generation circuit 56. As a result, the address data generation circuit 56 outputs address designation data for instructing the next operable key.

The memory 52 sequentially stores data for instructing operation keys in accordance with each request information. Therefore, if the output data of the address data generation circuit 56 is increased as key operations are performed, data for instructing the next operable key is output.

After the user obtains the desired information, the key Kll is operated. This is determined by the key "K77 determination circuit 60. When the determination circuit 6o determines that the key Kll has been operated, it outputs a signal that sets the circuit system of FIG. 4 to the initial state.

In the memory 52, data for instructing the operation keys is stored in advance with addresses classified for each operation step. The emotion desired by the user.

Since the keys that can be operated are known in advance according to the information, a read-only memory in which instruction data is arranged in advance may be used in the memory 52, but the information provided and the search method may be changed. For convenience, it is preferable to use random access memory so that data can be written by transmission.

〔Effect of the invention〕

As described above, according to the present invention, since the next key to be operated can be indicated by the light emitting means, the number of operation errors can be significantly reduced. Further, even if a user is inexperienced in operation, he or she can obtain some results by operating according to the instructions, and it is possible to prevent the user from mistakenly assuming that the system is malfunctioning.
