Abstract

PURPOSE:To reduce burden by allowing acquisition of necessary screen information for reading out memory storage data in case of screen information once selected when pressing a repeat key. CONSTITUTION:When the same screen information is needed, a repeat key 14d of a key operation part 14 is operated. When the key 14d is operated, a timing circuit 20 generates read out address specified data corresponding to a memory 18, sends out the data read out from the memory 18 to a parallel-serial converter 21 to convert the parallel data into serial data, and input the serial data into a remote control signal generator 13. Therefore, the operating of the key 14d saves unnecessary operation of a number of keys.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a programmable receiving device, in which, for example, a desired channel can be selected from among the television signals of many channels transmitted using a telephone port. Used when receiving a message that is not selected.

[Technical background of the invention and its problems]

Systems have been developed that can send and receive television signals using telephone lines, but in these systems,
It is possible to transmit screen information of tens to hundreds of blades. On the other hand, on the receiving side, one desired piece of screen information is selected from among the many pieces of screen information. Here, in order to select the desired screen information, it is necessary to input a code signal into the receiving circuit by operating 6 to 10 digit keys on the keyboard, for example. Therefore, a problem arises in that the user must perform many key operations each time the reception screen is changed. In particular, if you want to obtain the same screen information every time, or if you want to obtain the same screen information every time, you may have to press the same keys each time, which may cause problems such as loss of an hour at the expense of the user. be.

As mentioned above, many key operations are required to obtain essential information. Further, this type of so-called captain system may be installed in banks, government offices, etc. In this case, the required information is often the same information each time. Therefore, retrieving the same information by performing the same operation each time becomes a burden and wastes time.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a programmable receiving device that can reduce the number of key operations required by the user and improve the operational burden.

[Summary of the invention]

In the present invention, the repeat key 14d replaces the need to perform a large number of key operations on the key operation section 14 in order to display necessary screen information in a captain system or the like.
If you press , memory 18 will be saved if the screen information is selected once.
By reading out the stored data, necessary screen information can be obtained with a single operation, thereby reducing the operational burden on the user.

[Embodiments of the invention]

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

FIG. 2 shows an embodiment of the present invention, and 11 is a receiver body including a received signal processing section and a display screen section. The received signal processing of this receiver main body 11 is controlled by a remote control system. 12 has a remote control signal generating section 13 (6L in the i section).This remote control signal generating section 13t1-4 generates a control signal in accordance with key manual data from the key operation section 14. .

This remote control system has a key operation section 14.
Screen selection can be performed by performing key operations.

The output of the key operation section 14 is input directly to the remote control signal generation section 13 and also to the serial/parallel converter 15.

The serial/e-parallel converter 15 converts input data into, for example, byte-configured parallel data. The output data of the serial-parallel converter 15 is sent to the memory key determination circuit 16.
, is input to the repeat key data determination circuit 19.

The memory key data determination circuit 16 is a circuit that determines whether or not the memory key 14TA of the key operation unit 14 has been operated. If the memory key 14h has been operated, the memory key data determination circuit 16 is a circuit that determines whether or not the memory key 14TA of the key operation unit 14 has been operated. Intake,
The signal is sent to the timing circuit 17. The timing circuit 17 is provided with a screen selection start key data determination circuit and a screen selection end key data determination circuit. Therefore, when the memory key 14 a 7 > is input into the memory 18. Here, when the user presses the memory key 14 & again, a 1 writing pulse is given to the memory 18 and data writing is completed. The screen selection operation key data is generated by operating the screen selection end key 14c. Therefore, if you press the memory key 14fL for the first time and then perform a screen selection operation, the selected image report will be displayed on the receiver body 1.
screen selection data etc. are stored in memory 1.
8 will be stored.

Next, if the same screen information is required again, the repeat key 14d of the key operation section 4 is operated. The repeat key data determining circuit 19 determines whether the repeat key 14d has been operated or not. When the repeat key 14d is operated, the judgment data of the repeat key data judgment circuit 19 is input to the timing circuit 20.

When the timing circuit 20 receives judgment data indicating that the repeat key 14d has been operated, it generates read address designation data for the previous memory 18 and sends the data read from the memory 18 to the parallel-serial converter 21. do. Parallel serial converter 2 is
- Convert the motherboard data into serial data and input it to the remote control signal generator 13.

Therefore, if the repeat key 14df is operated, there is no need to perform many key operations similar to the previous one.

22 is a clock generation circuit, the output of which is input to the counter 23; The counter 23 includes various clocks and clocks.
A signal is generated and applied to the serial/parallel converter 15, the parallel/serial converter 2, the timing circuits 17, 20, etc.

FIG. 3 shows the timing circuit 17 in more detail.

In the dirt circuit 171, when judgment data indicating that the memory key 14a has been operated is inputted to the terminal 17a from the memory key data judgment circuit 16, the input and output terminals are electrically connected. As a result, the memory-key data determination circuit 16
Data from the serial-parallel converter 15 is accepted throughout. The data output from the dart circuit 17 is input to the write circuit NORA 4 via a screen selection end determination circuit 172 and a screen selection start determination circuit 173.

Screen selection end determination circuit 172, screen selection start determination circuit 1
Reference numeral 73 denotes a circuit for inspecting each key data generated when the screen selection start key 14b and the screen selection end key 14c are operated.

The screen selection start key data is determined by the screen selection start determination circuit 17.
3, the detection signal is detected by counter 1
75 as a start signal. counter 175
When the start signal is input, it counts the clock pulses and pulses from the clock generation counter 23 described above, and supplies the count data to the memory 18 as write address designation data. As a result, the screen selection data is stored in the memory 18. Next, when the screen selection end data is detected by the screen selection end determination circuit 172, the detection signal stops the operation of the counter 125. Further, the memory saving circuit 174 controls the counter 175 so that the counting operation of the counter 175 advances every time one byte of write data is completed and writing is performed.

FIG. 4 shows more specifically the timing circuit 20 for reading the data of the memo IJ j B when the repeat key 14d is operated.

When the repeat key 14d is operated, the repeat key data determination circuit 16 detects this and provides the detection output to the screen selection start data determination circuit 201. When the repeat key data detection signal is input, the screen selection start data determination circuit 20 resets and starts the address counter 204 and becomes capable of accepting data from the memory 18. Address counter 204 generates read addressing data for memory 18 . As a result, data is read from the memory 18 and input to the screen selection start data determination circuit 201.

When the screen selection start data determination circuit 201 detects the screen selection start data read out from the memory 18 , the screen selection start data determination circuit 201 sends subsequent data to the parallel/serial conversion circuit 21 through the screen selection end data determination circuit 202 and the dart circuit 203 . do.

In this way, the screen selection data is read out one after another from the memo horn 8, and when the screen selection end data is finally read out, this data is detected by the screen selection end data determination circuit 202.

When the screen selection end data determining circuit 202 detects the screen selection end data, it controls the dart circuit 203 to an anisotropic state and also sets the time elapsed counter 205. The time elapsed counter 205 is the address counter 204.
is reset, and all operations of the address counter 204 are prohibited for a certain period of time. This is to prevent the next unnecessary data from being read out from the memory 18 until the image selection is completed on the reception main body 11 side. The address counter 204 and the hour 1Bj elapsed counter 205 are supplied with a clock from the clock generation counter 23 described above.

FIG. 5 is a flowchart for explaining the operation of the programmable receiver described above.

That is, when the cloth 1 source is turned on, it is determined whether the remote control transmission/reception line is turned on. Step S2, then step S3, it is determined whether the memory key 14a has been pressed, and if the memory key 14h has been pressed, the process moves to step S4, and whether or not the screen selection start key 14b has been pressed. A judgment will be made.

If the screen selection start key 14b is pressed, step S
In step S5, a data filling process is performed, and the process moves to step S6. In step S6, it is determined whether or not the m'Efii selection end key 14a has been pressed, and if the screen selection end key 14c has been pressed, the generation of at and responses to the memory is stopped in step S7. be done. and,
In step S8, it is determined whether the memory key 14m has been pressed again. If the memory key 14a has been pressed, the process moves to step S9, the operation of the memory is stopped, and the process returns to step S3.

Whether or not the repeat key 14d has been pressed is determined by the S1
If it is determined at θ and the repeat key 14d is pressed, the process moves to step S11. In step S11, data is read from the memory. Then, in step S12, it is determined whether or not there is screen selection start key data. If there is no screen selection start key data, this means that no data is stored in the memory, so the repeat circuit operation is stopped in step 816, and the process returns to step S3. If screen selection start key data exists, the process moves to step S13, where it is determined whether or not screen selection end key data exists.

If screen selection end keep--even exists, all data is sent in step S17, and step S1
4, the generation of memory ref is stopped, the clock is counted by Stella fsxs until a predetermined period of time has elapsed, and the process returns to step S1.

In the embodiment described above, the present invention is applied to the remote control transmitter 12, but it may also be provided in the rectangle 11 of the receiver main body 11.

Figure 6 shows an example where the receiver is installed on the 1 side of the receiver body.
The signal transmitted from the remote control transmitter 12 is received by the remote control signal receiver 30. The received No. 18 is input to the serial-parallel converter 31. This serial-parallel converter 3 corresponds to and is a similar circuit to the serial-parallel converter 5 shown in FIG. The output of the serial/parallel converter 3 is led to a remote control signal processing section via an output terminal 37 and is also input to a repeat key data determination circuit 35 and a memory key data determination circuit 32.

This memory key data determination circuit 32 is a circuit similar to the memory key data determination circuit 16 in FIG. 2, and the repeat key data determination circuit 35 is similar to the repeat key data determination circuit 19 in FIG. It is a circuit. The output of the memory key data determination circuit 32 is input to the timing circuit 33. This timing circuit 33 also
A circuit similar to the timing circuit 17 shown in FIG. 2 is used.

Therefore, when the memory key is pressed and pressed to select a screen in the remote control transmitter 12, the data at that time is stored in the memory 34. Also,
When the key data is stored in the screen selection in the menu 34, the repeat key is selected in the remote control transmitter 12 (if 11 is created, this will be replayed) -S-data judgment foot The circuit 35 makes the decision and provides the decision output to the total timing circuit 36. This timing circuit 3
6 is a circuit similar to the timing circuit 20 shown in FIG. 2, and can output the data kfb+ of the memory 34 and guide it to the remote control signal processing section. 38 is
This is a clock generation circuit. FIG. 7 is a diagram showing the operating procedure of the above system, which is almost the same as the flowchart of FIG. 5. In the case of FIG. 7, a step S20 for determining whether or not a remote control signal is being received is simply added between Stellar fs2 and S3.
The other steps are the same as in FIG.
